摘要
Abstract
With the rapid development of the industrial turbine industry,unit speeds are demanded to be increasing.To ensure the safe operation of insert-type steam seals at high rotor speeds,The riveting process is employed in rotor seal design to prevent seal tooth detachment in the industry predominantly.The effectiveness of the riveting process was studied through friction tests on insert-type steam seal tooth of various specifications.The results indicate that the riveting effect is significantly influenced by human factors,and multiple riveting operations can increase the friction force acting on the seal.Furthermore,a simplified calculation method is proposed for the centrifugal force acting on insert-type steam seal.The research findings can provide reference for the design of insert-type steam seals in high speed turbine units.关键词
