A Dresser Roots blower is a type of positive displacement rotary lobe pump, also known as a Roots blower. It’s a specific brand of blower manufactured by Dresser, and is used in various industrial applications. These blowers move air or gas by trapping a fixed volume between rotating lobes and pushing it from the intake to the discharge side.
Here’s a more detailed explanation:
Positive Displacement:
Roots blowers are positive displacement machines, meaning they deliver a consistent volume of air or gas for each rotation, regardless of the discharge pressure.
Rotary Lobe Design:
They feature two impellers (lobes) that rotate in opposite directions within a casing, trapping air or gas and moving it from the intake to the discharge side.
Applications:
Roots blowers are used in various applications, including:
Material Handling:Pneumatic conveying of materials like fly ash.
Pollution Control:Part of flue gas desulfurization systems.
Industrial Processes:Supplying air for aeration in wastewater treatment, mixing in industrial processes, and more.
Automotive:Historically used as superchargers in vehicles.
