Reasons for the stall of the axial flow fans

using an axial flow fan ? What are the reasons for the stall of an axial flow fan? Today, Xiaobian will introduce it to you, let’s take a look at the following article.

1. The air volume on both sides of the axial fan is unbalanced, and the fan stall generally occurs during the parallel operation of the fans; during the low-load operation and the fan on the lower load side of the fan in parallel operation is prone to stall;

2. The fan output is low, the air volume at the fan outlet is small, and the fan stall is prone to occur in the operating conditions of high wind pressure;

3. The characteristics of the air duct change, resulting in low air volume and high wind pressure operating conditions, which are prone to fan stall.
