What is a roots blower used for?

• 1.Used for ventilation: Roots blowers can quickly transport gas from one area to another. Indoor ventilation is relatively common, so that good air quality and a comfortable working environment can be maintained.
• 2.Used for waste gas emission: In some industrial processes, a large amount of waste gas will be produced, which needs to be discharged, otherwise it will cause environmental pollution. The Roots blower can quickly discharge these waste gases to ensure the safety of the production process.
• 3.Used for pressurized transportation: In some industrial fields, such as water treatment, paper manufacturing, power generation, etc., compressed air needs to be transported to drive equipment and production processes. Roots blowers can compress gas and transport it to the required area.
• 4.Use in other fields: Roots blowers can also be used in sewage treatment, dust collection, paint spraying, food processing, equipment and other fields, and their value is relatively wide.

Root blower working principle

• The working principle of the Roots blower is to separate the air inlet and exhaust port through the "meshing" of a pair of rotors.
• The rotors are driven by a pair of synchronous gears to rotate at a constant speed in opposite directions, and the inhaled gas is discharged from the air without internal compression.
• The suction port moves to the exhaust port, and the moment the gas reaches the exhaust port, it is pressurized and transported due to the return flow of high-pressure gas on the exhaust side.
• Roots blower is a positive displacement blower. Its working principle is based on the relative movement of two blade-shaped rotors in the cylinder to compress and transport gas.
• This type of blower has a simple structure and is easy to manufacture.
• It is widely used in aquaculture oxygenation, sewage treatment aeration, cement transportation and other occasions.
• It is especially suitable for gas transportation and pressurization systems in low-pressure situations, and can also be used as a vacuum pump.
• There is a certain gap between the rotors of the Roots blower and they do not contact each other.
• This design allows the impeller to rotate without friction and does not require lubrication. Its operating temperature is usually not greater than 40°C.

Roots blower pressure range

• According to different usage requirements, the pressure of the Roots blower can be adjusted between 9.8kpa and 200kpa.Within this pressure range, the Roots blower can work normally and meet various process requirements.Specifically, the pressure range of Roots blowers includes:
• ‌Low pressure range‌: The pressure is lower than 58.8kpa, including 9.8kpa to 58.8kpa.This type of fan usually uses air cooling, and is mostly designed with a single oil tank.
• ‌Medium pressure range‌: The pressure is between 58.8kpa and 98kpa.This type of fan requires water cooling, and most of them are designed with double oil tanks.
• ‌High pressure range‌: When the pressure exceeds 98kpa, especially when it exceeds 140kpa, double-stage pressure boosting technology is required to ensure stable operation of the fan under high pressure.
