Air Compressors Types and Accessories

It is a device that converts the force into kinetic energy by an air compression method and is known as an air compressor. Power is usually derived from diesel engines, electric motors or gasoline engines. Air compressors are widely used in various industries for safe, clean and convenient air use. The type of air compressor can be classified by positive displacement or negative displacement. They are as follows:

Reciprocating or piston compressors: Positive displacement compressors are the most common. Power varies from very small to extremely extreme. When the chamber is filled with air, the volume of the chamber is reduced and compressed to release energy. Internal components include valves, cylinders, crankshafts, pistons, and housing blocks.

Centrifugal Compressor: Accelerates air using a very high-speed impeller, not a volumetric compressor, and then uses a diffuser to shut off the air. This air compressor is used to increase the pressure by using dynamic compression method. Centrifugal compressors have many impeller / diffuser combinations and intercoolers that cool the air between stages.

Rotary screw compressor: This type is when the air compressor works by filling the air gap between the two spiral screws and the casing. Turning the screw decreases the volume and increases the air pressure. The compressor also places the oil in the bearing and compression zones. This mechanism works by cooling, lubricating, and creating a closure between the screw and the case wall, reducing internal leakage.

Rotary Sliding Vane Compressor: This positive displacement compressor consists of a stator, rotor and eight blades. Again, air is injected along the stator walls to cool the air and to supply lubricant to the vanes and bearings. A closure is created between the vane and the stator wall. As the rotor rotates, compression is created and the volume increases significantly.

Many accessories are required to operate the air compressor. In addition, it can be quickly restored when repairs are needed. Some of the most common accessories of air compressors are cooler, battery tray kit, compressor air filter, compressor separator kit, compressor oil, flywheel, compressor valve, engine driven compressor control, intake filter and silencer, system controller, oil guard, pneumatic tank Manifold, portable air tank conversion kit, positive exhaust blower accessories and so on.
