The paper considers the option to reduce power consumption in the operation of the underloaded trunk pipeline by engaging additional pump units with lower rotor r.p.m. control using variable frequency drive. Under these conditions, the operating point of the pumps (delivery rate, head) approaches to the rated output, thus increasing the efficiency of the pumps and decreasing the electricity power consumption for pumping operations. The paper presents comparative calculations of operating conditions for a section of the trunk pipeline with a specified pumping capacity of 35 million t/year (60 % of the design load) when one, two and three main line pumps with variable frequency drives are engaged. The power consumption for pumping is calculated using the dependence of the variable frequency drive and motor efficiencies on the electric motor load and rotational speed. Based on the results of calculations, the electric energy saving is determined when additional pumping units are engaged. The experience has shown that when the second main line pump was engaged, the electric energy saving for pumping was 3.7% compared to the condition with one pump running. However, if the third pump is engaged, the saving is only 1.9 % – the decrease is due to lower motor and variable frequency drive efficiencies in the underloaded condition.

Industrial heat pumps are heat-recovery systems that allow the temperature ofwaste-heat stream to be increased to a higher, more efficient temperature. Consequently, heat pumps can improve energy efficiency in industrial processes as well as energy savings when conventional passive-heat recovery is not possible. In this paper, possible ways of saving energy in the chemical industry are considered, the objective is to reduce the primary energy (such as coal) consumption of power plant. Particularly the thermodynamic analyses ofintegrating backpressure turbine ofa power plant with distillation units have been considered. Some practical examples such as conventional distillation unit and heat pump are used as a means of reducing primary energy consumption with tangible indications of energy savings. The heat pump distillation is operated via electrical power from the power plant. The exergy efficiency ofthe primary fuel is calculated for different operating range ofthe heat pump distillation. This is then compared with a conventional distillation unit that depends on saturated steam from a power plant as the source of energy. The results obtained show that heat pump distillation is an economic way to save energy if the temperaturedifference between the overhead and the bottom is small. Based on the result, the energy saved by the application of a heat pump distillation is improved compared to conventional distillation unit.

For the development of lowand medium-rate wells, the most commonly used installations are sucker-rod pumps. The group of sucker-rod pumps connected to the same power supply system is installed on the wells of one oilfield. The work of a sucker-rod pump is cyclical. Obviously, there is a relationship between the maximum power consumption of a group of cycle drives and the performance of this group. Selecting such a strategy for reducing the maximum power consumption, in which there will be no significant performance reduction, is an urgent problem. In this article, theoretical approaches are formulated for constructing the simulation model of a sucker-rod pump group as a group of cycle drives with unequal cycles. Several group control strategies that reduce the maximum value of power consumption are considered.

As the pump operates and wears out, the gap in the friction pairs increases and the volumetric efficiency decreases, the pump flow gets reduced, which leads to increasing duration of working and auxiliary operations, the operating cycle of the excavator, a decrease in its productivity and excessive fuel consumption. Infrequent pump replacement can lead to a significant increase in fuel consumption and reduced excavator performance. If the pump is replaced prematurely, its service life will not be used to the full extent. In order to develop a method for establishing optimal operating hours that allow minimizing fuel consumption and the cost of replacing a pump, taking into account operating conditions, a mathematical model of the pump operation is proposed, which makes it possible to obtain an expression for determining the differentiated optimal value of operating time between replacements. A calculation method and a software algorithm have been developed in the MatLab Simulink software suite to calculate the rate of decrease in the volumetric efficiency, as well as to establish the influence of volumetric efficiency on the fuel consumption and performance of a hydraulic excavator to be utilized in the model using the example of the HPV375 pump of the Komatsu PC2000-8 excavator, Based on the proposed mathematical model of the main pumps operation, a method has been developed for calculating the differentiated operating time between replacements of the main pumps of a mining hydraulic excavator, taking into account the rate of decrease in volumetric efficiency, replacement costs and damage due to changes in productivity and excessive fuel consumption. The dependence of the rate of changes in the volumetric efficiency of the pump is presented for the excavation, viscosity, contamination and temperature of the working fluid parameters. A coefficient of “reserve of partial engine power transferred to the pump” is proposed, determined by the ratio of the difference between the average maximum and initial partial power to the value of the initial partial power, which allows estimation of the operating time of the main pumps without affecting productivity of the excavator.

