The invention relates to the technical field of rail transit vehicles, in particular to an intelligent air supply unit for a rail transit vehicle. The intelligent air supply unit for the rail transit vehicle comprises an air compressor unit, air treatment equipment and a controller. The air compressor unit comprises an air compressor, one side of the air compressor is an air inlet channel, the other side of the air compressor is an air supply channel, and the air supply channel communicates with the air treatment equipment and is further connected with a first branch used for exhausting air; a lubricating oil temperature sensor is arranged in the air compressor, and the lubricating oil temperature sensor is used for monitoring the temperature of lubricating oil in the air compressor and transmitting a temperature signal to the controller; according to the air supply unit, a humidity sensor does not need to be arranged at the air inlet of the air compressor, whether the emulsification risk exists or not is judged by directly monitoring the temperature of lubricating oil, and the flow of the air inlet is not affected. When the lubricating oil of the air compressor is considered to have the emulsification risk, the anti-emulsification mode can be started, air is exhausted to the outside through the air compressor, the high-temperature working time is prolonged, and the emulsification risk of the lubricating oil is reduced.
本发明涉及轨道交通车辆技术领域,尤其是涉及一种轨道交通车辆用智能供风单元。轨道交通车辆用智能供风单元包括空压机组、空气处理设备和控制器;空压机组包括空压机,空压机的一侧为进气通路,另一侧为供风通路,供风通路与空气处理设备连通,且供风通路还连接有用于排风的第一支路;空压机内设置有润滑油温度传感器,润滑油温度传感器用于监测空压机内润滑油温度,并将温度信号传输至控制器;该供风单元不需要在空压机进气口设置湿度传感器,而是通过直接监控润滑油温度的方式,判断是否存在乳化风险,不影响进气口流量。在认为空压机润滑油存在乳化风险时,可启动防乳化模式,通过空压机向外界排风,延长其高温工作时间,降低润滑油乳化风险。
