Problems solved by technology
[0003] In the process of converting mechanical energy into liquid energy in a centrifugal pump, the centrifugal pump shaft plays a key role. The sealing effect of the sealing structure often determines the quality of the centrifugal pump, and the disassembly and installation of the sealing structure will also bring great harm to the use of the centrifugal pump. Therefore, we propose a centrifugal pump shaft seal wear-resistant sealing mechanism and its production method to solve the problems mentioned in the above background technology

The invention discloses a centrifugal pump shaft seal wear-resistant sealing mechanism. The centrifugal pump shaft seal wear-resistant sealing mechanism comprising a centrifugal pump body, a sealing cylinder and a centrifugal pump shaft is characterized in that a connecting cylinder is disposed in the middle of the left end of the centrifugal pump body; a limiting convex ring is arranged on the inner cavity wall of the right side of the connecting cylinder; a first bearing is disposed on the inner cavity of the connecting cylinder and located on the left side of the limiting convex ring; the left end of the sealing cylinder is open; a through hole is opened in the middle of the right end of the sealing cylinder; a second bearing and a seal ring are sequentially disposed on the inner portion of the sealing cylinder from left to right; a sealed end cap, the second bearing, the seal ring, the through hole and the first bearing sequentially run through right end of the centrifugal pump shaft and extend into the inner cavity of the centrifugal pump body. The centrifugal pump shaft seal wear-resistant sealing mechanism has the advantage of improving sealing effect on the centrifugal pumpshaft with the seal ring mounted inside the sealing cylinder, a first plug cylinder inserted into the sealing cylinder through the opening at the left end of the sealing cylinder, the right end of the first plug cylinder abutting against the left end surface of the second bearing, a second plug cylinder inserted into the connecting cylinder through the left end of the connecting cylinder, and theright end of the second plug cylinder abutting against the left end surface of the sealing cylinder.
Description
technical field [0001] The invention belongs to the technical field of a shaft seal wear-resistant sealing mechanism of a centrifugal pump, and in particular relates to a shaft seal wear-resistant sealing mechanism of a centrifugal pump and a production method thereof. Background technique [0002] The pump is a general-purpose machine that is widely used. There are many types. It is widely used in various sectors of the national economy. It is the most widely used type of various pumps. , shipbuilding industry, farm irrigation and other fields. [0003] In the process of converting mechanical energy into liquid energy in a centrifugal pump, the centrifugal pump shaft plays a key role. The sealing effect of the sealing structure often determines the quality of the centrifugal pump, and the disassembly and installation of the sealing structure will also bring great harm to the use of the centrifugal pump. Therefore, we propose a centrifugal pump shaft seal wear-resistant sea...
