After the mechanical equipment has been used for a period of time, there will be some failures in various parts. We have to disassemble and repair the failure of scrap machines, and there are many precautions in the disassembly of some parts. The following are the precautions when disassembling the oil pipe of the hydraulic guillotine shearing machine provided by MYT(Shanghai) Machinery Equipment Co., Ltd.
1. Clean the surrounding parts of the oil pipes of the hydraulic guillotine shearing machine beforehand.
After disassembly, wrap the tubing with clean plastic or paraffin paper at the opening of the tubing and take care to avoid mixing of impurities.
2. When installing or overhauling the hydraulic guillotine shearing machine, the sharp corners of the parts in contact with the seal should be repaired to a relatively obtuse angle to prevent the seal ring from being scratched by the sharp corners or burrs.
When replacing rubber seals, do not use sharp tools or scratch the surface.
3. When disassembling and then assembling the hydraulic guillotine shearing machine, its parts must be cleaned.
4. Before assembling the hydraulic guillotine shearing machine, the seals should be immersed in oil for use.
When assembling or after assembling the hydraulic guillotine shearing machine, the sealing ring should not be twisted, and the lubrication performance during the sliding process should be ensured.
5. It is necessary to prevent the deformation of the hydraulic component shell of the hydraulic guillotine shearing machine, the jam of the spool valve core, and the oil leakage of the joint parts.
When installing hydraulic components or pipe joints, the tightening force should be appropriate.
