The impeller fixing ring is generally a ring-shaped fixing device composed of two or three semicircles assembled together, which can be disassembled directly. The shaft sleeve matched with the impeller fixing ring must be removed after removing the spare parts serially mounted on the drive shaft such as the pump casing and the impeller mechanical seal. Therefore, the mechanical seal positioning shaft sleeve must be modified to make it resemble the impeller positioning ring. The same is changed to two semicircles assembled into a ring sleeve. When performing mechanical seal online maintenance, remove the impeller fixing ring and shaft sleeve separately, the mechanical seal shaft sleeve has a certain amount of space for movement, and the mechanical seal can be moved by sliding the mechanical seal moving ring and mechanical seal sleeve on the shaft. Inspection of the end face of the ring bracket and the end face of the moving ring and the end face of the static ring, and the replacement and cleaning of the O-ring and the compression spring.　　213.html,
