Beam Pumping Unit – 3D Model SolidWorks
The oil pump is a kind of machine equipment for oil extraction, commonly known as “kowtow machine”, which uses pressure to make oil come out of the well. When the oil pump is in the upstroke, the oil pipe elastically contracts and moves upward, driving the mechanical unblocking oil extraction device to move upward, hitting the sliding sleeve to generate vibration; at the same time, the forward check valve is closed, and the variable piston assembly blocks the oil. When the oil pump is in the downstroke, the oil pipe elastically extends and moves downward, driving the mechanical unblocking oil extraction device to move downward, hitting the sliding sleeve to generate vibration; at the same time, the reverse check valve is partially closed, and the variable piston assembly still blocks the annular oil channel of the oil casing, so that the area below the reverse check valve forms a high-pressure area, and this movement generates a reverse impact force on the oil flow channel in the formation.
