Abstract

The utility model provides a bearing body structure of a cylindrical multi-stage centrifugal pump. The bearing body structure of the cylindrical multi-stage centrifugal pump is characterized by comprising a first bearing body and a second bearing body, wherein the first bearing body and the second bearing body are connected in a whole circular mode. The connecting portion of the first bearing body and the second bearing body is located in the middle of a whole circle. According to the bearing body structure of the cylindrical multi-stage centrifugal pump, the bearing bodies are designed to be of a center-opened whole circular structure so that bearing components and a pump shaft sealing assembly can be disassembled, assembled and maintained conveniently. The reliable operation structural guarantee is offered when the cylindrical multi-stage centrifugal pump is operated under the working conditions of high rotary speed and heavy load.

Description

The bearing body structure of tubular multistage centrifugal pump
Technical field
The utility model belongs to the centrifugal pump field, is specifically related to a kind of bearing body structure of tubular multistage centrifugal pump.
Background technique
Centrifugal pump is flowing medium (gas and liquid, also can be the mixture of suspended particulate and gas or liquid) enter from blade rotor root (import), medium relies on the high speed rotating blade to obtain centrifugal force, produces a high pressure, from the medium transport equipment of pressure relief opening (outlet) outflow.Multistage centrifugal pump is that the plural pump that will have said function gathers together, on the fluid channel structure, the medium pressure relief opening that shows the first order communicates with the import of the second level, and the medium pressure relief opening of the second level communicates with the import of the third level, and so the mechanism of series connection has formed multistage centrifugal pump.The meaning of multistage centrifugal pump is to improve setting pressure.
Bearing support is the critical component in the tubular multistage centrifugal pump, and bearing support produces a large amount of heats when operation, needs in time cooling; But present bearing support cooling effect on the market is all not ideal enough, and this has directly affected the working life of bearing support.
The model utility content
The utility model provides the bearing body structure of the tubular multistage centrifugal pump of a kind of good cooling results, long service life for above-mentioned the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of bearing body structure of tubular multistage centrifugal pump is characterized in that, comprises clutch shaft bearing body and the second bearing support that full circle connects, and the connection part of clutch shaft bearing body and the second bearing support is in the neutral position of described full circle.
Further setting of the present utility model is, described clutch shaft bearing body and the second bearing support are pressure lubrication radial bearing body.
Further setting of the present utility model is, described clutch shaft bearing body and the second bearing support are the pressure lubrication thrust bearing body.
The bearing body structure of tubular multistage centrifugal pump described in the utility model can be so that dismounting and the maintenance of bearing part and shaft seal assembly by bearing support being designed to middle open type, completely circular structure.For the tubular multistage centrifugal pump moves under higher rotation speed, heavy load working condition, provide the structure of reliable operation to guarantee.
Description of drawings
Fig. 1 is first embodiment's of bearing body structure described in the utility model structural drawing;
Fig. 2 is second embodiment's structural drawing.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model provides a kind of bearing body structure of tubular multistage centrifugal pump, comprises clutch shaft bearing body 1 and the second bearing support 2 that full circle connects, and the connection part of clutch shaft bearing body 1 and the second bearing support 2 is in the neutral position of described full circle.Described clutch shaft bearing body 1 and the second bearing support 2 are pressure lubrication radial bearing body, clutch shaft bearing body 1 and the second bearing support 2 interior bearing shells 3 that all are equipped with.
Figure 2 shows that another embodiment of the present utility model, wherein clutch shaft bearing body 1 and the second bearing support 2 are the pressure lubrication thrust bearing body, are provided with plain thrust bearing 4, thrust disc 5, thrust disc nut 6 and bearing (ball) cover 7 in the bearing support.
The above is preferred embodiment of the present utility model, and all equivalent variations of doing according to the utility model claim all should belong to protection domain of the present utility model.
