This paper describes the experimental and analytical techniques used to identify and correct the noise and vibration concerns in a new family of reciprocating compressors. Operating sound, vibration and pressure pulsation data were acquired simultaneously on a prototype compressor. Analysis of this data led to two areas of concern. The first concern was identified using Operating Deflection Sha...

This paper proposes a low vibration stopping method by switching between the free-run and short-circuit braking modes of compressor. Vibrations are generated bouncing rotor caused load torque fluctuations. The proposed suppresses motor during suction process, thereby preventing generation large torque. In order to stop switches from mode at top dead center, which is starting point process. Furt...

The working process of oil-injected scroll compressor is analysed in this paper. The thermodynamic and dynamic models arc developed for the oil-injected scroll compressor. The property parameters can be calculated under the influences of the leakage and the friction. The results of computer simulation are coincident with the experiment's. so it is useful to predict the compressor performance. I...
