随着我国石油开采业及其加工业的迅速发展,与易燃、可燃液体打交道的场所与日俱增,其中尤以易燃、可燃液体贮罐为主。至此,相伴随的低倍数泡沫灭火系统的设计与应用也就更加广泛。虽然目前世界上所采用的泡沫比例混合流程有多种,然而在我国多采用环泵比例混合流程,且其结构形式不尽相同,其中不少地方采用自灌泵式流程。 With the rapid development of petroleum exploitation industry and its processing industry in our country, the places dealing with flammable and combustible liquids are increasing day by day, especially the flammable and flammable liquid storage tanks. At this point, the design and application of the low multiple foam fire extinguishing system is also more extensive. Although there are many kinds of foam proportion mixing processes in the world at present, the proportion of ring pumps in our country is mostly used, and the structure forms are not the same. Many of them use self-filling pump processes.
