【摘要】：要提高中国天然气管道建设运营效益,实现管道压缩机组和大口径阀门等关键设备的国产化是基础。为此,中国石油天然气股份有限公司联合国内相关企业,建立了国产化技术研发体系和新产品分级试验体系,并成功开发了20MW级电驱压缩机组、30MW级燃驱压缩机组和高压大口径全焊接球阀:1电驱机组研制围绕三大主体单元组织实施,研发的25MVA单元串联多电平结构变频调速装置在国际同类产品中容量最大,研发的4 800r/min超高速防爆电机功率达22MW,研发的PCL800型离心压缩机工作点效率高、流量调节范围宽;2燃驱机组研制分两步走,围绕进口GT25000燃气轮机开发辅助配套系统和电控系统,配套国产压缩机形成产品一,同时开展燃气轮机自主研发,替换进口燃气轮机,形成产品二;3围绕焊接和密封两项技术难点开展攻关,开发的40英寸Class600、48英寸Class600和48英寸Class900三种规格两站安装方式的高压大口径全焊接球阀已全面替代进口产品。结论认为,压缩机组和阀门的成功国产化带动了装备制造行业、天然气行业产业链的良性发展,对于推动企业自主创新、提升企业核心竞争力、促进产业转型升级等方面都具有重大意义和作用。
[Abstract]:In order to improve the efficiency of natural gas pipeline construction in China, it is essential to realize the localization of key equipment such as pipeline compressor unit and large-caliber valve. To this end, the China National Petroleum Corporation, in conjunction with relevant domestic enterprises, has established a domestic technology research and development system and a new product classification test system. The 20MW class electric drive compressor unit and the high pressure large-caliber all-welded ball valve No. 1 electric drive unit have been successfully developed and implemented around the three main units. The 25MVA unit series multilevel variable-frequency speed regulating device has the largest capacity in the international products of the same kind, the 4 800r/min super-high speed explosion-proof motor power is 22MW, and the developed PCL800 centrifugal compressor has high working point efficiency. The development of a wide range of flow regulation 2 fuel drive units is divided into two steps. Around the imported GT25000 gas turbine development auxiliary supporting system and electronic control system, the domestic compressor forms a product, and at the same time, the independent development of the gas turbine is carried out to replace the imported gas turbine. In order to solve the key problems around the two technical difficulties of welding and sealing, the high pressure large-caliber full-welded ball valve with 40 "Class600-48-inch Class600 and 48-inch Class900 has completely replaced the imported products. The conclusion is that the successful localization of compressor units and valves has driven the equipment manufacturing industry and the natural gas industry chain to promote independent innovation and enhance the core competitiveness of enterprises. Promotion of industrial transformation and upgrading are of great significance and role.
