HYDRAULIC MECHANICAL PUMPING UNIT COMPRISING A BUILT-IN RADIATOR

摘要

The invention relates to a hydraulic mechanical pumping unit comprising a radiator built into the chassis and a hydraulic circuit that allows operation with high flow rates and low pressure or with low flow rates and high pressure. This hydraulic mechanical pumping unit comprising a built-in radiator is used to supply a determined volume of pressurised hydraulic oil to a hydraulic actuator which, in turn, lifts the load exerted by a rod string and the hydrostatic column inside an oil well. The main characteristic of said hydraulic mechanical pumping unit comprising a built-in radiator is that the radiator forms part of the chassis of the machine and is arranged between two tanks of hydraulic oil. The first of said tanks is the oil suction tank, while the second tank is the oil return tank.
