Discussion on the Measurement of Hatch Median Point for the Nuclear Reactor in Nuclear Power Station
Zhang Guangqing · Power Station Auxiliary Equipment · 2008
Hatch is an important equipment in the containment of reactor in nuclear power station.The hatch must keep verticly in the process of opening and closing.Therefore,it is one of key technologies to ensure the hatch median point for 2 lifting lugs fixed so as to make the plane consisting of lug hole center and whole hatch median point verticly to the ground and parallel to the sealing surface of the hatch.The center of lug hole has been found with a hanging piece based on the principle of that an extended line from free hanging point shall pass through the median point of a substance,so as to solve the problem of the determination for large,irregular substance in suspension status.
