挖掘机配件导致油门异常现象的原因

日期:2018-08-10   来源:/
一、油门不稳:
First, the throttle is unstable.
挖掘机怠速不稳一般是混合气过浓或过稀,点火不完全或挖掘机配件的传感器信号不正确所致。
Unstable idling speed of excavators is usually caused by excessive mixture concentration or thinning, incomplete ignition or incorrect sensor signals of excavator accessories.
1、检查各缸压力,如果汽缸压力不均会导致怠速不稳。
1. Check the pressure of each cylinder. If the cylinder pressure is uneven, idle speed will be unstable.
2、检查燃油压力是否平稳,挖掘机配件喷油器喷油量是否一致,以及喷油器的损坏情况(如有无堵塞或泄漏等)。
2. Check whether the fuel pressure is stable, whether the injection quantity of the injector of the excavator fittings is consistent, and the damage of the injector (such as plugging or leakage).
3、检查挖掘机配件增压压力感器。如果增压压力传感器失效,就不能反馈给发动机ECU正常的信号,起不到修正喷油量的作用,在怠速时供给发动机过浓或过稀的混合气,引起怠速不稳。
3. Check the pressure sense device of the excavator accessories. If the supercharged pressure sensor fails, it can not feed back to the engine ECU normal signal, can not play a role in correcting the fuel injection, in idle speed to supply the engine too thick or too thin mixture, causing idle instability.
二、油门无反应:
Two, throttle no response:
1、首先手动加油门,如手动泵油可加速,即可排除手油泵问题。

2、检查油路有无堵塞、柴滤是否堵塞或脏了,如以上均无异常需考虑高压共轨是否故障。
2. Check whether the oil circuit is blocked, whether the firewood filter is blocked or dirty, if there is no abnormality above, it is necessary to consider whether the high-pressure common rail is faulty.
3、可以检查挖掘机配件油门马达线路是否打铁或马达本身故障。
3, check whether the throttle motor line of excavator is iron or motor itself fault.
三、一直处在大油门状态:
Three, has been in the throttle state:
挖机一启动为大油门,当油门降下来后,发动机转速依然未降,可能原因是某个挖掘机配件低压传感器工作异常,引起程序错误判断机器处于工作状态,所以会出现一启动就是高油门的现象。此外如果油门降下来后,转速无任何变化,则可能是转速传感器出现异常。
As soon as the excavator starts up, the engine speed remains unchanged after the throttle drops down. The reason may be that the low-pressure sensor of some excavator accessory works abnormally, which causes the program to misjudge the machine is in working state, so the phenomenon that a start-up is high throttle appears. In addition, if there is no change in the speed after the throttle down, the speed sensor may be abnormal.
四、发动机油门不正常:
Four. Engine throttle is abnormal.
发动机油门异常对挖机操作很重要,如油门异常不仅会影响工作效率,严重的会导致熄火现象。一般来说江苏挖掘机配件油门异常主要有三种情况,一直高油门、加不上油门、油门忽大忽小。
Abnormal throttle is very important for excavator operation, such as throttle abnormality will not only affect work efficiency, serious will lead to flameout phenomenon. Generally speaking, there are three main kinds of abnormal throttle of Jiangsu excavator accessories. They are always high throttle, can not add throttle, throttle is big or small.
