润滑系统的功用是向发动机各运动摩擦副提供清洁、充足的润滑油。它能否正常工作直接影响发动机的使用性能和寿命,因而做好柴油机润滑系统的预防性维护工作是十分重要的。下面以ZL50型装载机的6135K-9a型柴油机为例,介绍柴油机润滑系统的预防性维护。柴油机主要运动件的摩擦副表面依靠压力和飞溅方式润滑,压力润滑油由齿轮式机油泵提供,经粗滤和冷却后进入各运动件的摩擦副进行润滑,飞溅润滑靠曲轴旋转将连杆轴承中泄漏的润滑油带起而达到润滑的目的。
The function of the lubrication system is to provide a clean, adequate lubricant to the kinematic friction pairs of the engine. It can work directly affect the performance and life of the engine, and diesel engine lubrication system so preventive maintenance work is very important. The following to ZL50 loader 6135K-9a diesel engine, for example, describes the preventive maintenance of diesel engine lubrication system. Diesel main moving parts of the friction surface rely on pressure and splash lubrication, pressure oil provided by the gear pump, after rough filtration and cooling into the friction of the moving parts for lubrication, splash lubrication by crankshaft rotation of the connecting rod bearing Leakage of lubricants brought up to achieve the purpose of lubrication.
