OIL-FILLING METHOD, AND OIL-FILLING AND/OR OIL-EXTRACTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an oil-filling method and an oil-filling apparatus capable of preventing effectively generation of static electricity during an oil-filling work. ;SOLUTION: A gas-filling process for filling an inert gas in the specific gravity almost the same as or higher than air into a container through a first nozzle 11, an oil-filling process for inserting a second nozzle 48 and filling oil into the container through the second nozzle 48 and a weighing process for weighing continuously the weight of the filled oil are provided. The second nozzle 48 is gradually raised while the container is being filled with the oil, and when the weight of the oil reaches a specified level, a valve 74 for stopping supply of oil to the second nozzle 48 is closed and an oil passage formed in the second nozzle 48 is closed with an opening/closing valve provided at the second nozzle 48 operated.;COPYRIGHT: (C)1999,JPO
