Double mechanical sealing assembly of waveform spring and preparation technology thereof

Abstract

The invention discloses a double mechanical sealing assembly of a waveform spring. The assembly comprises a stationary ring cover, a rotating ring comprises a first rotating ring sleeve and a second rotating ring sleeve which are formed integrally, and the right end of the stationary ring is in flat fit with the left end of the first rotating ring sleeve; the right side of a rotary shaft is further sleeved with a pushing sleeve and a disc base, the pushing sleeve is located between the rotating ring and the disc base, and the pushing sleeve comprises a pushing disc and a sleeve which are integrally formed; a waveform spring sleeves the sleeve, fixing pins are in screw joint with the edge of the disc base, the tail ends of the fixing pins successively penetrate through the pushing disc, a first through hole and a second through hole, and the first through hole and the second through hole are formed in the surface of the second rotating ring sleeve; a locating pin is arranged at the leftend of the pushing disc and inserted in a locating hole formed in the surface of the second rotating ring sleeve. The waveform spring is clamped between the disc base and the pushing disc and pushesthe pushing disc, the rotating ring is subjected to pressure, and therefore the rotating ring makes contact with the stationary ring for sealing.

Description

technical field [0001] The invention belongs to the technical field of a wave spring double-end mechanical seal assembly, and in particular relates to a wave spring double-end mechanical seal assembly and a preparation process thereof. Background technique [0002] A mechanical seal refers to a device that prevents fluid leakage by at least one pair of end faces perpendicular to the axis of rotation under the action of fluid pressure and the elastic force of the compensation mechanism and the cooperation of auxiliary seals to keep fit and slide relative to each other. [0003] In the double-ended cartridge mechanical seal, there is a phenomenon of poor contact between the moving ring and the static ring, which leads to poor sealing performance during use and affects the safety of the mechanical seal. The structure of the mechanical seal device is complicated, which is not conducive to The installation of the sealing device, and the complex structure will lead to a higher pro...
