There are many reasons that may cause the vibration of the unit and the pump room.

Here are a few reasons for the vibration of marine pumps.

1. Electrical. The motor often causes vibration if it is internally misaligned. For example, when an asynchronous motor is running, the magnetic center of the stator and rotor is different and the deviation will cause periodic vibration and noise.

2. Machinery. The poor quality of the motor and the water pump, the rough production, and the damage of the sealing parts will also produce vibration.

3. Hydraulics. The inlet speed and pressure of the pump are unbalanced, and the erosion of the pump caused by the flow and detachment of the working liquid are all factors that easily cause the vibration of the pump, and the noise caused by the vibration is also inevitable. When the pump is opened, stopped or stopped in an emergency, it may cause the pressure change in the water pipe to increase, thus causing the vibration of the marine pump.

4. Other. The design of the unit is defective, matching with other equipment departments, and the submergence of the water pump is incorrect, which makes the conditions when entering the water bad, resulting in cavitation will aggravate the vibration of the pump room.
