Mechanical hydraulic pumping unit with a radiator integrated

Abstract

The invention corresponds to a mechanical hydraulic pumping unit with a radiator integrated to the chassis and a hydraulic circuit which allows it to operate with high flow rates and low pressure or with low flow rates and high pressure. This mechanical hydraulic pumping unit with a radiator integrated is used to supply a particular pressurized oil flow to a hydraulic actuator, which in turn lifts the load exerted by a string of rods and lift the hydrostatic column that is inside an oil well. The main feature of this mechanical hydraulic pumping unit with a radiator integrated is that the radiator is part of the machine's chassis and is located in the middle of two hydraulic oil tanks. The first of these tanks is the oil suction tank, while the second is the oil return tank.

Claims

1. A hydraulic pumping apparatus comprising: an enclosure with a lower section and an upper section; said upper section of said enclosure comprising: a suction tank coupled at a first end of said enclosure at said upper section; a discharge tank coupled at an opposing end of said enclosure at said upper section; a radiator forming an integral part of said enclosure and coupling the suction tank and the discharge tank; an outlet vent located between the suction tank and the discharge tank and above the radiator; said lower section of said enclosure comprising: a motor comprising a shaft having a front end and a rear end; an inlet vent at the first end of said enclosure; a fan coupled to the rear end of the shaft and configured to suck external air into said enclosure through said inlet vent; a dual pump unit coupled to the front end of the shaft of the motor, wherein the dual pump unit comprises a single suction fluidly coupled to the suction tank via a ball valve, wherein the dual pump unit comprises a primary pump and a secondary pump, wherein the primary pump's output is fluidly coupled to a flow connector and the secondary pump's output is fluidly coupled to a selector valve, wherein the selector valve is configured to selectively direct flow from said secondary pump to either the flow connector thereby summing the primary pump's output with the secondary pump's output or to the discharge tank; and a hydraulic power circuit coupled to the flow connector.
