1. Overview
Pumping machine is a kind of machine equipment for oil exploitation, commonly known as "kowtow machine", which makes oil out of the well by means of pressure. When the pumping unit is on the stroke, the oil pipe elastically contracts and moves upward, driving the mechanical unplugging oil extractor to move upward, and hitting the sliding sleeve to generate vibration; at the same time, the forward check valve is closed, and the reducing piston assembly blocks the oil. When the pumping unit is on the stroke, the elastic elongation of the oil pipe moves downward, driving the mechanical unplugging oil extractor to move downward, and hitting the sliding sleeve to generate vibration; at the same time, the area below the reverse check valve forms a high pressure zone, which in turn produces a reverse impact force on the oil flow path in the formation.
Through the improved new teaching pumping unit, the fuselage structure is simple, the full panel operation, can increase the computer, directly collect the required experimental parameters and draw the indicator diagram.
