Technical field
The present invention relates to technical field of mechanical, more particularly to it is a kind of be applicable to solid-liquid powder granule mixture operating mode, installation is changed integrated mechanical sealing device convenient, that on-line pressure sealant durability is good.
Background technology
Mechanical seal (mechanical seal) refers to by least one pair of perpendicular to the end face of rotation axis in Fluid pressure and compensation mechanism elastic force（Or magnetic force）In the presence of and the cooperation of auxiliary seal under keep be bonded and formed with respect to slip prevent fluid leak device.
Mechanical seal is a kind of gland seal device of rotating machinery.Such as the equipment such as centrifugal pump, centrifuge, reactor and compressor.Because power transmission shaft is applied in inside and outside equipment, so, a circumferential clearance between axle and equipment be present, medium in equipment is leaked out by the gap, if pressure subatmospheric in equipment, air is to equipment internal leakage, it is therefore necessary to has a gland seal device for preventing leakage.The species of axle envelope is a lot, because mechanical seal has the advantages that leakage rate is few and long lifespan, so mechanical seal is in the most important sealing mode of these equipment in the world.Mechanical seal is called end face seal, is defined as in relative national standards：" by least one pair of perpendicular to the end face of rotation axis in Fluid pressure and compensation mechanism elastic force（Or magnetic force）Effect and auxiliary seal cooperation under keep be bonded and formed with respect to slip prevent fluid leak device.”
The critical piece of mechanical seal has rotating ring and stationary ring, also auxiliary sealing member and stretch compensation mechanism, and existing mechanical seal has the following disadvantages：
1st, existing mechanical seal structure is at random, and stationary ring is distributed in both sides, is not suitable for the use of solid-liquid powder granule mixture operating mode.End face can not carry out bullet amount back-off because particulate matter blocks, and cause sound both ends of the surface to be effectively bonded generation leakage, thus not be suitable for the use of solid-liquid powder granule mixture operating mode.
2nd, existing structure is bulk type, because mechanical dynamic seal needs high accuracy to coordinate, and to regulate spring back-off amount, so need professional to install, it is time-consuming.
3rd, on-line pressure sealant poor durability.When pressure in by seal cavity is increased beyond spring force, dynamic and static ring end face can not be effectively bonded.
