设备主要组成及功能；
1 控制器；是本系统的控制机构，其动作直接受执行机构控制。是二氧化碳，氩气混合配比的关键部件。
2 分析仪；是本系统的检测机构，显示配比气中的二氧化碳百分比含量，并把二氧化碳百分比含量转换成电信号。
3 智能显示调节仪；是本系统的控制器，把二氧化碳分析仪的电流信号与设定值比较计算，计算结果转换成执行器需要的4电信号，调节二氧化碳的浓度。智能显示调节仪设定了混合气浓度上下限声光报警输出.
6 混合罐；把二氧化碳，氩气混合配比。
7 混合气流量计；把混合后的气体流量显示出来。（获取正确的读数，需要用混合气密度和压力修正）
Carbon dioxide Argon mixed gas distribution automation
The valve means is adjusted by carbon dioxide, argon gas was added to obtain a stable mixed gas of argon and carbon dioxide having a certain proportion. With automatic adjustment.
Main Specifications;
1, the raw material gas;
Carbon dioxide gas pressure ≤0.7-0.9Mpa
Argon pressure ≤0.7-0.9Mpa
2, the working pressure ≤0.7-0.9MPa
3, the amount of carbon dioxide mixed gas containing 10-30%
Mixture pressure ≤0.4-0.5MPa
4, installed power 0.2KW
5, power supply 220V, 50HZ
The main equipment components and functions;
1 Controller; the control mechanism of the system, which is directly affected by the operation of the actuator control. Carbon dioxide is a key component, the mixing ratio of argon.
2 analyzer; a detection mechanism of the system, showing the percentage of carbon dioxide content in the gas ratio, and the percentage content of carbon dioxide is converted into an electrical signal.
3 smart display regulator; is the system controller, the carbon dioxide analyzer current signal with the set value comparison calculation, the calculation result is converted into an electrical signal 4 actuators needed to adjust the concentration of carbon dioxide. Intelligent display regulator set a limit on the concentration of the mixture of sound and light alarm output.
6 mixing tank; carbon dioxide, argon mixing ratio.
7 mixed gas flowmeter; flow rate of the gas mixture is displayed. (Get the correct readings need to be amended with a mixed gas density and pressure) |
