Abstract
The utility model discloses an internal circulation cooling type submersible sewage pump which has a good cooling effect and operates reliably. The sewage pump comprises a pump body, a stator in the pump body and a rotor in the middle of the stator, wherein the periphery of the pump body is provided with a cooling device, and the cooling device consists of a cooling impeller arranged on the rotor, a heat exchange tank arranged under the cooling impeller, a water inlet pipe and a water return pipe. The utility model is applicable to a submersible sewage pump.
Description
Technical field
The utility model relates to a kind of proof submersible sand discharging pump, relates in particular to hydronic proof submersible sand discharging pump in a kind of employing.
Background technique
The type of cooling of traditional submersible sewage pump motor adopts direct cooling type, be that motor housing adopts heat radiating fin structure, this structure is mainly used in the water pump of middle low power, and more powerful proof submersible sand discharging pump adopts the jacketed type type of cooling, cooling medium mainly uses sewage, the employing mechanical water is also arranged, but the sewage medium often appears in the effluent cycle jacketed type type of cooling to be stopped up in the cooling channel, phenomenons such as slagging scorification, easily cause the motor cooling insufficient, the motor overtemperature, serious consequences such as burn-down of electric motor are not though the mechanical water jacketed type type of cooling exists the sewage medium to stop up, the slagging scorification phenomenon, but also have mechanical water heating swelling, can cause mechanical seal to lose efficacy like this, the motor damage of leaking exists cooling insufficient simultaneously, the motor feels hot, even problem such as damage.Install for the water pump dry type especially, situation is particularly serious, can not satisfy the requirement of safe operation at all.
The model utility content
The technical problems to be solved in the utility model provides a kind of have good cooling results, reliable interior circulation cooling type proof submersible sand discharging pump.
In order to address the above problem, the utility model is solved by the following technical programs:
The utility model comprises the stator in the pump housing, the pump housing, the rotor in the middle of the stator, and described pump housing periphery is provided with cooling unit, and described cooling unit is made up of heat exchange groove, intake pipe and the return pipe of being located at epitrochanterian cooling wheel, cooling wheel below.
As preferably, described heat exchange groove is made up of equally distributed radially radiating fin on cell body, the cell body, forms cooling passage between the described adjacent radiating fin.
The utility model compared with prior art has following obvious advantage and good effect:
1, good cooling results.Because the utility model adopts the cooling unit that has the heat exchange groove, circulation form in adopting has effectively improved cooling effect.
2, reliable.Because the utility model adopts closed interior circulation methods for cooling, can effectively avoid cooling medium to stop up phenomenons such as cooling channel, slagging scorification, thereby improve operational reliability.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of heat exchange groove among Fig. 1;
Fig. 3 be among Fig. 2 A-A to cut-away view.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Figure 3: the utility model comprises the stator 2 in the pump housing 1, the pump housing 1, the rotor 3 in the middle of the stator 2, the pump housing 1 periphery is provided with cooling unit, cooling unit by be located at the cooling wheel 4 on the rotor 3, heat exchange groove 5, intake pipe 6 and the return pipe 7 of cooling wheel 4 belows formed, wherein heat exchange groove 5 is made up of equally distributed radially radiating fin 9 on cell body 8, the cell body 8, forms cooling passage 10 between the adjacent radiating fin 9.
During the utility model work, cooling wheel 4 and rotor 3 run-in synchronisms, so around cooling liquid is transported to stator 2 from intake pipe 6, flow to cooling wheel 4 imports again by return pipe 7 then, the realization liquid circulation flows, thereby the heat that produces when making machine operation is brought heat exchange groove 5 into by cooling liquid, and is dispersed into by main impeller 20 in the sewage medium of conveying.
Claims (2)
1. circulation cooling type proof submersible sand discharging pump in a kind, comprise the stator in the pump housing, the pump housing, the rotor in the middle of the stator, it is characterized in that described pump housing periphery is provided with cooling unit, described cooling unit is made up of heat exchange groove, intake pipe and the return pipe of being located at epitrochanterian cooling wheel, cooling wheel below.
2. circulation cooling type proof submersible sand discharging pump in according to claim 1 is characterized in that described heat exchange groove is made up of equally distributed radially radiating fin on cell body, the cell body, forms cooling passage between the described adjacent radiating fin.
