摘要
大规模泡沫消防工程对泡沫混合液的混合比的精确性提出了更高的要求,设计一种采用注入式泡沫比例混和装置的灭火系统,该系统用交流变频调速和PLC控制技术来调节泡沫输出量,得到了精确的泡沫混合比,使泡沫灭火达到一个更有效的水平。
In the large-scale foam extinguishing system, a higher accuracy of mixture proportion is very important.So the foam extinguishing system with injection model is designed, in which foam output is adjusted by using variable frequency driv-ing and PLC control technology.As a result, exact mixing ratio is obtained and foam extinguish achieve a more effective level.
