    Abstract：An improved control schematic diagram of the water pump is proposed for the design of the spray system of an actual underground garage. When a fire alarm occurs in the mechanical garage，three pumps operate in the state of two in use and one on standby. When the fire alarm occurs in an ordinary garage，they can be automatically converted to the operating state of one in use and one on standby.

    摘 要：针对某实际地下车库喷淋系统设计，提出一种改进后的水泵控制原理图：当机械车库发生火灾报警时3台水泵按照两用一备状态运行；当火灾报警为普通车库时能够自动转换为一用一备运行状态。
