摘要
介绍了D70-81型离心式鼓风机的结构、性能,离心式鼓风机平衡鼓和叶轮轮毂损坏情况,从密封间隙设计、材料、操作、工艺、振动方面分析了平衡鼓和叶轮轮毂抱死损坏的原因,并提出通过保证轴承座与隔板同心度,按照实验测定ZL104的膨胀系数,重新调整平衡鼓和叶轮密封间隙,来延长离心式鼓风机运行周期。
The hub of the impeller balancing drum and structure of type 1970 -81centrifugal blower, centrifugal blower performance, balance drum and the damage of sealing clearance were introduced. From design, material, process, operation, vibration, impeller hub locking damage causes were analyzed. Through the guarantee of the bearing seat and the diaphragm concentricity, according to experimental determination ZLlO4expansion coefficient, the balance of the drum and impeller sealing clearance was readjusted to prolong the
