DEVICE FOR PROPORTION SUPPLY OF CHEMICAL REAGENT TO WELL Russian patent published in 2001 - IPC

Abstract RU 2171364 C1

FIELD: control of well complications; applicable in oil producing industry. SUBSTANCE: device has proportioner, vessel, pressure line, column of hollow rods, check valve and drive of submersible pump. Proportioner is located on side surface of reducing gear body for motion along body. Proportioner may be made in form of guided-vane pump. Kinematic connection of pump drive with reducing gear shaft is independent in form of V-belt transmission. Pressure line is made in form of rigid hose. Hydraulic communication of hollow rod column and proportioner is effected by converter of motion. Converter consists of two parts-immovable upper and movable lower parts, with movable part executing rotary motion. EFFECT: simplified design, reduced expenditures for well servicing. 4 cl, 1 dwg
