  挖掘机的维护、有数的错,标题是倡议机转速失控,俗称“速率”征象因尔后挖掘机维修、越来越多的高速失控,将招致杵柴油倡议机汽缸和分裂轴等庞大变乱,柴油倡议机通常是在启动或变乱负载突然流失或淘汰拦阻发生时车辆,和变乱负载速率下不会发生拦阻,让江苏快三开奖结果对挖掘机维修速率失控的标题举行阐发。
  The maintenance and common faults of excavators are engine speed out of control, commonly known as "speed" phenomenon, which is the current excavator maintenance, more and more high-speed out of control, will lead to major accidents such as diesel engine cylinder and broken shaft. Diesel engine usually fails when starting or working load suddenly disappears or reduces the failure occurs, so that vehicles and working load speed will not fail. The problem of out-of-control maintenance speed of excavator is analyzed.
  1、惯性油浴式气氛滤清器油太多,被吸入气缸内熄灭相称于增长了供油量,也会加快汽车的速率。
  1. Inertial oil-bath air filter has too much oil, which is sucked into the cylinder to burn, which is equivalent to increasing the fuel supply and accelerating the speed of the car.
  2、喷油泵柱塞部件由于陈设倾斜或油封,还可以旋转让调速齿条失失小艇,尤其是多缸油泵会出现负荷淘汰、供油不克不及革新而构成转速下降的环境。
  2. The piston parts of fuel injection pump can also rotate to make the speed control rack lose the boat because of the installation of skew or oil seal. Especially, the multi-cylinder oil pump will reduce the load and the fuel supply can not be changed, which will cause the speed decline.
  3、单缸柴油机燃油泵调速器驱动滑套卡住,招致调速失灵,招致调速失灵。
  3. The sliding sleeve of fuel pump governor of single cylinder diesel engine is stuck, which leads to speed regulation failure and speed regulation failure.
  4,一些放射泵柱塞套筒饲料和回油孔在同一平面位置,要是柱塞套筒定位螺丝太长块回油孔,它将招致前去火油不是免费的,招致火油提供也将激增招致速率。
  4. The feed and oil return holes of some jet pump plunger sleeves are in the same plane position. If the positioning screw of the plunger sleeve is too long, the oil return holes will not be free, and the oil supply will also increase sharply, which will lead to the speed.

  5、燃油放射泵的调油齿在大的供油位置卡住或齿条与调速器拉杆失失控制,会构成调速环境。
  5. The adjusting teeth of fuel injection pump are stuck in the greatest position of fuel supply or the rack and Governor Rod lose control, which will cause speed regulation.
  6日,州长外壳的外部润滑)太多的速率将快甩,影响速率,滑动摩擦聚散器的速率出现,高行长限速螺钉和安全松动,快速崛起或绑定,速率和推力轴承或分裂的弹簧州长轴承粉碎,会招致调速器拦阻。
  On the 6th, the inner lubrication of the governor's housing) too much speed will swing quickly, affecting the speed, the speed of sliding friction clutch, the high-row length speed limit screw and safety loosening, rapid rise or binding, speed and thrust bearings or broken spring governor bearings damage, will lead to governor failure.
  柴油机在高速运转时,如不克不及立刻停车和熄火,将会构成告急结果。因此,当它快速运转时,柴油倡议机必需立刻抑制和失速。告急步伐如下:
  If the diesel engine can not stop and extinguish at high speed, it will cause serious consequences. Therefore, when it runs fast, the diesel engine must stop and stall immediately. Emergency measures are as follows:
  1、窒息进气管,然后柴油机无法吸入气氛就会熄火。
  1. Block the intake pipe, and then the diesel engine will stall if it can't inhale air.
  2、新手驶外形下可采取初等重载,即制动器低出家动机转速后再熄火。
  2. High-grade heavy load can be used in the running state, that is, the brake reduces the engine speed and then extinguishes.
  3.将节流阀手柄置于无供油位置,翻开泄压装置,赌气缸无紧缩力熄灭。
  3. Put the throttle valve handle in the position without oil supply and open the pressure relief device to extinguish the cylinder without compressive force.
  4、用扳手松开高压油管讨论螺母,使柴油机不供油,也可将柴油机放出来。
  4. Use a wrench to loosen the high-pressure tubing joint nut, so that the diesel engine does not supply oil, but also can release the diesel engine.
