Zhangzhou first phase of the nuclear power use "hualong" number one nuclear power technology, every units, a total of three sets of main pump pump shell, each loop has a main pump pump shell, the pump is the core of the nuclear power plant nuclear time road system, is the only high speed rotating equipment in nuclear island, its main function is to provide power for coolant loop, the safety of the nuclear reactor operation plays an important role. The pump shell of the first main pump was lifted from the top of the reactor building into the main pump room by a 650-ton crawler crane.
To ensure the smooth lifting, introducing the main pump pump shell from zhangzhou zhangzhou nuclear power project construction management team nuclear power unit 1 pump casing lifting and installation experience, compared with traditional construction method, using 3 d laser measurement technology innovation, improve the machining precision of the leg adjustment with plate, in front of the main pump shell assembly to realize a plate processing molding, to avoid the secondary lifting pump shell, The construction period is optimized and the occupation of crane resources is reduced. The project team took practical actions to promote the introduction of main equipment of Unit 2, constantly promoting the high-quality development of Zhangzhou Nuclear power project construction, and laying an important foundation for the next step of main pipeline welding.
