4,Noise levels (dB) and cooling method (air/water-cooled).
Working Principle
A rotary screw compressor using twin meshing screws for positive displacement air compression.Provides smooth, pulsation-free airflow with lower vibration/noise compared to piston blowers.The working cycle of screw blower can be divided
into three processes: suction, compression and exhaust. The cycle process is as follows:
1. Suction process
Picture ① : The air enters the volume between the teeth of the rotor through the suction port. As the rotor rotates, the volume between the teeth continuously expands.
Picture ② : When the volume between the teeth reaches the maximum, the volume between the teeth is disconnected from the suction port and the suction process ends.
2. Compression process
Picture ③: during compressing
3. Exhaust process
Picture ④: After the inter-tooth volume is connected to the exhaust port, the exhaust process begins. During the rotation of the rotor, the volume between the teeth continuously decreases, sending the compressed air to the exhaust pipe. This process continues until the volume reaches designed data.
Applications
Wastewater Treatment: Variable aeration demands in biological processes.
Industrial Processes: Pneumatic conveying, fermentation, or manufacturing requiring stable airflow.
HVAC Systems: Efficient air handling in large facilities.
