作为火区报警元件，水流指示器具有特别重要的作用。由于其重要的功能和简单的原理，它已被广泛用作强制性产品。那么水流指示器长报警不报警是什么问题呢？

As a fire alarm element, water flow indicator plays a particularly important role. Because of its important function and simple principle, it has been widely used as a mandatory product. So what is the problem that the water flow indicator does not alarm for a long time?

长报警

Long alarm

即无论系统何时进行放水测试，即使确认消防管网的压力水处于静止状态，水流指示器也会始终有水流信号输出，使模块信号灯亮，地板和控制面板。水流指示器动作时主机显示声光报警信号。

That is, whenever the system is tested for water discharge, even if it is confirmed that the pressure water of the fire pipe network is in a static state, the water flow indicator will always have water flow signal output, so that the module signal light is on, and the floor and control panel. When the water flow indicator acts, the host displays an audible and visual alarm signal.

原因可能是厂家的产品质量问题（主要是微动开关问题），但属于产品本身质量的不合格产品比例很小。负责厂家在产品出厂前已经对微动开关进行了开关功能测试，几乎100%可以进行质量控制。

The reason may be the product quality problem of the manufacturer (mainly the microswitch problem), but the proportion of unqualified products belonging to the quality of the product itself is very small. The manufacturer in charge has tested the switch function of the microswitch before the product leaves the factory, and almost 100% of it can be subject to quality control.

当确认微动开关有问题时，可以更换水流指示器外壳中的微动开关，也可以直接更换水流指示器进行安装。

When it is confirmed that there is a problem with the microswitch, the microswitch in the water flow indicator housing can be replaced, or the water flow indicator can be directly replaced for installation.

施工人员安装操作不当造成的长报警现象非常大。水流指示器的桨叶是工厂经过严格计算设计的。不同管径配备不同规格的桨叶。如果施工人员没有按照厂家提供的不同管径安装桨叶；或不匹配不同厂家的桨；或不按说明书要求，错误地上下安装桨叶。或者焊孔时焊接水流指示器留下的焊渣可能会导致水流指示器长时间报警故障。

The long alarm caused by improper installation and operation of construction personnel is very large. The paddle of the water flow indicator is designed by the factory through strict calculation. Different diameters are equipped with blades of different specifications. If the construction personnel do not install the blades according to the different pipe diameters provided by the manufacturer; Or do not match the oars of different manufacturers; Or install the blades up and down incorrectly without following the instructions. Or the welding slag left by the welding water flow indicator during the welding hole may cause the water flow indicator to alarm for a long time.

当确认拨片尺寸使用错误或拨片上下翻转时，应更换并纠正，长报警问题。如果管道开口处有残留焊渣，水流指示器很可能会报警或不报警。因此，必须焊渣，以免影响浆板的来回运动。

When it is confirmed that the dial size is used incorrectly or the dial is turned up and down, it should be replaced and corrected to solve the long alarm problem. If there is residual welding slag at the opening of the pipe, the water flow indicator is likely to alarm or not. Therefore, the welding slag must be removed to avoid affecting the back and forth movement of the pulp board.

不报警

No alarm

系统进行放水测试时，无论流量多少，开启多长时间，水流指示器都会输出，不显示水流信号。

When the system is tested for water discharge, no matter how much the flow is or how long it is opened, the water flow indicator will output and will not display the water flow signal.

这与长警现象是一致的。可能是产品本身的微动开关造成的不合格产品，但是负责任厂商的产品出现这种问题的概率是相当小的。如果确认是不合格产品，只能换货。如果微动开关通断正常，将微动开关的连接支架稍微向桨杆方向移动，使安装与微动开关处于合适的接触距离。

This is consistent with the phenomenon of long-term alarm. It may be the micro switch of the product itself that causes the unqualified products, but the probability of such problems in the products of responsible manufacturers is quite small. If the product is confirmed to be unqualified, it can only be replaced. If the microswitch is turned on and off normally, move the connecting bracket of the microswitch slightly towards the paddle rod to make the installation and the microswitch at a proper contact distance.

川消厂家认为如果施工人员忘记组装桨叶或反方向安装水流指示器（靠水安装），则不会报警。确认这种错误更正并重新安装，问题。

The manufacturer of Chuanxiao believes that if the construction personnel forget to assemble the blades or install the water flow indicator in the opposite direction (installed by water), the alarm will not be given. Confirm that this error is corrected and reinstalled, and the problem is solved.

由于系统本身供水不足，水流指示器不会报警；施工时忘记接水流指示器的两根线；带延时电路的水流指示器必须提供24V直流电源，由于24V直流电压不足也会使水流指示器不工作。

Due to insufficient water supply of the system itself, the water flow indicator will not alarm; Forget to connect the two wires of the water flow indicator during construction; The water flow indicator with time-delay circuit must provide 24V DC power supply, and the insufficient 24V DC voltage will also make the water flow indicator inoperative.
