Abstract
The utility model relates to a heat radiating device for an oil-submersible motor. The heat radiating device is characterized in that an impeller is installed on a hollow motor shaft which is lengthened, and a radiator shell body with heat radiating fins is arranged below the impeller. High-temperature motor oil in the motor can be sucked into the radiator shell body by the impeller to be carried out heat radiation, and then the low-temperature motor oil of which the heat is radiated is pressed into the hollow motor shaft to be thrown into the motor through an oil throwing hole, so that the heat of the motor is absorbed. The heat radiating device can accelerate the flow of the motor oil, and can enlarge a radiation area according to the repeated circulation; therefore, the heat radiating device can accelerate the heat radiation of the motor, and can extend the service life of the motor. The heat radiating device for an oil-submersible motor can be widely used for occasions using oil-submersible motors.
Description
The utility model relates to a kind of submersible electric machine with oil heat abstractor, belongs to a kind of of motor radiating device.
At present, the submersible electric machine with oil heat radiation is by the natural circulation of dynamo oil between bore of stator and hollow shaft the heat that motor produces to be passed on the motor housing, again by motor housing with heat diffusion in well liquid, flow by well liquid at last heat is passed away, therefore, the motor radiating effect depends on motor housing size, the dynamo oil flowing velocity in motor and the flow velocity of well liquid.Float amount submersible electric pump and in, discharge capacity cause for a short time and flow velocity slow, this just causes motor to produce heat and can not in time distribute, and motor is at high temperature worked reduction of service life always.
The purpose of this utility model is exactly that a kind of a kind of submersible electric machine with oil heat abstractor that quickens the submersible electric machine with oil heat radiation is provided in order to overcome above-mentioned the deficiencies in the prior art.
The technical solution of the utility model is such realization: radiating shell is respectively with the upper and lower joint of thread connection, and all seal with sealing ring, be equipped with in the top connection lead shell, impeller and under lead shell, hold-down ring holds out against in top connection and with each part of dress in it successively with thread connection, penetrate between the core motor axle of heat abstractor and the upper and lower joint alignment bearing is housed, impeller also can rotate with key connecting core motor axle thereupon, has oil-through hole in the lower contact.
Above-mentioned submersible electric machine with oil heat abstractor, its impeller are receded disk impeller, and the centre has the hole that can pass the core motor axle, and the periphery wall of radiating shell is provided with fin or directly is smooth cylinder-like structure.
Above-mentioned submersible electric machine with oil heat abstractor, its impeller can together rotate with the core motor axle, because centrifugal action can produce swabbing action to the dynamo oil in the motor when wheel rotation, and can produce pressure to the dynamo oil of radiating shell inner chamber.
The utility model compared with prior art, because impeller together rotates and can produce swabbing action to the oil of the high-temperature electric machine in the motor with the core motor axle, so can accelerate flowing of dynamo oil, again because radiating shell is provided with fin, strengthened area of dissipation, so finally can quicken motor radiating, prolong motor useful life.
Accompanying drawing 1 is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
In the accompanying drawing 1, the core motor axle 12 that band gets rid of oilhole 1 is housed in the motor 2, and the common core motor axle of this axial ratio has been made lengthening so that connect heat abstractor.Heat abstractor is upper and lower respectively with thread connection top connection 5 and lower contact 15 at radiating shell 11, and all with sealing ring 7 sealings, lead in top connection 5, being equipped with successively shell 6, impeller 8 and under lead shell 9, hold-down ring 10 compresses with thread connection top connection 5 and with each part of dress in it, impeller 8 connects with key 16 with core motor axle 12, be equipped with alignment bearing 4 between top connection 5, lower contact 15 and core motor axle 12, lower contact 5 is provided with oil-through hole 13.
When using this heat abstractor, at first with the top connection 5 of radiator and motor housing 3 with thread connection, and with sealing ring 7 sealings.During motor 2 work, impeller 8 together rotates with rotor, top connection 5 and in each part of dress, radiating shell 11 and lower contact 15 all keep motionless.Because impeller 8 together rotates with core motor axle 12, runner on it is because centrifugal action can produce swabbing action to the high-temperature electric machine oil that plays insulation and lubrication in the motor 2, can produce pressure to the oil of the low temperature electric machine that has dispelled the heat in the radiating shell 11 again, high-temperature electric machine oil in the motor 2 is just through the runner of impeller 8 like this, the runner of leading shell 9 down enters radiating shell 11 inner chambers and in this heat radiation, low temperature electric machine oil after the heat radiation is up always along axis hole 14 through oil-through hole 13 backs under the pressure effect that impeller 8 produces, get rid of into motor 2 inner chambers to getting rid of oilhole 1, the heat that absorbs motor 2 generations in motor 2 is again through impeller 8 sucking-offs, so repeatedly, the heat of motor 2 can be distributed.
The utility model is simple in structure, easy to use, rapid heat dissipation, submersible electric machine with oil heat radiation is had good effect, can prolong motor useful life.
