Speed ??is lower than 500r / min hydraulic motors are low speed hydraulic motor. Its basic form is a radial piston. The main features of the low-speed hydraulic motors are: large displacement pumps, large volume, low speed, you can connect directly with the work of agencies, no deceleration device, so that the transmission mechanism is greatly simplified, low-speed hydraulic motor output torque is large, up to several one thousand to tens of thousands Nm, so-called low speed high torque hydraulic motors. 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 plunger pump cam pushing domestic maintenance, piston and cylinder formation is reduced, the volume of oil out from the seal, the check valve routed to where it is needed. When the cam is rotated to drop site specializing in domestic pump curve, spring forces the piston down, a certain degree of vacuum, the oil tank into the sealed volume at atmospheric pressure. Cam constantly lift the plunger seal periodically decrease and increase the volume of the pump suction and discharge of oil have continued. Domestic pump maintenance, hydraulic pumps, hydraulic pressure from Jinan Jing Jing Chong Chong Hydraulic Machinery Limited. Jinan Jing Chong Hydraulic Machinery Co., Ltd.
