【摘要】:通过对K-5001低压溶剂回收压缩机轴瓦磨损原因进行分析,发现润滑油中有烃类气体溶解,导致润滑油运动黏度下降严重。为减少烃类气体在润滑油的溶解,选择合成基础油,根据压缩机工况以及轴瓦处最小许用黏度,确定润滑油黏度范围,最后选择一种适合烃类压缩机的合成机油。实际运行结果表明,烃类气体对该润滑油的黏度影响较小,润滑油能够满足设备工况要求。
[Abstract]:By analyzing the wear causes of bearing bush of K-5001 low pressure solvent recovery compressor, it is found that hydrocarbon gas dissolves in lubricating oil, which results in the decrease of lubricating oil viscosity. In order to reduce the dissolution of hydrocarbon gas in lubricating oil, the synthetic base oil is selected. According to the minimum allowable viscosity of compressor and bearing bush, the range of viscosity of lubricating oil is determined. Finally, a synthetic oil suitable for hydrocarbon compressor is selected. The actual operation results show that hydrocarbon gases have little effect on the viscosity of the lubricating oil and the lubricating oil can meet the requirements of the equipment working conditions.
