How does a roots blower work

• Working principle:
• Roots blower works with two rotors meshing with each other. When the gear drives the rotor to rotate, relative motion occurs between the two rotors, thereby forming airflow. One of the rotors is called the main rotor and the other is the passive rotor. The gear of the main rotor drives the passive rotor, which rotates simultaneously but in opposite directions. Gas is continuously entered and discharged in the gap between the two rotors, thereby generating pressure or extracting exhaust gas.
• Structural features:
• The rotor and casing of Roots blowers are usually made of high-strength alloy materials to ensure their durability and stability. The rotor surface is covered with coating to reduce internal friction and wear. In addition, the Roots blower is equipped with a cooling system to ensure the heat dissipation effect of the equipment during long-term operation.

Roots blower uses

• Roots blowers have a very wide range of applications and are mainly used in the following fields:
• ‌Aquaculture‌: Used to increase oxygen in fish ponds, increase breeding density, and increase production.
• ‌Sewage treatment‌: Used in the sewage treatment process for aeration, oxygenation, and backwashing to provide dissolved oxygen for aerobic bacteria in the water body and provide power for stirring the water body.
• ‌Cement Conveying‌: Used to transport cement and other powdery materials in cement production.
• ‌Power industry‌: used for combustion, pressurization, desulfurization, etc.
• ‌Other industrial applications‌: Including pneumatic transportation (such as transportation of small particles and powdery materials such as grain, cement, fly ash, etc.), mixing, composting, fermentation, drying air, vacuum suction, etc.

Roots blower pressure range

• The normal working pressure range of Roots blower is between 9.8kpa and 98kpa.
• This range can meet the needs of most industrial applications.
• However, for some special large-scale equipment or high-demand occasions, the pressure of Roots blower can even reach more than 140kpa.
• In addition, Roots blowers can also be divided into three types: low pressure, medium pressure and high pressure according to different pressures.
• Generally, those with a pressure between 9.8kpa and 58.8kpa are called low-pressure Roots blowers, while those with a pressure between 58.8kpa and 98kpa are called high-pressure Roots blowers. When the pressure exceeds 98kpa, it belongs to the high-pressure series.
