Integral packaging type mechanical seal device

Abstract

The invention discloses an integral packaging type mechanical seal device. The integral packaging type mechanical seal device comprises a mechanical shaft, movable rings and fixed rings; the movable rings comprise the first movable ring and the second movable ring, the fixed rings comprise the first fixed ring and the second fixed ring, the device further comprises movable ring shaft casing pipes,a gland and a mechanical seal fixing flange, the movable ring shaft casing pipes comprise the first movable ring shaft casing pipe and the second movable ring shaft casing pipe, the first movable ring shaft casing pipe is arranged on the mechanical shaft and between the movable rings and the fixed rings, the two movable rings are arranged at the two ends, the fixed rings are arranged between thetwo movable rings, the second movable ring shaft casing pipe is adjacent to the second movable ring, and the second movable ring shaft casing pipe is arranged outside the first movable ring shaft casing pipe; the first fixed ring and the second fixed ring are sleeved with the gland with a water inlet and a water outlet, and the gland is connected with the mechanical seal fixing flange; and a sealcavity is formed among the gland, the movable rings, the fixed rings and the movable ring shaft casing pipes. The integral packaging type mechanical seal device is compact in structure, easy to mount,convenient to use, good in dynamic balance, durable, capable of being used for sealing of the solid and liquid particle mixture working condition and high in belt pressing seal durability.

Description

technical field [0001] The invention relates to the technical field of mechanical seals, in particular to a cartridge-type mechanical seal device applicable to the working condition of solid-liquid-powder particle mixture, convenient for installation and replacement, and good in pressurized seal durability. Background technique [0002] Mechanical seal (mechanical seal) refers to at least one 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 keep fit and slide relative to prevent fluid leakage. device. [0003] A mechanical seal is a shaft seal device for a rotating machine. Such as centrifugal pumps, centrifuges, reactors and 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 ...

AI Technical Summary

Problems solved by technology

The end face is stuck due to particles, and the elastic volume cannot be compensated, resulting in the inability to effectively fit the dynamic and static ends and cause leakage, so it is not suitable for the use of solid-liquid-powder particle mixtures

[0006] 2. The existing structure is bulk type, because the mechanical dynamic seal needs high-precision coordination, and the spring compensation must be adjusted, so it needs professional installation, which is labor-intensive and time-consuming

[0007] 3. The durability of the pressure seal is poor
