Screw compressor air ends
Popular categories
The screw compressor air end is the main working unit of the compressor equipment, providing air compression. The increase in pressure of the incoming air flow occurs in the sealed housing of the unit, where two screw rotors (augers) are located: the leading one, connected to the electric motor shaft, and the driven one, driven by the clutch with the turns of the leading one. Air compression in screw-type compressors is performed in the inter-turn space. The air end has a long service life, but over time it requires repair or replacement. You can purchase a similar unit for AirHorse compressors in the Stancomplect online store.
Advantages of a screw compressor air end over other types of units
The main advantages that distinguish a screw compressor air end from other types of analogues include:
- Continuity of compressed air flow, no pulsations;
- High productivity (up to 60 m3 per minute and higher) with compact dimensions;
- Low noise and vibration levels;
- Ease of maintenance and durability - only an expensive centrifugal unit has a longer service life;
- High outlet pressure, comparable only to a piston block.
All the advantages of the screw compressor air end are clearly presented in the comparison table:
| Parameters | Compressor air-end type | ||||
|---|---|---|---|---|---|
| Screw | Piston | Spiral | Rotary plate | Centrifugal | |
| Continuity of flow | Continuous | Throbbing | Continuous | Almost continuous | Continuous |
| Productivity in m3 /min | 0.2-60.0+ | 0.1-5.0 | 0.05-1.0 | 0.1-5.0 | 10.0-500.0 |
| Pressure, bar | 5-15 (up to 30)* |
7-30 | 6-10 | 6-10 | 3-10 |
| Noise and vibrations | Low | Tall | Very low | Low | Average |
| Dimensions | Compact | More bulky | Very compact | Average | Very large |
| Energy efficiency | High | Average | High | Average | Very high |
| Service | After 2000-4000 hours** | Frequent*** | Minimal | Moderate | Only by specialists |
| Service life, thousand hours | 40-60 | 10-20 | 10-15 | 15-25 | 100+ |
| Price | Medium and high | Low | Average | Average | Very high |
* - with multi-stage compression;
** - oil and filter change;
*** - replacement of rings and valves
How to choose a screw compressor air end
To buy a screw compressor air end that suits your equipment, you need to consider the following when choosing:
- Unit performance;
- Outlet pressure;
- Overall dimensions;
- Type: oil-free or oil-filled;
- Operating mode: variable load or continuous.
When choosing a compressor air end for replacement, it is worth buying a unit of the same brand and model as the one installed by the manufacturer.
When replacement or repair of the screw compressor air end is required
Repair or replacement of the screw compressor air end is necessary if the following symptoms occur:
- Reduction in productivity and outlet pressure;
- Increased heating;
- Extraneous noise and increased vibration levels;
- Jamming or seizing of rotors;
- Oil leak.
