摘要
涡流增氧机是解决越冬鱼池增氧的专用设备，结构新颖，体积小，工效高，且制造简单、操作容易。由于采用涡流原理，叶轮工作时能自吸由外界大气中直接补氧。被吸空气经机内加热，呈温暖之细气泡进入水体，可达到增氧和避免水温下降的双重效果。
The vortex eddy aerator provided for aeration of frozen fishponds and the Lake. It 's new in structure,small in size,high efficieney,easy to handle and maunfacutre. It not only pul is atmospherie air but also mixes water When atmospherie air is pulled down the hollow shaft, the air passes through a heater and enters the water as fine bubbles which are thoroughly mixed into the pond water by turbulence created by turbine, and mixing prevented thermal stratification.After it wag tested with 2.2kw motor the oxygen transferred 2. 15kgO2/kw·h,the flow of air 45 to 60m3/h.The article systematiclly describles the principle of operatin and the calculation in design.Specially it details the design of principle in tEe sealing system
