冷却液应采用清洁干净的软水,采用防冻防锈液更佳。柴油机出水温度控制在
80
℃
~
95
℃
,机油温度控制在
85
℃
~
120
℃
较适宜。(注意正常工作时机油温度是无法控制的,机油温
度一般比出水温度高
15
℃
~
20
℃
)
Clean soft water shall be used as coolant, and it is better to use anti-freeze anti-rust fluid. The
water outlet temperature of the diesel engine shall be controlled at 80
℃~
95
℃
and the oil
temperature shall be controlled at 85
℃~
120
℃
. (it is impossible to control the oil temperature
when normal working, and the oil temperature is 15

higher than water
temperature.)
水泵及风扇是冷却系统的主要部件,其结构如图

小
时应从水泵上的黄油嘴给水泵轴承腔加注一次黄油。
水泵及风扇、充电发电机均通过曲轴皮带轮用同一皮带传动,皮带的松紧度应适宜,不
能过松或过紧,一般在两皮带轮之间向里加
40

型带或多楔带,其规格根据不同的机型有多种,更换时请按旧皮带上
所标规格购买。皮带的松紧度调整可通过调整充电发电机与调节板的相对位置来达到,充电机
往外摆,则皮带张紧,往内摆则皮带放松(图

Water pump and fan are key parts of the cooling system and the structure is as shown in Fig
2-26. Fill grease into water pump bearing tank through the grease nozzle on the water pump
after the diesel engine works for accumulated 50 hours.
The water pump, fan and charging generator are driven by the same belt through crankshaft
belt pulley. The belt shall be of proper tightness. The belt shall be bend 10~15 mm when 40
