Abstract
The utility model discloses a single-phase water cooling type submerged pump. The primary structure is that an electric motor (18) is communicated with the water inlets of the suction ends of a water chamber (4) and an impeller (3) through a water through hole (17), and the electric motor (18) is fully filled with the medium of water. A filter screen (16) is arranged at the water inlet of the suction end of the impeller, and a filter pad (15) is arranged between the top face of the water through hole (17) and the bottom face of the impeller (3), preventing the foreign matter in the water from entering the hollow cavity of the electric motor to damage the electric motor to make the pump fail. The utility model adopts the water cooling method.
Description
The utility model belongs to water pump, and particularly impeller and live axle are direct-connected, and pump is whole.Body all immerses the single-phase water cold type submersible pump in the aqueous medium.
The submersible pump of Cai Yonging adopted the oil immersed type structure of sealing mostly in the past.Owing to make and use, sealing was very easily lost efficacy, and caused the motor leakage of oil, and insulation breakdown can not normally use, the leaking and cause the pollution of water resources of insulating oil.And to check all before each the use and the sealing situation of motor more renew insulating oil that the complicated operation cost is also high.
The purpose of this utility model is the oil immersion insulation system that changes sealing, provides a kind of direct with the water-cooled water-cooled submersible pump of medium.Because do not use sealing configuration, thereby reliable operation, the water resource pollution that insulating oil leaks and causes also successfully prevented.Cost descends to some extent simultaneously.
The purpose of this utility model reaches like this, with the structural similarity of the submersible pump of prior art, is made up of motor, hydroecium, impeller, outlet pipe and water outlet etc.But, the inner chamber UNICOM of water port and motor is arranged on the bottom surface of hydroecium, the inner chamber that makes motor through the water port to the suction side of impeller and water intake and extraneous medium UNICOM (during work and water, when not working and air).On the water intake of the suction side of impeller, a contaminant filter net is housed.Above the bottom of hydroecium and the water port between the impeller, a filter pad is arranged.Impurity in the anti-sealing of above-mentioned measure enters motor cavity.The stator of motor is set in the structure in the stator slot by the coiling of nylon water-proof wire, promptly reaches the purpose that the utility model proposes by above narration.
The utility model has the advantages that,, need not add insulating oil owing to adopted the unsealed form that is communicated with of motor cavity with extraneous medium, thereby the problem of not having draining do not exist oil to the pollution of water resources, and the stator line of motor is made by the nylon water-proof wire, life-span is long, and motor is difficult for heating in water.Use the back maintenance convenient, and the insulating oil of consume expensive not.Economical and practical.Its deficiency is to use in the higher aqueous medium of impurity content.
Description of drawings: accompanying drawing is a structure front section view of the present utility model.In the accompanying drawings: (1) water outlet, (2) outlet pipe, (3) impeller, (4) hydroecium, (5) bearing, (6) oil sealing, (7) nut, (8) bolt, (9) body, (10) stator, (11) rotor, (12) rotor shaft, (13) base, (14) oil sealing, (15) filter pad, (16) filter screen, (17) water port, (18) motor.
Below in conjunction with accompanying drawing specific embodiment is described in detail.With reference to accompanying drawing: motor (18), hydroecium (4), impeller (3), outlet pipe (2), water outlet (1) constitutes submersible pump of the present utility model jointly.The inner chamber of motor (18) is by water port (17), through hydroecium and to the suction port of the suction side of impeller (3) and extraneous medium UNICOM.Water outlet (1) is a garden Guan Yiduan and draining pipe grafting (drawing among the figure), one end is fixedlyed connected with outlet pipe (2), interior lumen UNICOM, and outlet pipe is a herringbone structure as shown in FIG., the lower end is fixed on the hydroecium, with the drain opening formation water passage on the hydroecium.
Impeller (3) suction side suitable for reading by filter screen, covers on it as shown in the figure, on the water intake topped filter screen (16) afterwards, the impurity in the water can not enter in the hydroecium (4) promptly by strainer filtering, the contaminant filter net is fixed by coupling in case filter inefficacy.
On the lower bottom plane of hydroecium (4), have the inner chamber UNICOM of water port (1) and motor (18), in order to prevent to enter once in a while the inner chamber that impurity in the hydroecium enters into motor, on the water port and the spatial design between the impeller (3) filter pad (15) is arranged, enter motor internal to stop the impurity in the hydroecium.
Rotor of motor (11) and stator (10) and axle all are immersed in the aqueous medium, and in order to prevent to damage insulation, stator (10) is set in the stator slot by the coiling of nylon water-proof wire.Motor stator axle (12) is supported by pair of bearings (5), bearing is isolated by axle envelope (6) and (14) and aqueous medium, in case damage of bearings and lubricating oil leak, motor (18) and hydroecium (4) are by bolt (8) and nut (7) housing (9) with motor, base (13) and hydroecium (4) link into an integrated entity, connect outlet pipe (2) above the hydroecium again, the top water outlet (1) that connects again of outlet pipe (2).It promptly is whole appearance structure of the present utility model.
Because the utility model adopts complete water-immersed water-cooled, each component is removed outside the motor stator axle, and machining accuracy all requires not tight (because need not add tight sealing).If but its deficiency is not in WATER AS FLOW MEDIUM, when not having cooling medium, does not allow the energising operation.Motor of the present utility model can be used three phase AC induction machine, and is all right, and goes out the needs that preceding rural power lacks the area in order to satisfy China, uses single-phase (220 volts-180 volts) AC motor, to enlarge its using scope.
If be necessary that submersible pump of the present utility model can also merely be applied to, in the medium of kerosene, diesel oil and other non-corrosiveness impurity, be unsuitable for pumping crude oil and the explosive medium of corrosion.
