Abstract

The invention discloses a kind of vertical single stage single suction submerged centrifugal pump symmetric double symmetric double-outlet vortex 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.Feature of the present invention is: structure is simple, and radial force can keep balance under any operating mode; It is compared with single volute chamber pump housing: efficiency is basically identical, and higher efficiency range is wide, and vibrate little, sliding bearing long service life, pump housing intensity is better than single volute chamber pump housing, and during design, thickness can be slightly less than single volute chamber pump housing; Compare with the spatial guide blade form pump housing, casting is easy, and during the casting small dimension pump housing, the more difficult blocking of exit cone form.

Description

The vertical single stage single suction submerged centrifugal pump symmetric double symmetric double-outlet vortex chamber pump housing
Technical field
The invention belongs to fluid conveying machine technical field, be specifically related to a kind of vertical single stage single suction submerged centrifugal pump symmetric double symmetric double-outlet vortex 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 symmetric double-outlet vortex chamber form or spatial guide blade, single symmetric double-outlet vortex chamber pump housing is under off-design behaviour, there is very large radial force, the efficiency of the vertical submerged centrifugal pump of this pump housing and all have certain harmful effect the working life of sliding bearing, and the pump body structure of spatial guide blade form is complicated, be not easy to carry out casting and processing, 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 symmetric double-outlet vortex chamber pump housing is provided.
The technological scheme that the present invention is adopted for achieving the above object is: the vertical single stage single suction submerged centrifugal pump symmetric double symmetric double-outlet vortex chamber pump housing, and 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.
Two exit cones that are arranged symmetrically with corresponding with two volute chambers are also comprised in the described pump housing.
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 described outlet of exit cone is connected with the upper flange of the pump housing.
Feature of the present invention is: structure is simple, and radial force can keep balance under any operating mode; It is compared with single volute chamber pump housing: efficiency is basically identical, and higher efficiency range is wide, and vibrate little, sliding bearing long service life, pump housing intensity is better than single volute chamber pump housing, and during design, thickness can be slightly less than single volute chamber pump housing; Compare with the spatial guide blade form pump housing, casting is easy, and during the casting small dimension pump housing, the more difficult blocking of exit cone form.
Accompanying drawing explanation
Fig. 1 is plan view of the present invention;
Fig. 2 is plan view of the present invention;
Fig. 3 is use schematic diagram 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 symmetric double-outlet vortex chamber pump housing, the pump housing 2 top is provided with upper flange 1, the volute chamber 4 of two horizontal symmetrical layouts and two exit cones that are arranged symmetrically with 3 corresponding with two volute chambers 4 are provided with 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 changes into axial flow by radial flow, and reduce the flow velocity of liquid, increase the pressure energy of liquid, be arranged symmetrically with because the volute chamber 4 of the pump housing 2 and exit cone 3 are, therefore its radial force can keep balance under any operating mode.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technological scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
