A high-efficiency lightweight impeller shaft

Abstract

The invention discloses an efficient and light impeller shaft, comprising fixed ends, connecting shafts, a principal shaft, connection fixing parts, stationary blades and reinforcing blades, wherein the connection fixing parts are arranged on two ends of the principal shaft and connected with the fixed ends through the connecting shafts; the stationary blades are slant fixed on the cylindrical surface of the principal shaft; one side, connected with the cylindrical surface of the principal shaft, of each stationary blade is provided with a mounting slot, the reinforcing blade body of each reinforcing blade is a fixed end, one side of each reinforcing blade body is provided with strip-shaped slots, one end of each reinforcing bade body is the fixed end, and the fixed end of each reinforcing blade body is inserted into the strip-shaped slots of the reinforcing blade body. The efficient and light impeller shaft body is still integrally formed, and each blade is welded with the reinforcing blade which is provided with strip-shaped slots therein and formed by the 3D printing technology, thereby, blade intensity can be ensued, and blade weight can also be greatly reduced; furthermore, the reinforcing blades are produced by using the 3D printing technology, so that the cost is relatively low.

Description

technical field [0001] The invention relates to the field of pump accessories, in particular to a high-efficiency and lightweight impeller shaft. Background technique [0002] Most of the runners of the water pumps currently used use impellers. During use, the blades on the impeller push the water to flow out. The lighter the blades of the impeller, the less affected by gravity, but because the flow of water itself is larger, Therefore, the impact on the impeller of the impeller is often greater, so the strength of the blade is extremely high, and the strength of the blade will be significantly lower after the blade is thinner, so there is a big contradiction between the two. With the continuous advancement of technology, 3D printing technology With the continuous maturity, 3D printing technology has been more and more used in the manufacturing industry. 3D printing technology can be used to make blades and make strip grooves inside the blades to reduce the quality of the bl...
