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 running equipment, scientific lubrication management can improve equipment operation, reduce equipment failure and extend equipment operation life. Under normal circumstances, the lubricants are in accordance with the principle of “five fixed, three filter ” equipment shutdown oil change, under the special circumstances also used the same oil online oil change, but almost no choice of different kinds of oil online replacement. Dushanzi Petrochemical ethylene compressor successfully using different types of lubricants online replacement, to solve the bearing high temperature fluctuations, to avoid the unit downtime. Compared with the traditional shutdown oil change method, this method is more economical and can provide reference for similar problems in the same working condition.
