HBZhan Content Introduction:Centrifugal fanIt is a type of fluid machinery with a wide range of applications, including factories, mines, vehicles, computerized car washing machines, and buildings. With the increasing shortage of energy in our country, energy conservation and emission reduction have been widely promoted.
Many industry insiders hold a wait-and-see attitude towards the development of the domestic fan industry. Shanghai Luoze Electromechanical Equipment Co., Ltd. stated that from the perspective of the domestic situation, the development space of domestic fans is still optimistic and will not stagnate as some people think. From the perspective of national development, the usage of fans is constantly increasing, which means that fans are still very popular, especially centrifugal fans. Of course, it is reasonable to say that fans are facing a very severe development situation. However, it depends on how you view the opportunities and challenges in the fan industry.
Most modern fans adopt the ternary flow theory, and the continuous deepening of this theory plays a very important role in the impeller design and overall design of fans. This can not only be applied to impeller design, but also developed into the design of static components for blade diffusers, further improving the efficiency of the unit. Therefore, the use of noise protection technology has also improved the operating environment, and so on.
The development direction of centrifugal fans abroad is large capacity, high pressure, compact structure, low energy consumption, low noise, high efficiency, good plasticity, and strong exhaust purification ability; The commonly used pry without foundation and fully covered low-noise design greatly saves installation, foundation, and commissioning costs; Continuously developing new types of air valves that operate under variable working conditions, greatly improving the service life of the valves; In product design, centrifugal fan thermodynamic and dynamic calculation software, as well as its working process simulation software, are applied to improve calculation accuracy. Through comprehensive simulation models, the performance parameters of the machine under actual working conditions are predicted to improve the success rate of new product development and strengthen mechatronics integration. Our company has formed close cooperative relationships with domestic and foreign suppliers and users, forming a huge network.
Domestic centrifugal fans are relatively backward in terms of design theory and methods. Many product developments use imitation and analogy methods, which seriously lack theoretical basis and experimental research data. The processing equipment and technology level are also relatively backward, with low processing accuracy and production efficiency. The degree of product serialization and generalization is not high, and there are few specifications and varieties. There are still significant gaps in pump efficiency, quality and reliability, sealing performance, corrosion resistance, and other aspects. Although this is our shortcoming, it is also a problem that we can overcome. As long as the problem is solved, domestic centrifugal fans can take another big step towards technology.
With the development of market requirements for wind turbines, our company has further become a regional agent for other companies in China: Kumadaira Co., Ltd. from Japan, the world's largest manufacturer of banking equipment and cultural property protection equipment; CLARK, the world's largest dust collector manufacturer; Swiss Osberg Air Purification System Company, a full range equipment manufacturer of commercial air conditioning end products in Europe.
