Reasons for the shutdown of sanace cooling fan during use
As the fan is widely used in enterprise production and life, and some noise is inevitable when the fan is working, what is the noise source of the cooling fan in detail? How to carry out maintenance at ordinary times?
1. The noise comes from the system impedance
Generally speaking, the total inlet air volume and outlet air volume of a casing of the cooling fan will account for 60% ~ 80% of the total system impedance, which means that the greater the air flow, the greater the noise. If you want to reduce the noise, you must reduce the system impedance.
2. Disturbed by the airflow
If the noise of wearing the fan suddenly increases, you can consider whether it is the cause of airflow disturbance. Generally, if the airflow encounters obstacles, it will cause turbulence and lead to noise, so it must be avoided at the air outlet, inlet and outlet.
3. Caused by the problem of speed dimension
According to past experience, the noise generated by the cooling fan at high speed will be greater than that at low speed. At the same time, the noise generated by the fan with smaller size and faster speed will be much greater than that of the fan with larger size and slower speed.
4. Due to voltage variation
The noise of the fan may also be caused by the change of voltage. Generally speaking, the higher the voltage of the fan, the higher the speed, and the greater the noise. Therefore, each part should be optimized and deeply designed in the design, so as to better reduce the noise.
In fact, there are many places to pay attention to when maintaining the heating fan. For example, the fan must not be stored in a humid environment. In addition, the fan should also be careful in handling. Some collisions during handling will cause continuous damage. In addition, for users, the cooling fan should be cleaned regularly, At the same time, it should also be noted that there should be no accumulation of sundries at the air inlet and outlet of the cooling fan. In addition, when the cooling fan has excessive scalding or abnormal tripping of the motor, it should be closed and repaired in time.
