Compressor Test Cell

Jason Kolodziej
Associate Professor

The RIT Compressor Test Cell houses an industrial-sized reciprocating compressor and accompanying professional data acquisition system. The unit is an 8,000-lb Dresser-Rand ESH-1, single stage, dual acting compressor with a 6” piston diameter and 5” stroke with air as the working fluid. While the operating flow and pressure is low (50 SCFM @ 50psi), the operating life expectance of this unit in service is decades with round-the-clock use and minimal maintenance using a variety of impure gases. Moreover, the unit is specifically designed to meet API standards required for use in the petrochemical industry. The compressor is presently instrumented with numerous pressure, temperature, flow, and vibration instruments that measure the operating characteristics of the unit. A rack-mounted data acquisition system, National Instruments-based (cDAQ & cRIO), is used to capture desired measurements. The primary goal of this lab is to support machine health monitoring research. Past projects have considered suction & discharge valve failure, main crank bearing failure, prognostic algorithms to predict remaining useful life of critical wear components, and novel sensor development such as wireless sensor transmission from hard-to-measure locations. In addition to research activities, several Multidisciplinary Senior Design teams have utilized this lab for their capstone design experience. Annual Dresser-Rand funded projects have included instrumentation installation & data acquisition, vibration suppression, a novel cooling system, and a wireless vibration sensor package.
