Résumé
Oil-injected twin-screw compressors are widely employed in many commercial and industrial applications because of their high efficiency and reliability. Although extensive literature on modeling techniques applied to twin-screw machines exists, researchers are continuously developing models to capture advanced physical phenomena occurring during the compression process (e.g., mass and heat transfer mechanisms) as well as analyze the mechanical behavior of the compressor (e.g., rotordynamics, bearing loads, variation of clearance gaps). To validate these models, detailed experimental data is needed to capture the in-chamber compression process as well as mechanical loads.
This paper presents the results of extensive experimental testing of a 4/6 oil-injected twin-screw compressor with slide-valve part-load modulation and economization. The compressor has been equipped with high-frequency pressure sensors, load-cells at the bearings and torque sensor on the main rotor. Indicated diagrams are analyzed to experimentally quantify the various losses, and the impact of compressor operating conditions on performance is discussed at full-load and part-load.
