Abstract
The utility model provides a technical proposal of a full plastic mini-sized water pump which has low manufacture cost and good using effect. The scheme is characterized in that a single-phase alternating current hydromagnetic synchronous micromotor is used in the motor, and the pump casing is arranged on the machine base plate of the motor; an eccentric sleeve is fixed on the out shaft of the motor in the pump casing and an impeller is sheathed on the eccentric sleeve; a sealing sleeve is arranged on the out shaft of the motor between the impeller and the motor base.
Description
The utility model relates to the flow of fluid pump, especially a kind of overall plastic micro pump.
Existing micro pump all needs single-phase ac power supply, so mostly the motor that uses is complexity of structure, therefore the mini-sized shaded pole motor that cost is higher, makes the manufacture cost of micro pump integral body improve, and is difficult to be adopted widely.
The purpose of this utility model is exactly at the high problem of manufacture cost in the prior art, and provides a kind of cost low, and using effect is good, all adopts the overall plastic micro pump technological scheme of working of plastics except that motor and fastening piece.
For clearly demonstrating the structural feature of this programme, now by a specific embodiment, and in conjunction with its accompanying drawing, the technical characteristics of this programme is described in detail.
Accompanying drawing 1 is the utility model embodiment's a part sectional structure schematic representation.
As can be seen from Figure; the overall plastic micro pump of this programme has a pump case 2 that has water outlet 8 and water intake 9; this pump case 2 is loaded on the motor seat board 5 of motor 4; what described motor 4 adopted is the single-phase AC permanent-magnet synchronous micromotor of having applied for the Chinese patent protection; the shaft 1 of motor stretches into the inner chamber of pump case 2; and on Motor Shaft 1 fixing eccentric bushing 7 of suit, suit water pump vane 3 then on this eccentric bushing 7.In addition, on the Motor Shaft 1 between impeller 3 and the motor seat board 5, stuffing box gland 6 is housed also, in order to the transmission medium and the motor of water pump are isolated.On the stator coil case of motor 4, connecting terminal of motor 10 is housed, with the input power supply.The micro pump of this programme, except that motor 4 and used fastening piece, other part all can adopt plastics to be used as material, so this micro pump can become the micro pump of full-plastic.
Owing to adopted simple in structure and single-phase AC permanent-magnet synchronous micromotor that efficient is high in this programme, so the pumping capacity of water pump is strong, the MEDIA FLOW momentum is big, all to adopt plastics except that motor and fastening piece be raw material to make-up water pump again, makes the manufacture cost of whole water pump reduce, and is suitable for wide model and uses.In this programme, the eccentric bushing of on Motor Shaft, having gone back suit, its purpose is to utilize off-centre to overcome the dead angle that motor rotates, and motor is started easily.This shows, the utility model compared with prior art, its effect is conspicuous.
Embodiment illustrates in technological scheme, so no longer repeat.
