QXB centrifugal submersible aerator

The QXB submersible aerator adopts a unique hydraulic component design, optimizing the gap between the impeller and the guide vane (less than 1mm), which is much smaller than the gap between the impeller and the guide vane of the old model aerator (greater than 5mm). In addition, the unique star shaped impeller design and radial water and air mixing channel generate centrifugal force in the water under the drive of the high-speed rotating motor. Under the action of centrifugal force, a negative pressure zone is formed around the impeller, and air is sucked in through the intake pipe. The air and water are torn apart by the high-speed rotating impeller in the mixing chamber, and the gas-liquid turbulence mixes and exits through the diffusion channel at high speed, forming bubbles that dissolve oxygen in the air into the water. Due to the strong jet of water and the star shaped impeller cutting the air bubbles finer, smaller, and denser, the contact area between the air bubbles and the liquid to be treated is larger. The air is sheared into a large number of tiny bubbles, greatly increasing the mass transfer area and forming a spiral shaped effective water flow cycle. A large amount of oxygen is dissolved in the water and has a very high oxygen utilization rate.
