混凝土全自動攪拌車是建筑工地上的常見車,假如在運送過程中突然熄火,會影響到作業進程和司機心情。因而攪拌車司機一定要把握攪拌車熄火時的“急救”辦法??纯粗锌凭鄯宄S玫膽狈绞接心男??
Automatic concrete mixer is a common vehicle on construction site. If it suddenly goes out 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 flameout. What are the common emergency methods of China Science and technology summit?
1、查看油流狀況
1. Check oil flow
混凝土全自動攪拌車熄火后,首要翻開油箱開關,拆下輸油泵進油管,查看油流的狀況,假如油流斷斷續續,闡明油路有問題。處理油路今后,運用手壓泵排出其間的空氣,擰開泵頭的放氣螺釘,氣泡消失后再擰緊。
After the full-automatic 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 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
在承認油流正常后,拆開油泵蓋板,查看推桿是否靈敏,柱塞有無裂縫。假如一切正常,測驗發動柴油機中速工作十分鐘,仍呈現熄火狀況時,敲擊輸油泵大螺帽,留意聽柴油機的聲響,假如聲響反常,闡明輸油泵活塞和推桿卡死,應及時修補替換。
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致攪拌車熄火。能夠拆下油嘴總成查看敞開壓力和霧化。假如油嘴總成沒有問題,能夠用油路旁接法進行實驗,假如小型混凝土攪拌車依然熄火,應該就是發動機的問題。拆下噴油器總成,滾動曲軸,有水噴出,闡明缸蓋、缸體存在裂紋,主張向柴油機的廠家反映。
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.
我們在使用混凝土全自動攪拌車在行駛中也有這樣一種常見的問題出現,在某些工作環境中,發動機水溫必然太高。只要發生這種情況,就會對設備產生特別的影響。
We are using the automatic concrete 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.
