我厂引进捷克φ250半连续轧钢车间,有4个同步发电机组和13架轧机,分别由3个稀油站和6个干油站集中供油。其中电机轴瓦和轧机主传动轴轴承由稀油站统一供22号透平油。由于22号透平油粘度低,以及润滑方式不合理等原因,造成主传动轴轴承座长期严重漏油,以致车间和主电室污油满地,影响车间正常安全生产,严重污染环境,而且油料浪费严重。因此,我厂于1989年3月设备大修改造时,对主传动轴轴承润滑进行了彻底改造。 1.稀油润滑改为油脂润滑 在轧钢生产中,主传动轴轴承因受载而
I plant the introduction of Czechoslovakia φ250 semi-continuous rolling plant, there are four synchronous generating units and 13 rolling mills, respectively, by the three thin oil stations and six dry gas stations focus on oil supply. Among them, the motor bearing pad and the main drive shaft bearing of the rolling mill are provided with No. 22 turbine oil uniformly by the thin oil station. Due to the low viscosity of 22 # turbine oil, and the lubrication method is not reasonable and other reasons, resulting in long-term main bearing housing leaks, resulting in workshop and main electrical room full of oil, affecting the workshop normal safe production, serious environmental pollution, and Heavy oil waste. Therefore, I plant in March 1989 equipment overhaul, the main shaft bearing lubrication has been completely transformed. 1. Thin oil lubrication to grease lubrication In the rolling production, the main drive shaft bearing due to load
