What is the reason for the loud pump?
1. There may be electrical imbalance or uneven magnetic force in the water pump motor. For example, the core positions of stator and rotor magnetic force in the working motor are different, or the air gap difference in all directions is higher than the deviation value range.
2. It may also be because the position quality of motor and water pump rotation is relatively poor, resulting in asymmetric axis of the unit or improper installation.
What are the precautions when using a water pump?
1. First of all, the water pipe should be absolutely sealed. Before operation, it is necessary to check whether the joint between the water pump and each water pipe is loose. Always add lubricating oil to the bearing body so as to observe the oil level. If it is an oil-immersed water pump, the oil must be replaced once after 500 hours of operation, and the oil in the motor cavity also needs to be replaced.
2. Check whether the valves of each outlet pipe of the water pump are closed in time and whether there is any error in pressure. When starting the motor, check whether there is any error in steering, open the pressure gauge after operation, and then slowly open the gate valve after the pressure is appropriate. In addition, check whether the water pump motor is overloaded.
3. The flow rate of the water pump should be within the normal range to ensure that the water pump can run with maximum efficiency, thus achieving the effect of energy saving. When the water pump is working, the ambient temperature of the bearing shall not exceed 35 degrees Celsius, and the maximum temperature shall not exceed 80 degrees Celsius. If the sound of the water pump is abnormal, stop the machine immediately for maintenance.
The article concludes: The above are the reasons for the loud sound of the water pump, and what precautions should be taken for the water pump. I hope I can help some friends in need.
