拖拉机在夏季作业时,没经多长时间,柴油机温度便迅速上升。柴油机温度过高将因热膨胀而使运动的机件卡死;气缸充气量不足,马力下降;机油变薄,润滑性能降低等。因此,在夏季做好冷却系的保养工作显得格外重要。1.检查水箱水位柴油机启动前应检查水箱(散热器)水位。闭式冷却系上水箱的水面应高出散热器芯管子口,不得低于溢水管口8厘米,不足时应及时添加。 When the tractor is working in summer, the temperature of the diesel engine quickly rises without much time. Diesel engine temperature is too high due to thermal expansion and movement of the mechanical stuck; insufficient cylinder inflated, horsepower decline; oil thinning, lower lubrication performance. Therefore, in the summer cooling system maintenance work is particularly important. 1. Check the tank water level Diesel engine should be checked before starting the water tank (radiator) water level. Closed cooling system on the water tank surface should be higher than the radiator core tube mouth, not less than 8 cm overflow pipe mouth, when less than should be added in time.
