摘要
设计了一种标准气体自动配气装置。该装置选用FX3U PLC作为主要控制核心,采用比例混合法;通过对气体质量流量计开度的精确控制,实现了标准气体的自动配置;通过增压的方式实现了高压气瓶灌装。该装置具有自动化程度高、精度高等优点,并在生产中得到了应用。
Designed a kind of standard gas automatic distribution device. This device uses FX3U PLC as the main control core, adopts the proportional mixing method. Through the accurate control of the gas mass flowmeter opening, the automatic configuration of standard gas is realized. The filling of high-pressure gas bottle is realized by means of supercharging. The device has the advantages of high automation degree and high precision, and has been applied in the production.
