<p>The object of the invention is a method for arranging the fluid lubrication of bearings (6) of a rotor (2) of a closed or hermetic high-speed machine (1), especially a small-size power plant based on the Organic Rankine Cycle (ORC) process, i.e. an energy converter, comprising a turbine (3), a generator (4), and possibly a main feed pump (5) installed on a joint rotor (2), wherein organic circulating medium of the process is used for lubrication. According to the invention, in a stoppage situation of the primary circulation in the main line (10) of the energy converter, the fluid lubrication of the bearings (6) of the rotor (2) is secured by pressurized circulating medium accumulated in the vaporizer (11), such as a boiler, process furnace, ceramic furnace, or a corresponding heat source, as a result of the closing of the main operational valve.</p> |
