攪拌車(chē)熄火自救方法需要注意什么？

來(lái)源：http://pheenet.cn 瀏覽：0發(fā)表時(shí)間：2022-01-13

攪拌車(chē)是建筑工地上的常見(jiàn)車(chē)，如果在運(yùn)輸過(guò)程中突然熄火，會(huì)影響到工作進(jìn)程和司機(jī)情緒。因此攪拌車(chē)司機(jī)一定要掌握攪拌車(chē)熄火時(shí)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(chē)熄火后，打開(kāi)油箱開(kāi)關(guān)，拆下輸油泵進(jìn)油管，檢查油流的情況，如果油流時(shí)斷時(shí)續(xù)，說(shuō)明油路有問(wèn)題。油路以后，使用手壓泵排出其中的空氣，擰開(kāi)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

在確認(rèn)油流正常后，拆開(kāi)油泵蓋板，檢查推桿是否靈活，柱塞有無(wú)裂痕。如果一切正常，嘗試啟動(dòng)柴油機(jī)中速運(yùn)轉(zhuǎn)十分鐘，仍出現(xiàn)熄火情況時(shí)，敲擊輸油泵大螺帽，注意聽(tīng)柴油機(jī)的聲音，如果聲音異常，說(shuō)明輸油泵活塞和推桿卡死，應(yīng)及時(shí)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

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.
