炎炎夏日的到来让自动搅拌车司机工作辛苦又沉闷，怎么能少得了空调的陪伴呢？今天和大家分享一下空调系统无风或风力不足时故障排除方法。

The arrival of the hot summer makes the automatic mixer driver work hard and boring. How can he be accompanied by the air conditioner? Today, I would like to share with you the troubleshooting methods for the air conditioning system when there is no wind or the wind is insufficient.

1，鼓风机开关置于任何挡位，出风口均不出风时，应检查熔断器否断路，若熔断器断路，应核对熔断器的容量是否符合要求，检查线路及鼓风机电动机电枢绕组是否搭铁，查明原因并修复或更换。

1. When the blower switch is in any gear and the air outlet is not blowing, first check whether the fuse is open. If the fuse is open, check whether the capacity of the fuse meets the requirements, check whether the circuit and the armature winding of the blower motor are grounded, find out the cause and repair or replace it.

若熔断器良好，则应检查鼓风机开关导线上的电压，电压为零时，应检查空调继电器的线圈是否断路，触点能否闭合，检查线路板及连接线路是否断路，电压正常时，应检查鼓风机开关是否损坏，鼓风机搭铁是否良好，上述检查均正常，则应检修鼓风机电动机。

If the fuse is in good condition, check the voltage on the blower switch wire. If the voltage is zero, check whether the coil of the air conditioner relay is open, whether the contact is closed, whether the central circuit board and the connecting line are open. If the voltage is normal, check whether the blower switch is damaged and whether the blower grounding is good. If the above checks are normal, repair the blower motor.

2，鼓风机电动机仅在某一挡位不能转动时，应检查鼓风机开关该挡位是否导通，该挡分挡电阻间的连接导线及分挡电阻是否断路，并视具体情况给以修复。

2. When the blower motor can not rotate only at a certain gear, check whether the gear of the blower switch is conductive, and whether the connecting wire between the gear and the gear resistance and the gear resistance are open, and repair it according to the specific situation.

3,鼓风机开关置于任何挡位时，鼓风机电运机转动缓慢，各出风口风量均较少，一般是鼓风机电动机损坏或鼓风机开关及连接线接触不良，应检查连接导线各插接件是否松动，鼓风机电动机搭铁是否良好，鼓风机开关各接触点是否良好，后对鼓风机电动机进行检修。

3. When the blower switch is in any gear, the blower motor rotates slowly, and the air volume at each air outlet is small. Generally, the blower motor is damaged or the blower switch and connecting wire are in poor contact. Check whether the connectors of the connecting wire are loose, whether the grounding of the blower motor is good, and whether the contact points of the blower switch are good. Then repair the blower motor.

4，鼓风机电动机运转正常，但个别出风口无风或风量过小，应检查该风口出风罐道中有无异物堵塞，风门能否打开，各边连接管道是否秘封，并视具体情况给以修复。

4. The blower motor operates normally, but there is no air at individual air outlets or the air volume is too small. Check whether there is any foreign matter blocking in the air outlet tank channel of the air outlet, whether the air door can be opened, and whether the connecting pipes at each side are sealed. Repair it according to the specific situation.
