离心风机在运转过程中，其通风除尘与气力输送系统经常会出现风量过大或过小的现象，严重影响设备的使用效率，其中导致这一现象的原因有很多，为更好的进行设备解决，维持原有的使用效率，接下来就其导致风量过大过小的原因进行介绍。

During the operation of centrifugal fan, its ventilation, dust removal and pneumatic conveying system often have the phenomenon of too large or too small air volume, which seriously affects the use efficiency of the equipment. There are many reasons for this phenomenon. In order to better solve the equipment and maintain the original use efficiency, next, the reasons for too large or too small air volume are introduced.

离心风机出现风量过大或过小的原因

Reasons for excessive or small air volume of centrifugal fan

1、风机的管道系统的实际值与设计值相差过大；

1. The actual value of the pipeline system of the fan is too different from the design value;

2、风机的电源电压出现波动或频率不稳定，导致风机转速出现变化，进而使其风量发生变化；

2. The power supply voltage of the fan fluctuates or the frequency is unstable, resulting in the change of the fan speed and the change of the air volume;

3、风机的管道系统堵塞，会使风量在较长的时间内逐渐减小，或在短时间内突然减小。

3. If the duct system of the fan is blocked, the air volume will gradually decrease in a long time or suddenly decrease in a short time.

离心风机安装后，正式运转时若出现风量过大或过小现象，上述已经对其原因进行了分析，并对整个通风除尘系统进行必要的调整，以此来确保风机的使用效率。

After the centrifugal fan is installed, if the air volume is too large or too small during formal operation, the above reasons have been analyzed, and the whole ventilation and dust removal system has been adjusted as necessary to ensure the service efficiency of the fan.
