In recent years, with the continuous development of industrialization, fan has been gradually used in various industries of ventilation and ventilation. With the continuous change of production demand, centrifugal fans gradually enter the fan market, and because of its unique performance characteristics are recognized by the majority of manufacturers, centrifugal fan constant pressure variable flow performance is the biggest flash point of its products. This paper introduces several methods to judge the performance of centrifugal fan.

In large enterprises, the performance of fan directly affects the production efficiency of the whole workshop. In warehouse storage, fan ventilation is also an indispensable step for food and drug storage. So the choice of fan in production, life is very important.

1. Whether the performance of the fan can meet the standard wind pressure and air volume, only the fan that meets the standard can reach the required volume of air.

2. The working efficiency of the fan is also discussed. The selection standard is to select the fan with high efficiency under the condition of low power consumption.

3. Whether the matching mechanism of every part of the fan is strictly in accordance with the national standard, the matching of bearing and shaft, the matching of hole and shaft should be selected, and the lower the vibration value, the longer the life of the fan.

4. The working performance of the machine is mainly reflected in the magnitude of the oscillating value, the noise and the noise of the fan. If the noise reaches a certain level, it will affect the working mood of the staff and reduce the working efficiency.

5. The convenience of maintenance should be taken into account when selecting, the fan is electric equipment need to be maintained regularly, generally requires convenient refueling hole and repair drain hole, and bearing is convenient to disassemble and assemble.

6, generally speaking, from the appearance can see the fan quality, when observing should pay attention to the detail position, in addition, must buy the fan to seek the market reputation generally to be good, the management time is long, the sale volume is big, the scale big manufacturer.
