Abstract

The mechanical sealing device for the pump comprises a static ring assembly (1) and a movable ring assembly (2) which are matched with each other, and the movable ring assembly (2) comprises movable ring rubber (5), a movable ring (6) and a spring (8) which are coaxially arranged; the movable ring (6) is tightly attached to the static ring assembly (1) and fixed in one end of the movable ring rubber (5), the movable ring rubber (5) is sleeved with a pair of positioning sleeves (7) which are oppositely arranged and can be matched in a buckled mode, and the spring (8) is arranged between the pair of positioning sleeves (7) in a sleeved mode. All the components are tightly connected, and a good mechanical sealing effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical seals, in particular to a pump mechanical seal device and a use method. Background technique [0002] The mechanical seal structure consists of only two parts: a rotating part and a stationary part. The overall structure of the mechanical seal is a single-end seal, unbalanced, arbitrary rotation, and rubber bellows. The working principle of the mechanical seal is to push the moving ring through the rubber bellows installed in the rotating part on the shaft. The rubber bellows is not only the secondary seal, but also the driving part of the moving ring, so as to fit the stationary ring and prevent the fluid in the pump from moving along the shaft. Face seal against leaks. For example, the Chinese utility model patent with the publication number CN203627292U discloses a mechanical seal structure for pumps, which includes a rubber bellows sleeved on the rotating shaft. A moving ring is embedded...
