Turbine Centrifugal Fan
Features: Turbine centrifugal fan impeller adopts the international standard backward design, the perfect streamline structure, large openings into the center of the impeller inlet wind, the wind through the center port into the wind, resulting in a strong centrifugal force, by the backward tilt fan blades thrown off quickly Turbine structure design makes the wind turbine has a strong wind, wind pressure.
Highlights: Turbine centrifugal fan by the overload thermal motor protection of the outer rotor, high efficiency after the circular arc-shaped centrifugal impeller of two parts. All impeller mold production, high precision dynamic balancing machine calibration, with small size, high efficiency, air volume, small vibration, low noise, superior performance, easy installation and commissioning.
Application: Material: Made of PA6 plastic, plastic one molding process. Diameter size 155mm ~ 250mm.
Applications: Air purification equipment, factory equipment (printing equipment, chemical fiber equipment, etc.), medical equipment, fresh food cabinets, refrigeration cabinets, servo motors, inverters, pipe ventilation, dehumidifiers, etc.
Volute centrifugal fan:
Features: Volute centrifugal fan impeller driven by the motor rotation, the impeller blades forcing gas rotation, the gas to work, to increase its energy, the centrifugal force in the gas around the impeller thrown through the scroll casing will speed Can be converted into pressure energy, when the impeller gas is discharged, the impeller pressure is lower than the pressure inside the inlet, the new gas in the pressure difference under the action of inhalation impeller, the gas is continuously exported from the outlet.
Highlights: The fan is designed with a reasonable impeller angle according to the aerodynamics of air flow. Without any mechanical friction during operation, a reasonable blade shape line minimizes the noise. The optimized impeller minimizes the axial force and has an efficient impeller , And the static and dynamic balance correction, the machine running smoothly, without any damping device, the bearing amplitude is relatively small.
Application: Material: Aluminum die-casting frame, wind wheel made of galvanized sheet, surface black electrophoresis, size Diameter: 120mm ~ 160mm
Applications: Sterilizers, heat exchange systems, clean benches, air shower, laboratory equipment, etc.
choose the suitable fan
1, the first parameter to note are: air volume, total pressure, efficiency, sound pressure level, speed and motor power.
2, Centrifugal fan pressure can be divided into three categories: high pressure centrifugal fan P> 3000Pa, medium pressure centrifugal fan 1000≤P≤3000Pa and low pressure centrifugal fan P <1000Pa. Depending on the stupid physicality and chemical properties of the delivered gas and the use, etc., different types of centrifugal fans are selected.
3, taking into account the loss of air leakage pipeline system, calculation error, as well as the actual fan fan, wind pressure negative deviation, centrifugal fan selection, the general use of air flow rate of 1,05 ~ 1,1, wind pressure of 1,10 ~ 1,15 safety factor. In order to prevent long-term fan in low-efficiency operation, it is not appropriate to use excessive safety factor.
4, in order to make the fan stable operation, should make the fan work in the vicinity of its efficiency, the fan operating point is located in the performance curve of the full pressure peak point on the right (ie, gales side, and is generally located at full pressure peak 80%). Fan design efficiency of the selected conditions, not less than 90% of the fan efficiency.
5, the use of variable frequency fan, the total pressure loss should be calculated as the system rated pressure, but the fan motor power should be calculated on the additional 15% to 20%.

The status of hardware in the home is so important, but the domestic high-end home hardware market and the profitable brand market are mostly occupied by imported hardware companies. According to Luo Baihui, secretary-general of the International Mould and Metals and Plastics Industry Suppliers Association, the total import and export volume of China's hardware industry reached 480 billion yuan in 2012, an increase of 30.1% year-on-year. In the low point of development, the association guided the industry to adjust its strategy and accelerate the transformation. And structural adjustment, from export-oriented to domestic trade and foreign trade at the same time, both domestic and foreign markets, both legs walking, continue to open up the domestic market. This kind of positive and effective action has produced remarkable results, which has triggered a comprehensive rebound, especially the explosive growth in domestic sales, and achieved a high growth rate of 27% in the entire industry.
Luo Baihui said that home life is more and more important to individuals and the requirements for home comfort are getting higher and higher. The lazy style of life that people want nowadays requires hardware to be more humane and intelligent. This is more evident in the cupboard industry where hardware use reaches 35%.
Such as the introduction of electronic smart pumping in the field of foreign high-end cabinets, to achieve a simple design of the cabinet without handles, explosive. The use of new types of damping and slide rails has enabled cabinet drawers to carry heavy load, no rebound, and no leakage, while at the same time prolonging the service life of the damping and slide rails. In the integrated bathroom design, water temperature automatic adjustment of bathroom accessories, card locks, automatic doors, sensor switches, etc. have also begun to enter people's lives, providing the necessary conditions for the home to the direction of intelligent development.
Major brands of furniture and cabinet hardware accessories imported basic hardware companies such as Blum, Hettich and other European companies are taking, the use of German or Italian furniture hardware accessories has become the biggest selling point behind the plate.
With the vigorous development of domestic cabinets, sanitary ware, and other home industries, most companies have begun to pay attention to the vast domestic market. Export to domestic sales has become the focus of corporate strategic development. Home hardware companies are deeply aware of this. In the future, our goal is to deeply intervene in the domestic high-end market. We are already doing research. Luo Baihui believes that due to long-term export abroad or for foreign investment, many domestic companies are very strong in product quality. The key lies in changing the previous practices of heavy production and light brands, and strengthening brand management capabilities and corporate image strategic awareness. This will surely achieve its due market position.
In 2013, China’s hardware industry gradually got rid of the impact of the financial crisis. With the gradual recovery of the domestic and foreign markets, while maintaining the European, American and international markets, China’s hardware companies will also gradually invest their sights in larger markets abroad and add to the domestic market. Big channel and brand building efforts.
In recent years, the hardware industry has developed rapidly, and the scope and number of exports have also been expanding, with broad prospects. With the acceleration of the global economic integration process, China's stainless steel hardware tool processing industry has gradually become the main force of the world's hardware and tools industry. The demand for hardware tools in some developed countries, especially in Africa, the Middle East and other developing countries, is increasing at a rate of more than 10% per year.
At the same time, the requirements of the international market for China's hardware products will gradually evolve and change. There will be higher requirements for the quality, packaging, and delivery deadlines of Chinese products, and even gradually extend to the production process and product development, and the products and the environment , energy resources, and humanities combined. The huge market and central position attraction will further attract the hardware manufacturing center of multinational companies to transfer to China. The integration with foreign companies will continue to enhance the quality and competitiveness of Chinese hardware products. While continuing to expand markets in the United States, Japan, and other traditional countries, Southeast Asia, the Middle East, Russia, Europe, and Africa will also fully blossom.
