消防設(shè)備中，消防泵體積較小，作用較大，消防上常用到它，它的密封性好，使用起來，在此
川消小編提醒您，消防泵的安裝參考10大使用要領(lǐng)！
In the fire fighting equipment, the fire pump is small in size and has a large role. It is commonly used in fire fighting. Its sealing is good and it is safe to use. Here, we remind you that the installation of the fire pump should refer to the top 10 tips for use!
要領(lǐng)一、安裝時(shí)，應(yīng)選距輸送液近的地方，使消防泵裝在具有小的吸入高度和短的吸入管路處。
Key point 1. During installation, the place close to the liquid delivery shall be selected, so that the fire pump is installed at the place with small suction height and short suction pipeline.
要領(lǐng)二、當(dāng)消防泵使用在振動要求比較嚴(yán)格的地方，可以使用減振器(墊)，須按廠家的指導(dǎo)進(jìn)行
Key point II. When the fire pump is used in places with strict vibration requirements, the shock absorber (pad) can be used, and the manufacturer's instructions must be followed
要領(lǐng)三、川消消防泵的安裝應(yīng)可靠固定，緊靠消防泵法蘭處的管路支承應(yīng)有足夠的剛性，不得讓消防泵承受管道的重量壓力。
Key point 3. The installation of fire pump of Sichuan Fire Pump shall be reliable and fixed. The pipeline support close to the fire pump flange shall be rigid enough, and the fire pump shall not bear the weight pressure of the pipeline.
要領(lǐng)四、消防泵組的安裝應(yīng)避免太陽的直射和雨淋。
Key point 4. The installation of fire pump unit shall avoid direct sunlight and rain.
要領(lǐng)五、消防泵的進(jìn)口應(yīng)安裝真空壓力表，出口法蘭應(yīng)安裝壓力表，以觀察和控制泵的運(yùn)行情況。壓力表的量程應(yīng)為實(shí)際壓力的2-3倍為宜。
Key point 5. Vacuum pressure gauge shall be installed at the inlet of the fire pump and pressure gauge shall be installed at the outlet flange to observe and control the operation of the pump. The range of the pressure gauge should be 2-3 times of the actual pressure.
要領(lǐng)六、消防泵的進(jìn)口和出口管路應(yīng)裝設(shè)閘閥，以方便維修和運(yùn)行調(diào)節(jié)。
Key point 6. The inlet and outlet pipelines of the fire pump shall be equipped with gate valves to facilitate maintenance and operation adjustment.
要領(lǐng)七、接線:須按銘牌要求正確接線，接線時(shí)，接線端須牢固，不允許有松動，否則，會造成接觸不良而導(dǎo)致缺相燒機(jī)。為保證電機(jī)可靠運(yùn)行，電器開關(guān)處應(yīng)裝上過載保護(hù)裝置，并根據(jù)電機(jī)銘牌上的電流要求調(diào)整保護(hù)裝置的設(shè)定值的大小。
Key point VII. Wiring: The wiring must be correct according to the requirements of the nameplate. When wiring, the terminal must be firm, and no looseness is allowed. Otherwise, it will cause poor contact and lead to phase loss and burning. To ensure reliable operation of the motor, overload protection device shall be installed at the electrical switch, and the setting value of the protection device shall be adjusted according to the current requirements on the motor nameplate.
要領(lǐng)八、在吸入狀態(tài)(水位低于葉輪軸線或水位低于消防泵吸入口軸線)，標(biāo)準(zhǔn)大氣壓時(shí)，消防泵的安裝高度H安=10-(NPSH)r-0.5-hw,hw為吸入管路的阻力損失(公式中的計(jì)算單位:rn)
Main point VIII. In the suction state (the water level is lower than the impeller axis or the water level is lower than the axis of the fire pump suction inlet), when the standard atmospheric pressure is applied, the installation height of the fire pump H A=10 - (NPSH) r-0.5-hw, hw is the resistance loss of the suction pipeline (the calculation unit in the formula is rn)
要領(lǐng)九、若從水池中抽水時(shí)，消防泵吸入口前的直管段長度不應(yīng)小于入口直徑的3倍，吸入管口浸入水面下的深度應(yīng)大于入口直徑的1_5倍且不小于500mm。吸入管口距池壁距離應(yīng)大于1.5倍口徑，距池底應(yīng)大于1.5倍口徑且不小于500mm，并應(yīng)加設(shè)濾網(wǎng)，濾網(wǎng)總面積不應(yīng)小于吸入管口面積的2~3倍。
Key point 9. If water is pumped from the pool, the length of the straight pipe section in front of the fire pump suction port shall not be less than 3 times the inlet diameter, and the depth of the suction pipe port immersed in the water surface shall be greater than 1% of the inlet diameter_ 5 times and no less than 500mm. The distance from the suction pipe orifice to the tank wall shall be more than 1.5 times the diameter, and the distance from the tank bottom shall be more than 1.5 times the diameter and not less than 500mm. A filter screen shall be added, and the total area of the filter screen shall not be less than 2-3 times the area of the suction pipe orifice.
要領(lǐng)十、為了便于啟動前向消防泵內(nèi)灌水，可在止回閥兩端加設(shè)一個(gè)旁通閥，在川消消防泵啟動前打開旁通閥向消防泵內(nèi)灌水，注滿后關(guān)閉，方便使用。對用于高層樓房供水或出口壓力大于·0.2MPa的消防泵，除在排出口裝有閘閥外，還應(yīng)在消防泵出口和閘閥間裝有止回閥，以免突然停電高壓水回流導(dǎo)致葉輪損壞。
Key point 10. In order to fill the fire pump with water before starting, a bypass valve can be added at both ends of the check valve. Before starting the Sichuan Fire Pump, open the bypass valve to fill the fire pump with water, and then close it after filling to facilitate use. For the fire pump used for water supply of high-rise buildings or with outlet pressure greater than 0.2MPa, in addition to the gate valve at the outlet, a check valve should also be installed between the fire pump outlet and the gate valve to avoid damage to the impeller caused by sudden power failure and high pressure water backflow.
