混凝土攪拌車的發動機突然熄火怎么辦
當混凝土攪拌車的發動機突然停止時，不要驚慌。仔細檢查以下5點，攪拌車的困擾:
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.打開油箱開關，從油泵上拆下進油管，觀察油流。如果油流得快，說明它是正常的。
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.當低壓油流暢通后，油路中的空氣可以用手壓泵抽走。打開泵頭放氣螺絲，擰緊放氣螺絲，直到沒有氣泡為止。
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.后確保石油路線暢通和柴油發動機供應系統沒有空氣,油泵的蓋板可以拆卸,鋼板移動控制手柄可以移動,油泵拉桿可以看到移動拉桿是否靈活、柱塞彈簧是否折斷。在拉桿是靈活和柱塞彈簧不壞了,它可以在中速柴油機運行10分鐘,當火壞了,可以使用銅錘輕輕地挖掘燃油泵的大螺母,同時利用一邊聽柴油機聲音,如果聲音不正常,這意味著燃料泵活塞推桿發夾,修理或更換。
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.如果沒有，則應考慮噴油器沒有霧化，油泵柱塞彈簧和彈簧座斷了，卡住不動，或柴油機帶水。拆卸噴嘴總成，檢查開口壓力和霧化情況。如果噴嘴總成正常，請允許用戶將干凈的柴油裝入罐內進行路邊連接試驗。如果仍有斷火現象，應認為是發動機問題。
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.拆下噴油器總成，將曲軸轉動幾次，有水射流、缸蓋、缸體有裂紋或砂眼，在這種情況下，可以向用戶或向柴油機公司說明。引擎的問題將不會被描述。
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.
