Description of the Experimental Method and Procedure of Model Wear Test of Refrigeration Compressors’ Parts

Abstract:

Friction nodes in refrigeration compressors are lubricated with a mixture of lubricating oil and refrigerant. The concentration of refrigerant in oil depends on temperature and pressure of the refrigerant. Determining the effect of this mixture on the size of wear in refrigeration compressors in laboratory conditions is only possible through an accurate reflection of friction parameters.The authors managed to prepare a prototype stand for a tribological test with a model block-on-ring friction node and the high-pressure chamber allowing for simulated conditions in refrigeration compressors. The present paper includes the description of the experimental method and procedure of model wear test of refrigeration compressors parts. The study itself constitutes the basis for the verification tests of the stand.
