The Effect of Refrigerant Dissolved in Oil on Journal Bearings Reliability
نویسندگان
چکیده
This paper presents how the refrigerant dissolved in oil affects on Journal bearings reliability. The bearing model test is performed using the hermetic test apparatus. The oil film pressure is measured under several types of bearing grooves, L/D ratios and mixing ratios of refrigerant to oil. As a result, the means by which the refrigerant dissolved in oil causes damage to journal bearings is made clear. That is, the fundamental problem is that the refrigerant gas, which evaporates and accumulates in the bearing clearance, disturbs the oil supply into the bearing. Also, it is found that the bearing groove, which is open to the bearing side, is effective to solve this problem.

متن کاملAssuring Reliability of Compressors Using HFC Refrigerants
In Japan, the refrigerant used in room air-conditioners has been changed from HCFC-22 (R-22) to R-410A, a blend of HFC-32 and HFC-125 (50/50 vt%), in order to protect the ozone layer. Generally, the miscibility between the refrigerant and refrigeration oil must be assured, because the oil needs to return to the compressor from the refrigeration cycle and lubricate the sliding parts. Alternative...

In this study, a practical numerical analysis has been developed in order to investigate the lubrication characteristics between a rolling piston and a crank of rotary compressors. This analysis is treated as a coupled problem of the momentum equations and the Reynolds equation of oil film. Using this analysis, the lubrication characteristics between the rolling piston and the crank for 2-cylin...

متن کاملReliability Evaluation of Rotary Compressor by Two-Parameter Step Stress Life Testing
One of major failure causes of rotary compressor is lubrication-related. Under the premise that bearings involve no major faults either in the design and material selection, their reliability is sensitive to the amount of system refrigerant charge and the amount of oil. These two factors, oil and refrigerant in the oil sump of rotary compressor are of great interest for lubrication failure mode...
