The objective of this course is to provide an introductory eduation in reciprocating compressor performance measurement and mechanical condition analysis utilizing state-of-the-art analysis equipment. The course is designed for engineers and technicians who work with compressor reliability, optimization, and maintenance.

Course Summary
● A discussion of reciprocating compressor design
- Slider-crank mechanism
- Double-acting cylinder design
- Piston design (piston rigns, rider rings)
- Compressor valves
- Distance piece size, piston rod L/R
- Pulsation dampeners, process gas piping
● An introduction to reciprocating compressor theory
- Positive displacement compression
- Pressure-volume diagram
- How P-V diagram is tied to mechanical actions
- How P-V diagram is influenced by performance or mechanical changes
● Potential reciprocating compressor faults
- Ring leakage/failure
- Valve leakage/failure
- Packing leakage/failure
● Basic instrumentation required for performance measurement (encoders, transducers, signal processors, displays, data storage, etc.)
● Performance measurement (rpm, horsepower, capacity, losses)
