There are also many types of aerator products designed and produced according to the mechanism, their characteristics and working principles are also different, the oxygenation effect is quite different, and the scope of application is also different. demand, choose a suitable aerator to obtain good economic performance.

1) Impeller type aerator: It has the comprehensive functions of aeration, water stirring, and gas explosion. It is the most widely used aerator at present, with an annual output value of about 150,000 units. Its aeration capacity and power efficiency are superior to other machines. Type, but the operation noise is relatively large, generally used for large-area pond culture with a water depth of more than 1 meter.

2) Waterwheel type aerator: It has a good effect of increasing oxygen and promoting water flow, and is suitable for ponds with deep silt and an area of ​​1 000-2 540 square meters.

3) Jet type aerator: Its aeration power efficiency is higher than that of waterwheel type, inflatable type, water spray type and other forms of aerators. Its structure is simple, and it can form water flow and stir the water body. The jet oxygenation function can make the water body aerate smoothly without damaging the fish body, which is suitable for the use of oxygenation in the fry pond.

4) Water spray aerator: It has good oxygenation function, can rapidly increase the dissolved oxygen in the surface water in a short time, and also has artistic ornamental effect, which is suitable for fish ponds in gardens or tourist areas.

5) Inflatable aerator: the deeper the water, the better the effect, suitable for use in deep water.

6) Inhalation aerator: The air is sent into the water through negative pressure suction, and the water is mixed with the water to form a vortex to push the water forward, so the mixing force is strong. Its oxygen-enhancing ability to the lower water is stronger than that of the impeller aerator, and its oxygen-enhancing ability to the upper water is slightly inferior to that of the impeller aerator.

7) Eddy-flow aerator: It is mainly used for aeration of subglacial water in the north, with high aeration efficiency.

8) Oxygenation pump: Because of its lightness, easy operation and single oxygenation function, it is generally suitable for use in fry cultivation ponds or greenhouse cultivation ponds with a water depth of less than 0.7 meters and an area of ​​less than 0.6 mu.
