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 exceeds 85% self-sufficiency, passive situation that China's advanced equipment mainly relying on imports 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.

Force to make up the short board

Although the quality brands of machinery industry in our country have made great improvement at present, overall the quality of mechanical products in our country still lags behind that of industrialized countries, mainly in the areas of weak R & D capability, unreasonable product structure, independent brands Missing and so on. "China's gear industry research and development cycle of new products is similar to foreign products 2 to 3 times the contribution rate of new products for foreign one-tenth of the overall technical level behind 6 to 10 years." Wang Ruixiang pointed out that China's machinery industry's independent research and development Weak ability, the overall level of lag. At present, the majority of industrial enterprises accounted for less than 3% of R & D investment, while others only accounted for 1.2%, lagging far behind leading international companies. Enterprises in the quality and safety, common technology and other aspects of a serious lack of input, independent innovation ability gap significantly.

Insufficient high-end products, low-end products, excess product structure has restricted the development of the industry. At present, the basic mechanical products in our country are mainly middle and low grades. Some products have a large gap between their performance and developed countries and even lag behind the international advanced level in 20 to 30 years. For example, about 80% of the leading products in the pneumatic industry are equivalent to the international standards in the early 1980s and 1990s. Most of the low-voltage electrical products in the power transmission and distribution industry are mainly concentrated in the low-end and the domestic market. About 90% of the large castings and forgings, 95% of high-end CNC system, 80% of the chips and almost all of the high-end hydraulic parts, seals, engines rely on imports. Most high-end products in the field of metal processing and manufacturing are monopolized by foreign countries.

At the same time, product consistency, stability, reliability is poor, lack of own brand. At present, China's overall standard of mechanical products lags behind. Most of the domestic machine tool technology standards are equivalent to foreign standards, there are few custom standards. Involving safety and environmental protection of China's automotive mandatory standard system, mainly in Europe ECE regulations / EC Directive as a reference. Nuclear nuclear pump mechanical seal standard is still blank. General high-end areas in the stability of the product lags behind the international advanced level of more than 10 years. Product life is only 30% of similar products abroad 50%. The production process and basic equipment lag behind. The rejection rate is 5% -10% higher than that of developed countries. The comprehensive energy consumption is twice that of industrialized countries and the average motor operating efficiency is 10% ~ 20% lower than that of developed countries. At the same time, few international companies and world famous brands in the machinery industry have international influence. In the international market competition, China's machinery industry is still in the industrial chain, the low-end value chain.

In addition, China's machinery industry in the quality management theory, philosophy and other research and application of relatively backward, uneven development. Insufficient investment in industrial inspection and testing institutions, infrastructure, means a single, and the rules are not perfect, aging professionals, literacy is not high. The gap between on-line measurement of mold processing, computer-aided measurement and business management with the international advanced level is more than 10 years, and the quality assurance ability of small enterprises is generally weaker.
In response, Wang Ruixiang proposed that we should speed up the improvement of the industrial standardization system in light of the lag in the overall industry level, the unreasonable structure and the shortage of emerging industry standards. In view of the issues of consistency, stability, safety and lack of durability of the equipment, , Improve the quality inspection and testing technical support system; in view of the outstanding problems in accreditation and measurement work, speed up the improvement of the accreditation and certification system and strengthen the scientific and technological innovation and application system construction; stimulate enterprises to enhance the endogenous power of quality brands and guide enterprises Promote total quality management, actively encourage enterprises to "go global", participate in the "Belt and Road Initiative", strengthen cooperation in international capacity and equipment manufacturing, foster new advantages in foreign economy with technology, standards, brands, quality and service at its core, and promote the development of the machinery industry As soon as possible into the quality of the times.
