Abstract
The utility model discloses a kind of Roots pump of good cooling results, comprise the pump housing, rotor, heat radiation sleeve and 2 seal rings; Described rotor is arranged in the endoporus of the pump housing; The circumferential outer surface of the described pump housing is provided with the circular groove of at least one axially-aligned, is provided with the curve bath of connection between described adjacent annular groove; Described radiating sleeve jacket casing is connected on the pump housing, and its axial two ends are tightly connected by seal ring and the pump housing, thereby makes circular groove and curve bath form the inner chamber of a retaining; The axial two ends of described heat radiation sleeve also include the water hole being communicated with inner chamber.The Roots pump good heat dissipation effect of good cooling results of the present utility model, long service life.
Description
Technical field
The utility model belongs to Roots pump field, is specifically related to a kind of Roots pump of good cooling results.
Background technique
General Roots pump is in the time of work, thereby rotor can rotation at full speed make pump body produce high temperature, because pump body seals, so high temperature cannot discharge, not only can be to the rust cleaning melting layer of the pump housing, and also rotor can be burnt again, thus the whole service life of Roots pump reduced.
Model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model is the Roots pump that proposes a kind of good cooling results, thereby cannot discharge to solve high temperature in conventional art middle pump body the problem of damaging rotor and the pump housing.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of Roots pump of good cooling results, comprises the pump housing, rotor, heat radiation sleeve and 2 seal rings; Described rotor is arranged in the endoporus of the pump housing; The circumferential outer surface of the described pump housing is provided with the circular groove of at least one axially-aligned, is provided with the curve bath of connection between described adjacent annular groove; Described radiating sleeve jacket casing is connected on the pump housing, and its axial two ends are tightly connected by seal ring and the pump housing, thereby makes circular groove and curve bath form the inner chamber of a retaining; The axial two ends of described heat radiation sleeve also include the water hole being communicated with inner chamber.
The surface of described endoporus is provided with at least one annular radiating groove.
The material of the sleeve of described heat radiation sleeve is aluminum alloy.
The material of described seal ring is rubber.
On described water hole, be welded with water pipe adapter.
(3) beneficial effect
The Roots pump of good cooling results of the present utility model, by circular groove and curve bath being set at the circumferential outer surface of the pump housing, and the heat radiation sleeve of socket sealing, thereby form the inner chamber that cooling water is installed, therefore can dispel the heat to the pump housing, further pump housing inner side and rotor are reached to radiating effect too, prevent the rust cleaning melting layer of the pump housing and come off, therefore improved the whole service life of Roots pump.And inner chamber is provided with the water hole of water inlet structure and water flowing out structure, thereby can make cooling water circulation, provide cost savings.
Brief description of the drawings
The planimetric map of the Roots pump of Fig. 1 good cooling results of the present utility model;
Fig. 2 is the sectional view of A-A in Fig. 1;
Fig. 3 is the sectional view of B-B in Fig. 2;
In figure, 1 is that the pump housing, 2 is for rotor, 3 is for heat radiation sleeve, 4 is for seal ring, 5 is for endoporus, 6 is for circular groove, 7 is for curve bath, 8 is for water hole, 9 is for radiating groove, 10 is for water pipe adapter.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The Roots pump of a kind of good cooling results as shown in Figure 1-Figure 3, comprises the seal ring 4 of the pump housing 1, rotor 2,3 and 2 quality of rubber materials of heat radiation sleeve; Described rotor 2 is arranged in the endoporus 5 of the pump housing 1; The circumferential outer surface of the described pump housing 1 is provided with the circular groove 6 of at least one axially-aligned, is provided with the curve bath 7 of connection between described adjacent annular groove 6; Described heat radiation sleeve 6 is socketed on the pump housing 1, and its axial two ends are tightly connected by seal ring 4 and the pump housing 1, thereby make circular groove 6 and curve bath 7 form the inner chamber of a retaining; So can hold cooling liquid, cooling liquid is lowered the temperature to the pump housing 1, prevent that it from removing rusty scale and getting rusty, and further make rotor burn out, thereby improved the radiating effect of Roots pump entirety, extend its working life.The axial two ends of described heat radiation sleeve also include the water hole 8 being communicated with inner chamber, on described water hole 8, are welded with water pipe adapter 10, by water pipe adapter 10, cooling liquid be passed in and out in energy inner chamber.By a water pump structure, thus the circulation of formation cooling liquid, therefore operation is very easy.
The surface of described endoporus 5 is provided with at least one annular radiating groove 9, by radiating groove 9, thereby strengthened the area of contact of high temperature and the pump housing 1 in the pump housing, thereby improved radiating effect.
The material of the sleeve of described heat radiation sleeve 3 is aluminum alloy, and aluminum alloy material good heat dissipation effect, when high temperature is cooling by cooling liquid, is discharged to the external world by heat radiation sleeve 3 simultaneously, has therefore improved radiating effect.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
