众所周知，在自动上料搅拌车固定时间一段时间后就要对其进行保养或者维修，一是及时发现问题及时，二是相应延长设备的使用寿命，但是有一些常识性错误会出现，下面来讲讲。

As we all know, the automatic feeding mixer needs to be maintained or repaired after a fixed period of time. First, problems should be found and solved in a timely manner. Second, the service life of the equipment should be extended accordingly. However, some common sense errors may occur. Let's talk about them below.

螺栓螺母都涂上润滑油？

The bolts and nuts are coated with lubricating oil?

在自动搅拌车的车轮维修中，少数搅拌车司机为了防止车轮上螺栓螺母生锈，安装时别出心裁地将螺栓螺母都涂上润滑油，殊不知这种做法不仅错误，而且给自动搅拌车行车带来一定的隐患。

During the maintenance of the wheels of the automatic mixer, a few mixer drivers applied lubricating oil to the bolts and nuts of the wheels to prevent them from rusting. However, this practice was not only wrong, but also brought some hidden dangers to the driving safety of the automatic mixer.

螺栓和螺母拧紧后，相互间具有自锁的特性。而涂上润滑油后，二者之间的自锁系数变小、自锁性能下降。在自动搅拌车高速行驶时，螺栓螺母很容易松动乃脱落，从而引发自动搅拌车行车事故。

After the bolts and nuts are tightened, they are self-locking with each other. However, the self-locking coefficient between the two becomes smaller and the self-locking performance decreases after being coated with lubricating oil. When the automatic mixer truck is running at high speed, the bolts and nuts are easy to loosen and even fall off, thus causing driving accidents of the automatic mixer truck.

用水冲洗车身?

Rinse the body with water?

车身内部好不要用水直接冲洗。因为驾驶室内地板胶垫的下面可不是“一马平川”，结构上的需要使驾驶室地板胶垫下面的凹槽、通孔非常多。

The interior of the car body should not be washed directly with water. Because the underside of the cab floor rubber pad is not "flat", the structural needs make there are many grooves and through holes under the cab floor rubber pad.

用水冲洗后，要么沉积在凹槽内不易干燥，要么从通孔处流到自动上料搅拌车变速箱等部件上产生锈蚀。尤其是密封性能较好的自动上料搅拌车更不能用水直接冲洗车身内部。正确的方法是用湿抹布擦拭，但要避免积水。

After washing with water, it is either deposited in the groove and not easy to dry, or it flows from the through-hole to the gearbox of the automatic feeding mixer truck and other parts to cause corrosion. In particular, the automatic feeding mixer with good sealing performance cannot directly flush the interior of the vehicle body with water. The correct method is to use a wet rag to wipe, but to avoid water accumulation.

冷却液的混合使用？

Mixed use of coolant?

谁都知道自动上料搅拌车发动机冷却液不足时应及时添加，但司机是否把不同企业的冷却液温在一起使用了呢?如果是，劝司机还是趁早把冷却液放掉，重新添加同一企业的冷却液。

Everyone knows that when the engine coolant of the automatic feeding mixer is insufficient, it should be added in time, but has the driver warmed the coolant of different brands together? If yes, the driver is advised to drain the coolant as early as possible and add the same brand of coolant again.

因为不同企业的冷却液其化学性能可能相差悬殊，比如对黑色金属有效的防腐剂，却常常对自动上料搅拌车铝制品有腐蚀作用;而适用于铝台金的防腐剂则对铁合金有害。由于不同企业的冷却液所用的防腐剂不同，所以不能混合使用。

Because the chemical properties of different brands of coolants may vary greatly, for example, the effective preservatives for ferrous metals often corrode the aluminum products of the automatic feeding mixer; The preservative suitable for aluminum alloy is harmful to ferroalloy. As different brands of coolant use different preservatives, they cannot be mixed.

此外要明白，自动上料搅拌车发动机启动时，没有必要踩油门，更不要在启动前连续急踩，否则反而使自动上料搅拌车发动机启动不良。关注我们http://www.sdzkjf.cn，了解更多使用事项！

In addition, it should be understood that it is not necessary to step on the accelerator when the engine of the automatic feeding mixer is started, let alone continuously step on the accelerator before starting, otherwise the engine of the automatic feeding mixer will not start well.
