I. The current situation of general machinery manufacturing industry: Focus on the general status, capabilities and international current competitiveness of the general machinery equipment manufacturing industry; the impact of the financial crisis on the industry, and existing problems and contradictions within the industry.
(I) Position and Capability of General Machinery Manufacturing Industry in the National Economy General machinery is an important part of the equipment manufacturing industry and plays a very important role in the construction of the national economy. It is responsible for providing petroleum, chemical and petrochemical industries. The system is equipped with a complete set of technical equipment, and it also provides auxiliary machines for the power, metallurgy, marine, military, light industry, textile, and pharmaceutical industries. General machinery involves compressors, fans, pumps, valves, air separation devices, separation machinery, drying equipment, gas purification equipment, vacuum equipment, variable speed reducers and various special equipment. Its technical level determines chemical, petrochemical, power, metallurgy , Ship, military, light industry, textile, pharmaceutical and other industries.
In order to adapt to the development of China's petrochemical, electric power, metallurgy and other industries, general machinery and equipment manufacturing enterprises are guided by market demand and target major technical equipment. They have achieved a series of major technical equipment research results through independent innovation and the introduction, digestion, absorption, and integration of innovation. , Basically meet the needs of various sectors of the national economy for general machinery products. Such as large-scale air separation units, ethylene "three machines", chemical process pumps, power station pumps, process gas compressors, drying equipment, vacuum equipment, separation machinery, various valves, speed reducers, etc., have effectively promoted China's petrochemical and electric power Localization of major equipment such as metallurgy and metallurgy. At the same time, it has also promoted the general development of the general machinery and equipment manufacturing industry and the adjustment of product structure, which has improved the overall level of the industry. Driven by the localization of major technical equipment, a number of large general machinery and equipment manufacturing enterprises with strong development capabilities, complete processing methods, and high manufacturing technology have been formed. Shenyang Blower Group Co., Ltd., Shaanxi Blower Group Co., Ltd., Shanghai Blower Co., Ltd., Hangzhou Oxygen Making Co., Ltd., Sichuan Air Separation Co., Ltd., Kaifeng Air Separation Co., Ltd., Shanghai Electric Group Compressor Pump Company, Wuxi Compressor Co., Ltd., Changsha Water Pump Co., Ltd., and Dana Pump Industry Co., Ltd. Company, Suzhou High Pressure Valve Co., Ltd., Zigong High and Medium Pressure Valve Co., Ltd., Chongqing General Machinery Co., Ltd., etc. The production scale, processing equipment, and design capabilities of China's general machinery and equipment backbone enterprises are at the international advanced level. At the same time, some private enterprises, joint ventures and foreign-funded enterprises, such as Shanghai Kaiquan Pumps (Group) Co., Ltd., Shanghai KSB Pumps Co., Ltd., Zhejiang Jialite Liaoyuan Pumps Co., Ltd., Dalian Sulzer Pumps and Compressors, Sichuan Chengfeng Valve Co., Ltd., Shanghai Jialishi Machinery Co., Ltd., Shanghai Feihe Machinery Co., Ltd., Zhejiang Kaishan Machinery Co., Ltd., etc., with their advanced concepts, mechanisms and technologies, have also promoted the independent innovation and localization of China's general machinery and equipment. It played an important role.
With the strong support and cooperation of user departments, China's general machinery manufacturing industry has continuously strengthened its ability to undertake major national technical equipment, and the proportion of domestic equipment has continued to increase. The design and manufacturing capabilities of some major equipment have reached international advanced levels.
The localization rate of refining equipment with an annual output of 10 million tons has reached more than 85%. The localization rate of equipment for the reconstruction and expansion of 450,000-700,000 tons / year ethylene has reached more than 60%. The domestic production rate of 300,000 tons / year of synthetic ammonia and 520,000 tons / year of urea plant equipment has reached over 90%. The localization rate of 40,000 to 60,000 cubic meters of air separation plant complete equipment has reached more than 90%. The localization rate of general machinery auxiliary equipment in 600,000 kilowatt supercritical generating units is over 65%. The localization rate of general machinery in key projects such as metallurgy and environmental protection has reached 90%. The localization ratio of million tons of ethylene, million kilowatt ultra-supercritical units, general machinery auxiliary equipment for million kilowatt nuclear power units, and general machinery complete sets in coal-to-liquid plants is also not increasing, which has been greatly reduced. This has changed China's dependence on foreign equipment and changed the situation of China's long-term introduction of complete sets of technology and equipment.
Ethylene "three machines". Cracking gas, ethylene, and propylene compressors are key equipment for millions of tons of ethylene and have long relied on imports. Since the 1990s, Shengu Group has successfully provided ethylene “three machines” for large-scale ethylene reconstruction and expansion projects such as Daqing, Jinshan, Yangzi, and Maoming through independent research and cooperation with foreign manufacturers. Accumulated experience in the complete set has laid the foundation for the development of the "three machines" of one million tons of ethylene. After repeated demonstrations, Shengu Group has clearly provided a propylene, cracked gas and ethylene compressor to Zhenhai, Tianjin and Fushun respectively. It has signed a contract and put it into design and manufacture. The cracked gas compressor provided for Tianjin Petrochemical has been delivered. . This is a major breakthrough in the design and manufacturing level and capabilities of turbo compressors in China.
Wuxi Compressor Co., Ltd. has successfully developed 300,000 tons / year of HDPE for Sinopec Tianjin's 1 million tons / year ethylene based on the successful development of three-row labyrinth sealed compressors for 100,000 tons / year of high density polyethylene (HDPE) equipment. Developed a four-row labyrinth sealed compressor. Large labyrinth sealed compressors are high-end products of reciprocating compressors, which are technically difficult and have high added value. They can compress olefins and other gases and mixed gases. Only a few manufacturers in the world have mastered their key technologies. Products not only have broad application prospects in the petrochemical industry, but also can be widely used in food, medicine, cement, instrumentation and other industrial fields.
Quench oil pumps, quench water pumps, small flow chemical process pumps, high-precision metering pumps, canned pumps, hydrogenation feed pumps, cryogenic pumps, safety valves, regulating valves, high temperature valves, low temperature valves, etc. in ethylene, refining and coal chemical plants Products are not only technically difficult, but also require many special requirements such as corrosion resistance, wear resistance and high temperature and pressure resistance. In the past, they have relied on imports for a long time. In recent years, through the combination of production, teaching and research, a number of products have been developed that can meet the partial needs of millions of tons of ethylene, 10 million tons of refining, coal chemical and other devices.
Nuclear-grade pumps and valves in nuclear power plants, key pumps, valves, and fans used in ultra-supercritical thermal power have also been developed in China, and some products have been put into use.
