Product Details

Before starting the centrifugal submersible aerator, a qualified electrician should inspect the system to ensure that the following electrical protection measures are taken.

1. Before operating the submersible aerator, a 0-500V megohmmeter should be used to check the insulation resistance of the motor stator winding, which should not be lower than 1 megohm.

2. The power supply voltage must be within the range of 5% of the rated voltage indicated on the nameplate. The increase in power supply voltage is not allowed to exceed 10% of the rated voltage. If the power supply is far away from the location where the centrifugal submersible aerator is used, the cross-sectional area of the cable should be increased and the joints should be minimized as much as possible, otherwise the voltage will drop too much. The joints should be sealed and waterproof.

3. In a four core cable, the one with a grounding symbol is the ground wire, usually a yellow green wire. To ensure this, the ground wire must be firmly connected and 50mm longer than other wires

4. Check the rotation direction of the impeller of the submersible centrifugal aerator.

The submersible aerator using three-phase power supply should be checked for rotation direction after initial start-up or each reinstallation. Incorrect rotation direction can reduce efficiency and damage the water pump.

Each centrifugal submersible aerator from Nanjing Lanjiang Equipment undergoes a thorough final inspection before leaving the factory. *The lubricated ball bearings provide durability to the submersible centrifugal aerator. However, in order to ensure the service life of the submersible centrifugal aerator, it is recommended to conduct regular inspections and maintenance.

QXB centrifugal aerator product introduction

Product information of centrifugal submersible aerator

Name: QXB type cast centrifugal submersible aerator

Brand: Nanjing Lanjiang

Model: QXB22

Material: Shell, intake pipe muffler, aeration disc made of carbon steel material

Product features of centrifugal submersible aerator

1. High oxygen dissolution rate, high proportion of small bubbles, high oxygenation efficiency, and wide oxygenation area;

There are no dead zones in the two pools, and the horizontal aeration flow carrying bubbles can flush every corner of the pool bottom;

3. Bearings with simple and compact structure, long service life of the unit, and the ability to withstand high loads, using oil bath shaft seals and air suction into the impeller chamber to prevent water from coming into contact with the seals during operation, all ensure that the aerator can work continuously for 24 hours and operate for a long time;

4. Save engineering investment, no need to provide gas source, eliminate blower, easy installation, low noise;

Application of QXB centrifugal aerator

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.

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. If the aerator is still in use or immersed in water, it 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.
