Cessna 172型飞机发动机滑油系统的重要任务是把数量足够和黏度适当的滑油循环不断地输送至各摩擦面上。使机件得到良好的润滑,减少摩擦,避免机件的磨损和过热。提高发动机有效功率,增加发动机的使用寿命。1滑油系统的主要功用(1)滑油作用。滑油在运动部件表面保持一层油膜以减小摩擦和磨损,这是润滑的主要作用。润滑油一方面减小由于机件直接接触而造成的磨损,从而延长机件的寿命。另一方面把干面摩擦变成液面摩擦,减小因摩擦而引起的能量损失。因
The important task of the Cessna 172 aircraft engine oil system is to deliver a sufficient quantity and viscosity of the appropriate oil circulation to the friction surfaces. Make the parts get good lubrication, reduce friction and avoid mechanical wear and overheating. Increase the effective power of the engine and increase the service life of the engine. 1 The main function of the oil system (1) the role of oil. Oil keeps a film of oil on the surface of the moving parts to reduce friction and wear, which is the main effect of lubrication. Lubricant on the one hand reduce the wear and tear caused by direct contact with the machine, thereby extending the life of the machine. On the other hand, the dry surface friction becomes liquid surface friction, reducing the energy loss caused by friction. because
