变频调速技术在某成品油管道的应用李欣泽
2013 10 32 10 1000-8241 2013 10-1134-04 257026 TE832A doi 10.6047/j.issn.1000-8241.2013.10.022 Application of frequency control technique in a product oil pipeline Li Xinze, Yan Wei, Liu Jianwu Shengli Engineering Consulting Co. Ltd., Dongying, Shandong, 257026 Abstract: In order to avoid the energy loss caused by traditional frequency constant speed motor, applying the frequency control technique to pump unit can meet the requirement of pipeline operation at low transportation capacity and reach the aim of energy saving. The paper describes the principle of frequency control in detail. Taking the actual oil product pipeline as an example, SPS simulation software is employed to simulate the working condition of fi xed speed pump and variable speed pump which uses frequency control technique under different transportation capacity. The energy saving effect before and after installation of frequency control device is compared, and furthermore the economic benefi t brought by application of frequency control technique to oil pump is evaluated. It is pointed out that the accuracy of simulation results will be lowered if the accurate throttle valve curve and the characteristic curve of pump under multiple rotating speed are absent in the input parameters.(5 Figures, 5 References) Key words: oil pipeline, oil pump, frequency control technique, SPS simulation software, energy saving
