Application of Screw Pumps in the Petroleum Industry
Screw pumps play a vital role in the petroleum industry and are widely used and effective. One of the core tasks of the petroleum industry is to pump crude oil from underground reservoirs to the surface for subsequent processing and treatment. In this process, the screw pump has become an indispensable equipment in the oil extraction and transportation process with its unique advantages.
First, progressive cavity pumps can efficiently pump crude oil from the bottom of the well. Its working principle is to form a continuous sealed chamber through the rotation of the screw and bushing, thereby pushing the crude oil from the suction end to the discharge end. This transportation method not only has stable flow rate, but also has small pressure pulsation, which can ensure the stability and continuity of crude oil during transportation.
Secondly, the screw pump has wide adaptability. In the petroleum industry, crude oil’s viscosity, temperature, and possible impurities and particles present challenges to conveying equipment. However, the screw pump can easily cope with these complex working conditions due to its structural features and material advantages. It can adapt to crude oil of various viscosities and temperatures, and can even transport crude oil containing impurities and particles, thus ensuring the smooth progress of oil extraction and transportation.
In addition, screw pumps feature high reliability and long life. Its simple structure, few moving parts, and few wearing parts make the screw pump highly stable and reliable during operation. At the same time, the screw and bushing of the screw pump are in physical contact and wear slowly, so they have a long service life. These characteristics make screw pumps widely used and recognized in the petroleum industry.
In the future development of the petroleum industry, screw pumps will continue to play an important role in providing more reliable and efficient solutions for oil extraction and transportation.
