The maximum difference of the lubricated oil-free air compressor of single screw stem water and fuel-injection air compressor is the sealing of lubricated water, do not allow to flow into bearing, the mechanical seal device that must select reliable design, mechanical seal device dynamic and static ring must keep suitable pressure and certain wear resistance each other.Therefore mechanical seal device is a critical component of single screw rod oil-free air compressor.
Existing mechanical seal device, as Fig. 4, the pressure between its rotating ring 1 and stationary ring 2 is constant, and the frictional force of pressure and wear resistance and consumption and sealing effect thereof are all interactive, therefore constant pressure has restricted and has selected a rational Operational Limits.After rotating ring 1 and stationary ring 2 contact surface abrasion, affect contact in addition, need the new mechanical seal device of transposing.
Model utility content
For solving the problems of the technologies described above, we have proposed the adjustable mechanical seal device of pressure between a kind of rotating ring and stationary ring, make it to have rational wear resistance and sealing effect thereof.
For achieving the above object, the technical solution of the utility model is as follows:
For a mechanical seal device for water lubrication list screw rod oil-free air compressor, comprise rotating ring, stationary ring, stationary seat, stationary ring body and a plurality of spring; On described stationary ring body, have a plurality of grooves perpendicular to described stationary ring body anchor ring, described spring is assigned in described groove, and spring one termination is exposed; Described rotating ring one anchor ring contacts with described stationary ring one anchor ring, and another anchor ring of described stationary ring is embedded at described stationary seat one side, and described stationary seat opposite side is embedded in described stationary ring body, and described stationary seat opposite side anchor ring is contacted with described spring end.
Preferably, described stationary seat and described stationary ring body joint are provided with O RunddichtringO.
Preferably, in described groove, be provided with compression spring, described compression spring contacts with another termination of described spring.
Preferably, described bottom portion of groove has screw, in described screw, has assigned adjusting screw, and described adjusting screw end contacts with described compression spring.
Preferably, described groove, spring, compression spring and adjusting screw are ten.
By technique scheme, compared with prior art, its beneficial effect is the utility model: (1), in certain adjusting pressure range, can regulate the pressure between rotating ring and stationary ring, to select rational Operational Limits.(2) after rotating ring and stationary ring contact surface abrasion, pressure can be readjusted, and has extended the working life of mechanical seal device.
