理论分析和试验相结合,通过减少风扇叶尖间隙、增大覆盖件开口面积和密封散热器周围间隙等措施降低液压挖掘机热平衡温度,试验证明改进显著。
The combination of theoretical analysis and experiments reduces the heat balance temperature of the hydraulic excavator by reducing the tip clearance of the fan, increasing the opening area of the cover and sealing the clearance around the radiator, and the experiment proves that the improvement is remarkable.
