干粉滅火系統(tǒng),，由干粉供應源通過輸送管道連接到固定的噴嘴上，通過噴嘴噴放干粉的滅火系統(tǒng),。下面
川消小編為您講解下干粉滅火系統(tǒng)組件設置以及要求事項吧,。
The powder extinguishing system is a fire extinguishing system that connects a dry powder supply source to a fixed nozzle through a conveying pipeline, and sprays dry powder through the nozzle. Below, the editor of Chuanxiao will explain to you the component settings and safety requirements of the dry powder fire extinguishing system.
