攪拌車熄火自救方法需要注意什么?

來源:http://m.bflrsn.cn 瀏覽:0發表時間:2022-01-13
攪拌車是建筑工地上的常見車,如果在運輸過程中突然熄火,會影響到工作進程和司機情緒。因此攪拌車司機一定要掌握攪拌車熄火時的“急救”方法。
Mixer truck is a common vehicle on construction site. If it suddenly stalls during transportation, it will affect the work process and the driver's mood. Therefore, the mixer driver must master the "first aid" method when the mixer stops.
1檢查油流情況
1 check the oil flow
攪拌車熄火后,首先打開油箱開關,拆下輸油泵進油管,檢查油流的情況,如果油流時斷時續,說明油路有問題。解決油路以后,使用手壓泵排出其中的空氣,擰開泵頭的放氣螺釘,氣泡消失后再擰緊。
After the mixer is turned off, first 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 intermittent, there is a problem in the oil circuit. After solving the oil circuit, use the hand pump to discharge the air, unscrew the vent screw of the pump head, and tighten it after the bubble disappears.
2檢查輸油泵活塞和推桿
2 check the piston and push rod of the fuel transfer pump

在確認油流正常后,拆開油泵蓋板,檢查推桿是否靈活,柱塞有無裂痕。如果一切正常,嘗試啟動柴油機中速運轉十分鐘,仍出現熄火情況時,敲擊輸油泵大螺帽,注意聽柴油機的聲音,如果聲音異常,說明輸油泵活塞和推桿卡死,應及時修理更換。
After confirming that the oil flow is normal, disassemble the oil pump cover plate and check whether the push rod is flexible and whether the plunger is cracked. If everything is normal, try to start the diesel engine and run it at medium speed for ten minutes. If the engine still stalls, knock the large nut of the oil transfer pump and pay attention to the sound of the diesel engine. If the sound is abnormal, it indicates that the piston and push rod of the oil transfer pump are stuck and should be repaired and replaced in time.
3檢查油嘴霧化情況
3 check the atomization of the oil nozzle
油嘴不霧化也可能導致攪拌車熄火。可以拆下油嘴總成檢查開啟壓力和霧化。如果油嘴總成沒有問題,可以用油路旁接法進行試驗,如果攪拌車仍然熄火,應該就是發動機的問題。拆下噴油器總成,轉動曲軸,有水噴出,說明缸蓋、缸體存在裂紋,建議向柴油機的廠家反映。
Failure to atomize the nozzle may also cause the mixer to shut down. The nozzle assembly can be removed to check the opening pressure and atomization. If there is no problem with the nozzle assembly, the test can be carried out by the side connection method. If the mixer still stops, it should be the problem of the engine. Remove the fuel injector assembly, rotate the crankshaft, and water is ejected, indicating cracks in the cylinder head and cylinder block. It is recommended to report to the manufacturer of the diesel engine.
