通过叶轮的形式介绍及其选择方法的简述,根据搅拌目的和叶轮功能的相互验证,说明此次选煤用1.5搅拌桶所选叶轮的形式是合理的。并对比拟放大后的叶轮进行了强度校核,结果表明叶轮的尺寸结构设计满足强度要求。
According to the introduction of the impeller and the brief description of its selection method, according to the mutual validation of the purpose of stirring and the impeller function, it is reasonable to use the impeller of the 1.5 mixing drum selected by the coal preparation. The strength comparison of impellers to be enlarged is carried out. The results show that the size structure of the impellers meets the strength requirements.
