Damping type corrugated pipe compensation moving ring component of mechanical sealing device and application

Abstract

The invention discloses a damping type corrugated pipe compensation moving ring component of a mechanical sealing device. The damping type corrugated pipe compensation moving ring component comprises a moving friction ring (1), a moving friction ring base (2), a welded metal corrugated pipe (3), a tailstock (4), a transmission seat (5) and a seal ring (6), and is characterized in that a ring housing (8) is fixedly connected to the tailstock (4); and a damper (9) is fixedly connected to an inner ring surface (82) at the front end (81) of the ring housing (8) and is in contact matching with an outer ring surface of the welded metal corrugated pipe (3) to achieve a damping effect on the welded metal corrugated pipe (3), thereby avoiding and lightening the problem that the welded metal corrugated pipe is fractured due to vibration, and prolonging the service life of mechanical sealing.

Description

technical field [0001] The invention relates to a mechanical seal device, in particular to a bellows compensating moving ring assembly of the mechanical seal device. [0002] technical background [0003] The mechanical seal device is composed of a pair of friction pairs perpendicular to the axial direction, an elastic compensation mechanism for closing the friction pairs, a transmission torque mechanism, and an auxiliary sealing ring, that is, a moving ring assembly and a static ring assembly. [0004] The compensation mechanism is set on the moving ring assembly and rotates with the shaft. It is a moving ring compensation type mechanical seal device, which is mostly used in occasions where the requirements for working conditions are not too high. [0005] The elastic compensation mechanism of the dynamic ring of the dynamic ring compensation type mechanical seal device is divided into a spring type compensation mechanism and a welded metal bellows compensation mechanism. ...

AI Technical Summary

Problems solved by technology

[0007] The obvious use defect of the welded metal bellows is that it will break, and part of the reason for the fracture of the welded metal bellows is that the welded metal bellows vibrates during work. When the vibration frequency is close to the natural vibration of the welded metal bellows When the frequency is high, resonance will occur, which will increase the fatigue fracture of the welded metal bellows and reduce the service life
