自动搅拌车在使用过一段时间之后，就会有各种各样问题出现，需要及时进行处理，下面来看三个方面的问题吧。

After using the automatic mixer for a period of time, there will be various problems that need to be solved in time. Let's look at three aspects.

一：搅拌车高速行驶时1000搅拌站，时速达到每小时150，但不及时增加档位，速度已超过四千转。这是什么原因

1： When the mixer truck runs at high speed, the speed of 1000 mixing stations reaches 150 kilometers per hour, but the gear is not increased in time, and the speed has exceeded 4000 revolutions. Why

原因：当机油压力电磁阀发生故障时，搅拌车的变速箱将进入倾斜模式，并迫使第三档驱动。此故障是压力调节故障。您需要去商店办理入住手续。尝试更换变速箱油。换油后，将其锁定在第三档，然后需要更换电磁阀。

Cause: When the oil pressure solenoid valve fails, the gearbox of the mixer will enter the tilting mode and force the third gear drive. This fault is a pressure regulation fault. You need to check in at the store. Try changing the transmission oil. After changing the oil, lock it in the third gear, and then replace the solenoid valve.

二：搅拌车打开一段时间后，水温报警灯会自动熄灭，这是什么原因？

2： After the mixer is turned on for a period of time, the water temperature alarm light will go out automatically. What is the reason?

原因：如果发生这种情况，建议检查防冻剂是否已耗尽。如果水箱中缺少防冻剂，应立即将其添加到正常水平。其次，搅拌车会自然损失防冻剂，但不会损失太多。如果发现需要在短时间内频繁添加，则需要检查水箱，水管，加注瓶和小型加热水箱，以检查这些零件是否漏水。

Cause: If this happens, it is recommended to check whether the antifreeze has been used up. If antifreeze is lacking in the water tank, it should be added to the normal level immediately. Secondly, the mixer will naturally lose antifreeze, but not too much. If it is found that it needs to be added frequently in a short time, check the water tank, water pipe, filling bottle and small heating water tank to check whether these parts are leaking.

三：开车时，总是觉得搅拌车制冷不充分。这是要添加的制冷剂吗?

3： When driving, I always feel that the refrigeration of the mixer is insufficient. Is this the refrigerant to be added?

原因：搅拌车中缺少制冷剂的原因主要是由于系统中少量的制冷剂泄漏。如果搅拌车空调系统中的制冷剂不足，从膨胀阀注入蒸发器的制冷剂将不可避免地减少。当搅拌车中的制冷剂在蒸发器中蒸发时，吸收的热量也会减少，冷却能力也会降低减少。建议先去服务站或维修店检查。如果检查结果表明不需要添加，则无需添加，因为混合器中的制冷剂过多是不好的。

Cause: The lack of refrigerant in the mixer truck is mainly due to the leakage of a small amount of refrigerant in the system. If the refrigerant in the air conditioning system of the truck mixer is insufficient, the amount of refrigerant injected into the evaporator from the expansion valve will inevitably decrease. When the refrigerant in the truck mixer evaporates in the evaporator, the heat absorbed will also be reduced, and the cooling capacity will also be reduced. It is recommended to go to the service station or repair shop for inspection first. If the inspection results show that it is not necessary to add, it is unnecessary to add, because it is bad to have too much refrigerant in the mixer.
