Working principle

The compression process of the oil-free scroll is realized by the rotating motion of the stationary scroll and the movable scroll.
The air enters from the outside of the main engine, and after the air is sucked in, the moving scroll closes the air inlet. With the rotation of the movable scroll, the air is continuously compressed, and the compressed oil-free air is sent from the center of the stationary scroll. This process is repeated continuously to ensure that the discharged compressed air is continuous and without fluctuation.

What are the different types of air compressors?

There are several different types of air compressors, each with its own unique design and operating principle. Here’s an overview of the most commonly used types:

1. Reciprocating Air Compressors: Reciprocating air compressors, also known as piston compressors, use one or more pistons driven by a crankshaft to compress air. They operate by drawing air into a cylinder, compressing it with the piston’s up-and-down motion, and discharging the compressed air into a storage tank. Reciprocating compressors are known for their high pressure capabilities and are commonly used in industrial applications.

2. Rotary Screw Air Compressors: Rotary screw air compressors utilize two interlocking screws to compress air. As the male and female screws rotate, the air is trapped between them and gradually compressed as it moves along the screw threads. These compressors are known for their continuous duty cycle, high efficiency, and quiet operation. They are widely used in industrial, commercial, and automotive applications.

3. Centrifugal Air Compressors: Centrifugal air compressors rely on the principle of centrifugal force to compress air. They use a high-speed impeller to accelerate the incoming air and then convert the kinetic energy into pressure energy. Centrifugal compressors are commonly used in large-scale industrial applications that require high volumes of compressed air.

4. Rotary Vane Air Compressors: Rotary vane air compressors employ a rotor with sliding vanes that compress the air. As the rotor rotates, the vanes slide in and out of the rotor, creating compression chambers. Air is drawn in, trapped, and compressed as the vanes move. These compressors are compact, reliable, and suitable for small to medium-sized applications.

5. Axial Flow Air Compressors: Axial flow air compressors are primarily used in specialized applications such as aircraft engines and gas turbines. They utilize a series of rotating and stationary blades to compress air in a continuous flow. Axial flow compressors are known for their high flow rates and are designed for applications that require large volumes of compressed air.

6. Scroll Air Compressors: Scroll air compressors consist of two interlocking spirals or scrolls that compress the air. One spiral remains stationary while the other orbits around it, creating a series of expanding and contracting pockets that compress the air. Scroll compressors are compact, reliable, and commonly used in applications where low noise and oil-free air are required, such as medical and dental equipment.

These are just a few examples of the different types of air compressors available. Each type has its own advantages, capabilities, and ideal applications. The choice of air compressor depends on factors such as required pressure, flow rate, duty cycle, noise level, oil-free operation, and specific application requirements.
