How to judge the quality of the centrifugal fan
1. Whether the fan performance meets the nominal wind pressure air volume and meets the nominal type energy, it will reach the pumping air volume required by the actual system;
2. The fan efficiency is not high, the fan efficiency is high, the power is low, and the fan efficiency is low;
3. The vibration value of the bearing part is not high, the vibration value is high, the fan bearing is easy to be damaged, the vibration value is low, and the bearing life is long;
4. How the noise is running, noise is environmental pollution, affecting work mood, and also energy consumption;
5. Whether to consider the convenience of maintenance, the fan is required to be regularly maintained, and the oil hole, drain hole, manhole and bearing are easy to disassemble;
6. Generally speaking, the appearance of the fan can be seen as good or bad. The more attention is paid to the details, the fan is generally good.
