        the reason why the electric fire pump is too noisy is that there are only a few problems

          What if the electric fire pump is noisy? Is the fire pump too noisy? In fact, the reason why the electric fire pump is too noisy is that there are only a few problems:
          1. The installation is not up to standard, resulting in abnormal noise in the pipeline fire pump.
          When the electric fire pump is working, the vibration frequency is high, so it needs to be well fixed when it is installed. If the village is loose between the pump body and the base or the base and the base when installing the pipeline fire pump, the transmission shaft between the pump body and the motor of the pipeline pump will bend, reducing the coaxiality and causing fire protection. The imbalance of the rotor of the water pump is one of the phenomena of noise from the fire pump. To improve this phenomenon, the pump shaft of the fire pump needs to be balanced and then reinstalled. Finally, the base of the pump is reinforced.
          2. Then there is a certain effect on the working condition of the electric fire pump that produces noise.
          For example, if a small-flow pipeline fire pump is forced to increase the power and increase the original flow rate, the vibration of the fire pump will be generated. Therefore, Hebei Qinhuangdao Langfang Quzhou and other areas should be implemented according to the use of water pumps when using pipeline fire pumps or other types of pumps to prevent noise from the pump and affect the service life of the fire pump. The best solution is to use the pump according to the instructions for use. If it affects the efficiency of use, it is recommended to replace the appropriate pipeline fire pump for use.
          3. When there is noise in the pipeline fire pump, the most likely phenomenon is that the rotor of the fire pump is unbalanced.
          Because the effluent of the fire pump mainly depends on the high-speed rotation of the rotor, when the rotor is unbalanced for some reasons, the fire pump will deviate from the original trajectory during the rotation process, resulting in the pipeline fire pump. . When it is determined that the rotor is faulty, it is mainly to replace the rotor of the water pump or to balance the rotor blades of the water pump to find the balance difference.
          4. The bearing of the electric fire pump is damaged.
          Bearing damage generally does not occur on the body of the pipeline fire pump. If there is a problem with the quality of the pump, or because there is a hard object entering the pump body of the pipeline pump, the bearing is damaged, so that the rotor does not start to stabilize, resulting in There is noise in the pipeline fire pump.
          5. The blockage of the impeller flow path will also cause noise in the fire pump.
          When the internal flow passage of the fire pump is blocked by foreign matter, the resistance of the fire pump impeller is uneven, which causes the vibration of the fire pump. Therefore, it is necessary to periodically disassemble and maintain the fire pump to prevent foreign matter from clogging the pipeline.
          6. Finally, it is cavitation. The cavitation phenomenon occurs in any kind of water pump, but some are obviously not obvious.
          If cavitation occurs, consider raising the fire pump or increasing the pressure inside the pipe. If the cavitation phenomenon cannot be changed, the model of the fire pump needs to be redesigned and replaced.
