Why does the automatic mixer stop suddenly?

確認(rèn)油路暢通，柴油機(jī)供應(yīng)系統(tǒng)沒(méi)有空氣后，可拆開(kāi)油泵蓋板，板動(dòng)操作手柄，撥動(dòng)油泵拉桿，看拉桿是否靈敏和柱塞繃簧是否開(kāi)裂。在自動(dòng)上料混凝土攪拌車(chē)?yán)瓧U靈敏和柱塞繃簧沒(méi)斷的情況下，可發(fā)動(dòng)柴油機(jī)中速運(yùn)轉(zhuǎn)10分鐘，還有斷火現(xiàn)象時(shí)，可用一只銅榔頭悄悄敲擊輸油泵大螺帽，一邊敲一邊聽(tīng)柴油機(jī)聲響，假如聲響不正常，闡明輸油泵活塞和推桿發(fā)卡，進(jìn)行修補(bǔ)或替換。

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 operating handle and pull the rod of the oil pump to see whether the rod is sensitive and whether the plunger spring is cracked. Under the condition that the pull rod of the automatic feeding concrete mixer is sensitive and the tension spring of the plunger is not broken, the diesel engine can be started to run at medium speed for 10 minutes. In case of fire break, a copper hammer can be used to tap the big nut of the oil pump quietly, and listen to the sound of the diesel engine at the same time. If the sound is abnormal, it is clarified that the piston and push rod of the oil pump are jammed and repaired or replaced.
                 

拆下噴油器總成，滾動(dòng)曲軸數(shù)圈，即有水噴出，闡明缸蓋，缸體有裂紋或砂眼，遇到這種情況時(shí)，可向用戶(hù)解說(shuō)或向自動(dòng)攪拌車(chē)公司反映。低壓油流暢通后，可用手壓泵掃除油路中的空氣，翻開(kāi)泵頭放氣螺釘，直到?jīng)]有氣泡時(shí)，方可上緊放氣螺釘。

Remove the fuel injector assembly and roll the crankshaft for several turns, that is, there is water gushing out, indicating 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 automatic mixer company. After the low-pressure oil flow is smooth, the air in the oil circuit can be swept by the hand pump, and the air release screw of the pump head can be turned over until there are no bubbles, then the air release screw can be tightened.

油嘴不霧化，油泵柱塞繃簧和繃簧座開(kāi)裂，卡死不工作，或是柴油內(nèi)有水。拆下油嘴總成查看開(kāi)啟壓力和霧化，假如油嘴總成正常，可讓用戶(hù)用干凈柴油裝入壺中用油路旁接法進(jìn)行試驗(yàn)。翻開(kāi)自動(dòng)攪拌車(chē)油箱開(kāi)關(guān)，拆下輸油泵進(jìn)油管，看油流情況，假如油流很快，闡明正常，假如油流時(shí)斷時(shí)續(xù)查油路。

The nozzle does not atomize, the tension spring of the pump plunger and the tension spring seat are cracked, stuck and does not work, or there is water in the diesel oil. Remove the nozzle assembly to check the opening pressure and atomization. If the nozzle assembly is normal, the user can load clean diesel oil into the pot and carry out the test with the oil bypass method. Turn on the oil tank switch of the automatic mixer, remove the oil inlet pipe of the oil pump, and check the oil flow. If the oil flow is fast, it is normal. If the oil flow is intermittent, check the oil circuit.
