摘要 PTA精制单元结晶器搅拌器BA601、BA602、BA603机封缓冲液系统原设计采用甘油自动补偿系统,但后来频频出现故障,对搅拌器机封的寿命及装置的正常生产带来了严重影响。为此,将结晶器搅拌器机封缓冲液由甘油改为脱离子水,截至目前为止,使用情况十分良好。 The crystallizer agitators BA602, BA601, BA603 of PTA plant refining unit, originally was designed with glycerol automatic compensation system, but then frequently appeared failure, which caused serious impact on the life of the mechanical seal and the normal operation of the device. In view of the problems existing in the system, the workshop changed the mechanical seal buffer of the crystallizer agitators from glycerol to deionized water, up to now, the usage is very good.
