HST hydraulic CVT has the following advantages: 1) the current closed system variable pump are integrated structure, charge pump and fill oil spills, control and other functions integrated on the hydraulic valve, pipe connections make it easy , not only reduces the installation space of the hydraulic motor installation and reduces the leakage and pipe vibration caused by a pipeline connection, improve system reliability and simplify the procedure. Cavitation repair hydraulic (2) charge system not only ensures the main pump displacement is changed in response to displacement drive to improve the operating frequency of the system, but also increase the main pump pressure at the inlet to prevent large volume motor, can effectively improve the speed of the pump and prevent pump cavitation hydraulic motor repair, improve work life; fill the oil system equipped with a filter, to improve the reliability and service life of the actuator; in addition, the charge pump also convenient for a number of low-voltage auxiliary power agencies. (3) Since only a small amount of oil drawn from the tank, reducing the loss of the fuel tank. Driven reciprocating plunger hydraulic motor with oil pan, the plunger is a small cylinder reciprocating piston pump make the suction pump oil movement is relative sliding of the plunger and plunger sleeve to change the volume to achieve the suction and discharge of oil, tail has two one-way valve between the plug and the sleeve by viscosity and oil to seal the gap. Piston axial piston pumps and radial piston pumps. Piston axial piston pumps and radial piston pumps. Repair of hydraulic motors, hydraulic motors, hydraulic pressure from Jinan Jing Jing Chong Chong Hydraulic Machinery Limited. Jinan Jing Chong Hydraulic Machinery Co., Ltd.
