搅拌车发动机突然熄火应该怎么办什么原因?
What should be done when the mixer engine suddenly stops? What's the reason?
在突然熄火时应不要惊慌,仔细检查以下5点以便排除搅拌车故障:
Don't panic in case of sudden flameout. Carefully check the following five points to eliminate the mixer fault:
1、打开油箱开关,拆下输油泵进油管,看油流情况,如果油流很快,说明正常,如果油流时断时续查油路。
1. Open the oil tank switch, remove the oil inlet pipe of the oil transfer pump, and check the oil flow. If the oil flow is fast, it means it is normal. If the oil flow is intermittent, check the oil circuit.
2、低压油流畅通后,可用手压泵排除油路中的空气,打开泵头放气螺钉,直到没有气泡时,方可上紧放气螺钉。
2. After the low-pressure oil flow is smooth, the air in the oil circuit can be removed by hand pressure pump, and the pump head vent screw can be opened until there are no bubbles, then the vent screw can be tightened.
3、确定油路畅通,柴油机供给系统没有空气后,可拆开油泵盖板,板动操纵手柄,拨动油泵拉杆,看拉杆是否灵活和柱塞弹簧是否断裂。在拉杆灵活和柱塞弹簧没断的情况下,可启动柴油机中速运转10分钟,还有断火现象时,可用一只铜榔头轻轻敲击输油泵大螺帽,一边敲一边听柴油机声音,如果声音不正常,说明输油泵活塞和推杆发卡,进行修理或更换。
3. After confirming that the oil circuit is smooth and there is no air in the diesel engine supply system, remove the cover plate of the oil pump, move the control handle and pull the rod of the oil pump to see whether the rod is flexible and whether the plunger spring is broken. When the pull rod is flexible and the plunger spring is not broken, the diesel engine can be started to run at medium speed for 10 minutes. If there is fire break phenomenon, a copper hammer can be used to gently tap the big nut of the fuel transfer pump, and listen to the sound of the diesel engine while knocking. If the sound is abnormal, it means that the piston and push rod of the fuel transfer pump are jammed and repaired or replaced.

4、如不行则应考虑是油嘴不雾化,油泵柱塞弹簧和弹簧座断裂,卡死不工作,或是柴油内有水。拆下油嘴总成检查开启压力和雾化,如果油嘴总成正常,可让用户用干净柴油装入壶中用油路旁接法进行试验。若还有断火现象应考虑是发动机问题。
4. If not, it should be considered that the nozzle is not atomized, the plunger spring and spring seat of the oil pump are broken, stuck, or there is water in the diesel. Remove the nozzle assembly to check the opening pressure and atomization. If the nozzle assembly is normal, the user can load clean diesel into the pot and conduct the test by using the oil bypass method. If there is still fire break phenomenon, it should be considered that the engine problem.
5、拆下喷油器总成,转动曲轴数圈,即有水喷出,说明缸盖,缸体有裂纹或砂眼,遇到这种情况时,可向用户解释或向柴油机公司反映。属于发动机问题就不作叙述。
5. When the fuel injector assembly is removed and the crankshaft is rotated for several turns, water is ejected, which indicates that there are cracks or sand holes in the cylinder head and cylinder block. In this case, you can explain to the user or report to the diesel engine company. If it is an engine problem, it will not be described.
