Two categories of submersible aerators

According to the different principle and application of submersible aerator, it can be divided into two types: submersible jet aerator and submersible centrifugal aerator The submersible aerator is used for aeration and agitation of the aeration tank and the aeration grit chamber of the sewage treatment plant, oxygenation and mixing of the mixed liquid of sewage sludge, biochemical treatment of sewage, breeding oxygenation and landscape water maintenance In addition, the submersible jet aerator can also be used in the front section of the self water process, in addition to iron and manganese processes, and in the water make-up circulation process of high-rise buildings Medium Principle of centrifugal aerator: the submersible centrifugal aerator is directly driven by the motor and impeller The centrifugal force generated by the rotation of the impeller is used to drain the surrounding water to form a low-pressure suction water flow At the same time, a vacuum is created at the inlet of the impeller and air is drawn in In the air mixing chamber, air and water are mixed to form a uniform air-water mixture, which is quickly discharged under the effect of centrifugal force Because the water jet is very strong, it causes effective water circulation and makes the air be cut into a large number of tiny bubbles The surface area of the aerator is greatly increased, and a large amount of oxygen in the air is dissolved in the water due to the slow rise of bubbles, which makes the power efficiency of the aerator better than other kinds of aerators Principle of jet aerator The water produced by the submersible jet aerator through the submersible pump flows through the nozzle to form a high-speed water flow, forms a negative pressure around the nozzle to draw in air, mixes with the water flow through the mixing chamber, and generates a water gas mixed flow in the trumpet shaped diffusion tube, which is ejected at a high speed The water flow with many bubbles is swirled and stirred in a large area and depth of water, completing the aeration, and its axial power is not With the change of submergence depth, the air intake can be adjusted.
