Abstract
The utility model relates to a high-efficiency energy-saving water pump which comprises a motor, a pump body and an impeller, wherein the front half part of the upstream face of the blade of the impeller is provided with uniformly-distributed spherical grooves; and the spherical depths of the spherical grooves occupy a quarter to one third of spherical diameters. According to the utility model, because the upstream face of the blade of the impeller is provided with the spherical grooves, water generates multiple rotational flow bodies in the spherical grooves, and the rotational flow bodies are thrown out of the impeller at a high speed through centrifugal force so that the centrifugal force of the water is increased, thus the delivery lift is increased by 10-20 percent, and the noises are lowered by 5 percent and 20 percent.
Description
Technical field
The utility model relates to a kind of water pump, particularly relates to a kind of energy-efficient water pump.
Background technique
Water pump commonly used carries out pump water by centrifugal force, because the upstream face of impeller is smooth surface, is difficult to improve the lift of water pump.
Summary of the invention
The purpose of this utility model just provides a kind of energy-efficient water pump, can improve lift, and can reduce noise.
For achieving the above object, the utility model adopts following technological scheme:
A kind of energy-efficient water pump comprises: motor, the pump housing, impeller, the front half part of the blade upstream face of described impeller is provided with uniform rounded channels, the sphere degree of depth of described rounded channels account for spherical diameter 1/4th to 1/3rd between.
The notch place of described rounded channels is provided with fillet.
Described rounded channels is the upstream face that geosynclinal concave enters impeller blade, and recessed portion is the part of sphere curved surface.
The beneficial effects of the utility model: because the upstream face of impeller blade is provided with rounded channels, water produces numerous rotary fluids and by the centrifugal force impeller of dishing out at a high speed, water centrifugal force is increased in rounded channels, can improve lift 10%-20%, and noise also decreases, and is reduced between 5% to 20%.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model impeller part.
Fig. 2 is the front schematic view of Fig. 1.
Fig. 3 is the local enlarged diagram at the A place of Fig. 2.
Embodiment
As shown in Figure 1 to Figure 3, the utility model comprises: comprising: motor, the pump housing, impeller 1, the front half part of blade 3 upstream faces of described impeller is provided with uniform rounded channels 2, described rounded channels is that a lot of rounded channels are distributed on the face of blade, the first half of upstream face refers to the forward part in the blade outside, as shown in Figure 1.
The sphere degree of depth of described rounded channels (i.e. depression the degree of depth) account for spherical diameter 1/4th to 1/3rd between.The notch place of described rounded channels is provided with fillet 21.Described rounded channels is the upstream face that geosynclinal concave enters impeller, and recessed portion is the part of sphere curved surface.
Claims (2)
