Most screw compressors available on the market are oil-flooded type twin rotors or single rotor designs. Vibration in these screw compressors can be subject to many variables such as operating conditions, applications, Vi (Built-in volume ratio), type of oil, type of oil cooling, machine layout, and other variables.
Correctly interpreting vibration data of screw compressors requires knowledge of the compressor’s mechanical design, operation, process of compression, and compressor controls. These can be real challenges in performing vibration analysis on industrial screw compressors.
