Wear Resistance TLT Axial Fan Blade 15MnV Steel Industrial Fan Blade Replacement

15MnV Steel blade fan impeller blade

在电力,钢铁,水泥,造纸等行业中大量使用的风机设备,因输送的气体介质中含有大量的硬质粉尘颗粒和酸性气体,这些设备的过流部件,受到强烈的冲刷腐蚀,尤其是其心脏部件叶轮,在其叶片的末端运行线速度达到160米每秒,磨损速度比其它部位更为严重.尤其是风机叶片的磨损最为严重,因而使风机转子的平衡遭到破坏,引起风机振动,缩短风机寿命,严重时可使风机不能正常工作.虽然使用过各种表面防磨措施如堆焊,喷涂,喷焊,涂覆高分子耐磨材料等,使用寿命也难以得到显著提高,比较常用的方法中超音速电弧热喷涂硬质合金耐磨涂层经济实用.

Fan equipment widely used in the electric power, steel, cement, paper and other industries, because the gas medium contains a large number of hard dust particles and acidic gases, the flow parts of these equipment are strongly eroded and corroded, especially the heart part of the impeller, the running line speed at the end of the blade reaches 160 meters per second, and the wear rate is more serious than other parts. In particular, the wear of the fan blade is the most serious, so that the balance of the fan rotor is destroyed, causing fan vibration, shortening the life of the fan, and in serious cases, the fan can not work normally. Although the use of a variety of surface anti-wear measures such as surfacing, spraying, spray welding, coating polymer wear-resistant materials, etc., the service life is difficult to be significantly improved, the more commonly used methods of supersonic arc thermal spraying carbide wear-resistant coating economic and practical.
