Rotary impeller aerator is mainly composed of motor, reducer, the water impeller and floating ball, it increases oxygen by mechanical method, through the motor driving the water impeller rotation to stir the water, mixing gas membrane and liquid membrane, increase the contact area of gas and liquid, to enlarge the concentration gradient of oxygen in the water, increase the oxygen in air to the water transfer rate of diffusion.

After the impeller aerator starts, the impeller sucks up the oxygen-poor water at its lower part, and then pushes it around, so that the stagnant water becomes the living water. The water under the impeller is strongly stirred by the blades and pipes, and the water jumps and waves are aroused on the water surface to form a water curtain that can be wrapped in the air. It not only expands the surface area of the gas-liquid interface, but also the double membrane between the gas and the liquid becomes thin and constantly updated to promote the dissolution rate of oxygen in the air.

What functions does impeller aerator have

1, increase oxygen

Impeller aerator has high power and high efficiency. It can increase oxygen by more than 1800 grams per kilowatt/hour. Under the condition of enriched oxygen, pond water can effectively inhibit bacterial and viral diseases in aquaculture, which is of great significance to increase production and income of aquaculture.

2, water,

The impeller aerator can enhance the bottom water and make it alternate with the surface water, thus having the effect of oxygenating to the bottom water. The oxygenating depth is more than 2 meters, which is conducive to breaking the vertical uniformity of dissolved oxygen in the pool water and giving full play to the oxygenating effect. Therefore, it is suitable for high-yield deep water fish ponds.

3. Exposing harmful gases

The impeller aerator has strong aeration power, and the harmful gases such as ammonia, hydrogen sulfide, methane and carbon monoxide in the pool water can be effectively aerated.

4, water efficiency

Impeller aerator can also increase the efficiency of freshwater aquaculture water body, thus improving the quality of aquaculture water body, can quickly remove the fish, shrimp hypoxic floating head, break the pool water stratification, improve the primary productivity of the pond, improve the density of aquaculture, improve the yield, reduce the feed coefficient.

Use skills of impeller aerator

1. Turn on the machine in sunny afternoon

The aeration of aquaculture water mainly depends on photosynthesis. Afternoon is the time of day when there is the most light and photosynthesis of phytoplankton in the water is the most active time. As a result of photosynthesis in the deepest waters can only achieve two times the depth of water is transparent, the surface of the pond water dissolved oxygen to super saturated, in, at the bottom of the water body is still in the less oxygen, would then the impeller type aerator of mixing and exposure can qigong, the top layer of super saturation dissolved oxygen in the water to the bottom, the underlying owe oxygen in the water to the upper for photosynthesis, At the same time, the harmful gases at the bottom of the pond, such as ammonia, hydrogen sulfide, methane, carbon monoxide, etc., are brought to the surface of the water, so that the overall dissolved oxygen level of the fish pond is improved, and the harmful substances in the water are reduced.

2, early morning boot

Early morning in the pond water dissolved oxygen is the lowest time of day, especially in high-density aquaculture ponds, dissolved oxygen in the water is less than 2 mg/l, fish often float at this time. When the aerator is turned on at this time, a relatively oxygen-rich zone can be formed around the aerator to prevent the occurrence of floating head and pond overturning accidents.

3. When it's rainy

Since the photosynthetic capacity of the water in the fish pond is poor, the oxygenation of the aerator is mainly used to maintain the dissolved oxygen of the water in the fish pond, the start-up time should be increased. The farmers can control the start-up time according to the water temperature, and the start-up time should be increased if the water temperature is high.

Plum rain season

Due to the low pressure, the oxygen in the air is difficult to dissolve into the water. At this time, the oxygenation efficiency of the aerator is also the lowest. It is better to turn on the aerator 24 hours a day to prevent the water from being anoxic and turning over the pond.
