Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.
Like Fig. 1-shown in Figure 3, this integral type permanent magnetism recycle pump comprises the pump housing, motor and electric machine controller, and its middle pump body comprises pump case 1, impeller 2, and motor comprises stator 4, rotor 5, motor housing 3 and end cap 31.
Specifically, pump case 1 is arranged on motor housing 3 front ends, is connected with motor housing 3 through screw, and impeller 2 is set in the pump case 1, and impeller 2 is fixedly mounted on an end of rotor shaft 51; Motor also comprises housing 7, and housing 7 is solidly fixed with motor housing 3 and constitutes one can be with the cavity 71 of stator 4 sealings in it, and near an end of end cap 31 fairlead 32 is set at cavity 71.Motor is electrically connected with electric machine controller, is that stator 4 is connected with electric machine controller specifically, and stator 4 is arranged in the cavity 71, and its lead-in wire passes fairlead 32 and is electrically connected with electric machine controller.Rotor shaft 51 two ends of rotor 5 are connected with housing 7 through stop collar 52 and stuffing box gland 53 respectively; Wherein an end stretches out stop collar 52 and housing 7 and is connected with impeller 2; The other end and stuffing box gland 53 active links are positioned at rotor shaft 51 on the axostylus axostyle of housing 7 and are fixed with the p-m rotor of being processed by permanent magnet 5, these p-m rotor 5 unsettled being arranged in the housing 7; Can in the magnetic field that stator 4 produces, rotate, but axial restraint.On stop collar 52, offer some apertures, preferably four of its quantity.
In this enforcement row, cavity 71 mainly is that the two ends and the outside by the two ends of motor housing 3 and inwall and housing 7 forms, and wherein the two ends of motor housing 3 are solidly fixed with housing 7 two ends mutually, and motor housing 3 and housing 7 are plastic materials and process.In the actual manufacture process, stator 4 is fixed in the mould of motor housing 3 and housing 7, through the injection moulding straight forming, motor housing 3 is connected with housing 7 naturally, need not to assemble once more.
This integral type permanent magnetism recycle pump in the course of the work; Medium is 8 entering pump cases 1 from the medium inlet; Get in the housing 7 through the aperture on the stop collar 52 again, the p-m rotor 5 of quick rotation is played cooling and lubrication, because housing 7 the other ends seal with stuffing box gland 53; Medium can be discharged in the pump case 1 in housing 7 through aperture once more, goes out from media outlet 9 again.Because housing 7 is fixed with one with motor housing 3, so medium can't get into the cavity 71 at stator 4 places, stator 4 can not receive erosion, the damage of medium, makes the life-span of recycle pump obtain increasing.The motor housing 3 of this integral type permanent magnetism recycle pump, housing 7, end cap 31 and Direct box 6 all adopt plastic materials to process; Make that the whole weight of the pump housing is lighter, and can need not to assemble once more through molding and forming; Make things convenient for the manufacturing of water pump, saved manufacture cost simultaneously.
