1、打開(kāi)油箱開(kāi)關(guān),拆下輸油泵進(jìn)油管,看油流情況,如果油流很快,說(shuō)明正常,如果油流時(shí)斷時(shí)續查油路。
1. Open the oil tank switch, remove the oil inlet pipe of the oil transfer pump and check the oil flow. If the oil flow is fast, it indicates that it is normal. If the oil flow is intermittent, check the oil circuit.
2、確定油路暢通,柴油機供給系統沒(méi)有空氣后,可拆開(kāi)油泵蓋板,扳動(dòng)操縱手柄,撥動(dòng)油泵拉桿,看拉桿是否靈活和柱塞彈簧是否斷裂。在拉桿靈活和柱塞彈簧沒(méi)斷的情況下,可啟動(dòng)柴油機中速運轉10分鐘,還有斷火現象時(shí),可用一只銅榔頭輕輕敲擊輸油泵大螺帽,一邊敲一邊聽(tīng)柴油機聲音,如果聲音不正常,說(shuō)明輸油泵活塞和推桿發(fā)卡,進(jìn)行修理或更換。低壓油流暢通后,可用手壓泵排除油路中的空氣,打開(kāi)泵頭放氣螺釘,直到?jīng)]有氣泡時(shí),方可上緊放氣螺釘。
2. After confirming that the oil circuit is unblocked and there is no air in the diesel engine supply system, remove the oil pump cover plate, pull the operating handle and pull the oil pump pull rod to see whether the pull rod is flexible and whether the plunger spring is broken. When the pull rod is flexible and the plunger spring is not broken, the diesel engine can be started to run at a medium speed for 10 minutes. In case of fire break, a copper hammer can be used to gently tap the large nut of the oil transfer pump and listen to the sound of the diesel engine while knocking. If the sound is abnormal, it indicates that the piston and push rod of the oil transfer pump are jammed for repair or replacement. After the low-pressure oil flow is unblocked, the air in the oil circuit can be discharged by hand pump, and the bleed screw of the pump head can be opened until there are no bubbles, and then the bleed screw can be tightened.
3、低壓油流暢通后,可用手壓泵排除油路中的空氣,打開(kāi)泵頭放氣螺釘,直到?jīng)]有氣泡時(shí),方可上緊放氣螺釘。

4、如不行則應考慮是油嘴不霧化,油泵柱塞彈簧和彈簧座斷裂,卡死不工作,或是柴油內有水。拆下油嘴總成檢查開(kāi)啟壓力和霧化,如果油嘴總成正常,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。若還有斷火現象應考慮是發(fā)動(dòng)機問(wèn)題。
4. If not, it should be considered that the nozzle is not atomized, the plunger spring and spring seat of the oil pump are broken, stuck and inoperative, or there is water in the diesel oil. Remove the oil nozzle assembly and check the opening pressure and atomization. If the oil nozzle assembly is normal, the user can put clean diesel into the pot and test with the oil circuit side connection method. If there is still a fire break, it should be considered to be an engine problem.
5、拆下噴油器總成,轉動(dòng)曲軸數圈,即有水噴出,說(shuō)明缸蓋,缸體有裂紋或砂眼,遇到這種情況時(shí),可向用戶(hù)解釋或向柴油機公司反映。屬于發(fā)動(dòng)機問(wèn)題就不作敘述。
5. 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 case of this situation, explain to the user or report to the diesel engine company. If it is an engine problem, it will not be described.
