Abstract

PURPOSE:To easily perform attachment and detachment of secondary seal by remote control and shorten workhours of maintenance and inspection of an internal pump by using a secondary handling fitting having a claw member. CONSTITUTION:A support body 57 equipped with a secondary sealing handling fitting on a base stand 56 is inserted and fixed in a casing 33, an oil pressure mechanism 61 is driven, a secondary sealing handling fitting 60 is lifted and a claw member 62 is passed in the inner circumference of a secondary seal 30. The both side part 62A of a claw member 62 is threadedly engaged with the upper end part of the secondary seal 30 as the claw member 62 is opened. A wedge 65 of a washer handling mechanism 64 is lifted by interlocking there with, a washer 52 is pushed and inserted in the channel part 30A of the secon dary seal 30. In this condition the secondary sealing handling fitting 60 is lowered and the secondary seal 30 is taken out. Therefore, the attachment and detachment of the secondary seal 30 can be performed in a short time without damaging the secondary seal 30, the washer 52 and the near members.
