Problems solved by technology

Submerged chemical pumps are generally used to pump chemical media from tanks or pools. Various chemical media are often corrosive and contain solid particles, and the mechanical seal is easily damaged. The medium leaks into the bearing body, and the bearing is quickly damaged. The service life of the bearing is short, and the safety and reliability of the pump operation are poor

Description

[technical field] [0001] The invention relates to the technical field of submerged chemical pumps, in particular to an improved non-sealed submerged chemical pump. [Background technique] [0002] At present, the existing submerged chemical pumps all use rolling bearings, lubricated with grease or thin oil; the shaft seal is a mechanical seal. Submerged chemical pumps are generally used to pump chemical media from tanks or pools. Various chemical media are often corrosive and contain solid particles, and the mechanical seal is easily damaged. The medium leaks into the bearing body, and the bearing is quickly damaged. The service life of the bearing is short, and the safety and reliability of the pump operation are poor. [Content of the invention] [0003] The purpose of the present invention is to solve the above-mentioned deficiencies and provide an improved chemical pump. It mainly solves the technical problems in the following two aspects: one is that the pumping mediu...
