搅拌车行走无力或油温过高怎么办
混凝土自上料搅拌车行走无力或油温过高怎么办？这个问题是使用期间比较常见到的，要想做好预防就要知道原因，下面混凝土自上料搅拌车厂家为您解答。
What should we do if the concrete is unable to walk from the charging mixer or the oil temperature is too high? This problem is common during use. If you want to prevent it, you need to know the reason. The concrete mixer manufacturer will answer it for you.
混凝土自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。
When the concrete 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 problem by conventional testing methods, especially when there is no power, it is more difficult to check the seal rings of the assembled transmission assembly. At this moment, the test can be carried out with a pneumatic valve.
1.将混凝土自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 concrete from the transmission control valve of the charging mixer (the assembled transmission shall be installed before 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. Fill each oil hole of the transmission with 0.6-0.8MPa gas in turn. If a hole is filled with gas, and a "bang" sound is heard, and there is no air leakage or the air leakage sound is very small, the inlet metering pump shall state that the sealing between the corresponding clutch piston and the cylinder barrel is excellent;
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 air leakage is loud, explain the failure of the seal between the clutch piston and the cylinder barrel, and replace the seal.
此外混凝土自上料搅拌车的液压系统如果出现卸荷回路工作不良，当搅拌车系统卸荷回路工作不良或没有卸荷回路，是搅拌车系统不需要压力时，而油液仍在溢流阀所调定的工作压力下溢回油箱，或在卸荷压力较高的情况下流回油路，此时应认真检查系统卸荷回路的工作是否正常，如果卸荷油道被脏物堵塞，或电气系统故障，引起卸荷作用的电磁阀不能工作，应及时采取措施，予以排除。
In addition, if the unloading circuit of the hydraulic system of the concrete self feeding mixer truck does not work well, when the unloading circuit of the mixer truck system does not work well or there is no unloading circuit, the mixer truck system does not need pressure, and the oil still overflows back to the oil tank under the working pressure set by the overflow valve, or flows back to the oil circuit when the unloading pressure is high, then carefully check whether the system unloading circuit works normally, If the unloading oil passage is blocked by dirt or the electrical system fails, and the solenoid valve for unloading cannot work, measures shall be taken in time to eliminate it.
