延迟焦化富气压缩机变频调速技术

介绍了南京炼油厂变频调速技术用于焦化富气离心压缩机高压电动机系统的情况。生产实践表明，该技术调速范围在80％～100％，能适应焦化富气量变化大的要求，实现平稳操作，达到节电的目的，3～4年内可回收技改投资。

FREQUENCY GOVERNING TECHNIQUE FOR DELAYED COKER RICH GAS COMPRESSOR

The application of frequency governing technique in high voltage motor system of centrifugal compres sor for coker rich oil gas was introduced. Operating practice indicated that, in 80% ~100% of the governing frequency range this technique can accommodate to the great variation in coker gas quantity, realizing smooth opera tion and attaining electricity-saving. The investment of technical innovation can be return in 3~4 years.
