摘要
消防供水是超高层建筑火灾扑救的关键因素之一,通过试验测试超高压消防泵在超高层建筑的实际应用,获得压力、流量等关键技术参数。试验结果表明,供水高度303 m,水泵最高压力7.5 MPa,供水流量26.9 L/s,最大流量达到44.4 L/s,理论供水高度可超600 m,满足实际灭火需求。该系统具有压力高、流量大、可靠性高等优点,能有效解决超高层建筑消防供水难题。
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.
