滑油分油机作为海上设施大型柴油机组滑油过滤关键设备，其主要功能是对燃油机组使用的滑油进行分离，通过离心分离除去滑油内部的杂质和水分，从而保证滑油质量，避免因滑油变质导致燃油机组运行受损，同时，提升设备使用寿命、降低滑油更换频次，提高经济效益。为降低滑油分油机频繁因排渣转速降低、出口压力低而导致设备故障停机问题，对该故障原因进行分析并提出解决方案，为设备故障处理提供参考依据。

As a key equipment for lube oil filtration in large diesel units of offshore facilities， the main function of the lube oil separator is to separate the lube oil used in the fuel oil unit. Through centrifugal separation， the impurities and moisture inside the lube oil are removed， ensuring the quality of the lube oil and avoiding damage to the operation of the fuel oil unit due to lube oil deterioration. At the same time， the service life of the equipment is improved， the frequency of lube oil replacement is reduced， and the economic benefits are improved. In order to reduce the frequent shutdown of the lube oil separator due to speed reduced during slag discharge and low outlet pressure， the cause of the fault is analyzed and a solution is proposed， providing a reference basis for equipment fault handling.
