This paper analyzes the causes upon refusing act & incorrect operation of stall protection aiming at conditions and safeguard setting mechanization that produces by stall of axial flow fan. It can prevent refusing act & incorrect operation of stall protection effectively and pledge the safety of axial flow fan with the idea of increasing the stall probe into three, the adoption of “two-out-of -three”protection setting, conversion on sampling pipe and heat tracing adding.
