Analysis on the development trend of small and medium-sized centrifugal and axial flow fans
Fans are mainly used for ventilation and ventilation in various fields of the national economy, such as metallurgy, petrochemicals, electricity, urban rail transit, textiles, and ships. In addition to the traditional application fields, there will still be great development prospects in more than 20 potential market areas, such as comprehensive utilization of coal gangue, technological upgrading of new dry clinker, energy conservation in the metallurgical industry and comprehensive utilization of resources.
As the competition in the wind turbine manufacturing industry continues to intensify, mergers and acquisitions and capital operations between large wind turbine manufacturers are becoming more frequent. Domestic outstanding wind turbine manufacturers are paying more and more attention to the research on the industry market, especially the industrial development environment and product buyers In-depth research. Because of this, a large number of outstanding domestic fan brands have risen rapidly and gradually become the leader in the fan manufacturing industry!
Forecasting from the characteristics of fan demand For small and medium-sized fans with large and widely used products, the product structure and manufacturing process are relatively simple, and the cost is low. The users are mainly pursuing high efficiency, low noise, long life, and cheap prices. The other is capital and technology-intensive, the product structure is complex, the manufacturing cycle is long, the set and system are also strong, and it operates under high pressure, high temperature and high speed conditions, and some even run under harsh conditions. Different types of fans have different requirements. For turbine blowers and compressors and large fans, users are mainly pursuing high quality, high reliability, stable operation and long cycles.
From the demand structure of the main fields, general ventilation fans (generally small and medium-sized centrifugal and axial-flow fans) are most widely used, with the most demand and the most manufacturers. Overall, the supply of such products exceeds demand. Although the demand for special-purpose fans (including anti-corrosion fans, high-temperature fans, wear-resistant fans, fire exhaust fans, etc.) is not large, due to the special operating environment, it needs to be treated differently because the main material requirements are more special. The biggest feature of the 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 relatively large. Through the introduction of technology, joint ventures, and self-development, China has introduced a low-noise three-leaf roots blower, which is quite popular with customers and has a good market prospect. Turbine compressors (including centrifugal compressors, axial compressors, and axial-centrifugal compressors) are important equipment for major engineering complete sets of equipment and play an important role in the national economy. The performance requirements of turbine compressors require both high pressure and large flow. With the large-scale installation, the parameters of turbine compressors are getting higher and higher. Such as blast furnace smelting equipment, large-scale coal chemical equipment, large-scale chemical fertilizer equipment, large-scale ethylene equipment, large-scale air separation equipment, natural gas pipeline transportation equipment, and oil field gas injection equipment. The demand for this type of product accounts for very little of the total amount of fans, but due to its importance, complex structure, long manufacturing cycle, and high technological content, it has relatively good economic and social benefits. The level of turbine compressor manufacturing represents the overall level of the fan industry.
In the wind power industry chain, the long-term development of wind power operators mainly depends on scale advantages and location advantages, that is, resource advantages + scale advantages. The five major power groups as the main force of wind power development not only have a strong installed scale, but also The north area is equipped with a large number of wind farms, and it is expected that after the wind abandonment rate improves in the future, it will contribute to stable profits all year round. The wind turbine manufacturers located in the middle reaches have greater flexibility. Due to the technological and brand advantages of leading wind turbine manufacturers, the concentration of wind turbine manufacturing has been under the major trends of southward development of the project, strengthening of industry rules, and quality ahead of price. Will further enhance, leading manufacturers are expected to gain more market share.
