With scientific and technological development, hydraulic technology in the gross national product was widely used, has become a modern transmission and control one of the key technologies, which use hydraulic complete energy transfer process. Because the hydraulic control flexibility and convenience, hydraulic control in industry wide attention. Hydraulic drive to examine pressure fluid medium for energy to achieve the various machinery and automatic control subjects. Hydraulic drive to the use of such components required for the composition of the control loop, Several circuit by becoming an organic combination of the completion of certain transmission system control functions to complete energy transfer, conversion and control. Response time was the design, I design, "a high pressure pump-valve-cylinder non-recovery of integrated power detection device design" This system can detect pump, valve, cylinder and the basic performance indicators can do right cylinder Test. The design, has done a system design, system components to the selection of non-standard pieces of the structure design, performance calculation, complete brochure, mapping and other tasks.
