Submerged centrifugal aeration machine for industrial wastewater treatment submerged aeration machine
Submersible centrifugal aeration machine.
First, product overview:
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, end face and radial seal seal aeration machine with O type plane sealing ring and 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 appearance many times the coating can 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.

Characteristics of QXB centrifugal submerged aeration machine:
The higher oxygen dissolution rate, the ratio of tiny bubbles, the high filling efficiency and the wide oxygen filling area;
There is no dead zone in the pool, and the air entrainment of air bubbles can completely wash every corner of the bottom of the pool;
Has the advantages of simple structure, compact unit, long service life, the bearing can withstand heavy load, the shaft seal and oil bath air suction impeller cavity to prevent water when in contact with the seal, which ensure aeration machine in 24 hours of continuous work, long trouble free operation;
Saving engineering investment, no need to provide air source, eliminating the need for the blower, convenient installation, low noise;
