LL-F Type Reverse Circulating Junk Basket

LLF type reverse circulating junk basket drillingis designed to remove all types of small junks such as bit cones, cutters and hand tools from the bottom of the wellbore.

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.
