| Abstract: | Based on the corrosion analysis of equipment in vacuum pumping system and the application effect evaluation of anti-corrosion measures,the combination of technological anti-corrosion and material upgrade is advanced as an effective method to prevent the equipment in the overhead vacuum pumping system in VDU in Karamay from corrosion.Since the material of atmospheric condenser,barometric discharge pipe,pump casing of follow-up water ring vacuum pump,impeller,and moisture tank was upgraded and anticorrosive paint was coated on the inner surface of pump casing,the equipment in vacuum pumping system has been well operated for two years. |
