中文摘要：SAN装置聚合釜搅拌器由于工艺特性需定期更换机械密封，原有搅拌器结构更换机械密封时需连带支架整体吊装翻转后进行更换，改造后可实现不拆卸搅拌器与罐体联接的大盖法兰，不需要将轴抽出就可以更换机械密封的目的，大大降低检修安全风险，提高检修效率。
英文摘要：The agitator of SAN plant-polymerizer needs to replace the mechanical seal regularly, When the mechanical seal is replaced,it needs to lift and flip the original agitator with the bracket.After the transformation,there is no need to disassembly the connecting flange of the agitator and the polymerizer tank ,and no need to pull out the shaft.Then the risk is greatly reduced and the efficiency is improved during the overhaul.
