增氧机是池塘鱼类养殖的重要工具。使用增氧机可以提高鱼类产品的产量,防止因水体缺氧而造成鱼类的死亡,减少不必要的损失。传统增氧机主要有叶轮式、水车式、充气式和喷水式等几种,其中充气式增氧机主要用于鱼类运输及贮存时小容积水体的增氧。这些增氧机的共同特点是采用定点作业。它们的作业方式限制了增氧机的有效增氧面积。上述增氧机中,效率最高的是叶轮式增氧机, Aerator is an important tool for pond fish farming. The use of aerator can increase the production of fish products, prevent the death of fish caused by lack of oxygen and reduce unnecessary losses. Traditional aerator mainly impeller, waterwheel, inflatable and sprinkler several, of which inflatable aerator is mainly used for fish transport and storage of small volume of water oxygen. The common feature of these aerators is the use of fixed-point operations. Their mode of operation limits the aerator’s effective aerobic area. The above aerator, the most efficient impeller aerator,
