摘　　要：间苯二甲酸装置LMV-311型高速离心泵在使用过程中机械密封频繁发生泄漏失效,影响了正常生产。通过分析计算,找到泄漏原因,并对此进行改进,取得了明显的效果。The model of LMV -311 high speed centrifugal pump in Purified Iso -phthalic Acid plant leaks frequently during the process of use. It influences on the stable production. We found out the reason of leaking through analysis and calculation, and some improvement have been done. The operation hours are prolonged evidently.
