    裝載機突然熄火的原因及解決措施

    內容詳情:
    在駕駛操作井下裝載機時,剎車就是直接控制4個輪的前進或停止,當車輛在有檔位的時候,不踩離合的情況下,發動機和輪子動力上是連為一體的,如果這時候你踩下剎車,輪胎會受到制動力而停下來,這個制動力同樣會連到發動機上阻止發動機的轉動,所以會熄火。當然若是井下裝載機出現以下幾個原因也會導致其突然熄火不動:
    When driving and operating the underground loader, the braking is to directly control the forward or stop of the four wheels. When the vehicle is in a gear position and does not step on the clutch, the engine and the wheels are connected in power. If you step on the brake at this time, the tire will stop under the braking force, which will also be connected to the engine to prevent the engine from rotating, so it will stall. Of course, the following reasons may also lead to the sudden flameout of the underground loader:
    井下裝載機突然熄火的原因及解決措施
    Causes and solutions of sudden flameout of underground loader
    1、發動機出現無怠速故障現象:一般井下裝載機發動機轉速達到1800r/min時才能穩定運轉,而低于1800r/min時會逐漸熄火。在井下裝載機熄火后可以進行以下幾個檢查(1)對CO濃度調整螺釘進行檢查(2)對點火系和供油系進行檢測(3)對怠速穩定閥的控制電流進行了測試。之后在對怠速穩定閥進行更換并重新調速怠速及CO調速螺釘后試車,讓發動機怠速轉速穩定在800r/min,熄火后再次起動,怠速即可正常。怠速穩定閥的作用主要是穩定怠速,而該車怠速穩定閥若是損壞,會直接造成怠速不受控制閥控制而使井下裝載機無法保持正常工作。
    1. There is no idle fault in the engine: generally, the underground loader can run stably only when the engine speed reaches 1800r/min, while it will gradually shut down when it is lower than 1800r/min. The following checks can be carried out after the downhole loader is flamed out: (1) check the CO concentration adjusting screw (2) test the ignition system and oil supply system (3) test the control current of the idle speed stabilization valve. After that, the idle speed stabilizing valve was replaced and the idle speed and co speed regulating screw were adjusted again, the engine idle speed was stabilized at 800r/min, and the engine was started again after flameout, and the idle speed could be normal. The idle speed stabilizing valve is mainly used to stabilize the idle speed. If the idle speed stabilizing valve is damaged, the idle speed will not be controlled by the control valve and the underground loader will not work normally.
    2、井下裝載機在全部檔位的情況下都是熄火,可以嘗試檢查下變速箱,若是其中油里含有大量鋁沫渣子等雜質,則說明該井下裝載機的變矩器壞了。
    2. The downhole loader stalls in all gears, so you can try to check the gearbox. If the oil contains a large amount of aluminum foam residue and other impurities, the torque converter of the downhole loader is broken.
    3、熄火后,直接檢查下高壓泵是否老化需要更換。
    3. After flameout, directly check whether the lower high-pressure pump is aged and needs to be replaced.
    4、重新打火試試能否正常啟動,有時可能是變速箱與發動機的動力輸出軸還處于齒輪嚙合狀態下剎車,導致變速箱傳輸了巨大的反向阻力,而迫使發動機保護性熄火
    4. Spark again to try whether it can be started normally. Sometimes, it may be that the transmission and the power take-off shaft of the engine are still in gear engagement and brake, which causes the transmission to transmit huge reverse resistance and forces the engine to shut down protectively
