Description

Technical Field

[0001] The utility model belongs to the technical field of compressors and relates to a double-jointed dual-control compressor, in particular to an integral gear type double-jointed dual-control compressor. Background Art

[0002] Typically, a single chemical production process requires multiple compressor units with different inlet and outlet conditions or different media compositions. However, existing integral gear compressor units operate with the same media in each compression stage, and the inlet and outlet conditions between stages are interrelated. Consequently, the entire production process requires multiple compressor units, resulting in a large equipment footprint, numerous moving parts, high investment costs, and a complex and lengthy piping system. This results in significant unnecessary energy loss and over-design due to subcontracting of moving parts. The complex control system makes it difficult to scale up smart, unmanned factories and significantly increases ongoing maintenance costs.
