Abstract

The invention discloses a symmetric double-outlet vortex chamber pump body of a vertical single-stage single-suction submerged centrifugal pump; the upper part of the pump body is provided with an upper flange; and two vortex chambers which are arranged horizontally and symmetrically are arranged in the pump body. The symmetric double-outlet vortex chamber pump body of the vertical single-stage single-suction submerged centrifugal pump has the characteristics that the structure is simple and the radial force can be maintained balanced under any working conditions, has the advantages that the efficiency is basically consistent, the high-efficiency scope is wide, the vibration is small, the service life of a sliding bearing is long, the strength of the pump body is better and the design thickness is a little smaller compared with a single-vortex chamber pump body, and further has the advantages that the casting is easy and an outlet diffusion tube is blocked more uneasily when the pump body with the small specifications is cast compared with a space guide vane-type pump body.

Description

The vertical single stage single suction submerged centrifugal pump symmetric double outlet volute chamber pump housing
Technical field
The invention belongs to the fluid conveying machine technical field, be specifically related to a kind of vertical single stage single suction submerged centrifugal pump symmetric double outlet volute chamber pump housing.
Background technique
The design of the traditional vertical one step single sucking submerged centrifugal pump pump housing mostly is the form of single outlet volute chamber form or spatial guide blade, single outlet volute chamber pump housing is under off-design behaviour, very large radial force is arranged, the efficient of the vertical submerged centrifugal pump of this pump housing and certain harmful effect is all arranged the working life of sliding bearing, and the pump body structure of spatial guide blade form is complicated, be not easy to cast and process, small dimension pump housing casting difficulty is large, and reject rate is high.
Summary of the invention
The object of the invention is to overcome above-mentioned not enough problem, a kind of vertical single stage single suction submerged centrifugal pump symmetric double outlet volute chamber pump housing is provided.
The technological scheme that the present invention adopts for achieving the above object is: the vertical single stage single suction submerged centrifugal pump symmetric double outlet volute chamber pump housing, pump housing top is provided with upper flange, is provided with the volute chamber that two horizontal symmetrical are arranged in the described pump housing.
Also comprise in the described pump housing and two two import diffusing tubes that are arranged symmetrically with that volute chamber is corresponding.
Described exit cone is Way out spirality straight up, and the entrance location of described exit cone is positioned at the end of its corresponding volute chamber, and the outlet of described exit cone is connected with the upper flange of the pump housing.
Characteristics of the present invention are: simple in structure, radial force can both keep balance under any operating mode; It is compared with single volute chamber pump housing: efficient is basically identical, and higher efficiency range is wide, vibrates littlely, and sliding bearing long service life, pump housing intensity are better than single volute chamber pump housing, and thickness can be slightly less than single volute chamber pump housing during design; Compare with the spatial guide blade form pump housing, casting easily, and during the casting small dimension pump housing, the more difficult obstruction of exit cone form.
Description of drawings
Fig. 1 is plan view of the present invention;
Fig. 2 is plan view of the present invention;
Fig. 3 is use schematic representation of the present invention.
Wherein: 1, upper flange 2, the pump housing 3, exit cone 4, volute chamber.
Embodiment
As Figure 1-3, the vertical single stage single suction submerged centrifugal pump symmetric double outlet volute chamber pump housing, the pump housing 2 tops are provided with upper flange 1, be provided with volute chamber 4 that two horizontal symmetrical arrange and two the import diffusing tubes 3 that are arranged symmetrically with corresponding with two volute chambers 4 in the described pump housing 2, described exit cone 3 is Way out spirality straight up, the entrance location of described exit cone 3 is positioned at the end of its corresponding volute chamber 4, the outlet of described exit cone 3 is connected with the upper flange 1 of the pump housing 2, the flow direction of the medium that impeller can be flowed out is changed into axial flow by radial flow, and the flow velocity of reduction liquid, increase the pressure energy of liquid, owing to be arranged symmetrically with because the volute chamber 4 of the pump housing 2 and exit cone 3 are, so its radial force can both keep balance under any operating mode.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technological scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
