How to repair the Hydraulic Press Machine when the pressure is insufficient during use

March 10, 2025

20T Hydraulic Press Machine uses special hydraulic oil as the working medium and hydraulic pump as the power source. The hydraulic oil enters the cylinder/piston through the hydraulic pipeline through the power of the pump, and then there is a certain amount of oil in the cylinder/piston. There is a group of seals that cooperate with each other in the cylinder. The seals in different positions have different functions, but they all play a sealing role.

Let me tell you how to repair the Hydraulic Press Machine when it is under-pressure?

1. Check the pressure of the relief valve of the Hydraulic Press Machine. If the pressure is insufficient, adjust the pressure. If it cannot be adjusted, replace the relief valve. If the relief valve is not effective, consider replacing a plunger pump.

2. If the pressure of the Deep Drawing Hydraulic Press is normal, consider whether the electromagnetic reversing valve and the unloading valve have internal leakage.

3. Whether the charging valve of the Hydraulic Hot Pressing Press has internal leakage.

4. Whether the main cylinder of the 20T Hydraulic Hot Pressing Press has internal leakage.
