Description

Technical Field

[0001] This utility model relates to a novel oil pump for refueling petroleum oil drums in bulk, and belongs to the field of oil pump technology. Background Technology

[0002] A pumping pump is a common downhole device that uses a pumping unit to pump crude oil from a well to the surface. A typical pumping pump mainly consists of four parts: the pump barrel, the suction valve, the piston, and the discharge valve. According to the way the pumping pump is fixed downhole, it can be divided into tubular pumps and rod pumps. Tubular pumps have a simple structure and low cost, while rod pumps have a complex structure and high manufacturing cost and are suitable for oil wells with a large pumping depth.

[0003] Existing oil pumps all have a fixed power source design. When the power source fails, the entire pump head is rendered unusable. The integrated design also results in high maintenance costs, which cannot meet people's needs. Utility Model Content
