Product Reverse Circulation Junk Basket - China

price: contact company for price

TIANHE Reverse Circulation Junk Basket (RCJB) is designed to

remove all types of small junk objects from the hole. The

tool's main feature eliminates pulling a wet string. Even

when the tool is fitted with a magnet insert, reverse

circulation is maintained.

Operation

TIANHE RCJB is made up to the bottom of the fishing string

and lowered to a point within several feet from the bottom

of the hole. Begin circulation to wash the hole. Stop

circulation and drop the steel ball. (When the steel ball is

dropped into the valve seat, circulation 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. This reverse

fluid circulation carries the junk into the barrel above the

junk catcher.) Begin circulation again, slowly rotating

while lowering the tool until a 10-inch core has been cut.

Stop rotation and circulation and pull the tool from the

hole.
