FLEXIBLE TWIN-CONTAINER FOR OIL CHANGE

For oil change in a gearbox of a wind turbine (19), a flexible, collapsible oil tank (1) is provided with an upper chamber (2) for receiving the used oil from the gearbox and a lower chamber (3) for providing clean oil. After draining the used oil from the gearbox into the upper chamber (2) of the o...

Zusammenfassung:	For oil change in a gearbox of a wind turbine (19), a flexible, collapsible oil tank (1) is provided with an upper chamber (2) for receiving the used oil from the gearbox and a lower chamber (3) for providing clean oil. After draining the used oil from the gearbox into the upper chamber (2) of the oil tank (1) and during the process of filling new oil into the gearbox from the lower chamber (3) of the oil tank (1), the weight of the used oil in the upper chamber (2) presses the clean oil out of the lower chamber (3) which minimizes the risk for cavitation of the pumping unit (24) that is used to pump the new oil up into the gearbox in the nacelle. For offshore wind turbines (19), the oil tank (1, 1') is brought by a sea vessel (21) to the wind turbine (19) and fetched again after oil change. Optionally, the necessary pumping unit (24) and pipes (27) are also brought and fetched again by the vessel (21).
