This paper describes the experimental study of the shaft oil feed mechanism of a rotary compressor. The oil contained in the shaft in which an oil pump is inserted is fed to the respective sliding surfaces of the subbearing section, eccentric section and main bearing section of the shaft by centrifugal force of shaft rotation. The oil feed pressure of shaft rotation is approximately 0.1 kg/cm2 ...

Abstract To explore the sensitivity sorting of a one-dimensional performance prediction model, high-load centrifugal compressor is studied. Using Latin Hypercube method, influencing factors model are designed. Based on analysis ANOVA, main pressure ratio and efficiency investigated, guidance for optimization proposed. The results show that affecting deviation loss, radial diffuser incidence imp...
