Water wheel aerator as the same name as impeller aerator aquatic feeding equipment, has its own characteristics and scope of use, water wheel aerator by the motor as the power, through the reducer to reduce the speed, drive the impeller to turn. During operation, the blades on the impeller are partially or completely immersed in water. Below, take a look at the use of water wheel type aerator status and characteristics.

In the process of aquatic feeding, there will be bait impurities and fish and shrimp excrement in the water to form a certain bottom, the bottom for the growth of fish and shrimp have their own interests, the appearance and use of aerator is to reduce the disadvantage, increase the help for the growth of fish and shrimp. It is a common and effective way to improve the water quality of shrimp ponds by using aerator. The commonly used aerators include turbine aerator and water wheel impeller, etc. Although the structure and methods are different, the purpose is the same. By mechanical means, the oxygen-deficient water can be added with dissolved oxygen to provide a favorable living environment for prawns and other organisms. There are two kinds of impeller type and water wheel type in common use, and the use of water wheel type aerator is becoming more and more common in southern China.

The operating principle of the water-wheel aerator is that the water-wheel aerator impacts the water through the blades. On the one hand, the lower water is raised until the water is broken into splashes and thrown into the atmosphere. After increasing the dissolved oxygen, it falls back to the pool water by gravity. On the other hand, it promotes the water movement of the pond to form a circulation, which can transport the water body with enough dissolved oxygen to all parts of the shrimp pond to form a relatively uniform dissolved oxygen distribution.

The characteristic of the water wheel aerator is that the pool water forms a circulation, so that the DO value of the whole pool tends to be the same within a certain time. The formation and maintenance of circulation requires a certain amount of energy, which is determined by the viscous nature of water. The activities of the pool water are complex. The main stream is a circulation, and backflow will be generated when it turns out. There is no existing model for this kind of activities. Circulation promoted the distribution of DO, and its pressure distribution was beneficial to the realization of sewage collection in the center of shrimp pond. In practice, the problems encountered can be summarized as: the influence of the placement method of the aerator on the aeration effect, and the influence of the placement method of the aerator on the central pollution collection effect: both of these two problems are closely related to the circulation of the shrimp pond.

In some news reports, the yellow impeller on the new device's water-wheel aerator quickly turns over, stirring up a strong splash that accelerates the dissolution of oxygen in the air into the water. According to the introduction, this novel aerator is composed of motor, reducer, frame, buoy, impeller, etc., which is suitable for aerating shallow water feeding ponds with a depth of 1 meter. More and more crab ponds or shrimp ponds are using this machine to aerate.
