The embodiment of the invention relates to an air supply system for a rail train. The air supply system comprises an inflation and deflation device, at least two sets of air springs and an inflation and deflation control unit, the inflating and deflating device comprises a high-low pressure integrated gas tank, an internal and external circulating valve and a first air compressor; if the inflation and deflation control unit detects that the air spring is compressed, a gas tank high-pressure area of the high-low pressure integrated gas tank is communicated with a gas path of the air spring, so that gas in the gas tank high-pressure area is inflated into the air spring; if the inflation and deflation control unit detects that the air spring is continuously pulled up, a gas tank low-pressure area of the high-low pressure integrated gas tank communicates with a gas path of the air spring, and gas in the air spring is released to the gas tank low-pressure area; an internal and external circulation valve and a first air compressor are sequentially arranged between the air tank low-pressure area and the air tank high-pressure area, and the air tank is controlled to be switched to a high-low-pressure area communication state or an atmosphere communication state through the internal and external circulation valve.
本发明实施例涉及一种轨道列车供气系统,该系统包括充放气装置、至少两套空气弹簧、充放气控制单元;充放气装置包括高低压一体式气罐、内外循环阀和第一空压机;若充放气控制单元检测到空气弹簧被压缩,将高低压一体式气罐的气罐高压区与空气弹簧的气路连通,使气罐高压区的气体充入空气弹簧;若充放气控制单元检测到空气弹簧持续拉升,将高低压一体式气罐的气罐低压区与空气弹簧的气路连通,使空气弹簧内的气体释放至气罐低压区;气罐低压区与气罐高压区之间依次设有内外循环阀和第一空压机,通过内外循环阀控制切换至高低压区连通状态或大气连通状态。
