由公安部天津消防科学研究所与浙江乐清机械厂共同研制的PF4型水轮式高倍数泡沫发生器于1984年12月1日至3日在浙江省消防器材公司主持下通过了技术鉴定。 高倍数泡沫灭火是一种较新的灭火技术。适用于控制和熄灭A类和B类火灾。特别是对有限空间大面积火灾的扑救更为有效,如车间、油库、大型仓库、隧道、飞机库、地下建筑、船舶等处火灾。对液化气体火灾的控制亦很有效。还可作为大型建筑物和地下铁道火灾的防火隔断使用。
The PF4-type hydrofoil high multiple foam generator jointly developed by Tianjin Fire Science Institute of Ministry of Public Security and Yueqing Machinery Factory of Zhejiang passed the technical appraisal under the auspices of Zhejiang Provincial Fire Equipment Company from December 1 to 3, High-fold foam fire extinguishing is a relatively new fire-fighting technology. Suitable for controlling and extinguishing Category A and Category B fires. Especially for a large area of limited space fire fighting more effective, such as workshops, oil depots, large warehouses, tunnels, hangars, underground buildings, ships and other fires. Control of liquefied gas fire is also very effective. It is also used as a fire barrier for large buildings and subway fires.
