Scroll compressor structure diagram_Scroll compressor advantages and disadvantages

Scroll compressor structure diagram <img src="{{media url=&quot;Scroll_compressor_structure_diagram_Scroll_compressor_advantages_and_disadvantages.jpg&quot;}}" alt="" /> 　　 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. <img src="{{media url=&quot;Scroll_compressor_structure_diagram_Scroll_compressor_advantages_and_disadvantages2.jpg&quot;}}" alt="" />
