About rotary screw compressor work diagram should know

Since 1934, when Swedish engineer Alf Lysholm first proposed the screw compression rotor technology, the screw rotor air compressor has been continuously developing and improving. Today, the twin-screw technology is the mainstream of the market and is widely used in mineral mining and medical fields.

Due to its stable and efficient characteristics, the screw air compressor has become the first choice for most enterprise workshops and equipment upgrades. Understanding the working principle and function of a screw air compressor is crucial for operators and maintenance personnel. Even operators who are proficient in using pneumatic tools can have a deeper understanding of the screw air compressor.

Composition of rotary screw air compressor
It consists of a casing, a rotor, a bearing, a lubrication system and a control system. The gas is compressed by rotating two intermeshing screws to change the volume.


Working principle of rotary screw air compressor
1. Inhalation: The rotor rotates, the tooth space is connected to the air inlet, and air is sucked in through negative pressure
2. Delivery: The rotor tooth peaks and the casing form a sealed space, and the air is pushed to the compression area along the axial direction
3. Compression: The meshing surface gradually shrinks and is compressed to a high pressure state
4. Exhaust: The compressed gas is discharged through the exhaust port

Advantages of rotary screw air compressor
1. High efficiency and energy saving
Twin-screw continuous compression structure, less gas leakage, and frequency conversion technology can automatically adjust the power according to the gas consumption.

2. Low noise
Low vibration, further noise reduction through silencer design.

3. Adapt to special environments
Stable operation at -18~50℃, wide pressure range.

4. Long service life
Compact structure, few parts
