Embodiment Construction

[0022] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0023] Such as figure 1 As shown, the impeller of the vortex air pump includes a disc-shaped hub 1 and a number of blades 2 uniformly fixed on the outer circumference of the hub 1, and a ring-shaped partition plate 3 extends radially from the outer circumference of the hub 1. The blades 2 are distributed symmetrically along the partition plate 3 left and right and the blades 2 on the left and right sides are staggered at intervals. The hub 1, the blade 2 and the partition plate 3 are integrally formed by casting, which improves the strength of the overall structure.

[0024] Specifically, if figure 2 , image 3 , Figure 4 As shown, the blade 2 in this embodiment is in the shape of a rectangular sheet and the blade 2 ...

Abstract

The invention provides an impeller of a vortex air pump, belongs to the technical field of air pumps, and solves the problems that left and right blades of the conventional impeller are arranged symmetrically to influence dynamic balance, burrs are difficult to remove in the manufacturing processing procedure, and the like. The impeller for the vortex air pump comprises a disc-shaped hub and a plurality of blades which are uniformly and fixedly connected to the outer circumference edge of the hub, wherein an annular division board radially stretches out of the outer circumference of the hub; and the blades are distributed in a eudipleural mode along the division board, and the blades on left and right sides are staggered at intervals. The blades on the left and right sides are staggered at equal intervals, so that production difficulty is reduced, and the dynamic balance of the impeller is improved simultaneously.

Description

technical field [0001] The invention belongs to the technical field of air pumps, and relates to a vortex air pump, in particular to an impeller of the vortex air pump. Background technique [0002] The vortex air pump is a ventilation air source for both blowing and suction. It is also called a side channel fan, a regenerative pump, a ring blower or a gas ring compressor, etc. It can be used alone as a vacuum pump or a blower. , It is widely used in various fields such as pneumatic conveying system, vacuum lifting and clamping system, packaging machine, sewage plant ventilation, water treatment aeration, bagging / bottle / filling system, soil improvement, foam forming system, etc. The impeller of the vortex air pump is composed of dozens of blades, which is similar to the impeller of a huge gas turbine. The air in the middle of the impeller blades is subjected to centrifugal force and moves to the edge of the impeller, where the air enters the annular cavity of the pump body ...
