  2.在正常范围内,然后继续检查挖掘机主泵的压力值,看主泵是否有问题。
  2. In the normal range, then continue to check the pressure value of the main pump of excavator to see if there is any problem with the main pump.
  3.主泵压力值正常,说明主泵没有问题。
  3. The normal pressure value of the main pump indicates that the main pump has no problem.
  4 .因为挖掘机的工作也是高温锅,所以他们要清洗水箱,检查挖掘机风扇皮带的磨损情况,并且挖掘机的恒温器没有卡住,太原挖掘机的水泵水循环良好。

  6. Because the situation of replacing supercharger of excavator is close, it is suspected that supercharger does not match, so it is checked.
  7.经检查发现增压器是匹配的,因此拆除了重庆挖掘机中冷器,增压器直接与进气口连接,检查是否存在故障。
  7. The supercharger was found to be matched by the inspection, so the intercooler of Chongqing excavator was dismantled. The supercharger was directly connected with the intake port to check whether there was a fault.
  排除故障后,取出中冷器,发现中冷器堵塞。
