Description
Technical field
The utility model relates to a kind of vertical or horizontal multi-stage water pump.
Background technique
Pump is the visual plant of fed sheet of a media, is the main tool of plumbing.At present, the stator in water pump all adopts with on impeller coaxial package and pump shaft, and it not only brings very large pressure to pump shaft, reduces the power of pump shaft, simultaneously again because stator does not rotate with pump shaft, also needs to add the parts such as bearing, cost is high, assembling trouble.
Summary of the invention
The purpose of this utility model is the defect existed for prior art, provides a kind of easy to assembly, water pump that cost is low.
For achieving the above object, the utility model adopts following technical proposals: a kind of water pump, primarily of water pump cover, pump motor, the pump shaft driven through coupling by pump motor, and be arranged on the compositions such as impeller on pump shaft, described water pump cover is provided with the exhalant canal be connected with water outlet, enclose and be positioned at impeller outer and the stator being communicated in exhalant canal, exhalant canal and stator are shaped on water pump cover, space is left between described stator and impeller, diversion cavity is formed between the annular inner wall of stator and outer wall, some equally distributed arc guide vanes are provided with between the inwall of stator and outer wall, between stator inwall and outer wall, turbotype structure fluid passage is formed by arc guide vane.
Improve as one: described impeller is multi-stage impeller, described stator is multistage stator, and multi-stage impeller is identical with the progression of multistage stator, is coupled to each other between multistage stator, final stage stator in multistage stator is communicated with exhalant canal, and stator at different levels encloses this grade of impeller outer being positioned at and matching.
Improve as one: the progression of described multi-stage impeller and multistage stator is two-stage.
Improve as one: the stator that described enclosing is positioned at impeller outer is arranged with impeller is concentric.
Improve as one: described water pump cover is by bottom, pump cover frame and be located in active section shell between bottom, pump cover frame and mutually assembly, described impeller is installed in active section shell, and described exhalant canal, stator are all shaped in active section shell.
Adopt the water pump of such scheme, because its stator is shaped on water pump cover, support without the need to other component and fix, decreasing the expense of expensive bearing member, greatly reduce costs, and structure is simple, assembling more simplifies.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Embodiment
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of embodiment of the utility model water pump, primarily of water pump cover 1, pump motor 2, the pump shaft 3 driven through coupling 6 by pump motor 2, and be arranged on the compositions such as impeller 4 on pump shaft 3, described water pump cover 1 is provided with the exhalant canal 1a be connected with water outlet, enclose that to be positioned at impeller 4 outer and be communicated in the stator of exhalant canal 1a, exhalant canal 1a and stator 5 are shaped on water pump cover 1, space is left between described stator 5 and impeller 4, diversion cavity is formed between the annular inner wall of stator 5 and outer wall, some equally distributed arc guide vane 5a are provided with between the inwall of stator 5 and outer wall, between stator inwall and outer wall, turbotype structure fluid passage is formed by arc guide vane 5a, stator makes fluid enter exhalant canal 1a in order, the fluid of good reduction after impeller 4 supercharging is to the unnecessary collision friction of pump body, reduce noise.Enclose the stator 5 be positioned at outside impeller 4 to arrange with impeller 4 is concentric, improve water rate and stability.The water pump cover 1 of the present embodiment is by bottom 1.1, pump cover frame 1.2 and be located in active section shell 1.3 between bottom 1.1, pump cover frame 1.2 and mutually assembly, described impeller 4 is installed in active section shell 1.3, described exhalant canal 1a, stator 5 are all shaped in active section shell 1.3, with convenient for assembly.
In order to improve lift, above-mentioned impeller 4 can be multi-stage impeller, and stator 5 can be multistage stator, multi-stage impeller is identical with the progression of multistage stator, be coupled to each other between multistage stator, the final stage stator in multistage stator is communicated with exhalant canal 1a, and stator 5 at different levels encloses outside this grade of impeller 4 that be positioned at and match.The present embodiment is two-stage water pump, and the impeller 4 namely adopted is both stage impellers, and stator 5 is the two-stage stator 5 identical with the progression of both stage impellers.The centrifugal of two-stage water pump is stablized, and just can reach higher lift at the slightly large impeller 4 of use after two-step supercharging.Namely at the certain lift of guarantee simultaneously, volume is little, especially environment that is as low in high building basement equal altitudes, limited space is applicable to, moreover the diameter of both stage impellers reduces successively with the flow direction of fluid along pump shaft, reduce impeller torque step by step, avoid the appearance of liquid vacuum section, thus avoid the appearance of cavitation phenomenons, make the Security of product, low noise, high-lift, life-span be able to fine guarantee.
