One water injection hole 9 communicates with cooling tube 1.It is the working media of submersible motor, generally cold water on the outside of cooler.So, cooler
The hot water of middle flowing carries out heat exchange by cooler and outside cold water, the water of cooler internal flow cool cold
But.By the first water injection hole 9, water is injected into cooler, for cooling down motor.After water enters cooler, enter casing 14 again
In inner chamber, heat caused by the component workings such as rotor and stator is taken away.Then water sequentially enters the water in water jacket 8, casing 14
Road and cooling tube 1, are finally flowed back in cooler casing inner chamber, are circulated with this.Wherein, when the water for absorbing heat enters in water jacket 8
When, you can heat exchange is carried out with the medium outside submersible motor, and heat exchange is continued for, and heat exchange is continued until that water enters
Before entering impeller.Due to the heat exchange of long period, when water is again introduced into impeller, cold water is become by hot water, carried out next time cold
But circulate.
In above-described embodiment, the cooler also includes magnet steel 4, and magnet steel 4 is fixedly connected in shell inner cavity.It is existing latent
Hydroelectric machine can not automated cleaning due to steel cuttings caused by motor pivoting friction and other rigidity impurity, if motor when rotating not
These steel cuttings impurity are removed in time, it is easier to cause the friction between motor rotatable parts, so as to produce more steel cuttings impurity,
So move in circles, the friction that certainly will increase motor reduces the service life of motor.In the submersible motor that the present embodiment provides,
Cooler absorbs due to steel cuttings caused by friction between motor rotatable parts built with a number of magnet steel 4, cleaning of electricity
The running environment of machine, so as to reduce the friction between motor rotatable parts, the service life of motor is extended, reducing need not
The economic loss wanted.After running a period of time, cooler can be opened, remove magnet steel 4 and clear up the steel cuttings adhered to above
Totally, so as to ensureing the cleaning of motor operation environment.The process succinctly facilitates, easily operation.

Runner fills motor, after water fills, seals the first water injection hole 9 with O-ring with screw, you can use submersible motor.Diving electricity
Machine at work, the high-speed rotation under the drive of rotor of impeller 5 so that lower leading axle bearing inner chamber pressure increase, promote current
Along the direction of arrow flow direction motor inner chamber in Fig. 1, clean water in motor cavity is acted on to continuing to flow through electricity due to pressure
Stator, the rotor of machine, while flowing through stator, rotor, the heat that sends when taking away motor work, finally on motor top along arrow
Head direction outflow motor chamber, flows into water jacket 8, cooler is flowed to by water jacket 8.In the process, the water of heat is carried in water jacket 8
Heat exchange is produced with the medium outside submersible motor, the heat of motor internal is transmitted to the medium of outside, is used in cooling
Cleaning coolant-temperature gage lowers.The clean water that temperature declines flows into cooler along the direction of arrow in Fig. 1, and distribution is provided with cooler
The water guide set and magnet steel 4 of water-guiding hole.The effect that clean water is covered due to water guide, impeller intake is flowed to along the arrow in Fig. 1, so
Sent out by impeller pressurization and circulated next time again afterwards.
Further, since magnet steel 4 is installed in cooler, internally while water circulation, because motor internal rotates
Steel cuttings caused by friction is when flowing through near magnet steel 4, by the strong absorption of magnet steel semi-finals, so as to cleaning of the cooling water ring of motor internal
Border, the friction between each rotatable parts of motor is reduce further, extend the service life of rotor part.So repeatedly, i.e.,
Submersible motor can be radiated, while clean the rigidity impurity in cooling water.
In the submersible motor of above-described embodiment, water guide set 2 around and bottom is provided with circular hole, by water guide set 2 front and
The water that surrounding flows into, eventually pass through and flow to impeller 5 around the magnet steel of 2 bottoms of water guide set.Current are pressurizeed by impeller 5
Forced circulation.Magnet steel 4 absorbs steel cuttings caused by friction between each rotatable parts and natural rust and caused anvil cinder, cleaning
The impurity of recirculated water, serves the effect of cleaning, ensure that the normal operation of motor each several part, and extend motor uses the longevity
Life.Meanwhile impeller 5 and armature spindle synchronous rotary, forced circulation has been carried out to cooling water, has accelerated the flowing of current, so as to add
The fast speed of motor radiating, improves cooling effectiveness, reduces the temperature of motor operation, extend the service life of motor.
The present invention can not only cool down motor, the running environment of motor internal can also be cleaned, so as to ensure that motor
Long-term safety is run.
