China Hydraulic punch press

There may be various reasons why China Hydraulic punch press do not return, and the following are some common reasons and solutions:

1. Insufficient system pressure: First, check whether the system pressure of the hydraulic punch meets the requirements. If the system pressure is insufficient, it may cause the hydraulic cylinder to be unable to generate sufficient thrust to return the punch. At this point, it is necessary to check whether the oil pump is damaged, whether the pump body is overheated, and replace and maintain it in a timely manner. At the same time, check whether the hydraulic cylinder and valves are normal and ensure that they are in normal condition.

2. Hydraulic cylinder blockage: The hydraulic cylinder is an important component of the punch press device. If the hydraulic cylinder is blocked, it will cause the hydraulic punch press to not return. Possible reasons include loose seals, oil leakage, and waste stuck inside. The solution is to check and replace the seals, clean the hydraulic cylinder, and reinstall the seals.
3. Oil contamination: Oil contamination can cause hydraulic components in the system to fail or become blocked, resulting in non return faults. Therefore, it is necessary to regularly clean and replace the oil, while maintaining the stability of the hydraulic components through oil system maintenance.
4. Hydraulic valve failure: Hydraulic valve failure is also one of the reasons for the non return condition of hydraulic punch press. If the valve malfunctions, it needs to be shut down for maintenance and replacement of faulty parts to ensure the normal operation of the hydraulic press.
5. Circuit issues: In some cases, circuit issues may also cause hydraulic presses to not return. For example, the coil of the solenoid valve may get stuck, and the pressure of the pilot high-pressure safety valve may be too low. At this point, it is necessary to check whether the circuit is moving, whether the solenoid valve is stuck, and whether the pressure of the pilot valve is normal.
In summary, the reasons for the non return of hydraulic punch press may involve multiple aspects such as system pressure, hydraulic cylinders, oil contamination, hydraulic valves, and circuits. When encountering such problems, they should be investigated one by one and corresponding solutions should be taken. At the same time, daily maintenance is also very important, which can increase the service life of equipment and improve work efficiency.
