roots blower working principle

The Roots Blower is a Positive Displacement machine. This means it delivers a nearly constant volume of air or gas with each revolution, regardless of the discharge pressure (within its operating limits).

The working principle is straightforward:

• Intake Phase: As the two synchronized rotors rotate in opposite directions inside the housing, they create a vacuum at the inlet port. This action draws in a measured volume of air or gas.
• Trapping Phase: The air/gas is trapped in the pockets formed between the rotors and the inner walls of the casing.
• Transfer Phase: The rotors carry the trapped air/gas from the inlet side to the discharge side along the casing walls.
• Discharge/Compression Phase: When the pocket opens to the discharge port, the higher-pressure gas from the outlet flows back into the pocket. It instantaneously compresses the newly transferred gas. This process, known as external compression, raises the pressure before the air/gas is discharged into the outlet pipe.

The continuous rotation of the lobes ensures a steady, non-pulsating flow of air/gas for industrial use.

Assembly and Construction

The construction of a Roots Blower from JD Vacuum Service, which is a common industrial design, features a simple and rugged construction. It is designed for long-lasting, trouble-free operation.

Key components in the assembly include:

• Casing/Housing: A precisely machined body, often made of Cast Iron (C.I.), that encloses the rotors. It has an inlet port for drawing in air/gas and an outlet port for discharge.
• Rotors/Lobes: Two identically shaped, counter-rotating lobes (usually twin-lobe or figure-eight shaped) that spin within the casing. They are precision-machined to maintain a minimal, non-contacting clearance with each other and the casing.
• Timing Gears: A set of precision gears is located outside the pumping chamber. These gears synchronize the rotation of the two rotors, ensuring they rotate in opposite directions without touching. This non-contact operation allows for oil-free air delivery.
• Shafts and Bearings: The rotors are mounted on shafts supported by bearings. These are often cylindrical roller bearings to ensure smooth, low-friction rotation.
• Seals: Mechanical or piston ring seals are used to prevent leakage of the pumped gas from the working chamber. They also prevent the lubricant from the gears and bearings from entering the gas stream, ensuring oil-free operation.
• Drive: The blower is typically electric-driven, connected to a motor via a belt or coupling.
