Failure Analysis Caused by Downstream Pressure of Four Pillar Hydraulic Press

Failure problem one: support pressure is too large

The solution is to adjust the pilot valve to bring it under pressure in a certain range, so that support pressure will not be too large.
Problem two: After parking, the slider fell seriously
The reason, it may be bad seal performance, there is leakage phenomenon. At this time, it should be replaced.
Problem three: the pressure gauge pointer swing amazing
The reason, it is because there is air in the oil caused by the road, then, should be exhaust to make it clean.
Fault problem four: pipeline mechanical vibration
The reason, it may be loose pipe, then it should be fastened.
