Ground improves leakproofness.But the inevitably vibration problem in the operational process of water pump, in addition the medium of conveying is more
For solidliquid mixture, the reduction of contact surface sealing performance frequently can lead to, so as to cause leakage accident, reduce the efficiency of pump, influence
Its normal use.
Summary of the invention
To solve the above problems, being set in sealing structure cavity the present invention relates to a kind of sealing structure of automatic coupling device
The air bag set is squeezed the radial force that sealing device shell generates by pumped (conveying) medium and compressed, and is deformed, is connect to generate to sealing
The pressing force of contacting surface, with the uniform wear of seal face, the elastic energy of sealing block storage gradually discharges, to play axial direction
Compensating action can greatly improve the leakproofness of contact surface.
The purpose of the present invention is achieved through the following technical solutions:
