一种撬装式多级小背压汽轮机的设计探讨

Design of Slid-mounted Multistage Backpressure Turbine

介绍了一种高转速的小背压汽轮机,通流部分采用小直径、小焓降的多级设计,比单级小机和常规的3 000 r/min汽轮机效率更高,整体采用底盘油站撬装式设计,体积小、集成度高,可广泛用于驱动各类发电机、压缩机、风机、水泵,可减少土建、安装和使用成本,为用户带来更多的经济效益。

In this article,one kind of high rotary speed low backpressure turbine was introduced,in this kind of turbine,multistage with small diameter impeller and small enthalpy drop is designed for the flowing part,which makes the efficiency higher than that of single stage turbine and 3 000 r/min turbine.Slid-mounted design is used that whole turbine and its oil system are mounted on baseplate.This structure has the advantages of small volume,high integration and low costs in inffastructural engineering,installation and application,and this kind of turbine can be used in various motors,compressors,blowers and pumps,and more economic benefits may results from its application.
