Description

Technical Field

[0002] With the sustained and rapid development of my country's national economy, the demand for energy such as oil and wellhead raw gas is increasing. As an important equipment in the process of oil and wellhead raw gas extraction, pressurization, gathering and transportation, production increase, light hydrocarbon recovery, gas injection, oil production, wellhead raw gas storage and liquefaction, the technical level and production capacity of gas boosting equipment must adapt to the needs of energy development. The rapid development of the oil and wellhead raw gas industry requires a variety of compressors with high efficiency, good reliability and wide coverage to meet the various process requirements of oil and gas extraction, gathering, storage and processing. However, there is a large gap between the power range and variety of domestic gas compressors and the demand. The high-speed, high-power split gas boosting equipment widely used in wellhead raw gas boosting and gathering is a typical example of the gap between China and foreign countries. Due to dependence on imports, many disadvantages such as poor after-sales service, difficulty in supplying repair parts, long delivery time and high prices have long restricted the efficient extraction, gathering and processing of domestic oil and wellhead raw gas.

[0003] Traditional compressors cannot meet the requirements of high flow and high pressure. At the same time, due to their size and weight limitations, they are not easy to carry and install. Specifically, traditional compressors have the following technical problems:

[0004] Size and weight limitations: Traditional compressors are usually large and heavy, making them inconvenient to carry and install. This limits their application in some occasions, especially in some scenarios where space is limited or mobile installation is required. Operation efficiency: Traditional compressors have limited operation efficiency under high pressure and high flow requirements due to the limitations of design structure and working principle. This means that in actual applications, greater power and energy consumption may be required, resulting in cost and energy waste.

[0005] Noise and vibration: Traditional compressors generate a lot of noise and vibration when running at high speed, which brings inconvenience and potential safety hazards to the surrounding environment and personnel. This is a problem that cannot be ignored, especially in some occasions that require a quiet environment or are crowded with people. Summary of the invention
