摘要
对HG-670/13.7-HM12型锅炉FM340.820型风扇磨煤机轴承箱润滑冷却油系统在运行中存在的问题进行了分析,通过将其外循环强制润滑冷却轴承方式改造为自然对流内循环冷却润滑方式,减少了设备故障率,节省了电能、材料及检修维护费用,提高了设备运行稳定性。
The problems experienced during operation with the bearingbox lubricating oil cooling system for fan/coal grinder FM340.820 of boiler HG-670/113.7-HM12 is awalysed. The forced cooling of bearings through external circulation has been changed to the natural convection cooling through internal circulation.This brings down the failure rate of equipment, saves electric power, material, inspection and maintenance costs, and improves the operational stability of equipment.
