摘要
借鉴石油产品热物理性质的预测模型,利用润滑油的比重和两个温度点的粘度值来计算压缩机润滑油的分子量、不同压力和温度条件下的粘度和密度,有效解决了油气分离器润滑油特性研究中实验数据缺乏的问题。新型自动油平衡油气分离器不仅具有分离压缩机排气中的润滑油的作用,还能自动实现油平衡。在满负荷时抛油管抛油压差为249802 Pa,远远大于抛油管内流动阻力5041 Pa。在低负荷时抛油管抛油压差为5898 Pa,也大于管内流动阻力3936 Pa。
Cited correlations were used to calculate the molecular weight and viscosity and density under different pressure and temperature conditions, it is viable to analyze the characteristics of lubricant in the oil gas separator without enough empirical data. A novel oil gas separator was invented in which the lubricant separated from the exhaust of compressors and the lubricant balance realized automatically. The pressure difference of 249802 Pa is greater than the flow resistance of 5041 Pa in the balance tube under fully loading condition, and the pressure difference of 5898 Pa is also greater than the flow resistance of 3936 Pa in the balance tube under fully loading condition.
