. Two Rotors:Two symmetrical, figure-8 shaped rotors rotate without touching each other or the pump casing.
2. Gas Trapping:As they rotate, the rotors create expanding and contracting volumes between them and the casing, drawing in gas from the inlet port.
3. No Internal Compression:Unlike some other vacuum pumps, Roots pumps do not achieve compression internally.
4. Discharge to Backing Pump:The gas is then transported to the outlet, where a backing pump compresses it further and discharges it to the atmosphere.
5. Increased Pumping Speed:This combination effectively increases the overall pumping speed and reduces the final pressure of the vacuum system.
Key Characteristics
Positive Displacement:It's a positive displacement pump, meaning it moves a fixed volume of gas with each rotation.
High Pumping Speed:Roots pumps are known for their high volumetric displacement and high pumping speeds, allowing for faster pump-down times.
Requires a Backing Pump:A Roots pump cannot operate on its own and must be paired with a primary (backing) pump to handle the discharge of the compressed gas.
Dry Pumping:Many Roots pumps are dry, meaning they don't use oil for sealing or compression, which prevents contamination in clean vacuum processes.
Applications
Distillation and Thin Film Coating:Used in processes requiring high vacuum and fast pump-down, such as distillation and thin film deposition.
Metallurgy:Ideal for vacuum metallurgy, where a clean, oil-free environment is crucial for product quality.
Packaging and Food Processing:Utilized for high-volume gas removal and maintaining vacuum in these industries.
