Chemicals out the pump exit
During this period of energy shortage, chemical means are commonly used to increase the flow of hydrocarbons from a production well. Such chemicals are normally pumped down a well to reduce the resistance of flow from the surrounding strata into the well.Forged Steel Valves Various chemical pumps or injectors have been devised, including some for use with a "walking beam" type production pump. Such prior devices have not only been bulky, but have required placement in inconvenient locations. The pump of this invention is not only compact and efficient, but may be positioned in any number of locations of convenience.
SUMMARY OF THE INVENTION
An actuator beam is pivotally joined to the walking beam of a production pump. Said actuator beam pivots about a fixed pivot joint and one end of the actuator beam causes reciprocation of a plunger rod within the chemical pump body. Balance ValvesAn outside chemical source would make treating chemicals available at the pump inlet. The upward plunger stroke creates a partial vacuum within the pump body and draws chemicals therein. The downward stroke forces such chemicals out the pump exit, against the force of a spring biased ball check valve, through a conduit into a well. REDUCING VALVESThe linkage between the actuator beam and the pump housing is such that while relative vertical movement between the actuator beam pivot point and the housing is restricted, there may be relative rotational movement.
