rotor progressive cavity pump parts
- An opening valve sucks gas into the compressor chamber. Located in the chamber are the two screw rotors; when the machine is on, they will rotate at high speeds.
- As the impellers rotate, they trap and isolate air in the cavities between the rotors, thus moving the air down the chamber.
- The chamber decreases in size and is moved away from the opening valve. As the volume decreases, the pressure increases.
- Pressurisation builds and thus the air is condensed.
- Air pressure will trigger the compressor’s discharge valve to open, allowing the pressurised air to enter a receiver or other holding tank.
- Air is compressed and can be transferred to downstream equipment such as dryers and oil/water separators for drying and contamination removal.
