Compression principle

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

What are the key components of an air compressor system?

An air compressor system consists of several key components that work together to generate and deliver compressed air. Here are the essential components:

1. Compressor Pump: The compressor pump is the heart of the air compressor system. It draws in ambient air and compresses it to a higher pressure. The pump can be reciprocating (piston-driven) or rotary (screw, vane, or scroll-driven) based on the compressor type.

2. Electric Motor or Engine: The electric motor or engine is responsible for driving the compressor pump. It provides the power necessary to operate the pump and compress the air. The motor or engine’s size and power rating depend on the compressor’s capacity and intended application.

3. Air Intake: The air intake is the opening or inlet through which ambient air enters the compressor system. It is equipped with filters to remove dust, debris, and contaminants from the incoming air, ensuring clean air supply and protecting the compressor components.

4. Compression Chamber: The compression chamber is where the actual compression of air takes place. In reciprocating compressors, it consists of cylinders, pistons, valves, and connecting rods. In rotary compressors, it comprises intermeshing screws, vanes, or scrolls that compress the air as they rotate.

5. Receiver Tank: The receiver tank, also known as an air tank, is a storage vessel that holds the compressed air. It acts as a buffer, allowing for a steady supply of compressed air during peak demand periods and reducing pressure fluctuations. The tank also helps separate moisture from the compressed air, allowing it to condense and be drained out.

6. Pressure Relief Valve: The pressure relief valve is a safety device that protects the compressor system from over-pressurization. It automatically releases excess pressure if it exceeds a predetermined limit, preventing damage to the system and ensuring safe operation.

7. Pressure Switch: The pressure switch is an electrical component that controls the operation of the compressor motor. It monitors the pressure in the system and automatically starts or stops the motor based on pre-set pressure levels. This helps maintain the desired pressure range in the receiver tank.

8. Regulator: The regulator is a device used to control and adjust the output pressure of the compressed air. It allows users to set the desired pressure level for specific applications, ensuring a consistent and safe supply of compressed air.

9. Air Outlet and Distribution System: The air outlet is the point where the compressed air is delivered from the compressor system. It is connected to a distribution system comprising pipes, hoses, fittings, and valves that carry the compressed air to the desired application points or tools.

10. Filters, Dryers, and Lubricators: Depending on the application and air quality requirements, additional components such as filters, dryers, and lubricators may be included in the system. Filters remove contaminants, dryers remove moisture from the compressed air, and lubricators provide lubrication to pneumatic tools and equipment.

These are the key components of an air compressor system. Each component plays a crucial role in the generation, storage, and delivery of compressed air for various industrial, commercial, and personal applications.
