Description

A kind of centrifugal pump
Technical field
The present invention relates to a kind of pump, particularly the multistage centrifugal pump of the many motors of a kind of tandem.
Background technique
In prior art, carry for realizing the long distance of liquid, often select high-power centrifugal pump to realize, but this centrifugal pump often price is high, and working life not fully up to expectations.Therefore, small-power centrifugal pump is connected to increase liquid transporting apart from can yet be regarded as a kind of effective method, still, how small-power centrifugal pump reasonable combination being still to one has problem to be solved.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide the multistage centrifugal pump of the many motors of a kind of tandem, not only can realize higher lift, and with the multistage centrifugal pump comparison of a single motor, cost is lower, and also greatly increase working life.
For addressing the above problem, the technical solution adopted in the present invention is as follows:
A kind of centrifugal pump, is made up of housing, impeller and DC brushless motor, is provided with motor slot and pump head in described housing, and described pump head is provided with feed-water end and waterexit end; Described motor comprises the first motor and the second motor, described impeller comprises the first impeller and the second impeller, described the first motor, the second motor are set up in parallel respectively in housing the first motor slot, the second motor slot, described the first impeller, the second impeller respectively correspondence are arranged in housing the first pump head, the second pump head and with the first motor, the second motor and match and form pump I and pump II, and described the first pump head waterexit end is communicated with the second pump head feed-water end.
Described the first impeller, the second impeller are enclosed or unshrouded impeller.
Described the first pump head feed-water end shaft axis is vertical with the second pump head waterexit end shaft axis.
Described the first pump head waterexit end shaft axis is vertical with the second pump head feed-water end shaft axis.
Compared to existing technology, beneficial effect of the present invention is:
1, in the present invention, centrifugal pump has higher lift, carries liquid a kind of alternative approach is provided for long distance;
2, cost of the present invention reduces greatly with respect to high-power centrifugal pump, is suitable for the application of high-lift straightway pump;
3, the present invention is optimized the each structure of centrifugal pump: the weight of single rotor is little, and its dynamic balancing is better, and noise is low, and the life-span is long, avoids the generation of air sinuses phenomenon in centrifugal pump, improves the utilization efficiency of machine.
Brief description of the drawings
Fig. 1 is centrifugal pump overall structure schematic diagram in the present invention;
Fig. 2 is centrifugal pump cross-sectional view in the present invention;
Wherein, 1 is housing, and 2 is pump I, and 201 is the first motor, and 202 is the first impeller, and 3 is pump II, and 301 is the second motor, and 302 is the second impeller, and 4 is the first pump head feed-water end, and 5 is the second pump head waterexit end.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As illustrated in fig. 1 and 2, be centrifugal pump of the present invention, formed by housing 1, impeller and motor, in described housing, be provided with motor slot and pump head, described pump head is provided with feed-water end and waterexit end; Described motor comprises the first motor 201 and the second motor 301, described impeller comprises the first impeller 202 and the second impeller 302, described the first motor 201, the second motor 301 are set up in parallel respectively in housing 1 first and second motor slot, described the first impeller 202, the second impeller 302 are separately positioned in housing 1 first and second pump head and with the first motor 201, the second motor 201 and match and form pump I 2 and pump II 3, and described the first pump head waterexit end is communicated with the second pump head feed-water end.In preferred version, described the first motor 201 and the second motor 301 are DC brushless motor; Described the first impeller 202, the second impeller 302 are selected enclosed or unshrouded impeller; Described the first pump head feed-water end 4 shaft axiss are vertical with the second pump head waterexit end 5 shaft axiss; Described the first pump head waterexit end shaft axis is vertical with the second pump head feed-water end shaft axis; Described the first pump head waterexit end shaft axis is vertical with the second pump head feed-water end shaft axis, and described the first volute chamber feed-water end 4 diameters are not less than the first volute chamber waterexit end diameter; Described the first volute chamber waterexit end diameter is not less than the second volute chamber feed-water end diameter; The flow of described pump I 2 is not less than the flow of pump II 3, and the lift of pump I 2 is not more than the lift of pump II 3, has ensured that like this pump II 3 can not produce air sinuses phenomenon, makes efficiency of centrifugal pump higher.
When centrifugal pump of the present invention uses, liquid enters centrifugal pump from the first pump head feed-water end 4, under the effect of pump I 2 first impellers 202, enters the second pump head feed-water end through the first pump head waterexit end, under the effect of pump II 3 second impellers 302, discharge by the second pump head waterexit end 5.
In the present invention, centrifugal pump has higher lift, can realize the long distance of liquid and carry, and carries liquid a kind of alternative approach is provided for long distance; And cost reduces greatly with respect to high-power centrifugal pump, increase working life, is suitable for spread and uses.
To one skilled in the art, can be according to technological scheme described above and design, make other various corresponding changes and deformation, and within these all changes and deformation all should belong to the protection domain of the claims in the present invention.
