[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.
