Abstract
The utility model discloses a jet self-priming pump, mainly comprising two parts, namely, a pump and a motor, wherein the motor part mainly comprises a machine barrel, a stator and a rotor; the stator and the rotor are arranged inside the machine barrel; the outer wall of the stator is connected with the inner wall of the machine barrel in a full-area contact manner. Compared with an existing jet self-priming pump, the jet self-priming pump has the characteristics of being good in cooling performance, safe to transport liquid and free of pollution.
Description
Technical field
The utility model relates to self-absorption electric pump, is specially a kind of jet-type self-absorption electric pump.
Background technique
Jet-type self-absorption electric pump mainly comprises pump and motor two-part, and wherein pump part is mainly comprised of the pump housing, impeller, stator and liquid jetting device, and motor part is mainly comprised of machine barrel, stator and rotor.
At this, existing motor stator is that the some connecting tendons that arrange by machine tube inner wall carry out local positioning, not only join strength is not high, topmost problem is that the area of contact of stator and machine barrel is few and cause radiating efficiency poor, had a strong impact on the heat dispersion of motor, temperature rise while making machine operation is too fast, and excess Temperature, to having caused certain influence the working life of electric pump.
In addition, impeller in the existing pump housing, stator and liquid jetting device are all to adopt metal material, and not only cost is high, simultaneously because three directly contacts with carrying liquid, after long-time use, can there is corrosion and contaminated liquid, give actual use with certain potential safety hazard.
Model utility content
For the problems referred to above, the utility model has designed a kind of jet-type self-absorption electric pump, and it has perfect heat-dissipating, carries the feature of liquid safety non-pollution.
For achieving the above object, the utility model adopts technological scheme:
A self-absorption electric pump, mainly comprises pump and motor two-part, and wherein motor part is mainly comprised of machine barrel and the stator, the rotor that are arranged in machine barrel, it is characterized in that: described stator outer wall is connected with the contact of machine tube inner wall gross area.
Further, said pump part is mainly comprised of the pump housing, impeller, stator and liquid jetting device, and impeller wherein, stator and liquid jetting device all adopt plastic material.
Stator outer wall of the present utility model is that gross area contact is connected with machine tube inner wall, this structure arranges, compare the local Placement of existing connecting tendon, both area of contact of dispelling the heat of lifting that can be at double, and then can effectively promote the radiating efficiency between stator and machine barrel, compare the low 10K of electric machine temperature rise with similar electric pump, can effectively extend the working life of electric pump.
In addition, the impeller in pump part, stator and liquid jetting device are all adopted made of plastic, and not only cost economy, the more important thing is the generation of having stopped corrosion phenomena, avoid carrying liquid contaminated, guarantee to carry the Security of liquid.
Accompanying drawing explanation
Fig. 1, structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of jet-type self-absorption electric pump, mainly comprises pump 1 and motor 2 two-part.Wherein motor 2 parts are mainly comprised of machine barrel 21, stator 22, rotor 23, front cover 24, rear end cover 25, fan blade 26, fan housing 27; Pump 1 part is mainly comprised of the pump housing 11, impeller 12, stator 13, liquid jetting device 14, impeller 12 wherein is directly positioned on the output shaft 28 of described motor 2, the front end center inlet of impeller 12 is communicated with the water intake 111 on the pump housing 11 by liquid jetting device 14, and the outlet of impeller 12 edge is communicated with the water outlet 112 on the pump housing 11 by stator 13.
Described stator 22 outer walls are connected with machine barrel 21 inwall gross area contacts.This structure arranges, compare the local Placement of existing connecting tendon, both area of contact of dispelling the heat of lifting that can be at double, and then can effectively promote the radiating efficiency between stator 22 and machine barrel 21, the results showed, compare the low 10K of the utility model motor 2 temperature rise with similar electric pump, can effectively extend the working life of electric pump.
At this, for the consideration of environmental protection sanitary, the impeller 12 in pump 1 part, stator 13 and liquid jetting device 14 are all adopted made of plastic, and not only cost economy, the more important thing is the generation of having stopped corrosion phenomena, avoids carrying liquid contaminated, guarantee to carry the Security of liquid.
In addition, the runner 121 of impeller that the utility model is joined 12 than large 2 mm of existing electric pump, makes the flow of electric pump up to 3-3.5m than wide 1 mm of existing electric pump, liquid jetting device 14 internal diameters
3/ h, has realized the obvious lifting of electric pump flow.
To sum up, the utility model is designed to a kind of jet-type self-absorption electric pump, and it has perfect heat-dissipating, carries liquid safety non-pollution, the feature that flow is large.
The above, it is only better embodiment of the present utility model, not the utility model is done to any pro forma restriction, every foundation know-why of the present utility model, to any simple modification made for any of the above embodiments, equivalent variations or modification, still belongs in the scope of technical solutions of the utility model.
