چکیده

The performance of air conditioner and the reliability of compressor could be reduced, if the refrigerant gas is discharged from compressor with excessive lubricating oil. Thus, the study of the reduction of the oil circulation rate in the compressor is required to resolve the problem. In this paper, five feasible approaches to decrease the oil circulation rate were confirmed by experiment. the experimental results shows that the effect of the vortical oil separator based on the centrifugal theory is best of all, installed in the compressor motor rotor ,with oil circulation ratio less than 0.1wt%.

An Experimental Study of the Shaft Oil Supply Mechanism of a Rotary Compressor

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 ...
