Description
Technical Field
The utility model relates to a motor technology especially relates to a technique of self-cooling deep-well pump motor.
Background
The existing motor is provided with a heat radiation fan at a rear end cover, the fan can rotate along with a rotor when the motor runs, air is discharged by utilizing a simple air deflector, the structure of the rear fan is characterized in that air flow enters an inner cavity of a shell from the front end of the motor and then is discharged from the rear end of the motor, the air flow can absorb heat in the inner cavity of the shell in the process of flowing from front to back, but because the air flow flows from front to back, the heat at the front end of the motor can be brought to the rear end of the motor in the flowing process, so that the heat radiation effects at the front end and the rear end of the motor are inconsistent, the heat radiation effect at the rear end of the motor is far different from that at the front end of the motor, and therefore, the motor with the rear fan structure has the defect of poor heat radiation.
SUMMERY OF THE UTILITY MODEL
To the defect that exists among the above-mentioned prior art, the utility model aims to solve the technical problem that a self-cooling type deep-well pump motor that the radiating effect is good is provided.
In order to solve the technical problem, the self-cooling deep well pump motor provided by the utility model comprises a casing, a stator core and a rotor core which are arranged in the casing, and a front end cover and a rear end cover which are arranged at the front end and the rear end of the casing; the method is characterized in that:
the shell is provided with a plurality of air outlet holes, and fan blades for supplying air towards the directions of the air outlet holes of the shell are fixed at the front end and the rear end of the rotor iron core;
the front end cover is fixedly provided with a front air hopper which is a horn-shaped cover body with a wide front part and a narrow back part and is communicated with the front part and the back part, a narrow opening at the back end of the front air hopper is over against the fan blades at the front end of the rotor core, the front end cover is provided with a plurality of front end air inlet holes, and each front end air inlet hole is positioned at the front side of the front air hopper;
the rear end cover is fixedly provided with a rear air hopper, the rear air hopper is a horn-shaped cover body which is wide at the rear and narrow at the front and is communicated with the front and the rear, a narrow opening at the front end of the rear air hopper is over against the fan blades at the rear end of the rotor core, the rear end cover is provided with a plurality of rear end air inlet holes, and each rear end air inlet hole is positioned at the rear side of the rear air hopper.
The utility model provides a self-cooling deep-well pump motor, from both sides air inlet simultaneously around the motor, air exhaust through the exhaust vent on the casing for both ends can both reach good radiating effect around the motor, have the characteristics that the radiating effect is good.
Drawings
Fig. 1 is a schematic structural diagram of a self-cooling deep-well pump motor according to an embodiment of the present invention.
Detailed Description
The following description will be made in detail with reference to the accompanying drawings, but the present embodiment is not intended to limit the present invention, and all similar structures and similar variations thereof adopted by the present invention should be included in the protection scope of the present invention, and the relations between the numbers of the components in the present invention are shown.
As shown in fig. 1, a self-cooling deep-well pump motor provided by the embodiment of the present invention includes a casing 4, a stator core and a rotor core installed in the casing, and a front end cover 1 and a rear end cover 8 installed at the front and rear ends of the casing 4; the method is characterized in that:
a plurality of air outlet holes 41 are formed in the casing 4, and fan blades 5 for supplying air towards the directions of the air outlet holes 41 of the casing are fixed at the front end and the rear end of the rotor core 7;
a front air hopper 3 is fixed on the front end cover 1, the front air hopper 3 is a horn-shaped cover body which is wide in front and narrow in back and is through from front to back, a narrow opening at the back end of the front air hopper 3 is over against a fan blade 5 at the front end of a rotor core 7, a plurality of front air inlet holes 11 are formed in the front end cover 1, and each front air inlet hole 11 is positioned at the front side of the front air hopper 3;
the rear end cover 8 is fixed with a rear air hopper 9, the rear air hopper 9 is a horn-shaped cover body which is wide at the rear and narrow at the front and is through from front to back, a narrow opening at the front end of the rear air hopper 9 is over against the fan blades 5 at the rear end of the rotor core 7, the rear end cover 8 is provided with a plurality of rear end air inlet holes 81, and each rear end air inlet hole 81 is positioned at the rear side of the rear air hopper 9.
The embodiment of the utility model provides a theory of operation as follows:
when the motor is powered on to operate, the fan blades 5 on the rotor core can rotate along with the rotor core, air in the inner cavity of the shell flows to the air outlet holes 41 of the shell under the action of the fan blades 5 and is discharged from the air outlet holes 41 of the shell, external air can enter the inner cavity of the shell through the front air inlet holes 11 and the rear air inlet holes 81, the flow speed is accelerated after the air is compressed by the front air hopper 3 and the rear air hopper 9, and then the air is sucked by the fan blades 5 on the rotor core, so that an effective air cooling circulation is formed around the use environment of the motor, the temperature of the surface of a stator winding and the surface of a rotor during the operation of the motor can be well taken away, and the motor is fully cooled.
