The design of the original mechanically adjustable seal is relatively perfect, both in terms of structure and material selection are very scientific and advanced, fully suitable for the needs of pumping acid. From the actual site situation of the original mechanical seal, when a large amount of iron oxide accumulates in the acid solution, the main seal dynamic ring and static ring of the mechanical seal will wear quickly, which leads to the failure of the mechanical seal and the cam The root cause of shaft fracture is the wear of the fuel injection pump body. For the fracture of the camshaft, we can use the following methods to solve it. The following are camshaft wholesalers, camshaft manufacturers and camshaft brand companies.
1. Butterfly valve can be used to weld the pump body by electric welding and brazing. The thickness and area of the heap are larger than the amount of wear. After welding, the method of filing and grinding can be used to polish and flatten the welded part to restore its original shape.
2. The method of metal glue filling. To repair the pump body of the fuel injection pump, apply the prepared metal glue on the wear area of the gate valve. The thickness and area of the metal glue coating should be slightly larger than the wear amount. After solidification, polish the area coated with the metal glue, and then install it. Debugging is fine.
