Description
Technical field
the utility model relates to a kind of axial flow magneto water pump.
Background technique
the axial flow pump providing in conventional art, arranges the pump housing inner chamber of water inlet and outlet in its pump housing shell, impeller is disposed in pump housing inner chamber, and magneto is mounted to the outside of pump housing shell and assembles by coupling shaft and impeller.Because magneto and pump housing inner chamber are separated from each other, therefore the volume of this class axial flow pump is often larger, loosely organized.Because needs configure fan, magneto is carried out cooling on the other hand, therefore component are more, cost of production is higher.
because magneto is easy to realize frequency conversion, be mounted to and on water pump, there is higher efficiency.If but magneto adopts the framework of conventional asynchronous squirrel-cage motor to be combined with water pump, cost is high, volume is large, and radiating efficiency is low.For example, as advantage, magneto external diameter can be done to mate according to the impeller diameter of water pump, yet larger external diameter not only brings the increase of sheathing material cost, and motor windward side is strengthened, be unfavorable for adopting conventional fan form to carry out cooling, have noise problem simultaneously.
if carry out framework axial flow pump therefore adopt at present magneto to substitute conventional asynchronous squirrel-cage motor as driver part, it still exists cost high, and structure tradition, do not make the shortcoming of any optimization, what really do not obtain rationalizing is configured to meet volume, cost, heat radiation, the demand of noise reduction aspect.
Summary of the invention
the utility model object is: provide that a kind of overall structure is more compact, radiating effect is better, the axial flow magneto water pump that cost of production is low simultaneously, noise is little, in order to solve magneto, be incorporated into the technical bottleneck on axial flow pump, really take into account volume, cost, heat radiation, the demand of noise reduction aspect.

in actual embodiment, the quantity of the magneto quantity in the utility model and the impeller being driven by this magneto is also not only limited as one, can be more than one.
and in the scheme of optimizing, when the quantity of magneto is more than one, also comprise the controller that connects and control each magneto independent operating, according to actual flow and lift demand, by controller, optionally send command operating (or closing) a few or whole magneto runnings wherein, thereby reach energy-conservation object.
and in scheme more concrete and that optimize, angle or the external diameter of the corresponding impeller of different magnetoes in the utility model, or angle is all different with external diameter.Its running usefulness of different angles or the impeller of external diameter is different, therefore according to actual flow and lift demand, optionally send the wherein magneto running of particular impeller of command operating (or closing), thereby reach energy-conservation object by controller.
in actual embodiment, magneto described in the utility model comprises that (the configuration structure form for rotor is not construed as limiting for stator and rotor, it can be inner stator external rotor configuration, also can be internal rotor external stator configuration), described rotor is arranged in pump housing inner chamber, and by water-insulating cover, separates between rotor and stator.
and in further scheme, described impeller can directly fix or Integral design on rotor.
or, in described pump housing shell, being fixed with the axle that runs through magneto center, described impeller set is located on described axle.
or, in described pump housing shell, being provided with the rotatable axle that runs through magneto center, described axle and rotor are fixed, and described impeller is fixed on described axle.
or, in described pump housing shell, being provided with the rotatable axle that runs through magneto center, described rotor is fixed by impeller and axle.
it is to be noted: in the utility model, only the design of pump housing inner chamber is passed through from the center of magneto, be not confined to magneto inside, when therefore reality is implemented, the impeller being disposed in pump housing inner chamber is not confined in magneto yet, only need guarantee that current pass through from magneto center.
the utility model has the advantages that:
1. the improvement that the utility model is compared routine techniques maximum be to make pump housing inner chamber from the center of magneto by (be also in pump current from the center of magneto by), magneto and pump housing inner chamber are organically integrated, this improvement simplifies the structure on the one hand, make pump overall volume less, reduce pump housing sheathing material simultaneously, saved cost of production; On the other hand, because current directly flow through from magneto center, can directly by water-cooled, to stator, implement heat radiation, thereby save conventional fan component, further reduce cost of production, and abated the noise.
therefore the utility model has solved magneto and has been incorporated into the technical bottleneck on axial flow pump, has really accomplished to take into account volume, cost, heat radiation, the demand of noise reduction four aspects.
water pump of the present utility model is in work engineering, and its constituent directly adopts the pump housing inner chamber as work water channel, and arranges without the extra water channel of configuration, simplifies the structure, and has reduced cost of production; And because of water pump in the course of the work the current in pump housing inner chamber constantly flow and take away stator heat, therefore can obtain extraordinary radiating effect.
