① 制冷系统
① Refrigeration system
制冷剂:由管路视液镜观察有无泡沫现象,稍有一点气泡或清澈无气泡则表示冷媒充足,有泡沫表示冷媒不足,需补冷媒。
Refrigerant: whether there is a bubble phenomenon by a pipe optic liquid microscope, and a slight bubble or clear air without bubbles indicates that the refrigerant is abundant, and the foam indicates that the refrigerant is insufficient, and the refrigerant needs to be supplemented.
管路:随时检查各接头处是否渗漏,接头周围无油污为正常,有油污表示有渗漏情况,需检查修复。管路表面有损伤时需增加保护层防护。检修管路时应防潮、防尘。拆卸部件及管路时,应及时将管头或管道封住,以免灰尘和水分进入。
Pipeline: check whether there is leakage at each joint at any time. It is normal if there is no oil pollution around the joint. If there is oil pollution, it means there is leakage, which needs to be checked and repaired. When the pipeline surface is damaged, the protective layer shall be added. The pipeline should be moistureproof and dustproof during maintenance. When removing parts and pipelines, the pipe head or pipe should be sealed in time to avoid dust and moisture entering.
空调制冷效果不佳时,应检查暖风水阀是否关闭。如检查暖风两根黑色软管烫手,则应关闭暖风水阀后再使用空调。
When the cooling effect of air conditioning is poor, check whether the warm air water valve is closed. If you check the two black hot air hoses, you should close the warm air valve before using the air conditioner.

②压缩机
② Compressor
定期检查驱动皮带是否过松及张紧轮内轴承是否运行正常。
Regularly check whether the drive belt is too loose and whether the inner bearing of the tension pulley is running normally.
检查皮带须在发动机停止后方可进行,两轮中间用两指压下7~10MM,稍有弹性者佳。皮带磨损严重时需更换。
Check the belt only after the engine stops. Press down 7-10 mm with two fingers between the two wheels. It is better to have a little elasticity. The belt should be replaced when it is seriously worn.
③ 冷凝器
③ Condenser
冷凝器芯子:表面不要有异物阻碍热交换,表面有异物时要用水轻轻冲掉表面灰尘,注意不得使用高压水或气体进行清理。
Condenser core: there should be no foreign matters on the surface to hinder heat exchange. When there are foreign matters on the surface, the dust on the surface should be gently washed away with water. Attention should be paid not to use high-pressure water or gas for cleaning.
风扇电机:检查是否正常旋转,风量有无变小。
Fan motor: check whether it rotates normally and whether the air volume decreases.
④ 蒸发器
④ Evaporator
蒸发器周围环境:经常保持驾驶室清洁,勿堆积大量杂物,以免妨碍空气循环。
Surrounding environment of evaporator: always keep the cab clean, do not pile up a lot of sundries, so as not to hinder the air circulation.
蒸发器芯子:表面及滤网是否有脏物,有则应立清除表面灰尘或杂物。
Evaporator core: whether there is dirt on the surface and filter screen, if yes, the surface dust or debris should be removed immediately.
风扇电机:检查是否正常旋转。
Fan motor: check for normal rotation.
⑤ 线束
⑤ Wiring harness
检查线夹插头有无松动,检查有无与车体摩擦现象,有此类现象则应固定老靠并加绝缘保护。
Check whether the clamp plug is loose and whether there is friction with the car body. If there is such a phenomenon, it should be fixed and insulated.
