Description

Technical Field

[0001] The utility model relates to the technical field of chemical centrifugal pump installation, in particular to a pump body installation structure for a chemical centrifugal pump and a chemical centrifugal pump. Background Technique

[0002] A chemical centrifugal pump refers to a centrifugal pump used in the chemical field. Compared with other types of pumps, it has the advantages of simple structure, not easy to wear, stable operation, low noise, uniform water output, convenient adjustment, high efficiency, etc. Therefore, chemical centrifugal pumps have been widely used. The working principle of a chemical centrifugal pump is that when the pump is filled with water, the impeller rotates to generate centrifugal force. The water in the impeller channel is thrown to the periphery under the action of centrifugal force and flows into the pump shell. As a result, the pressure in the center of the impeller decreases, and this pressure is lower than the pressure in the water inlet pipe. The water then flows into the impeller from the suction pool under the action of this pressure difference. In this way, the water pump can continuously absorb water and supply water.

[0003] The existing pump body of a chemical centrifugal pump is a component of the chemical centrifugal pump. When installing a chemical centrifugal pump, a large number of bolts are used. As a result, when the user installs the pump body of the chemical centrifugal pump, a large amount of time will be wasted due to too many bolts. At the same time, after installation, it is not convenient to adjust its position according to the usage situation, reducing the applicable range.

[0004] Therefore, we invented a pump body installation structure for a chemical centrifugal pump and a chemical centrifugal pump. Content of the Utility Model
