Description
Technical field
The present invention relates to sewage pump technical field, is related specifically to a kind of high-lift sewage electric pump of multi-stage impeller.
Background technology
Sewage electric pump belongs to one kind of centrifugal impurities pump, with various ways：Such as two kinds of submersible type and dry type, most normal at present
Submersible type is QW type submerged sewage pumps, modal dry type the sewage pump such as horizontal sewage pump of W types and WL type vertical sump pumps
Two kinds.Mainly for delivery of municipal sewage, in feces or liquid fiber is contained.
The overwhelming majority is provided with single impeller in the sewage electric pump of prior art, so that the lift of sewage electric pump is relatively low, it is difficult
So that sewage transport to be processed to the higher position of lift demand, the sewage electric pump of this kind of structure has had a strong impact on sewage electric pump
Practical Performance, to sewage electric pump blowdown work bring greater inconvenience.
But for the deficiencies in the prior art, developer be necessary to develop a kind of reasonable in design, simple structure, can be by dirt
Water is transported to the higher position of lift demand and carries out processing and the high-lift sewage electric pump of the strong multi-stage impeller of Practical Performance.
The content of the invention
To solve the problems, such as prior art, the object of the invention provide a kind of reasonable in design, simple structure, can be by
Sewage transport carries out processing and the high-lift sewage electric pump of the strong multi-stage impeller of Practical Performance to the higher position of lift demand.
To solve above technical problem, the present invention employs the following technical solutions to realize：
A kind of high-lift sewage electric pump of multi-stage impeller, including motor and the pump housing of motor lower end is arranged on,
The lower end of the pump housing is provided with base, and the output shaft of the motor is connected with the rotary shaft of the pump housing, on the base
Water inlet is provided with, on the pump housing outlet is provided with, it is characterised in that in the rotary shaft of the pump housing along its length
It is interval with least two impellers.
In a preferred embodiment of the invention, the sliding bearing for preventing rotating shaft distortion is provided with the base.
Compared with prior art, the present invention is interval with along its length at least two leaves in the rotary shaft of the pump housing
Wheel, adopting the structure can be processed sewage transport to the higher position of lift demand, effectively raise the sewage
The Practical Performance of electric pump；Another, is provided with sliding bearing on base, and the lower end of rotary shaft is arranged on sliding bearing, can
Effectively prevent from rotating shaft distortion, further increase the service life of the sewage electric pump.
Description of the drawings
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this

Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
With reference to shown in Fig. 1, the high-lift sewage electric pump of a kind of multi-stage impeller be given in figure, including motor 100 and set
The pump housing 200 in the lower end of motor 100 is put, the pump housing 200 is fixedly mounted on the lower end of motor 100 by bolt 400.
Base 300 is provided with the lower end of the pump housing 200, base 300 is fixedly mounted on the lower end of the pump housing 200 by bolt 500
On, the output shaft 110 of motor 100 is connected with the rotary shaft 210 of the pump housing 200, and water inlet 310 is provided with base 300,
Outlet 220 is provided with the pump housing 200, outlet 220 is connected with the water pipe of conveying sewage.
It is interval with least two impellers 211, this kind of structure energy along its length in the rotary shaft 210 of the pump housing 200
Enough lifts for effectively improving sewage electric pump, can be processed sewage transport to the higher position of lift demand, effectively
The Practical Performance of the sewage electric pump is improve, in the present embodiment the quantity of impeller is 4.
The sliding bearing 320 for preventing rotary shaft 210 from deforming is provided with base 300, the lower end of rotary shaft 210 is arranged on cunning
On dynamic bearing 320, can effectively prevent rotary shaft 210 from deforming, further increase the service life of the sewage electric pump.
In sum the present invention is interval with along its length at least two impellers in the rotary shaft of the pump housing, adopts this
Planting structure can be processed sewage transport to the higher position of lift demand, effectively raise the practicality of the sewage electric pump
Performance；Another, is provided with sliding bearing on base, and the lower end of rotary shaft is arranged on sliding bearing, can effectively prevent
Rotation shaft distortion, further increases the service life of the sewage electric pump.
Ultimate principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not restricted to the described embodiments, the simply explanation described in above-described embodiment and description this
The principle of invention, of the invention without departing from the spirit and scope of the present invention also to have various changes and modifications, these changes
Change and improvement is both fallen within scope of the claimed invention.The claimed scope of the invention by appending claims and its
Equivalent is defined.
