Ordinary Discount Rake Bar Screen - Increase Oxygen Pump QXB Centrifugal Type Submersible Aerator – Holly Detail:
Products Description
The QXB submersible aerator is used in aeration tanks and aeration sedimentation tanks of sewage treatment plants to aerate and mix the mixture of sewage and sludge, and perform biochemical treatment of sewage or aeration in aquaculture ponds. The intake air volume is 35~320m3/h, the oxygen increase capacity is 1.8~24kg02/h, the motor power is 1.5~22kW.
Working Principle
Working Conditions
1. Medium Temperature: ≤40℃
2. PH: 5-9
3. Liquid Density:≤1150kg/m3
The structure of QXB submersible aerator is directly connected (Fig.A),the rotating impeller generates a centrifugal force in the water, and a negative pressure zone is formed around the impeller through the centrifugal force, so air is sucked in through the intake pipe, the sucked air and water are mixed in the aeration housing, and then this good uniform mixture is automatically discharged from the discharge port .
Products Features
1. Submersible motor directly drive, low noise, high efficiency.
2. Unique design for gas mixture chamber with big air intake volume.
3. Motor with double mechanical seal to ensure longer service life.
4. 12-20 rediated outlets, can bring a mass of bubbles.
5. Inlet with mesh, can avoid impeller being blocked by foreign material.
6. Guide rail available for easy installation&maintenance.
7. Stable operation with thermal protection&leakage sensor.
