Abstract
The utility model discloses a bearing body water cooling structure for a horizontal multiple-stage centrifugal pump, comprising a water inlet (1), a bearing (2), a whole bracket (3), a bearing room (4), a water outlet (5) and a hole-free end cover (6). The bearing body water cooling structure is characterized in that the whole bracket (3) is symmetrically distributed with the water inlet (1) and the water outlet (5); the bearing room (4) is arranged on the side end face of the whole bracket (3) and the bearing room (4) is tightly contacted with the side face of the hole-free end cover (6); the bearing (2) is mounted in the whole bracket (3); the water inlet (1) is communicated with the bearing room (4); and the water outlet (5) is communicated with the bearing room (4). The utility model aims to provide a water cooling structure which has a simple structure and can reduce the heating amount of the bearing in a working process in a heat transferring manner.
Description
Technical field
The utility model relates to bearing constituent field, relates in particular to a kind of bearing support water-cooling structure that is used for horizontal multi-stage centrifugal pump.
Background technique
Horizontal type multi-stage pump often uses in coal mine, is mainly used in main draining.Because existing horizontal type multi-stage pump bearing support structure major defect is: bearing heating, influence working life, can cause frequent going to change bearing, tightly do not change difficulty, also wasted certain cost.The tradition horizontal type multi-stage pump does not have to be directed against the cooling system of bearing specially, thereby causes the bearing premature failure.Large pump particularly, going down to change bearing in coal mine is one and trouble, the thing of difficulty again, thus the technical problem that solves horizontal type multi-stage pump inner bearing premature failure is with extremely urgent.
The model utility content
The utility model is exactly in order to solve existing heating problem, and it is a kind of simple in structure that its purpose is to provide, and the mode through the heat transmission reduces the bearing water-cooling structure of heating value in the course of the work.
For realizing above purpose; The technological scheme that the utility model adopts is: a kind of bearing support water-cooling structure that is used for horizontal multi-stage centrifugal pump, and it comprises water inlet (1), bearing (2), integral support (3), bearing chamber (4), osculum (5) and atresia end cap (6); It is characterized in that: on integral support (3), be symmetrically distributed with water inlet (1) and osculum (5), the side end face of described integral support (3) offers bearing chamber (4), and bearing chamber (4) is adjacent to the side of atresia end cap (6); Bearing (2) is installed in the integral support (3); Described water inlet (1) is communicated with bearing chamber (4), and described osculum (5) also is communicated with bearing chamber (4).
In this article, described bearing chamber (4) is a ring.
The beneficial effect of the utility model: the utility model horizontal type multi-stage pump bearing support water-cooling structure; On the basis of existing technology; The utility model improves bearing support, and increases a bearing chamber, thereby has obtained the horizontal type multi-stage pump bearing support water-cooling structure device of the utility model; Solved in the bearing working process and generated heat, and the worry that causes bearing to lose efficacy in advance.Generally on big flow model pump, adopt such structure, the size of general bearing is also bigger, is on technical matters, to realize having higher economic value easily so use this cooling structure.The horizontal type multi-stage pump bearing support water-cooling structure of the utility model; Passed through experiment, at D150-100 (P); D680-100 (P) after long-time the use, proves that reliability is very high on the D800-100 multistage pumps such as (P); Cooling effect is very good in real work, thoroughly solves the high problem of bearing temperature.
Description of drawings
Fig. 1 is the erection drawing of the utility model.
Water inlet in the drawings, 1; 2, bearing; 3, integral support; 4, bearing chamber; 5, osculum; 6, atresia end cap.
Embodiment
As shown in Figure 1, the assembly relation of the utility model is: on integral support 3, be symmetrically distributed with water inlet 1 and osculum 5, the side end face of described integral support 3 offers bearing chamber 4, and bearing chamber 4 is adjacent to the side of atresia end cap 6; Bearing 2 is installed in the integral support 3; Described water inlet 1 is communicated with bearing chamber 4, and described osculum 5 also is communicated with bearing chamber 4.
When the pump high speed rotating, the temperature of bearing 2 can raise gradually, and bearing 2 is burnt out.Large pump particularly, going down to change bearing in coal mine is one and trouble, the thing of difficulty again.On the basis of existing technology, the utility model improves integral support 3, and increases a bearing chamber 4, and cooling water is 1 entering from the water inlet, and according to law of connected vessels, cooling water flows to bearing chamber 4, finally from osculum 5, and takes away the heat that bearing 2 produces.Thereby obtained the horizontal type multi-stage pump bearing support water-cooling structure device of the utility model, solved the worry of the heating of bearing 2, can increase the working life of bearing 2 greatly.
More than a kind of bearing support water-cooling structure that is used for horizontal multi-stage centrifugal pump that the utility model provided has been carried out detailed introduction; Principle and mode of execution to the utility model among this paper are set forth, and above embodiment's explanation just is used to help to understand the method and the core concept thereof of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on embodiment and application area, all can change, in sum, this description should not be construed as the restriction to the utility model.
Claims (2)
1. bearing support water-cooling structure that is used for horizontal multi-stage centrifugal pump, it comprises water inlet (1), bearing (2), integral support (3), bearing chamber (4), osculum (5) and atresia end cap (6); It is characterized in that: on integral support (3), be symmetrically distributed with water inlet (1) and osculum (5), the side end face of described integral support (3) offers bearing chamber (4), and bearing chamber (4) is adjacent to the side of atresia end cap (6); Bearing (2) is installed in the integral support (3); Described water inlet (1) is communicated with bearing chamber (4), and described osculum (5) also is communicated with bearing chamber (4).
