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.

When the pressure of an oil well is not too large to do Natural Flow, Artificial Lift is one of the methods that can be used to replace it, artificial lift usually using ESP (Electric Submersible Pump). ESP oil pump in petroleum is equipped with VSD (Variable Speed Drive) component to adjust motor speed as softstarter and oil rate regulator and as pump motor protection. For ESP construction with a motor tandem system installed on wells with different characteristics and depths that are different from ESP single motors. However, submersible pumps are augmented by increasing the number of pump stages according to the depth of the well by coupling, submersible electric motors can be mechanically coupled and electrically on a spindle between upper motor and center motor.

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.

Due to the increasing demand, nonclog type sewage pumps are designed and manufactured in large amounts all over the world. However, a methodology on the design of these special duty pumps is not encountered in the literature. Therefore, the manufacturers tend to develop their own empirical methodologies. In this thesis, a nonclog pump is designed and constructed on the basis of suitable approaches of known centrifugal pump design methods. In this frame, a nonclog type submersible pump that is capable of handling solids, up to a diameter of 80 mm is aimed to be designed. The designed pump delivers 100 l/s flow rate against a head of 24 m. The rotational speed of the pump is 1000 rpm. Design procedure and the important points that differ nonclog pump design from standard centrifugal pump designs are given. In addition, hydraulic characteristics of two nonclog pumps, one of which is the pump designed in this study, are investigated by means of computational fluid dynamics (CFD) code. The designed pump is manufactured and tested in Layne Bowler Pump Company Inc. The test result indicates that design point is reached with a deviation in the limits of the related standard. Wire to water total best efficiency obtained by the test is 60%. Close agreement between results of actual test and numerical experimentation performed by CFD code shows that CFD analysis is a quite useful tool in predicting the hydraulic characteristics of nonclog pumps. Moreover, the pump is tested at 750 rpm and the test results are found to be in good agreement with the similitude anaysis results.

There are some alternatives of artificial lift methods to increase the production of oil well or to keep it producing. Sucker rod pumping (SRP) and electrical submersible pumping (ESP) systems are selected for the design and economical evaluation of thirteen oil wells of R field. Although selected wells are already producing artificially, they are redesigned for SRP and ESP. LoadCalC software developed by Lufkin and SubPUMP developed by DSSC are used for SRP and ESP designs respectively. For economic evaluation, the rate of return (ROR) of each design is calculated for ten year period. In technical comparison, advantage of higher production ability with lower power consumption was observed in ESP applications. In wells which have lower production than 100 bpd, SRP takes the advantage as it has the ability of low volume lifting. In economical comparison it was observed that using both methods together was given better result. By increasing the number of wells that were applied ESP, 3.61% of increment in ROR was obtained relative to the present status.

Resumo: Na indústria do petróleo é comum à utilização de bombas centrífugas submersas (BCS) operando em escoamento multifásico líquido-gás. A presença de elevadas vazões de gás causam uma degradação severa no desempenho da bomba, gerando instabilidades nas curvas de pressão-vazão, como o `surging¿ e o `gas locking¿. Portanto o conhecimento destas instabilidades é fundamental para a adequada operação da bomba e assim evitar falhas prematuras no equipamento. Na atualidade não existem modelos matemáticos que representem de forma adequada o comportamento da BCS na região de `surging¿ e no `gas locking¿, gerando a necessidade de empregar circuitos de testes para fazer o levantamento das curvas de desempenho das bombas. A maioria dos circuitos de testes é operada de forma manual para obter às condições de operação da bomba, tornando os ensaios repetitivos, cansativos e trabalhosos. Por isto nasce a necessidade de automatizar estas bancadas com a finalidade de facilitar o processo do levantamento das curvas de desempenho das bombas. Este trabalho apresenta o projeto e simulação de um controle robusto tipo H_? que permita manter o escoamento multifásico na entrada de uma BCS em diferentes condições de operação da bomba. Este controlador é projetado a partir de um circuito de testes para BCS virtual que é modelado empregando formulações físicas e modelos ajustados mediante dados experimentais usando algoritmos de aprendizagem de máquinas baseados em máquinas de suporte vetorial para regressão (SVMr). Após o projeto de controle, o controlador projetado é testado no circuito de testes virtual mediante simulações em tempo real `software in the loop¿ (SIL)
Abstract: In the oil industry, it is common to use electrical submersible pumps (ESP) operating with gas -liquid multiphase flow. The presence of high gas flows cause severe degradation in performance of the pump, generating instabilities in the flow-pressure curves, as "surging" and "gas locking". Therefore knowledge of these instabilities is essential for the proper functioning of the pump and thereby prevents premature failure of the equipment. Currently there are no mathematical models that adequately represent the behavior of the EPS in the region of "surging" and "gas locking", creating the need to use test circuits to make a study of the performance curves of the pumps. Most test circuits are operated manually to reach the operating conditions of the pump, making repetitive, tedious and laborious trials. Therefore there is a need to automate these circuits in order to facilitate the process of obtaining the performance curve of the pump. In this paper the project and simulation of a robust control type H_? for keeping the multiphase flow in the entrance of a EPS operating at different conditions is performed. This controller is designed based on a test circuit virtual for EPS which is modeled using physical formulations and adjusted models obtained by experimental data using machine learning algorithms based on support vector machines for regression (SVMR). After the controller design, the control is tested in the virtual test circuits using simulations in real time "software in the loop" (SIL)

