Braking system testing equipment and method

Abstract

The invention provides a braking system testing equipment and method. The braking system testing equipment comprises a general air pipe connection pipeline, a train pipe connection pipeline, an air source pipeline and a control module, wherein a connector of the general air pipe connection pipeline is used for connecting a general air pipe of a vehicle to be detected; the pipeline is provided with a general air pipe pressure transmitter; a connector of the train pipe connection pipeline is used for connecting a train pipe of the vehicle to be detected and the pipeline is provided with a train pipe pressure transmitter and is further provided with a deflating valve; a connector of the air source pipeline is used for connecting an air source; the air source pipeline is communicated with the general air pipe connection pipeline by a first pressure adjusting valve and the general air pipe and is communicated with the train pipe pressure transmitter by a second pressure adjusting valve and an inflating valve; the control module is used for controlling the opening and the closing of the first pressure adjusting valve, the second pressure adjusting valve, the inflating valve and the deflating valve and obtaining pressure values of the general air pipe pressure transmitter and the train pipe pressure transmitter to be used as testing results. The braking system testing equipment and method can be used for carrying out an efficient, simple and convenient, and comprehensive test on a braking system and the reliability of operating the vehicle braking system is guaranteed.

Description

technical field [0001] The invention relates to a pneumatic equipment testing technology, in particular to a braking system testing equipment and method. Background technique [0002] The brake system is a necessary part of a railway passenger car. Its braking principle is to use the change of gas pressure to drive the brake parts to act when the pressure in the air cylinder is released, and to brake the axle or wheel set, and the pressure in the air cylinder rises. When driving the brake part to return, release the brake. The existing braking system mainly includes a brake air cylinder, an auxiliary air cylinder and an additional air cylinder, which are respectively connected with the main air pipe and the train pipe arranged on the vehicle, and control the action of the valve body in the pipeline to realize the internal pressure of the air cylinder. rise and release. [0003] In order to ensure the reliability of the operation of the braking system, it is necessary to de...