PDAM Surya Sembada Surabaya’s energy cost in 2021 amounted to Rp 147.654.439.569, with an energy cost ratio of 24.37%, and the electricity cost of production unit accounted for 76% of the total energy consumption of PDAM. The relatively flat topography does not allow gravity-based systems for water supply. Aging equipment has decreased overall pump efficiency (ηpt) and increased energy consumption, particularly in Ngagel I WTP, built in 1922, necessitating an energy audit. Energy audit includes measuring pump flow rate and pressure, power, voltage, current, power factor, pump and motor pump rotation and temperature. Analysis shows that raw water pumps U2, U3, U5, and S1 and distribution pumps U1, U3, and T4 are still in good condition. However, raw water pump U6 and distribution pumps U6, S1, and S2 require reconditioning and impeller adjustment due to declining efficiency. Furthermore, PDAM must inspect the distribution pump T1 with the lowest efficiency value (49.77%) to determine the appropriate repairs. The research results are action recommendations expected to serve as input and considerations for PDAM in their efforts to improve energy efficiency.

In an industry that uses large centrifugal pumps continuously, pump speed setting can reduce energy consumption significantly. By changing the speed of a centrifugal pump, capacity, head, and pump power required will change according to pump affinity laws. Speed of a centrifugal pump can be changed by variable frequency drive . This study aimed to investigate the characteristics of mixed flow centrifugal pumps with variable frequency drive. The results showed that 10% of maximum speed reduction can decrease power consumtion until 50%, while the increase in the efficiency is maximum 7.2%. The power reduction is different for different speed reduction. In a dynamic head dominated system the efficiency will remain constant during speed reduction while in static head dominated system will change.

Abstract Evaluation of carbon emission hot spots for water treatment plants (WTPs) is crucial to reduce carbon emissions. This study aims to analyze carbon emission data generated at Bansin WTP following the PAS 2050 guidelines. The boundary of inventory and assessment includes water intake, purification, and distribution stages. In addition, pumping efficiency, power consumption per pump lift and specific energy consumption were used to estimate the potential of energy reduction in pumping for Bansin and Baoshan WTPs. The results have revealed that the carbon footprint of Bansin WTP is 0.39 kg CO2e/m3 in 2011. There is 95% of carbon emissions generated by pumping from the intake and distribution stages, and the use of pumping is responsible for 65% of total carbon emissions in the clarification stage. The power consumption per pump lift can be calculated to evaluate the difference between rated power and operational power. This relationship can provide information indicating to operators when to replace or maintain poorly-functioning pumps. The data on pump lift, flow rate and power can also be calculated to determine the relationship between pumping efficiency (%) and specific energy consumption (kW/Q), and then used to identify the optimum condition of pump combinations for a given production of water supply.

Les pompes à anneau liquide sont des machines de compression volumétriques, principalement utilisées en pompe à vide et qui aspirent des gaz jusqu'à des pressions absolues de 30 mbar. Ces pompes possèdent de nombreux avantages mais un faible rendement global par rapport à l'isotherme qui peut descendre jusqu'à 10% et une consommation en eau importante. L'étude qui a été réalisée a permis d'améliorer ces deux derniers points. Apres une modélisation de la puissance absorbée par la méthode des pertes séparées, des axes de recherche ont pu être déterminés. Différentes solutions technologiques ont été testées sur un banc d'essais énergétique. Ce banc équipé d'une maquette de la série des pompes étudiées permet la mesure des caractéristiques de fonctionnement (pressions, débits, puissance, température) sur une large plage de pression et de vitesse de rotation. Une analyse dimensionnelle basée sur le modèle des turbomachines a permis de définir un jeu de coefficients sans dimensions permettant la transposition des résultats obtenus sur l'ensemble de la gamme des machines étudiées.

