Check the motor steering; replace the pump or key; clean and repair the relief valve; replace the spring; clean, repair or replace; check the condition of wearing parts in the pump, cylinder, and valve and the sealing of each connection in the system.
The flow rate of the variable pump is improperly adjusted—readjust to the required flow rate. The pressure of the oil pump (hydraulic pump) cannot rise. The oil pump is not oiled or the flow rate is insufficient—Same as the above troubleshooting method. The adjustment pressure of the relief valve is too low or malfunctions—Re-adjust the pressure of the relief valve or repair the relief valve.
Cause of failure: The hydraulic oil is too dirty. Troubleshooting method: Clean the system and replace the hydraulic oil.
As for the maintenance of the hydraulic oil pump, it is not difficult. Here is a simple and practical method: rough grinding. Place the 120# coarse emery cloth on the flat glass, add a little engine oil and 80 mesh abrasive sand, and then place the oil distribution plate flat on the emery cloth for smooth grinding. The technique of flat grinding is: grind while turning, the trajectory is in the shape of “8”.
Hydraulic pump maintenance method Hydraulic pump oil supply form–the straight-axis swash plate plunger pump has two oil supply forms, namely pressure oil supply and self-priming oil. Pressure supply hydraulic pumps generally use a gas tank with air pressure. Some hydraulic pumps themselves have an oil supply sub-pump to provide pressure oil to the oil inlet of the hydraulic pump.
