摘要
针对轴流风机失速产生的条件及保护设置机理,对失速保护拒动和误动的原因进行了分析。提出了通过将失速探针增加到3个,保护采取"三取二"设置,将取样管改变和增加伴热的方法,可以有效地防止失速保护拒动和误动,保证轴流风机的安全。
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.
