Liquid slugging
{{Orphan|date=April 2017}}
Liquid slugging is the phenomenon of liquid entering the cylinder of a reciprocating compressor, a common cause of failure.{{cite web|url=http://docs.lib.purdue.edu/cgi/viewcontent.cgi?article=2815&context=icec |date=2006 |title=The Detection of Liquid Slugging Phenomena in Reciprocating Compressors via Power Measurements |author1=Christopher R.

Under normal conditions, the intake and output of a compressor cylinder is entirely vapor or gas, when a liquid accumulates at the suction port liquid slugging can occur. As more of the practically incompressible liquid enters, strain is placed upon the system leading to a variety of failures.{{Cite web|url=http://www.rses.org/assets/rses_journal/0515_Compressors.pdf|title=Why Compressors Fail|website=RSES Journal|access-date=2017-03-31}}
