一台装载机(属ZL系列)在作业过程中,液力变矩器的油温持续超过120℃并出现如下现象,如加油口冒油烟、驱动无力、速度降低、变速泵异响、变速压力过低。油温过高易使油液氧化变质、黏度降低、传动和润滑功能下降,加速内漏和零件磨损、橡胶密封失效,甚至造成机械事
A loader (ZL series) in the course of the operation, the torque converter oil temperature continued to exceed 120 ℃ and the following phenomena, such as the fume hood fumes, drive weakness, speed reduction, variable speed pump noise, variable speed pressure Too low. Oil temperature is too high easy to oxidative deterioration of oil, viscosity decreased, transmission and lubrication functions to speed up the internal leakage and parts wear and tear, rubber seal failure, and even cause mechanical things
