First of all, make sure that the oil path of the self feeding flat mouth mixer is smooth. After there is no air in the diesel engine supply system of the self feeding flat mouth mixer, remove the oil pump cover plate, move the control handle, and move the oil pump pull rod to see whether the pull rod is flexible and whether the plunger spring is broken.

在自上料平口攪拌車?yán)瓧U靈活和柱塞彈簧沒斷的情況下，可啟動柴油機中速運轉(zhuǎn)10分鐘，還有斷火現(xiàn)象時，可用一只銅榔頭輕輕敲擊輸油泵大螺帽，一邊敲一邊聽柴油機聲音，如果聲音不正常，說明輸油泵活塞和推桿發(fā)卡，進(jìn)行修理或更換。

The diesel engine can be started to run at medium speed for 10 minutes under the condition that the pull rod of the self feeding mixer is flexible and the plunger spring is not broken. If the fire is still broken, a copper hammer can be used to tap the big nut of the fuel transfer pump gently and listen to the sound of the diesel engine at the same time. If the sound is abnormal, it means that the piston and push rod of the fuel transfer pump are jammed and repaired or replaced.

拆下噴油器總成，轉(zhuǎn)動曲軸數(shù)圈，即有水噴出，說明缸蓋，缸體有裂紋或砂眼，遇到這種情況時，可向用戶解釋或向自上料平口攪拌車公司反映。低壓油流暢通后，可用手壓泵排除油路中的空氣，打開泵頭放氣螺釘，直到?jīng)]有氣泡時，方可上緊放氣螺釘。

Remove the fuel injector assembly and rotate the crankshaft for several turns, that is, 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 self feeding flat mouth mixer company. 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.

油嘴不霧化，油泵柱塞彈簧和彈簧座斷裂，卡死不工作，或是柴油內(nèi)有水。拆下油嘴總成檢查開啟壓力和霧化，如果油嘴總成正常，可讓用戶用干凈柴油裝入壺中用油路旁接法進(jìn)行試驗。打開自上料平口攪拌車油箱開關(guān)，拆下輸油泵進(jìn)油管，看油流情況，如果油流很快，說明正常，如果油流時斷時續(xù)查油路。

The nozzle does not atomize, the plunger spring and spring seat of the oil pump are broken, 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 into the pot and conduct the test by using the oil bypass method. Open the oil tank switch of the self feeding mixer, remove the oil inlet pipe of the oil 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.