Abstract The objective of this thesis was to obtain new information about mechanisms of thermomechanical pulp refining in the inner area of a refiner disc gap by studying inter-fibre refining and by calculating the distribution of energy consumption in the refiner disc gap. The energy consumption of thermomechanical pulping process is very high although theoretically a small amount of energy is needed to create new fibre surfaces. Mechanisms of refining have been widely studied in order to understand the high energy consumption of the process, however, phenomena in the inner area of disc gap has had less attention. It is likely that this important position is causing high energy consumption due to the high residence time of pulp located there. The power distribution as a function of the refiner disc gap was calculated in this work. The calculation was based on mass and energy balances, as well as temperature and consistency profiles determined by mill trials. The power distribution was found to be dependent on segment geometry and the refining stage. However, in the first stage refiner with standard refiner segments, a notable amount of power was consumed in the inner area of the disc gap. Fibre-to-fibre refining is likely to be the most important mechanism in the inner area of disc gap from the point of view of energy consumption. In this work the inter-fibre refining was studied using equipment for shear and compression. Fibre-to-fibre refining was found to be an effective way to refine fibres from coarse pulp to separated, fibrillated and peeled fibres if frictional forces inside the compressed pulp were high enough. It was proposed that high energy of today’s thermomechanical pulping process could derive from too low frictional forces that heated pulp and evaporated water without any changes in fibre structure. The method to calculate power distribution and results of fibre-to-fibre refining experiments may give ideas for developing today’s thermomechanical pulp refiners’ or for developing totally new energy saving mechanical pulping processes.

Electro Hydrostatic Actuators (EHA) are emerging as a viable option for industrial machine builders as the design combines the best of both electro-mechanical and electro-hydraulic technologies. The EHA is a highly integrated, compact alternative to traditional hydraulic solutions. Automation engineers moving toward electro-mechanical actuation in pursuit of energy efficiency and environmental cleanliness, will find an EHA an attractive option for high force density actuators. This paper will address the factors to consider when assessing an industrial machine’s application suitability for this latest innovation in actuation. It describes principal base circuits, a concept for EHA building blocks and a realized pilot application as well as challenges on actuator and components level.

Resumo: O leite é um dos mais importantes produtos da agropecuária nacional, com cerca de 2/3 das propriedades rurais do país destinando-se à pecuária leiteira e com um dos maiores rebanhos do mundo. Apesar da grandiosidade, o setor ainda sofre com a baixa produtividade, os altos custos e a defasagem tecnológica. Como conseqüência, muitos produtores abandonaram suas atividades diante deste novo cenário competitivo. Atualmente, assuntos como uso racional de energia e aplicação intensiva de tecnologia tem sido intensamente discutidos e abordados, e indicados como aspectos importantes para a obtenção de ganhos de produtividade. Desta forma, visou-se neste trabalho avaliar o uso de energia no processamento de leite de três propriedades (leite pasteurizado tipo ¿A¿ e leite cru refrigerado), bem como, a representatividade dos diversos processos no consumo total, assunto este, ainda pouco conhecido e abordado no país. Objetivando ainda, promover a racionalização energética, avaliaram-se os potenciais de aproveitamento de calor de condensação de sistemas de refrigeração existentes para o aquecimento de água de limpeza e higienização, bem como, avaliou-se a viabilidade técnica e econômica da adequação dos sistemas (operação segundo um bomba de calor com geração simultânea de duas fontes térmicas) em substituição ao uso de resistências elétricas. Dentre as proposta, avaliou-se a adequação realizada em um planta piloto em operação. Com o uso de bomba de calor, a redução no consumo total de energia elétrica foi de até 15% com tempos de retorno dos investimentos variando entre 1,3 e 3,7 anos
Abstract: Milk is one of the most important products of Brazilian agriculture, with about 2/3 of the rural properties dedicated to the milkmaid cattle breeding and with one of the largest flocks of the world. In spite of its size, the sector still suffers of low productivity, high costs and tecnological delay. As a consequence, many producers have abandoned its activities before this new competitive technology were introduced. Now, subjects as, the use rational of energy and intensive application of technology has been discussed intensely resulting in productivity gains. In this work , it was seek to evaluate the use of energy for milk processing in three different properties (pasteurized milk type " A " and refrigerated raw milk). It was also evaluated how representativive the several processes in the total consumption were, a problem, still not very well-known and trated in Brazil. To promote the energy rationalization, the potential use of condensation heat of refrigeration systems was evaluated for the cleaning water heating, as well as, the technical and economic viability of the adaptation of the systems was evaluated (operation according to a heat pump with simultaneous generation of cold and heat) in substitution to the use of electric resistances. In the midst of proposals, an adaptation was evaluated in a pilot plant in operation. With the use of heat pumps, there was a decreasing of 15% in the consumption of eletric energy with payback between 1,3 and 3,7 years

