Problems solved by technology

[0002] At present, the process pumps widely used in the petrochemical industry have many unreasonable design points. In the actual production and use process, the pumps tend to generate overall vibration and relatively large noise. The installed bearings are often due to insufficient force These problems seriously affect the normal service life of the pump. At the same time, the sealing of the pump is not good, which is easy to cause environmental pollution, so it is increasingly unable to meet the needs of production.

Abstract

The invention discloses a process pump. The process pump comprises a pump body, a pump cover, a spindle and an impeller, wherein the impeller is mounted in the pump body, the pump cover covers the pump body, the front section of the spindle penetrates the pump cover to be arranged in the pump body, the rear section of the spindle is located outside the pump body, the impeller is fixed on the front section of the spindle, the rear section of the spindle is fixed in a bearing suspension part, a pump body sealing ring is arranged on the pump body inner wall at a position where the pump body and the impeller are close to each other, an impeller sealing ring is arranged at the impeller edge at the position where the pump body and the impeller are close to each other, and cartridge mechanical sealing is arranged at a position, close to the outer side of the pump cover, of the spindle. The process pump is long in service life, good in environmental protection performance and sealing performance and capable of satisfying production requirements.

Description

technical field [0001] The invention relates to a pump, in particular to a process pump. Background technique [0002] At present, the process pumps widely used in the petrochemical industry have many unreasonable design points. In the actual production and use process, the pumps tend to generate overall vibration and relatively large noise. The installed bearings are often due to insufficient force These problems seriously affect the normal service life of the pump. At the same time, the sealing of the pump is not good, which is easy to cause environmental pollution, so it is increasingly unable to meet the needs of production. Contents of the invention [0003] The technical problem solved by the present invention is to provide a process pump to solve the above-mentioned shortcomings in the background technology. [0004] The technical problem solved by the present invention adopts following technical scheme to realize: [0005] A process pump, including a pump body, a...
