Understanding rod load - Knowing crosshead pin load and gas load helps operators accurately rate reciprocating compressors

摘要

Reciprocating compressors are usually rated in terms of horsepower, speed id rod load. While horsepower and speed are easily understood, the term "rod load" is interpreted differently by various users, analysts, OEMs, etc. "Rod load" is one of the most widely used, but least understood reciprocating compressor descriptors in industry. Typical end users know that rod load is a factor used to "rate" a compressor, but they don't generally have a good understanding of how this rating is developed and how to utilize it for machinery protection.
