脱硫岛增压风机电机轴承酸腐蚀原因分析及处理

摘 要：本文针对长春二热脱硫岛增压风机电机轴承容易发生酸腐蚀问题进行模拟试验，说明脱硫岛增压风机室内液体，为高温二氧化硫气体形成的亚硫酸，对电机轴承柱有腐蚀作用。通过对5 号炉增压风机电机轴端密封系统密封改造，有效防止了增压风机轴承酸腐蚀现象的发生，保证了其安全稳定运行。

[Abstract] Aiming at Changchun two heat FGD booster fan motor bearing prone toacid corrosion problems of simulation test, the FGD booster fan indoor liquid, sulfurous acid formed as high temperature sulfur dioxide gas, have a corrosive effect on motor bearing column. By sealingthe reconstructionof No. 5 Boiler in booster fan motor shaft end sealing system, effectivelypreventing the bearing booster fan acid corrosion phenomenon, ensure the safe and stableoperation.
