摘要
随着矿井生产能力的不断提高,主井提升电机及液压站润滑油等出现温度超过临界值现象,原冷却系统已不能满足要求。根据现场实际情况,对主提升机的冷却系统进行改造,改造后达到了矿井对主井提升机提升能力的要求。
In pace with growth of production capacity, the lubricant temperature of main shaft hoister and hydraulic system rose at same time and went beyond its critical value sometimes. Because the cooling system could not meet the operation requirement, it was transformed according to the actual site situation. The transformation achieves the significant effect and meets the operation requirement fully.