Resumo: Neste trabalho foi desenvolvido um modelo para determinação da temperatura do motor de uma bomba centrífuga submersa (BCS) sob condições variáveis de vazão e carga. Este leva em consideração o comportamento acoplado entre o motor, a bomba e o sistema de produção. Assim, dada uma frequência ajustada no variador de frequência, a temperatura do motor é determinada como resultado do equilíbrio entre a produção de calor, calculada a partir da potência que a bomba demanda do motor, e a extração do calor, calculada a partir da vazão. Neste modelo, considera-se a BCS instalada num módulo de bombeamento submarino localizado perto do poço produtor. Foi estudada a transferência de calor por convecção no módulo de bombeio, onde um escoamento descendente ocorre no anular externo entre o revestimento e a camisa de refrigeração e um fluxo ascendente ocorre no anular interno entre a camisa de refrigeração e o motor. Um estudo de transferência de calor por convecção foi elaborado comparando modelos baseados no perfil de temperatura plenamente desenvolvido com modelos que consideram o desenvolvimento da camada limite térmica. Uma vez que o único ponto de medição da temperatura se localiza na extremidade inferior do enrolamento de estator, o modelo desenvolvido neste trabalho também determina a distribuição de temperatura do motor. Um estudo de caso foi realizado com diversas viscosidades de óleo e frações de água. Os resultados mostram a elevação da temperatura do motor, quando sua velocidade é continuamente aumentada. Também se mostrou que, negligenciar os efeitos do desenvolvimento da camada limite térmica, quando ocorre escoamento laminar, pode resultar num motor superaquecido, onde na verdade, a temperatura máxima do motor é muito menor do que o seu limite superior. Modelos baseados no perfil temperatura plenamente desenvolvidos sofrem de imprecisão, quando utilizados em aplicações de fluidos viscosos, devido ao grande comprimento entrada térmica
Abstract: A model to predict the motor temperature of an electrical submersible pump, under variable conditions of flow rate and loading, has been developed. This model takes into account the coupled behavior between motor, pump and production system. Thus, given a frequency set in the variable speed drive, the motor temperature is determined as a result of the equilibrium between the heat generation, calculated from the power that the pump demands from the motor, and the heat extraction, calculated from the flow rate. In this model, the electrical submersible pump is supposed to be installed in a subsea pumping module located near the producer well. It has been studied the convective heat transfer in the pumping module, where a downward flow occurs in the external annulus between the casing and the shroud, and an upward flow happens in the internal annulus between the shroud and the motor. A convective heat transfer study has been run comparing models based on fully developed temperature profile and models that consider the development of the thermal boundary layer. Since the only point of temperature measurement is located at the lower end of the stator winding, the model developed in this work also determines the temperature distribution of the motor. A case study has been run with several oil viscosities and water cut. The results show a motor temperature rise when motor speed is continuously increased. It is also showed that, when laminar flow occurs, neglecting the effect of the thermal boundary layer development may result in an overheated motor prediction where actually, motor maximum temperature is much smaller than its upper limit. Fully developed temperature profile models suffer of inaccuracy when used in viscous fluid applications, due to its big thermal entry length

