Description

Opposite-rotary axial flow type submersible sewage pump
Technical field
A kind of submersible sewage pump is the utility model is related to, more particularly to a kind of axial-flow type submersible sewage pump.
Background technology
The application of axial-flow type submersible sewage pump is very extensive.The working method of existing axial-flow type submersible sewage pump is mostly that impeller is directly installed in On the axle of motor, static stator is then equipped with again, the part kinetic energy of liquid is converted into by liquid pressure energy by stator.Shortcoming It is that lift is low, axial dimension and weight are larger, and runing adjustment poor performance, range of flow is small, narrow application range, need to improve.
The content of the invention
The purpose of this utility model is to provide a kind of follow-on axial-flow type submersible sewage pump so that the axial-flow pump has flow Greatly, the advantages of lift height, small volume, the liquid that conveying winds material containing larger particles and easily is advantageous to.
The utility model uses opposite-rotary axial flow type impeller, is both stage impellers, is driven respectively by two motors, while reversely rotation Turn, transfer energy to the liquid pumped jointly, the energy increase of liquid, have flow big, lift is high, small volume it is excellent Point.Blade is specially treated, is advantageous to the liquid that conveying winds material containing larger particles and easily.
Concrete technical scheme is as follows:
Opposite-rotary axial flow type submersible sewage pump, including the pump housing, the one stage impeller of pump body is arranged on, with one stage impeller drive connection One-level motor, in addition to the sencond stage impeller for being arranged in the pump housing, being oppositely arranged with one stage impeller, the sencond stage impeller and two level Motor drive connection.
Further, the one stage impeller is arranged along liquid flow path direction, and the sencond stage impeller is along the reverse cloth of liquid flow path direction Put.
Further, one-level radome fairing is additionally provided with the outside of the one-level motor, two level is set on the outside of the two level motor Radome fairing.
The utility model uses opposite-rotary axial flow type impeller, is both stage impellers, is driven respectively by two motors, while reversely rotation Turn, the advantages of two impellers do work to liquid jointly, not only big with flow, and lift is high, small volume, axial-flow type submersible sewage pump can be improved Efficiency, reduce manufacturing cost;Also the runing adjustment performance of pump can be strengthened, expand its high efficient district scope.Blade is specially treated, has The liquid of material is wound containing larger particles and easily beneficial to conveying.
Brief description of the drawings
Fig. 1 is utility model structural representation;
Wherein:1st, the pump housing, 2, one stage impeller, 3, sencond stage impeller, 4, two level radome fairing, 5, two level motor, 6, one-level motor, 7th, one-level radome fairing.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the present invention will be further described.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining this Utility model, it is not used to limit the utility model.
Such as Fig. 1 and shown, the utility model discloses a kind of opposite-rotary axial flow type submersible sewage pump, including the pump housing 1, the pump housing is arranged on One stage impeller 2 inside 1, the one-level motor 6 with the drive connection of one stage impeller 2, in addition to be arranged in the pump housing 1, with one-level leaf The sencond stage impeller 3 that wheel 2 is oppositely arranged, the sencond stage impeller 3 and the drive connection of two level motor 5.
In the present embodiment, the one stage impeller 2 is arranged along liquid flow path direction, and the sencond stage impeller 3 is anti-along liquid flow path direction To arrangement.It that is to say, one stage impeller 2 is arranged in the water inlet of the pump housing 1, can be evacuated to out liquid stream from water inlet after wheel rotation At the mouth of a river;Similarly, sencond stage impeller 3 then provides an active force with the opposite direction of one stage impeller 2 so that liquid stream can be in one stage impeller Compressed in axial gap between 2 and sencond stage impeller 3.
In the present embodiment, axial gap is left between the one stage impeller 2 and the sencond stage impeller 3.
In the present embodiment, the outside of one-level motor 6 is additionally provided with one-level radome fairing 7, and the outside of two level motor 5 is set Two level radome fairing 4.
The convection rotary type impeller that the utility model uses, two impellers are all rotations, and the effect of rear stage impeller is not only by liquid The kinetic energy of body is converted into pressure energy, moreover it is possible to liquid is done work, the mechanical energy of its main shaft is converted into liquid energy, therefore two impellers are total to With the liquid pumped is transferred energy to, the energy of liquid increases.
After being improved by said structure, this submersible sewage pump not only has the advantages of flow is big, more causes the lift of pump to improve, has The liquid of material is wound containing larger particles and easily beneficial to conveying.
Above-described embodiment is this preferred embodiment, is not the limitation to technical solution of the present invention, as long as without The technical scheme that creative work can be realized on the basis of above-described embodiment is crossed, is regarded as falling into the power of patent of the present invention In sharp protection domain.
