Hydraulic pump to provide pressurized fluid to a hydraulic device for hydraulic transmission, is a pump. Its function is to power machine (such as a motor and an internal combustion engine, etc.) of the mechanical energy into pressure energy of the liquid. Single-piston pump works cam is rotated by the motor, sealed volume when the upward movement of the cam push the plunger hydraulic motors domestic maintenance, reduced piston and cylinder formation, oil squeezed out of the sealed volume through check valve routed to where it is needed. When the cam portion is rotated to decrease the hydraulic motor curve domestic maintenance, the spring forces the plunger downwardly, a certain degree of vacuum, the oil tank into the sealed volume under the effect of atmospheric pressure. Cam constantly lift the plunger seal periodically decrease and increase the volume of the pump suction and discharge of oil have continued. The maximum speed of the hydraulic motor speed is mainly affected by the use of life and mechanical efficiency of the hydraulic motor to limit domestic refinement, after the speed increase, deputy movements increased wear life lower, high speed hydraulic motor is required to enter the traffic on the large, Therefore, the flow rate of each flow part of the corresponding increase in the pressure loss also increases, so that the mechanical efficiency. Domestic hydraulic motor maintenance, crystal creating hydraulic (certified), hydraulic motors provided by Jinan Jing Chong Hydraulic Machinery Co., Ltd ..
