【摘要】 针对生产的实际需要,为保证用于沥青罐加热的导热油能顺利返回到导热油锅炉,一般采用适当提升导热油压力的方法。对整个管路的压降进行了计算,并对管道的沿程摩阻和局部摩阻进行了详细讨论和计算,得出了管线沿程的总压降。通过相关数据计算了导热油的流量,提出了用于压力提升的离心泵的选择方案。更多还原

【Abstract】 According to the actual production,in order to guarantee asphalt tank heating of the heat transfer oil could smooth return to the heat transfer oil boiler and generally appropriated heat conduction oil pressure.For the whole pipeline pressure drop was calculated,and the friction of pipe and partial friction had carried on the detailed discussion and calculation,and the total pressure dropped along the pipeline.Through the relevant data to calculate the flow rate of heat conduction oil,the pressure centrifugal pump selection scheme of ascension was selected.更多还原
