1、查看油流状况
1. Check oil flow
小型水泥自动搅拌车熄火后,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 small concrete mixer stops, turn on the oil tank switch first, remove the oil inlet pipe of the oil pump, check the oil flow condition, if the oil flow is intermittent, clarify that there is a problem in the oil circuit. In the future, use the hand pump to exhaust the air between them, and screw off the air release screw of the pump head, and then tighten it after the bubble disappears.
2、查看输油泵活塞和推杆
2. Look at the piston and push rod of the fuel transfer pump
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 admitting that the oil flow is normal, remove the cover plate of the oil pump and check whether the push rod is sensitive and whether the plunger has cracks. If everything is normal, test the engine and work at medium speed for 10 minutes. When the engine still shows flameout, knock on the big nut of the fuel pump and listen to the noise of the diesel engine. If the sound is abnormal, it is clarified that the piston and push rod of the oil pump are stuck and should be repaired and replaced in time.

The "first aid" method when the mixing truck stalls introduced by the manufacturer of automatic feeding mixer
3、查看油嘴雾化状况
3. Check the atomization condition of oil nozzle
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,假如小型水泥自动搅拌车依然熄火,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。
If the nozzle does not atomize, it may also cause the mixer to stall. The nozzle assembly can be removed to check the opening pressure and atomization. If there is no problem with the nozzle assembly, the test can be carried out by the oil way side connection method. If the small concrete mixer still stops, it should be the engine problem. Remove the fuel injector assembly, roll the crankshaft, water gushes out, clarify that there are cracks in the cylinder head and cylinder block, and claim to report to the diesel engine manufacturer.
我们在使用自动上料搅拌机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 are using the automatic feeding mixer in the driving also has such a common problem, in some working environment, the engine water temperature must be too high. As long as this happens, it will have a special impact on the equipment.
自动搅拌车在正常道路上会使发动机过热。尽快减速,在树荫下驾驶汽车,或将汽车停在相对凉爽的地方,但不要迅速扑灭大火。
The automatic charging mixer will overheat the engine on normal roads. Slow down as soon as possible, drive the car in the shade of a tree, or park the car in a relatively cool place, but do not put out the fire quickly.
打开引擎盖,以怠速旋转引擎,然后等待直到引擎温度逐渐恢复正常。发动机水温恢复正常后,发动机将停止。请稍等片刻,使发动机水温冷却下来,然后检查发动机冷却水量。
Open the hood, rotate the engine at idle speed and wait until the engine temperature gradually returns to normal. When the engine water temperature returns to normal, the engine will stop. Please wait a moment to cool down the engine water temperature, and then check the engine cooling water quantity.
此时,自动水混合器的冷却水量可能明显不足。补充规定量的冷却水后,检查冷却系统是否有其他异常情况,启动发动机,然后继续运行。另外,检查水箱百叶窗没有被异物堵塞,风扇叶片是否运转,发动机皮带没有打滑以及发动机水泵是否运转。这些都是自动搅拌车行驶中常见的一些故障,简单的应急方案。
At this time, the cooling water of the automatic water mixer may be obviously insufficient. After replenishing the specified amount of cooling water, check whether there are other abnormal conditions in the cooling system, start the engine, and then continue to run. In addition, check that the water tank louver is not blocked by foreign matters, whether the fan blade is running, whether the engine belt is not slipping and whether the engine water pump is running. These are some common faults in the operation of automatic feeding mixer, simple emergency plan.
