Recently, the nuclear power lifting equipment supplied by Henan Pegasus Crane for Zhejiang San'ao Nuclear Power Station was successfully delivered. This delivery is a milestone in the development history of Pegasus Crane and has been recognized by Zhejiang San'ao Nuclear Power Project. It also confirms the high quality, reliable design and performance of Pegasus Crane Nuclear Power Crane Equipment.

Project Background

Zhejiang Sanao Nuclear Power Project is located in Sanao Village, Xiaguan Town, Cangnan County, Wenzhou City, Zhejiang Province. It faces the sea on three sides and the mountain on one side. It plans to build 6 third-generation nuclear power technologies with China's independent intellectual property rights. It is the most important supporting project for Zhejiang Province to implement the "double carbon" strategic goal and build a national clean energy demonstration province. In the process of nuclear power plant construction, crane is an indispensable hoisting equipment, which requires higher requirements for crane equipment and is also a severe test for crane equipment manufacturers.

Project significance

After the completion of all six units of the San'ao nuclear power project, the annual power generation capacity can reach 52.5 billion kwh, which can reduce the consumption of standard coal by 15.88 million tons and carbon dioxide emissions by 43.68 million tons per year, which is equivalent to 118000 hectares of afforestation. it will provide a steady stream of clean energy for the sustainable development of the Yangtze River Delta region and make positive contributions to serving the national "double carbon" strategy.

In order to fully assist the strategic advancement of the San'ao Nuclear Power Station project, Pegasus Crane actively advised customers, analyzed the implementation of the strategy, analyzed the particularity of the driving requirements of the nuclear power station construction, and jointly discussed solutions.

Project Difficulties

Lifting equipment to play a better overall efficiency, the need for more professional, accurate design and process, but also need strong technical strength to do support.

The use environment is humid, the operation is strong, and the traditional lifting equipment standard requirements are very different, the need for lifting equipment better corrosion resistance, waterproof, stable performance and higher efficiency, more durable durability, higher safety factor.

Solution

Pegasus Lifting has never been afraid of difficulties. It is the spiritual inheritance of Pegasus for 30 years to forge ahead. Pegasus Lifting knows that this cooperation is of great significance. The quality, performance and matching degree of the crane are the key to the smooth delivery. Pegasus Lifting believes that good lifting equipment must be an amazing combination of precise calculation and reasonable design of precision craftsmanship.

For this reason, Pegasus has paid special attention to equipment requirements and often communicated with Sanao Nuclear Power Station until late at night, which laid an important foundation for the later technical team to carefully consider every detail and accurately calculate every parameter. From the selection of raw materials, product design, selection of accessories to the installation of the whole machine, Pegasus crane carefully treats every link, accurately controls, strengthens process and project management, strictly controls quality inspection and testing, and ensures the excellent quality and stable performance of the whole machine.

Compared with traditional lifting equipment, this project is much more difficult, which is a new challenge for Pegasus lifting designers.

Production and processing

Cut and blanking materials in strict accordance with the design, strictly set the welding sequence, and reduce welding deformation through reasonable welding sequence; After welding, vibration effect treatment shall be carried out to eliminate welding stress. The detection methods and instruments required by national standards shall be adopted for detection without sunshine, and the assembly process shall be carried out in accordance with the requirements.

Complete machine assembly: the staff must be familiar with the component construction drawing and relevant technical requirements, and review the quality of the parts to be assembled according to the construction drawing requirements; All components in the pre-assembly shall be sized according to the construction drawing, and the center of gravity line of each member shall meet at the node center and be completely in a free state, and no external force is allowed to fix.

Quality inspection and test of the whole machine: after the assembly of the whole machine is completed, strict quality inspection of the whole machine will be carried out, ranging from lifting trolley to weld screws, and the inspection will be carried out one by one. After the quality inspection of the whole machine is passed, the driving simulation test will be carried out. The lifting mechanism and the operating mechanism will perform repeated lifting, operation, parking, forward rotation, reverse rotation and other operations according to the working level to observe whether each operating mechanism is stable and whether each performance meets the design requirements. After the simulation test is free of problems, a qualified report will be issued.
