如何合理地解决长臂挖掘机发动机温度过高的问题!

日期:2019-08-07   来源:上海体彩网http://www.rbaras.com
  由于大部分的挖掘机都是二手的长臂挖掘机,所以在长臂挖掘机超负荷运行时,腰难免断裂。以下是关于长臂挖掘机维修技术是如何消除长臂挖掘机发动机温度过高故障的:
  Because most of the excavators are second-hand long arm excavators, the waist will inevitably break when the long arm excavators are overloaded. The following is about how the maintenance technology of the long arm excavator can eliminate the high temperature fault of the engine of the long arm excavator.
  一、“看”
  I. "Look"
  发现发动机温度过高或温度指示灯不断闪烁,要停止检查,看水箱是否正常,水箱、水管和接头有无漏水现象。如经外部检查未发现异常,可按规定补充冷却水,然后继续工作。如果工作一段时间后温度仍然过高,在停机检查时发现冷却水减少了很多,这主要是由于缸体水套上的砂孔或穿孔损失造成的。当发现这个故障时,应该进行修复,绝不能掉以轻心。

  If it is found that the engine temperature is too high or the temperature indicator flashes continuously, it is necessary to stop checking to see whether the water tank is normal and whether there is water leakage in the water tank, water pipe and joint. If no abnormality is found by external inspection, the cooling water can be supplemented according to the regulations, and then continue to work. If the temperature is still too high after working for a period of time, cooling water is found to be much reduced during shutdown inspection, which is mainly due to the loss of sand holes or perforations on the cylinder block water jacket. When this fault is found, it should be repaired, and must not be taken lightly.
  二、“摸”
  2. "Touch"
  当发动机温度过高时,可以通过触摸水管和水下水管的温度来判断故障。如果两根管子之间的温差很大,可以判断为恒温器不工作。在临时购买配件时,可以紧急拆卸恒温器,等待配件立即更换。
  When the engine temperature is too high, the fault can be judged by touching the temperature of the water pipe and the underwater pipe. If the temperature difference between the two pipes is large, it can be judged that the thermostat does not work. When temporarily purchasing fittings, the thermostat can be disassembled urgently, and the fittings can be replaced immediately.
  三、“放”
  3. Release
  如果冷却系统中有空气,就会形成空气阻力,使冷却水循环不良,导致发动机温度过高。以下方法可以用来释放空气:让发动机在高速运转,轻轻拧开水箱盖,直到一些气体释放,然后一些冷却水将与气体流出,很多次,直到你感觉气(此时,接触上下水管温度将明显不同)。故障排除后,应及时补充冷却水。
  If there is air in the cooling system, it will form air resistance, make the cooling water circulate badly, and cause the engine temperature to be too high. The following methods can be used to release air: let the engine run at high speed, gently unscrew the water tank cover until some gas is released, then some cooling water will flow with the gas, many times, until you feel the gas (at this point, the temperature of contacting the upper and lower pipes will be significantly different). After troubleshooting, the cooling water should be replenished in time.
  四、“冲”
  IV. "Chong"
  长臂挖掘机租赁时如果污物附着在散热器上,久而久之,会影响散热效果,导致水温过高。散热器格栅可先用压缩空气吹制,再用水管冲洗
  If the dirt is attached to the radiator when the long arm excavator is leased, over time, it will affect the heat dissipation effect and cause the water temperature to be too high. The radiator grille can be blown with compressed air before being flushed with water pipes.
  解决长臂挖掘机发动机温度过高问题,一般有“一看、二模、第三方、四冲量”四个步骤。只要掌握了这四个步骤,就可以合理地解决长臂挖掘机发动机温度过高的问题!
  To solve the problem of high temperature of long arm excavator engine, there are generally four steps: "one look, two modes, third sides, four impulse". As long as we master these four steps, we can reasonably solve the problem of high engine temperature of long arm excavator.
