Scroll compressor structure diagram
Scroll compressor is a positive displacement compression compressor, the compression component is composed of moving scroll and static scroll. Its working principle is to use the relative orbital motion of the movable and static scrolls to form a continuous change in the enclosed volume, so as to achieve the purpose of compressing gas. Mainly used in air conditioning, refrigeration, general gas compression, and used in automobile engine supercharger and vacuum pump, etc., it can replace traditional medium and small reciprocating compressors in a large range.

The basic structure of is as follows:
Advantages and disadvantages of scroll compressor
Advantages:
1. There is no reciprocating mechanism, so the structure is simple, small size, light weight, few parts (especially few wearing parts), and high reliability;
2. The torque change is small, the balance is high, the vibration is small, the operation is stable, so the operation is simple and easy to realize automation;
3. It has high efficiency within the range of refrigeration capacity it adapts to;
4. Low noise.
Disadvantages:
1. The surface of the moving parts is mostly in the shape of a curved surface. The processing and inspection of these curved surfaces are more complicated, and some require special equipment, so the manufacturing cost is higher.
2. Between moving parts or between moving parts and fixed parts, a certain movement gap is often used to achieve the seal, and the gas will inevitably cause leakage through the gap, which limits the difficulty of the rotary compressor to achieve greater compression. Than, therefore, most rotary compressors are more used in air conditioning conditions.
3. High sealing requirements and complicated sealing structure.