According to the World Health Organization (WHO) report, cardiovascular disease is one of the top 10 causes of deaths today, in which heart disease is the first death rate, so how effective treatment of heart disease has become an important issue. The development of left ventricular assist device (LVAD) plays a key role in clinical treatment and improves the survival rate of patients with severe heart disease. And compared to the widely used continuous left ventricular aids, pulsating can pulsating the way to promote blood, this method is closer to the heart of the movement, help to restore cardiac function. However, pulsating pumps in the process of promoting the blood to consume higher power, but also make the pump heat, causing inconvenience. This study will refer to the pulse width modulation (Pulse Width Modulation, PWM) method, for the team developed by the 24-coil magnetic drive pump to observe and find low-power drive. The pump will interact with the magnetic field formed by the energization of the coil and interact with the permanent magnets placed in the pump internal piston, thereby driving the piston to reciprocate and use the Hall sensor to monitor the piston position in real time, The drive signal remains the same. Experimental results show that, according to the design of the drive method, can reduce the power loss of 40%, to achieve the purpose of energy conservation.

As South Africa's electricity consumption increases, Eskom is promoting Demand Side Management (DSM) to aid control of both the electricity consumption and its more effective usage, thereby delaying the need to construct new power stations, which pose large economic and environmental problems. Eskom has investigated various DSM strategies, such as load shifting, co-generation, alternative fuels and energy efficient processes, and has targeted the areas of load shifting and energy efficiency as prime areas for energy savings as they are relatively inexpensive and easy to implement. Pumps and fans form a large part of the industrial load. By improving the power usage of these devices with the use of variable speed drives, large energy savings may be achieved. To enable the energy usage of industrial loads to be evaluated, a test bed system which enables a variable speed drive to be loaded with a configurable load, was constructed. The test bed system forms a tool for evaluating and demonstrating the energy savings that are possible, by replacing fixed speed drives with variable speed drives when controlling the flow rate of pumps and fans. Results from the test bed system show that by using variable speed operation of pumps and fans, some energy savings are achievable when compared to existing methods of flow control. The achievable energy savings are dependent on the system properties and the duty cycle of the pump or fan system.

AbstractHydraulic pump is a product with high reliability and long-life, there exist many urgent problems like long test period, high cost and a larger power consumption in the reliability evaluation method of pump. A new kind of reliability test bench is built combined with parallel power-saving design concept, which based on principles of energy saving and power recycle. Multi-pumps reliability accelerated degradation test is achieved by applying step stress on the pump under test. Volumetric efficiency is selected as performance degradation evaluating index, the degradation of whose is much closed to real physics model. The accretion model for hydraulic pump reliability test is built based on inverse moment estimation method, by which hydraulic pump reliability level under different stress conditions is given. In the meantime, the method of concurrent accelerated degradation testing can serve as references of other core hydraulic components.

