The utility model is characterized in that the main shaft 5 of an electric motor is provided with a fan 4, or a rotor 6 is provided with blades 4; the fan 4 and the blades 4 rotate along the rotor 6; the periphery of the shell 2 of the electric motor is provided with a heat radiation air pipeline 1; the air pipe is arranged on the upper cavity 3 and the lower cavity 8 of the electric motor; the air flows in the cavities of the electric motor through the air pipe; the shell of the electric motor 2 and the heat radiation air pipe 1 are cooled by outside water. The utility model has the advantages that the heat radiation of the electric motor is enhanced; the heat distribution of the interior is uniform; the temperature of the most hot point is reduced; the service life of the electric motor is extended; the utility model solves the problem of the heat radiation of the electric motor of the large-scale immersible electric motor.
Description
The utility model relates to a kind of submersible motor that installs heat dissipation wind channel additional.
Along with the development of water conservancy, be increasing to the demand of Submerged Motor Pumps, and develop that it is widely used in industrial or agricultural transporting water, urban water supply and sewerage and water diversion project to high-power direction.Submerged Motor Pumps mainly partly is made up of submersible motor and waterpower.The structure of waterpower part belongs to existing mature technology, as the various hydraulic parts of Asia-Pacific, Jiangsu pump industry group production.And submersible motor is along with the increase of power, motor stator, the corresponding increasing of root diameter, heat radiation is an a great problem, existing submersible motor dispels the heat in water by motor casing always, so the stator radiating condition that contacts with casing is better, but an air gap is arranged between rotor and stator, and the outside transmission of rotor heat only relies on the heat radiation of stator and does not have other heat dissipation, so heat radiation is very difficult, it is very inhomogeneous to make that internal heat distributes, easily produce heat spot, thereby the influence insulation influences electrical machinery life.
The purpose of this utility model is to make high-power submerged motor that good radiating condition can be arranged, and motor is not burnt because of heating.
Realize that the above-mentioned purpose technological scheme is: this submersible motor is made up of rotor 6, stator 7, main shaft 5, motor casing 2, heat radiation airduct 1, fan 4.Fan 4 is housed on the electric machine main shaft 5, rotates with rotor 6, heat radiation airduct 1 is housed around motor casing 2, airduct is opened on motor epicoele 3 and cavity of resorption 8.Motor casing 2 cools off with the water on heat radiation airduct 1 outer boundary.
The utility model has the advantages that the heat radiation of having strengthened motor, it is comparatively even to make that internal heat distributes, and has reduced the temperature of hottest point, and electrical machinery life is prolonged.Solved the motor radiating problem of large-scale electric underwater pump.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 2 is the sectional view of accompanying drawing 1.
As depicted in figs. 1 and 2, heat radiation airduct 1 is opened on motor epicoele 3 and cavity of resorption 8, its cross section can be arbitrary shape, for example circular, make the upper and lower chamber of motor become the integral body that communicates, on electric machine main shaft 5 (rotor 6 tops), adorn a fan 4, also can directly be loaded on upper rotor part 6, with rotor 6 rotations, hot air is blowed to diametric(al).Hot air turns cold after meeting motor casing 2, density increases, add fan 4 and blow out the pressure that air-flow forms, air is descended along heat radiation airduct 1, so in motor cavity, form air flow channel, hot air is cooled off in heat radiation airduct 1, take away heat when entering 6 of stators 7, rotor more again, motor casing 2 cools off with heat radiation airduct 1 outer boundary water, make the motor internal heat distribution comparatively even like this, the temperature of hottest point and the difference of mean temperature are greatly reduced, avoided motor to influence machine life because of heat spot burns out.
