| Abstract: | 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. |
