对含尘离心风机变工况运行与叶片磨损关系作了系统的分析,用Lagrange法计算了变工况运行时固粒在叶轮流道中的运动轨迹和叶片表面磨损状况,发现转速变化对大粒径粒子运动产生较大影响,流量变化对小粒径粒子运动产生较大影响,流量、转速同步调节时叶轮磨损形态具有“相仿性”。 The relationship between variable load centrifugal fan operation and blade wear was systematically analyzed. The Lagrangian method was used to calculate the motion trajectory of the solid particles in the impeller runner and the wear condition of the blade surface under varying working conditions. Diameter particle movement have a greater impact, the flow changes on the particle size of a small particle movement have a greater impact, flow, speed synchronous adjustment impeller wear morphology has a “similar.”
