Technical field
The utility model relates to a kind of mechanical seal device that is applicable to fields such as oil, chemical industry, papermaking, sewage treatment, specifically is a kind of mechanical seal device that prevents that working fluid from leaking along running shaft.
Background technique
The mechanical seal device of prior art comprises by rotating ring, rubber corrugated pipe, rotating seat, moving ring assembly that spring seat and spring are formed and the static components of forming by stationary ring and stationary ring cover, static components and pump housing drive fit, rotating ring outer wall and rubber corrugated pipe are by the inwall drive fit of stationary ring one end, the longitudinal section of described rotating seat is the step surface of band perpendicular to the end face of axle, the inwall of rotating seat and rubber corrugated pipe are by the outer wall drive fit of stationary ring one end, rubber corrugated pipe is a tight fit on the axle away from the inwall of stationary ring one end, the longitudinal section of described spring seat is the step surface of band perpendicular to the end face of axle, spring seat inwall and rubber corrugated pipe are away from the outer wall drive fit of stationary ring one end, in the middle of the described rubber corrugated pipe two perpendicular to the end face of axle respectively with rotating seat and spring seat perpendicular to two end faces of axle near, spring is against respectively on rotating seat and two end faces of spring seat perpendicular to axle, rotating ring one end face the effect of spring and stationary ring away from the end face of stationary ring cover near.
There is following defective in the seal arrangement of above structure: because described rotating seat and spring seat are separated by far away, during work, rubber corrugated pipe rotates with axle, and drive rotating ring, rotating seat, spring seat and rotate, so rubber corrugated pipe has been born most moment of torsion, the radial vibration of axle or axial float etc. produce the high pulling torque of moment, cause rubber corrugated pipe to tear easily, cause seal failure.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of and can effectively prevent the mechanical seal device that rubber corrugated pipe is torn and then guaranteed to seal.
Technical solution of the present utility model is, a kind of mechanical seal device is provided, comprise by rotating ring, rubber corrugated pipe, rotating seat, moving ring assembly that spring seat and spring are formed and the static components of forming by stationary ring and stationary ring cover, static components and pump housing drive fit, rotating ring outer wall and rubber corrugated pipe are by the inwall drive fit of stationary ring one end, the longitudinal section of described rotating seat is the step surface of band perpendicular to the end face of axle, the inwall of rotating seat and rubber corrugated pipe are by the outer wall drive fit of stationary ring one end, rubber corrugated pipe is a tight fit on the axle away from the inwall of stationary ring one end, the longitudinal section of described spring seat is the step surface of band perpendicular to the end face of axle, spring seat inwall and rubber corrugated pipe are away from the outer wall drive fit of stationary ring one end, in the middle of the described rubber corrugated pipe two perpendicular to the end face of axle respectively with rotating seat and spring seat perpendicular to two end faces of axle near, spring is against respectively on rotating seat and two end faces of spring seat perpendicular to axle, rotating ring one end face the effect of spring and stationary ring away from the end face of stationary ring cover near; The axial projections and the axial recess that cooperatively interact are arranged on the circumferential surface of described rotating seat and spring seat.
After adopting above structure, the utility model mechanical seal device compared with prior art has the following advantages:
Owing on the circumferential surface of described rotating seat and spring seat axial projections and the axial recess that cooperatively interacts arranged, so during work, spring seat drives rotating seat and rotates, so spring seat and rotating seat have been born main moment of torsion, and rubber corrugated pipe is born moment of torsion hardly, so effectively avoided rubber corrugated pipe to tear, thereby guaranteed sealing.
