Problems solved by technology

[0007] Traditional chemical centrifugal pumps can only transport media with physical properties similar to water (without impurities and particles). Due to the unreasonable sealing structure, it is easy to be blocked due to high solid content of the medium, and it is easy to cause leakage due to wear and corrosion.

Abstract

The invention provides an anti-corrosive wearproof chemical centrifugal pump. The anti-corrosive wearproof chemical centrifugal pump comprises a pump body, an impeller nut, an impeller, a pump cover, a mechanical sealing set, a sealing box, a shaft sleeve, a carrier, a bearing gland, a bearing, a shaft and a suspension support. The pump body and the suspension support are connected with a base through bolts. The pump body is fixed to the carrier through bolts. The mechanical sealing set comprises a mechanical sealing moving ring and a mechanical sealing stationary ring. The mechanical sealing moving ring is arranged on the impeller. The pump cover, the sealing box and the mechanical sealing set are arranged on the pump shaft jointly. The pump cover is connected with the sealing box through bolts. The mechanical sealing stationary ring, a stationary ring seat and a spring are arranged between the pump cover and the sealing box. The shaft sleeve sleeves the shaft, and the bearing gland is connected to the carrier through bolts. The shaft is detachably connected with the carrier. The pump has the advantages of wide application range, long service life in sealing, wear resistance, corrosion resistance, no clogging and the like, and can be applicable to acid, alkali and / or salt media with any concentration and solid content smaller than or equal to 40%, wherein the hardness or softness degree of particles of the media is unlimited.

Description

[0001] technical field [0002] The invention relates to a pump, in particular to a corrosion-resistant and wear-resistant chemical centrifugal pump. Background technique [0003] Chemical centrifugal pumps are widely used in petroleum, chemical, metallurgy, pharmaceutical and other industries. At present, ordinary chemical centrifugal pumps used in the market can only transport media with physical properties similar to water (without impurities and particles). Leakage, increased noise, and significantly increased power loss. During maintenance, the shaft of the centrifugal pump must be taken out for reprocessing and new assembly to achieve the purpose of leak-proof and noise-proof. [0004] The structure of the traditional chemical centrifugal pump belongs to the prior art. For example, a chemical centrifugal pump is disclosed in the document CN202047988U, which consists of a mechanical seal static ring, a static ring seat, and a mechanical seal spring. It is characterized...
