Common welding methods of bag dust collector

　　There are two welding methods commonly used in bag filter, one is spot welding, the other is oxygen acetylene welding.

　　The former method has the advantages of high production efficiency, smooth surface, less burr and small deformation. With the latter method, the production efficiency is low, the surface is rough and easy to deform.

　　In addition, there are also plastic frames, but this kind of frame is not suitable for high temperature use.

　　In the process of blowing, the filter bag will be rubbed with the outer surface of the dedusting frame every time it is cleaned, so the inner surface of the dedusting filter bag has been worn after it has been used for a certain period of time, although it is not damaged, and the contact part of the dedusting frame has been worn. When it is loaded again, the original part can be dislocated according to the wear trace, so as to avoid further wear in the original place, so as to extend the service life of the dedusting filter bag. Dust leakage caused by loose connection.
