Turbine oil - Turbineyu (English spelling) turbine oil

Japanese: タービン油 - タービンゆ(英語表記)turbine oil
Turbine oil - Turbineyu (English spelling) turbine oil
A type of lubricant. It is used for bearings in hydroelectric turbines, steam turbines, and marine power turbines for power generation, and has a wide range of applications, including hydraulic oil for low-pressure hydraulic machines and lubrication for reducers. Generally, additive-free turbine oil, which is a highly refined mineral oil that does not contain additives (antioxidant, rust inhibitor, extreme pressure additives), is used in hydroelectric turbines and various industrial equipment and machinery under relatively stable operating conditions. Additive turbine oil, which is highly refined oil with various additives added, has stable durability for long-term repeated use and is used for steam turbines and steam turbines with reducers. In addition, oils with improved heat resistance are used as gas turbine oils, and synthetic gas turbine oils are used especially for aircraft. In recent years, turbine oils are required to have high performance due to the increasing performance of turbines and industrial machines and the stricter operating conditions, so highly refined oils, oils containing additives, and oils made by chemical synthesis have become common.

Japanese:
潤滑油の一種。発電用の水力タービン,蒸気タービン,船舶動力用タービンなどの軸受に利用されるほか,低圧の油圧機械の作動油,減速機の潤滑など用途は広範囲にわたる。一般に高度に精製した鉱油で添加剤 (酸化防止,錆止め,極圧添加剤) を含まない無添加タービン油は水力タービン,工業用各種設備機械など,稼働条件の比較的安定した範囲で利用される。高度精製油に各種添加剤を加えた添加タービン油は,長期間の反復使用に安定した耐久力をもち,蒸気タービン,減速機付蒸気タービンなどに使用される。また耐熱性を高めたものはガスタービン油として利用され,特に航空機を中心として合成系ガスタービン油が使用されている。近年はタービンや工業用機械などの高性能化や稼働条件の激化に伴い,タービン油も高性能を要求されるため,高度精製したものや添加剤を使用したもの,化学合成による油が一般化してきている。
