What are the main structural composition and functional characteristics of the impeller aerator

The main structure of the impeller aerator is composed of a motor, a reduction box, an impeller, a support rod, and a float. As far as the impeller is concerned, it is divided into inverted umbrella impeller and deep water impeller. The impeller aerator has the functions of stirring, aeration, mixing and aeration. These functions are performed simultaneously while the machine is running. In addition to aeration, the aerator also has the functions of stirring water and aeration to promote the growth and reproduction of phytoplankton and improve the primary productivity of the pond. The mechanical structure is relatively simple, mechanical failures rarely occur during use, maintenance is relatively convenient, and maintenance costs are reduced.

The impeller aerator uses mechanical methods to increase oxygen. The motor drives the water surface impeller to agitate the water surface, stir the gas film and liquid film, increase the contact area of ​​gas and liquid, expand the concentration gradient of oxygen in the water, and increase the oxygen in the air. The speed of transfer and diffusion into the water.

The impeller type aerator is mainly composed of a motor, a reduction box, a surface impeller and a floating ball. It has developed a product series today, including 7.5kw, 5.5kw, 3.0kw, 1.5kw, 1.1kw, 0.75kw model. Two impeller aerators of 3.0kw and 1.5kw are commonly used.

The aeration effect of the impeller type aerator equipment is very obvious. By using the impeller type aerator, an oxygen-enriched ring with a radius of about 10 meters centered on the aerator can be formed in the water body. In the pond test, the impeller-type aerator was operated for about 80 minutes to keep the dissolved oxygen content and water temperature of the water at a depth of 1.5 meters consistent with the upper water. The impeller aerator has high power and high efficiency, and can increase oxygen by more than 1800 grams per kilowatt/hour. When the pond water is rich in oxygen, it can effectively inhibit the occurrence of bacterial and viral diseases in aquaculture, which is of great significance for increasing production and income of aquaculture.
