Abstract

The utility model discloses an impeller of a single-stage and double-suction centrifugal pump, and belongs to the field of centrifugal pumps. The impeller of the single-stage and double-suction centrifugal pump comprises a hub and a shaft disc, wherein the shaft disc is fixed in the middle of the hub, blade sets are arranged on the hub evenly in a spiral mode, and the thickness of the water inlet ends of the blade sets is smaller than that of the water outlet ends of the blade sets. According to the impeller of the single-stage and double-suction centrifugal pump, the large blades and the small blades are evenly arranged on the hub, the height of the small blades is smaller than that of the large blades, friction can be reduced when fluid flows in a flowing channel, internal losses are reduced, the efficiency of the centrifugal pump is improved, and the lift of the centrifugal pump is increased.

Description

A kind of single-stage double-suction centrifugal pump impeller
Technical field
The utility model relates to impeller, is specifically related to the impeller of single-stage double-suction centrifugal pump.
Background technique
The impeller of centrifugal pump can be divided into double shrouded wheel, half-opened impeller and unshrouded impeller.Impeller utilizes motor electric energy conversion to be become the kinetic energy of fluid, thereby makes fluid produce larger lift and flow velocity, and fluid transport is arrived special position.The water inlet of existing centrifugal pump impeller is young, and the resistance that fluid is subject in impeller is larger.The water intake of existing centrifugal pump impeller is less than water outlet, and the runner that is provided with between the same blade increases the frictional force between fluid, has reduced the working efficiency of centrifugal pump.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
The model utility content
The purpose of this utility model is to provide a kind of simple in structure, can improve the centrifugal pump working efficiency, increases the single-stage double-suction centrifugal pump impeller of lift.
For reaching above-mentioned purpose, the technological scheme that the utility model adopts is: a kind of single-stage double-suction centrifugal pump impeller is provided, comprises wheel hub and reel, reel is fixed in the middle part of wheel hub, and wheel hub is provided with vane group, and vane group is evenly distributed on wheel hub with helical.Vane group comprises large blade and small leaf, and the height of small leaf is lower than large blade height; Be provided with small leaf between adjacent large blade, be provided with large blade between adjacent small leaf, be provided with runner between adjacent large blade and small leaf.The top, two ends of large blade and small leaf is crooked in the opposite direction, and the height of large blade front-end and back-end is lower than the middle part height; Vane group feed-water end thickness is lower than waterexit end thickness.
Preferably, the two ends height of small leaf is lower than the middle part height.
Preferably, large blade has 4.
Preferably, the bend angle at large blade and small leaf two ends is identical.
In sum, the utility model advantage: evenly be provided with large blade and small leaf on wheel hub, the height of small leaf is lower than large blade, and the power of can reducing friction when fluid flows in runner has reduced internal loss, and the efficient of centrifugal pump is improved, and lift increases.
Description of drawings
Fig. 1 is the structural drawing that the utility model is installed large blade;
Fig. 2 is the arrange diagram of blade on wheel hub.
Wherein, 1, wheel hub; 2, reel; 3, large blade; 4, small leaf.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
The utility model provides a kind of single-stage double-suction centrifugal pump impeller, as shown in Figure 1, comprises wheel hub 1 and reel 2, and reel 2 is fixed on wheel hub 1 middle part, also is provided with axis hole and water intake on reel 2.Wheel hub 1 is provided with vane group, and vane group is evenly distributed on wheel hub 1 with helical.Vane group comprises large blade 3 and small leaf 4, and the height of small leaf 4 is lower than large blade 3 height.Be provided with small leaf 4 between adjacent large blade 3, be provided with large blade 3 between adjacent small leaf 4, be provided with runner between adjacent large blade 3 and small leaf 4.The top, two ends of large blade 3 and small leaf 4 is crooked in the opposite direction, and the height of large blade 3 front-end and back-end is lower than the middle part height; Vane group feed-water end thickness is lower than waterexit end thickness.The orientation of vane group on wheel hub has clockwise direction and counter clockwise direction; Two kinds of arrangement modes all belong to protection domain of the present utility model.
Preferably, the two ends height of small leaf 4 is lower than the middle part height.
Preferably, large blade 3 has 4.
Preferably, the bend angle at large blade 3 and small leaf 4 two ends is identical.
Although by reference to the accompanying drawings embodiment of the present utility model is described in detail, should not be construed as the restriction to the protection domain of this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
