Air compressor and compressor are not the same thing. What is the difference?

Students who have just come into contact with air compressors and compressors often have a wrong concept: air compressors are compressors. In fact, air compressors and compressors are actually two different mechanical products, although they have certain commonalities and connections.

1. Concepts and differences between the two

An air compressor is an air compressor. It is mainly used for mechanical products of compressed air, which can be used in many places. For example, one of the most commonly used functions of the air compressor is to compress air to be used as power, which is widely used in the power industry. In addition, it can also be used to cool and separate gas, transport gas and so on. It plays a very important role in life and work.

The compressor is a general term, which is a driven fluid machinery that promotes low-pressure gas to high-pressure gas. There are many types of compressors, such as refrigerant compressors, hydrogen compressors and air compressors. Air compressor is only one kind of compressor.

Many people think that an air pump is an air compressor. The air pump is the piston type air compressor mentioned a long time ago. Now there are many types of air compressors, such as screw machine, oil-free machine, energy-saving variable-frequency air compressor, etc. The principle of air pump and air compressor is different.

2. Principle of both

Working principle of air compressor: Taking screw air compressor as an example, the working cycle of screw compressor can be divided into three processes: intake (1), compression (2, 3) and exhaust (4). As the rotor rotates, each pair of meshing teeth successively complete the same working cycle.
