Design and Performance Test of a Novel Type of Gas Path Brake Control System Testing Instrument

Abstract

This paper presents the structure design and the performance testing method of a novel type of gas braking control system. Based on PDSOFT 3D design method double gas detection instrument control system has been carefully designed, effectively using the space of the case body. Using a direct acting overflow pressure reducing control technology, effectively through gas level decompression pressure were quickly and accurately is reduced to 0.7Mpa and 0.45Mpa, according to the tightness test results show, the tester can keep the pressure stability of the error is less than 0.1%. With quick joints of interlocking sealing design technology based on, settle the problem of connecting and sealing between the traction chassis brake system pneumatic hose and gas path instrument brake control pipeline, detection of gas pipeline. In the design of DC regulated power supply, the innovation to the DC voltage stabilizing circuit modular design, can effectively avoid the input voltage fluctuation on the influence of the load end, to ensure the stable operation of the independent power supply module tester. The tester can be easily used to test their performance general traction air braking system chassis in the stationary state, and can be directly used digital display reading way test data will be output directly, save the test time, improve the test efficiency.
