自上料搅拌车设计合理，结构紧凑，操作灵活，维修方便，可以24小时运转，生产能力高，成本低。下面来讲讲自上料搅拌车离合器活塞密封性的检测。

The self feeding mixer has reasonable design, compact structure, flexible operation, convenient maintenance, can operate 24 hours a day, high production capacity and low cost. Next, we will talk about the sealing test of the clutch piston of the charging mixer.

自上料搅拌车行走无力或油温过高时，就需要判断是离合器活塞密封不严还是油压不足引起的，但常规检测手段有时很难断定是哪个原因引起故障，尤其是在无动力的情况下，检查组装好的变速器总成的各密封环就更困难了，此时，可采用气压阀进行测试。

Since the feeding mixer truck is unable to move or the oil temperature is too high, it is necessary to judge whether the clutch piston seal is not tight or the oil pressure is insufficient. However, it is sometimes difficult to determine the cause of the fault by conventional detection methods. Especially when there is no power, it is more difficult to check the seal rings of the assembled transmission assembly. At this time, the pneumatic valve can be used for testing.

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)，然后依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，则说明与之对应的离合器活塞与缸筒间的密封良好，若听不到活塞压紧摩擦片的声响且漏气声较大，则说明离合器活塞与缸筒间的密封失效，应更换密封件。

Dismantle the control valve of the transmission of the automatic feeding mixer (before installing the control valve for the assembled transmission), and then fill each oil hole of the transmission with 0.6-0.8MPa gas in turn. If one hole is filled with gas, When the sound of "bang" is heard and there is no air leakage or the air leakage is very small, it means that the seal between the corresponding clutch piston and the cylinder barrel is good. If the sound of piston pressing the friction plate is not heard and the air leakage is loud, it means that the seal between the clutch piston and the cylinder barrel is ineffective, and the seals should be replaced.

工作时的注意事项：

Precautions during operation:

1.在冬季施工过程中，应做以下工作：开始前检查是否结冰；关闭工作时，小心地除去搅拌桶和供水系统中的残留水，关闭水泵开关，并将控制手柄置于“停止”位置。

1. During winter construction, the following work shall be done: check whether there is ice before starting; When closing the operation, carefully remove the residual water in the mixing bucket and water supply system, turn off the water pump switch, and place the control handle at the "stop" position.

2.当自上料搅拌车卸货时，如果发现水蒸发了并且坍落度太低而无法满足用户的要求，则可以向桶中适当加水，然后以10-14r/min的速度旋转卸载前先旋转30圈，以使混合充分搅拌。

2. When unloading from the charging mixer truck, if it is found that the water has evaporated and the slump is too low to meet the user's requirements, water can be properly added to the barrel, and then rotate at a speed of 10-14r/min for 30 turns before unloading to fully mix the mixture.

3.在自上料搅拌车的空载运行过程中，不得停止搅拌桶，以免在滚道和支撑辊之间产生局部颠簸，这可能对支撑滚子和滚道造成异常损坏。

3. During the no-load operation of the self loading mixer truck, the mixing drum shall not be stopped to avoid local turbulence between the raceway and the support roller, which may cause abnormal damage to the support roller and raceway.

此外在冬季停放时，水箱和供水系统中应没有剩余水，以防止冻结和破裂。更多相关设备的使用注意事项就来我们网站https://www.zishangliaojiaobanji.cn咨询了解吧！

In addition, when parking in winter, there should be no residual water in the water tank and water supply system to prevent freezing and cracking. More precautions for the use of related equipment can be found on our website https://www.zishangliaojiaobanji.cn Ask and understand!
