Abstract
The utility model discloses a desulfuration pump which comprises a pump body (1), a pump cover (2), a shaft (3), an impeller (4) and a mechanical seal, wherein the shaft end and the inner core of the impeller (4) are firmly connected; the mechanical seal consisting of a rotating ring (5), a stationary ring (6), a stationary ring seat (7), a spring (8) and a spring seat (9) is arranged between the pump cover (2) and the shaft (3); two spigots (10) are formed at one end of the spring seat (9) and two lug bosses (11) are formed at the other end thereof; the spring seat (9) and two lug bosses on the stationary ring seat (7) are positioned through the two spigots at one end of the spring seat (9); the stationary ring spring seat (6) and the two lug bosses (11) at the other end of the spring seat (9) are positioned through two spigots on the stationary ring (6); and the rotating ring (5) and the stationary ring (6) are in end surface contact. The utility model utilizing the traditional mechanical seal in a way that the stationary ring can work as the rotating ring and the rotating ring can work as the stationary ring, thereby improving leak-proof performance and sealing effect, and prolonging the service life of the mechanical seal.
Description
Technical field
The utility model relates to a kind of equipment for liquid transportation, particularly relates to a kind of desulfur pump.This pump is widely used in the flue gas desulfurization industry.
Background technique
As purifying coal-burning power plant's tail gas, absorb sulfur dioxide, reducing sulfur method--ammonia process or limestone--the gypsum wet type desulfurizing method that pollution of atmosphere is most widely used, need the desulfur pump of defeated slurries.Now be applied to the desulfur pump of this tooling, axially mechanical seal short, well damage in working life, and impeller increases the gap between impeller and the pump cover easily by chloride ion corrosion and wearing and tearing, has influenced the transfer efficiency of pump greatly.Not only require to have very strong corrosion resistance for desulfur pump, but also require to have excellent sealing performance.Existing desulfur 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 desulfur pump.
Summary of the invention
The purpose of this utility model provides a kind of desulfur pump, and it can solve the problem that at present domestic this class pump exists well.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises the pump housing, pump cover, axle, impeller and mechanical seal, axle head connects with the impeller inner core is fastening, mechanical seal be located at pump cover and and axle between, mechanical seal is by rotating ring, stationary ring, stationary seat, spring and spring seat are formed, one end of spring seat 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 by the boss location, two places of the two place's seams on it and the spring seat the other end, and rotating ring contacts with the stationary ring end face.
The flow passage components of the utility model desulfur pump adopt the two-phase stainless steel.
The said structure that the utility model adopts, with traditional mechanical sealing static ring do rotating ring, rotating ring is done stationary ring, owing to can improve the anti-leak performance, thereby has improved working life and sealing effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the utility model structural representation
Figure 2 shows that the be hit by a bullet structural representation of spring abutment of the utility model

Embodiment
By accompanying drawing as can be known, the utility model comprises the pump housing 1, pump cover 2, axle 3, impeller 4 and mechanical seal, axle head and fastening connection of impeller 4 inner cores, mechanical seal is located between pump cover 2 and the axle 3, mechanical seal is by rotating ring 5, stationary ring 6, stationary seat 7, spring 8 and spring seat 9 are formed, one end of spring seat 9 is provided with two place's seams 10, the other end is provided with two place's boss 11, spring seat 9 is by the boss location, two places of two place's seams 10 with the stationary seat 7 of an end, stationary ring 6 is by two place's boss, 11 location of the two place's seams on it and spring seat 9 the other ends, and rotating ring 5 contacts with stationary ring 6 end faces.Spring 8 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 superfine pressureless sintering silicon carbide of abrasion-proof corrosion-proof to make with extra care and form.The flow passage components of the utility model desulfur pump adopt the two-phase stainless steel, have improved corrosion resistant performance greatly.When desulfur 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 design and the flow passage components material of the utility model uniqueness are selected for use, and good sealing effect can improve the anti-leak performance, prolongs the working life of desulfur pump, and generally be 3-5 times of like product working life.
Claims (2)
1. desulfur pump, comprise the pump housing, pump cover, axle, impeller and mechanical seal, axle head connects with the impeller inner core is fastening, mechanical seal be located at pump cover and and axle between, it is characterized in that: mechanical seal is made up of rotating ring, stationary ring, stationary seat, spring and spring seat, one end of spring seat 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 by the boss location, two places of the two place's seams on it and the spring seat the other end, and rotating ring contacts with the stationary ring end face.
