Background technique
Mechanical seal is that a kind of gland seal device of rotating machinery, such as motor, centrifuge, reaction kettle and compressor etc. are electromechanical
Equipment, since transmission shaft is applied in inside and outside equipment, there are a circumferential clearance between axis and equipment, medium in equipment was by should
Gap leaks out, if pressure is subatmospheric in equipment, air is to equipment internal leakage, it is therefore necessary to have a prevention to let out
The gland seal device of leakage.Traditional gland seal device is single-spring mechanical seal structure, only one spring in compensation mechanism, spring
It is sheathed on transmission shaft, it is uneven to act on the pressure on sealing surface for spring in such structure, when the transmission shaft diameter of axle is big
It is more prominent, while when transmission shaft high speed rotation, spring is rotated with transmission shaft, will be occurred because of biggish centrifugal force
The phenomenon that camber of spring, therefore traditional single-spring mechanical seal structure is in the larger limitation of occasion to run at high speed.Multiple springs formula
Mechanical seal is in compensation mechanism containing multiple springs, and feature is to be distributed relatively uniformly, current spring base and throw-out collar it
Between mostly use spring to be directly connected to, in shaft high-speed rotation, there is small distortion in spring, between being between throw-out collar and shaft
Gap cooperation, so small deflection can occur for throw-out collar, causes seal ring of moving ring discontinuity, causes sealing effect bad, and
And seal ring of moving ring is easy Fast Wearing due to discontinuity.
