The utility model relates to a kind of mechanical seal structure device, particularly a kind of anticlogging mechanical seal structure device of rubber corrugated pipe that is applied to contain impurity and the high medium operating mode of viscosity.
Background technique
Mechanical seal is in the application of fluid machinery; if impurity is more or viscosity is higher in the medium; the mechanical seal meeting is because medium spring blocking or slide member; seal ring can not in time compensate; sealing surface is broken away from; cause mechanical seal to lose efficacy, and then the leakage that causes, shut down to have a strong impact on and produce and environmental protection.
Summary of the invention
At the not good present situation of sealing effect in the fluid machinery, the utility model provides a kind of Anticlogging mechanical sealing device.
To achieve these goals, the measure taked of the utility model is:
A kind of Anticlogging mechanical sealing device, comprise rotary component and static part, rotary component comprises the axle sleeve that is fixed on the running shaft, be provided with axle sleeve O shape circle between axle sleeve and the running shaft, rotating ring is connected an end of axle sleeve by pin, be provided with rotating ring O shape circle between rotating ring and the axle sleeve, be connected with driving ring on the other end of axle sleeve, the static part that is connected with the pump seal end cap comprises the stationary ring and the stationary seat that is connected with the stationary ring interference that links to each other with rotating ring, stationary seat and be connected with and be provided with stationary ring O shape circle between the end cover of end cap pad, the spring seat of spring fixedly is housed on the stationary seat, the back side of stationary seat is connected with rubber corrugated pipe, and stationary seat back breach is connected with throw-out collar;
Described seal ring adopts the balanced mechanical seal constructional device;
Described rubber corrugated pipe is by being connected on the stationary seat with the collar interference;
Described spring seat adopts screw orientation type from inside to outside to be fixed on the end cover by screw;
The rear portion interference of described end cover is connected with outside framework oil seal;
Be connected with limiting stopper by screw on the described driving ring.
The beneficial effects of the utility model: increase rubber corrugated pipe at the stationary seat back side, impurity can not be contacted with quiet O shape circle, prevent that impurity from stopping up the seal failure that quiet O shape circle causes; Be fixed on the rubber corrugated pipe on stationary seat and the end cover, be close to circle and clamp with the rubber corrugated pipe interference, safe and reliable; Adopt the balanced mechanical seal constructional device, can reduce pressure medium effectively and act on the active force that seals on the anchor ring; Use external cleaning cooling water, can in time take away the heat of rotating ring and stationary ring product; Use outside framework oil seal, stifled disconnected external cleaning cooling water leaks to atmosphere.
