最近,国家质检总局对增 氧机产品质量进行了国家监督 抽查,发现增氧机质量较为突 出的问题是“增氧能力”、 “动 力效率”和“空运转噪声”。 目前,我国水产养殖业已 普遍推广高密度机械化养殖技 术,在水产养殖机械化设备中, 增氧机是其中的关键设备,它 是一种通过电动机或柴油机等 动力源驱动工作部件,使水和 空气充分混合,从而扩大气液 接触面积,使空气中的“氧” 迅速转移到养殖水体中的设备, 主要有叶轮式、水车式和射流 式等形式。其中叶轮式增氧机 Recently, AQSIQ carried out a national supervision spot check on the quality of aerator products and found that the problems with more prominent aerator quality are “aerobic capacity”, “power efficiency”, and “air-to-noise” . At present, the aquaculture industry in our country has popularized the technology of high-density mechanized aquaculture. Among the aquaculture mechanization equipment, the aerator is the key equipment among them. It is a kind of technology which drives the working components through the power source such as a motor or a diesel engine to make the water and the air fully Mixing, thereby expanding the gas-liquid contact area, so that the air “oxygen” quickly transferred to aquaculture water equipment, mainly impeller, waterwheel and jet and other forms. Which impeller aerator
