Title:
INSULATION GAS RECOVERY AND FILLING DEVICE
Document Type and Number:
Japanese Patent JP3706731
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an insulation gas recovery and filling device enabling to excellently recover insulation gas and also superior in portability.
SOLUTION: This device consists of a vacuum pump circuit part A consisting of a water cooling type vacuum pump 15 for sucking insulation gas from an insulation gas-enclosed instrument and feeding it out, a compression circuit part B for compressing the fed-out recovery gas, a liquefying circuit part C for cooling the compressed recovery gas and condensing to liquefy, a storage tank part D for enclosing and storing the liquefied recovery liquid, and a gasification circuit part E for heating and evaporating the recovery liquid fed out from the enclosed storage tank D and feeding it out to the insulation gas- enclosed instrument. These circuit parts A-E are housed in a same casing.
