A hydraulic pump station is a hydraulic source device that provides power to hydraulic systems. Currently, there are two commonly used pumps in hydraulic pump stations: quantitative pumps and variable displacement pumps. The displacement of the quantitative pump cannot be changed. The flow provided to the hydraulic system during use is regulated by the speed control valve or throttle valve, and the excess flow flows back to the oil tank through the overflow valve, resulting in significant energy waste; Variable displacement pumps have variable displacement, with variable displacement piston pumps being the main type. However, variable displacement piston pumps have complex structures, require large processing equipment investment, are expensive, and have high noise levels and long supply cycles. They are mainly used in high-end hydraulic systems. Due to the low efficiency and serious energy waste of traditional hydraulic pump stations, in-depth research on efficient, intelligent, and energy-saving new hydraulic pump stations has great theoretical significance and practical value for promoting economic development and energy conservation.
