一例船舶发电机滑油日耗量增加故障分析

Analysis of a Case of Increased Daily Consumption of Lubricating Oil for Ship's Generators

船舶发电副机系统滑油耗量异常增加时,过多的滑油窜入燃烧室会造成燃烧恶化,严重污染活塞、气缸、气阀、排气道,甚至结焦造成活塞环卡死,影响安全生产。以某型号船舶发电副机滑油日耗不断增加的故障为例,分析滑油油耗增加的常见原因,进行故障排查,得出该型号船舶发电副机滑油油耗的增加并非滑油系统自身的原因,而是由于活塞环制作工艺不完善造成的。因此,在备件的购置和验收时要加强审核,择优选用。日常要对滑油消耗量、吊缸检查、活塞环搭口间隙、磨损测量等进行检查,及时发现故障,排除故障,确保船舶航行安全。

When the oil consumption of a ship’s auxiliary power generator’s system increases abnormally, excessive lubricating oil will enter into the combustion chamber, which will cause combustion deterioration, serious pollution of piston, cylinder, gas valve, exhaust pipe, and even coking, causing the piston ring to become stuck and affecting safe production. Taking a case of failure of increased daily lubricating oil consumption in a ship’s auxiliary power generator, it analyzes the common causes of increased oil consumption and the faults are also checked. It is concluded that the increased fuel consumption of the ship’s auxiliary power generator of this type is not because of the oil system itself, but the imperfect manufacturing process of the piston ring. Therefore, in the process of purchase and acceptance of spare parts, it is necessary to strengthen review and choose premium ones. It needs to carry out routine inspection of oil consumption, lifting cylinder inspection, piston ring clearance, wear measurement, etc., to timely detect faults and solve them to ensure ship’s safe navigation.
