The question that everyone has been confused about
Thread Content
Based on the role of the piston within the cylinder, they can be classified as single-acting compressors, in which the compression cycle occurs only at one end of the cylinder； (2) Double-acting compressor, with the same compression cycle taking place at both ends of the cylinder ； (3) Differential compressor, in which two or more compression cycles of different stages take place at one or both ends of the cylinder. Who can explain it in detail? How to understand the same level? How should I understand performing two or more compression cycles of different levels at one or both ends? It’s too complicated; I hope an expert like Haiyou can help.
Double-acting means that gas compression occurs on both sides of the piston, and the suction sides of the valves on both sides are connected to the same pipeline, as are the discharge sides; in other words, they belong to the same stage. In the differential type, the compressed gas on either side of the piston comes from or is discharged into different pipes, meaning compression occurs at different stages.

In my understanding, at the same stage there is only one pressure level; compression cycles of two or more different levels take place at one or both ends, and this phenomenon is seen only in cylinders with a differential pressure setup, meaning that the pressure of the compressed gas varies.
In my opinion, \"extremely poor\" means that the compressed gas in the cylinder belongs to two different pressure levels
To address this issue, it is first necessary to determine the locations of the inlet and outlet valves. Single-acting valves have them only on one side of the piston, while double-acting valves have them on both sides of the piston. In the case of multi-stage systems, there are two pistons of different diameters on a single piston rod, along with cylinders that match the size of those pistons. With such a valve configuration, different piping arrangements can be used, thereby enabling multiple stages to be achieved.
