Abstract Oil chromatographic analysis is widely used in transformer fault diagnosis However, the problem of excessive total hydrocarbons in the oil chromatogram caused by the failure of the transformer submersible pump is different from the failure of the transformer body. Technicians need to be able to accurately identify these two types of failure. For this problem, this article proposes a method of judging by manually starting and stopping the submersible pump and monitoring the change law of the transformer chromatographic data. This article first finds out suspicious submersible pumps through current data. Subsequently, the operator starts and stops the submersible pump and monitors the change law of the transformer chromatographic data. From this, the correlation between the start or stop of the submersible pump and the chromatographic data was found. Finally, the effectiveness of this method is verified by the submersible pump disassembly inspection and simulated live test.

Проанализировано применение погружных (плавающих) насосов в насосно-рукавных комплексах. Рассмотрены их преимущества перед центробежными насосами, устанавливаемыми в мобильной пожарной технике. На основе практики применения и технических характеристик погружных насосов, производимых ведущими зарубежными фирмами, сформулированы технические требования для разработки отечественного погружного насоса. Кроме того, технические требования могут стать основой разработки национального стандарта для этого типа пожарно-технической продукции. The article analyzes the results of operation of a relatively new type of centrifugal pump - a submersible (floating) centrifugal pump with a hydraulic drive. These pumps have a number of significant advantages over centrifugal pumps installed on mobile fire fighting equipment - they can be used to pump liquid from a mark up to minus 30 m. Since the suction pipe of such a pump is located directly in the pumped liquid (below the liquid mirror level), the phenomenon of cavitation is practically excluded. Submersible pumps are used to supply water in case of fire and for water disposal during the elimination of hazardous hydrological phenomena, both independently and in conjunction with centrifugal pumps installed on mobile fire fighting equipment (supply to pumping). All submersible pumps included in the set of hose-pumping complexes are of foreign production. The demand for such pumping units causes the need to develop domestic samples in order to get away from import dependence in the manufacture of pumping and hose systems and their operation. Based on the practice of using submersible pumps and the technical characteristics of submersible pumps produced by leading foreign companies, the following technical requirements for the development of a domestic submersible pump have been formulated. Pump delivery is 170-180 l ∙ s from the mark to minus 30 m. Water intake is possible both in equipped (adapted) and unequipped (unsuitable) places. In addition, the requirements for the hydraulic drive, weight and size characteristics, and some components have been formulated. In conclusion, some directions for the further development of pumping and hose systems and submersible pumping stations are considered.

Abstract The study of axial force has been a hot spot in fluid mechanics research, and the magnitude of axial force directly affects the stability, safety, and efficiency of submersible pumps. This paper takes 200QJ50 multistage centrifugal submersible pump with spatial guide vane as the research object, simulates and numerically calculates the internal flow field of multistage submersible pump based on Standard k-ε turbulence model, a SIMPLE algorithm, and high-resolution format through CFX software, analyzes the distribution law of static pressure and velocity field of the multistage submersible pump under 0.7Qd , 0.8Qd , 0.9Qd , 1.0Qd and 1.1Qd working conditions and compared the theoretical and simulated values of the corresponding axial force for each working condition. The results show that with the increase of the flow rate, the axial force of the multistage submersible pump shows a downward trend; the axial force generated by the first stage impeller has a larger proportion, and reaches the maximum value in the design condition; the traditional axial force calculation formula can more accurately predict the axial force under the design condition, and the error is 6%. The results of this study can provide references for the design and optimization of multistage centrifugal submersible pumps.

Modern oil extracting has difficulties with extraction at depths exceeding 2 kilometers from mid and low debit wells. Traditional way for extraction from mid and low debit wells (pumping unit) is unacceptable for this task, because of rod column break hazard. Meanwhile, submersible electrical centrifugal pumps that are usually used for oil extracting from big depth have very low efficiency on low debit wells. Due to that, a new class of oil extraction equipment has appeared—submersible plunger pumps. Their world-leading manufacturer is China. The biggest progress in submersible plunger pump linear drive research was reached in Perm National Research Polytechnic University. Although efficiency of this type of pumps on low debit wells is much higher than centrifugal pumps have, it is still very low and does not exceed 30%. Thus, efficiency improvement of gaining popularity submersible plunger pumps is an important task not only for oil extraction but also for energy saving. Major power loss happens in windings of submersible linear motors. Because of that, first step of pump efficiency improvement is improvement of linear drive efficiency. Motor design optimization allows to significantly raise its efficiency to 50%. Higher efficiency could be reached by optimizing motor operation algorithm and using better materials.

