OIL SUPPLY IN RENEWABLE ENERGY TURBINE GENERATOR |
摘要 |
A renewable energy turbine generator (1), such as a wind turbine generator, comprises a hydraulic pump (20), a hydraulic motor (24) and an oil circuit (26, 28) connecting the hydraulic pump and the hydraulic motor. Oil in the low pressure side (28) of the oil circuit is cooled and supplied to the working chambers (95) of the hydraulic pump. A reduced temperature oil feed provides additionally cooled oil to the bearings of the hydraulic pump and the hydraulic motor. Thus, cooler and more viscous oil is supplied to the bearings (84) of the hydraulic pump and/or hydraulic motor and warmer and less viscous oil is supplied to the working chambers, increasing the efficiency and lifetime of the bearings and of the working portions of the hydraulic pump and motor. |
