R290与R410A旋转式压缩机滑片-活塞摩擦副特性的对比
Comparison of Tribological Characteristics of Vane-piston Interface between R290 and R410A in Rotary Compressor
摘要
Abstract
R290 has been considered for use in air-conditioning systems as a low global wanning potential (GWP) refrigerant.This paper describes the tribological characteristic of the vane-piston tribopair in a R290 rotary compressor.For the purpose of simulating the tribopair working conditions,the vanes and rolling pistons of a compressor were directly adopted as test specimens.All of the tribological tests were performed under sealed high-pressure conditions,with test conditions such as the relative sliding speed,loads,and temperatures set based on actual operating conditions of a compressor,and the friction coefficients,scuffing resistances,and wear depths were measured.Furthermore,the morphological changes were investigated using a scanning electron microscope after the tests.As a comparison benchmark,tests were also conducted using R410A/polyolester oil.From these tests,it was evident that the friction coefficients and scuffing load of the vane-piston interface in the presence of R290/mineral oil were respectively 0.05-0.10 and 300 N higher than those of R410A/polyolester.On the other hand,the wear resistance ability with R290/mineral oil was better than that with R410A/polyolester.关键词
