Most of the key components are subject to pumps in man-made nuclear plants, which are key components and account for nearly a quarter of equipment investments. Due to the fact that China is not yet fully self-made, foreign companies have gained a large amount of monopoly profits. This reporter has learned that the Ling Ao Phase II nuclear power plant only imported valves amounted to 70 million US dollars, less than 4% of domestic purchases. Nuclear power construction a large number of imported key components of the country is far more than the valve products. According to Zhang Guobao, deputy director of the National Development and Reform Commission recently revealed that he had visited China's nuclear power company, the proposed use of domestic control system, but to put it, "no one dared to use the country." In a recent interview, Cai Weici, vice chairman of China Machinery Industry Federation, briefed reporters on the situation of the key parts and materials under other major technical equipment fields being controlled by others. "Our annual production of power generation equipment has exceeded 100 million kilowatts, but in fact the power generation equipment used inside the high temperature, high pressure pipe imports are still quite large, although the output of our power generation equipment from the past more than 10 million kilowatts Jumped to the present more than 100 million kilowatts, but a closer look, supercritical and ultra-supercritical unit of high temperature, high pressure high-quality pipe, plate, must be imported. "" The mill is now done in China .But though it is domestic Assembly, which a lot of electrical components, or control system, it is imported. "" EHV, UHV power transmission equipment, domestic enterprises also have results, but inside the operating agencies, users of domestic products are not particularly assured, Therefore, it is required that the operation of our operating agency must be co-operated with foreign countries or simply used abroad. "" Transformers are made, but users like the bushings in UHV transformers are not assured. "Although some equipment manufacturers claim they can Do, but users can not cast a vote of confidence. "" The machine tool industry features and numbers System development lags behind, it has become a bottleneck in the development of CNC machine tool industry, especially the constraints of high-end CNC machine tools supporting the critical level of features and numerical control systems, development is slow. "CaiWeiCi consecutive to reporters cited the current situation in the field of five. The words of Zhang Guobao also confirmed Cai Weici's remark: "Although some products have achieved domestic manufacturing, they lack the capability of independent design and manufacturing and do not have the core technology. For most equipment products, although most domestic equipment has basically achieved autonomy, it is reliable In fact, according to the reporter, such as large pumped storage units and heavy-duty gas turbines, domestic enterprises do not have the core technology. Another part of the product development is still blank, such as deep-water offshore oil engineering equipment products, large-scale civilian aircraft. The confidence of the industry to solve the major components of the key components of the issue of autonomy, not by power overnight. Tsai said that rejuvenation is a gradual process, not a mutation. "Like the supercritical units and ultra-supercritical units, the original we can not do the machine, you must import. Now imported from the machine into only part of the import, including raw materials and accessories. For example, pipe, sheet, forgings, is Imported, but this is always a big step forward than the original machine import. "" Like transformers, in the past we can not do 500,000 volt transformer, can do now, although the proportion of domestic products is still small, but We can do it after all. There will also be a gradual increase in market share. The casing inside the transformer is now imported, but this situation has to be broken in the past few years. This is also a gradual process. "Cai Wei Ci Said that the key components and parts of various major equipment is the common problem, but in different areas, different equipment, the performance of different degrees. "Relatively speaking, the power generation equipment is better and the power transmission and transformation equipment is almost the same. The large-scale ethylene plant and nuclear power equipment are even worse." Although the major domestic technological equipment is stuck on the key components and components, Tsai is optimistic about the revitalization of China's equipment industry. "Our goal is that under normal circumstances, we can carry out global support, and if there are signs of trouble, we will not get stuck." China's equipment industry is moving toward the established goal. According to Cai Weizi introduction, 600,000 kilowatts thermal power units of domestic control system, in 2006 has been successfully put into operation in the domestic power plant performance, but also received a dozen sets of orders. Although the proportion of the market in China's 70-80 markets is not large, it is not impossible to import non-non-domestic products. "As for the forging, although the power station is basically imported forgings, but domestic enterprises can not not do it." Tsai Wei Ci said. It is not advisable to pick up some of the key components that could have been produced domestically but are still being imported in large quantities. For example, Cai Wei Ci referred to the power generation equipment forgings, most are imported. According to Cai Wei Ci analysis, this is a domestic enterprises are unwilling to do, not not to do. "Heavy machine factory is now rosy across the board, not a heavy machine factory days are not good. Our heavy machine factory in the case of choice, more inclined to do relatively speaking 'fat' products. Power plant forgings long production cycle, However, Tsai cautions that if the equipment manufacturers are now picky, then in the future once there is a decline in production orders, the lack of technical reserve enterprises, not established in the user The contradiction between a sufficient degree of credit will be highlighted. Cai Wei Ci said that under the background of greatly reducing the foreign exchange surplus, the high-end equipment market will surely face greater squeeze from the imported "All-Star Team" imported products, and the high-end equipment market of domestic-funded enterprises will inevitably be seriously threatened. Therefore, he emphasized that the more we are in a situation of good development in the industry, the more we must enhance the awareness of the crisis and take precautions.