AbstractParticularly during grinding of metal workpieces, a high energy consumption is required during the main process times, so that the resulting energy costs represent a significant amount of the total operating costs of the machine tool. In this context, the supply of metal working fluids (MWF) during the grinding process is often associated with a high energy consumption, but the MWF supply strategy (MWF flow rate, MWF nozzle, control and dimensioning of the MWF supply pumps) can significantly influence the energy efficiency of such processes. In the scope of this work, additive manufacturing was used to produce fluid supply nozzles adapted to the respective grinding process. In this work, it was shown that by using a flow-optimized nozzle the required power of the MWF supply pump can be significantly reduced, allowing to make the grinding process more efficient in terms of the energy required.

AbstractWhen the loader boom is lifted and lowered, the hydraulic pump operates at high peak power levels. In this process, the hydraulic valve port dissipates the gravitational potential energy of the boom. Consequently, the dissipated energy is converted into thermal energy, resulting in elevated hydraulic oil temperature and reduced energy efficiency. This paper proposes a gravitational potential energy recovery system based on three-chamber cylinder and a hydraulic accumulator. The system utilizes the hydraulic accumulator to balance the weight of the loading boom and achieve energy recovery for the boom. The co-simulation model of wheel loader based on the three-chamber cylinder was built in SimulationX, then the energy consumption was analyzed under two kinds of typical operating modes. The simulation results illustrate that when the initial pressures of accumulators are 6 and 8 MPa with heavy-load and without load, the system has the highest energy utilization rate. By establishing a loader prototype and investigating the operating characteristics and energy efficiency of the boom driven by a two-chamber cylinder and a three-chamber cylinder, the experimental results illustrate that the new system operates smoothly, reducing energy consumption by 39.24% and peak power by 27.41%.

AbstractThis study consists of a sensitivity analysis of photovoltaic/thermal (PV/T) collectors, liquid thermal storage, and battery systems applied for the offices of a school building near Montreal, Canada to enhance building performance and resiliency to power outages during winter operation. The analysis was applied for 3 days in January with mixed solar conditions by varying the sizing of each of the components to achieve at least 8 h of self-sufficiency, the average length of power outages. It was found the optimal sizing for the studied system, while minimizing component costs, is to dimensions PV/T collectors to meet the base heating load, while maximizing thermal storage, and diminishing battery capacity to meet the base heat pump electricity consumption. For the case study, the optimal configuration was 27 PV/T, a 908 L thermal storage tank, and 10 kWh of battery capacity, to consistently achieve over 8 h of self-sufficiency in mixed sunny and cloudy winter conditions.

AbstractWith the pressure to transition towards a fully renewable energy system increasing, a new type of power system architecture is emerging: the microgrid. A microgrid integrates a multitude of decentralised renewable energy technologies using smart energy management systems, in order to efficiently balance the local production and consumption of renewable energy, resulting in a high degree of flexibility and resilience. Generally, the performance of a microgrid increases with the number of technologies present, although it remains difficult to create a fully autonomous microgrid within economic reason (de Graaf F, New strategies for smart integrated decentralised energy systems, 2018). In order to improve the self-sufficiency and flexibility of these microgrids, this research proposes integrating a neighbourhood microgrid with an urban agriculture facility that houses a decoupled multi-loop aquaponics facility. This new concept is called Smarthood, where all Food–Water–Energy flows are circularly connected. In doing so, the performance of the microgrid greatly improves, due to the high flexibility present within the thermal mass, pumps and lighting systems. As a result, it is possible to achieve 95.38% power and 100% heat self-sufficiency. This result is promising, as it could pave the way towards realising these fully circular, decentralised Food–Water–Energy systems.

