How to choose a floating centrifugal aerator

Selection method of float centrifugal aerator

On the basis of the original QXB, the FQB3.0 float centrifugal aerator has changed from single-sided intake to double-sided or central intake, and a floating ring (made of stainless steel or fiberglass) is installed on the upper part of the intake pipe. The floating ring, intake pipe, and aerator are connected as a whole. As shown in the figure, the floating ring relies on the buoyancy of water to suspend the aerator in the water. The floating ring is pulled by three steel wire ropes, and the other end of the steel wire rope is fixed to the edge of the pool or fixed with three anchor points in the pond. During installation, place the aerator and floating ring into the water as a whole, and drag them to the designated area with steel wire ropes. Then fix the other end of the three steel wire ropes in three different directions at the edge of the pond. For ponds with larger water surfaces, three anchor points can be set up for positioning. During maintenance, simply untie the steel wire rope fixed at the edge of the pool, pull the equipment back to the edge of the pool and lift it out of the water.

product overview

FQB3.0 float centrifugeaeratorIt is the originalQXB submersible aeratorThe installation method of positioning the submersible motor at the bottom of the pool by its own weight has been changed to the installation method of using dual inlet pipes and suspending it in the water by a floating ring. presentDuring installation and maintenance of the QXB aerator, if there is water in the sewage tank and personnel cannot operate it, a crane needs to be inserted into the tank for lifting or transporting after draining the water. This installation form must be supported by a hard foundation or platform. The improved design of the QFB aerator not only works in the aeration tank, but also

4、 Technical features

1. Characteristics

a) The structure is compact, with a small footprint and easy installation.

b) Except for the intake port, the rest of the parts are submerged in water with low noise.

c) Inhale a lot of air, produce numerous and fine bubbles, and have a high dissolved oxygen rate.

d) No need to provide a gas source, eliminating the need for a blower and reducing project investment.

e) The impeller adopts a non blocking type, ensuring safe and reliable operation.

2. Construction and Engineering Process

The submersible aerator consists of a submersible sewage pump, a mixing chamber, a base, an intake pipe, and a muffler.

The upper end of the intake pipe is the air intake port, located above the water surface, and the lower end is connected to the mixing chamber. After the power is turned on, due to the rotation of the impeller, high-speed water flows out from the impeller outlet, forming negative pressure through the mixing chamber. Therefore, air is sucked in and mixed with sewage, and the mixed liquid flows out from the outlet, completing the oxygenation of the sewage.

5、 Transportation and usage precautions

1. It is absolutely not allowed to use the cable of the aerator to lift or suspend the aerator. When transporting or hanging the aerator, a chain hook with a fishing hook can be used on the handle or the upper cover lifting ring.

2. The fruit aerator is still in use or immersed in water, and can continue to be used at temperatures below 0 ° C.

3. The aerator uses grease or lubricating oil, which may leak out due to seal wear. At this moment. Please send the aerator to our company's maintenance department or authorized repair point as soon as possible to replace the seal, in order to avoid burning out the motor.

4. When the power is cut off, the aerator must not be moved and people must not enter the water.

5. After installation, the submersible aerator cannot be immersed in water for a long time. It is recommended to run it for at least 4 hours every half month to check its function and adaptability, or to lift it up and store it in a dry place for backup.

6. The submersible aerator cannot be placed outside the sewage inlet. When the chassis is placed on mud or floating sand, the submersible aerator sinks due to vibration. In this case, it is recommended to suspend the aerator or place it on a larger base plate.

7. The submersible aerator must ensure safety.
