Fans future trends and directions

　　Fans include fan, turbine blowers, blower and turbine compressors, including a detailed breakdown of centrifugal compressors, axial compressors, centrifugal blowers, blower, centrifugal fan, axial fan Yip blowers and 7 categories. Fans future trends and directions as follows:

　　From fans to predict demand characteristics for the use of a wide range of large medium and small fan, the product structure and manufacturing process is relatively simple, low cost, users are mainly the pursuit of high efficiency, low noise, long life, and low prices. Another is the capital and technology intensive, complex product structure, long manufacturing cycle, complete and systematic also strong, and operated under high pressure, high temperature and high speed conditions, and some even run in harsh conditions, users of the class fans have different requirements. For turbo blowers and compressors and large fan, users are mainly the pursuit of high quality, high reliability, smooth operation and long life cycle. Waterproof fan

　　Predict general ventilation fan from the main areas of demand structure (typically for small and medium centrifugal and axial flow fan) the most widely used, the most in demand, manufacturers are up. Overall speaking, this kind of product oversupply. Special purpose fans (including anti-corrosion fan, heat fan, wear fan, exhaust fan fire, etc.) demand, while not great, but the special operating environment, require separate treatment, because the main material requirements more special. Roots blower is the most important feature within the allowable range when the pressure regulator, the flow rate has changed little, a wide pressure range of options, with forced gas transmission characteristics, the main drawback is noisy. In recent years, through the introduction of technology, joint ventures and its own development, China has launched a low noise Lobe Roots Blower, popular with consumers, the market outlook is good. Turbine compressor (including centrifugal compressors, axial compressor and axial - centrifugal compressor complex) is a major engineering complete sets of equipment important equipment, plays an important role in the national economy. Performance requirements for turbine compressor both high pressure, but also large flow. With large-scale sets of devices requiring increasing turbine compressor parameters. Such as blast furnace smelting equipment, large-scale coal chemical plant, a large fertilizer plant, large-scale ethylene plant, large air separation plants, natural gas and oil pipeline to transport gas injection system devices. Fans of the total demand for such products accounted for very little, but important, as well as the structure of complex, long manufacturing cycle, high technology, and therefore, there is relatively good economic and social benefits. Turbine compressor manufacturing level represents the overall level of the fan industry. From the domestic market capacity forecast fan pressure and flow depending on the requirements, very different. Therefore, fans should demand their type, size distinction, according to the forecast demand in different sectors. According to incomplete statistics, fan output from 1980 to 1996, an average annual growth rate of 13.8%. 2005 China is expected to total between 2.6 million fans to 290 million units in 2010 will reach 3.1 million to 325 million units. Fans of the industry over the years according to statistics, forecasts annual production of centrifugal compressor 2005 1.6 million to 180 million units in 2010 will reach 2 million to 210 million units; axial compressor 2005 production of 260,000 units, is expected to reach 360,000 in 2010 turbine compressors and blowers in 2005 the market share of up to about 70%; Taiwan.

　　From foreign markets predict China General Machinery Industry Association Fan outlet fan 7969 units in 2000, the export delivery value of 81.157 million yuan. 1991 to 2000 the total number of units for export fan 72876 units, export delivery value of 747.26 million yuan.

　　At present, more and more obvious trend of economic globalization, interdependence of national economies will further international economic cooperation and exchanges between the increasingly close international market in a significant crossover and integration phase. Meanwhile, the global industry is accelerating the pace of structural adjustment, the size and depth of the international division of labor are major progress in the developed world industrial production to capital-intensive and technology-intensive industries, labor-intensive products to developing countries and regions. This is for our country to play their own advantages, among the international market provides a good opportunity for development.Cooling fan

　　From the 1970s, the country began to introduce foreign advanced technology centrifugal compressor, after digestion and absorption and innovation, improved product quality. Just make sure the quality and delivery, using the price advantage in the international arena is competitive. Especially after China's accession to WTO, increasing the blower outlet is entirely possible. From a historical analysis, the main export variety is small fan and fan accessories. Domestic production of such fans of enterprises, the main difference is not up to the surface quality of the export requirements, if improving the appearance of quality, but also has a price advantage in foreign markets prospects are bright. From 1991 to 2000 the export situation fan, small fan export is not stable enough, there is no clear growth trend. But as technology advances, expect that these fans will continue to increase exports, forecast in 2000 will be based on the average annual rate of about 5 percent annually.

　　Centrifugal compressors and blowers from 1991 to 2000 have a more significant increase in exports in 2000 reached 87 units. The main exporting countries are India, Pakistan, Iran, Vietnam and other developing countries. Expected that this trend will develop up to 100 units per year.