This service activity is the application of an innovative submersible solar pump in a hydro-organic greenhouse environment in Grangsil Jambangan, Malang Regency. This is motivated by the need for water that can only be obtained through deep wells with submersible pumps in hydro-organic greenhouses that already use solar power plants but have insufficient power. The purpose of this service is to provide theoretical and practical understanding for Tour conscious group (POKDARWIS) Jambangan members as managers of the hydro-organic greenhouse. The methods used include focus group discussions (FGD) and joint practice in developing solar power plants for submersible pumps. After the implementation of this program, there was an increase in the capacity of the solar power plants, which has been able to turn on submersible pumps, hydroganic circulation pumps, and other needs. In one day, the submersible pump only needs to be turned on for 2 hours and produces 4,572 liters of water, sufficient for greenhouse hydroganic needs and other needs. Another positive impact is that POKDARWIS Jambangan members have been able to manage and maintain PLTS for a hydro-organic greenhouse. The submersible water pump prototype for hydroganic agriculture at the greenhouse using independent energy is very practical and efficient so it is expected to become a prototype for modern agricultural facilities in the context of a national-scale food security improvement program.

One of the biggest problems for farmers in the dry season is the lack of water supply for irrigation. Currently, various types of pumps have been widely used, such as fuel pumps and pumps with PLN electricity. However, the costs required to operate these tools are pretty expensive. The solution to overcome this is using DC submersible pumps using solar panels as an energy source. The purposes of this study are to (1) determine the duration of operation of the DC submersible pump with the specifications of the battery and solar panels used, and (2) determine the productivity of the DC submersible pump in terms of the resulting discharge for various storage height conditions used. The research method used is an experimental research method using a quantitative approach. The results of this study are (1) DC submersible pump can operate for 240 minutes with 20 Ah battery at maximum voltage and uses 60 Wp solar panels, and (2) the height of the storage has an effect on the resulting discharge, there is a reduction in the resulting discharge every 0.5 meters increase in the height of the storage. Based on the analysis results, the maximum height limit for submersible pump push is 3.7 meters using a 3 per 4 inch hose. The results of this study can be a reference for farmers or users to determine the height of the water storage.

“Salt deposition in a centrifugal pump under intermittent operation” is the first article to address the cause of failures among electric submersible centrifugal pumps operating intermittently. The causes of said failures are analyzed. The failure of electric submersible centrifugal pumps is caused by their temperature behavior during operation. The problem of the thermal condition of a centrifugal pump under intermittent operation must be solved. Moreover, the number of failures caused by salt deposition or the electric resistance drop of the “cable – motor” system can be reduced.

The difficulty in directly determining the failure mode of the submersible screw pump will shorten the life of the system and the normal production of the oil well. This thesis aims to identify the fault forms of submersible screw pump accurately and efficiently, and proposes a fault diagnosis method of the submersible screw pump based on random forest. HDFS storage system and MapReduce processing system are established based on Hadoop big data processing platform; Furthermore, the Bagging algorithm is used to collect the training set data. Also, this thesis adopts the CART method to establish the sample library and the decision trees for a random forest model. Six continuous variables, four categorical variables and fault categories of submersible screw pump oil production system are used for training the decision trees. As several decision trees constitute a random forest model, the parameters to be tested are input into the random forest models, and various types of decision trees are used to determine the failure category in the submersible screw pump. It has been verified that the accuracy rate of fault diagnosis is 92.86%. This thesis can provide some meaningful guidance for timely detection of the causes of downhole unit failures, reducing oil well production losses, and accelerating the promotion and application of submersible screw pumps in oil fields.

