摘　　要：针对WK-27大型挖掘机电气室温度过高问题,采用清理或更换滤清器的延时继电器的方法来进行降温。该方法可利用轴流风机先反转然后正转的特点使反转过程中所产生的负压力能有效吸出滤清器中的灰尘杂物等,从而加大电气室的送风量,达到快速降低温度的目的,使故障得到解决。Aim at the problem of excessively high temperature in electric room of WK- 27 large excavator,such solutions as cleaning up or changing time- delay relay of filter are adopted to lower the temperature,which could make the axial flow fan reverses then rotates foreward. In the reverse process,the negative pressure generated could effectively suct the impurities in the filter. As a result,the air output in electric room could be increased so that the temperature could be reduced rapidly and the problem could be solved.
