High efficiency, low noise is the future development direction of the wind turbine

With the rapid development of science and technology, there are more and more people use fan requirements, according to air conditioning and refrigeration market observation, at present foreign fan technology development trend in terms of, along the fan capacity increasing, the direction of high efficiency, high speed and miniaturization and low noise. < br style='padding: 0px; margin: 0px; color RGB (51, 51, 51); font family: Simsun; font size: 12px; line-height: 30px; '/ > Large fan capacity continues to increase. Increasingly large scale of various industrial devices, the need to objectively require the capacity of various types of fans will continue to increase, the large number of fans in the next few years will be welcomed in the market. < br style='padding: 0px; margin: 0px; color RGB (51, 51, 51); font family: Simsun; font size: 12px; line-height: 30px; '/ > High efficiency. In order to improve the efficiency of the three yuan flow impeller has been more and more widely used in the fan. Other special purposes such as wind turbines and other special purpose of the wind turbine development will be more market. < br style='padding: 0px; margin: 0px; color RGB (51, 51, 51); font family: Simsun; font size: 12px; line-height: 30px; '/ > High speed miniaturization. All kinds of fans with three yuan flow impeller, in improving the efficiency of the same time, the pressure can be improved. Therefore, under the same conditions, the impeller diameter can be reduced by 10% ~ 30%, so that it can achieve the dual effect of reducing the volume and weight. Raising speed is one of the important ways of the air blower. < br style='padding: 0px; margin: 0px; color RGB (51, 51, 51); font family: Simsun; font size: 12px; line-height: 30px; '/ > Low noise. Fan noise is one of the most important sources of noise pollution in industrial production. Large scale and high speed of the wind turbine makes the noise problem is very prominent. To the low frequency noise, the fan is designed by improving the structure of the wind turbine, which can reduce the noise of the main body. If it can not reach the requirement, it can be adopted to install the muffler. < br style='padding: 0px; margin: 0px; color RGB (51, 51, 51); font family: Simsun; font size: 12px; line-height: 30px; '/ > Through the above analysis, it is not difficult to find that the development direction of these technologies is not only the future development trend of the wind turbine, but also the direction of the domestic industry in the technical aspects.