Artificial Lift is a very essential tool to increase the oil production rate or lift the oil column in the wellbore up to the surface. Artificial lift is the key in case of bottom hole pressure is not sufficient to produce oil from the reservoir to the surface. So, a complete study is carried to select the suitable type of artificial lift according to the reservoir and wellbore conditions like water production, sand production, solution gas-oil ratio, and surface area available at the surface. Besides, the maintenance cost and volume of produced oil have an essential part in the selection of the type of artificial lift tool. Artificial lift tools have several types such as Sucker Rod Pump, Gas Lift, Hydraulic Pump, Progressive Cavity Pump, Jet Pump, and Electrical Submersible Pump. All these types require specific conditions for subsurface and surface parameters to apply in oil wells. This paper will study the Electrical Submersible Pump “ESP” which is considered one of the most familiar types of artificial lifts in the whole world. Electrical Submersible Pump “ESP” is the most widely used for huge oil volumes. In contrast, ESP has high maintenance and workover cost. Finally, this paper will discuss a case study for the Electrical Submersible pump “ESP” design in an oil well. This case study includes the entire well and reservoir properties involving fluid properties to be applied using Prosper software. The results of the design model will impact oil productivity and future performance of oil well.

Discusses the negative manifestations in the operation of water intaking constructions from underground. In the mode of operation of each pump is influenced by external and internal characteristics of the system wells – submersible pump – common culvert – the clean water tank. Methods Mathematical model operation of management process of collaboration of system a water well – a prefabricated conduit with definite forms of boundary conditions. Schemes of an arrangement are shown of water wells and a prefabricated conduit. Results Interference of a duty of certain wells and a prefabricated conduit is studied, unstable work of submersible pumps is defined. The scheme of water delivery is presented to the pure tank on separate pressure pressure lines. To ensure the stability of the pumping equipment, the characteristics of the diameter of the water conduit (its hydraulic resistance) are determined depending on the total hydraulic resistance of the well equipment (well filter, pump, fittings) and the well pipeline. Monitoring of water intake structures allows you to set technical indicators for choosing an independent scheme, to choose the right equipment, taking into account the joint operation of the system borehole - submersible pump - collecting water conduit - RFI. Conclusion Energetically optimal work of water intake structures with separate pressure lines, helps to reduce water losses, while achieving significant savings in electricity. The most favorable for the submersible pump is work on the clean water tank, and not on the prefabricated conduit.

The reducing in the pressure characteristic of the submersible pump during operation occurs as a result of the combined action of a number of reasons. Pumping equipment wears out due to waterjet destruction of flow channels. The characteristics of submersible pumps are captured at the factory on special stands. At large group groundwater intakes, wells are equipped with an automated control system that allows testing the pump at the workplace and promptly making a decision on its replacement if the pressure characteristic is unacceptably reduced. The actual pressure characteristic of the pump H н = f (Q) can be plotted directly in the well with a sufficient degree of accuracy. To determine the degree of wear of the pump, its pressure characteristics are compared before installation and at the time of taking readings. The article describes a well strapping scheme for measuring the specific flow rate and pressure characteristics of a submersible pump. The purpose of the study is to derive a dependency for constructing the flow-pressure characteristics of a submersible pump at its workplace and to develop a method for accounting for its wear during operation, which allows predicting a decrease in well productivity over time. An expression is proposed to describe the characteristics of the pump at any time, calculated from its installation in the well. The analysis of the reducing in the pressure characteristics of pumps produced by various manufacturers in the wells of the existing water intake of underground water is presented. It is confirmed that the intensity of the pressure reduction depends on the duration of the pump operation in a given well, the material of the pump impellers and the sand content in the pumped water.

Abstract Electric submersible screw pump often works at high speed, which has the characteristics of high speed, high temperature and large rubber deformation. In case of sudden shutdown, the rubber will not shrink at high temperature, which may lead to serious accidents such as pump locking and electrode burning. In the initial stage of pump start-up and restart after pump shutdown, due to the above reasons, it is often difficult to start the pump, which makes the pump unable to work normally. Therefore, this paper studies the clearance value of the electric submersible screw pump, calculates and tests the interference amount and initial interference amount, improves and optimizes the clearance value of the electric submersible screw pump, effectively improves the working efficiency and service life of the electric submersible screw pump, achieves the purpose of improving the quality and efficiency of oilfield production, and has a very important practical significance for the development of the rodless pump market.

Global warming has led to lower levels of the water basins. Groundwater levels also decrease. Sometimes they fall so much so that submersible pumps in the wells remain almost dry and even in short work cycles get damaged. Their repairs are very expensive and labour intensive. An algorithm for management and protection of submersible pump is proposed in the paper. It uses 5 level sensors. It allows full utilization of the wells capacity and protects the pump motors from premature wear due to frequent switching on and off.

