The Third Generation of Fishery Aerator: Cost Reduction of 50% Fishery More Environmentally Friendly

        (China Fishery News, March 11th, 2025) Under the guidance of the policy of "Several Opinions on Accelerating the Green Development of Aquaculture" issued by the Ministry of Agriculture and Rural Affairs, the mechanization rate of aquaculture in China has exceeded 65%, but the efficiency bottleneck of traditional fishery oxygen-increasing equipment continues to restrict industrial upgrading.As a national high-tech enterprise, the R&D team of Shangqi Group has gone through 24 months of technical difficulties and integrated various resources in Industry-University-Research. According to the person in charge of the project, the team has traveled all over 23 key aquaculture areas in China. After collecting and analyzing 150,000 groups of water data, the design concept of "accurately matching aquaculture needs" was innovatively put forward.

        This product integrates the achievements of Jiangsu University's "Optimization of Ecological Aquaculture System" and successfully breaks through the application barrier of permanent magnet synchronous drive technology in aquatic products field.After two years of research and development, Jiangsu Shangqi Group and Jiangsu University Fisheries Research Institute jointly researched and developed, and the third generation permanent magnet synchronous fish pond aerator was officially put on the market.

This product embodies the innovative power of Industry-University-Research's deep integration, and takes "accurately matching the breeding needs" as the core goal, achieving a double leap in technical performance and user experience. The models of Shangqi permanent magnet synchronous aerator are waterwheel SQS-1.5KW, impeller SQY-1.5KW, impeller SQY-2.2kw and impeller SQY3KW, which can meet all kinds of aquaculture.

         Aiming at the pain points of traditional fish pond aerator, such as high energy consumption, complex maintenance and insufficient running water depth, the team went deep into the national aquaculture base for investigation, and combined with the ecological aquaculture research results of Jiangsu University Fisheries Research Institute, put forward the concept of "non-redundant design".

           Technical iteration: the first two generations of products have invested more than 1,000 groups of comparative tests, optimized the magnetic circuit structure of the motor and the hydrodynamic model of the impeller, and finally broke through the stability bottleneck of the permanent magnet synchronous technology.The innovation of permanent magnet synchronous pond aerator has three designs: eliminating vulnerable parts such as gears, gearboxes and controllers to realize "zero oil and zero mechanical wear" operation; Modular assembly: support rapid disassembly and reduce transportation and installation costs.

            The depth of running water is 3m: Through bionic optimization of impeller, a three-dimensional circulating water flow is formed, effectively covering the deep-water aquaculture area. Compared with the traditional model, it saves energy by 30%-45% and reduces the annual operating cost by over 50%. The efficiency of permanent magnet motor reaches 96%, and the motor will not burn or burn after long-term use.At the intersection of the national "double carbon" strategy and the rural revitalization policy, the third generation of permanent magnet synchronous fish pond aerator is on the market, which indicates that China fishery equipment manufacturing industry has entered a new stage of value creation.

          According to the latest data of china aquatic products processing and marketing association, the comprehensive output value of aquaculture in China exceeded 2.8 trillion yuan in 2024, and the demand for equipment upgrading continued to be released. The technical breakthrough of Shangqi Group not only solved the "bottleneck" problem of traditional equipment, but also built a complete technical closed loop from core component research and development to system solution.
