Automatic concrete mixer in use will encounter this situation: automatic concrete mixer mixing tank idle speed does not rotate, so what is the cause? Let's take a look.

自动混凝土搅拌车搅拌罐的工作转速是不能低于650转/分，按照重型底盘发动机的设计参数可知它的正常工作转速为950转/分，在工作过程中，如果出现自动混凝土搅拌车罐怠速不转，我们可以从以下三个方面着手，我们一起来看看可能会导致自动混凝土搅拌车罐怠速不转的三个原因：

The working speed of the mixing tank of the automatic concrete mixer truck should not be lower than 650 rpm. According to the design parameters of the heavy chassis engine, it can be known that its normal working speed is 950 rpm. In the working process, if the automatic concrete mixer tank does not rotate at idle speed, we can start from the following three aspects. Let's take a look at the possible causes of the tank idling of the automatic concrete mixer truck There are three reasons for not turning fast
              

一、看一下液压油是否干净，在散热器上有一个负压表，如果表针指到红色区域表示该换油换滤芯了；

1、 Check whether the hydraulic oil is clean. There is a negative pressure gauge on the radiator. If the indicator needle points to the red area, it means that the oil should be changed and the filter element should be changed;

二、也有可能表头出现故障，可直接查看一下，液压是否发黑，或者乳化；

2、 It is also possible that the meter head fails, and you can directly check whether the hydraulic pressure is blackened or emulsified;

三、测试压力，看有无液压梭阀堵塞现象，有专人现场确认。

3、 Test the pressure to see if there is blockage of the hydraulic shuttle valve, and special personnel shall confirm it on site.

以上三个原因会导致自动混凝土搅拌车罐怠速不转，车主朋友们可根据情况逐一排查及问题。

The above three reasons will lead to the automatic concrete mixer tank idling, car owners can check and solve the problem one by one according to the situation.