The diffuser inlet width is a key geometric parameter that affects submersible pump performance. On the basis of diffuser characteristic curve analyses, diffusers with different inlet widths and the same impeller were equipped to construct a submersible pump model through the use of AutoCAD software. The performance curves of the submersible pump, with six diffuser inlet widths, were obtained using computational fluid dynamics method. Simultaneously, the simulation results were tested with the experimental method presented in this article. The results show that the optimum value of the inlet width ( b3 = 50 mm) is larger than the experience-based one. With an increase in the inlet width, the optimum operating point of a submersible pump offsets to a larger flow rate. When the guide blade inlet width is approximately 40–55 mm, the submersible pump efficiency is relatively high, approximately 75.9%–83.7% capacity, and the flow rate is approximately 105–135 m3/h. The numerical results of submersible pump performance are higher than those of the test results; however, their change trends have an acceptable agreement with each other. The practical significance is supplied by changing the inlet width of the diffuser to expand the scope of use.

This study presents a new gas-liquid model to predict electrical submersible pumps head performance. The newly derived approach based on gas-liquid momentum equations along pump channels has improved the Sachdeva model (Sachdeva, R., Doty, D. R., and Schmidt, Z., 1988, “Two-Phase Flow through Electrical Submersible Pumps,” Ph.D. dissertation, The University of Tulsa, Oklahoma; 1994, “Performance of Electric Submersible Pumps in Gassy Wells,” SPE Prod. Facil., 9, pp. 55–60) in the petroleum industry and generalized the Minemura model (Minemura, K., Uchiyama, T., Shoda, S. and Kazuyuki, E., 1998, “Prediction of Air-Water Two-Phase Flow Performance of a Centrifugal Pump Based on One-Dimensional Two-Fluid Model,” ASME J. Fluids. Eng., 120, pp. 327–334) in the nuclear industry. The new two-phase model includes novel approaches for wall frictional losses for each phase using a gas-liquid stratified assumption and existing correlations, a new shock loss model incorporating rotational speeds, a new correlation for drag coefficient and interfacial characteristic length effects by fitting the model results with experimental data, and an algorithm to solve the model equations. The model can predict pressure and void fraction distributions along impellers and diffusers in addition to the pump head performance curve under different fluid properties, pump intake conditions, and rotational speeds.

With the rapid development of the offshore oil industry, electric submersible pumps have become more and more important. They are the main pumping equipment in oil well production and have huge advantages in terms of displacement and production costs. Due to the complex structure of the electric submersible pump, the bad working environment will cause failures. The failure of tubing string leakage is a common failure in oilfields; tubing string leakage of the electric submersible pump will reduce oil production. In order to reduce the economic loss of oil well production. This paper uses PCA and Mahalanobis distance to make the tubing Fault diagnosis of leakage. The feasibility of the algorithm is verified through experiments. The result shows that it can diagnose the failure time of pipe string leakage in advance and hence help us to reduce the maintenance cost of offshore oilfields.

Oil production is a complex technological process that requires significant electricity consumption. The main electricity consumers in oil and gas production workshops are artificial lift facilities. Currently, among the objects of mechanized mining, installations of electric submersible pumps are widespread. When planning technological modes, it is necessary to be able to assess the change in the power consumption parameters when changing the technological process parameters. The paper proposes a typical replacement scheme for the electrical complex element. The power consumption calculation of electric submersible pump installations has been carried out. The error in the power consumption modeling results of electric submersible pump installations in comparison with the results of instrumental measurements is no more than 10%. The estimation of additional losses of electric energy caused by the influence of harmonics is carried out. The proposed technique makes it possible to estimate the power consumption of an electric submersible pump installation when changing the parameters of the technological process and equipment. The results of the work can be used for planning material support and optimization of warehouse stocks within the framework of integrated logistics support for the technological process of industrial enterprises.

Water collection based on groundwater abstraction has a high energy consumption that depends primarily on the operation and performance of submersible well pumps. The fact of the matter is that these machines still work with a global energy efficiency of less than 50%, and further investigations of the energy aspects in well pumps are needed. The present study introduces measures to increase the global efficiency of submersible well pumps linked to electrical energy savings. Common submersible pumps with asynchronous motors (ASMs) were compared with innovative permanent magnet synchronous motor (PMSM) technology in real well fields in Berlin and Hamburg waterworks. This study confirms that PMSM pumps showed a 6.8%-points higher global efficiency compared to ASM pumps at optimal working points. The investigation of the impact of well field operation on local pump efficiency offers an additional increase in the global efficiency. In this context, the influence of variable speed control on the global efficiency and the energy consumption was analyzed. Global efficiencies of over 70%, and potential energy savings of up to 20%, were determined for the speed-controlled PMSM pump. This offers water suppliers new incentives to optimize their water collection systems for less energy consumption.

The article is devoted to the issue of control and regulation of the high-quality operation of a submersible motor with a long overhaul period. There are some complications of operating the electric submersible pump. One of them is the thermal interaction of the borehole fluid and components and parts of the electric submersible pump that leads to failure and repair. It is necessary to conduct research in the field of physical and hydrodynamic calculations to determine the effect of heat exposure. The article reveals one of the approaches to solving the problem of thermal interaction between a well and the electric submersible pump. We describe calculations of the winding temperature of a submersible electric motor for specific conditions in a particular well, including different modes of fluid flow, different loads of the submersible motor, and different concentrations of oil in water. The development of the described technique will allow creating special software aimed at determining the areas with the highest temperature of the motor winding, taking into account various parameters that affect the heat transfer process.

Abstract The current coverage of oil wells with telemetry does not allow timely determination of deviations in the operation of about 40% of electric submersible pumps. To solve this problem, a model of virtual sensors has been developed that allows the prediction of temperature and pressure growth at the pump intake in the absence of submersible sensors based on modern big data processing and machine learning technologies. The developed models of virtual sensors are embedded directly into the process control system, which allows notifying the technologists and operators about a possible reduction in the planned average pump operating time and their possible failures for various reasons.

Hydroponic systems in plant factories can be categorized into recirculating or noncirculating systems. In this study, the effects of various commercially available circulation pumps, including a centrifugal magnetic drive pump, a regenerative self-priming pump, and a submersible pump, were experimentally explored. In addition, the effects of an ultraviolet sterilization system on the ion concentrations in nutrient solutions were examined. The concentrations of sodium, potassium, magnesium, calcium, nitrate, sulfate, and ferric (Fe3+) ions in the nutrient solution were measured. For all three types of pumps, the results indicated that there was no significant effect on the concentrations of ions in the nutrient solution. However, the concentration of Fe3+ ions decreased significantly after the nutrient solution was treated by a ultraviolet sterilization system for 48 hours. In addition, the effects of the three types of pumps on the growth of butterhead lettuce (Lactuca sativa) were examined. The temperature records during the pump circulation tests showed that the nutrient solution temperature of the regenerative self-priming pump increased by 15.5 °C (from 20.5 to 36 °C), which caused yellow seedling, scorching on the leaves, and browning of the roots. The ion concentration in the nutrient solutions and total fresh weight of butterhead lettuce did not show any noticeable difference between the centrifugal magnetic drive pump and the submersible pump. In this paper, we clarify the cause of the decreasing iron concentration and provide a guideline for selecting the pump for circulating hydroponic systems in plant factories.

Submersible motors are part of submersible oil production pumps that convert electrical energy, which is supplied through a cable from VSD, into mechanical energy of pump rotation. Currently, in about 30% of cases, the failure of an electrical submersible pump is due to a failure of the submersible motor. One of the main causes of failures is overheating of the stator winding insulation. Overheating of submersible oil-filled electric motors occurs because more heat is generated inside the motor than is removed through its outer surface. To intensify the heat removal, it is proposed to connect a heat exchanger in series with the motor and to organize the circulation of the oil in a closed loop. Both in the submersible motor and in the heat exchanger, oil flows along the annular gap along the inner surface of the housing, the oil channel is closed through a hole inside the shaft. The aim of the work is to select such a configuration of the annular channel, in which its length would be minimal. Intensification of heat removal by increasing the speed of the coolant is not advisable, because requires the motor to be equipped with a powerful pump for pumping oil, which will become an additional source of heat. Therefore, it was decided to increase the surface area of the annular channel through which heat, through the body of the installation, is removed to the well fluid. A series of calculations was performed for heat exchangers with smooth walls, with fins (perpendicular to the flow direction), and with spiral grooves (which additionally increase the length of the trajectory of oil particles and the time of their thermal contact with the stacks of the heat exchanger body). Computational fluid dynamics calculations showed that heat exchangers made according to the first two design options removed less than half of the heat. According to the third option, the oil was cooled practically to the temperature of the well fluid with a heat exchanger length of about 10% of the submersible motor length.

