    • A cavitation prevention structure for a centrifugal compressor is provided to prevent damage to an oil pump by canceling the flow of refrigerant gas with the spraying pressure. A cavitation prevention structure for a centrifugal compressor(10) comprises a transmission part(14), an oil pump(24), and a pipe(30). The transmission part includes a driving gear(16), which is engaged with a driven gear(18), inside a housing in order to raise refrigerant gas into high pressure. The oil pump is installed at the lower part of the transmission part to be submerged in working fluid. The pipe sprays portions of the refrigerant gas and the working fluid compressed from a compressor to the transmission part. The cavitation is prevented by canceling the flow of the refrigerant gas due to the rotation of the transmission part with the spraying pressure from a spray hole(32).

    • PURPOSE: An organic fluid turbine generating system capable of preventing the penetration of working fluid is provided to prevent damage to a bearing caused by the leakage of working fluid through a gap between a generator housing and a rotary shaft. CONSTITUTION: An organic fluid turbine generating system comprises a turbine and a generator. The turbine transfers the rotation of a turbine blade(22) by working fluid to a generator rotor through a rotary shaft(25). The generator implements power generation. The rotary shaft is equipped with a disk-shaped end block(27). A first flow path(26a) is formed in a gap between the turbine housing and the rotary shaft, a second flow path(26b) communicated with the first flow path is extended along the rotary shaft, and a third flow path(26c) communicated with the second flow path is formed in the diameter direction of the end block.
