How does Roots blower aerate? How to choose?

Roots blower is a common aeration equipment, mainly used in water treatment, wastewater treatment, sewage treatment and other fields. It absorbs and compresses the gas through the rotating gear movement, so as to achieve the effect of aeration.

Here are some basic knowledge about aeration and selection of Roots blower:

　　1. Aeration principle: Roots blower absorbs the air at the air inlet into one of the chambers through the gear movement of the double rotors, and gradually compresses and finally discharges with the movement of the rotors. The air flow and pressure change generated by this movement can push the gas from the bottom up to realize the supply of dissolved oxygen in water.

　　2. Aeration effect: Roots blower has high aeration efficiency and stability, can provide uniform bubble distribution, and can produce large aeration volume. This is very important for applications such as wastewater treatment that require a large amount of oxygen supply.

3. Selection and installation: The following factors shall be considered when selecting Roots blower:

-Aeration demand: determine the required fan model and aeration volume according to the actual aeration demand.

-Pressure and flow: select the appropriate fan model and working point according to the requirements of system aeration and water pressure.

-Energy consumption and efficiency: compare the energy consumption and efficiency of different types of fans, and select economic and efficient equipment.

-Noise and vibration: Considering the noise and vibration level of Roots blower, select the equipment that meets the requirements.

-Maintenance and operation costs: Considering the maintenance and operation costs of equipment, select the appropriate Roots blower.

Pay attention to the following points during installation:

-Installation position: select a position that is stable and away from vibration and impact.

-Air inlet pipe: ensure that the air inlet pipe is free of leakage, and install a filter for dust and impurities to enter.

-Exhaust pipe: install proper exhaust pipe to avoid airflow blockage.

-Maintenance: regularly check the operation condition of the fan, the status of the lubricating oil and seals, and timely carry out maintenance.

The above is a basic introduction to the aeration and selection of Roots blower. I hope it can help you. If you have any other questions, please ask.
