1.离心通风机改用MoS_2锂基脂我厂高炉热风炉助燃采用7-29-11D型离心通风机,风机轴承箱原用80号机械油润滑,轴承箱内设有蛇形冷却水管,轴承箱每次需加油20kg,每8个月更换1次,每台风机年耗油80kg,耗水约8万多吨,设备始终泄漏严重。1984年,我们拆除了轴承箱内蛇形冷却水管,在轴承处安装旋盖式油杯,改用2号二硫化钼锂基脂,结果解决了泄漏问题。经过近3年的使
1. Centrifugal fan switch to lithium-based grease MoS_2 I furnace blast furnace combustion using 7-29-11D Centrifugal fan, fan bearing housing with 80 mechanical oil lubrication, the bearing box is provided with serpentine cooling water pipes, bearings The tank needs refueling 20kg each time, every 8 months to replace 1, each fan annual fuel consumption 80kg, water consumption of about 80,000 tons, the device has always been a serious leak. In 1984, we removed the serpentine cooling pipe in the bearing housing, installed a screw-on oil cup at the bearing and changed to No. 2 molybdenum disulfide grease to solve the leakage problem. After nearly 3 years of use
