混凝土搅拌车的发动机突然熄火怎么办
当混凝土搅拌车的发动机突然停止时，不要惊慌。仔细检查以下5点，消除搅拌车的困扰:
Don't panic when the engine of the concrete mixer suddenly stops. Carefully check the following 5 points to eliminate the confusion of the mixer:
1.打开油箱开关，从油泵上拆下进油管，观察油流。如果油流得快，说明它是正常的。
1. Open the oil tank switch, remove the oil inlet pipe from the oil pump and observe the oil flow. If the oil flows fast, it is normal.
2.当低压油流畅通后，油路中的空气可以用手压泵抽走。打开泵头放气螺丝，拧紧放气螺丝，直到没有气泡为止。
2. When the low-pressure oil flow is smooth, the air in the oil circuit can be pumped out by hand pressure pump. Open the bleed screw of the pump head and tighten it until there is no bubble.
3.后确保石油路线畅通和柴油发动机供应系统没有空气,油泵的盖板可以拆卸,钢板移动控制手柄可以移动,油泵拉杆可以看到移动拉杆是否灵活、柱塞弹簧是否折断。在拉杆是灵活和柱塞弹簧不坏了,它可以在中速柴油机运行10分钟,当火坏了,可以使用铜锤轻轻地挖掘燃油泵的大螺母,同时利用一边听柴油机声音,如果声音不正常,这意味着燃料泵活塞推杆发夹,修理或更换。
3. After that, make sure that the oil route is unblocked and the diesel engine supply system is free of air, the cover plate of the oil pump can be removed, the steel plate moving control handle can be moved, and the oil pump pull rod can see whether the moving pull rod is flexible and whether the plunger spring is broken. The pull rod is flexible and the plunger spring is not broken. It can run in a medium speed diesel engine for 10 minutes. When the fire is broken, you can use a copper hammer to gently dig the big nut of the fuel pump, and use it to listen to the sound of the diesel engine at the same time. If the sound is abnormal, it means that the piston push rod of the fuel pump is hairpin, repaired or replaced.
4.如果没有，则应考虑喷油器没有雾化，油泵柱塞弹簧和弹簧座断了，卡住不动，或柴油机带水。拆卸喷嘴总成，检查开口压力和雾化情况。如果喷嘴总成正常，请允许用户将干净的柴油装入罐内进行路边连接试验。如果仍有断火现象，应认为是发动机问题。
4. If not, consider that the fuel injector is not atomized, the plunger spring and spring seat of the oil pump are broken, stuck, or the diesel engine has water. Remove the nozzle assembly and check the opening pressure and atomization. If the nozzle assembly is OK, allow the user to load clean diesel into the tank for roadside connection test. If there is still a fire break, it should be considered as an engine problem.
5.拆下喷油器总成，将曲轴转动几次，有水射流、缸盖、缸体有裂纹或砂眼，在这种情况下，可以向用户或向柴油机公司说明。引擎的问题将不会被描述。
5. Remove the fuel injector assembly, turn the crankshaft several times, there is water jet, cylinder head, cylinder block crack or sand hole, in this case, it can be explained to the user or to the diesel engine company. The problem with the engine will not be described.
