滑油压力是活塞发动机台架试车时最重要的监控参数之一,低滑油压力会导致发动机各摩擦副表面润滑不良,从而使发动机的各部件过早磨损,严重时会使发动机彻底失效。文中以莱康明IO-360-L2A航空活塞发动机为例,分析了导致滑油压力低的原因。
Lubricating oil pressure is one of the most important monitoring parameters when testing the piston engine bench. Low oil pressure can cause poor lubrication on the surface of each friction pair, leading to premature wear of engine parts and serious failure of the engine. Taking the Lycoming IO-360-L2A aviation piston engine as an example, the reason of low oil pressure is analyzed.
