Energy Loss Analysis of External Gear Pump

Due to the fact that 60% of the input power of a typical hydraulic system is converted into heat energy and consumed, modern hydraulic systems prioritize improving system efficiency and reducing energy consumption as important quality indicators. The transmission efficiency of hydraulic systems is relatively low, and in the past, people often only focused on the indicators of their control and regulation performance, without clearly considering system efficiency as one of the goals, resulting in a large amount of energy waste. The reactive power of hydraulic systems will also be converted into heat, affecting the life and performance of components and accelerating oil aging. In order to improve the efficiency of the pump, it is necessary to analyze the energy loss of the pump. The efficiency of a gear pump is an important indicator for measuring the economic efficiency of its operation.
