排气式电子风表在提高旅客列车制动机试验减压速度中的应用

Application of the Exhaust Type Electronic Wind Meter in Improving the Pressure Reducing Speed in the Test for Passenger Train Brakes

分析了旅客列车制动机试验尾车制动管减压速度低的原因,阐述了排气式电子风表提高尾车减压速度的工作原理,提出了使用一个高频开关电磁阀完成不同列车编组时各项制动试验所要求的减压速度的方法。

The causes to low pressure reducing speed in the brake pipe on the end car during the test for passenger train brakes are analyzed.The working principle of improving the pressure reducing speed in the end car with the exhaust type electronic wind meter is expounded.The method to acquire the pressure reducing speeds required by various braking tests with different compositions of trains with the use of one high frequency switch electromagnetic valve is put forward.
