Manufacturing method of small-spring double-end-face mechanical seal device

Abstract

The invention discloses a manufacturing method of a small-spring double-end-face mechanical seal device. The small-spring double-end-face mechanical seal device comprises a gland, a first housing, a second housing, a first movable ring, a first stationary ring, a second stationary ring, a second movable ring, a first spring, a first fixing base, a second fixing base, a washer, a first push ring and a second push ring, a first fixed ring, a second fixed ring, a first stationary ring seal ring, a second stationary ring seal ring, a first movable stationary ring seal ring, a second stationary ring seal ring, a waterproof ring, a rotary shaft and a second spring. Compared with the prior art, the manufacturing method of a small-spring double-end-face mechanical seal device adopts the design ofprotruding portions of the bottom sides of the first stationary ring, the second stationary ring, the first fixed ring and the second fixed ring on two sides, so that the first stationary ring seal ring, the first movable ring, the second stationary ring seal ring, the second ring, the first movable ring seal ring and the second movable ring seal ring 7 are better corresponding clamped and fixed,corresponding structures are better stabilized, and the corresponding sealing performance is better.

Description

Technical field [0001] The invention relates to the technical field of mechanical seals, in particular to a method for manufacturing a small spring double-end mechanical seal device. Background technique [0002] A mechanical seal refers to a device that prevents fluid leakage by keeping at least a pair of end faces perpendicular to the axis of rotation under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal to prevent fluid leakage; It is a shaft sealing device for rotating machinery, such as centrifugal pumps, centrifuges, reactors, compressors and other equipment. Since the transmission shaft runs through the inside and outside of the equipment, there is a circumferential gap between the shaft and the equipment, and the medium in the equipment passes The gap leaks to the outside. If the pressure in the equipment is lower than the atmospheric pressure, the air leaks into the equipment, ...

AI Technical Summary

Problems solved by technology

There are many types of shaft seals. Because mechanical seals have the advantages of less leakage and long life, mechanical seals are the most important shaft sealing methods for these equipment in the world; mechanical seals are also called end face seals, but traditional mechanical seals are mostly through The fricti
