Abstract
The utility model discloses a kind of axial subdivision two end supports Multistage centrifugal pump interstage flow distribution plate, it is characterized in that opening in the pump housing in the deep gouge on face, be screwed and the good flow distribution plate of independent manufacturing is installed.Owing to having installed the flow distribution plate processed in advance in the deep gouge of the pump housing, eliminate the spiral motion (prewhirling) that fluid produces in transition runner, relatively improve pump efficiency; Meanwhile, reduce the difficulty manufactured, easy for installation, improve production work efficiency.
Description
One, technical field
The utility model relates to mechanical engineering pump class technical field, specifically a kind of axial subdivision two end supports Multistage centrifugal pump interstage flow distribution plate.
Two, background technique
The part producing producer of current China axial subdivision two end supports multistage centrifugal pump does not arrange manifold structure, can allow fluid in transition runner, produce spiral motion (prewhirling) like this and directly enter next stage impeller, can cause harmful effect to pump performance; The inter-stage flow distribution plate also having the manufacturer of part to arrange adopts and is connected with the form of cast or weld with the part such as the choma of pump, but this structure to cast and processing bring great difficulty, can cause the decline of workman's working efficiency again.
Three, summary of the invention
In order to solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of processing, axial subdivision two end supports Multistage centrifugal pump interstage flow distribution plate easy for installation.
The technological scheme realizing the purpose of this utility model employing is: open in the pump housing in the deep gouge on face, be screwed and be provided with the good flow distribution plate of independent manufacturing.
The beneficial effects of the utility model are: owing to having installed the flow distribution plate processed in advance in the deep gouge of the pump housing, eliminate the spiral motion (prewhirling) that fluid produces in transition runner, relatively improve pump efficiency; Meanwhile, reduce the difficulty manufactured, easy for installation, improve production work efficiency.
Four, accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation that axial subdivision two end supports multistage centrifugal pump of the present utility model removes upper shell.
Fig. 2 is the partial enlarged drawing at I place in Fig. 1.
Fig. 3 is the A-A cross-section structure connection diagram of Fig. 2.
In figure: 1. the pump housing, 2. screw, 3. flow distribution plate.
Five, embodiment
In the accompanying drawings, axial subdivision two end supports Multistage centrifugal pump interstage flow distribution plate of the present utility model, is characterized in that opening in the pump housing 1 in the deep gouge on face, is installed with the good flow distribution plate of independent manufacturing 3 with screw 2.That flow distribution plate place is installed in dashed rectangle in Fig. 1.
Owing to opening deep gouge on face in the pump housing, flow distribution plate is installed, before fluid enters next stage impeller, eliminate its spiral motion produced in transition runner (prewhirling), improve pump efficiency, and structure is simple, is easy to manufacturing and installation.
