Abstract

The utility model discloses a splint type corrosion-resistant wear-resistant mortar pump, comprising a pump body (1), a pump cover (2), a shaft (3), a sealing box (3), an impeller (5) and a mechanical sealing device. The mechanical sealing device consists of a movable ring (6), a stationary ring (7), a stationary ring seat (8), a spring (9) and a spring seat (10); the spring seat (10) and two bosses of the stationary ring seat (8) are positioned by two bayonets (11) at one end of the spring seat (10); the stationary ring (7) is positioned with two bosses (12) at the other end of the spring seat (10) by the two bayonets thereof; the movable ring (6) is positioned with the impeller (5) by bayonets thereof; and the friction surface of the movable ring (6) is contacted with the friction surface of the stationary ring (7). The mortar pump adopts the structure and can prolong the service life of the mortar pump due to the improvement of the leak-proof performance.

Description

Clamping plate type corrosion resistant abrasion-proof slurry pump
Technical field
The utility model relates to a kind of equipment for liquid transportation, especially relates to a kind of clamping plate type corrosion resistant abrasion-proof slurry pump.
Background technique
Mortar pump is a kind of equipment for liquid transportation, mainly comprises compositions such as the pump housing, axle, impeller and mechanical seal device.At present, mortar pump is widely used in every profession and trade, as carries acid, alkaline clear liquid or slip, the various sewage of various corrosive ore pulp of metallurgy industry and environmental protection industry (epi), not only require to have very strong corrosion resistance for mortar pump, but also require to have excellent sealing performance.Existing mortar pump is owing to the defective of structural design, and its mechanical seal device generally will leak under the negative pressure operating mode; In addition, along with the prolongation of pump operation time, the installation cooperation place of impeller and other component, particularly the impeller root also can leak, and has influenced the working life of mortar pump.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of clamping plate type corrosion resistant abrasion-proof slurry pump of anti-leak.
Technical problem to be solved in the utility model is achieved by the following technical solution: it comprises the pump housing, pump cover, axle, sealed case, impeller and mechanical seal device, mechanical seal device is located at pump cover, in the Seal cage that impeller and sealed case form, mechanical seal device is by rotating ring, stationary ring, stationary seat, spring and spring seat are formed, spring seat is located in the stationary seat, the one end is provided with two place's seams, the other end is provided with two place's boss, spring seat is by the boss location, two places of the two place's seams and the stationary seat of an end, stationary ring is located in the stationary seat, and locate by two place's seams on it and two place's boss of the spring seat the other end, rotating ring is by seam on it and impeller location, and the rotating ring rubbing surface contacts with the stationary ring rubbing surface.
Impeller outer described in the utility model surface is provided with fluoroplastics layer.
Spring described in the utility model surface is provided with the plastic-blasting layer.
The said structure that the utility model adopts, owing to can improve the anti-leak performance, thus prolonged the working life of mortar pump.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Figure 1 shows that structural representation of the present utility model
Figure 2 shows that the be hit by a bullet structural representation of spring abutment of the utility model
Figure 3 shows that the plan view of Fig. 2
Embodiment
By accompanying drawing as can be known, the utility model comprises the pump housing 1, pump cover 2, axle 3, sealed case 4, impeller 5 and mechanical seal device, mechanical seal device is located at pump cover 2, in the Seal cage that impeller 5 and sealed case 4 form, mechanical seal device is by rotating ring 6, stationary ring 7, stationary seat 8, spring 9 and spring seat 10 are formed, spring seat 10 is located in the stationary seat 8, the one end is provided with two place's seams 11, the other end is provided with two place's boss 12, spring seat 10 is by the boss location, two places of two place's seams 11 with the stationary seat 8 of an end, stationary ring 7 is located in the stationary seat 8, and locate by two place's seams on it and two place's boss 12 of spring seat 10 the other ends, rotating ring 6 is by seam on it and impeller 5 location, and rotating ring 6 rubbing surfaces contact with stationary ring 7 rubbing surfaces.Spring 9 also can be with other elastic compensating spare replacement, as long as axially producing elastic pressure, rotating ring is closely contacted with the rubbing surface of stationary ring.Rotating ring and stationary ring adopt the extremely strong pressureless sintering silicon carbide of abrasion-proof corrosion-proof to make with extra care and form.Described impeller 5 outer surfaces are provided with fluoroplastics layer 13, and fluoroplastics layer and impeller high-temperature high-pressure are made one, and fluoroplastics layer is distributed to the root of impeller always, make impeller not have leakage point up and down, can effectively prevent to leak.For improving the decay resistance of spring 9, the surface Machining of described spring 9 has the plastic-blasting layer.When mortar pump startup work, carry liquid to enter from the liquid entering hole of pump below, impeller is high speed rotating under the axle of high speed rotating drives, and the impeller of high speed rotating utilizes negative pressure will carry liquid to pump from the liquid outlet on the left side.The mechanical seal device of the utility model uniqueness and blade wheel structure design can improve the anti-leak performance, prolong the working life of mortar pump.
