TURBO COMPRESSOR AND TURBO REFRIGERATOR |
| 摘要 |
A turbo compressor that has a compression stage provided with an impeller that rotates; a housing provided with a gear unit accommodation space that accommodates lubricating oil and accommodates a large diameter gear that transmits rotating force to the impeller, an IGV accommodation space in which the ambient pressure is lower than the gear unit accommodation space, and a gap that brings the IGV accommodation space and the air intake side of a first compression stage into communication; a pressure equalizing tube that causes a gas to circulate from the gear unit accommodation space toward the IGV accommodation space; and a second oil separating device that separates, in the IGV accommodation space, the lubricating oil contained in the gas. |

1. A turbo compressor comprising:
a compression stage provided with an impeller that rotates; a housing provided with a first space that accommodates lubricating oil and accommodates a gear member that transmits rotating force to the impeller, a second space in which the ambient pressure is lower than the first space, and a gap that brings the second space and the air intake side of the compression stage into communication; a pressure equalizing tube that causes a gas to circulate from the first space toward the second space; and an oil separating device that separates, in the second space, the lubricating oil contained in the gas. |
