Title: TRACTION FAN COOLING AIR VOLUME ADJUSTING METHOD AND DEVICE
Abstract:
Provided are a traction fan cooling air volume adjusting method and a device. The device comprises: an altitude acquisition module (1), which is used for obtaining an altitude where a locomotive locates, and sending the altitude information to a control module (2); the control module (2), which is used for determining, according to the altitude, air density corresponding to the altitude in a preset altitude and air density database, for calculating a reference rotation speed of the traction fan according to the air density, and sending a control signal to a traction control module (3); and the traction control module (3), which is used for adjusting an operating speed of the traction fan according to the control signal. The device can intelligently, rapidly and automatically adjust the rotation speed of the traction fan according to the altitude, and fully ensure the sufficient cooling fresh air for the traction motor, achieving a better air cooling effect and realizing the purpose of automatic altitude adaptation of the traction fan.
