| Abstract: | Honeycomb seal has excellent sealing and damper performance.It can improve the integral performance of turbo machineries in petrochemical industries.Technological transformations were completed for axial compressor,flue gas turbine and steam turbine with honeycomb seal technology.Problems such as seal leakage,lubricant oil deteriorated by water,rotary blades flushed by water drops were solved effectively.The available transformation effects showed that honeycomb seal could improve the operating efficiency and stability of turbo machineries,and had an expansive application prospect in petrochemical industries. |
