轮库复线的实际年输量远低于其设计输量,输油泵所做无用功的能耗较高。为了提高整个管道系统的效率,降低输油单耗,从1999年开始陆续对轮南原油站5台八级输油主泵分别进行了拆级改造,以实现节能和优化运行。输油泵拆级改造结果表明,通过优化运行方式,选择适当的泵组合方式,在保证外输能力的同时节能降耗效果明显,提高了管道运行效率。 The actual annual output of the round-trip multi-line is much lower than the designed output, and the energy consumption of the unused work by the oil pump is high. In order to improve the efficiency of the whole pipeline system and reduce the unit consumption of oil transmission, the dismantling and upgrading of five main oil pumps of level 8 in Lunnan crude oil station were carried out respectively from 1999 to achieve energy saving and optimized operation. The results of demolition and upgrading of the oil pump show that by optimizing the operation mode and selecting the appropriate pump combination, the energy saving and consumption reduction effect is obvious while ensuring the capacity of transportation and the operation efficiency of the pipeline is improved.
