Under the premise of understanding the development space of centrifugal fans , we must first understand some new technical methods of fans on the market, and in combination with the principles of foreign fan use, most modern fans use the ternary flow principle to continuously deepen the The impeller design as well as the overall design play a very important role. This can be applied not only to the design of the impeller, but also to the design of the stationary components of the blade diffuser. The efficiency of the unit has been further improved. The use of noise protection technology has also improved the operating environment and so on. The development space of fans has always been a problem that many companies and manufacturers pay more attention to, especially the centrifugal fans that are widely used in China. The development space of centrifugal fans directly affects the development direction and strategic direction of domestic fan companies. For some types of fan market, it is necessary for us to introduce necessary common sense for enterprises to use for reference. It is undeniable that the use of centrifugal fans in China has been very good, but with the continuous increase of new types of fans In addition, the centrifugal fan is also facing great challenges, but from another direction, it will also provide a good development opportunity for enterprises.
The development direction of foreign centrifugal fans is large-capacity, high-pressure, compact structure, low energy consumption, low noise, high efficiency, good plasticity, strong exhaust purification capacity; generally skid-mounted without foundation, full-cover low-noise design, which greatly saves Installation, foundation, and commissioning costs; continuous development of new types of gas valves that operate under variable operating conditions, greatly improving valve life; in product design, the application of centrifugal fan thermodynamics, dynamics calculation software, and its working process simulation software, etc., to improve Calculate the accuracy, and predict the performance parameters of the machine under actual working conditions through a comprehensive simulation model to improve the success rate of new product development and strengthen mechatronics. Compared with this foreign high-tech fan, it is clear that we have many shortcomings. These technologies are not available in centrifugal fans, and they are also a development direction of centrifugal fans in the future. Before the production of fans, enterprises must go through a rigorous design process so that problems and errors in the design of the fans are as small as possible. It guarantees that the produced fans have the least failures and the lowest losses, which is also the guarantee for the development of centrifugal fans.
Some time ago, the slow growth of the manufacturing industry was an important reason for the weak growth of the centrifugal fan market. In the fourth quarter of the year, the output value of the manufacturing industry of the wind turbine market experienced the highest decline since the first quarter of 2009, and manufacturing industries in Asia and other regions showed a lack of filling. In Mainland China and Hong Kong, growth is slow, while Singapore is in place, but India ’s manufacturing production has indeed expanded substantially, and its related index is still at a relatively low historical level. In comparison, foreign manufacturing production activities have achieved rapid growth, and Turkey's growth rate has reached a new high since the three quarters
China's centrifugal fan machinery industry has many long-term good innate favorable conditions, the market potential is quite large, and the development prospect is extremely broad. From an international perspective, peaceful development cooperation is the mainstream of the times. The overall international environment is conducive to China's peaceful development and construction. The international market has a relatively large demand for Chinese centrifugal fan products. From a domestic perspective, the in-depth development of internationalization such as urbanization, industrialization, marketization, and informatization, and the rapid growth of economic structural transformation, especially China is currently in the process of expanding domestic demand and accelerating infrastructure construction and industrial transformation and upgrading At this stage, there is a very large market demand for advanced fan mechanical equipment.
