Water supply test and application analysis of ultra-high-pressure fire pump in super high-rise buildings

Abstract

Abstract: Fire water supply is the key to firefighting of super highrise buildings. The practical application of an ultra-high-pressure fire pump in a super high- rise building was tested to obtain key technical parameters of pressure and flow. The test results showed that the water supply height is 303 m, the maximum pressure of the water pump is 7.5 MPa, the water supply flow rate is 26.9 L/s, the maximum flow rate is 44.4 L/s. The theoretical water supply height is over 600 m, which meets the actual firefighting needs.The system has the advantages of high pressure, large flow and high reliability. It can respond to the fire water supply problem of super high-rise buildings effectively

Key words: super high-rise building, fire water supply, pressure
