At present, the major technical performance indicators of UHV transformer independently developed by our country have reached the international advanced level as a whole. The UHV converter transformer has been domestically manufactured. The traction transformer for the railway has been successfully domestically produced and has completely replaced the import. Machine tools and some
high-end products have broken the international monopoly; high-precision, extra large bearings replace imported products, to fill the gaps in the domestic market ... ... "At present, China's machinery market in the domestic market has more than 85% self-sufficiency, China's advanced equipment mainly rely on imports Passive situation began to change. "China Machinery Industry Federation Wang Ruixiang recently said in Beijing, with the recent years, China's machinery industry quality brand building continue to make new achievements, including major technical equipment, including the localization rate, the domestic market The proportion continues to increase.
Quality has improved
In the quality of the brand upgrade process, industry and enterprises focus on the development of new varieties, the application of new technologies, product self-sufficiency rate continues to increase. At present, China's agricultural combine harvester has fully met the domestic demand, car crankshaft and other key parts and components processing equipment 80% to meet user needs, car engine cylinder head cylinder semi-finishing equipment to achieve the group line applications, machinery and equipment on the national economy focus Increasing support for the field.
International standards of quality standards, product reliability, consistency and continuously improve. According to statistics, at present, the average passing rate of mechanical products in our country has basically remained above 90%, an increase of nearly 4 percentage points over the last 12th Five-year Plan period. Key areas of power equipment technology and product yield has entered the world, the effective coefficient remained above 95%. The mean time between failure (MTBF) of CNC system independently developed by the basic machinery has reached more than 25,000 hours, and the average MTBF of the whole machine has reached more than 1,200 hours. The CNC system keeps close to the advanced countries in the world and begins to enter mass market. The tractor manufacturing industry has developed its own development and design capabilities that cover power levels below 200 kW. Enterprises adopt advanced production and product standards, the international standard adoption rate increased significantly. At present, the key quality indicators such as the quality and reliability of the key products in the industry have reached the international advanced level. In 2016, there were 133 national standards and the standards were translated into international standards. Dozens of this year were included in the plan.
Since the 12th FYP, 188 high-quality products have won the title of "China Machinery Industry Quality Brand" and 58 enterprises have won the title of "National Industry Brand Cultivation Demonstration Enterprise", and 40 have been identified Industrial agglomeration regional brands, of which 3 became the first industrial cluster regional brand building demonstration area. Some autonomous products such as automobiles and construction machinery have gone out of the country and marched toward the international market.
