Abstract
The utility model relates to a motor used for underwater work, particularly a screening type diving motor. The utility model causes a stator body to be completely sealed via a screening sleeve barrel made of magnetic conduction material sheathed on the inner side of the stator body through a seal structure and a detachable seal mechanism of a casing of the motor, however, common polyester enamelled wires can be used, and thereby, the volume of the motor is reduced, the cost is low and the efficiency and the service life are enhanced. The utility model is suitable for common farmland drainage and irrigation and can also be used for extracting warm groundwater and industry hot water.
Description
A kind of motor that is used for underwater operation specifically is the protected type submersible motor.This motor comprises sand-throwing ring, rotor block, stator body, bearing, bearing pedestal, oil sealing, screening arrangement and motor housing composition.
Present widely used agricultural submersible motor, major part is a Water for wet type.Its stator body is to be formed by the coiling of polyethylene nylon sheath wire waterproof wire, and the water-fast insulating layer thickness of polyethylene nylon sheath wire is generally the 1.05-0.86 millimeter, thereby the submersible motor design volume is big, and material usage is many, the cost height, and efficient is low, and the life-span is short, and temperature capacity is poor simultaneously.At the industrial shield electric machine that is useful under the particular surroundings, be integrally welded between stator body and the housing, non-dismountable, the manufacturing process complexity, maintenance is inconvenient; Its housing material is to adopt anti-corrosion materials such as stainless steel or epoxy resin to make, and causes motor gas-gap excessive, influences motor performance.Therefore, the industry shield electric machine is not suitable for the farmland discharging-irrigating use at present.
The design the purpose of this utility model is to be to adopt new shielding structure, and stator body is sealed fully, reaches stator body and does not make moist, can be easy to remove and repair again, adopt the conventional polyester enamelled wire, reach and reduce volume, reduce cost, raise the efficiency, improve the purpose in life-span.
The utility model can be realized by following measure:
This submersible motor is by comprising that sand-throwing ring, stator body, rotor block, bearing, oil sealing, screening arrangement and motor housing body form.Its characteristics are that screening arrangement is the shroud sleeve of being made by the permeability magnetic material that is sleeved on the stator inboard, is detachable by hermetically-sealed construction and motor housing and connects.Its hermetically-sealed construction is to make seal welding by shroud sleeve and end casing, and shielding between worn-out sleeve and the annular groove end casing mating surface has zero RunddichtringO, and annular groove end casing lateral surface cooperates with motor housing, is provided with zero RunddichtringO between the mating surface.
The design also can realize by following proposal: be provided with homo-pressed film in the annular groove of the annular groove end casing that has pressure guide hole, be hermetically sealed with this annular groove end casing and contact, be filled with coolant in stator interior and homo-pressed film inboard.
The stator punching notch height of above-described submersible motor can be decreased to zero.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.Sand-throwing ring, bearing (9), bearing pedestal, rotor block (12), oil sealing and motor housing (15); Basic close with existing submersible motor structure, be not described further at this, and its structure that changes part is such:
End casing (16) and shroud sleeve (2) seal welding.Between end casing (16) and motor housing (15) mating surface zero RunddichtringO (13) is arranged, and by spring collar (1) location.Cooperate at the annular groove face of other end shroud sleeve (2) with annular groove end casing (7), zero RunddichtringO (8) is arranged between the mating surface, zero RunddichtringO (11) is arranged between the mating surface of annular groove end casing (7) outer surface and motor housing (15), be provided with the spring collar location again.
For preventing " breathing " phenomenon that motor temperature rise in service is caused so that cause steam or moisture to enter the homo-pressed film (10) that motor is provided with by sealing device.The outer edge of homo-pressed film (10) is sealing with the annular groove bottom surface of annular groove end casing (7) and contacts.By buting iron (5), annular foundary weight (6) is pushed down homo-pressed film, and buting iron (5) can be the threaded back-up ring in edge or zero type back-up ring or fan-shaped band iron.Annular foundary weight (6) can be two annular rings or the anti-ring groove shape iron of adorning.
In the stator shielding cavity, be filled with coolant, its objective is the raising heat-sinking capability, make the motor internal each point temperature difference equal substantially.This coolant can be used machine oil, transformer oil or hot melt medium, as industrial paraffin wax.The motor of low capacity can not adorned coolant and get final product with air cooling.Coolant adds by the oiling screw (14) that is located on the end casing (16).
The material of homo-pressed film can be Waterproofing/oilproofing rubber or rubber aluminium pool, plastic composite.
The punching notch height of this submersible motor stator can be decreased to zero.
Adopt the utility model to solve stator and seal fully, sealing device is again a demountable structure, again by adding pressure-equalizing device; Then can realize the purpose of this utility model, that is: adopt common enamelled wire, can obviously reduce motor volume and weight, reduce cost.Owing to be full of coolant in the stator body, improve heat dissipating state, improve motor useful life.Because housing adopts permeability magnetic material, as a motor magnetic circuit part, it is excessive to have solved the shield electric machine air gap made from non-magnet material, the problem that efficient is lower.The leakage flux of housing can limit the starting current of motor simultaneously, prevents to cause the phenomenon of burning motor owing to starting current is excessive, has improved the overload capability of motor.
And the work temperature rise of this structure can be used under 40 ℃ of situations of water temperature, as groundwater abstraction, industrial hot water etc. than about 40 ℃ of general submersible motor raisings.
