讨论了热站效率、运输距离及管道承压能力等因素对不同输量热油管道运行经济性的影响。结果表明:热站效率对热力费用影响明显,但其影响程度与输量有关。运距变化对吨油公里运费影响较小,随运距增大,运费出现小幅下降态势。管道承压能力对运行经济性的影响比较复杂,较高的承压能力可以充分发挥泵扬程的作用,使动力费用降低,但并非承压能力越高经济性越好,与经济性有关的合适承压能力与站间距离、输量、泵型配置及泵运行方式密切相关。
The effects of thermal station efficiency, transport distance and pipeline pressure bearing capacity on the operating economics of different hot oil pipelines are discussed. The results show that the thermal station efficiency has a significant impact on the thermal cost, but the degree of influence is related to the output. The change of transportation distance has a small impact on the freight rate per tonne of oil kilometers, with the freight rate increasing slightly and the freight rate decreasing slightly. The influence of pipeline pressure bearing capacity on operation economy is rather complicated. Higher pressure bearing capacity can give full play to the function of pump head and reduce the power cost, but not the higher the pressure bearing capacity, the better economic efficiency and economy-related Pressure capacity and distance between stations, transmission, pump configuration and pump operation are closely related.
