Jet type submersible aerator QSB1.5

Jet type submersible aerator QSB1.5

The principle of QSB1.5 jet aerator:
Under the high-speed rotation of the pump impeller, the liquid is sprayed out from the nozzle at a high speed. When the high-speed flowing liquid passes through the mixing chamber, a vacuum is formed in the mixing chamber, and a large amount of air is sucked in through the air duct. After entering the mixing chamber, the air vigorously mixes with the liquid at the throat, forming a gas-liquid mixture, which is discharged through the diffusion tube. The air rises in the water as fine bubbles, forming efficient material transfer throughout the process.


Jet type submersible aerator QSB1.5Performance characteristics:
1. Compact structure, small footprint, easy installation.
The layout, diving depth, and number of units to be used can be flexibly selected based on the characteristics of the aeration tank, the size of the sewage treatment capacity, and the indicators of the incoming sewage.
2. High aeration efficiency and wide application range.
Due to its high-speed jet flow state, thorough mixing of liquid and gas, high oxygen absorption rate, and high power efficiency. Higher treatment efficiency than traditional aeration tanks3-4 times, the aeration time can be significantly shortened, and it is suitable for various sewage treatments, including push flow aeration tanks, mixed aeration tanks, delayed aeration tanks, oxidation ditches, oxidation ponds, etc.
3. The system is simple, unobstructed, and highly reliable.
from
Submersible pumpIt is composed of a spray nozzle, which allows for simultaneous agitation and oxygenation of the water body, resulting in fine bubbles and a high oxygen transfer rate. It also has the advantages of unobstructed impeller. Strong unidirectional fluid flow, resulting in effective convection
Cycle, and the motor load changes very little with the water level. No need for blowers or other equipment, the system is simple, except for the suction port, the rest of the parts are submerged in water for operation, with low noise and safe and reliable equipment.
4. Low investment and operating costs.
Due to its suitability for deeper aeration tanks, the jet aerator reduces the footprint, simplifies the system, saves investment costs, has high treatment efficiency, and saves operating costs.
5. The jet injector is made of all stainless steel, which is corrosion-resistant and durable.

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.

The submersible jet aerator using three-phase power supply should be checked for rotation direction after initial start-up or each reinstallation. Incorrect rotation direction can reduce efficiency and damage the water pump.

The inspection method is: Before the final installation of the submersible aerator, look up at the suction port of the submersible aerator from the bottom and rotate the impeller counterclockwise. If several submersible aerators are connected to a controller, each aerator must be inspected separately. If the rotation direction is incorrect, the position of any two of the three-phase wires on the controller can be exchanged to change the rotation direction

Jet type submersible aerator QSB1.5Adopting unique hydraulic component design, optimizing the clearance between the impeller and guide vanes (less than)1mm）， Compared to older models of aerators, the gap between the impeller and guide vanes (greater than 5mm) is much smaller
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.
