明確油道通暢，柴油發(fā)動(dòng)機(jī)供給系統(tǒng)軟件沒(méi)有空氣后，可拆卸油泵蓋板，板動(dòng)控制搖桿，撥動(dòng)油泵拉桿，看拉桿是不是靈活和柱塞泵彈簧片是不是決裂。在自上料式混凝土攪拌機(jī)拉桿靈活和柱塞泵彈簧片沒(méi)壞的情況下，可運(yùn)轉(zhuǎn)柴油發(fā)動(dòng)機(jī)中速運(yùn)轉(zhuǎn)十分鐘，再有斷火情況時(shí)，可以用一只銅榔頭輕輕地?fù)舸蜉斢捅么舐菝?，一面敲一面?tīng)柴油發(fā)動(dòng)機(jī)響聲，假設(shè)響聲反常，標(biāo)明輸油泵活塞和推桿發(fā)卡，開展維修或拆換。

When the oil passage is clear and there is no air in the diesel engine supply system software, the cover plate of the oil pump can be removed, the control rocker can be moved, and the pull rod of the oil pump can be moved to see whether the pull rod is flexible and whether the spring plate of the plunger pump is cracked. Under the condition that the pull rod of the self loading concrete mixer is flexible and the spring plate of the plunger pump is not broken, the diesel engine can run at medium speed for 10 minutes. When the fire breaks out again, a copper hammer can be used to gently hit the big nut of the oil pump, and listen to the sound of the diesel engine while knocking. Assuming that the sound is abnormal, it indicates that the piston and push rod of the oil pump are jammed for maintenance or replacement.
              

卸下噴油器總承，旋轉(zhuǎn)曲軸數(shù)圈，即有水噴出來(lái)，標(biāo)明氣缸蓋，缸體有裂縫或沙孔，碰到這類情況時(shí)，可向客戶表述或向自動(dòng)上料攪拌機(jī)公司反應(yīng)。低壓油流通暢后，可以用手壓泵掃除油道中的空氣，翻開泵頭放氣螺釘，直沒(méi)有小氣泡時(shí)，才能扭緊放氣螺釘。

Remove the general bearing of the fuel injector, rotate the crankshaft for several turns, that is, there is water spraying out, indicating that there are cracks or sand holes in the cylinder head and cylinder block. In case of such situation, you can express it to the customer or respond to the automatic feeding mixer company. After the low-pressure oil flow is unobstructed, the air in the oil passage can be swept by the hand pump, and the air release screw of the pump head can be turned over until there are no small bubbles.

油嘴不霧化，油泵柱塞泵彈簧片和彈簧片座決裂，卡死不工作，或者柴油內(nèi)有水。卸下油嘴總承查驗(yàn)翻開壓力和霧化，假設(shè)油嘴總承正常，可讓客戶用潔凈柴油裝入壺中用油路旁接法開展試驗(yàn)。翻開自上料式混凝土攪拌機(jī)油箱開關(guān)，卸下輸油泵進(jìn)油管，看油流情況，假設(shè)油流很快，標(biāo)明正常，假設(shè)油流斷斷續(xù)續(xù)查油道。

The oil nozzle does not atomize, the spring plate and spring plate seat of the oil pump plunger pump are cracked, stuck and does not work, or there is water in the diesel oil. Remove the nozzle general bearing, check the opening pressure and atomization. Assuming that the nozzle general bearing is normal, the customer can load clean diesel into the pot, and carry out the test with the oil bypass method. Turn on the oil tank switch of the self loading concrete mixer, unload the oil inlet pipe of the oil pump, and check the oil flow. Assume that the oil flow is fast and normal. Assume that the oil flow is intermittent and check the oil passage.
