"Overcapacity". If this is the most mentioned term in the field of wind power in 2009, then by 2010, "fan quality" has undoubtedly replaced "overcapacity" and become the most popular vocabulary sought after by the media.
After killing the killing
“The radish is not washing the mud soon.†This is a word often spoken by senior wind energy expert Shi Pengfei. The direction of this sentence is precisely the problems behind the rapid growth of the Chinese fan manufacturing industry. People are most concerned about it. Is the quality of the fan.
This year, Huarui, Goldwind, Dongqi, Suslan, CNAC Huiteng... No matter whether domestic giants or overseas companies, whole-machine manufacturing companies or component manufacturers, are tied to the pillar of fan quality. Above, accept the examination of all parties. From the blades, flanges, spindles, to low-voltage ride-through capability, a big question mark was put on.
An industry that has grown by more than 100% per year since 2003, an industry that is enveloped in multi-layered halos such as “new energy, low-carbon environmental protection, and emerging industries†and an industry that bears an important bargaining chip in climate negotiations should stand this way. Questioning.
However, behind the questioning, we should even think about what kind of industry is this? Is it right for the industry to kill after it is held? the answer is negative.
Vestas former product manager Xue Yijing once made an interesting comparison between the wind turbine and the car: According to a year's operation of 8000 hours, a car will run 400,000 kilometers, but the premise is that every 5000-7000 kilometers need a maintenance. For a high-quality fan, only two regular maintenances are required so that it can continue to operate for 20 years. He concluded that: Compared with automobiles, the design and manufacturing process of wind turbines can be compared with aircrafts and spacecrafts.
Imagine that in the automotive industry that has been developing for more than 100 years, the "recall door" has been repeatedly staged, and the wind power industry is an industry that has been developing in China for more than 10 years. Some problems with the quality of wind turbines are not a matter of design. Should be given a more tolerant attitude, with a rational perspective to examine the inherent problems of the development of the industry?
More tolerance and care
According to Li Junfeng, deputy director of the Energy Research Institute of the National Development and Reform Commission, China's wind power industry is still young and the industrial chain is still immature. It needs to be improved and improved. Some quality problems arise in the process of growth, which is in line with objective laws. Pay attention to solve the problems that have already occurred quickly, gradually improve the quality, reduce the failure rate, and increase the efficiency and efficiency of power generation.
At the same time, society must also tolerate and care for this, and does not want to pursue a certain company or companies. While seeing the quality problems of the wind power industry, we should also see the achievements of the wind power industry.
From the wind power concession tendering in 2003, domestic batch blower manufacturing has gone through 5 years. It can be foreseen that as the number and age of serviced fans increase year by year, the frequency of quality problems in future wind turbines will become higher and higher. The manufacturing industry will gradually transition from the booming adolescence to the quality-oriented adulthood.
At this stage, as far as the industry is concerned, it is necessary to further improve the quality standards of the wind power industry and improve the quality management system in all aspects of the wind power industry. As far as companies are concerned, it is necessary to strengthen the quality assurance system in the production and manufacturing sectors and improve the professional skills of production, installation, operation, and maintenance personnel.
Five years ago, China's wind turbine manufacturing industry had almost no position in the world. After more than five years of efforts, China's wind power equipment manufacturing industry has become one of the most competitive industries with international competitiveness. It has formed a number of important brands and some enterprises. Enter the top 10 in the world. The quality of equipment has also been continuously improved, and the gap with the international advanced level has continuously narrowed.
Summarizing the remarkable achievements made by the wind power industry in these years, it is not difficult for people to find that, besides strong support from the relevant state departments in terms of policies, several major machine manufacturing enterprises have also maintained the industry for many years. After all, in today's society, people pay attention to the quality of wind turbines. The wind power industry should also work together to help the dairy industry.
