Analysis of Problems and Causes in the Operation of Screw Pump Oil Extraction Te

Screw pump is a rotary pump that relies on the volume change and movement of the meshing space formed between the pump body and the screw to transport liquid or increase its pressure. It can be divided into surface drive and underground drive according to the driving form, and can be divided into single screw pump, twin-screw pump, three screw pump, and five screw pump according to the number of screws. As a new type of machinery for transporting liquids, it is of great significance for the extraction of petroleum. However, there are also many problems in the actual operation of screw pump oil production systems, such as rod and tube wear, wear well problems, etc. Therefore, it is necessary to strengthen the improvement of its technology, improve the adoption efficiency, and bring economic benefits.
