Problems solved by technology
[0002] In the process of conveying ceramic powder, not only a certain conveying pressure is required, but also the friction of ceramic powder is very large. If a volumetric pump such as a plunger pump is used for conveying, the steel sleeve is severely worn and has serious defects. Centrifugal pump conveying The pressure is unstable and cannot meet the requirements of ceramic powder transportation, and the wear of the metal impeller is also very serious. In view of this problem, it is necessary to design an elastic internal flow swirling constant pressure impeller structure to solve the above problems

Abstract
The invention discloses an elastomer internal-flow whirling constant-pressure impeller structure. The structure comprises a main body, main blades, auxiliary blades, a front side surface, a back sidesurface and a rubber body; a plurality of the main blades are arranged on one side of the main body; a plurality of the auxiliary blades are arranged on the other side of the main body; each main blade comprises a first straight blade and a second straight blade, an included angle formed by the first straight blade and the second straight blade is alpha, the ratio of the length of the first straight blade to the length of the second straight blade ranges from 0.68 to 1, and the outer edge of the second straight blade is an inclined side wall; the edge of the outer side of the main body is a straight side wall; the front side surfaces of the first straight blades and the front side surfaces of the second straight blades are inclined side wall surfaces; the back side surfaces of the first straight blades and the back side surfaces of the second straight blades are straight wall surfaces; the projection area of every two adjacent main blades on the main body is divided by the projection of one auxiliary blade on the main body into two parts with equal areas; and a mounting hole is formed in the center of the main body. The structure is simple, convenient to use, high in water conservation efficiency, few in produced vortex, constant in delivery pressure and capable of being widely popularized and applied.
Description
【Technical field】 [0001] The invention relates to the technical field of the impeller, in particular to the technical field of the internal flow swirl constant pressure impeller structure. 【Background technique】 [0002] In the process of conveying ceramic powder, not only a certain conveying pressure is required, but also the friction of ceramic powder is very large. If a volumetric pump such as a plunger pump is used for conveying, the steel sleeve is severely worn and has serious defects. Centrifugal pump conveying The pressure is unstable, which cannot meet the requirements of ceramic powder transportation, and the wear of the metal impeller is also very serious. In view of such problems, it is necessary to design an elastic internal flow swirling constant pressure impeller structure to solve the above problems. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose an elastic internal flow gyration c...
