Abstract
The utility model provides a traction motor cooling fan adapted to a low-temperature environment. The traction motor cooling fan adapted to the low-temperature environment comprises an aluminum alloy machine shell assembly, a motor, a carbon steel impeller and an air inlet. The motor is fixed to the aluminum alloy machine shell assembly and located at one side of the aluminum alloy machine shell assembly. The motor is connected with the carbon steel impeller. The carbon steel impeller is located in the machine shell assembly. The air inlet is fixed in the machine shell assembly and located at the other side opposite to the motor. The traction motor cooling fan adapted to the low-temperature environment has the advantages that the purposes that under the low-temperature environment, an air feeder of a traction motor of a motor train unit can be continuously cooled and the rated power of the air feeder satisfies the actual requirements of the air feeder are achieved and the air feeder can be operated safely and reliably for a long time.
Description
Technical field
The utility model relates to EMU traction electric machine cooling blower, particularly a kind of traction electric machine cooling blower that adapts to long-term use under ℃ environment of low temperature-45.
Background technique
EMU is used the cooling blower of traction electric machine at present, and its minimum serviceability temperature is-25 ℃.But work as high speed motor car at extremely frigid zones, ℃ lower long-time running in low temperature-45, the part component can be because holding the cold operation condition of can't stand, the faults such as gross distortion, welding seam breaking occur, even can cause the gas fan actual power to surpass rated power, damage motor, shorten motor working life, affect rail motor set and reach safely reliable operation.
Summary of the invention
In order to overcome the above problems, the utility model provides a kind of can adapt to low temperature environment, meet the traction electric machine cooling blower that rail motor set can normal operation under low temperature-45 ℃.
A kind of traction electric machine cooling blower that adapts to low temperature environment described in the utility model comprises: aluminum alloy casing composition, motor, carbon steel impeller, intake grill, wherein motor is fixed on the side that the casing composition was gone up and be positioned to aluminum alloy casing composition, motor is connected with the carbon steel impeller, the carbon steel impeller is positioned at casing and forms, intake grill is fixed on casing and forms above, is positioned at the opposite side opposite with motor.
A kind of traction electric machine cooling blower that adapts to low temperature environment of the utility model, can meet gas fan under low temperature environment, be continuously rail motor set traction electric machine gas fan and cool, gas fan rated power meets the gas fan actual requirement, and can meet gas fan long-term safety reliable operation.
In order to reach better effect, a kind of traction electric machine cooling blower that adapts to low temperature environment described in the utility model can also adopt following measures:
1, the utility model also comprises a guard, is fixed on casing and forms above, and it is positioned at the intake grill outside.Its role is to dust shielding outside blower fan, make the interior air-flow of blower fan purer, avoid damage equipment.
2, casing described in the utility model forms the top that is positioned at motor one side the motor pad is set, and motor is fixed on casing by this motor pad and forms.
3, on motor described in the utility model, air plug also is set, is connected with motor by cable.
The accompanying drawing explanation
Fig. 1 is a kind of structural representation that adapts to the traction electric machine cooling blower of low temperature environment described in the utility model.

Embodiment
In conjunction with Fig. 1, a kind of traction electric machine cooling blower that adapts to low temperature environment described in the utility model is elaborated.
A kind of traction electric machine cooling blower that adapts to low temperature environment described in the utility model comprises:
A casing forms 3;
Be arranged on the motor 2 that casing forms 3 one sides, motor 2 is lifted on casing by motor backing plate 1 and forms on 3;
The air plug 6 that motor 2 is connected with power supply and connect the cable 5 of air plug 6 and motor;
Being located at casing forms in 3 and is arranged on the impeller 8 on motor 2 output shafts;
Be fixed on intake grill 9 and the guard that casing forms on 3 and form 10, its two by intake grill fixed block 7, be fixed on casing and form on 3.
Dunnage 4 is fixed on casing and forms 3 top, at the bottom of whole traction electric machine cooling blower is fixed on the EMU car by this dunnage 4.
In above each component, casing composition 3, intake grill 9 are selected low temperature resistant aluminum alloy material; Impeller forms 8 and adopts low temperature resistant New Type of Carbon Steel material; Motor backing plate 1, guard form 10 the low temperature resistant stainless steel material of intake grill fixed block 7 employing high-quality; Low temperature resistant product is chosen or customized to air plug 6, cable 5, motor 2.Thereby make a kind of traction electric machine cooling blower that adapts to low temperature environment described in the utility model can adapt to the traction electric machine cooling blower of low temperature environment, meeting rail motor set can normally operation under low temperature-45 ℃.
