The impeller of a centrifugal pump

Abstract

The invention relates to an impeller of a centrifugal pump. The impeller comprises a rotating turntable and blades, wherein a rotating shaft is arranged at the center of the rotating turntable; a water inlet is formed in the outer side of the rotating shaft; a water outlet is formed by the encircling of the two sets of blades adjacent to each other; each of the blades is composed of a first-level blade, a second-level blade, a third-level blade and a fourth-level blade; the second-level blades are arranged at the middle parts of the two sets of first-level blades adjacent to each other; the third-level blades are arranged at the middle parts of the first-level blade and the second-level blade; the fourth-level blades are arranged at the middle parts of the third-level blade and the second-level blade and at the middle parts of the third-level blade and the first-level blade; each set of blades is composed of a plurality of separating plates disconnected from each other; a water channel is formed between every two adjacent separating plates of each of the blades; the water channels respectively correspond to the separating plates of the blades on the two sides of the water channel. The impeller of the centrifugal pump has the advantages that the displacement is high, the positive and negative displacements are invariant, and the technical problems of discontinuous water drainage, light displacement and great reduction of negative draining efficiency of the present centrifugal pump are solved. For the prior art, the impeller has excellent market prospect and development space.

Description

technical field [0001] The invention relates to the field of centrifugal pumps, in particular to an impeller of a centrifugal pump. Background technique [0002] Centrifugal pump is a common centrifugal drainage equipment. The centrifugal pump first absorbs water in the pipeline, rotates out from the water inlet and enters between the blades, and then under the action of centrifugal force, the water is thrown from the center of the blade to the edge of the blade. Most of the existing centrifugal pumps are volute closed structure, the water outlet is set on the edge of the volute pump body, the water outlet direction is fixed to one side, and the drainage is performed intermittently during the rotation of the blades, and the drainage efficiency is low. , The curved structure of the blades leads to a greatly reduced drainage efficiency, and the drainage volume is small. How to design a centrifugal pump blade with reasonable structure, high displacement and high drainage effic...
