Constitute with transmitting torque mechanism, auxiliary seal ring, i.e., be made up of moving ring assembly and static components,
Compensation mechanism be arranged on rotate with the axis on moving ring assembly for rotating ring compensation type mechanical seal device, applied in operating mode mostly
The less high occasion of parameter request.
The elastic compensating mechanism of rotating ring its rotating ring of compensation type mechanical seal device is divided into spring compensation mechanism and welding gold
Category bellow-type expansion mechanism.
The excellent performances such as welded metal bellow compensation mechanism sealing, elasticity, torsional rigid, resistance to pressure, heat-resisting quantity.
Welded metal bellow is significantly to produce fracture using defect, and the part of welded metal bellow fracture
Reason, is because that welded metal bellow operationally generates vibration, when the frequency of vibration is close to welded metal bellow
The natural frequency of vibration when, will produce resonance, increase and cause welded metal bellow fatigue fracture, reduce service life.
Content of the invention
It is an object of the invention to provide the damp type corrugated tube of a kind of function admirable, the mechanically-sealing apparatus of working life length
Compensation moving ring assembly and application.
The present invention mitigates mechanically-sealing apparatus in use by increasing damper mechanism to welded metal bellow
The nuisance vibration that welded metal bellow is produced, it is to avoid produce resonance, it is to avoid and mitigation welded metal bellow is produced because vibrating
Breakage problem, so as to extend the service life of welded metal bellow, improve using welded metal bellow compensation rotating ring
The service life of mechanical seal.
The damp type bellow-type expansion moving ring assembly of mechanically-sealing apparatus of the present invention, includes dynamic friction ring 1, dynamic friction ring
Seat 2, welded metal bellow 3, tailstock 4 and retainer 5, sealing ring 6, the front and back end of welded metal bellow 3 is rubbed with dynamic respectively
Wipe ring seat 2 and tailstock 4 to be welded to connect, it is characterized in that being fixedly connected on tailstock 4 and be provided with ring set 8, the rearward end 80 of ring set 8 and tail
Seat 4 is fixedly connected, and the front end 81 of ring set 8 is opening, and the front end 81 of ring set 8 extends the front portion for causing welded metal bellow 3,
It is fixedly connected on the inner ring surface 82 of the front end 81 of ring set 8 and antivibrator 9 is provided with, the medial surface of antivibrator 9 and welded metal bellow 3
Outer ring surface be engaged, damping action is carried out to welded metal bellow 3, antivibrator 9 is have the elastomer of radial elastic, resistance
Buddhist nun's device 9 is circular ring structure, and antivibrator 9 can be that annular component or be uniformly distributed by multiple damping block anchor rings is constituted.
Present invention manufacture is easy, and damper mechanism can effectively mitigate the nuisance vibration of welded metal bellow generation, it is to avoid
Produce resonance, it is to avoid and mitigate the breakage problem that welded metal bellow is produced because of vibration, improve the service life of mechanical seal.