Objectives Investigate the prospect of improving the quality of centrifugal pumps in oil production.Method The method is based on energy-efficient installations for high-yield wells - the steps of the Borets-Weatherford installations and the Borets PC stages.Result The main hydraulic characteristics of electric centrifugal pumps with the use of energy-efficient stages with the recommended feed range have been developed. The dependence of the maximum efficiency on the applied steps of the above installations has been determined. A comparative analysis of energy-efficient and commercially available installation of electric centrifugal pumps is given. The dependence of the parameters of the installation steps on the flow, head, number of stages, nominal speed and efficiency of the pump is given.Conclusion When using submersible pumps of the 10ECNM type in oil fields, increased reliability and durability were noted, in contrast to the use of submersible ECNM-type pumps. With the help of energy efficiency programs for oil production, implemented by oil companies, by ensuring more efficient operation of pumping equipment, power consumption has been reduced. The adoption of promising solutions to improve the energy efficiency of ESP systems is a priority. The use of energy-efficient ESP systems for the operation of high-rate and low-rate wells allows to ensure maximum efficiency of the submersible equipment and reduce the specific electricity consumption. In a comparative analysis of the characteristics of pumps with a daily flow of 400 m3, the use of an energyefficient installation ESP 400–2200 with FEA provides three times lower energy costs. A comparative analysis of the energy efficiency of the presented pumps shows that the use of energy-efficient installations of electric centrifugal pumps produced by PC Borets LLC will reduce energy costs by an average of 30%.

The primary goal of every operator is to optimally recover reserves at minimal operating costs. Unfortunately, due to inherent primary drive mechanisms that may not be strong enough and poorly designed completion jewelries that increases the complexity of well configurations, most reservoir are not efficiently depleted. This study investigates the impact of fluid properties on electric submersible pumps (ESP) performance and run life in a well. It was observed that the pump speed increases with increase in API gravities and vice-versa. However, decrease in pump speed was observed with crudes having high API gravity from wells with high water-cut (HBSW). High water-cut increases the viscosity of the crude and thus decreases the pump speed. The pump speed also increased as the GOR increases, howbeit, decreased as the GOR exceeds a certain optimum value due to cavitation. The pump intake pressure and the production rate were also investigated. The higher the intake pressure, the higher the pump speed and thus, the higher the production. Well specific models for real-time ESP performance prediction were also developed for each property against the pumpspeed and they exhibited cubic relationships. It was also observed that the quality of the crude significantly affects the performance of ESP’s and therefore, must be checked to prevent early failure and short run life.

Electrical submersible pumps (ESP) are referred to as a pump classification whose applications arebased upon transporting fluids from submersible elevations towards a fixed pipeline. Specific ESP pumps areutilized in offshore oil and gas facilities that are frequently employed in transport of Liquefied Natural Gas(LNG) terminals. Transport of LNG is a multiphase process that causes operational challenges for ESP due topresence of air pockets and air bubbles; presenting difficulties, such as cavitation and degradation to pumpcomponents. This performance degradation causes an economic risk to companies as well as a risk to pumpperformance capabilities, as it will not be able to pump with the same pressure again. Operational references formultiphase flow in ESP are limited; thus, this research paper reports multistage pumping, review offundamentals, previous experimental as well as modelling work benefitting future literature for a potentialsolution. Industries consume power to cope up with the losses associated with pumping two-phase fluidscausing company’s fortune. Preceding experimental work on single along with multiphase flow illustrate adistinct flow pattern surrounding the area around pump impeller while the pump is in operation. Throughexperimental observation, four flow patterns were observed and studied when gas was varied at different flowrates. Increasing the intake pressure proved to increase pump performance at two-phase flow. Experimentalstudy of multiphase flow with LNG fluid is expensive; thus, experimental validation is accomplished on asingle stage pump with external intervention of air bubbles to simulate LNG vaporization at fixed pressure andtemperature difference.

