Leakage and wear characteristics of carbon seals for aero-engines
文献摘要：
Experimental investigation has been performed to study the leakage and wear character-istics of carbon seal working at high circumferential speed.To expand the scope of application,two newly designed carbon seals were compared:#1 Carbon Seal(CS1)with the inner diameter of 136 mm and including 4 segments,#2 Carbon Seal(CS2)with the inner diameter of 212 mm and including 6 segments.Air leakage tests were firstly conducted in the Medium-speed Seal Test Rig.The pressure ratio changed from 1.04 to 2.02 with the rotating speed varying from 0 to 18300 r/min.Of paramount concern was the durability test,including 300 h running time accumu-lated by three different working conditions,which was separately implemented on each carbon seal.The morphology variation of the friction surface,wear and leakage were recorded.Results indi-cated that the leakage monotonously increases with the pressure ratio and decreases with the rotat-ing speed.Comparing with CS1,more typical features exist on the friction surface of CS2,which are generated by more severe wear.Continually,leakage characteristics deteriorate.Furthermore,fitted formula has been educed for the life prediction of carbon seal,which could provide some supports for aero-engine design.
