  • 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.
