Lubrication Characteristics of Nano-oil at the Journal Bearing of Scroll Compressors

摘要：

The lubrication performance of refrigerant oil at the thrust-bearing and journal bearing of scroll compressors is one of the most significant factors.This paper presents the friction and anti-wear characteristics of nano-oil,a mixture of refrigerant oil and carbon nano-particles,at the journal bearing of scroll compressors.The tribological characteristics of nano-oil were evaluated by the disk-on-disk tester and the journal bearing tester for measuring the friction coefficient and the frictional surface temperature.In the journal bearing test,the average friction coefficient of high concentration nano-oil was decreased down to 18% compared to the average friction coefficient of raw oil under the normal load of 4,500 N and the rotating speed of 3600 rpm.It is believed that nano-particles can be coated on the wear surfaces and the interaction of nano-particles between surfaces can improve the lubrication in the frictional surface.Worn specimens were measured by straightness.Carbon nano-oil enhances the characteristics of the anti-wear and friction at the journal bearing of scroll compressors.
