The depth of fish pond water is different, the density of fish culture is different, and the oxygen aerator to be equipped is also different. In order to achieve the goal of high yield and high efficiency, five types of aerators are introduced for local farmers to purchase according to actual needs.
I. Impeller aerator The machine increases the dissolved oxygen content in the water by stirring the water body and the aeration principle. It has good oxygenation effect and high power efficiency. There are various types of motor power. When used, the whole machine floats in the middle of the pond and is fastened to the pool with ropes. When working, the impeller rotates, stirs the water body, produces the lifting water and promotes the mixing of the water body, causes the water layer to produce the convection up and down, the dissolved oxygen of the entire water body tends to be balanced. General requirements pool depth 1.5 to 2 meters.
Second, the waterwheel type aerator When the machine is working, the blade hits the water at high speed and stirs the air into the water to achieve oxygenation. This aerator is suitable for shallow ponds, it will not stir the sediment and keep the pool cool.
Third, the water-type aerator This machine uses the water pump to send the water to the sprayer installed in the middle and shore of the fish pond, so that the water is sprayed and rain falls, so that the contact of water and air to increase the purpose of dissolved oxygen. This machine is only suitable for shallow fish ponds.
Fourth, jet aerator This aerator is composed of submersible pump and jet tube. When working, the water in the water pump is ejected from the nozzle in the tube at high speed to generate negative pressure and suck in air. The water and gas are mixed in the mixing chamber and then pushed out by the diffusion tube. Dissolved oxygen diffuses with the water in a straight line. Since this aerator will not harm the fish, it is suitable for deep-water ponds with high fish density.
Fifth, the main body of the inflatable aerator is an air compressor or a blower. When the air is pressurized and passes through a sand filter or a microporous plastic tube installed on the bottom of the water, tiny bubbles are discharged. During the rising of the bubbles, part of the oxygen dissolves into the water to form water bodies. The machine is suitable for deep-water fish ponds.
