Vibration Signatures for Three Positive Displacement Compressors
David A. Yashar, William V. Payne
This report presents vibration data for three positive displacement compressors which will be used to evaluate Microelectromechanical Systems (MEMS) vibration sensors at a later time. The axial, radial and tangential vibration signatures of three compressors were measured under different operating conditions. An open-drive four cylinder compressor's vibration signatures were measured at discharge pressures of 1724 kPa (250 psig) and 2413 kPa (350 psig), with three different drive frequencies. A hermetic scroll compressor's vibration signatures were measured at three drive frequencies with a discharge pressure of 1724 kPa (250 psig), and at one drive frequency with a discharge pressure of 2241 kPa (325 psig). Finally a large, six-cylinder, chiller compressor's vibration signatures were measured with two, four, and six of the cylinders engaged.
