How to troubleshoot hydraulic shears
- Oct 16, 2018 -

1. Check the circuit of the hydraulic shearing machine and tighten it. The valve of the reversing valve is stuck.

2. The slider can only be repaired or replaced by tightening the housing fixing screw.

3. Look at the actual situation of the hydraulic system of the shearing machine and observe whether there are problems with the system pressure, speed, oil, leakage, vibration, etc.

4. Listen to the sound of the shearing machine hydraulic system, such as: impact sound; pump noise and abnormal sound; determine whether the hydraulic system works normally.

5. The piston cylinder piston seal ring is seriously worn and the seal ring is replaced.

6. Touch the temperature rise, vibration, creep and the tightness of the joint to determine whether the working condition of the moving parts of the hydraulic system of the shearing machine is normal.

7. It may be that the hydraulic shearing machine spring is loose. Tighten the pressure relay handwheel clockwise and the pressure relay is faulty. Press the spring.
