川消消防泵使用维护注意事项

来源:http://www.cx-fire.com/ 日期:2022-08-22

川消小编认为对消防泵进行维修保养,主要的目的是耳确保水泵始终处于良好的运行或备用状态。下面来详细讲讲相关事项吧。
Chuanxiao Xiaobian believes that the main purpose of the maintenance of the fire pump is to ensure that the pump is always in good operation or standby state. Let's talk about related matters in detail.
1.安装消防泵时,电缆线要架空,电源线不要太长。机组下水时切勿使电缆受力,以免引起电源线断裂。消防泵不要沉入泥中,否则会导致电机散热不良而烧坏电机绕组。
1. When installing the fire pump, the cable shall be overhead and the power line shall not be too long. When the unit is launched, do not stress the cable to avoid breaking the power line. Do not sink the fire pump into the mud, otherwise it will cause poor heat dissipation of the motor and burn the motor winding.
2.选购消防泵时应留意其型号、流量和扬程。如选用的规格不恰当,将无法获得足够的出水量,不能发挥机组的效率。另外,还应搞清电机的旋转方向,某些类型的消防泵正转和反转时皆可出水,但反转时出水量小、电流大,其反转会损坏电机绕组。为防止消防泵在水下工作时漏电而引发触电事故,应装有漏电保护开关。
2. Pay attention to its model, flow and lift when purchasing fire pump. If the selected specifications are not appropriate, it will not be possible to obtain sufficient water output and the efficiency of the unit will not be brought into play. In addition, the rotation direction of the motor should also be clear. Some types of fire pumps can discharge water during normal rotation and reverse rotation, but the water output is small and the current is large during reverse rotation, and the reverse transfer will damage the motor winding. In order to prevent electric shock caused by leakage of fire pump when working underwater, leakage protection switch shall be installed.
3.平时多检查电机。如发现下盖有裂纹、橡胶密封环损坏或失效等,应及时更换或修复,以防水渗入机器。
3. Check the motor frequently. In case of cracks on the lower cover, damage or failure of the rubber sealing ring, etc., it shall be replaced or repaired in time to prevent water from penetrating into the machine.

4.尽量避免在低压时开机。电源电压与额定电压不可相差10%,电压过高引起电机过热而烧坏绕组,电压过低则电机转速下降,如达不到额定转速的70%时,启动离心开关会闭合,造成启动绕组长时间通电而发热甚烧坏绕组和电容器。不要频繁地开关电机,这是因为电泵停转时会产生回流,若立即开机,会使电机负载启动,导致启动电流过大而烧坏绕组。
4. Try to avoid starting at low voltage. The power supply voltage shall not differ from the rated voltage by 10%. If the voltage is too high, the motor will overheat and burn out the winding. If the voltage is too low, the motor speed will drop. If the voltage is less than 70% of the rated speed, the startup centrifugal switch will close, causing the startup winding to be energized for a long time and heat up or even burn out the winding and capacitor. Do not switch on and off the motor frequently because the electric pump will generate backflow when it stops running. If it is started immediately, the motor load will start, resulting in excessive starting current and burning the winding.
5.切莫让消防泵长期超负荷运转,不要抽含沙量大的水,电泵脱水运行的时间不宜过长,以免使电机过热而烧毁。机组在作业中,操作者必须随时观察其工作电压和电流是否在铭牌上规定的数值内,若不符合应使电机停止运转,找出原因并排除故障。
5. Do not allow the fire pump to operate overloaded for a long time. Do not pump water with large sand content. The dehydration operation time of the electric pump should not be too long to avoid overheating and burning of the motor. During the operation of the unit, the operator must observe whether the working voltage and current are within the values specified on the nameplate at any time. If not, the motor shall be stopped to find out the cause and eliminate the fault.
此外消防用泵不能以一般使用场合配套的泵的功率来配套消防泵组,消防泵毕竞有其特殊的要求,特别是功率的余量上,在很多情况下用户是难以接受的,强调这一点是保证消防泵的运行所必须的。有疑问可以来我们网站http://www.cx-fire.com咨询了解。
In addition, the fire pump cannot be matched with the fire pump set with the power of the pump matched in the general use. The fire pump Bijing has its special safety requirements, especially the power margin, which is difficult for users to accept in many cases. It is necessary to emphasize this point to ensure the safe operation of the fire pump. If you have any questions, you can come to our website http://www.cx-fire.com Consultation and understanding.
