Automatic Video Inspection System for Bolting Thread of Reactor Pressure container
Application and performances:
The equipment is suitable for auto-detection of thread surface defects in the bolting holes of the reactor pressure container by displaying video image. It can store digital image, and offer high-definition color images and data of each thread surface, which are regarded as the reference of maintenance and repairing. It can be also applied in auto-detection of deep hole surface under venomous environment. The equipment consists of a robot suitable for working in radiation range and a control cabinet. The robot and control cabinet are connected by a 30-m cable .
Main technical specifications:
①Automatic inspection of bolt hole according to preset procedure or carry out manual operation of inspection at arbitrarily bolt hole, the system can reduce the radiation damages to personnel.
②The robot has an ability of automatic positioning of the hole to be detected and manual positioning can also be implemented.
③The system has a barrier protection unit and a light-alarm device
④Capable of displaying with pictures and data and digital storage.
⑤Capable of detecting bolt hole diameter : Φ130~180mm.
⑥Capable of detecting bolt hole depth: ≤ 270mm (modification based on consumer’s need).
⑦Detectable pitch of screw thread: T=4*MM.
⑧Scanning velocity: multiple options.
⑨Environment: Temperature 0ºC~50ºC, relative humidity 95%, γ dosage rate 102rad/h, power AC 220V, 50Hz.
(At present, there are two sets to be used in Daya Bay/Ling Ao Nuclear Power Plant, and one set in Qinshan Nuclear Power Plant, phase II.)
