Domestic professional integration supplier of shock absorption, anti vibration and support products.

National high-tech enterprise integrating design, manufacturing, testing and full life cycle service

Changzhou Green Power Machinery Manufacturing Co., Ltd. was established in October 2002, the company is located in Changzhou, Jiangsu Province, with a registered capital of RMB 85.18 million. Since its inception, the company has specialized in the design, manufacture and overhaul services of nuclear-grade hydraulic dampers, and is the first high-tech enterprise in China with the full series of nuclear-grade hydraulic dampers manufacturing and design qualification issued by the State Nuclear Safety Administration. The company's nuclear grade large hydraulic damper products in the national market share of more than 50%, ranking No. 1 in China; nuclear grade damper test bench overhaul business covers all domestic units in service, products directly supporting China Nuclear Power Engineering Co. The company has formed long-term and stable cooperation relationship with these enterprises in joint research and development and product supply. The company fully integrates the upstream and downstream resources of the industry, and is a member of China Nuclear Energy Association and China Experimental Fast Reactor Industrialization Alliance.

The company independently researched and produced large nuclear grade hydraulic dampers for the next generation of nuclear power plant main equipment support equipment, the product maximum damping force (load capacity) 10000kN, is the AP1000, CAP1400, Hualong 1 and other representatives of the next generation of nuclear power units nuclear safety Ⅰ important equipment, is the State Nuclear Safety Administration requires mandatory licensing of nuclear power plants one of the important equipment. The product adopts the overall fully symmetrical closed structure design, independent detachable integrated valve group, accurate adjustable stiffness (±10%), with large load capacity, accurate damping stiffness and other characteristics, the performance indicators reach the international advanced level, replacing imported products such as Germany LISEGA, France Quiri, solving the long-term dependence on imports of "stuck neck The product has been appraised by the China Machinery Federation and has been certified by the latter as a "good quality" product. The product was appraised by the China Machinery Federation as "internationally advanced, domestic gaps", filling the gaps in the country and making up for the shortcomings of the whole industry. The product was recognized as the first (set) major equipment product of Jiangsu Province, won the third prize of the China Machinery Industry Science and Technology Award, and was listed as a national key new product.

 

The company's innovative development of the international unique large capacity damper special test stand, static performance testing capacity of 12,800kN, dynamic performance testing capacity of 5000kN/5Hz, 1000kN/33Hz, to meet the comprehensive testing, verification of product performance index requirements, to ensure the safe operation of key equipment in the nuclear island. The products have been appraised by the China Machinery Federation as "internationally leading and unique", and have been recognized as the first (set of) major equipment products in Jiangsu Province, the third prize of Jiangsu Science and Technology Award, and the third prize of 2019 Shanghai Science and Technology Award for the first large hydraulic damper for nuclear power with a rated load of 5000kN in China. In addition, the company's advanced high-energy pipeline anti-dumping restraint dynamic performance test rig and simulation technology development project won the third prize of China Nuclear Energy Industry Association Science and Technology Award.

 

The company pays attention to R&D capacity building, with the proportion of R&D staff exceeding 30%, and has formed good joint R&D and university-enterprise cooperation with institutions and colleges such as China Atomic Energy Institute, Shanghai Nuclear Engineering Institute, Shanghai Jiaotong University and Hohai University, with an accumulative number of joint R&D projects exceeding 20. The company has authorized 9 core independent invention patents, including 2 high-value patents, and 20 utility model patents. The company has built Jiangsu Province Engineering Centre, Jiangsu Province Engineering Centre, Nuclear Power Plant Non-standard Tools and Equipment Engineering and Technology R&D Centre, Mechanical Comprehensive Test Centre and other R&D institutions.

 

In terms of management, the company operates in strict accordance with ISO9000 quality management system, ISO14000 environmental management system, OHSAS18000 occupational safety and health management system, GJB9001C-2017 national military standard quality management system and "Civilian Nuclear Safety Equipment Quality Assurance Outline", and has adopted EPR, OA, PLM and other information system construction, which effectively The company's production and operation efficiency has been improved.
