Problems solved by technology

[0002] During the long-term high-frequency use of rotating shafts, the original hardness layer on the surface of the journal will be destroyed after long-term high-speed continuous wear between the shaft and the seal, and the pressurized medium will travel along the wear groove between the seal and the shaft. Leakage from the gap between them will cause waste of pressurized medium and pollute the working environment
The traditional maintenance method is to replace the shaft and sealing ring as a whole, so as to solve the leakage problem of the pressurized medium of the rotating shaft. This maintenance method has a high maintenance cost and is easy to cause repair waste.

Abstract

The invention relates to a rotating shaft seal repairing method. The method comprises the steps of repairing material selection, pre-machining before repairing, a repairing implementation procedure and repairing post-treatment. The repairing method is simple and easy to master, a shaft neck is not prone to being damaged, and if abrasion is serious and frequent, a bearing inner ring can be replaced many times for repeated use; and the working efficiency of maintenance can be effectively improved, the maintenance time is shortened, and the maintenance cost is saved.

Description

technical field [0001] The invention relates to the field of repairing the rotating shaft seal, in particular to a repairing method for the rotating shaft seal. Background technique [0002] During the long-term high-frequency use of rotating shafts, the original hardness layer on the surface of the journal will be destroyed after long-term high-speed continuous wear between the shaft and the seal, and the pressurized medium will travel along the wear groove between the seal and the shaft. The gap between them leaks out, causing waste of pressurized medium and polluting the working environment. The traditional maintenance method is to replace the shaft and sealing ring as a whole, so as to solve the leakage problem of the pressurized medium of the rotating shaft. This maintenance method has high maintenance costs and is likely to cause repair waste. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for re...
