The 3-lobe version of the Roots blower was developed as a refinement of the original 2-lobe design. It aimed to address some of the limitations in terms of efficiency and performance, particularly in specific applications where greater flow stability, lower pulsation, and improved power efficiency were needed.
WORKING PRINCIPLE
| Step | Description |
|---|---|
| 1. Rotor Design | The blower consists of three intermeshing lobed rotors (typically in a figure-eight shape), which rotate inside a casing without touching each other. |
| 2. Air Intake | As the rotors rotate in opposite directions, they trap a fixed volume of air between the lobes and the casing, drawing air in through the intake port. |
| 3. Compression | The trapped air is moved toward the discharge side. As the rotors continue rotating, the volume between the lobes decreases, compressing the air. |
| 4. Air Discharge | Compressed air is expelled through the outlet port at a higher pressure. The constant flow rate is maintained despite pressure changes due to positive displacement. |
