(1) The roller hydraulic motor output torque is not enough. The roller outer circle is parallel with the housing hole, or the pressure oil leakage of the oil cavity (out of the oil cavity) after using wear, and the amount of leakage is increased, and should be re-processed by brushing or re-processing. Roller is equipped.
Under the premise of the main circuit safety valve, overload valve and other attachments, the intake pipe and hydraulic motor interface will be sealed (not allowed to leak), and the maximum pressure of the oil supply oil is measured at the motor, reverse rotation; then turn on the motor The pipe is determined when there is a load-bearing pressure; finally, the measured value can be determined to determine the fault portion with its technical requirements.
Piston motor is mainly composed of connecting rod, crankshaft, piston, cylinder, body, valve, etc. Compressed air is supplied to each cylinder in turn through the air distribution valve, so as to expand and do work, and push the crankshaft to rotate through the connecting rod. The work mainly comes from the gas expansion work.
To reduce the pressure energy loss of the hydraulic motor in the hydraulic system, we must first start from the inside, and reduce the power loss while reducing the internal pressure loss of the system.
Hydraulic motors and hydraulic pumps are the two most important heat sources in hydraulic systems.
The hydraulic motor, like the hydraulic pump, relies on the change of the sealed working volume to achieve energy conversion, and also has a flow distribution mechanism.
