Installation Method of FQXB3KW Centrifugal Float Aerator
1、 Product Overview
FQB submersible floating aerator is the original QXB submersible aerator（ electric machinery The installation form of positioning at the bottom of the pool by self weight is changed to the installation form of using double air inlets and floating rings to suspend in the water. During the installation and maintenance of NQXB type aerator, if there is water in the sewage pool, the personnel cannot go down to the pool for operation, and the crane needs to be inserted into the pool for hoisting or transport after the water in the pool is discharged. Moreover, this installation form must be supported by a hard foundation or platform. The FQB type aerator after improved design is not only suitable for working in the aeration pool, but also suitable for working in oxidation ponds, fish ponds, landscape lakes, sewage channels It works in soft foundation environment such as river channel, so the FQB designed after improvement makes installation more convenient, time-saving and labor saving, and expands the use range of diving aeration.
2、 Operating principle Installation Method of QFB3KW Centrifugal Float Aerator
On the basis of the original NQXB, FQB changes unilateral air intake to bilateral air intake or air intake, and the upper part of the air intake pipe is equipped with a floating ring (stainless steel or Glass Steel). The floating ring, air inlet pipe and aerator are connected as a whole. As shown in the figure, the floating ring makes the aerator suspended in the water by the buoyancy of water. The floating ring is pulled by three steel wire ropes, and the other end of the steel wire rope is fixed at the side of the pool, or three anchor points are set in the pool to fix it. During installation, put the aerator and floating ring into the water as a whole, drag them to the predetermined area with wire ropes, and then fix the other end of the three wire ropes at the side of the pool in three different directions. The pond with large water surface can be set with three anchor points for positioning. During maintenance, just untie the steel wire rope fixed at the pool side, pull the equipment back to the pool side and lift it out of the water.
The upper end of the intake pipe is the air intake, which is located above the water surface. The lower end is connected with the mixing chamber Power Supply Later, due to the rotation of the impeller, the high-speed water flows out from the impeller outlet and forms negative pressure through the mixing chamber, Therefore, air is sucked in and mixed with sewage, and the mixed liquid flows out from the outlet to complete the oxygenation of sewage.
3、 Structural characteristics
1. Floating positioning, easy installation, free layout and movement without interrupting process operation;
2. Compact design structure, no external air source is required to use the self-priming function, and the bubbles are uniform;
3. The main engine operates underwater without ground equipment and has low noise;
4. It can be directly used in oxidation ponds, rivers, fish ponds and other large areas of water without infrastructure;
5. It has mixing function during aeration.
4、 Technical characteristics
QFB submersible floating aerator is turned from buoy to concealed mode Bracket , submersible motor, mixing chamber, base, intake pipe and silencer. The main structure, performance parameters and overall dimensions of NQXB submersible centrifugal aerator are the same * * *. Model selection shall be determined according to NQXB series
V. Main technical parameters:
It is never allowed to use Cable Line movement. The chain can be hooked on the handle or the lifting ring of the upper cover.
Before initial startup, check the rotation direction of the impeller. If the rotation direction is incorrect, the efficiency will be reduced and the motor will be damaged. Do not move the aerator without disconnecting the power supply.
Precautions for transportation and use
1. Never lift or suspend the aerator with the cable of the aerator. When carrying or hanging the aerator, the chain with hook can be hooked on the handle or the upper cover ring.
2. If the aerator is still in use or immersed in water, it can continue to be used when the temperature is below 0 ° C.
3. The aerator uses grease or lubricating oil, which may leak out due to seal wear. At this time. Please send the aerator to our company's maintenance department or entrusted maintenance point as soon as possible to replace the seal to avoid burning the motor.
4. When the power supply is not cut off, the aerator shall not be moved, and people shall not enter the water.
5. After installation, the buoy submersible aerator cannot be immersed in water for a long time. It is recommended to run for at least 4 hours every half month to check its function and adaptability, or lift it and put it in a dry place for standby.
6. The buoy submersible aerator cannot be placed outside the sewage inlet. When the chassis is placed on mud or floating sand, the pontoon submersible aerator will sink due to vibration. In this case, it is recommended to suspend the aerator or place it on a larger bottom plate.
7. Float submersible aerator guarantee.
