Nanjing Jiangsu Sino German environmental protection production of submersible centrifugal aeration machine price is cheap, quality service! Jiangsu Nanjing German environmental protection equipment manufacturing Co Ltd in accordance with excellent technology, advanced management mode to the pioneering and innovative spirit, and work closely with renowned technical experts, create first-class diving aerator equipment products and services in the community. Under the support of the company's staff and users of all walks of life, submersible centrifugal aeration machine products will be better.
A centrifugal submersible aerator aeration tank for sewage treatment plant, aerated grit chamber, mixture of sewage sludge for oxygenating and mixing, and biochemical treatment or aquaculture oxygen of sewage.
The air flow was 10-32m3/h, aeration capacity 0.37-24kg2/h, motor power is 0.75-22kW.
Two, special point:
1) the structure is compact, the area is small, and the installation is convenient;
2) centrifugal submersible aerator except the inlet, the rest into the water to run, small noise;
3) submersible centrifugal aeration machine, the air is much more than the air bubbles, and the gas is fine, and the rate of dissolved gas is high;
4) submersible centrifugal aeration machine without the need to provide air source, eliminating the need for air blower, engineering investment;
5) submersible centrifugal aeration machine using the introduction of the German ABS submersible sewage pump technology, the impeller flow channel with no blocking, safe and reliable operation.
Three, principle
QXB type centrifugal submersible aerator adopts direct drive motor and impeller, centrifugal force generated by the rotation of the impeller is arranged around the water suction flow to form a low pressure area at the same time, the manufacturing of vacuum in the impeller inlet air inhaled, air and water in the mixing chamber is fully mixed to form gas water mixture evenly, discharged quickly in the centrifugal force under the action of.
Because the water jet is very strong, the effective flow of water cycle, so that the air is cut into a large number of tiny bubbles. Greatly increased the surface area, and because of the slow rise of air bubbles in the air in a large amount of oxygen dissolved in water, making the power efficiency is superior to other types of aeration machine.
Four, characteristics
1, the unique design of the gas mixing chamber, the amount of air intake, mixing effect is good, high oxygen utilization rate;
2, the mixture of air and water can be discharged from the air mixing chamber at a special angle, which can make the water flow into the horizontal direction and then upward flow;
3, the body sink into the water to run, no noise. The water inlet pipe can be installed muffler, enhance the silencing effect.

1, the scope of application
A new TQX type submersible aerator (hereinafter referred to as the aerator) suitable for aeration tank, the sewage treatment plant aeration sand pool, can also be used for small-scale sewage treatment works, industrial wastewater treatment and water reuse project, river landscape engineering.
2, working conditions
A, the medium temperature is not more than 40;
B, the pH value of the medium is between 5 and 9;
C, medium density does not exceed 1150kg/m3;
D, diving depth should not exceed the maximum allowable maximum dive depth;
The aeration machine should be completely under water, and can not work in the environment of inflammable and explosive environment or strong corrosive liquid!
3, structure and function:
3, 1 aeration machine:
The aerator consists of a submersible motor, an intake chamber, a mixing chamber, an impeller, a guide wheel, a base, an air inlet pipe and muffler. The intake pipe is connected with the upper end of the silencer, air inlet above the surface of water, and the lower end of the intake chamber are communicated. When running due to the rotation of the impeller, high speed flow from the impeller outlet through a mixing chamber to form negative pressure, the air through the air inlet chamber is sucked into the mixing chamber and the mixed sewage, gas water mixture from the mixing chamber flow jet, the completion of the sewage aeration. The specially designed aeration machine can achieve the best performance.
3, 1, 1 motor, motor aerator is a three-phase squirrel cage motor, IP68 protection, insulation grade of conventional F; motor can run continuously, also starts per hour within 10 times; the motor load at rated power when its rated voltage deviation is 380V + 5%; the temperature rise of the motor by peripheral circulation cooling water. The motor shaft and the rotor are composed of a rotor assembly, which is provided as an integral part.
3, 1, 2, the oil chamber by the bearing seat and the sealing seat of the formation of the cavity, the inside of the 32 mechanical lubricating oil for lubrication and cooling machine sealing, and with the role of isolated leakage fluid.
3, 1, 3, bearings are used imported one-time lubrication bearings, design life of 100000 hours or more.
3, 1, 4, sealing the aeration machine end face, radial seal with O type circle and plane sealantFor sealing; cable entrance is sealed by the special processing of the watertight cable into the motor to prevent external liquid; using two-way axial seal mechanical seal, respectively for the motor and the oil chamber is sealed; anticorrosive paint and polyurethane paint brush appearance and more effectively prevent the penetration of the surrounding liquid motor, oil chamber.
3, 1, 5, 2.2kW and above the rated power monitoring device of the aerator, respectively through the over temperature sensor has been set up (the stator is provided with a thermal switch two in series, with the temperature rise to 135 DEG C when the switch is off, cut off the power supply) and the oil chamber leakage protector (oil chamber is provided with a leak the probe, timely reflect the change of the resistance value of the oil chamber of oil-water mixture) on motor over temperature protection and monitoring the leakage of the oil chamber.
3, 1, 6, impeller optimization design to ensure efficient, non blocking operation.
1, 3, 7, mixed room air enters the mixing chamber to enter the mixing chamber for gas and water mixing, mixing evenly, high efficiency, and can control the jet direction.
