For the rotor of the radial turbine power generation system, the main concerned sealing part is the rotor seal of the compressor end and the turbine end, in particular to the rotor seal structure of the turbine end, and the sealing difficulty is also high due to the large pressure difference and high temperature of the sealing working medium of the turbine end.

The sealing mode has the advantages of simple structure, small leakage amount, low manufacturing cost and the like, but also has the problems of short service life and the like, and particularly when the sealing mode is used for sealing a high-temperature end, the sealing ring is easy to lose elasticity when working for a long time, so that the sealing failure is caused, and the sealing mode is a main factor limiting the service life of a system.
Aiming at the reliability and service life requirements of the radial flow turbine power generation system, the high-pressure gradient efficient sealing structure of the rotor of the radial flow turbine power generation system is provided, and through reasonably designing the sealing structure of the rotor, the reliable sealing between the rotor and a static part can be realized, the long-time working requirement can be met, and the high reliability and long service life targets of the structure of the turbine power generation system are realized.
