Description
The present invention relates to a kind of multipurpose asynchronous motor axial-flow pump.
It both can convert electrical energy into mechanical energy and use as motor, and the rotation blade fluid pump that can be used as conveyance fluid again uses.
The basic structure of existing asynchronous motor is by fixing stator, and rotor that freely rotates and marginal air gap are formed.The main body of stator is unshakable in one's determination and is embedded in the staor winding in the equally distributed groove of circle in the iron core that the main body of rotor is iron core and rotor shaft.Rotor covers under the supporting of bearing in two side ends, is suspended in the stator cavity.Leave suitable air gap between stator and the rotor.Feed Ac, rotor rotates outputting power along the direction in magnetic field under the effect of rotating magnetic field.Variation asynchronous motor according to rotor mainly is divided into: squirrel-cage, Wound-rotor type, three kinds of solid formulas.For adapting to the different environment and the needs of purposes, it is different to derive form again, the anomaly asynchronous motor that purposes is different.The defective of existing asynchronous motor is: purposes is single, can only use as prime mover.The heat radiation of motor is that the fan that is mounted on the motor external electric arbor realizes that effect is undesirable.When the traffic overload electric current of motor strengthens, burn easily.Sealed insulation is undesirable.Waterproof and dampproof, anticorrosion, explosion-proof performance is relatively poor.Particularly during the supporting use of asynchronous motor and rotation blade fluid pump, its defective is just more outstanding: motor need pass torque to the fluid pump of attaching troops to a unit by coupling.The both is fixed on same rigid foundation or framework, the cylindrical shell.Because pump shaft exposes, and is easy to generate and sews, and influences the efficient of pump.And equipment volume is big, heavy, and working link in service is many, break down easily.For overcoming above-mentioned deficiency, Chinese invention patent discloses a kind of pump integrating electric motor with vane wheel numbers No. 87108186.This invention is integrated motor and impeller.There is impeller the rotor inboard, and the outside is made up of the cylindric solid of rotation that the excitation material of excitation effect constitutes.Cancelled pump shaft, rotated as rotor with solid of rotation.The acting in conjunction of blade and cylinder produces the lift conveyance fluid.Its defective is: can only use as pump, can not use function singleness as motor.
The purpose of this invention is to provide a kind of multipurpose asynchronous motor axial-flow pump that asynchronous motor and pump are combined as a whole.It both can use as motor, can be used as axial-flow pump again and used.
Asynchronous motor axial-flow pump as shown in Figure 1, by support 15, be installed in support inner stator 14, be suspended in the rotor body output terminal in the stator cavity, the supporting mass 3 of suction side, and be contained in axial thrust bearing 4 in the bearing support, bearing shim 5, radial bearing 6, pto 7, pto lid 8, bearing gland 9, guide vane 10, packing ring 12 constitutes, it is characterized in that blade with rotor and axial-flow pump is combined as a whole or is combined into fabricated rotor body, this rotor body is by pto 7, supporting rib 11, rotor body wall 13 and rotor body lift force blade 16, rotor body guide vane 19 constitutes, and rotor body is with single magnetic material such as steel, iron or composite magnetic; Copper steel, aluminum steel are made, and pto and external isolation sealing prevent to leak, and the iron core of stator becomes an integral body with three phase windings with the insulated enclosure material package, to improve the sealed insulation performance of this machine, plays waterproof, protection against the tide, anticorrosion, explosion-proof; The sleeve rotor body is suspended in the stator cavity under the supporting of the bearing on the supporting mass 3, and staor winding feeds alternating voltage, produces rotating magnetic field, and rotor body moves in a circle along the magnetic field sense of rotation.
The present invention is characterized in that compared with the prior art the function that had both had motor uses as prime mover, has the function of rotation blade fluid pump again, uses as pump; Because blade and rotor are combined as a whole, the therefore liquid that is transferred and enter the interior air of machine is entered by the entry end of this machine, in rotor body, exports from outlet end.Its advantage is: the phenomenon of stopping a leak, and simplify the structure and reduce the chance that breaks down, reduce maintenance expenses, reduce cost; Since the power loss that has reduced the friction of bearing packing and pump shaft and stopped a leak and cause, the efficient of raising pump; Liquid that the heat that produces in the machine is transferred and the absorption of air that enters, and outside the discharge machine, the equipment that effectively guarantees normally moves; When it uses as axial-flow pump, can be used as face-pumping use usually, also can be used as deep-well pump and use, to put into water and can be used as submersible pump, the diving deep-well pump uses.Can also use as the Powerpush Unit of means of transportation in the water surface, the water, reduce noise.
