For water lifting of high-rise buildings, the higher the height is, the higher the lift of the pump is, the higher the power is, the impeller of the conventional submersible pump is conveyed by high-speed rotation of the blades, a certain auxiliary supporting structure is lacked on the blades, particularly, the higher the pressure borne by the impeller in high-lift application is, the impeller blades are deformed or even damaged when reaching a certain degree, and the normal use of the submersible pump is influenced.

Disclosure of Invention

The utility model aims at the above-mentioned problem that exists among the prior art, provide one kind and improved the well submersible pump impeller that makes it have high bearing performance and non-deformable to the monolithic stationary structure of blade.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a high bearing shape immersible pump impeller for well of preapring for an unfavorable turn of events, includes inner circle, bottom plate and main blade, its characterized in that, inner circle and bottom plate formula structure as an organic whole, the main blade weld in bottom plate surface center, circumference and even card are established and are fixed with round auxiliary blade on the outer wall of inner circle, auxiliary blade's outer lane is provided with the bearing ring, links firmly through the welding between auxiliary blade's outer tip and the bearing ring mutually.

This high technical effect who bears shape submersible pump impeller for well of preapring for an unfavorable turn of events does: for traditional impeller structure, the utility model discloses increased the round auxiliary vane on the outer wall of inner circle, this auxiliary vane on one side with inner circle welded fastening, on the other side with outside bearing ring welded fastening, increased its fixed stay structure to the length that has shortened main vane through setting up of auxiliary vane is equivalent to, makes its non-deformable, to sum up main vane length of this impeller structure shortens, and auxiliary vane's support fixed knot structure increases, and holistic bearing effect is showing and is improving, and wherein the pump shaft through the bottom plate center drives rotatoryly, and the cooperation through main auxiliary vane makes by inspiratory liquid get rid of and increases kinetic energy to immersible pump spiral shell inner wall and is got rid of, and the bearing ring is installed through the bearing cooperation of ball groove directness on with the pump head, prevents the whole slope of impeller, has also played certain supporting role and has made the impeller operation more stable.

In the high-bearing deformation-preventing submersible pump impeller for the well, the center of the outer ring of the bearing ring is provided with a ball groove.

In the impeller of the high-bearing deformation-preventing submersible pump for the well, the bearing ring is positioned above the inner ring.

In the submersible pump impeller for the high-bearing deformation-preventing well, the auxiliary blades and the outer wall of the inner ring are further fixed by welding.

In the submersible pump impeller for the high-bearing deformation-preventing well, the central axial direction of the bottom plate is provided with a pump shaft for transmission.

Compared with the prior art, this high bearing anti-deformation submersible pump impeller for well is through shortening the length of main blade to increase vice blade at inner circle outer wall, the bearing ring of rethread vice blade outer lane and pump head inner bearing fixed mounting make it have the high advantage of bearing non-deformable.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and 2, the submersible pump impeller for the high-bearing deformation-prevention well comprises an inner ring 1, a bottom plate 2 and main blades 3, wherein the inner ring 1 and the bottom plate 2 are of an integrated structure, the main blades 3 are welded at the center of the outer surface of the bottom plate 2, a circle of auxiliary blades 4 are circumferentially and uniformly clamped on the outer wall of the inner ring 1, a bearing ring 5 is arranged on the outer ring of each auxiliary blade 4, and the outer end parts of the auxiliary blades 4 are fixedly connected with the bearing ring 5 through welding.

In a further detail, the center of the outer ring of the bearing ring 5 is provided with a ball groove 6, and the ball groove 6 is used for movably connecting the whole impeller with the inner bearing of the pump head, so that the impeller is prevented from inclining during rotation, and the stability of the whole operation of the impeller is improved.

Furthermore, a bearing ring 5 is positioned above the inner ring 1, and the structure is used for increasing the contact area of the auxiliary blade 4 and the outside, so that liquid thrown out by the auxiliary blade 4 can be thrown to the inner wall of the volute.

Furthermore, the auxiliary blade 4 and the outer wall of the inner ring 1 are further fixed by welding due to the fact that the clamping only plays a certain fixing effect, overall fastening performance is improved, and the impeller is not prone to loosening.

Further, a pump shaft 7 for transmission is axially arranged at the center of the bottom plate 2, and the pump shaft 7 is connected with a motor shaft to realize transmission of torque force so as to drive the impeller to rotate.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.

Although the terms inner ring 1, bottom plate 2, main blade 3, secondary blade 4, bearing ring 5, ball groove 6, pump shaft 7, etc. are used more often herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed in a manner that is inconsistent with the spirit of the invention.
