Description
Technical field
The present invention relates to a kind of bottom mechanically-sealing apparatus.
Background technique
Modern times sealing mainly has: traditional packing seal, mechanical seal, pureed sealing, cartridge seal etc., wherein applying
It is most widely mechanical seal, but mechanical seal also exposes many deficiencies in the application, this sealing is mostly rotary
Mechanical seal, spring is in sealing medium side, and performance is unstable and spring is easy failure, although state type mechanical seal spring is not
In sealing medium side, but ring is compensated also not in sealing medium side, under normal circumstances, compensation ring is more steady in sealing medium side
It is fixed reliable.
A kind of mechanical sealing structure for pump comprising the rubber bellows being set on the shaft, the rubber bellows lean on
One end of nearly pump cover is provided with annular groove, and the annular groove is embedded with rotating ring, the position of two close end is leaned on the outside of the rubber bellows
It sets and is also respectively formed with step, spring base and rear spring seat before being respectively arranged on the step, the outer position of the rubber bellows
Position between the preceding spring base and rear spring seat is set with to apply elasticity to the preceding spring base and rear spring seat
The spring of power；It is provided with stationary ring in the pump cover, radial seal, the rotating ring are provided between the stationary ring and the pump cover
Connect including the circular body portion being located in the annular groove and with the main part and the diminishing tapering of size, it is described
Tapering is resisted against on the stationary ring.The problem of above patent document is that shaft fully relies on rubber corrugated in rotation
The torsion that pipe generates drives the rotating ring rotation on preceding spring base and preceding spring base, this causes rubber bellows to be easy to be twisted off in turn
Lead to seal failure, influences sealing performance.
Bottom entering type mechanical seal is directly contacted with material in kettle, and working condition is harsh, complicated, and temperature is higher, pressure is larger,
Some media are inflammable, explosive, containing solid particle and have certain viscosity, certain vibration and pendulum can be generated in equipment running process
It is dynamic, it requires mechanical seal can reach a high temperature, high pressure, No leakage and the requirement for having certain adaptability to the swing of host.
Traditional mechanical seal is since media end seals inborn design structure, when encountering the operating condition that particle is big, viscosity is high
When media end compensation ring and auxiliary seal be easy to fail, cause the leakage of mechanical seal.
Due to the particularity of bottom entering type equipment, mechanical seal after the installation is completed, mechanical seal sleeve can generate certain
Displacement, in addition tradition machinery sealing bearing uses deep hook ball bearing, and deep groove ball bearing bearing can not adjust mechanical seal and set
Out of plumb and the situation of decentraction between standby, to shorten the service life of sealing.Under high pressure operating condition, atmosphere end and medium
The abrasion loss at end is inconsistent, causes the shortening of sealing life.
