What Are The Causes Of Oil Leakage At The Shaft End Of Hydraulic Couplings?

Most of the shaft end of the hydraulic coupling is sealed with an oil seal. The condition for oil seal sealing is to ensure that the shaft and the oil seal lip can form a qualified oil film, and the surface tension generated by the oil film plays a sealing role.

If the machines are not concentric, the fluid coupling shaft will be affected by the radial force caused by the non-concentric installation, and then rotate or beat, which will naturally destroy the oil film formation, so oil leakage may occur. The correct installation of the hydraulic coupling is very important. If the operation is not standardized, many problems will occur.

There are also premature bearing damage and damage to the elastic parts, which will affect the coaxiality. Therefore, I hope that when using a hydraulic coupling, please first read the instruction manual carefully, conduct regular maintenance, and replace worn parts in time.
