乙烯压缩机异种润滑油在线置换应用

Heterogeneous Oil Changed on Ethylene Compressor in Non-stop Condition

润滑油是设备运转的血液,科学的润滑管理可以改善设备运行状态、减少设备故障、延长设备运行寿命。一般情况下,润滑油都是按照"五定、三过滤"的原则进行设备停机换油,特殊情况下也采用同种油品在线换油,但几乎不选择异种油品的在线置换。独山子石化乙烯压缩机成功使用异种润滑油在线置换,解决了轴瓦高温波动问题,避免了机组停工。与传统停机换油方法相比较,此方法的经济性较好,可为相同工况的类似问题提供借鉴。

Lubricating oil is the blood of running equipment. Scientific management can improve equipment status, reduce equipment failure and extend the life of the equipment. Generally lubri- cating oil should be changed in stop condition according to the principle of ＂five settings and three-time filtration＂ and same lubricating oil could also be changed in non-stop condition under special circumstances, but heterogeneous oil hardly be changed in non-stop condition. Heterogeneous oil has been changed in non-stop condition on ethylene compressor of Dushanzi Petrochemical Company. Not only the problem of the high temperature and temperature fluctuation of bearing was solved, but also the unit shutdown was avoided. In this method economic benefit is remarkable, compared with the traditional oil changed in stop condition, could provide some advice and reference for this similar question.
