提升RH真空系统密封稳定性的实践与研究

Practice and Research on Improving Seal Stability of RH Vacuum System

RH真空系统在生产使用过程中,常会出现多个漏气点,影响RH真空度。针对此情况,根据现场生产实践经验,对RH真空系统中真空槽连接处密封、顶枪通道气囊密封、投料系统真空锁密封圈、真空泵主体及排污阀等易漏气点进行分析研究,并对其进行优化改进,解决了因漏气影响真空度差的问题,提高了RH真空系统密封稳定性,保障了生产顺稳进行。

During the production and use of RH vacuum system,multiple air leakage points often appear,affecting the RH vacuum degree.In view of this situation,according to the field production experience,the air leakage points such as the seal at the connection of vacuum tank,the air bag seal of top gun channel,the vacuum lock seal ring of feeding system,the main body of vacuum pump and blowdown valve in RH vacuum system are analyzed and improved,the problem of poor vacuum due to air leakage is solved,and the sealing stability of RH vacuum system is improved,ensuring the smooth and stable production.
