Axial flow pump blade based on bionics

Abstract

The invention aims to provide an axial flow pump blade based on bionics. The axial flow pump blade based on bionics is installed on an axial flow pump hub, the lower portion of the pump is connected with a fairing cap, and the axial flow pump blade comprises a blade top, a blade root, a blade root shaft and a blade body, wherein the blade body is the working part of the whole axial flow pump blade, the cross section of the blade body is provided with a structure provided with a protruding concave-convex front edge and a bionic coupled surface; the blade body is provided with a concave-convex front edge protruding structure protruding from the hub to one side of a blade tip, and the surface of the blade body has a bionic coupling function; the surface having the bionic coupling function isof a non-smooth structure, and the non-smooth structure is in a grooved shape; the grooved cross section is triangular. The axial flow pump blade can effectively and convectively control the flow ofa mass medium, prolong the service life of an axial flow pump impeller and has the important significance in stable operation and energy consumption reduction of an axial flow pump.

Description

technical field [0001] The invention relates to an axial flow pump blade, in particular to an axial flow pump blade based on bionics. Background technique [0002] At present, the axial flow pump has the characteristics of large flow and low head, and has a wide range of functions in agricultural irrigation and drainage, petrochemical industry, power industry, construction, urban water supply and drainage, nuclear power, thermal power generation, metallurgy and mining, and shipbuilding industry, but at the same time There are also problems such as huge energy loss, so it is of great significance to explore the measures to reduce energy consumption of axial flow pumps. After observation, it was found that the leading edge of the humpback whale's fin is protruding. This special fin structure can reduce the resistance of the water, so that the humpback whale has good underwater maneuverability. At the same time, it is also found that the grooved skin of the dolphin can buffer ...
