Development of Centrifugal Fans in China
Many professionals in the industry hold a standpoint attitude towards the development of the domestic fan industry. In fact, from the domestic situation, the development space of the domestic fan industry is still very optimistic, and it will not stagnate as some people think. From the perspective of national development, the use of the fan is constantly increasing, which means that Meaning fan is still very popular, especially the use of centrifugal fan is increasing steadily. Of course, there is a basis for saying that fan is facing a very severe development situation. Nevertheless, in the face of the opportunities and challenges of fan industry, it depends on what you think.

Modern fans mostly adopt three-dimensional flow theory, which plays a very important role in the impeller design and overall design of fans. This can not only be applied to the impeller design, but also to the design of static components of vane diffuser. The unit efficiency has been further improved. The noise protection technology has also improved the operating environment and so on.
The development direction of foreign centrifugal fans is large capacity, high pressure, compact structure, low energy consumption, low noise, high efficiency, good plasticity and strong exhaust purification ability; skid mounting without foundation and low noise design with full cover are widely adopted, which greatly saves installation, foundation and commissioning costs; and continuously develop new types of gas operated under variable operating conditions. In product design, centrifugal fan thermodynamics, dynamics calculation software and its working process simulation software are applied to improve the accuracy of calculation, and the performance parameters of the machine under actual working conditions are predicted by comprehensive simulation model, so as to improve the success rate of new product development and make the electromechanical integration. It has been strengthened. Compared with this foreign high-tech fan, we have many shortcomings.
