fish tank submersible pump sound, then there are generally two solutions.The first is to reduce resonance, which is due to its contact with some objects in the cylinder, resulting in the sound being amplified, which can be achieved by adjusting the position.The second is to replace the submersible pump, some pump quality is relatively poor, so there will be greater noise, for some frequency conversion pump, the sound is much smaller.
1, current sound: motor current sound will produce noise, it sounds buzzing sound.This situation can not be solved by individuals, because it is the problem of internal structure, easy changes may lead to submersible pump scrap, it is recommended to directly replace a new one.
2. Axis friction: When the submersible pump works, the rotor of the pump is lifted by magnetic force, and the bottom supports the axis, which can prevent the rotor from lagging behind due to water flow, but it will also produce certain friction, so it will make noise.Usually the life of the axis is about a year, and it will be replaced after grinding.
3. Rotor friction: The specific friction of the turbine centrifugal water pump. As long as it is this kind of pump, this kind of noise can not be avoided. However, as long as the radian of the rotor is well designed, the noise volume can also be reduced through the smooth surface.
