HYDRAULIC UNIT FOR MECHANICAL PUMPING (HUMP) FOR OIL LIFTING

Abstract: a equipment including a cylinder and a main piston, a pressure accumulator with auxiliary nitrogen tubes for the upward movement of the main piston, an hydraulic unit including an hydraulic fluid deposit and a heat exchanger, an electric or thermal motor for making the hydraulic bomb to work which is responsible of the downward movement of the main piston, responsible for the descending movement of the main piston, diverter valves, closing valves and position, temperature and pressure detectors. the ascent speed can be high, while the descent speed will be normal for this equipment but controlled. all this is coordinated by a program incorporated into the plc.
