变频调速技术在催化裂化装置机泵中的应用

Application of frequency timing technique in pump of the fluid catalytic cracking unit

简要介绍了变频调速技术,重点分析了与阀门调节相比,变频调速器的节能效果,比较了变频调速器应用前后机泵的运行周期和采用阀门调节与变频调速调节两种方式的节能效益,同时分析了控制方案的不同对节能效果的影响.

This paper briefly introduced frequency timing technique, played emphases on the analysis of energysaving effect of frequency timing appliances contracted to that of control valve regulation, and compared the run cycle of the pump before applying these appliances with that after doing them, also did the energy-saving benefit adopting control valve regulation with that doing frequency timing regulation. In addition, it analyzed the influence of different control schemes upon the energy-saving effect.
