The water circulation cooling structure is particularly suitable for a large-scale mining submersible motor, has simple structure, reduces the welding workload of the outward appearance of the motor, and increases the whole corrosion-resistant capability of the motor; the cooling channel is closer to the heat source and has better cooling/heat dissipation effect; the motor is convenient to install, repack and clean, which can be realized by common technical workers.
Description
Technical field
The present invention relates to the water circulation cooling structure in submersible motor field, particularly a kind of submersible motor.
Background technology
In all power grades especially heavy-duty motor running, all can produce a large amount of heat, in order to improve electric efficiency and to prolong electrical machinery life, the designer discharges the heat that motor produces by corresponding cooling or device.For submersible motor, self-loopa in motor reaches the heat radiation purpose to water as coolant usually.The submersible motor that uses is processed with heat radiation water channel and radiating ribs above the excircle of support at present, and the lower axial end of rotor is equipped with the circulation water wheels.During machine operation, water wheels rotate, and circulating water flow enters from the lower end, gap between rotor and the stator, and flows out from the upper end.The current that flow out from motor upper end are through heat radiation water channel flow direction motor bottom from top to bottom, in the heat radiation water channel from top to bottom flowing water flow with the outside current of heat transferred, thereby realize the heat radiation of motor.Because this cooling means mainly realizes by heat radiation water channel and the radiating ribs that base outer protrudes, is referred to as outer water circulation cooling structure for the time being.
In a single day this outer water circulation cooling structure meets with heavy-duty motor, has just strengthened the welding job amount of motor outer surface; Because the motor periphery is rough and uneven in surface, makes that the motor surface is perishable; Cause inconvenience in addition cleaning, the maintenance of motor.
And for example disclosed Chinese patent CN03277388.9: water-stop structure in a kind of stator cooling of electric main shaft.In electric main shaft the inside rotor and stator are arranged, in the stator outside sleeve and cooling-water duct are arranged, it is characterized in that: cooling-water duct is arranged between the inwall and interior water proof cover of sleeve, and the surface that water proof overlapped in shape was arranged in the shape of a spiral, interior water proof cover is installed on the stator outside, and the thickness of interior water proof cover is littler than the thickness of sleeve.Intake-outlet is arranged in the wall of sleeve, and with cooling water channel UNICOM.Between the contact-making surface of the two ends of interior water proof cover and sleeve, sealing ring is set.This device can further improve the cooling effect of stator, simplified processing process, the useful life of prolongation motor.
But above-mentioned cooling-water duct is far away apart from the motor thermal source with that cooling water channel is set on electric machine stand is the same; And increased this one procedure of dismounting cooling jacket again.
Summary of the invention
Purpose of the present invention provides a kind of simple in structure at existing weak point in the above-mentioned prior art just, and good cooling results is aesthetic in appearance, is particularly suitable for the interior water circulation cooling structure of large-scale mine submersible motor.
Purpose of the present invention can realize by following technique measures:
Water circulation cooling structure in of the present invention comprises circular cylindrical cavity, cooling water channel that bosh, support and stator on the motor stator form, and cooling water channel is that bosh and electric machine stand amalgamation form.
Especially, bosh is that the cylindrical at stator punching is processed to form, the quantity of bosh is that the cross sectional shape of bosh does not limit, and generally is designed to square groove for the ease of processing by submersible electrical power size, heat dissipation capacity, the decision of motor cross-sectional area.
As preferably, bosh should with the axially parallel of submersible motor, bosh is evenly distributed on stator, can the function that flows, do not have the cooling blind area unimpeded from top to bottom in cooling water channel be good to realize water.
As preferably, the submersible motor support is level and smooth drum, no independent cooling water channel, radiating ribs.
Operation principle of the present invention is as follows:
Water circulation cooling structure in of the present invention, under the submersible motor normal operation, the water in the base is forced to enter from the lower end, gap between rotor and the stator, and flows out from the upper end.The water that flows out from motor upper end is through cooling water channel flow direction motor bottom from top to bottom, in cooling water channel from top to bottom flowing water flow with the outside current of heat transferred, thereby realize the heat radiation of motor.
Beneficial effect of the present invention is as follows:
Adopt the present invention, especially for the large-scale mine submersible motor, the bosh that its unique motor stator punching is processed to form, more close thermal source, cooling/radiating effect is more excellent; Support is level and smooth drum, saves radiating ribs, has significantly reduced the welding job amount of motor outer surface; The outer body of level and smooth motor has more improved the whole corrosion resistance of motor; Motor is installed, overhauls, is cleaned conveniently, and average skilled worker just can realize.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention;
Fig. 2 is a stator structure schematic diagram of the present invention.
Be labeled as among the figure: 1: stator; 2: cooling water channel; 3: support; 4: key; 11: bosh.
Embodiment
The present invention is further described below with reference to embodiment (accompanying drawing):
As shown in the figure, interior water circulation cooling structure of the present invention comprises circular cylindrical cavity, cooling water channel 2 that bosh 11, electric machine stand 3 and motor stator 1 on the motor stator 1 form, and cooling water channel 2 is that bosh 11 forms with electric machine stand 3 amalgamations.Motor stator 1 passes through key 4 and several dowel fixes with support 3.
Under the vertical working condition that pulls the plug of motor, the water in the base is forced to enter from the lower end, gap between rotor and the stator 1, and flows out from the upper end.The water that flows out from motor upper end is got back to base through cooling water channel 2 flow direction motor bottom from top to bottom.In cooling water channel 2 from top to bottom flowing water flow with the current outside the heat transferred motor, thereby realize the heat radiation of motor.
