The reporter learned from the Shenyang Blower Group on January 4 that a key technology research project for long-distance pipeline compressor model level has achieved a major breakthrough in the Shenyang Blower Group. This new technology breaks down the foreign blockade of China's long-distance pipeline compressor model-level technology and provides a major technical support for the West-East gas transmission, thereby accelerating the pace of domestic production of long-distance pipeline compressors in China and upgrading domestic long-distance pipeline projects. Compressor manufacturing capacity.
In natural gas and other long-distance pipeline projects, the compressor is an extremely critical device, and the model-level system is a specific factor for the manufacture of the centrifugal impeller system in the compressor. It not only determines the flow rate of the impeller system, but also the flow rate, pressure ratio, Frictional flow loss and other key technical indicators, but also determines the size and cost of the compressor, mechanical properties. Before this, only a few countries had this technology. Due to the fact that no model-level system is mastered in China, the compressor is large in size, high in energy consumption, and consumes a large amount of materials. The compressor is small and fails to meet its functional requirements. With a model-level system, compressors can be produced regardless of the specifications. In order to overcome this technology, Shengu Science and Technology personnel made unremitting efforts to first overcome the model-level basic-level coefficients and independently developed seven model-grade basic stages for long-distance pipeline compressors. On this basis, they used quasi-similar cutting calculations, performance analysis, repeated corrections and other technical measures to optimize the model-level serialization design program, completed a large number of performance tests, obtained a lot of reliable data, completed the long-distance pipeline compressor model level Technical research.
The model-level technology developed by the Shenyang Blower Group is advanced. The PCL series of long-distance pipeline compressors includes 11 model grades with a flow coefficient range of 0.090 to 0.038, which can meet the need for the development of new products for long-distance pipeline compressors in the near future. Its series of model-level efficiency, whether it is a vaneless diffuser or vane diffuser grade, has reached the current world advanced level. The class-head energy coefficient they developed is designed to meet the special requirements of pipeline compressors.
Compressors are widely used in various fields of national economy such as petroleum, chemical industry, natural gas transportation, metallurgy, and air separation, and they are the core equipment of the National Basic Industry and Major Engineering Complete Plants. Compressors play a special role in long-distance pipeline installations and are currently being developed toward large-scale, serialization, high-efficiency operations, miniaturization of structures, and low noise, all of which depend on the core of compressor manufacturing technology—models. Grade factor. Determining the model-level coefficients is not only a key technology for compressor design, but also an important indicator of a country's compressor development level and capabilities.
