The oil seal is the hydraulic component used to seal the oil and stop the oil flow in the hydraulic press, the improper installation of the hydraulic oil seal will shorten the service life or lead to oil leakage, which affects the normal use of the hydraulic system, so the installation of the oil seal should be done, then, how is the hydraulic press manufacturer to correctly install the oil seal?
1, the installation of the oil seal should check whether the size of the oil seal matches the shaft and hole.
2, the oil seal should be used without any damage, such as dents, scratches or scratches, etc. If the seal is dirty, clean it carefully.
3, the outer ring of the oil seal with the chamfer of the hole is scratched.
4, the shaft surface should be clean, without any damage, such as damage, scratches, cracks, rust or chamfered burrs and other defects.
5, the oil seal is chamfered or round through the shaft end.
6, before installation, should first apply some lubricating oil or grease seal lip.
Hydraulic machinery manufacturers, oil seals, like other lip seals, use the same principles as the use of sealing rings. Also, according to the rotation axis.
