How will the roots blower market develop?

Market development, future fan development trends and direction analysis are as follows:

Fans are 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, there will still be greater development prospects in more than 20 potential market areas such as comprehensive utilization of coal gangue, technological transformation of new dry process clinker, energy saving in metallurgical industry and comprehensive utilization of resources.

With the increasing competition in the fan manufacturing industry, mergers and acquisitions integration and capital operation among large fan manufacturing enterprises are becoming more and more frequent, and the excellent domestic fan manufacturing enterprises pay more and more attention to the research of the industry market, especially the in-depth study of the industrial development environment and product buyers. Because of this, a large number of excellent domestic fan brands have risen rapidly and gradually become the leader in the fan manufacturing industry!

Forecast from the characteristics of fan demand For small and medium-sized fans with a large amount of use, the product structure and manufacturing process are relatively simple, and the cost is also low. Users mainly pursue high efficiency, low noise, long life, and low price. The other is capital-and technology-intensive, with complex product structure, long manufacturing cycle, and strong integrity and systematicness, and it operates under high pressure, high temperature and high speed conditions, and some even operate under harsh working conditions. This type of fan has different requirements. For turbine blowers, compressors and large fans, users mainly pursue high quality, high reliability, stable operation and long cycle.

From the main areas of demand structure prediction General ventilation fans (generally small and medium-sized centrifugal and axial fans) are the most widely used, the largest demand, manufacturers are also the most. Generally speaking, the supply of such products exceeds the demand. Special purpose fans (including anti-corrosion fans, high-temperature fans, wear-resistant fans, fire exhaust fans, etc.) demand is not very large, but due to the special operating environment, need to be treated differently, because the main material requirements are more special. The biggest characteristic of Roots blower is that when the pressure is adjusted within the allowable range, the flow rate changes little, the pressure selection range is wide, and it has the characteristics of forced gas transmission. The main disadvantage is that the noise is large. Through the introduction of technology, joint ventures and self-development, China has launched a low noise three-leaf Roots blower, popular with users, the market prospects are good. Turbine compressors (including centrifugal compressors, axial compressors and axial-centrifugal composite compressors) are important equipment for major engineering installations and play an important role in the national economy. The performance of the turbine compressor requires both high pressure and large flow. With the large-scale of the complete set of equipment, the parameters of the turbine compressor are required to be higher and higher. Such as blast furnace smelting equipment, large coal chemical plant, large fertilizer plant, large ethylene plant, large air separation plant, natural gas pipeline transportation device and oil field gas injection device. The demand for such products accounts for very little of the total fan, but due to the importance, complex structure, long manufacturing cycle and high technical content, it has better 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 requirements, the difference is very big. Therefore, the demand for fans should be distinguished according to their type and size, and predicted according to the demand of different industries. According to incomplete statistics, the national fan output from 1 980 to 1996, the average annual growth rate of 13.8. It is estimated that the total output of wind turbines in the country will be between 2.6 million and 2.9 million in 2005 and will reach 3.1 million to 3.25 million in the 201 year. According to the statistics of the fan industry over the years, it is predicted that the output of centrifugal compressors will be 1.6 million -1.8 million in 2005 and 2 million -2.1 million in 2010. The output of axial flow compressors was 260000 in 2005 and is expected to reach 360000 in 2010. The market share of turbine compressors and blowers in 2005 can reach about 70%.

From the foreign market, it is predicted that the member units of China General Machinery Fan Industry Association will export 7969 sets of fans in 2000, with an export delivery value of 8115.70000 yuan. From 1991 to 2000, the total number of export fans was 72876, and the total export delivery value was 747.26 million yuan.

The trend of global economic integration is becoming more and more obvious, the economies of various countries will become more interdependent, international economic cooperation and exchanges are becoming closer, and the international market is in a stage of substantial intersection and integration. At the same time, the pace of global industrial restructuring is accelerating, and significant progress has been made in the scale and depth of the international division of labor. Developed countries continue to shift industrial production to capital-intensive and technology-intensive industries, and labor-intensive products are shifting to developing countries and regions. This provides a good development opportunity for our country to play its own advantages and enter the international market.

Domestic from the 1970 s began to introduce foreign advanced technology of centrifugal compressor, through digestion, absorption and innovation, improve the product grade. As long as the quality and delivery time are guaranteed, and the price advantage is used, it is competitive in the world. Especially after China's accession to the WTO, it is entirely possible to increase fan exports. From the historical situation analysis, the main export varieties are small and medium-sized fans and fan accessories. Domestic production of this kind of fan enterprises, the main gap is the surface quality can not meet the export requirements, if improve the appearance quality, but also has the price advantage, in the foreign market prospects are broad. From 1991 to 2000, the export of small and medium-sized fans is not stable enough, and there is no obvious growth trend. However, with the continuous advancement of technology, it is expected that the export volume of such fans will continue to increase, and it is predicted that it will increase at an average annual rate of about 5% on the basis of 2000.

The export of centrifugal compressors and blowers increased significantly from 1991 to 2000, reaching 870000 units in 2000. The main exporters are India, Pakistan, Iran, Vietnam and other developing countries. This trend is expected to grow, reaching 1 million units per year.
