汽车测试FCPV使用PLC和ADC联合空气泄漏检测

文摘

大多数车辆参与事故现在一天大型车辆如卡车、公共汽车和拖车。他们从小型汽车制动系统是完全不同的。他们有空气罐制动系统,因此所需的空气量是巨大的。空气制动系统使用空气作为一种传输服务的司机控制制动器的压力。压缩空气有水不能被压缩。更多的水的坦克的压缩空气量就越少。只要脚刹车,使用大量的空气。如果气压不建立快速的压力可能会下降到低系统中如果存在泄漏影响整个制动系统的车辆的效率。泄漏可以被定义为一个裂缝,孔或孔隙度联合必须排除在系统之外。泄漏测试程序通常是保证设备的完整性和质量控制步骤应该最好是一次性的非破坏性测试,不影响环境和运营商。 The three basic functions of leak testing are leakage detection and its location, measurement of leak rate.One of the test presently used in industry is soap solution bubble test. The pressurized unit to be tested is sprayed with a soap solution and the operator is able to see the bubbles formed by gas escaping from where the leak is, the more the bubbles the larger is the leakage .If the part is not simple and easily accessible it is difficult for operator to perform above mentioned test, also the test is time consuming, affecting the efficiency, accuracy and productivity of system. To overcome the disadvantages of the above mentioned system we are implementing pressure decay test using PLC which would determine air leakage between ADC(Air Dryer cartridge) and FCPV(Four Circuit Protection Valve) joint to improve the braking efficiency of vehicle system.
