摘　　要：火灾初期消防给水稳压设备的工作过程大致分为两个阶段。第一个阶段是气压罐里储存的有压水暴发式喷发的过程;第二个阶段是稳压泵持续独立运行的过程。通过对这两个过程的研究发现启用第一只消防水枪后,消防给水稳压设备的出流情况不稳定,相较高位消防水箱出水灭火而言其灭火效果不佳。The working process of fire protection water supply and pressure stabilizing equipment in the early stage of fire is divided into two stages.The first stage is an explosive eruption of pressurized water stored in a pressurized tank.The second stage is the process of continuous and independent operation of the pressure stabilizing pump.By studying these two processes,it was found that the water discharge situation of fire protection water supply and pressure stabilizing equipment is not stable after the first hydrant is used.And its fire extinguishing effect was not as good as the high-place fire protection water tank’s.
