Air compressors and their main types

The modern market offers a huge selection of compressor equipment. It is designed to produce compressed air, which can be used to operate a pneumatic tool and other purposes. Devices differ in the principle of operation, dimensions, technical characteristics and other parameters. Before you buy an air compressor, you need to determine its appearance. The whole variety of devices can be divided into screw and piston.

Features of screw compressors

Devices of this type consist of a frame and 2 rotors: master and slave. They are connected to each other. The first through a belt or gear transmission is connected to an electric motor. The rotors rotate in different directions; as a result, a rarefied medium is formed in the chamber. This leads to the fact that the device sucks in air, it is sent to the receiver through the discharge channel.

During the operation of compressor equipment, oil is continuously directed to its working unit, it makes the functioning of the equipment more efficient and increases its durability. To get compressed air without oil impurities, the equipment is equipped with a filter system.

Features of reciprocating compressors

A piston compressor is simpler in design and affordable in comparison with screw counterparts. It can have a direct or belt drive. Compressors of the first type are classified into oil-free and oil. A key element of the equipment is the cylinder in which the piston moves. It makes reciprocating movements, due to them compressed air is created. The piston receives energy from the connecting rod, which in turn is connected to the crankshaft. It rotates due to the energy received from the engine and transmitted by direct or belt transmission..

When the piston drops, the cylinder fills with air, it enters through the intake valve. In a subsequent stroke, the air is compressed, sent to the exhaust valve, and from there it enters the receiver.

What to look for when choosing a compressor

There are parameters that should first be taken into account when choosing compressor equipment.

Air pressure. This is one of the most important parameters. It directly depends on the power of the device. The higher the air pressure, the better. You can find out about this parameter from the compressor documents.

Continuous operation. Some models are able to work without interruption for many hours, others require rest.

Power. To determine the required value, it is required to add up the need for air by all possible consumers and add 20%. The last point is that the compressor should not be operated at maximum load..

As you can see, there are a huge number of compressors. Each device has its own strengths and weaknesses. Having become acquainted with their types, as well as having examined the key selection parameters, you can choose the best equipment for your goals.
