Technology for assessing the technical state of a hermetic chilled compressor
The above technique of instrumental control of the technical state of a hermetically sealed refrigerant compressor makes it possible to perform qualitative and quantitative analysis of sound radiation from the constructive state of the device without analyzing it. Acoustic research of a domestic compressor is usually evaluated using mathematical-mechanical models, and many decisions are made on the basis of modeling. However, such an investigation is usually performed in a deterministic structure that can not consider the epistemic uncertainties arising, for example, by the processes of colliding elements of the gas distribution mechanism. The known methods for studying the sound emission of a gas-distributing mechanism, as a source of noise, do not take into account the interaction factor of the conjugate noise sources. The article compares the method of instrumental control, which makes it possible to determine the acoustic parameters on an open casing and the method of non-destructive testing of a compressor. The obtained results demonstrate reproduced and the accuracy of the study.
