Matters needing attention during maintenance of four-column hydraulic press

After the four-column hydraulic press system is used for a certain period of time, abnormal phenomena or failures occur due to various reasons. At this time, if the method of applying adjustment cannot be ruled out, it can be disassembled for repair or the original part can be replaced. What matters should be paid attention to in the maintenance process of the four-column hydraulic press system? The following is the Shanghai WORLD Press Machine of WORLD Press Machine Machinery to answer your questions:

1. The workplace for disassembly and maintenance must be kept clean, preferably in the purification workshop.

2. During maintenance, the pressure in the four-column hydraulic press system should be completely removed, and at the same time, how to deal with the oil problem of the hydraulic press system should be considered. In special cases, the oil in the hydraulic press system can be removed.

3. When disassembling the oil pipe, clean the surrounding parts of the oil pipe in advance. After disassembling, wrap the oil pipe with clean plastic products or paraffin paper at the opening of the oil pipe. Do not block the oil pipe with cotton yarn or rags, and pay attention to the mixing of impurities.

4. When disassembling complicated pipelines, a numbered white iron sheet or plastic sheet should be tied at the connection of each oil pipe to facilitate assembly, so as not to install the oil pipe by mistake.

5. During installation or maintenance, the sharp corners of the parts in contact with the O-ring or other seals should be blunted to prevent the seal from being stabbed by sharp corners or burrs.

6. When replacing rubber seals, do not use sharp tools, and be careful not to bruise the working surface.

7. When disassembling, the components and parts of each four-column hydraulic press should be properly preserved and placed, and should not be lost.

8. There are many high-precision machined surfaces in the components of the four-column hydraulic press. When disassembling and assembling, do not bruise the machined surface by tools or other things. Special attention should be paid to the layout and preparation of the work environment.

9. It is best to use appropriate tools when disassembling, so as to avoid damage such as hexagon sockets and sharp corners or screw off screws.

10. When disassembling and reassembling, all parts must be cleaned.

11. Before assembly, the O-ring or other seals should be immersed in oil for use. During assembly or after assembly, the seal should not be twisted, and it should be ensured that the Lubrication properties.

12. Do not use excessive tightening force when installing four-column hydraulic press components or pipe joints. In particular, it is necessary to prevent the deformation of the hydraulic component housing, and the spool of the spool valve cannot slide to prevent oil leakage at the joint.

13. If the movable parts of the four-column hydraulic press may drop under the action of gravity, the movable parts should be firmly supported by the support frame.
