market development
The future development trend and direction of the wind turbine are analyzed as follows:
Fan is mainly used in metallurgy, petrochemical, electric power, urban rail transit, textiles, ships and other fields of the national economy and various places of ventilation. In addition to the traditional application areas, in the comprehensive utilization of coal gangue, new dry process clinker, metallurgical industry, energy saving and comprehensive utilization of resources and other more than and 20 potential market areas will still have a greater development prospects.
With the wind turbine manufacturing industry increasingly fierce competition between enterprises, mergers and acquisitions and capital operation has become increasingly frequent in large wind turbine manufacturing, fan of outstanding domestic manufacturing enterprises more and more attention to the research on the industry market, especially the research on industry development environment and product buyers. Because of this, a large number of outstanding domestic fan brand rise rapidly, gradually become a leader in fan manufacturing industry!
The prediction for the use of a wide range of small and medium sized fan fan from the demand characteristics, product structure and manufacturing process is relatively simple, the cost is relatively low, the main user is the pursuit of high efficiency, low noise, long life, and the price is cheap. The other is a capital and technology intensive products, complex structure, long manufacturing cycle, complete and systematic is also strong, but running in high pressure, high temperature and high speed conditions, some even in the harsh conditions of operation, users have different requirements on the fan. On the turbine blower and compressor and large fan, the user is mainly in the pursuit of high quality, high reliability, stable operation and long cycle.
Prediction of general ventilation fan from the main areas of demand structure (usually in small centrifugal and axial flow fan) is the most widely used, the largest demand, most manufacturers. Generally speaking, this kind of product is more than demand. Special purpose fan (including anti-corrosion fan, high temperature fan, wear-resistant fan, exhaust fan fire etc.) demand is not great, but because of special operation conditions, need to be treated differently, because the main material is special. The biggest characteristic of Roots blower is when pressure within the allowable range of regulation, flow pressure change little, a wide range of options, with forced gas characteristics, the main disadvantage is that noise. Through the introduction of technology, joint ventures and self development, our country has launched the blowers with low noise, popular with users, better market prospects. Turbine compressor (including centrifugal compressor, axial flow compressor and axial flow centrifugal compound compressor) is an important equipment of complete sets of equipment, and plays an important role in the national economy. The performance requirements of the turbine compressor both high pressure, but also large flow. With the large scale of the whole plant, the parameters of the turbine compressor are getting higher and higher. Such as blast furnace smelting plant, large-scale coal chemical plant, large scale chemical fertilizer plant, large ethylene plant, large air separation unit, natural gas pipeline transportation device and oil field gas injection device, etc.. The demand for this type of product is very small, but because of its importance, and its complex structure, long manufacturing cycle, high technical content, so it has good economic and social benefits. Turbine compressor manufacturing level represents the overall level of the fan industry. market environment
From the domestic market capacity forecast fan according to different pressure and flow rate, the difference is very big. Therefore, the fan demand should be different according to their type, size, according to the different needs of the industry to predict. According to incomplete statistics, the national wind turbine output from 1980 to 1996, an average annual growth rate of 13.8%. Expected in 2005 the total output of the national wind in between 2 million 600 thousand to 2 million 900 thousand units, in 2010 will reach 3 million 250 thousand to 3 million 100 thousand units. According to the fan industry statistics, prediction of centrifugal compressor output in 2005 was 1 million 600 thousand ~ 1 million 800 thousand, 2010 will reach 2 million to 2 million 100 thousand; 2005 axial compressor production was 260 thousand units in 2010 is expected to reach 360 thousand units; turbine compressor and blower in 2005 the market share of up to 70% the left and right.
From the foreign market forecast China General Machinery Industry Association member units in 2000 exports of 7969 units, the export delivery value of 81 million 157 thousand yuan. From 1991 to 2000 export fan total number of 72876 units, the export delivery value of 747 million 260 thousand yuan.
The trend of the global economic integration is becoming more and more obvious. The economy of each country will depend on each other, the international economic cooperation and exchanges become more and more closely. At the same time, the global industrial restructuring is accelerating the pace of international division of labor, the scale and depth have significant progress, the developed countries will continue to industrial production to capital intensive and technology intensive industries and labor-intensive products transfer to developing countries and regions. This is our country to play its own advantages, among the international market provides a good opportunity for development.
From 1970s, the introduction of advanced technology of centrifugal compressor in China, through digestion and absorption and innovation, improve the grade of products. As long as the guarantee of quality and delivery time, the use of price advantage, in the international competitive. Especially after China's entry into WTO, it is possible to increase the export of the fans. From the historical analysis, the main export varieties are small and medium-sized fan and fan parts. Domestic production of this type of wind turbine, the main gap is the surface quality of the export requirements, if the quality of the appearance, but also has a price advantage in foreign markets, the prospects are broad. From 1991 to 2000, the export situation of the fan, the small and medium-sized fan export is not stable, there is no obvious growth trend. But as the technology continues to progress, it is expected that this type of fan exports will continue to increase, forecast in 2000 will be based on an average annual rate of about 5%.
