Fire-fighting foam is an aggregate of air-filled bubbles formed from aqueous solutions and has a lower density than that of flammable liquids. It is principally used to form a cohesive floating blanket over flammable and combustible liquids and prevents or extinguishes fire by excluding the air and cooling the fuel. It also prevents from reignition by suppressing formation of flammable vapors. Therefore, Fire-fighting foam can be used as a fire prevention, control, or exposure protection for flammable liquid fire hazards.

消防泡沫是一种填充空气的泡沫水溶液集合体,其密度比易燃性液体低,并可粘著、覆盖於易燃性与可燃性液体表面而达到隔离空气、冷却燃料及防止燃料持续蒸发引燃等功用,所以消防泡沫常使用在易燃性危险液体之预防火灾、制压火势及防阻延烧上。

When pump starts, the lower impeller lifts the solution up step by step. And the extreme centrifugal force from the enlarged higher impeller stops the solution as it entering the higher impellr. At the same time, the full solution in the chamber stops the air mixed with the solution in the chamber to go down. This way masterly eliminates both big problems of vertical sealless pump, overflow at high pressure and bubbles at big flow.

塑宝SV泵剖面结构SV Super Series Analytical cross section SV泵剖面结构泵开始运转时,底部叶轮将液体逐步上推,待液体进入上部叶轮时,即受加大之背叶的强大阻力而无法上升,但上部叶轮所卷入液体中的空气,却受阻於水室中贮满的液体而无法下降,如此巧妙地排除了立式无轴封泵高压时溢流,或大流量时吸入空气的两大难题。
