| 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。

Design of Air sealing Testing System for Roll over Valve Based on S7 200 Smart PLC |
| |
| Abstract: | 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 . |
