自動(dòng)攪拌一體機(jī)是建筑工地上的常見(jiàn)車(chē),假如在運(yùn)送過(guò)程中戛然熄火,會(huì)影響到作業(yè)進(jìn)程和司機(jī)心情。因而攪拌車(chē)司機(jī)一定要把握攪拌車(chē)熄火時(shí)的“急救”辦法。看看機(jī)械常用的應(yīng)急方式有哪些?
Automatic mixer is a common vehicle on the construction site. If it suddenly stalls during 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 stops. What are the common emergency methods for machinery?
1、查看油流狀況
1. Check the oil flow
攪拌一體機(jī)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 all-in-one mixing machine shuts down, first turn on the oil tank switch, remove the oil inlet pipe of the oil transfer pump, and check the oil flow. If the oil flow is intermittent, it indicates that there is a problem in the oil circuit. In the future, use the hand pump to discharge the air between them, unscrew the vent screw of the pump head, and tighten it after the bubbles disappear.
2、查看輸油泵活塞和推桿
2. Check the fuel transfer pump piston and push rod
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 confirming that the oil flow is normal, disassemble the oil pump cover plate to check whether the push rod is sensitive and whether the plunger has cracks. If everything is normal, test and start the diesel engine to work at a medium speed for 10 minutes. When the engine is still stalled, knock the large nut of the oil transfer 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 oil transfer pump are stuck and should be repaired and replaced in time.
3、查看油嘴霧化狀況
3. Check nozzle atomization
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。
Non atomization of the nozzle may also lead to flameout of the mixer. The nozzle assembly can be removed to view the open pressure and atomization. If there is no problem with the nozzle assembly, the experiment can be carried out by the oil wayside connection method. If the small concrete mixer still stalls, it should be the problem of the engine. Remove the fuel injector assembly, roll the crankshaft, and water is ejected, indicating that there are cracks in the cylinder head and cylinder block, and it is advocated to report to the manufacturer of the diesel engine.
我們?cè)谑褂脭嚢枰惑w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 also have such a common problem when using the integrated mixer. In some working environments, the engine water temperature must be too high. As long as this happens, it will have a special impact on the equipment.
