消防泵是指符合标准的消防泵性能要求和试验方法GB普通清水泵或专用消防泵6245。在给排水消防设计中，合理设计消防泵非常重要，消防泵的可靠启动泵也应得到有效保证，其重要性不言而喻。今天川消小编带你了解消防泵的启泵的六大控制原理。

Fire pump refers to the standard fire pump performance requirements and test methods GB ordinary clean water pump or special fire pump 6245. In the water supply and drainage fire protection design, reasonable design of fire pump is very important, and the reliable starting pump of fire pump should also be effectively guaranteed, which is self-evident. Today, Chuanxiao Xiaobian will introduce you to the six control principles of fire pump startup.

高消防水箱出水管流量开关启动泵

High fire water tank outlet pipe flow switch starts pump

流量开关又称水流开关、流量传感器和水流动作阀，是一种传感控制器，利用各种原理测量管道中介质的流量，并及时传输给后端设备，用于开关通信信号。当流量高于或低于设定点时，流量开关触发报警信号，系统可以在获得信号后做出相应的指示动作。

Flow switch, also known as water flow switch, flow sensor, and water flow action valve, is a sensing controller that uses various principles to measure the flow rate of the medium in the pipeline and transmit it to the back-end equipment in a timely manner for switching communication signals. When the flow rate is above or below the set point, the flow switch triggers an alarm signal, and the system can make corresponding indication actions after obtaining the signal.

消防泵出水管压力开关启动泵

Pressure switch of fire pump outlet pipe starts the pump

压力开关是指通过特殊的CPU模块化信号处理技术，实现介质压力的检测、显示、报警和控制信号输出，采用高精度、高稳定性的压力传感器和传输线路。

Pressure switch refers to the use of special CPU modular signal processing technology to achieve the detection, display, alarm, and control signal output of medium pressure, using high-precision and high stability pressure sensors and transmission lines.

在水消防系统中，低压开关一般设置在消防泵出水管上。当流量开关失效时，水消防系统继续依靠水箱和稳压泵提供水量和水压灭火，稳压泵不及时补水会导致系统压力下降。或仅依靠消防水箱静水压力灭火，水箱水位下降，消防泵出水压力开关感应压力下降，压力开关动作。当流量开关失效时，无论消防水箱是否设置稳压泵，供水过程中的压力都会下降，压力开关的设置就是基于这一基本原理。

In the water firefighting system, the low-pressure switch is generally set on the outlet pipe of the fire pump. When the flow switch fails, the water firefighting system continues to rely on the water tank and pressure stabilizing pump to provide water and water pressure for firefighting. Failure to replenish water by the pressure stabilizing pump in a timely manner can lead to a decrease in system pressure. Or only rely on the hydrostatic pressure of the fire water tank to extinguish the fire, the water level of the water tank drops, the fire pump outlet pressure switch senses the pressure drop, and the pressure switch acts. When the flow switch fails, regardless of whether the fire water tank is equipped with a pressure stabilizing pump, the pressure during the water supply process will decrease. The setting of the pressure switch is based on this basic principle.

报警阀压力开关启动泵

Alarm valve pressure switch starts pump

湿式报警阀组的压力开关是安装在延迟器与水力报警管道之间的压力水流探测开关。报警阀打开后，报警管道充水，流向水力报警铃。压力开关在接收水压时接通电触点，并给出电接点信号。报警阀压力开关的结构和要求是：当系统中出现一个或多个喷嘴流量时，压力开关动作自动启动喷淋泵，并发出火灾报警信号。当流量停止时，电触点断开。

The pressure switch of the wet alarm valve group is a pressure water flow detection switch installed between the delay device and the hydraulic alarm pipeline. After the alarm valve is opened, the alarm pipeline is filled with water and flows to the hydraulic alarm bell. The pressure switch connects the electrical contact when receiving water pressure and provides an electrical contact signal. The structure and requirements of the alarm valve pressure switch are: when one or more nozzle flows in the system, the pressure switch automatically starts the spray pump and sends a fire alarm signal. When the flow stops, the electrical contacts open.

手动启泵

Manually start the pump

手动启泵功能应设置在消防控制室或消防泵房。为保证消防控制室启动泵的可靠性，采用硬拉线直接启动消防泵，可尽量减少干扰和风险。在情况下，由于联动控制存在失效的可能性，如软件受病毒侵害等危险，导致弱电信号总线无法移动。由此可见，手动直接启泵是消防启泵必不可少的防线。消防控制室的手动控制盘设置在消防控制室的消防联动控制器上。

Manual pump starting function shall be set in the fire control room or fire pump room. In order to ensure the reliability of starting the pump in the fire control room, the hard cable is used to directly start the fire pump to minimize interference and risk. In this case, due to the possibility of failure in the linkage control, such as the risk of software being infected by viruses, the weak signal bus cannot be moved. From this, it can be seen that manual direct pump starting is an essential line of defense for fire pump starting. The manual control panel of the fire control room is set on the fire linkage controller of the fire control room.

自动启泵

Automatic pump start

消防设备需要自动火灾报警系统的联动控制，其联动触发信号应采用两个独立的报警触发装置报警信号的“和”逻辑组合。联动触发信号包括温度（烟雾）火灾探测器信号、手动火灾报警按钮信号、压力（流量）开关动作信号、消火栓按钮动作信号灯。联锁控制模式和消防联动控制器（联动控制模式）均可实现消防泵的自动启动。

The fire protection equipment requires the linkage control of the automatic fire alarm system, and its linkage trigger signal should adopt the "and" logic combination of two independent alarm trigger devices' alarm signals. The linkage trigger signals include temperature (smoke) fire detector signals, manual fire alarm button signals, pressure (flow) switch action signals, and fire hydrant button action signal lights. Interlocking control mode and fire linkage controller (linkage control mode) can realize automatic startup of fire pump.

机械应急启动泵

Mechanical emergency start pump

弱电信号和硬拉线，如压力开关和流量开关，都是通过继电器自动启动消防泵的。消防系统中的应急机械启动功能是通过手动关闭消防泵启动的，是指信号线或消防泵控制箱的控制线故障，通过消防泵控制箱门上的机械应急启动装置，直接手动关闭消防泵的主接触器启动消防泵。只要消防泵在正常供电条件下，无论控制线路如何，都可以强制启动，以确保消防的及时性。

Weak current signal and hard pull wire, such as pressure switch and flow switch, automatically start fire pump through relay. The emergency mechanical startup function in the fire protection system is started by manually closing the fire pump, which means that the signal line or the control line of the fire pump control box fails, and the fire pump can be started directly by manually closing the main contactor of the fire pump through the mechanical emergency startup device on the door of the fire pump control box. As long as the fire pump is in the normal power supply condition, no matter what the control line is, it can be forced to start to ensure the timeliness of fire fighting.

机械应急启动装置的启动手柄通常处于停止状态（带锁）。应急报警需要由授权专门人员进行，从接到报警到消防泵的正常运行时间不得超过5min，此时包括专门人员从消防控制室到消防泵房的行走时间，以及水泵从启动到正常工作的时间。更多相关内容就来我们网站http://www.cx-fire.com咨询吧！

The starting handle of the mechanical emergency starting device is usually in a stopped state (with a lock). The emergency alarm shall be carried out by authorized professionals. The time from receiving the alarm to the normal operation of the fire pump shall not exceed 5min, including the travel time of professionals from the fire control room to the fire pump room, and the time from the start of the pump to the normal operation.
