| 管路清洗 Pipeline cleaning 为确保润滑系统的清净，并供给机械设备轴承以洁净的润滑脂，必须将预安装后的管路拆下清洗。清洗有煤油清洗和酸洗两种。 In order to ensure the cleanliness of the lubrication system and provide clean grease for bearings of mechanical equipment, the pre-installed pipelines must be removed and cleaned. There are kerosene cleaning and acid cleaning. （一）煤油清洗对象及方法 (1) Kerosene cleaning objects and methods 对象。铜管、不锈钢管； Object. Copper pipe and stainless steel pipe; 方法。1、预安装前已经过酸洗处理，且现在内壁无锈蚀、氧化铁皮的钢管； Method. 1. Pipes that have been pickled before Pre-installation and are now free of rust and iron oxide scales on their inner walls; 2、在预装时弄脏的管接头； 2. Pipe fittings dirty at pre-assembly; 3、将需要清洗的管子及接头拆下，管子用布（要不掉毛纱）沾煤油把管内擦净，两端及接头浸泡在煤油中清洗，然后管内涂机油或充填满润滑脂，两端密闭好待装； 3.
