Screw air compressors have become the new mainstream in the development of today's air compressors. Compared with piston compressors with the same power, they have unparalleled advantages and superior performance and reliability. The vibration is small, the noise is low, the efficiency is high, and there are no wearing parts. The precise fit between the main and auxiliary rotors and between the rotor and the body shell reduces the backflow and leakage of gas and improves the efficiency; only the rotors mesh with each other and the cylinders do not reciprocate. , Reduced vibration sources and noise sources; unique lubrication methods bring many advantages:

1. With its own pressure difference, it constantly injects lubricating oil into compression chambers and bearings, simplifying the complex mechanical structure.

The injected oil forms an oil film between the rotors, and the main rotor can directly drive the secondary rotor to rotate without the need for a high-precision synchronous gear.

2. The injected lubricating oil can increase the tightness of the compression.

3. Lubricating oil absorbs a large amount of heat of compression. Therefore, even if the single-stage compression ratio is as high as 16, the head can still be controlled below the carbon content and deterioration temperature of general lubricants, and the expansion coefficient will not be different between the rotor and the housing. And it creates friction.

4. Lubricants can reduce the noise generated by high-frequency compression.
