Description

technical field

[0001] The invention mainly relates to the field of centrifugal pumps and centrifugal fans, in particular to an impeller for centrifugal pumps and centrifugal fans. Background technique

[0002] Since the advent of centrifugal pumps and centrifugal fans, the structure of the impeller, the core component of its work, has been based on a hypothetical theoretical basis, which is to make the number of impeller blades infinitely large, and the thickness of the blades is infinitely small, thereby eliminating water in the impeller. The inner vortex can improve the working efficiency of the whole centrifugal pump to achieve the effect of energy saving. But in the actual structure, the number of blades of the impeller is very few, that is, under the effective volume of the overall design of the centrifugal pump, the number of blades is limited, and the blades also have a certain thickness. Because of the discrepancy between theory and reality, people have generally b...
