摘要:
某公司甲醇制烯烃装置反应气压缩机是日立公司整体供货的离心式压缩机，采用四段两缸布置，透平为杭汽公司供货的背压式汽轮机。该机组于2022-03中上旬检修交出，机组重新开机运行后,高压缸止推轴承温度一直呈上涨趋势，最高达105.9 ℃，影响机组长周期安全稳定运行。对该机组高压缸的止推轴承温度异常升高原因进行了分析排查，制定了多种处理措施，解决了润滑油漆膜问题，轴瓦温度恢复至正常值，保证了机组安全平稳运行，避免了非计划停车，大幅减少了损失。为避免类似问题再次发生，制定了相应的预防措施。
Abstract:
The reaction gas compressor of a methanol to olefin unit in a certain company is a centrifugal compressor supplied by Hitachi as a whole, with a four-stage and two-cylinder arrangement. The turbine is a back pressure steam turbine supplied by Hangzhou Automobile Company. The unit was handed over for maintenance in mid to early March 2022. After the unit was restarted for operation, the temperature of the high-pressure cylinder thrust bearing continued to rise, reaching a maximum of 105.9 ℃, which affected the safe and stable operation of the unit for a long period of time. An analysis and investigation were conducted on the causes of abnormal temperature increase in the thrust bearing of the high-pressure cylinder of the unit, and various treatment measures were formulated to solve the problem of lubricating paint film. The temperature of the bearing shells was restored to normal values, ensuring the safe and stable operation of the unit, avoiding unplanned shutdowns and significantly reducing losses. To avoid similar problems from happening again, corresponding preventive measures have been formulated.
