Common symptoms of a hydraulic axial piston pump have? Less (1) hydraulic pump discharge of oil hydraulic motors, actuators slow movements. (2) insufficient hydraulic pressure or pressure pulsation larger repairs hydraulic motors, actuators weakness. (3) hydraulic pump operation noise is too large. (4) an external pump hydraulic oil leakage. (5) hydraulic pump heat. (6) The variable mechanism failure. (7) double axial piston pump PV can not rotate. (8) hydraulic oil temperature is too high. In a hydraulic system with a directional axial piston pump drives a motor, rated working pressure 200bar, pump speed requirements of the motor Maximum speed 540rpm 1800rpm maximum output torque 320N.m reasonable matching namely displacement pump and motor specifications. Rounding value can be, is not necessarily the same specifications, the hydraulic motor is mounted, without regard to efficiency. (Shaft torque = displacement * Pressure / 20π) NOTE: In a hydraulic system with a directional axial piston pump motor drives a hydraulic motor repair, rated working pressure of 200bar, the pump speed 1800rpm maximum speed of 540rpm motor requirements The maximum output torque 320N.m reasonable matching namely displacement pump and motor specifications. Rounding value can be, it is not necessarily the same specifications, without regard to efficiency. (Shaft torque = displacement * Pressure / 20π) hydraulic motor hydraulic motor sales _ _ creating a hydraulic factory direct crystal grain from Jinan Chong Hydraulic Machinery Limited.
