Abstract
The utility model discloses a mechanical seal for a novel slurry pump with high damping property. The mechanical seal at least comprises a static ring and a static ring seat; the static ring is arranged on the static ring seat; and a static ring damping O-shaped ring is arranged on the static ring. A convex ring is arranged at the contact end of the static ring and the static ring seat. The static ring damping O-shaped ring is positioned on the convex ring of the static ring. Through the mechanical seal, the static ring has a certain axial compensation function, and the defect that the friction end face is not tightly attached due to vibration of equipment is overcome; and the reliability of the mechanical seal is improved, the service life of the mechanical seal is prolonged, and the maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of seal arrangement technical field, is specifically related to a kind of high damping new-type mortar mechanical seal for pump.
Background technique
In oil gas drilling process, contain a large amount of mud and a small amount of sand grains in the pipeline, owing to be located in field condition washing solution can't be provided, the mechanical seal Environmental Conditions of material-handling pump is quite abominable.In order to solve particle, mud medium difficulty of transportation in pump; Cause seal leakage, problems such as inefficacy, existing technology have adopted following mode to solve: 1, increase auxiliary system; Adopt measures such as filtration, flushing, insulation; Improve the medium situation, but expense is high, takes up room, the installation and maintenance workload is big; 2, select rubber bellows mechanical seal for use, because there is following shortcoming in existing rubber bellows mechanical seal: can not guarantee that stationary ring and stationary seat abrasive end face remain under the big situation of vibration equipment fits tightly, and causes face leakage.
In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of new solution.
The model utility content
The utility model technical problem to be solved is: to the deficiency of existing technology; A kind of high damping new-type mortar mechanical seal for pump is provided; This high damping new-type mortar mechanical seal for pump makes stationary ring and stationary seat flexibility contact; Stationary ring has certain nose balance function, has overcome the not tight influence of abrasive end face applying that vibration equipment brings; Improve the reliability and the working life of mechanical seal, reduced maintenance cost.
For reaching the foregoing invention purpose, the technological scheme that the utility model adopted is: provide a kind of high damping new-type mortar mechanical seal for pump to comprise stationary ring and stationary seat at least; Said stationary ring is installed on the stationary seat; It is characterized in that: said stationary ring is provided with stationary ring vibration damping zero shape circle.
Preferably, said stationary ring and stationary seat contact jaw are provided with bulge loop.
Preferably, said stationary ring vibration damping zero shape circle is positioned on the bulge loop of stationary ring.
In sum, a kind of high damping new-type mortar mechanical seal for pump that the utility model provided makes stationary ring have certain nose balance function, has overcome the not tight influence of abrasive end face applying that vibration equipment brings; Improve the reliability and the working life of mechanical seal, reduced maintenance cost.
Description of drawings
Fig. 1 is a kind of high damping new-type mortar of the utility model mechanical seal for pump structural representation.
Wherein, 1, stationary ring; 101, bulge loop; 2, stationary ring zero shape circle; 3, rotating ring; 4, rubber corrugated pipe; 5, rotating seat; 6, snap ring; 7, spring; 8, spring seat; 9, stationary seat; 10, stationary ring vibration damping zero shape circle; 11, rotating ring packing ring; 12, bellows stiffening ring; 13, throw-out collar.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done detailed explanation.
As shown in Figure 1, this high damping new-type mortar mechanical seal for pump comprises stationary ring 1 and stationary seat 9 at least; Said stationary ring 1 is installed on the stationary seat 9; It is characterized in that: said stationary ring 1 is provided with stationary ring vibration damping zero shape circle 10.Said stationary ring 1 is provided with bulge loop 101 with stationary seat 9 contact jaws.Said stationary ring vibration damping zero shape circle 10 is positioned on the bulge loop 101 of stationary ring 1.
Rotating ring 3 right-hand members are sleeved in rubber corrugated pipe 4 left ends, and rotating seat 5 coats rotating ring 3 and rubber corrugated pipe 4 intersections; The shift fork transmission that rotating ring 3 leans on rotating seat 5 left ends, its left end contact with the right-hand member of stationary ring 1 and form friction pair, play the primary seal effect.
Rubber corrugated pipe 4 afterbodys (right-hand member) lean on interference fit to rotate with axle with snap ring 6, play the auxiliary seal effect; Snap ring 6 places between rubber corrugated pipe 4 and the rotating seat 5, leans on latch drive rotating seat 5 and rotating ring 3 to rotate with the axis together, plays gearing.
Rotating ring packing ring 11 places between rotating seat 5 and the rubber corrugated pipe 4, and rotating ring 3 is played the axially support effect; Bellows stiffening ring 12 places in the rubber corrugated pipe 4, and rubber corrugated pipe 4 is played a supportive role, and when preventing increased pressure, bellows is stepped on the limit; Throw-out collar 13 is enclosed within rotating seat 5 right-hand members, rotates with axle together with rotating seat 5; Spring 7 is contained on spring seat 8 and the throw-out collar 13, drives spring seat 8 and rotates with axle, and its left end contacts with rotating seat 5, to rotating ring 3 generations thrust left, redeeming.
In sum, a kind of high damping new-type mortar mechanical seal for pump that the utility model provided makes stationary ring have certain nose balance function, has overcome the not tight influence of abrasive end face applying that vibration equipment brings; Improve the reliability and the working life of mechanical seal, reduced maintenance cost.
Though describe in detail in conjunction with the embodiment of accompanying drawing, should not be construed as qualification to the protection domain of this patent to the utility model.In the described scope of claims, various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
