If the automatic feeding mixer is not cleaned in time or not cleaned in place, it will lock up if it is not cleaned for a long time. So what problems often occur in automatic loading mixer? How to repair the problem? Let's follow Xiaobian to have a look

一.行走无力或油温过高

1、 Weak walking or high oil temperature

自动上料搅拌车行走无力或油温过高时，就需要判别是离合器活塞密封不严仍是油压缺乏引起的，但惯例检测手段有时很难断定是哪个原因引起毛病，尤其是在无动力的情况下，检查组装

When the automatic feeding mixer truck is unable to walk or the oil temperature is too high, it is necessary to judge whether it is caused by the loose sealing of the clutch piston or the lack of oil pressure, but it is sometimes difficult to determine which cause the problem by conventional detection methods, especially when there is no power, check the assembly

好的变速器总成的各密封环就更困难了。此刻，可采用气压阀进行测试。

Good sealing rings of the transmission assembly are even more difficult. At this point, the pneumatic valve can be used for testing.

1.将自动上料搅拌车变速器控制阀拆掉（对组装好的变速器应在装控制阀之前）；

1. Remove the control valve of the transmission of the automatic feeding mixer (for the assembled transmission, it shall be before installing the control valve);

2.顺次给变速器各油孔通人0.6一0.8MPa的气体，若某一个孔通人气体时，听到"嘭"的一声且无漏气声或漏气声很小进口计量泵，则阐明与之对应的离合器活塞与缸筒间的密封杰出；

2. Successively fill each oil hole of the transmission with 0.6-0.8mpa gas. If a "bang" sound is heard when a hole is filled with gas, and there is no air leakage sound or the air leakage sound is very small, the corresponding sealing between the clutch piston and the cylinder barrel shall be clarified;

3.若听不到活塞压紧摩擦片的动静且漏气声较大，则阐明离合器活塞与缸筒间的密封失效，应替换密封件。

3. If you can't hear the movement of the piston pressing the friction plate and the sound of air leakage is large, it indicates that the seal between the clutch piston and the cylinder barrel is invalid and the seal should be replaced.

二.自动上料拌和机抱轴

2、 Shaft holding of automatic feeding mixer

1.可能是拌和主机进水管与冲水方位原因。冲水点方位和冲刷方向不正确的话，也或者是冲水压力过低，导致水在进入主机内部后，不能将暂时粘结在轴上的混凝土冲刷掉，则时刻久了就简单构成抱轴。

1. It may be caused by the water inlet pipe and flushing direction of the mixing machine. If the flushing point orientation and flushing direction are incorrect, or the flushing pressure is too low, so that the water can not wash off the concrete temporarily bonded to the shaft after entering the main engine, it will simply form the shaft holding after a long time.

2.可能是质料投料方位问题。拌和混凝土所用的物料主要是砂石骨料、水泥、粉煤灰、水和外加剂等。质料水泥若包裹砂石遇水结块，假如拌和不充沛就简单粘在拌和轴上，若水泥进料口方位方向不合理，使拌和轴不能快速充沛拌和，就简单构成抱轴现象。

2. It may be the material feeding direction. The materials used for mixing concrete are mainly sand and gravel aggregate, cement, fly ash, water and admixtures. If the wrapped sand and gravel of the material cement agglomerates with water, if the mixing is not sufficient, it will simply stick to the mixing shaft. If the orientation direction of the cement feed inlet is unreasonable, so that the mixing shaft can not be mixed quickly and sufficiently, it will simply form the phenomenon of shaft holding.

3.在结束作业之后没有及时对拌和机内部进行清洗，或清洗不干净，导致拌和轴外表仍有残留的混凝土，枯燥后凝固在拌和轴上，假如长期如此则十分简单发生抱轴现象。

3. After the operation is completed, the mixer is not cleaned in time, or the cleaning is not clean, resulting in the residual concrete on the surface of the mixing shaft, which is solidified on the mixing shaft after drying. If this is the case for a long time, the shaft holding phenomenon is very simple.

三.自动上料拌和机闷机跳闸原因分析

3、 Cause analysis of stuffy machine trip of automatic feeding mixer

1.投料过多，引起拌和机负荷过大。

1. Excessive feeding causes excessive load of mixer.

2.三角传动皮带太松，使传动体系功率低。

2. The triangular drive belt is too loose, resulting in low power of the transmission system.

3.拌和主机上盖安 全检修开关被振松，引起停机。

3. The safety maintenance switch on the upper cover of the mixing machine was loosened, causing shutdown.

4.拌和体系叶片与衬板之间的空隙过大，拌和过程中，加大了阻力。

4. The gap between the blade and the lining plate of the mixing system is too large, which increases the resistance during the mixing process.