Resumo: Este trabalho tem como objetivo desenvolver um processo de identificação da vazão de gás em um dos equipamentos usados na indústria petrolífera, às bombas centrífugas submersas (BCS) em regime de escoamento multifásico. Estas bombas apresentam falhas frequentes prematuras quando a vazão de gás é alta, as quais ocorrem por falta de informação do tipo de escoamento bifásico presente na bomba no tempo de operação. Por isto estudos de identificação experimental são requeridos nesta área. Neste contexto a presente pesquisa tem seu foco na obtenção de modelos mediante dados experimentais, recompilados diretamente da resposta do sistema que descrevem o comportamento da vazão de gás na planta de interesse, como: vibração, vazão, elevação entre outros. Estes modelos estão baseados na identificação não paramétrica e no algoritmo de aprendizagem de Máquina de Vetores de Suporte (SVM), onde os parâmetros ocultos da máquina de aprendizagem serão obtidos mediante algoritmos genéticos, visando obter modelos mais representativos
Abstract: This work develops a process to identify the flow of gas in one of the equipment used in the oil industry, the electric submersible pump (EPS) under multiphase flow. These pumps feature frequent premature failures when the gas flow is high. That occurs due to lack of information on the type of two ¿ phase flow in the pump in operation time. Experimental studies for this identification are required in this area. In this context, the present research focuses on obtaining models by experimental data collected directly from the system response which describes the behavior of the gas flow on the system of interest such as: vibration, fluid, elevation etc. These models are based on nonparametric identification and in learning algorithm support vector machine (SVM), where the hidden parameters of the learning machine will be obtained by genetic algorithms in order to obtain more representative models

Анотація:
У дисертаційній роботі подане нове вирішення наукової задачі, що полягає в удосконаленні конструкції герметичного моноблочного насосу з порожнистим валом на основі результатів наукових досліджень впливу особливостей конструкції підвідного пристрою на течію та енергетичні процеси в проточній частині насоса і елементах електродвигуна. Розроблено конструкцію герметичного відцентрового моноблочного насоса. Шляхом аналітичного дослідження комплексу факторів навантаження ротора (ваги, гідродинамічних та магнітних сил) визначено їх взаємний вплив та взаємозв’язок з робочим процесом підшипників ковзання Проведення числового моделювання дало можливість оцінити структуру потоку у проточній частині насоса, а саме вплив ОПП з обертовими стінками та дифузором перед входом в РК, на структуру потоку на вході в РК, параметри розподілення складових абсолютної швидкості та протікання кавітаційних процесів в ОПП та РК. Визначено діапазон оптимальних величин діаметрів ОПП з точки зору мінімальних гідравлічних втрат в ОПП та електричних втрат в роторних магнітопроводах електродвигуна за умови порожнистого валу насоса з коефіцієнтом швидкохідності (ns) в діапазоні від 60 до 70. Встановлено що перші прояви кавітації спостерігаються в РК, зменшення діаметру ОПП призводить до зміни місця виникнення кавітації і напрямку її розповсюдження. Розроблені методичні рекомендації щодо проектування герметичних моноблочних насосів з порожнистим валом та врахування впливу геометричних параметрів ОПП на конструктивні особливості вхідної частини лопатей РК. Експериментально підтверджено результати, які отримано числовим моделюванням.
The work is focused on the pump construction, which ensures high performance correlated with the safety aspects. It leads to the application of the pump, where the likelihood of the failure of the unit is minimal. The double entry pumps are commonly used due to the reduction of the hydraulic forces and also hermetic units, with closed, seal-less construction. The thesis presents a new solution to the scientific problem, which focuses on the improvement of the design of a sealless double entry close coupled centrifugal pump with a hollow shaft. In this conception, the inside of the hollow shaft is an axial inlet device, which consists of a straight part and diffuser. The design of a sealless close coupled centrifugal pump has been developed. Conducted analyses are based on the results of the investigation of the influence of axial inlet device geometrical features on pump working process in order to achieve minimal energy losses in the flowing part of the pump. The mutual influence of the construction of plain bearings and forces acting on the motion elements of the pump was elaborated. The rotating parts are loaded with the hydrodynamic, magnetic and gravity forces, which are the preliminary design data of bearing. On the other hand, the construction of bearing is severely acting on the mentioned above forces, which leads to the crucial design problem. Conducted numerical simulations made it possible to estimate the flow structure in the flowing part of the pump. In detail, the influence of the axial inlet device with rotating walls and the diffuser before the impeller inlet on the performance of the pump was recognized. The range of optimum values of axial inlet device diameters is also determined in terms of minimum hydraulic losses in the axial inlet device and electric losses in the rotor magnetic circuits of the motor under the condition of a hollow pump shaft with specific speed (ns) in the range from 60 to 70. Moreover, the flow structure at the impeller inlet, the parameters of the distribution of the absolute velocity components and the cavitation processes in the axial inlet device and the impeller were investigated. It is established that the first appearance of the cavitation was observed in the impeller. The reduction of the axial inlet device diameter leads to the change in the locations of the cavitation zones and the direction of their distribution. The methodical recommendations for the design of sealless close-coupled pump with a hollow shaft and the influence of the geometric parameters of the axial inlet device on the structural features of the leading edge of the blades of the impeller were developed. The results obtained by the numerical simulation were experimentally confirmed.
