What is the cause of oil leakage in high pressure motor bearings (plain bearings)?
The inlet pipe and the oil return pipe joint, oil cup, thermometer socket and valve sealed badThe ventilation system to form a vacuum in the bearing end, lubricating oil from the bearing inside out
2, operation and maintenance reasonsExcessive filling of lubricating oil, exceeding permissible horizontal surfaceNo. of lubricating oil gradesThe bearing seat and the occlusal surface at the old tile indirect sealing paint is not clean cleanNew sealing coating uneven filling, and even forget to fill the paintThe gasket is not properly installed
The reasons for the oil leak in the bearing of the high voltage motor (sliding bearing) are as follows:1, structural and processing reasonsThe structure of shaft seal is not perfectThe bearing seat and tile joint surface deformationPoor seal designTile in the tile seat at the end of the gap between the size of the gap, there is no oil tank, oil seal two, the joint surface gap, tile at both ends without oil blockOil ring processing quality is not enough, the oil ring is uneven: size does not match
