QSB0.75 jet roller aerator

Material of jet aerator:

The static seal of the submersible jet aerator adopts Dingqing-70 O-ring.

2..All fasteners of the submersible jet aerator are made of stainless steel.

3. The material of the intake pipe of the submersible jet aerator is galvanized.

4. The nozzle material is cast iron.

QSB0.75 submersible jet aeration adopts a unique hydraulic component design, optimizing the gap between the impeller and guide vanes (less than1mm), which is much smaller than the gap between the impeller and guide vanes of the old model aerator (greater than 5mm)
Combined with the unique star shaped impeller design and radial water air mixing channel, driven by a high-speed rotating motor, the impeller generates centrifugal force in the water, creating a negative pressure zone around the impeller. Air is drawn in through the intake pipe, and the air and water are torn apart by the high-speed rotating impeller in the mixing chamber. The gas-liquid turbulence mixes and flows out 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 surface between the air bubbles and the liquid to be treated becomes 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, resulting in extremely high oxygen utilization efficiency.

Nanjing Du'an Water Treatment Equipment Co., Ltd. has continuously introduced advanced technology and vigorously promoted technological innovation. Based on the first generation of submersible jet aerators developed, a new type of deep-water self-priming submersible jet aerator has been successfully developed. Nanjing Du'an Water TreatmentThrough systematic research, new design and testing methods have been summarized, which have enabled the overall performance of the product to reach the advanced level of similar foreign products and directly compete with foreign manufacturers in the market. The new deepwater self-priming submersible jet aerator has a compact structure, simple operation and maintenance, and convenient and fast installation. While maintaining its low-cost characteristics, its performance has been greatly improved. Without the need for compressed air, the submersible aeration depth can reach10mThe bubbles are finer, which increases the contact area between the air and the aeration medium, effectively improving the oxygen transfer rate. The matching non clogging submersible electric pump adopts the sealing technology of the submersible sewage pump used in the Three Gorges of the Yangtze River, greatly improving the reliability of the submersible jet aerator.

5Characteristics and Applications

The deep water self-priming submersible jet aerator agitates and oxygenates the water body simultaneously, with fine bubbles that can achieve high oxygen transfer rates and have the advantage of unobstructed impellers. The strong unidirectional liquid flow creates effective convective circulation, and the motor load changes very little with the water level, making it more suitable for application in pools with large water level changes. The maximum diving aeration depth can reach without the need for compressed air10mLow cost, easy to install and maintain. The main scope of application includes:

（1）Deep water aeration;

（2）Aeration and agitation of the biochemical tank;

（3）Sludge aeration and mixing;

（4）High concentration organic wastewater treatment process.
