国产装载机工作时,变矩器油温正常范围一般为70～80°C,如果工作中油温超过此范围,甚至达到110～120°C,就属于油温偏高。 1、油温偏高对装载机性能的影响 (1)驱动力不足、离合器摩擦片打滑。变矩器工作油的粘度随温度升高而降低,当温度过高时,工作油会变得很稀,这时,变矩器的内部各密封件的密封性能变差,内漏加重,能量损失加剧,变矩器一级涡轮、二级涡轮的输出扭矩均减小,装载机驱动
Domestic loaders work, the normal torque converter oil temperature range is generally 70 ~ 80 ° C, if the oil temperature exceeds this range of work, or even reach 110 ~ 120 ° C, belong to the high oil temperature. 1, the impact of high oil temperature on the performance of loaders (1) lack of driving force, clutch friction plate slipping. When the temperature is too high, the working oil will become very thin. At this moment, the sealing performance of the internal seals of the torque converter will be worsened, the internal leakage will be aggravated, the energy will increase Loss increased, the torque converter turbine, two turbine output torque decreases, the loader drive
