Abstract
The utility model relates to an impeller for an immersible pump. The impeller for a pump comprises a wheel seat and a supporting ring, and is characterized in that in the entry circumference of the impeller enclosed by the supporting ring, the wheel seat is provided with impeller blades; and an impeller outlet is arranged around the wheel seat below the impeller blades. The impeller for an immersible pump has the advantages that the well-use immersible pump of the mixed-flow impeller has high pump lift and large flow and can improve the efficiency by about 5 percent compared with the prior pump; and the startup of the pump can not cause threaded pipelines to loosen to result in the leakage of water pipes.
Description
Technical field
The utility model relates to a kind of impeller that uses in submersible pump.
Background technique
The structure of impeller is divided into four big classes: centrifugal four kinds of blade type (open type, enclosed), rotary flow type, flow channel type, (comprising single channel and double flow channel) spiral.Wherein blade impellers is easily manufactured, when resulting in blockage in the impeller, can clear up easily and keep in repair, but in long-time running, the gap of blade and pumping chamber madial wall is strengthened, thereby efficient is reduced.And the pressure reduction that adds on the conference destruction blade in gap distributes.Not only produce a large amount of eddy loss, and the axial force of pump is strengthened, simultaneously, because the gap is strengthened, the stability of the fluidised form of liquid is damaged in the runner, makes pump produce vibration, and head curve is more smooth.
Summary of the invention
The objective of the invention is to avoid the deficiencies in the prior art that a kind of impeller of pump is provided, simple in structure, flow is big, the lift height.
For achieving the above object, the technological scheme that the present invention takes is: a kind of impeller of pump, include wheel seat, and bracing ring, in the impeller inlet circumference that bracing ring surrounds, described wheel seat is provided with impeller blade; Below described impeller blade, be provided with impeller outlet around wheel seat.
Further, on described wheel seat, the center of impeller inlet is provided with the impeller center hole, and the inwall of impeller center hole is provided with keyway.
Further, described wheel seat and bracing ring are fixed with one.
The beneficial effects of the utility model are: the rotation of this impeller is adopted and is rotated counterclockwise, the well of this mixed-flow impeller submersible pump lift height, and flow is big, improves about 5% than existing pump efficiency.Pump can not make threaded passage loosening when starting, and causes pipe leakage.
Description of drawings
Fig. 1 is a schematic top plan view of the present utility model;
Fig. 2 is an AA cross-sectional schematic of the present utility model.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
As Fig. 1, shown in Figure 2, a kind of impeller of pump includes wheel seat 1, bracing ring 2, and in the circumference of the impeller inlet 3 that bracing ring 2 surrounds, described wheel seat 1 is provided with impeller blade 4; Below described impeller blade 4, be provided with impeller outlet 5 around wheel seat 1.On described wheel seat 1, the center of impeller inlet 3 is provided with impeller center hole 6, and the inwall of impeller center hole 6 is provided with keyway 7.Described wheel seat 1 is fixed with one with bracing ring 2.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (3)
