摘要
汽车翻转阀作为汽车燃油系统中重要的一种安全保护阀,其检测项目多且精度要求高,主要是汽车翻转阀在不同姿态角度转动、不同工作压力或真空度下空气排出或吸进的体积流量。设计一种汽车翻转阀气密检测系统,以S7-200 Smart PLC为控制核心,自动完成汽车翻转阀装夹、封堵、气密检测等,可满足汽车翻转阀气密检测精度要求,极大地提高了检测效率。
As an important safety protective valve in vehicle fuel system, roll-over valve has a lot of testing items, and most of them require high accuracy. Those main items test exhaust or inspiratory air flow rate under various angle attitude and positive-negative pressure. An air-sealing testing system was designed for roll-over valve based on S7-200 smart PLC, by which clamping, plugging and air-sealing testing etc could be achieved. Practice has proved that it can meet testing requirements and improve testing efficiency.
