挖掘机的维护,一个非常常见的问题是发动机转速控制故障,通常被称为“飞行汽车”现象,在当前挖掘机维修,越来越多的高速失控,将导致杵柴油机气缸和重大事故,断轴等柴油发动机通常是开始或工作负载突然消失或减少故障发生在车辆、工作负载下不会发生飞车失败。
The maintenance of excavator, a very common problem is the engine speed control failure, which is usually called "flying car" phenomenon. In the current excavator maintenance, more and more high-speed out of control, will lead to pestle diesel engine cylinder and major accidents, broken shaft and other diesel engines usually start or the working load suddenly disappears or reduce the failure, which will not happen under the vehicle and working load Defeat.
1、惯性油浴式空气滤清器油在油中过多，被吸进气缸燃烧相当于增加了供油量，同时也会加速飞车的产生。
1. The inertia oil bath air filter has too much oil in the oil, which is absorbed into the cylinder for combustion, which is equivalent to increasing the oil supply, and at the same time, it will accelerate the generation of the runaway.
2、喷油泵柱塞联轴器由于安装歪斜或油卡死，挖掘机设备还可以旋转使调速齿条失去小艇，特别是多缸油泵会出现负荷下降，供油无法改变，造成飞车。
2. Because the plunger coupling of the fuel injection pump is installed askew or the oil is stuck, the excavator equipment can also rotate to make the speed regulating rack lose the boat, especially the multi cylinder oil pump will have load drop, the oil supply can not be changed, resulting in speeding.
3.摘要单缸柴油机喷油泵调速器驱动滑块卡死，导致调速失灵，导致飞行车辆故障的发生。
3. The slide block of the fuel injection pump governor of single cylinder diesel engine is stuck, which leads to the failure of speed regulation and the failure of flying vehicles.
4、有些注射泵的柱塞套筒在进、回油孔的平面位置相同，如果柱塞套筒的定位螺钉过长堵塞了回油孔，就会造成回油，造成供油激增也会导致飞车飞油。
4. Some injection pump's plunger sleeves are in the same plane position of the oil inlet and return holes. If the locating screw of the plunger sleeve is too long and blocks the oil return hole, it will cause the oil return and the oil supply surge will also cause the oil flying.
5、燃油喷射泵的油量调节齿在供油位置较大时卡住或齿条与调速器杆失去控制，会造成飞车情况。
5. When the fuel regulating teeth of the fuel injection pump are stuck at a large oil supply position or the rack and governor rod are out of control, the runaway situation will be caused.
6,州长外壳的内部润滑)太多的速度将快甩,挖掘机设备影响速度、滑动摩擦离合器的速度出现,高行长限速螺钉和松动,快速崛起或绑定,速度和推力轴承或破碎的弹簧州长轴承损坏,会导致调速器故障。
6. Internal lubrication of governor's shell) too much speed will be thrown away quickly, the speed of excavator equipment affecting speed and sliding friction clutch will appear, high governor's speed limit screw and safety loose, fast rise or binding, speed and thrust bearing or broken spring governor bearing will be damaged, which will lead to governor failure.
