Embodiment 1

[0047] Refer to attached Figure 1-6 As shown, an impeller for a vortex self-priming pump includes a bracket 1 and several blades 2, and the blades 2 are distributed on the bracket 1 in a circular array.

[0048] The bracket 1 includes an upper end 11, a middle end 12, and a lower end 13. The upper end 11 and the lower end 13 have the same size and are arranged concentrically with the middle end 12. The areas of the upper end 11 and the lower end 13 are smaller than the area of ​​the middle end 12, specifically the upper end 11 and the lower end. 13 is arranged symmetrically, and the upper end 11 and the lower end 13 are both flat, so that when connected to the main body of the water pump, a hard seal is formed to achieve a sealing effect.

[0049]Both the upper end 11 and the lower end 13 are provided with an annular cavity 14, the width of the annular cavity 14 accounts for one-fifth of the whole, and a through hole 15 is provided in the annular cavity 14, and the through ho...

Embodiment 2

[0058] Refer to attached Figure 7-8 As shown, a processing technology of the impeller for the vortex self-priming pump, including the impeller for the vortex self-priming pump, the specific structure of the impeller for the vortex self-priming pump has been described in detail in Embodiment 1, so it will not be added here repeat. The processing flow of the impeller for the vortex self-priming pump includes the following steps:

[0059] Step A: raw material processing Ⅰ: melt the injection molding raw materials and pour them into the mold of the bracket 1, and cool to form the bracket 1;

[0060] Step B: raw material processing II: placing the stainless steel plate under the punch press, and punching the blade 2 through the punch press;

[0061] Step C: Assembly: Fix the bracket 1 on the fixed frame, insert the blade into the gap of the bracket 1, and fix it with the bracket 1;

[0062] Step D: Grinding: Grinding the impeller with a grinding wheel to remove surface burrs; ...

Abstract

The invention discloses a vortex self-suction pump impeller and a processing technology thereof. The impeller comprises a bracket and a plurality of blades. The bracket comprises an upper end, a middle end and a lower end. The upper end and the lower end are the same size and concentrically arranged with the middle end. The upper end and the middle end are connected through a first connecting surface. The lower end and the middle end are connected through a second connecting surface; the middle end is provided with notches with a circumferential array distribution. A first clamping groove radial corresponding to the notches is arranged on the first connecting surface. The first clamping groove extends into the upper end. A second clamping groove radial corresponding to the notches is arranged on the second connecting surface. The second clamping groove extends into the lower end; the blade is provided with a first saw-tooth inverted hook and a second saw-tooth inverted hook; the firstsaw-tooth inverted hook and the second saw-tooth inverted hook are symmetrically arranged; the blades extend into the bracket through notches; the first saw-tooth inverted hook is clamped with the first clamping groove. The second saw-tooth inverted hook is clamped with the second clamping groove. A shaft sleeve is arranged in the bracket. The shaft sleeve and the bracket are made of plastic and are integrally formed; The impeller has the characteristics of simple structure, convenient installation, stably fixed blades and the like.

Description

technical field [0001] The invention relates to an impeller for a vortex self-priming pump and a processing technology. Background technique [0002] The impeller is widely used in water pumps. The impeller of the existing water pump includes a copper impeller body and several blades. The blades include an upper blade and a lower blade. The upper blade is fixed on the edge of the upper surface of the impeller body by welding, and the lower blade It is fixed on the lower surface of the impeller body by welding, and the positions of the upper and lower blades are corresponding. [0003] Due to the structural limitations of the impeller of the water pump in the prior art, its processing is extremely cumbersome (the upper and lower blades need to be welded to the two surfaces of the impeller body respectively). In addition, the position of the upper and lower blades is difficult to align during the welding process. Contents of the invention [0004] The technical problem mai...
