摘要 关键词 分油机 故障 维护 保养  Abstract Oil purifier is a important assistant equipment of modern automation ship. Oil purifier is used for refine M D O, L O ,H F O，Oil purifier have a important position of ship motive power device .Oil purifier plays a very important role in the normal working power device。Recent years, with the economic costs of shipping company pursue, shipping companies cut down the economic costs.The technology of marine low-speed diesel engine using heavy oil is mass popular .This inferior heavy oil to M/E 、G/E is a huge wastage .So oil purifier should refine the heavy oil .But when oil purifier deal with poor quality oil ,the oil purifier is very easy to appear some fault 。How to fast judging and solving oil purifier fault ,offering clean oil to ship and gaining safe voyage time is very important . This article according to the working oil purifier principle of the practice and summary by ordinary, oil purifier main will appear run oil phenomenon, appear abnormal vibration or noise, cannot undertake discharging slag, cannot build of hydraulic, gearbox fault water . According to the failure analysis and conduct routine maintenance, ensure oil purifier can stable work.
