【Summary Description】 How to deal with equipment oil leakage in friction welding drill pipe?

First of all,Friction welding drill pipeIn the equipment assembly problem:

1.Deformation of oil seal after press-fitting due to press-fitting tooling;

2.During the assembly process, the oil seal passes through the thread or spline, causing scratches at the lip;

3.Due to the low roughness of the oil seal position, the pressing force is too large, resulting in spring failure or lip turnover.

It's also possible thatDue to the oil seal spring material and manufacturing problems, resulting in its performance failure. The failure mode of the spring is: the spring is too tight or too loose. When the spring is too loose, the spring compression force is small, and the sealing effect cannot be achieved. When the spring is too tight, the spring compression force is large, and the oil seal and the rotating shaft are not properly matched, resulting in abnormal wear of the oil seal. Oil leakage.

It's also possible that one reason is,Friction welding drill pipeThe problem of the shaft The surface of the rotating shaft is defective and the hardness is not suitable, which will also cause oil leakage. And the medium between the two is oil, the choice of oil material also needs to be careful, the two do not fuse will produce lip damage, but also lead to oil leakage.

Friction welding drill pipeThe oil leakage of the equipment needs to be carefully analyzed for the above reasons in order to accurately find the cause of the oil leakage, so as to achieve high efficiency.
