The role of the pressure gauge on the train
The pressure gauge shows the air pressure of the train brake hose. The air pressure for safe operation is 600KPa units, which is kPa
Dude, you're a railroad, aren't you?!Good business knowledge ~!
There are two pressure gauges on the train locomotive, called "balanced air cylinder, double needle pressure gauge", for monitoring the pressure of the equalizing cylinderThe emergency brake beside the carriage also has a pressure gauge in the car. Mainly to look at the pressure of the car air cylinder, referred to as wind pressure.Additional knowledge: how to use the emergency brake valve?When using the emergency brake valve of the vehicle, it is not necessary to break the seal first, and immediately pull the valve handle to the fully open position until it is fully opened so as not to stop or close. In case of a spring handle, you must not let go before the train stops completely. In the long slope, we must look at the pressure gauge, such as gauge is determined by pressure drop 100Kpa, shall not use the emergency brake valve (except when the angle cock is closed).
