What is a roots blower?

Roots blowers are oil-free, air-cooled technologies comprised of two rotors that spin in the opposite direction. A positive displacement lobe works by pumping a fluid with a pair of meshing lobes similar to a set of stretched gears.

Applications of roots blowers

Roots blowers supply pressurized and vacuum gases for various industrial applications. They have wide applications that include

Things to consider when choosing a roots blower for your application

1. Air volume: The air volume is the gas the roots blowers delivers per unit of time. In some applications like cement transportation and boiler return roots blowers are only auxiliary equipment, and it is not possible to know the required air volume parameters one can provide the delivery volume per unit time like conveying 15 tons of cement per hour. Thus, the air volume parameter is one aspect that must be considered when choosing a roots blower.

2. Pressure: It refers to the outlet pressure and the pressure the roots blower needs to overcome. Roots blower is a positive displacement blower, and the pressure depends on the front pipe and atmospheric pressure, known as back pressure. The pressure gauge shows the same pressure, and if the pressure exceeds the rated pressure, the roots blower will be in an overpressure condition, and the motor will burn.

3. Rotate speed: The rotation speed affects two aspects &#; air volume and service life of the blower. When all the parameters are the same except the rotation speed, the higher the speed, the larger the blower volume. Blowers with high speed will have a shorter service life. Consider rotating speed when choosing roots blowers for your application.

4. Transport medium: The roots blowers cannot transport all types of gas like high acidity gas and alkaline and flammable and explosive gases. The potent corrosive gases damage the roots blowers easily. Choose the roots blowers as per the air volume and pressure; there are specific needs for transport medium.

5. Sealing method: Another aspect one must consider is the sealing method. The sealing method of roots blowers is labyrinths. Unique sealing methods like pistons, rings, and mechanical seals are required when special gases are transported. The difference in the sealing method will cause price fluctuations, and it is also one of the necessary parameters for selection.
