装载机突然熄火的原因及解决措施

来源:http://www.kuangjingjixie.com/ 发布时间:2022-05-27 浏览次数:200

内容详情:
在驾驶操作井下装载机时,刹车就是直接控制4个轮的前进或停止,当车辆在有档位的时候,不踩离合的情况下,发动机和轮子动力上是连为一体的,如果这时候你踩下刹车,轮胎会受到制动力而停下来,这个制动力同样会连到发动机上阻止发动机的转动,所以会熄火。当然若是井下装载机出现以下几个原因也会导致其突然熄火不动:
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:
井下装载机突然熄火的原因及解决措施
Causes and solutions of sudden flameout of underground loader
1、发动机出现无怠速故障现象:一般井下装载机发动机转速达到1800r/min时才能稳定运转,而低于1800r/min时会逐渐熄火。在井下装载机熄火后可以进行以下几个检查(1)对CO浓度调整螺钉进行检查(2)对点火系和供油系进行检测(3)对怠速稳定阀的控制电流进行了测试。之后在对怠速稳定阀进行更换并重新调速怠速及CO调速螺钉后试车,让发动机怠速转速稳定在800r/min,熄火后再次起动,怠速即可正常。怠速稳定阀的作用主要是稳定怠速,而该车怠速稳定阀若是损坏,会直接造成怠速不受控制阀控制而使井下装载机无法保持正常工作。
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、井下装载机在全部档位的情况下都是熄火,可以尝试检查下变速箱,若是其中油里含有大量铝沫渣子等杂质,则说明该井下装载机的变矩器坏了。
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,直接检查下高压泵是否老化需要更换。
3. After flameout, directly check whether the lower high-pressure pump is aged and needs to be replaced.
4、重新打火试试能否正常启动,有时可能是变速箱与发动机的动力输出轴还处于齿轮啮合状态下刹车,导致变速箱传输了巨大的反向阻力,而迫使发动机保护性熄火
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
