来源:http://www.cx-fire.com/ 日期:2022-11-22

消防设备中,消防泵体积较小,作用较大,消防上常用到它,它的密封性好,使用起来,在此川消小编提醒您,消防泵的安装参考10大使用要领!
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!
要领一、安装时,应选距输送液近的地方,使消防泵装在具有小的吸入高度和短的吸入管路处。
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.
要领二、当消防泵使用在振动要求比较严格的地方,可以使用减振器(垫),须按厂家的指导进行
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
要领三、川消消防泵的安装应可靠固定,紧靠消防泵法兰处的管路支承应有足够的刚性,不得让消防泵承受管道的重量压力。
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.
要领四、消防泵组的安装应避免太阳的直射和雨淋。
Key point 4. The installation of fire pump unit shall avoid direct sunlight and rain.
要领五、消防泵的进口应安装真空压力表,出口法兰应安装压力表,以观察和控制泵的运行情况。压力表的量程应为实际压力的2-3倍为宜。
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.

要领六、消防泵的进口和出口管路应装设闸阀,以方便维修和运行调节。
Key point 6. The inlet and outlet pipelines of the fire pump shall be equipped with gate valves to facilitate maintenance and operation adjustment.
要领七、接线:须按铭牌要求正确接线,接线时,接线端须牢固,不允许有松动,否则,会造成接触不良而导致缺相烧机。为保证电机可靠运行,电器开关处应装上过载保护装置,并根据电机铭牌上的电流要求调整保护装置的设定值的大小。
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.
要领八、在吸入状态(水位低于叶轮轴线或水位低于消防泵吸入口轴线),标准大气压时,消防泵的安装高度H安=10-(NPSH)r-0.5-hw,hw为吸入管路的阻力损失(公式中的计算单位: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)
要领九、若从水池中抽水时,消防泵吸入口前的直管段长度不应小于入口直径的3倍,吸入管口浸入水面下的深度应大于入口直径的1_5倍且不小于500mm。吸入管口距池壁距离应大于1.5倍口径,距池底应大于1.5倍口径且不小于500mm,并应加设滤网,滤网总面积不应小于吸入管口面积的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.
要领十、为了便于启动前向消防泵内灌水,可在止回阀两端加设一个旁通阀,在川消消防泵启动前打开旁通阀向消防泵内灌水,注满后关闭,方便使用。对用于高层楼房供水或出口压力大于·0.2MPa的消防泵,除在排出口装有闸阀外,还应在消防泵出口和闸阀间装有止回阀,以免突然停电高压水回流导致叶轮损坏。
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.
