Abstract
The utility model relates to an improved impeller of a self suction pump to overcome the problem of easy breaking of the roots of blades of existing products. The utility model is characterized in that the side edges of radiate blades which are in a radial direction are fixedly connected with rib rings, and the root of the blade is connected with a shaft sleeve; stress is dispersed by the reinforcing function of the rib rings. The blades can not break easily, and the service life of products is extended.
Description
The utility model belongs to pump technology, particularly the improvement of self-priming pump impeller.
The impeller of existing self-priming pump, blade is the radial radiation shape, a same Bevel shape on the top of each blade, root and axle sleeve are fixed into one.Its shortcoming has two: one, and when impeller radius was big, the moment that blade bears was bigger, and in use the normal blade that takes place in footpath is from the root phenomenon of rupture; The 2nd, can only unidirectionally turn round, if antiport efficient will obviously reduce.
The purpose of this utility model provides the not self-priming pump impeller of easy-rupturing of a kind of blade, and forward and reverse equal can normal operation.
The utility model impeller, blade are the radial radiation shape, and the root and the axle sleeve of each blade are fixed into one, it is characterized in that the side of gilled rings and each blade is connected; The blade two sides is all made identical plane.
The utility model since with each blade all with strengthen gilled rings and be connected, make the force bearing point dispersion, reduced concentrated stressed to root of blade, thereby solved the root of blade breakage problem, prolonged the working life of impeller and the service cycle of pump by a relatively large margin.Because identical plane shape is all made on the blade two sides, impeller clockwise and anticlockwise efficient is identical again, has overcome the problem of fixing a side that pump in the past can only be placed on power engine, can be placed on any side according to actual conditions.
In the accompanying drawing, Fig. 1 is a plan view of the present utility model, and Fig. 2 is that Figure 1A-A is to view.
Present embodiment adopts 20 blades 2 and axle sleeve 3 radially to be connected, and has omitted blade single face inclined-plane manufacturing procedure, press the sectional shape otch of gilled rings 1 in blade 2 upper ends one side, makes gilled rings 1 embedding blade 2.In actual fabrication, as long as the diameter of gilled rings 1 all can be realized the effect of strengthening rib greater than the diameter of axle sleeve 3.This impeller integral body can adopt casting or injection moulding once-through; To original impeller transformation of the way, gilled rings can be connected with sunk screw with the side of each blade.
Claims (2)
1, a kind of impeller of self-priming pump, root of each blade (2) and axle sleeve (3) are connected and are the radial radiation shape, it is characterized in that gilled rings (1) and the side of each blade (2) are connected.
2, impeller according to claim 1 is characterized in that blade (2) two sides is the plane.