In order to investigate the internal flow characteristics and hydraulic stability of vertical submersible pump station in forward and reverse operation, the steady and unsteady three-dimensional numerical simulation of vertical submersible axial-flow pump device was carried out based on CFD and the energy performance of the pump device was predicted. In this paper, the internal flow characteristics of the vertical submersible axial-flow pump device under forward and reverse operation were analyzed, and the optimization of the structure passed by water was carried out to improve the efficiency of the pump device in forward and reverse operation. The results show that the performance of the pump device is good when it is running in the forward direction, the peak efficiency of the pump device is 72.22% and the corresponding head is 4.01 m. When it is running in the reverse direction, the performance of the pump device decreases significantly with the peak efficiency is only 36.03% and the corresponding head is 3.34 m. The hydraulic loss in the dust-pan-shaped conduit is very small in the forward operation, the wellbore conduit is the main factor which affects the efficiency of the submersible axial flow pump device, the loss ratio is 12%–44%. When the pump device is in reverse operation, the hydraulic loss is similar but the hydraulic performance is poor and the hydraulic loss is obviously larger than that in forward operation. A guide plate is added to the dust-pan-shaped conduit at 0.27 D ( D is the nominal diameter of impeller) along the axis direction of the conduit, and a elbow flow conduit with the corner radius R of 0.83 D is selected to replace the wellbore conduit, the bad flow state disappeared and the efficiency of the pump device increased by 5.19% in the forward operation while the efficiency of the pump device increased by 9.62% in the reverse operation.

A diffuser acts as an energy conversion device to improve the performance of a submersible pump. The blade inlet angle of a diffuser is the most important geometric parameter that affects the performance of a submersible pump. The present paper focused on the effects of different blade inlet angles of a diffuser on the performance of a submersible pump. Firstly, the theoretical analysis of the diffuser characteristic curve was carried out; Secondly, five sets of submersible pump models with different blade inlet angles and the same impeller were built and simulated. Finally, based on the obtained results, two characteristic parameters reflecting inlet and outlet velocity distributions in the diffuser were introduced, and the quantitative relationship between internal and external characteristics of the diffuser was established. It was found that as the blade inlet angle of the diffuser increased, the optimum operating point moved in the direction of large flow rate. When the blade inlet angle of the diffuser was in the range of 27°–30°, the efficiency of the submersible pump reached more than 75%, and the maximum change in the corresponding working flow was 0.2 times of the theoretical discharge. Furthermore, the values of the maximum speed reduction ratio ([Formula: see text], that is the ratio of inlet circumferential flow velocity to minimum flow velocity on the intermediate flow surface of a diffuser.) were located near 1.6, and they were positioned ([Formula: see text], that is the relative position of the lowest flow velocity on the intermediate flow surface along the flow path of the diffuser.) near the midpoint of the flow path of the diffuser. Moreover, with the increase in the change rate of different blade inlet angles ([Formula: see text]), the high-efficiency interval breadth ([Formula: see text], that is the relative rate of change in flow rate with respect to the highest flow rate at [Formula: see text].) manifested an increasing trend. When [Formula: see text] exceeded 0.06, the value of [Formula: see text] increased significantly, and the range of applicable flow intervals expanded simultaneously. According to performance requirements, the distribution of the internal flow field was specified to further enhance the adaptability of the submersible pump to different working conditions.

In the system solar power has been used for cultivation. Solar photovoltaic cells convert solar energy into electricity through solar photovoltaic (SPV) effect. Generated DC voltage then converted in to AC voltage by pump controller, this AC voltage is used as the input of Variable Frequency Drive (VFD). The VFD acts as a motor controller that controls the submersible pump motor by varying the frequency and voltage of its input power supply. The VFD is associated with pump controller. Regulated three phase AC voltage is the output of the pump controller which is directly connected with submersible pump. The water thus drawn from bore wells by a solar water pump is pumped to supply for irrigation purpose as required. This system is full off-grid interfaced system appropriate for the village areas. The main goal of this system is to use solar energy at a minimum running cost. The solar powered project is completely eco friendly and the plant is relatively clean with small maintenance. This project helps to reduce the cost of electricity, as well as minimize the overall agricultural cost.
