Background technique
The backwater structure of the water circulation cooling motor of general submerged sewage pump, is typically designed to following two kinds of structures:
Structure one: external pipeline circulation cooling mechanism
Fig. 1 is external pipeline cooling structure schematic diagram.As shown in Figure 1: external pipeline type cooling structure, open water passage hole on spiral case diffusing tube surface and motor component cooling cylindrical shell, need external pipeline 1 can realize the effect of circulation cooling electromechanical between the two.This structure have impact on the hydraulic performance of pump in the perforate of diffusing tube key position, external pipeline complicated structure, and cooling effect is not good.
Structure two: ordinary cycle cooling structure
Fig. 2 is ordinary cycle cooling structure schematic diagram.Fig. 3 is backwater structure part (A place) enlarged diagram in Fig. 2.As shown in Figures 2 and 3: mark in figure 2 is pump cover and impeller deutostoma czermak space, mark 3 be pump housing water passage hole, mark 4 be pump cover water passage hole, mark 5 be connecting base water passage hole, mark be 6 motor casing water passage holes, the pump end of common inner circulation type cooling structure need at pump housing end face of flange design water passage hole, when circulating cooling, water need turn 90 degree and enter pump housing end face of flange backwater hole through impeller port ring gap, then could arrive motor cavity through connecting base backwater hole.The backwater hole of connecting base is two closed through holes, and in the process of backwater, distance is oversize.
This backwater structure, complex structure, difficulty of processing is large, and matching requirements are higher, and easily cause water pump assembly operationally water return loop blocking phenomenon, cooling effect is not good, during water pump long-time running, motor easily generates heat, and affects the normal operation of water pump, shortens the working life of water pump.
Model utility content
For the problems referred to above, main purpose of the present utility model is to provide a kind of motor side of submersible motor to design a set of water circulation cooling jacket cylinder, at the backwater structure of the submerged sewage pump water circulation cooling motor of uniform two through holes of the drum surface of outer sleeve.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of backwater structure of submerged sewage pump water circulation cooling motor, the motor side that described backwater structure is included in submersible motor designs a set of water circulation cooling jacket cylinder, at uniform two through holes of the drum surface of outer sleeve, cylindrical shell uses two cylinder circles and barrel soldering up and down, cylindrical shell is directly inserted in motor casing from top to down, cylinder circle above and motor casing are Spielpassung, and cylinder circle is below fixedly connected with between pump cover; The cavity that the water passage hole and the outer sleeve that design two backwater in pump end pump cover chamber are formed forms a unimpeded loop, while leave gap at pump cover and impeller deutostoma interannular.
In specific embodiment of the present utility model, cylinder circle is below connected with pump cover bolt.
Positive progressive effect of the present utility model is: the backwater structure of the submerged sewage pump water circulation cooling motor that the utility model provides has the following advantages: the utility model designs a set of water circulation cooling jacket cylinder in the motor side of submersible motor, at uniform two through holes of the drum surface of outer sleeve, reduce the noise produced when submersible pump runs, improve submersible pump reliability of operation, the backwater structure of circulation cooling electromechanical extends the working life of submersible pump, cost-saving.

Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
Fig. 4 is overall structure schematic diagram of the present utility model.Fig. 5 is cooling jacket cylinder cylindrical shell water passage hole enlarged diagram (the B place enlarged view of Fig. 4).Fig. 6 is related components water passage hole enlarged diagram (the C place enlarged view of Fig. 4).In figure 6, be labeled as 11 for pump cover water passage hole, be labeled as 12 be lower end cap water passage hole, be labeled as 13 be motor casing water passage hole, be labeled as 14 be outer sleeve Inner eycle chamber, wherein pump cover is connected with outer sleeve bolt 15.Fig. 7 is pump cover and impeller deutostoma czermak space enlarged diagram (the D place enlarged view of Fig. 4).As shown in figs. 4-7, the motor side that the utility model is included in submersible motor designs a set of water circulation cooling jacket cylinder, at uniform two through holes in cylindrical shell 16 surface of outer sleeve, cylindrical shell about 16 two cylinder circles and barrel soldering, cylindrical shell is directly inserted in motor casing from top to down, cylinder circle above and motor casing are Spielpassung, and cylinder circle is below fixedly connected with between pump cover; The cavity that the water passage hole 7 designing two backwater in pump end pump cover chamber and outer sleeve are formed forms a unimpeded loop, while after pump cover 8 and impeller, leave gap 10 between choma 9.Cylinder circle below and pump cover are general also with bolts.
The backwater structure of new type water circulation cooling electromechanical, without the need to external pipeline, only need design a set of water circulation cooling jacket cylinder in the motor side of submersible motor, at uniform two through holes of the drum surface of outer sleeve, cylindrical shell welds with it with two cylinder circles up and down, directly be inserted in motor casing from top to down, upper canister ring and motor casing are Spielpassung, and lower canister ring is connected with pump cover bolt; The cavity that the water passage hole and the outer sleeve that design two backwater in pump end pump cover chamber are formed forms a unimpeded loop, while leave certain gap at pump cover and impeller deutostoma interannular.The backwater structure of this water circulation cooling motor, structure is simple, easily processes, and easy to assembly.The cooling jacket cylinder of motor component makes whole motor be tubular, and resistance is damaged little, and more coordinates with the pump head parts of water pump, beautiful shape.
When pump assembly fills water in normal operation, pump chamber, by the gap after pump cover 8 and impeller between choma 9, aqueous medium is sent into continuously the circulation loop of pump cover and outer sleeve, continually carry out energy interchange with the external world, the heat that when taking away pump operation, motor produces, reach the effect of circulation cooling electromechanical, be conducive to submerged sewage pump when dry type installation environment or water level very low also can normally run, effectively can reduce the noise produced when pump assembly runs simultaneously, improve the reliability of water pump operation, extend the working life of water pump, cost-saving.
