消防水泵在消防给水系统中的作用相当于人的心脏，是所有水系统的动力所在，故消防水泵启动和控制的相关知识一定要认真掌握，做到灵活运用。

The role of fire pump in the fire water supply system is equivalent to the heart of people and is the power of all water systems. Therefore, the relevant knowledge of fire pump startup and control must be carefully mastered and flexibly used.

为什么启泵信号规定为压力和流量开关？

Why is the pump start signal specified as a pressure and flow switch?

国际上发达的启泵信号是压力和流量开关，其原因是可靠性高，水流指示器可靠性稍差，误动作率稍高，我国在工程中也经常采用高位消防水箱的水位信号，但因高位消防水箱的水位信号有滞后现象，目前已在工程中很少采用，但该信号可以作为报警信号。

The pump starting signal in developed countries is the pressure and flow switch. The reason is that the reliability is high, the reliability of the water flow indicator is slightly poor, and the misoperation rate is slightly high. China also often uses the water level signal of the high-level fire water tank in projects. However, due to the lag of the water level signal of the high-level fire water tank, it has been rarely used in projects at present, but this signal can be used as an alarm signal.

为此规范规定采用压力开关和流量开关作为水泵启泵信号，压力开关一般可采用电接点压力表、压力传感器等。压力开关通常设置在消防水泵房的主干管道上或报警阀上，流量开关通常设置在高位消防水箱出水管上。

For this reason, the specification stipulates that the pressure switch and flow switch are used as the pump start signal, and the pressure switch can generally use the electric contact pressure gauge, pressure sensor, etc. The pressure switch is usually set on the main pipeline or alarm valve of the fire pump room, and the flow switch is usually set on the outlet pipe of the high-level fire water tank.

为什么要设置机械应急启泵装置？

Why is the mechanical emergency pump starting device set?

①压力开关、流量开关等弱电信号和硬拉线是通过继电器来自动启动消防水泵的，如果弱电信号因故障或继电器等故障不能自动或手动启消防水泵时，应依靠消防水泵房设置的机械应急启动装置启动消防水泵。

① Weak current signals such as pressure switch and flow switch and hard pull wire automatically start the fire pump through relay. If the fire pump cannot be started automatically or manually due to weak current signal failure or relay failure, the fire pump shall be started by relying on the mechanical emergency starting device set in the fire pump room.

②当消防水泵控制柜内的控制线路发生故障而不能使消防水泵自动启动时，若立即进行排除线路故障的修理会受到人员素质、时间上的限制，所以在消防发生的情况下是不可能进行的。

② When the control circuit in the fire pump control cabinet fails to start the fire pump automatically, the immediate repair of the circuit failure will be limited by the quality of personnel and time, so it is impossible to carry out the repair in case of fire.

③基于以上原因规范规定，消防水泵只要在供电正常的条件下，无论控制性线路如何，都能强制启动，以保证火灾扑救的及时性。

③ Based on the above reasons, the specification stipulates that the fire pump can be forcibly started as long as the power supply is normal, regardless of the control line, so as to ensure the timeliness of fire fighting.

机械应急启动不超过5.0min，都包含哪些时间？

The mechanical emergency start shall not exceed 5.0min. What time does it include?

该机械应急启动装置在操作时必须由被授权的人员来进行，且此时从报警到消防水泵的正常运转的时间不应大于5min，这个时间可包含了管理人员从控制室消防水泵房的时间，以及水泵从启动到正常工作的时间。

The mechanical emergency starting device must be operated by authorized personnel, and the time from alarm to normal operation of the fire pump shall not be more than 5min. This time can include the time from the control room to the fire pump room and the time from start to normal operation of the pump.

川消小编提醒，当消防给水分区供水采用转输消防水泵时，转输泵宜在消防水泵启动后再启动；当消防给水分区供水采用串联消防水泵时，上区消防水泵宜在下区消防水泵启动后再启动。

Chuanxiao Xiaobian reminded that when the transfer fire pump is used for water supply in the fire water supply zone, the transfer pump should be started after the fire pump is started; When series fire pumps are used for water supply of fire water supply zones, the fire pumps in the upper zone should be started after the fire pumps in the lower zone are started.

消防水泵控制柜设置在专用消防水泵控制室时，其防护等级不应低于IP30；与消防水泵设置在同一空间时，其防护等级不应低于IP55。

When the fire pump control cabinet is set in the special fire pump control room, its protection grade shall not be lower than IP30; When it is set in the same space as the fire pump, its protection grade shall not be lower than IP55.
