1台使用了1年的原进LJ2000型沥青搅拌站,在北方10月份某气温偏低的早晨生产沥青混凝土时,由于沥青循环泵及喷洒泵不能运转,造成沥青秤中的沥青凝固,最终导致该沥青搅拌站无法正常生产。1.存在问题经检查,导热油炉工作正常。检查沥青循环系统时发现,由于沥青输送管路的温度达不到要求,致使管路中的沥青凝固。分析认为,造成此结果的原因有4点:一是导热油高位油槽过低,导致导热油循环不畅;二是双层管的
One unit used the original LJ2000 asphalt mixing plant which was used for one year. During the production of asphalt concrete in the north with a low temperature in October, the bitumen in the asphalt scale will be solidified due to the inability of the asphalt circulating pump and the spraying pump to run, The asphalt mixing plant can not be normal production. 1. Existing problems After inspection, the conduction oil furnace is working properly. Check the asphalt circulation system found that, due to the asphalt conveying pipe temperature does not meet the requirements, resulting in pipe asphalt solidification. Analysis believes that the reasons for the results of four points: First, HTS high oil tank is too low, resulting in poor circulation of HTF; Second, double-tube
