柴油机活塞环断环原因分析及管理
[摘要]在大型船舶柴油机燃烧室诸多构件中,活塞环是主要的组成零件之一。由于其复杂的运动状态和恶劣的工作环境，活塞环又是柴油机的易损件之一。活塞环的工况直接影响主机工作过程的好坏，同时也影响主机的安全运行和使用寿命。活塞环作为柴油机的主要受热零件之一，长期工作在恶劣的环境下，承受很高的热负荷，活塞环恶劣的工作环境导致活塞环容易发生故障极大地危害柴油机整机的可靠性和耐久性。因此，活塞环在运行中的管理和维护对保证柴油机安全,可靠和经济运行显得非常重要。针对船用柴油机常见的活塞环折断故障，本文以“南海502”轮上LB6250ZLC-6型主机为例，分析出造成该故障出现的主要原因——环槽积碳、气缸套磨台、环槽过度磨损、活塞环挂住气口和活塞环径向胀缩疲劳，并在此基础上提出相应的预防措施和对策，并对活塞环的日常管理和维护提出了切实可行的管理建议。

The Reason Analysis and Countermeasure of Piston Ring Breaking of Diesel Engine
[Abstract]Pistonrings are the maincompositespartsin the combustionchamber of the Marine Diesel Engine. For its badly working condition and the piston rings can be easily damaged.The working condition of pistonring has much influence on the working quality of diesel engine such as efficiency, mobility and reality. And so how to keep the pistonringworking in good condition is becoming one of main tasks for the engineers.Harsh environment can cause the piston ring fault.So, Good management and maintenance for piston rings are very important for safety running of the Diesel Engine .Aimat usual fault of piston ring breaking of marine diesel engine,As an example inLB6250ZLC-6M.E. on board of “South China Sea502”,this paper analyzes the fault of broken piston ring and givesthe causes including cumulated carbon in the ring-slot, abrasion of cylinder jacket over-abrasion of slot, air-vent of piston ring and expanding-shrinking fatigue at radial direction.And onthis basis,present correspondingprecautionary measures and countermeasure and give practical management advice to daily managementand maintenance for piston ring.
