Abstract
The utility model provides an electric submersible pump impeller with an improved structure, which belongs to the technical field of pumps and resolves technical problems that the existing electric submersible pump impellers are easy to be worn and short in service life and the like. The electric submersible pump impeller with an improved structure comprises an impeller seat and blades fixedly connected to the impeller seat, wherein the blades are twisted blades, the axial surface transversal at the inlet portion of each blade is a curve, and the outlet portion of each blade is in tangential oblique shape. The electric submersible pump impeller with an improved structure has the advantages of wear resistance, high working efficiency, long service life and the like.
Description
Technical field
The utility model belongs to the pump technical field, relates to a kind of Submerged Motor Pumps, particularly one one kinds of structure improved Submerged Motor Pumps impellers.
Background technique
At present, Submerged Motor Pumps mostly is made of motor and motor-driven pump housing two-part, and the pump housing comprises pump shaft, impeller.Its working principle is such: before the turn on pump, and must full of liquid in the suction pipe and the pump housing.Behind the turn on pump, impeller high speed rotating, liquid wherein, fly away from impeller and outwards penetrate under action of centrifugal force along with blade rotates together, and the liquid of ejaculation speed in the pump case explosion chamber is slack-off gradually, and pressure increases gradually, and then from pump discharge, discharge tube flows out.At this moment, in the blade center owing to liquid forms the vacuum low-pressure district that does not only have air but also do not have liquid around being thrown toward, liquid in the well is under the atmospheric effect of well face, in the suction pipe inflow pump, liquid comes to this and continuously is pumped up from well and continuously flows out from discharge tube.And impeller is the heart of Submerged Motor Pumps, and the quality of its performance directly influences the efficient of Submerged Motor Pumps.
As Chinese patent (application number: 200520018045.8) disclose a kind of water pump vane, the choma cover is enclosed within on the suction port of front shroud of impeller, back shroud of impeller is connected with spacer, be blade between front shroud of impeller and back shroud of impeller, it is characterized in that: tapered sleeve is positioned at spacer, and impeller nut is screwed on the spacer and with tapered sleeve and compresses contraction because of fixing on the pump shaft.The blade of the impeller of this patent adopts the cylinder blade, such impeller does not meet the rule of flow of fluid, 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 to have above-mentioned problem at existing well with the impeller of Submerged Motor Pumps, provide a kind of simple in structure, resistance is less, the structure improved Submerged Motor Pumps impeller of more wear-resistant, longer service life.
The purpose of this utility model can realize by following technical proposal: a kind of structure improved Submerged Motor Pumps impeller, 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, and the exit portion of blade is the shape of cutting sth. askew.
The blade of this structure improved Submerged Motor Pumps impeller 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, 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 a curve, and blade inlet part axial plane transversal is designed to curve, thereby increases inlet-duct area between blade, reduces the runner diffusion; The exit portion of blade is the shape of cutting sth. askew, the length difference of streamline before and after having reduced, thus reduced the secondary back that exports.
In above-mentioned structure improved Submerged Motor Pumps impeller, the described blade outside also is provided with impeller cover.
In above-mentioned structure improved Submerged Motor Pumps impeller, the described impeller cover outside also is provided with the impeller circle.
In above-mentioned structure improved Submerged Motor Pumps impeller, described impeller base sidepiece also is provided with the impeller fixed plate.Fix impeller by the impeller fixed plate.
In above-mentioned structure improved Submerged Motor Pumps impeller, 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 this structure improved Submerged Motor Pumps impeller 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.