AbstractThis paper focuses on process chains for power train components of passenger cars and heavy duty vehicles. In the project “Powertrain 2025” particular attention is being paid to increase the resource efficiency of the manufacturing process chains and reduce energy demand during service life. In detail cylinder liners are equipped with an adapted geometry and topography which reduces friction losses. Process chains for chassis components are investigated and optimized in order to increase the resource efficiency during manufacturing, service life and maintenance. In addition, process chains for the manufacturing of drive shafts are adjusted. By eliminating hard machining, energy is saved and friction losses are reduced by laser machining of microstructures. Furthermore, micro dimples are applied in vane pumps, which leads to a tribological improvement and thus enhances their friction behaviour. Moreover, a system architecture for process planning is developed and ecologically optimized process parameters are calculated. For a final consideration, a calculation software is developed which enables to calculate the main energy consumption of the manufacturing processes and the carbon footprint for the expected service life. A weight reduction of the powertrain components of 4.5 kg per vehicle and a potential annual energy saving of 13,073 MWh is obtained.

Fluidic driving device plays an important role in the delivery and distribution of minute amount of the liquid in the micro-fluidic system. Due to the unique advantages of simple structure, short response time, and low power consumption, piezoelectric actuation was employed to implement the microfluidic transportation. A piezoelectrically driven microfluidic device, piezoelectric pump, was developed and widely applied in many fields in last three decades. As a kind of displacement pump, piezoelectric pumps is able to realize accurate transportation of the liquid because of per stroke of output fluid is equal to the volumetric change of pumping chamber. And the output flow rate and pressure is easily to be controlled through adjusting the driving voltage or frequency. In this chapter, the design, structure, working principle and the characterisation of piezoelectric pumps with single chamber and multiple chambers are introduced.

In a Nuclear Power reactor, safety loads are backed by standby battery system. The healthiness of the battery is very essential requirement and prominent attention is given to availability and reliability of battery supply in nuclear plants. Hence regular monitoring and testing the performance of the battery is a prime requirement. The capacity and load cycle discharge testing of the battery is done annually and the current system employed is to discharge the battery current through resistor banks, which results in unusable power consumption and is uneconomical. The growing trend in power electronics field has given the new technology of regenerating the dissipated power to grid. This paper proposes a high power electronic regenerative technology with high efficiency, low harmonics to pump the dc power to the grid. Though, it is available at lower rating in industry, the paper proposes a high power regenerative discharge system. The topology selected is interleaved boost converter interfaced to a three phase grid connected inverter. The challenges involved are high power operation, steep current discharges with a minimal interference to the normal plant operation power supplies during the regeneration. This paper also presents the system design and simulation results.

Gear pumps are used in numerous different applications and industrial sectors. However, when selecting a suitable gear pump for a specified application, manufacturers are often confronted with a lack of comparable measurement data for the desired combination of operating conditions and pumping fluid. Consequently, an estimation of the volume flow rate and the power consumption of a pump under the operating conditions of the application is necessary. In this context, this paper discusses the application of similarity on external gear pumps and presents its validation by means of measured pump characteristics. Seven gear pumps of different displacement volume are measured at different operating conditions varying pressure, rotational speed and the viscosity of the pumping fluid. The validation results prove that similarity is useful to represent a pump’s characteristic over a wide operating range. The prediction of the volume flow rate and the power consumption at a changed viscosity show good accuracy. However, the scaling of the pump characteristic based on the displacement volume show contradictory results.

Wood chips are the primary sources of raw materials for numerous industries, including pelleting mills, biorefineries, pulp-and-paper industries, and biomass-based power generation facilities. Unfortunately, when wood chips are utilized as a renewable and environmentally friendly resource, industries are constantly challenged by the consistency of the wood chip qualities (e.g., moisture/ash contents, size distributions) - a historically recognized problem on a global scale. Among other wood chip quality attributes, the moisture content is considered the most pressing one as it directly impacts the energy content, storage stability, and handling properties of the raw and finished products. Therefore, accurate wood chip moisture content prediction can help optimize the drying process and reduce energy consumption. In this review, a survey was conducted on various techniques and models employed for predicting wood chip moisture content. The advantages and limitations of these approaches, as well as their potential applications and future directions were also discussed. This review aims to provide a comprehensive overview of the current state-of-the-art in wood chip moisture content prediction and to highlight the challenges and opportunities for further research and development in this field.
