Product details
General
Submersible centrifugal aerators are normally used in aeration tank, aeration & degritting tank for oxygen transfer, mixing and biochemical treatment of sewage / wastewater, or used in aquaculture pond for oxygen transfer.
Working Principle
QXB series submersible centrifugal aerator is a direct connection aerator and has a compact design. The impeller rotates and generates a centrifugal force, as a result a negative pressure zone will be formed around impeller, the air will be sucked in through air inlet pipe and mixed with water in the mixing pan, and soon the evenly mixed water-air mixture will be sprayed out through outlet.
A few aspects exist in this process: air-liquid mixing effect is generated when air and water are mixed in mixing pan; discharged air-water mixture will form recirculation and convection; large amount of oxygen molecules in sucked air move in high velocity; all these factors makes a quite high oxygen absorption efficiency.
Key Features
- Tiny air bubbles take a big portion in the air-water mixture, it causes a high oxygen dissolution efficiency and large oxygenation area.
- No dead zone, the aerated horizontal water flow entrained with tiny bubbles will scour every corner of the aeration tank.
- Simple and compact design, heavy duty bearings, long lifetime.
- Oil-bath type shaft seal, and the inhaled air in impeller chamber will prevent water from contacting the sealed parts.
- Capable of 24 hours continuous running for long time with very low failure rate.
- Cost saving, no need to have blower for air supply.
- Easy installation, operation and maintenance.
- Low noise
