What is the cause of component wear in a four column hydraulic press

Most people think that it is very normal for mechanical components to wear out after prolonged use. If it is due to wear and tear over time, it is normal because it is inevitable. But sometimes we find that the wear and tear between components is very fast. At this time, we should consider it as a problem of malfunction. Today, let's learn about the reasons for component wear in a four column Hydraulic Press?

1. Wear or deformation of the solenoid directional valve core may affect valve leakage, thereby reducing its working efficiency. Dirt is more likely to enter the gap or deform, leading to mechanical blockage of the valve core. If the gap between the valve core and the valve hole is relatively large, pressure shock may occur.

2. The wear of the pressure reducing valve pilot valve can make the valve unstable or even unable to regulate pressure. The overflow valve pilot cone valve or pilot ball valve is not tightly sealed due to wear and cannot be adjusted correctly.

3. The one-way valve part of the one-way throttle valve (one-way throttle valve) is worn and the seal is not tight, and some oil flow will flow out through the one-way valve, affecting the sensitivity of speed regulation.
