Precautions for seal hydraulic press

by:WORLD     2022-09-27
I believe everyone knows that the hydraulic press does not exist alone, it also has many components. So in terms of the use of the seal hydraulic press, what aspects should we pay attention to? I also hope that this introduction can give our users some suggestions and help.

The seal is used to prevent the leakage of high-pressure liquid, and it is a wearing part. If the quality is not good, it will seriously affect the normal operation of the hydraulic press. Therefore, the basic requirements for seals are: good sealing performance, can improve its sealing performance with the increase of liquid pressure, low friction resistance, small wear, long life, simple maintenance, easy replacement, low cost, and easy to use. manufacture.

The seal between the cylinder and the piston or plunger, valve, hydraulic pump plunger, etc. in the hydraulic press becomes the dynamic seal between the surfaces of the relatively moving parts; the joints between the pipe joint, the valve seat and the valve sleeve, and the combined cylinder become the dynamic seal. Static seal between fixture surfaces.

The service life of seals often varies greatly, some can be used for more than a year or two, and some even need to be replaced in a few days. The reason is mainly caused by the following factors: the material, shape, dimensional accuracy and manufacturing quality of the sealing ring; the surface condition of the sealed part; the nature, temperature and cleanliness of the working liquid; Fit and work installation is correct, etc. Therefore, pay attention to the above factors in use, and use them reasonably to effectively extend the service life of the hydraulic press.
