【摘要】：對核電站現(xiàn)有循環(huán)水泵的密封氣囊結(jié)構(gòu)進行了分析,現(xiàn)有密封氣囊接口需通過專用工具采用密封膠進行粘合,以達到氣囊密封要求。該工藝對現(xiàn)場操作人員的熟練程度提出較高要求,存在粘接難度大、易失效等風險。通過對原有密封氣囊接頭進行重新設(shè)計:(1)將原來的開口式結(jié)構(gòu)變?yōu)閮蓚?cè)封閉式結(jié)構(gòu),保證了氣囊內(nèi)部氣壓的維持和穩(wěn)定;(2)接口對接形式由原來的直接對接變更為插入式,通過調(diào)整氣囊接口處的插入深度達到現(xiàn)場安裝要求。新型氣囊更換方便、性能可靠,為設(shè)備安全運行提供了有力保障。
[Abstract]:The airbag structure of circulating water pump in nuclear power station is analyzed. The existing airbag interface needs to be bonded with sealant through special tools in order to meet the requirements of airbag sealing. The process puts forward higher requirements for the proficiency of field operators, and there are some risks such as high bonding difficulty and easy failure. The original airbag joint was redesigned: (1) the original open structure was changed into the closed structure on both sides to ensure the maintenance and stability of the air pressure inside the airbag; (2) the interface docking form is changed from the original direct docking to the plug-in, and the insertion depth of the air bag joint can meet the field installation requirements by adjusting the insertion depth of the air bag joint. The new airbag is easy to replace and reliable in performance, which provides a strong guarantee for the safe operation of the equipment.
