Kub Kub Alloy Seal Ring
Lub High Temperature Alloy Seal Ring yog engineered rau turbine interstage sealing nyob rau hauv aircraft xyaw. Nws ua tiav sealing purely los ntawm nws tus kheej elasticity - tsis muaj springs lossis bellows. Precision-rolled superalloy hlau (GH4169 los yog GH4738) yog tsim rau hauv lub nplhaib qhib, cua sov- kho, thiab txiav los ua ib tug 0.3-0.8 hli radial preload thaum ntsia. Qhov tshwm sim yog qhov yooj yim tab sis qib siab ntawm tus kheej -energizing haum.

Qhov Zoo Tshaj Plaws
1. Tus kheej-Energizing, Caij nplooj ntoos hlav-Free Design
Lub High Temperature Alloy Seal Ring yog engineered rau turbine interstage sealing nyob rau hauv aircraft xyaw. Nws ua tiav kev sib khi nkaus xwb los ntawm nws tus kheej elasticity - tsis tas yuav tsum muaj lub tshuab nqus dej lossis lub tshuab nqus dej. Precision- dov superalloy hlau (GH4169 lossis GH4738) yog tsim rau hauv lub nplhaib qhib, cua sov- kho, thiab txiav los tsim ib lub 0.3-0.8 hli radial preload thaum ntsia. Qhov tshwm sim yog qhov yooj yim tab sis qib siab tus kheej - zog haum.
2. Siab-Khib Tightening
Lub nplhaib nta 45℃lap joint tsim. Thaum lub sijhawm ua haujlwm, cov xov xwm siab nkag mus rau hauv qhov zawj tom qab lub nplhaib, thawb nws nyuaj rau ntawm phab ntsa bore. Qhov siab dua, lub sealing nruj dua. Ntawm qhov kub thiab txias, lub nplhaib nthuav dav, kaw qhov sib txawv ntawm 0.1-0.2 hli ntawm chav tsev kub txog 0.02-0.05 hli. Qhov no tsim cov hlau tsis muaj ze li ntawm - rau- tho qhov foob, ua kom muaj txiaj ntsig zoo tshaj plaws thiab tiv thaiv kom tsis txhob tawm.
3. Siab -Tub kub oxidation Resistance
Aluminium diffusion txheej, ua raws li cov ntshav -txhaj tshuaj yttria-stabilized zirconia, txhim kho oxidation thiab corrosion kuj. Lub nplhaib tiv thaiv kev ua haujlwm tsis tu ncua ntawm 850℃thiab qhov kub siab tshaj plaws mus txog 900 degree, ua kom ntseeg tau qhov kev ua tau zoo nyob rau hauv huab cua kub.
