消防泵是指符合標準的消防泵性能要求和試驗方法GB普通清水泵或專用消防泵6245。在給排水消防設計中，合理設計消防泵非常重要，消防泵的可靠啟動泵也應得到有效保證，其重要性不言而喻。今天川消小編帶你了解消防泵的啟泵的六大控制原理。

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開關啟動泵

High fire water tank outlet pipe flow switch starts pump

流量開關又稱水流開關、流量傳感器和水流動作閥，是一種傳感控制器，利用各種原理測量管道中介質的流量，并及時傳輸給后端設備，用于開關通信信號。當流量高于或低于設定點時，流量開關觸發報警信號，系統可以在獲得信號后做出相應的指示動作。

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.

消防泵出水管壓力開關啟動泵

Pressure switch of fire pump outlet pipe starts the pump

壓力開關是指通過特殊的CPU模塊化信號處理技術，實現介質壓力的檢測、顯示、報警和控制信號輸出，采用高精度、高穩定性的壓力傳感器和傳輸線路。

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.

在水消防系統中，低壓開關一般設置在消防泵出水管上。當流量開關失效時，水消防系統繼續依靠水箱和穩壓泵提供水量和水壓滅火，穩壓泵不及時補水會導致系統壓力下降。或僅依靠消防水箱靜水壓力滅火，水箱水位下降，消防泵出水壓力開關感應壓力下降，壓力開關動作。當流量開關失效時，無論消防水箱是否設置穩壓泵，供水過程中的壓力都會下降，壓力開關的設置就是基于這一基本原理。

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.

報警閥壓力開關啟動泵

Alarm valve pressure switch starts pump

濕式報警閥組的壓力開關是安裝在延遲器與水力報警管道之間的壓力水流探測開關。報警閥打開后，報警管道充水，流向水力報警鈴。壓力開關在接收水壓時接通電觸點，并給出電接點信號。報警閥壓力開關的結構和要求是：當系統中出現一個或多個噴嘴流量時，壓力開關動作自動啟動噴淋泵，并發出火災報警信號。當流量停止時，電觸點斷開。

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.

手動啟泵

Manually start the pump

手動啟泵功能應設置在消防控制室或消防泵房。為保證消防控制室啟動泵的可靠性，采用硬拉線直接啟動消防泵，可盡量減少干擾和風險。在情況下，由于聯動控制存在失效的可能性，如軟件受病毒侵害等危險，導致弱電信號總線無法移動。由此可見，手動直接啟泵是消防啟泵必不可少的防線。消防控制室的手動控制盤設置在消防控制室的消防聯動控制器上。

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.

自動啟泵

Automatic pump start

消防設備需要自動火災報警系統的聯動控制，其聯動觸發信號應采用兩個獨立的報警觸發裝置報警信號的“和”邏輯組合。聯動觸發信號包括溫度（煙霧）火災探測器信號、手動火災報警按鈕信號、壓力（流量）開關動作信號、消火栓按鈕動作信號燈。聯鎖控制模式和消防聯動控制器（聯動控制模式）均可實現消防泵的自動啟動。

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.

機械應急啟動泵

Mechanical emergency start pump

弱電信號和硬拉線，如壓力開關和流量開關，都是通過繼電器自動啟動消防泵的。消防系統中的應急機械啟動功能是通過手動關閉消防泵啟動的，是指信號線或消防泵控制箱的控制線故障，通過消防泵控制箱門上的機械應急啟動裝置，直接手動關閉消防泵的主接觸器啟動消防泵。只要消防泵在正常供電條件下，無論控制線路如何，都可以強制啟動，以確保消防的及時性。

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.

機械應急啟動裝置的啟動手柄通常處于停止狀態（帶鎖）。應急報警需要由授權專門人員進行，從接到報警到消防泵的正常運行時間不得超過5min，此時包括專門人員從消防控制室到消防泵房的行走時間，以及水泵從啟動到正常工作的時間。更多相關內容就來我們網站http://www.xintli.net咨詢吧！

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.
