Description
Technical field
the present invention 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 by coupling shaft and impeller assembling.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.Magneto is carried out cooling because needs configure fan 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, but 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 present invention seeks to: 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, be incorporated into the technical bottleneck on axial flow pump in order to solve magneto, really take into account volume, cost, heat radiation, the demand of noise reduction aspect.
technological scheme of the present invention is: a kind of axial flow magneto water pump, comprise pump housing shell, for configuring the pump housing inner chamber of impeller and the magneto for drives impeller rotation, and on pump housing shell, have the entery and delivery port being connected with pump housing inner chamber; It is characterized in that described magneto is located in pump housing shell, pump housing inner chamber passes through from the center of magneto.
in actual embodiment, the quantity of the magneto quantity in the present invention and the impeller that driven by this magneto is also not only limited as one, can be more than one.
and in the scheme of optimizing, in the time that 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, optionally send command operating (or closing) a few or whole magneto runnings wherein by controller, 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 present invention, or angle is all different with external diameter.Its running usefulness difference of different angles or the impeller of external diameter, therefore according to actual flow and lift demand, optionally send the wherein magneto running of particular impeller of command operating (or closing) by controller, thereby reach energy-conservation object.
in actual embodiment, magneto described in the present invention 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 separates by water-insulating cover 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 present invention, only the design of pump housing inner chamber is passed through from the center of magneto, be not confined to magneto inside, therefore when 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.
advantage of the present invention is:
1. the improvement that the present invention compares routine techniques maximum be to make pump housing inner chamber from the center of magneto by (being also that in pump, current pass through from the center of magneto), 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 implement heat radiation by water-cooled to stator, thereby save conventional fan component, further reduce cost of production, and abated the noise.
therefore the invention solves magneto and be incorporated into the technical bottleneck on axial flow pump, really accomplished to take into account volume, cost, heat radiation, the demand of noise reduction four aspects.
water pump of the present invention 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.
