Abstract:An introduction to the structure and main function of a movable hydraulic pumping station is presented,together with a discussion of the hydraulic system′s design principle and working process.Based on the analysis of pumping station′s driving system,the main performance parameter choice of hydraulic motor,hydraulic pump,and internal combustion engine is given.It is found that the input power of each element is proportional to the cubic of the speed of rotation.These results provide important reference values in designing the movable hydraulic pumping station.movable hydraulic pumping station;hydraulic system;driving system;internal combustion engine;parameter choice
