Blower in the domestic market have no particular advantage to use the blower has been very common in the country, and in our use of the fan will encounter a lot of time in some small and medium sized wind turbines, these fans has been able to occupy the market certain position, mainly because the blower in use some advantages. For some of the advantages as well as some of the problems of the domestic market in the presence of this type of fan blower, we describe in detail for the user. Axial fans and centrifugal fans are used in today's market than the larger of two types of fans, these two types of wind turbines is relatively wide range, including many types of blowers, turbo compressors and blowers two Fan is a typical kind of representative. Represents the level of technological development of the wind turbine industry, such products between the aforementioned technical level there is a certain gap with foreign countries, but the gap is not large, but there are obvious advantages of product price blowers, and high-tech industries and the development of new high-tech products, it is not competitive between the two. In the open market, not the extent of the impact. However, the production of such products business sense of urgency, we must focus on improving the ability to develop innovative, improve product quality and technical content, narrowing the gap with foreign countries. But it is also a development direction of enterprises. Normally, we use the blower is used in some major producers, this fan and turbine compressors and blowers comparison, the price has a very strong advantage, although the price is very low Fuxin lightweight blower, but Blowers also exist some problems, such as the appearance of the quality of the fan susceptible to corrosion, paint often fall off, these are some deficiencies exist fan, these defects are also obstacles to the further development of the fan constraints, therefore, to solve these problems for business is very critical, in which both opportunities and challenges. Centrifugal blower adjustment range to compare different methods of control blower despite a very wide frequency regulation, in the energy has a significant effect, but in the process systems by process conditions, the adjustment range of only 80% to 100%, no change in the relative flow large, the frequency and the guide vane adjustment mode power consumption of the two kinds of difference is not large, so the use of variable frequency adjust blower mode, it does not show up saving specialty Fushun blower function, which lost its significance choice. And the choice of blower vanes adjustment method, while maintaining a constant outlet pressure conditions can adjust the air volume larger range (50% to 100%), in order to ensure stability of the dissolved oxygen content in the water, the relative energy savings. So should choose wicket-speed centrifugal fan adjustment mode, as the selection of equipment for this project. Meanwhile, in order to better reflect the energy-saving effect, centrifugal fan for high-power, attention should also choose matching motor, such as the use of 10kV high-voltage motors, but also help reduce energy consumption efficiency Anshan blowers, blower nagorye (certified), Blowers provided by the Shanxi nagorye blower limited liability company. Shanxi nagorye Blower Co., Ltd. (www.sxgfj.cn) is an industry leader in Shanxi Xinzhou, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In nagorye blower leadership with the staff warmly welcome all inquiries negotiations to create nagorye blower a better future.
