离心风机发展历史

862年，英国圭贝尔发明离心风机，其叶轮、机壳为同心圆型，机壳用砖制，木制叶轮采用后向直叶片，效率仅为40%左右，主要用于矿山通风。
In 862, guibel invented centrifugal fan in England. Its impeller and shell are concentric and round. The shell is made of brick. The wooden impeller is made of backward straight blades. Its efficiency is only about 40%. It is mainly used for mine ventilation.
1880年，人们设计出用于矿井排送风的蜗形机壳，和后向弯曲叶片的离心风机，结构已比较完善了。
In 1880, people designed the volute shell for mine exhaust and air supply, and the centrifugal fan with backward curved blades. The structure has been relatively perfect.
1892年法国研制成横流风机；1898年，爱尔兰人设计出前向叶片的西罗柯式离心风机，并为各国所广泛采用；19世纪，轴流风机已应用于矿井通风和冶金工业的鼓风，但其压力仅为100～300帕，效率仅为15～25%，直到二十世纪40年代以后才得到较快的发展。
In 1892, France developed the cross flow fan; in 1898, Irish designed the sirocco centrifugal fan with forward blade, which was widely used in many countries; in the 19th century, the axial flow fan had been used in the mine ventilation and the blast of metallurgical industry, but its pressure was only 100-300 PA, and its efficiency was only 15-25%. Until the 1940s, it had a rapid development.

离心风机发展前景

随着我国工业化进程的推进，工业行业正大力开展节能降耗，进行产业升级和整合重组，工业基础设备需要大量更新。离心风机作为工业的重要配套设备，将更多地应用于电力、水泥、石油化工、煤炭、矿山和环保等领域。在新的经济发展形势下，未来离心风机行业将继续保持较快的增长。预计到2022年，离心风机行业市场规模将达到960亿元。
With the development of China's industrialization, the industrial industry is vigorously carrying out energy conservation and consumption reduction, industrial upgrading and integration, and industrial infrastructure needs a lot of updating. As an important supporting equipment in the industry, centrifugal fans will be more used in power, cement, petrochemical, coal, mining and environmental protection fields. In the new economic development situation, the centrifugal fan industry will continue to maintain rapid growth in the future. It is estimated that by 2022, the market scale of centrifugal fan industry will reach 96 billion yuan.

离心风机性能特点

离心风机是依靠输入的机械能,提高气体压力并排送气体的机械,是一种从动的流体机械。具有运行平稳、噪声低、效率高、结构紧、造型美观等特点,离心风机的叶轮和外壳均用铝合金制造,重量轻、防腐性好。离心风机广泛应用于工厂、矿井、隧道、冷却塔、车辆、船舶和建筑物通风、排尘、冷却;锅炉和工业炉窑。

离心风机故障维修

1.离心式通风机转子不平衡引起的振动原因:1、离心式通风机风机叶片被腐蚀或磨损严重;2、风机叶片总装后不运转、由于叶轮和主轴本身重量、使轴弯曲;3、叶轮表面不均匀的附着物,如铁锈、积灰或沥青等;4、运输、安装或...
