Abstract
A kind of small volume submersible pump, comprise shell, motor room and the pump housing, it is characterized in that: seal completely between described motor room and the pump housing, this motor output shaft one end is provided with set of permanent magnets A; The described pump housing is that namely cylindrical chamber structure forms water-inlet cavity, described pump housing outer wall forms spiral groove, is provided with pump shaft in the described pump housing, and this axle one end is provided with set of permanent magnets B, and described pump shaft is provided with impeller.The small volume submersible pump that the utility model provides, be applicable to the pump water operation under some particular surroundingss, hole as less in some or finedraw, all by, the spiral groove design of its pump housing while reduction pump volume, can ensure efficiency during submersible pump work.
Description
Technical field
The utility model relates to a kind of submersible pump, is specifically related to a kind of small volume submersible pump.
Background technique
Submersible pump can pump liquid from the space in container, vertical shaft, building etc., is widely used in domestic water, speedily carry out rescue work in mine, industry cools, field irrigation, seawater lift, steamer adjust and carry.In order to deep liquid being pumped, the power of submersible pump is general all larger, and this also causes the volume of submersible pump mostly larger, and under the environment that some are special, such as less hole, the submersible pump of large volume cannot enter normal work.
And small-sized submersible pump, although volume can meet some special working environments, due to the power limited of micro-machine, the power of submersible pump can be limited like this, affect its working effect.
Model utility content
In order to solve the problem of above-mentioned prior art, the utility model proposes a kind of small volume submersible pump, concrete technological scheme is as follows:
A kind of small volume submersible pump, comprise shell, motor room and the pump housing, seal completely between described motor room and the pump housing, this motor output shaft one end is provided with set of permanent magnets A; The described pump housing is that namely cylindrical chamber structure forms water-inlet cavity, described pump housing outer wall forms spiral groove, is provided with pump shaft in the described pump housing, and this axle one end is provided with set of permanent magnets B, and described pump shaft is provided with impeller.
Further, the impeller on described pump shaft is two groups, and the spacing of these two groups of impellers equals pump housing length, improves its effect when the operation of pump water.
Further, described pump housing lower end offers water intake, and described pump housing upper end offers water outlet.
Further, the magnetic pole of described set of permanent magnets A and the pole pair of set of permanent magnets B should.
The beneficial effects of the utility model are:
A kind of small volume submersible pump that the utility model provides, is applicable to the pump water operation under some particular surroundingss, hole as less in some or finedraw, all by.The pump housing wall of this submersible pump forms spiral groove, and is provided with two groups of impellers at the upper and lower end of pump shaft, while reduction pump volume, efficiency during submersible pump work can be ensured.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Figure number and title: 1, shell, 2, set of permanent magnets A, 3, water outlet, 4, the pump housing, 5, pump shaft, 6, water intake, 7, set of permanent magnets B, 8, motor room, 9, motor.
Embodiment
Now by reference to the accompanying drawings the utility model is further illustrated:
A kind of small volume submersible pump as shown in Figure 1, comprises shell 1, motor room 8 and the pump housing 4, seals completely between described motor room 8 and the pump housing 4, and this motor 9 output shaft one end is provided with set of permanent magnets A; The described pump housing 4 is cylindrical chamber structure, namely forms water-inlet cavity, described pump, 4 outer walls form spiral groove, is provided with pump shaft 5 in the described pump housing 4, and this pump shaft 5 one end is provided with set of permanent magnets B, and described pump shaft 5 is provided with impeller.
Impeller on described pump shaft 5 is two groups, and the spacing of these two groups of impellers equals the pump housing 4 length, and the object arranging two groups of impellers is the effect of pump water when improving the work of this submersible pump.
The magnetic pole of described set of permanent magnets A and the pole pair of set of permanent magnets B should.
The described pump housing 4 lower end offers water intake 6, and the described pump housing 4 upper end offers water outlet 3.
Working principle of the present utility model is:
During use, submersible pump is inserted in liquid, the output shaft of motor drives set of permanent magnets A to rotate, because the magnetic pole of set of permanent magnets B is corresponding with set of permanent magnets A, set of permanent magnets B starts to rotate under the magnetic force of set of permanent magnets A, drives pump shaft to rotate, impeller on pump shaft starts to rotate, liquid enters in the pump housing by water intake, through being with the water-inlet cavity of spiral grooves, discharges finally by water outlet.
The above is preferred embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in patent claim of the present utility model.
