The oil pressure is not smooth, resulting in abnormal shear PART 2
2025-04-17
Hydraulic cylinder and seal inspection:
Hydraulic cylinder action: Observe whether the shear hydraulic cylinder expansion is smooth, no crawling, abnormal sound and other phenomena. Check that the piston rod is not scratched, bent, and the seal is not aging or damaged.
Replace the seal: If the seal is found to be seriously worn or leaking, replace the new seal in time.
Check the control system:
Electrical wiring: Ensure that the electrical wiring of the control hydraulic system is not loose, damaged, and in good contact.
Electronic control unit: Check whether the electronic control unit (such as PLC, relay, solenoid valve, etc.) works normally, no fault alarm. Make necessary parameter Settings or program adjustments according to the equipment manual.
Machine debugging:
No-load test run: After eliminating the above faults, carry out no-load test run to observe whether the hydraulic system pressure, flow and other parameters are normal, and whether the shear action is smooth.
On-load test: After the no-load test runs normally, the on-load test is carried out to verify the working performance of the shear function under actual conditions.
