LL-F type Reverse Circulation Junk Basket
Application and Features:
LLF type Reverse Circulation Junk Basket is designed to remove all types of small junk s such as bit cones, cutters and hand tools from the bottom of the well bore.
The tool's main feature is that it eliminates the possibility of pulling a wet string duringfishing operation with its reverse drainage design. The RCJB can also be used as a fish magnet when fitted with a magnet insert, while maintaining its reverse fluid circulatio feature.
Working principle:
Begin circulation of the junk basket to wash the hole. Stop circulation and drop the steel ball. (When the steel ball is dropped into the valve seat, reverse fluid circulation is activated. The fluid travels outward and downward through the inner passage of the barrel and out through the vents in the lower end. The fluid is then deflected to the center of the tool and up through the return holes in the upper end of the barrel.
