This chapter presents greater detail concerning the major components performance operational and installation considerations and standard specifications for reciprocating compressors. For normal production facilities reciprocating compressors far outnumber the other types and it is necessary for the facility engineer to understand the details of reciprocating compressor design. In very large horsepower ranges or booster compressor situations centrifugal compressors are common. These are not discussed in more detail in this book because these large installations are normally the responsibility of rotating machinery experts. COMPONENTS Figure 11-1 is a cutaway that shows the various components of a reciprocating compressor. To understand how to specify and maintain a compressor properly it is necessary to have a better understanding of the construction of the major components. Reviewed for die 1999 edition by Lonnie w.

The rated horsepower is determined by the maximum horsepower that can be transmitted through the crankshaft to the compressor cylinders. The rod load is the force imposed on the piston rod by the pressure differential between the two ends of the piston. Each frame is
