River submersible centrifugal aerator

River submersible centrifugal aeratorBy using a motor and an impeller for direct transmission, the centrifugal force generated by the rotation of the impeller is used to expel surrounding water and create a low-pressure zone for sucking in water flow. At the same time, a vacuum is created at the inlet of the impeller to suck in air. In the mixing chamber, air and water are fully mixed to form a uniform mixture of air and water, which is quickly discharged under the action of centrifugal force.

Due to water jetstrongCreate effective water circulation, causing the air to be sheared into a large number of tiny bubbles. Greatly increasing its surface area, and due to the slow rise of bubbles, a large amount of oxygen in the air dissolves in water, making the power efficiency of this machine superior to other types of aerators.

Centrifugal aerators are used in aeration tanks and aeration sedimentation tanks of sewage treatment plants to oxygenate and mix the mixed liquid of sewage sludge, as well as to perform biochemical treatment or aquaculture oxygenation of sewage

River submersible centrifugal aeratorThe QXB centrifugal submersible aerator is directly driven by a motor and impeller. By utilizing the centrifugal force generated by the rotation of the impeller, the surrounding water is displaced to form a low-pressure zone and draw in water flow. At the same time, a vacuum is created at the inlet of the impeller and air is sucked in to fully mix the gas and water in the mixing chamber, forming a uniform steam water mixture that is quickly discharged under the action of centrifugal force.

Due to the strong jet of water, the effective circulation of water cuts the air into a large number of tiny bubbles. As the bubbles rise slowly, a large amount of oxygen in the air dissolves in the water, and the dynamic efficiency of the aerator is better than other types of aerators.

The QXB centrifugal submersible aerator is used for aerating and stirring the sewage mixture in the aeration tank and aeration sedimentation tank of sewage treatment plants, and for aeration in sewage biochemical treatment or aquaculture ponds.

Features:

1. The impeller is directly connected to the motor, with a simple structure, high efficiency, and long service life.

2. A mesh inlet can be added to prevent foreign objects from entering the body and causing damage.

3. The intake volume can be adjusted through the intake valve.

4. Except for the motor, all other components are made of stainless steel, carbon steel, and cast iron for selection.

In general centrifugal pumps, the power of submersible centrifugal aerators always increases with the increase of flow rate, which means that the power curve is a curve that decreases with the increase of flow rate. This is a problem that the use of pumps can bring: when the pump operates at the designed load. Generally speaking, the power of the pump is less than the rated power of the motor, and the pump is safe; But when the pump head decreases, the flow rate will increase, and from the performance curve of the pump, it can be seen that the power also increases.

When the flow rate exceeds the design point flow rate and reaches a certain value, the input power of the pump may exceed the rated power of the motor, leading to motor overload and burnout. Motor overload operation or protection system action stops the rotation of the pump; Or protect the system from burning the motor.
