Common Problems Of Hydraulic Press

1 hydraulic pump plunger pump heating. This is because the pump plunger and the cylinder hole, valve plate and cylinder combination between wear and tear caused by internal leakage increases, leakage of hydraulic energy into heat caused by fever.
2 hydraulic oil temperature is too high. Is the most common problem, high pressure oil liquid viscosity friction will be large, hydraulic friction heat cause the temperature. High temperature will affect the normal work.
3 motor burned. Hydraulic machine in the process of the work will also appear the problem of burning motor. This problem is due to the circuit connection is not connected, the problem should first check the circuit.
