Abstract
The utility model provides a ventilation structure for a vertically-mounted motor. The ventilation structure comprises a motor base and an axial flow fan. An air inlet of the motor is arranged in the motor base, and the axial flow fan is mounted at the air inlet. A stator and a rotor are mounted in the motor base; a plurality of round holes are arranged in a stator punching sheet and a rotor punching sheet, so as to form an axial ventilating duct; a plurality of square air outlets are arranged at the shaft extending end of the motor base; the axial flow fan is mounted at the end without shaft extending of the motor base; and the ventilating duct is arranged at the air inlet of the axial flow fan. The ventilation structure uses a manner of combining the axial flow fan with the ventilating duct of a ventilation system, so that the problems that the ventilation pressure is decreased due to a long ventilating pipeline can be solved. The heat radiation capacity of the motor can be ensured when the motor is operated in severe working conditions (such as frequent start braking and frequent positive-negative rotating); the problem of motor burning caused by temperature rise can be solved; and a great amount of maintenance cost and a great amount of loss brought by production halt of a production line due to motor maintenance can be saved for a user.
Description
Technical field
The utility model belongs to motor and makes the field, relates to a kind of ventilating system, especially a kind of ventilating system that is used for vertical installation motor.
Background technology
In the prior art, the type of cooling that is used for vertical installation motor is a pipe ventilated.Because the factory building space is big, the pipeline of cooling air process is longer, cause at the pressure of motor air inlet less, bad to the cooling effect of motor.Thereby make motor temperature rise occur, even the fault of burning, the normal operation of whole production line influenced.And this kind motor is all from external import, and maintenance cycle is long, and cost is high, brings tremendous loss to factory.
The utility model content
The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of effective aeration structure is provided; This kind aeration structure still adopts the mode of pipe ventilated, but has increased axial flow blower at the motor air intake, makes whole ventilating system more reasonable, and is better to the heat radiation of motor.
To achieve these goals, the utility model adopts following technical scheme:
A kind of aeration structure that is used for vertical installation motor comprises electric machine stand and axial flow blower; Electric machine stand is provided with the motor air inlet, and this air inlet is equipped with axial flow blower.
The utility model further improves and is: said aeration structure also comprises air pipe, the air inlet of the air outlet connection shaft flow fan of air pipe, and the air outlet of axial flow blower is communicated with the motor air inlet.
The utility model further improves and is: stator and rotor are installed in the electric machine stand; All offer some circular holes on stator punching and the rotor punching, form the axial ventilation road.
The utility model further improves and is: electric machine stand shaft extension end is provided with a plurality of square exhaust vents; Axial flow blower is installed on the non-shaft stretching end of electric machine stand, and the air inlet of axial flow blower is equipped with air pipe.
The utility model further improves and is: the air inlet place of air pipe is equipped with air-blast device.
With respect to prior art, the utlity model has following advantage: the ventilating system that the utility model adopts is the mode that axial flow blower combines with pipe ventilated; It is long to have solved air pipe, the problem that causes ventilation pressure to descend; Guaranteed the heat-sinking capability when motor moves under bad working environments (frequently playing braking, frequent rotating) condition; The problem that has solved the electric machine temperature rise height even burnt; The huge loss of having saved a large amount of maintenance costs and production line having been stopped production bring owing to electrical machmary maintenance for the user.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the motor ventilation sketch map.
Wherein: 1 is support; 2 is stator; 3 is rotor; 4 is axial flow blower; 5 is air pipe.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
See also shown in Figure 1; The utility model is applicable to the aeration structure of vertical installation motor; Be on the architecture basics of existing vertical installation motor, carry out improved; Therefore, it has comprised that all of existing vertical installation motor must parts: electric machine stand 1, be located at the air pipe 5 of the inner stator 2 of electric machine stand 1 and rotor 3, support afterbody etc.The improvements of the utility model are that the place has increased axial flow blower 4 at the motor air inlet; The air inlet of axial flow blower 4 and air pipe 5 are rigidly connected; The air outlet of axial flow blower 4 is connected to the motor air inlet place of the non-shaft stretching end of electric machine stand 1.Stator 2 inner dashing have 90 small sircle holes of a row, and internal rotor is provided with 3 row's big holes and forms the axial ventilation road; Electric machine stand 1 shaft extension end is provided with a plurality of square exhaust vents.
See also shown in Figure 2ly, in the preferred embodiment of the utility model, cooling air is blown in the air pipe 5 through air-blast device.Because the existence of axial flow blower 4 has increased the pressure reduction at air pipe 5 two ends, also increased the pressure differential between the motor inlet and outlet simultaneously.Strengthened the turbulent motion of cooling air so greatly, made radiation effect of motor better at motor internal.
