1)为了清除掉在主要润滑系统,存储箱和管道里的杂质
(To remove particles in Main lube oil system, tanks and piping ,etc.)
§喷砂处理(Sand blast)-砂, 鋼片§焊接(Welding)-桿, 棒, 淺
(Spatters)
§其他外来材料-衣料等(Other foreign materials -clothes, etc.)
u 主机启动之前,所有润滑油要流进主机必须要对它进行清洗
(All oil systems flowing into Main Engine must be flushed before Engine start-up)
u 在连接主机管道之前,外部管子应该将汚染物等清洗掉
(External pipes should be free of dirt and particles before connection to engine pipes
2) 为了保持系统清洗油的质量
(To maintain clean oil in the system.)
§清洁NAS 9级(Cleanliness NAS grade 9)or ISO 4406 level 19/15
( Pls contact HHI Supervisor for detail)
3) 防止杂质流进主机
(To prevent Main Engine from particle inflow.)
