The origin of gas pulsations in rotary PD compressors: ΔP or ΔU?

Vibration Analysis of Rotary Compressors

By theoretically analyzing dynamic behavior of the crankshaft, the rolling piston and the blade inrolling-piston rotary compressors, constraint forces and sliding speed at each pair of movable machine elements were obtained, and unbalanced inertia forces and compressor vibrations were evaluated. It was concluded that theoretical results have a goodagreement with experimental ones. Moreover, it ...

Vibration-Acoustics Study of R410A Rotary Compressors

This paper demonstrates a typical process to investigate the vibro-acoustic behavior of R410A rotary compressors. The compressor shell is usually the main noise radiator in a rotary compressor. However, the accumulator shell can be a significant noise source as well, although its size is relatively small. Sound performance of a rotary compressor is affected not only by the dynamic characteristi...
