Automatic mixer truck is a common car on construction site. If it suddenly stalls during transportation, it will affect the operation process and the driver's mood. Therefore, the mixer driver must grasp the "first aid" method when the mixer stops. What are the common emergency methods for machinery?

1、查看油流状况

1. Check the oil flow

自动搅拌车熄火后，首要翻开油箱开关，拆下输油泵进油管，查看油流的状况，假如油流断断续续，阐明油路有问题。处理油路今后，运用手压泵排出其间的空气，拧开泵头的放气螺钉，气泡消失后再拧紧。

After the automatic mixer turns off, first turn on the oil tank switch, remove the oil inlet pipe of the oil transfer pump, and check the oil flow. If the oil flow is intermittent, it indicates that there is a problem in the oil circuit. In the future, use the hand pump to discharge the air between them, unscrew the vent screw of the pump head, and tighten it after the bubbles disappear.

2、查看输油泵活塞和推杆

2. Check the fuel transfer pump piston and push rod

在承认油流正常后，拆开油泵盖板，查看推杆是否灵敏，柱塞有无裂缝。假如一切正常，测验发动柴油机中速工作十分钟，仍呈现熄火状况时，敲击输油泵大螺帽，留意听柴油机的声响，假如声响反常，阐明输油泵活塞和推杆卡死，应及时修补替换。

After confirming that the oil flow is normal, disassemble the oil pump cover plate to check whether the push rod is sensitive and whether the plunger has cracks. If everything is normal, test and start the diesel engine to work at a medium speed for 10 minutes. When the engine is still stalled, knock the large nut of the oil transfer pump and pay attention to the sound of the diesel engine. If the sound is abnormal, explain that the piston and push rod of the oil transfer pump are stuck and should be repaired and replaced in time.

3、查看油嘴雾化状况

3. Check nozzle atomization

油嘴不雾化也或许导致搅拌车熄火。能够拆下油嘴总成查看敞开压力和雾化。假如油嘴总成没有问题，能够用油路旁接法进行实验，假如小型混凝土搅拌车依然熄火，应该就是发动机的问题。拆下喷油器总成，滚动曲轴，有水喷出，阐明缸盖、缸体存在裂纹，主张向柴油机的厂家反映。

Non atomization of the nozzle may also lead to flameout of the mixer. The nozzle assembly can be removed to view the open pressure and atomization. If there is no problem with the nozzle assembly, the experiment can be carried out by the oil wayside connection method. If the small concrete mixer still stalls, it should be the problem of the engine. Remove the fuel injector assembly, roll the crankshaft, and water is ejected, indicating that there are cracks in the cylinder head and cylinder block, and it is advocated to report to the manufacturer of the diesel engine.

我们在使用自动搅拌车在行驶中也有这样一种常见的问题出现，在某些工作环境中，发动机水温必然太高。只要发生这种情况，就会对设备产生特别的影响。

We also have such a common problem when using the automatic mixer. In some working environments, the engine water temperature must be too high. As long as this happens, it will have a special impact on the equipment.
