Abstract
The invention discloses a desulphurization pump, which comprises a pump body shell, a pump body and a bracket, wherein a pump shaft is arranged in the bracket via a bearing; a skeleton oil seal A is respectively arranged in the rear cover of a right bearing on the pump shaft and in the front cover of a middle bearing; an impeller on the left end of the pump shaft is connected with the pump shaft via the inner core of the impeller; the right surface of the impeller is provided with a pump cover; a mechanical seal is arranged between the small diameter of the impeller and the pump cover; the mechanical seal consists of a static ring seat, a spring seat, a mechanical seal static ring, a mechanical seal movable ring and a spring; the right surface of the mechanical seal movable ring is successively provided with the mechanical seal static ring, the spring seat and the spring; and the outer circle of the mechanical seal static ring is provided with a static ring seat. According to the desulphurization pump disclosed by the invention, the traditional mechanical seal static ring is used as the movable ring, and the movable ring is used as the static ring, so the leak-proof performance is improved, and the service life and the sealing effect are improved.
Description
Technical field
The present invention relates to pump, particularly relate to a kind of desulfur pump that is used for the flue gas desulfurization industry.
Background technique
As purifying coal-burning power plant's tail gas, absorb sulfur dioxide, reducing sulfur method one ammonia process or limestone one 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 one will leak its mechanical seal device 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 invention is to provide a kind of rational in infrastructurely, can improve the desulfur pump of working life and sealability.
The present invention is achieved in that a kind of desulfur pump, comprises pump housing shell, the pump housing, carriage, it is characterized in that: be provided with pump shaft by bearing in the described carriage, be provided with outside framework oil seal A in the right bearing bonnet and the middle part bearing protecgulum on the pump shaft; Pump shaft left end impeller is connected with pump shaft by the impeller inner core, and the impeller right side is provided with pump cover, is provided with mechanical seal between impeller minor diameter place and the pump cover, and mechanical seal is made up of stationary seat, spring seat, mechanical sealing static ring, mechanical sealing linkage ring, spring; The mechanical sealing linkage ring right side is disposed with mechanical sealing static ring, spring seat and spring, and the mechanical sealing static ring outer ring is provided with stationary seat.
The present invention with traditional mechanical sealing static ring do rotating ring, rotating ring is done stationary ring, has improved the anti-leak performance, has improved working life and sealing effect.
