Automatic feeding mixer is a common vehicle on the construction site. If it goes out suddenly in the process of transportation, it will affect the operation process and the driver's mood. Therefore, the mixer driver must grasp the "first aid" method when the mixer is flameout. What are the common emergency methods?

1、查看油流狀況

1. Check oil flow

小型混凝土攪拌車(chē)熄火后，首要翻開(kāi)油箱開(kāi)關(guān)，拆下輸油泵進(jìn)油管，查看油流的狀況，假如油流斷斷續(xù)續(xù)，闡明油路有問(wèn)題。處理油路今后，運(yùn)用手壓泵排出其間的空氣，擰開(kāi)泵頭的放氣螺釘，氣泡消失后再擰緊。

After the small concrete mixer is flameout, the first thing to do is to turn on the switch of the oil tank, remove the oil inlet pipe of the oil pump, and check the condition of the oil flow. If the oil flow is intermittent, explain that there is a problem in the oil circuit. After handling the oil circuit, use the hand pump to discharge the air between them, and screw on the air release screw of the pump head. After the bubble disappears, tighten it again.

 

2、查看輸油泵活塞和推桿

2. Look at the piston and push rod of the fuel transfer pump

在承認(rèn)油流正常后，拆開(kāi)油泵蓋板，查看推桿是否靈敏，柱塞有無(wú)裂縫。假如一切正常，測(cè)驗(yàn)發(fā)動(dòng)柴油機(jī)中速工作十分鐘，仍呈現(xiàn)熄火狀況時(shí)，敲擊輸油泵大螺帽，留意聽(tīng)柴油機(jī)的聲響，假如聲響反常，闡明輸油泵活塞和推桿卡死，應(yīng)及時(shí)修補(bǔ)替換。

After admitting that the oil flow is normal, remove the cover plate of the oil pump to check whether the push rod is sensitive and whether the plunger has cracks. If everything is normal, when the test engine works at medium speed for 10 minutes and still turns off, tap the big nut of the fuel pump and pay attention to the sound of the diesel engine. If the sound is abnormal, explain that the piston and push rod of the fuel pump are stuck and should be repaired and replaced in time.

3、查看油嘴霧化狀況

3. Check the atomization condition of nozzle

油嘴不霧化也或許導(dǎo)致攪拌車(chē)熄火。能夠拆下油嘴總成查看敞開(kāi)壓力和霧化。假如油嘴總成沒(méi)有問(wèn)題，能夠用油路旁接法進(jìn)行實(shí)驗(yàn)，假如小型混凝土攪拌車(chē)依然熄火，應(yīng)該就是發(fā)動(dòng)機(jī)的問(wèn)題。拆下噴油器總成，滾動(dòng)曲軸，有水噴出，闡明缸蓋、缸體存在裂紋，主張向柴油機(jī)的廠家反映。

If the nozzle does not atomize, it may also cause the mixer to shut down. The nozzle assembly can be removed to check the open pressure and atomization. If there is no problem with the nozzle assembly, it can be tested by using the oil bypass method. If the small concrete mixer is still flameout, it should be the problem of the engine. Remove the fuel injector assembly, roll the crankshaft, there is water spray, clarify the cylinder head, cylinder crack, advocate to the diesel engine manufacturer.

我們?cè)谑褂米詣?dòng)上料攪拌機(jī)在行駛中也有這樣一種常見(jiàn)的問(wèn)題出現(xiàn)，在某些工作環(huán)境中，發(fā)動(dòng)機(jī)水溫必然太高。只要發(fā)生這種情況，就會(huì)對(duì)設(shè)備產(chǎn)生特別的影響。

We are using the automatic feeding mixer, there is also such a common problem in driving, in some working environment, the engine water temperature must be too high. As long as this happens, it will have a special impact on the equipment.
