在两种新型专用磨合油润滑条件下,对某型船用柴油机磨合过程中气缸套、活塞环的磨损失重和表面粗糙度这两个重要参量及摩擦系数随载荷、温度的变化规律进行了模拟试验研究,并与实际使用的普通CD40润滑油的试验结果进行了比较.研究结果表明,磨合过程中使用康胜专用磨合油可使摩擦副表面粗糙度快速下降,可有效地缩短出厂台架磨合试验的进程.而含金属陶瓷添加剂的CD40润滑油,在磨合过程中可显著减小摩擦副的磨损失重和摩擦系数,对避免磨合失效和提高内燃机的使用寿命是有益的.
Under the condition of two new types of special grinding oil lubrication conditions, two important parameters of friction loss and wear loss of cylinder liner and piston ring during the running-in process of a marine diesel engine were simulated by load and temperature And compared with the actual test results of ordinary CD40 lubricating oil.The results show that the use of Kang Sheng special grinding oil in the grinding process can quickly reduce the surface roughness of the friction pair can effectively shorten the factory bench run-in test Of the process.While the CD40 lubricating oil containing cermet additives can significantly reduce the friction loss and friction coefficient of the friction pair during the running-in process, which is beneficial to avoid run-in failure and improve the service life of the internal combustion engine.
