聚丙烯反应器循环泵密封失效分析及改进

SEALING FAILURE CAUSE ANALYSIS AND RETROFIT MEASURES FOR CIRCULATING PUMP IN POLYPROPYLENE REACTOR

针对聚丙烯装置环管反应器循环泵密封频繁故障导致装置停工的问题,重点分析了循环泵机械密封故障失效原因,并根据分析结果具体实施相应改进措施,对密封系统进行了技术改造,保障了循环泵的长期高效运行。

Aimed at the device shutdown problem tion pump seal in tubular loop reactor of the polypropy the circulation pump seal were analyzed in detail. Base caused by frequent failure on the eireula- lene device, the causes for the failure of d on the analysis results, the cotrespond- ing modification measures were executed. Technological revamp was made in the seal system, the long term and high efficient running of the circulating pump was ensured.
