Title:
FEED-THROUGH AND BUSHING
Document Type and Number:
WIPO Patent Application WO/2007/141853
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a feed-through for feeding electric power to a submerged
pump installed in a tank for cryogenic liquefied gases such as LNG and LPG. The
feed-through has a simple structure and can check for leakage of the gases and
air at low cost. [MEANS FOR SOLVING THE PROBLEMS] In the feed-through (50), a
bushing (16) made of an insulating material is inserted in the bushing insertion
hole (14) of a flange (12), and a conductor (18) is inserted in the hollow part of
the bushing. A gap between the flange and each end of the bushing insertion hole
and a gap between each end of the bushing and the conductor are sealed airtight
by seal members (20, 22, 24, 26). A through-hole (52) is formed in the wall of the
bushing, and a space part (54) communicating with the through-hole is formed
in the flange. The pressure in the space part of the flange is detected by a pressure
detector (56).
