Description
Technical field
This utility model relates to technical field of mechanical, particularly relates to one and is applicable to solid-liquid powder granule mixture
The integrated mechanical sealing device convenient, on-line pressure sealant ruggedness is good is changed in operating mode, installation.
Background technology
Mechanical seal (mechanical seal) refers to be perpendicular to the end face of rotation axis at fluid pressure by least one pair of
Effect with compensation mechanism elastic force (or magnetic force) lower and auxiliary seal coordinate lower holding laminating relative slip are constituted
Prevent the device that fluid leaks.
Mechanical seal is the gland seal device of a kind of rotating machinery.Such as centrifugal pump, centrifuge, reactor and compressor etc. set
Standby.Owing to power transmission shaft is applied in inside and outside equipment, so, there is a circumferential clearance between axle and equipment, the medium in equipment leads to
Crossing this gap to leak out, if pressure subatmospheric in equipment, then air is to equipment internal leakage, it is therefore necessary to have a resistance
The gland seal device of stopping leak leakage.The kind of axle envelope is a lot, owing to mechanical seal has that leakage rate is few and the advantage such as life-span length, so generation
In boundary, mechanical seal is in these equipment topmost sealing mode.End face seal is named again in mechanical seal, at the relevant mark of country
Standard is defined such that and " is perpendicular to the end face of rotation axis at fluid pressure and compensation mechanism elastic force (or magnetic by least one pair of
Power) effect and coordinating of auxiliary seal lower keep laminating and relatively slide and the device preventing fluid from leaking that constitutes.”
The critical piece of mechanical seal has rotating ring and stationary ring, also auxiliary sealing member and stretch compensation mechanism, existing machine
Tool seals and has the disadvantage in that
1, existing mechanical seal structure is at random, and stationary ring is distributed in both sides, is not suitable for solid-liquid powder granule mixture
The use of operating mode.End face blocks because of particulate matter, and cannot be carried out bullet amount back-off, causes sound both ends of the surface can not effectively fit generation
Leakage, thus it is not suitable for the use of solid-liquid powder granule mixture operating mode.
2, existing structure is bulk type, because mechanical dynamic seal needs high accuracy to coordinate, and spring back-off amount to be regulated,
So needing professional to install, time-consuming.
3, on-line pressure sealant poor durability.When being increased beyond spring force by the pressure in annular seal space body, dynamic and static ring end face
I.e. can not effectively fit.
