Description
Technical field
The utility model relates to a kind of water pump, relates in particular to a kind of compact heat radiating type motor water pump.
Background technique
Due to existing water pump, stator and driving circuit board separate two-part, are not assembled together, and cause machine volume very much not easy to use.
Existing water pump on the market needs high speed rotating, works long hours in addition, the problem that it is difficult that ubiquity dispels the heat, and heat radiation will cause the working life that is more prone to mechanical failure, shortens water pump not in time.And general water pump only has single mode of operation, can not deal with different operative scenario demands, thereby cause power consumption higher.
Model utility content
The technical problem that the utility model water pump will solve is, provides that a kind of volume is less, the water pump of compact structure.Another problem to be solved in the utility model is to provide the motor water pump that is easy to heat radiation, multi-operation mode.
The utility model solves the technological scheme that its technical problem adopts: a kind of water pump, comprise middle seat, stator, rotor, metal cylinder, driving circuit board, metal-oxide-semiconductor, bearing, bearing bracket, circuit board support, described metal cylinder is fixed in described middle seat, and described stator is arranged at metal cylinder periphery; Described rotor is installed on metal cylinder inside center by bearing and bearing bracket; It is inner that described driving circuit board is fixed on middle seat by circuit board support, between described metal-oxide-semiconductor and described metal cylinder, is provided with heat radiation rubber cushion, and the gap-fill between described stator, driving circuit board and middle seat has sealing resin.
Described driving circuit board is connected with power line; Described water pump end is provided with impeller, and described impeller outside is provided with volute.
Described rotor is positioned at described metal cylinder inner side, and described metal cylinder is thin-wall metal cylinder.
Described rotor center is provided with the passage of the water flow running through, and is provided with the passage of water flow between described rotor and described metal cylinder.
Described water pump is any one water pump in permanent rotating speed pattern or permanent torque mode or aforementioned both mixed mode.
The beneficial effect that the utility model reaches is: it is inner that described driving circuit board is fixed on middle seat by circuit board support, and structure is very compact; Between metal-oxide-semiconductor and described metal cylinder, be provided with heat radiation rubber cushion, the heat that the metal-oxide-semiconductor on driving circuit board produces can shed by metal cylinder; Water flows through between metal cylinder and rotor, the heat producing while taking away the work such as stator and driving plate metal-oxide-semiconductor.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model water pump is described in further detail:
Fig. 1 is the metal cylinder, stator of the utility model water pump, the structural representation of middle seat;
Fig. 2 is the cross-sectional view of the utility model water pump;
Fig. 3 is the complete machine structure schematic diagram of the utility model water pump;
Fig. 4 is the schematic diagram of the mobile passage of the utility model water pump internal water.
Embodiment
A kind of water pump as shown in Figure 1,2,3, 4, comprise middle seat 1, stator 2, rotor 3, metal cylinder 4, sealing resin 5, driving circuit board 6, metal-oxide-semiconductor 7, heat radiation rubber cushion 8, bearing 9, bearing bracket 10, circuit board support 11, power line 12, impeller 13 and volute 14.
Metal cylinder 4 is fixedly connected with middle seat 1, and it is fixedly connected with mode is injection moulding encapsulate or screw means of fixation.
Stator 2 is arranged at the position between metal cylinder 4 peripheries and middle seat 1, and fill with sealing resin 5 in the gap between middle seat 1 and stator 2.After solidifying, sealing resin 5 can protect stator to avoid the destruction of water, moisture and dust etc.
Two bearings 9 are fixing with metal cylinder 4 by bearing bracket 10, and bearing 9 plays the supporting effect to rotor 3, and rotor 3 can be rotated smoothly.
Rotor 3 is contained in metal cylinder 4 central interior, and for the ease of electromagnetic induction in work, this rotor 3 also mates in same vertical position mutually with stator 2.
Driving circuit board 6 is contained in aforementioned middle seat 1 inside, is provided with metal-oxide-semiconductor 7 on driving circuit board 6, and this metal-oxide-semiconductor 7 contacts with metal cylinder 4 by heat radiation rubber cushion 8.
Aforementioned driving circuit board 6 connecting power lines 12, after energising, the built-in driver of driving circuit board 6 is controlled stator 2 and is produced rotating magnetic field, and rotation is also followed in rotor 3 these magnetic fields of induction, thus impeller 13 drives flowing of water.This driver has according to load variations and the automatic characteristic adapting to that regulates.Driver can become permanent torque, permanent rotating speed or mixed mode according to Demand Design.
Water pump inside is provided with water flow channel, and when pump working, because the effect of pressure reduction, water is pressed certain orientation and flowed, and the heat of the generations such as stator 2 and metal-oxide-semiconductor 7 is taken away.Aforementioned water flow channel comprises the gap between rotor 3 and metal cylinder 4, the gap at stator 3 centers etc.
During normal work, rotor 3 is surrounded by water, and water pump itself both can, in water, also can leave the water surface and use.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, also can make the conversion of a lot of forms, within these all belong to protection of the present utility model.
