Title
(EN) Fixed type class B foam extinguishing device and control method thereof
(ZH) 一种固定式B类泡沫灭火装置及灭火装置的控制方法
Abstract
(EN)
The invention relates to a fixed type class B foam extinguishing device and a control method thereof. Through the combination of a foam pump system, a water pump system and an air compressor system, class B foam, water and compressed air are mixed, foam formed at a spraying outlet is full in foaming, wild fire is not liable to be formed, and the foam can be used for extinguishment of oil fire andother liquid fire disasters. The water pump system, the air compressor system and the foam pump system are driven by individual power. Closed-loop control is conducted on a water pump, an air compressor and a foam pump through a PLC, the foam proportion can be adjusted in a large range, meanwhile the water flow can be adjusted in a large range, and thus the adjusting range of the extinguishing device becomes larger and can be adjusted freely between 20%-100% of the maximum flow. Through the fixed type class B foam extinguishing device and the control method thereof, the firefighting problem oflarge liquid fire disasters is solved.

本发明涉及一种固定式B类泡沫灭火装置及灭火装置的控制方法,通过泡沫泵系统、水泵系统、空压机系统的组合,实现B类泡沫、水、压缩空气的混合,在喷淋出口形成的泡沫发泡充分,不容易形成流火,可用于油类等液体火灾的灭火。水泵系统、空压机系统及泡沫泵系统采用单独的动力驱动,通过PLC控制器对水泵、空压机及泡沫泵闭环控制,不但可以对泡沫比例进行大范围调节,同时可以大范围调节水流量;使得灭火装置的调节范围变大,可在最大流量的20%‑100%之间任意调节。固定式压缩空气B类泡沫灭火装置及灭火装置的控制方法解决了大型的液体火灾的消防问题。
