Abstract
The utility model provides a novel electric submersible pump impeller, which belongs to the technical filed of pumps and resolves technical problems that the existing electric submersible pump impellers are easy to be worn, short in service life and the like. The novel electric submersible pump impeller comprises an impeller seat and blades fixedly connected to the impeller seat, wherein the blades are twisted blades, and the axial surface transversal at the inlet portion of each blade is a curve. The novel electric submersible pump impeller has the advantages of wear resistance, high workingefficiency, long service life and the like.
Description
Technical field
The utility model belongs to the pump technical field, relates to the impeller of a kind of Submerged Motor Pumps, particularly a kind of novel Submerged Motor Pumps.
Background technique
Impeller is the heart of Submerged Motor Pumps, and the quality of its performance directly influences the efficient of Submerged Motor Pumps.The outstanding problem foot efficient that existing Submerged Motor Pumps exists is not high, power consumption is big, easy to wear etc.Wherein, the Submerged Motor Pumps impeller is made up of wheel seat and wheel shaft, the impeller that uniform individual layer spirality water dumping blade is formed around wheel seat, and this individual layer blade can only play centrifugal water dumping effect, and pressure is low, venting quality is poor, and the angle of water dumping blade is provided with reasonable inadequately; And there is very big relation in the gap between its impeller and the volute when arranging on motor.
As Chinese patent (application number: 200520013485.4) disclose a kind of impeller, include front shroud, back shroud, wheel hub, between the described front and rear cover plate blade is installed, described wheel hub is connected with the pump shaft of centrifugal pump, it is characterized in that: described front shroud, the back shroud outside are respectively equipped with auxiliary blade.The blade of this patent adopts the cylinder blade, such impeller does not meet the rule of flow of fluid, and in use liquid is bigger to the impact force of impeller, the easy like this wearing and tearing that cause impeller, reduce the working efficiency of impeller, serious even working life that influence whole well usefulness Submerged Motor Pumps.
Summary of the invention
The purpose of this utility model is that the impeller at existing Submerged Motor Pumps exists above-mentioned problem, and the impeller of the novel Submerged Motor Pumps of a kind of more wear-resistant, longer service life, the diffusion of minimizing runner is provided.
The purpose of this utility model can realize by following technical proposal: a kind of impeller of novel Submerged Motor Pumps, comprise impeller base and the blade that is connected on the impeller base, it is characterized in that described blade is a distortion formula blade, described blade inlet part axial plane transversal is a curve.
The blade of the impeller of this novel Submerged Motor Pumps adopts distortion formula blade, make blade in the course of the work, the flowing law that meets liquid more, reduced the impact force of liquid to blade, the wearing and tearing of blade have effectively been controlled, improved the working efficiency of impeller, made the longer service life of well with Submerged Motor Pumps; Blade inlet part axial plane transversal is designed to curve, thereby increases inlet-duct area between blade, reduces the runner diffusion.
In the impeller of above-mentioned novel Submerged Motor Pumps, the described blade outside also is provided with impeller cover.
In the impeller of above-mentioned novel Submerged Motor Pumps, the described impeller cover outside also is provided with the impeller circle.
In the impeller of above-mentioned novel Submerged Motor Pumps, described impeller base sidepiece also is provided with the impeller fixed plate.Fix impeller by the impeller fixed plate.
In the impeller of above-mentioned novel Submerged Motor Pumps, described impeller base adopts stainless steel material to make.Impeller base adopts stainless steel material to make, and makes that impeller base is not easy to get rusty, thereby prolongs the working life of impeller.
Compared with prior art, the blade of the impeller of this novel Submerged Motor Pumps adopts distortion formula blade, the blade that makes in the course of the work, the flowing law that meets liquid more, reduced the impact force of liquid to blade, effectively controlled the wearing and tearing of blade, improved the working efficiency of impeller, made the longer service life of well with Submerged Motor Pumps; Blade inlet part axial plane transversal is designed to curve, thereby increases inlet-duct area between blade, reduces the runner diffusion.

Among the figure, 1, impeller base; 2, blade; 3, impeller cover; 4, impeller circle; 5, impeller fixed plate.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, the impeller of this novel Submerged Motor Pumps comprises impeller base 1 and the blade 2 that is connected on the impeller base 1, and this blade 2 is distortion formula blade 2, and blade 2 inlet part axial plane transversals are curve.
Blade 2 outsides of the impeller of this novel Submerged Motor Pumps also are provided with impeller cover 3, also are provided with impeller circle 4 in impeller cover 3 outsides, and impeller base 1 sidepiece also is provided with impeller fixed plate 5, fixes impeller by impeller fixed plate 5.Impeller base 1 adopts stainless steel material to make.Impeller base 1 adopts stainless steel material to make, and makes impeller base 1 be not easy to get rusty, thereby prolongs the working life of impeller.
The blade 2 of the impeller of this novel Submerged Motor Pumps adopts distortion formula blade 2, the blade 2 that makes in the course of the work, the flowing law that meets liquid more, reduced the impact force of liquid to blade 2, the wearing and tearing of blade 2 have effectively been controlled, improved the working efficiency of impeller, made the longer service life of well with Submerged Motor Pumps; Blade 2 inlet part axial plane transversals are designed to curve, thereby increase inlet-duct area between blade, reduce the runner diffusion.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used 1, impeller base morely; 2, blade; 3, impeller cover; 4, impeller circle; 5, term such as impeller fixed plate, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
