【摘要】 介绍研制用于气体保护焊的供气系统。该系统由气路系统、混配系统、检测传感系统、电气控制系统、机械结构系统等分系统组成,实现Ar和CO2按一定比例混配,保证控制较高的配比精度,能实现CO2比例的实时反馈,并由计算机进行自动控制,实现压力和湿度的实时监控显示,能实现配比和压力超标的电声光报警。更多还原

【Abstract】 This paper introduces the gas supply system in the gas-shielded arc weld .The system is composed of gas-route system,mixture-gas system, detection system, electric control system, mecha-nism system, and etc. It can mix Ar and CO2 in proportion andreach high precision. The system complete CO2 proportion reactionreal-timely and control by computer. At the same time, the systemcan realize the real-time monitoring control for pressure and humid-ity, and can alarm by the electricity, sound or light once the com-position or the pressure exceed the limit.更多还原
