一忌长期不换 拖拉机底壳内的机油,对许多部位进行飞溅润滑,处于雾状,与空气接触面积大大增加,氧化变质较快。同时在工作时,机油经常处于高温环境,废气、金属屑、积炭、尘沙也不断混入,这些都能使机油老化变质,降低润滑性能,加速机件的磨损与腐蚀。在一定期限内,机油消耗 Avoid long-term tractor machine does not change the oil pan bottom, splash lubrication of many parts, in the mist, the contact area with the air greatly increased oxidative deterioration. At the same time at work, the oil is often in high temperature environment, exhaust gas, metal shavings, coke, dust is also constantly mixed, which can make the oil aging deterioration, reduce lubrication, accelerate the wear and corrosion parts. In a certain period of time, oil consumption
