消防泵是指符合標(biāo)準(zhǔn)的消防泵性能要求和試驗(yàn)方法GB普通清水泵或?qū)Ｓ孟辣?245,。在給排水消防設(shè)計(jì)中，合理設(shè)計(jì)消防泵非常重要,，消防泵的可靠啟動(dòng)泵也應(yīng)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(guān)啟動(dòng)泵
High fire water tank outlet pipe flow switch starts pump
流量開關(guān)又稱水流開關(guān),、流量傳感器和水流動(dòng)作閥，是一種傳感控制器,，利用各種原理測量管道中介質(zhì)的流量,，并及時(shí)傳輸給后端設(shè)備，用于開關(guān)通信信號(hào),。當(dāng)流量高于或低于設(shè)定點(diǎn)時(shí),，流量開關(guān)觸發(fā)報(bào)警信號(hào)，系統(tǒng)可以在獲得信號(hào)后做出相應(yīng)的指示動(dòng)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(guān)啟動(dòng)泵
Pressure switch of fire pump outlet pipe starts the pump
壓力開關(guān)是指通過特殊的CPU模塊化信號(hào)處理技術(shù),，實(shí)現(xiàn)介質(zhì)壓力的檢測、顯示,、報(bào)警和控制信號(hào)輸出,，采用高精度、高穩(wěn)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(tǒng)中,，低壓開關(guān)一般設(shè)置在消防泵出水管上。當(dāng)流量開關(guān)失效時(shí),，水消防系統(tǒng)繼續(xù)依靠水箱和穩(wěn)壓泵提供水量和水壓滅火,，穩(wěn)壓泵不及時(shí)補(bǔ)水會(huì)導(dǎo)致系統(tǒng)壓力下降?；騼H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(guān)感應(yīng)壓力下降，壓力開關(guān)動(dòng)作,。當(dāng)流量開關(guān)失效時(shí),，無論消防水箱是否設(shè)置穩(wěn)壓泵，供水過程中的壓力都會(huì)下降,，壓力開關(guān)的設(shè)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(bào)警閥壓力開關(guān)啟動(dòng)泵
Alarm valve pressure switch starts pump
濕式報(bào)警閥組的壓力開關(guān)是安裝在延遲器與水力報(bào)警管道之間的壓力水流探測開關(guān)。報(bào)警閥打開后,，報(bào)警管道充水,，流向水力報(bào)警鈴。壓力開關(guān)在接收水壓時(shí)接通電觸點(diǎn),，并給出電接點(diǎn)信號(hào),。報(bào)警閥壓力開關(guān)的結(jié)構(gòu)和要求是：當(dāng)系統(tǒng)中出現(xiàn)一個(gè)或多個(gè)噴嘴流量時(shí)，壓力開關(guān)動(dòng)作自動(dòng)啟動(dòng)噴淋泵,，并發(fā)出火災(zāi)報(bào)警信號(hào)。當(dāng)流量停止時(shí),，電觸點(diǎn)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(dòng)啟泵
Manually start the pump
手動(dòng)啟泵功能應(yīng)設(shè)置在消防控制室或消防泵房。為保證消防控制室啟動(dòng)泵的可靠性,，采用硬拉線直接啟動(dòng)消防泵,，可盡量減少干擾和風(fēng)險(xiǎn)。在情況下,，由于聯(lián)動(dòng)控制存在失效的可能性,，如軟件受病毒侵害等危險(xiǎn)，導(dǎo)致弱電信號(hào)總線無法移動(dòng),。由此可見,，手動(dòng)直接啟泵是消防啟泵必不可少的防線。消防控制室的手動(dòng)控制盤設(shè)置在消防控制室的消防聯(lián)動(dòng)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(dòng)啟泵
Automatic pump start
消防設(shè)備需要自動(dòng)火災(zāi)報(bào)警系統(tǒng)的聯(lián)動(dòng)控制,，其聯(lián)動(dòng)觸發(fā)信號(hào)應(yīng)采用兩個(gè)獨(dú)立的報(bào)警觸發(fā)裝置報(bào)警信號(hào)的“和”邏輯組合。聯(lián)動(dòng)觸發(fā)信號(hào)包括溫度（煙霧）火災(zāi)探測器信號(hào),、手動(dòng)火災(zāi)報(bào)警按鈕信號(hào),、壓力（流量）開關(guān)動(dòng)作信號(hào)、消火栓按鈕動(dòng)作信號(hào)燈,。聯(lián)鎖控制模式和消防聯(lián)動(dòng)控制器（聯(lián)動(dòng)控制模式）均可實(shí)現(xiàn)消防泵的自動(dòng)啟動(dòng),。
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(jī)械應(yīng)急啟動(dòng)泵
Mechanical emergency start pump
弱電信號(hào)和硬拉線，如壓力開關(guān)和流量開關(guān),，都是通過繼電器自動(dòng)啟動(dòng)消防泵的,。消防系統(tǒng)中的應(yīng)急機(jī)械啟動(dòng)功能是通過手動(dòng)關(guān)閉消防泵啟動(dòng)的,，是指信號(hào)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(jī)械應(yīng)急啟動(dòng)裝置,，直接手動(dòng)關(guān)閉消防泵的主接觸器啟動(dòng)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(qiáng)制啟動(dòng),，以確保消防的及時(shí)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(jī)械應(yīng)急啟動(dòng)裝置的啟動(dòng)手柄通常處于停止?fàn)顟B(tài)（帶鎖）,。應(yīng)急報(bào)警需要由授權(quán)專門人員進(jìn)行,，從接到報(bào)警到消防泵的正常運(yùn)行時(shí)間不得超過5min，此時(shí)包括專門人員從消防控制室到消防泵房的行走時(shí)間,，以及水泵從啟動(dòng)到正常工作的時(shí)間,。更多相關(guān)內(nèi)容就來我們網(wǎng)站
