Ibikoresho bya ceramic bigezweho kubikorwa bya serivise zikaze

Nta bisobanuro bya serivisi byemewe. Irashobora gufatwa nkikiguzi kinini cyo gusimbuza valve cyangwa imiterere yakazi igabanya ubushobozi bwo gutunganya. Isi yose ikeneye kugabanya ibiciro byumusaruro kugirango habeho kuzamura inyungu zinzego zose zifite uruhare runini muri serivisi mbi. Ibi biva kuri peteroli na gaze, ibikomoka kuri peteroli kugeza ingufu za kirimbuzi no kubyara ingufu, gutunganya amabuye y'agaciro no gucukura amabuye y'agaciro. Abashushanya n'abashakashatsi bagerageza kugera kuriyi ntego muburyo butandukanye. Uburyo bukwiye cyane nukwongerera igihe no gukora neza mugucunga neza ibipimo ngenderwaho (nko guhagarika neza no kugenzura neza). Kunoza umutekano nabyo bigira uruhare runini, kuko kugabanya umubare wabasimbuye bishobora kuganisha ku musaruro utekanye. Byongeye kandi, isosiyete ikora kugirango igabanye ibikoresho (harimo pompe na valve) ibarura kandi risabwa kujugunywa. Muri icyo gihe, abafite ibikoresho biteze ko ibintu byinshi biva mu mutungo wabo. Kubwibyo, kongera ubushobozi bwo gutunganya bizavamo imiyoboro mike (ariko nini ya diameter nini) imiyoboro nibikoresho nibikoresho bike kumurongo umwe. Ibi birerekana ko, usibye kuba ugomba gukoresha ibice binini bya sisitemu kugiti cya diametre yagutse, birakenewe kandi kwihanganira kumara igihe kinini uhura nibidukikije bikabije kugirango ugabanye serivisi no kubisabwa. Ibigize birimo imipira na imipira ya valve bigomba kuba bikomeye kugirango bihuze ibyifuzo, ariko birashobora no kongera ubuzima bwabo. Nyamara, ikibazo nyamukuru hamwe nibisabwa byinshi nuko ibice byicyuma bigeze kumipaka yabyo. Ibi byerekana ko abashushanya bashobora kubona ubundi buryo bwibikoresho bitari ibyuma mubisabwa, cyane cyane ibikoresho byubutaka. Ibipimo bisanzwe bisabwa kugirango ukore ibice mubihe bigoye harimo kurwanya ubushyuhe bwumuriro, kurwanya ruswa, kurwanya umunaniro, gukomera, imbaraga, no gukomera. Kwihangana nikintu cyingenzi, kuko ibice bitarwanya imbaraga birashobora kunanirwa bikabije. Ubukomezi bwibikoresho bya ceramic bisobanurwa nkurwanya gukwirakwizwa. Rimwe na rimwe, birashobora gupimwa hakoreshejwe uburyo bwa indentation kugirango ubone agaciro gakomeye. Gukoresha uruhande rumwe rwo gutemagura birashobora gutanga ibisubizo nyabyo byo gupima. Imbaraga zifitanye isano no gukomera, ariko bivuga ingingo imwe aho ibintu byangiritse bikabije iyo hakoreshejwe stress. Bikunze kwitwa "modulus yo guturika" kandi iboneka mugupima imbaraga zingingo eshatu cyangwa enye zunamye ku nkoni yikizamini. Agaciro k'ibizamini bitatu-ni hejuru ya 1% kurenza agaciro k'ikizamini cy'amanota ane. Nubwo umunzani mwinshi urimo igeragezwa rya Rockwell hamwe nugupima ubukana bwa Vickers birashobora gukoreshwa mugupima ubukana, igipimo cya microhardness ya Vickers kirakwiriye cyane kubikoresho byubutaka bwateye imbere. Ubukomezi burahinduka ugereranije no kwambara ibintu. Mubibaya bikora muburyo bwa cycle, umunaniro nicyo gihangayikishije cyane kubera guhora gufungura no gufunga valve. Umunaniro ni urwego rwimbaraga. Kurenga iyi mbago, ibikoresho bikunda kunanirwa munsi yimbaraga zisanzwe zunama. Kurwanya ruswa biterwa nibidukikije bikora hamwe nuburyo bukubiyemo ibikoresho. Usibye "hydrothermal degradation", ibikoresho byinshi byubutaka byateye imbere biruta ibyuma muriki gice, kandi ibikoresho bimwe na bimwe bishingiye kuri zirconi bizagira "hydrothermal degradation" nyuma yo guhura nubushyuhe bwo hejuru. Uburinganire bwa geometrie, coefficente yo kwagura ubushyuhe, ubushyuhe bwumuriro, ubukana nimbaraga zibigize bigira ingaruka kumashanyarazi. Aka gace korohereza ubushyuhe bwinshi nubukomere, kuburyo ibyuma bishobora gukora neza. Nyamara, iterambere mubikoresho byubutaka noneho bitanga urwego rwemewe rwo guhangana nubushyuhe bwumuriro. Ubukorikori buhanitse bwakoreshejwe imyaka myinshi kandi burazwi cyane mubashinzwe kwizerwa, abashinzwe inganda n’abashushanya valve bakeneye imikorere ihanitse kandi ifite agaciro gakomeye. Ukurikije ibisabwa byihariye bisabwa, birakwiriye muburyo butandukanye mubikorwa bitandukanye. Nyamara, ibumba bine byateye imbere bifite akamaro kanini mubijyanye no gufata neza ibyuma, harimo karubide ya silicon (SiC), nitride ya silicon (Si3N4), alumina na zirconiya. Ibikoresho byumupira wa valve na valve byatoranijwe ukurikije ibisabwa byihariye bisabwa. Umuyoboro ukoresha uburyo bubiri bwingenzi bwa zirconi, bufite coefficente yo kwagura ubushyuhe hamwe no gukomera nkibyuma. Magnesium oxyde igice cya zirconiya itajegajega (Mg-PSZ) ifite imbaraga nyinshi zo guhangana nubushyuhe bukabije hamwe nubukomere, mugihe yttria tetragonal zirconia polycrystalline (Y-TZP) irakomeye, ariko irashobora kwangirika kwa hydrothermal. Nitride ya Silicon (Si3N4) ifite formulaire zitandukanye. Umuvuduko wa gazi yacuzwe na silicon nitride (GPPSN) nikintu gikoreshwa cyane mubikoresho bya valve. Usibye ubukana bwacyo buringaniye, ifite kandi imbaraga nimbaraga nyinshi, guhangana nubushyuhe bwiza bwumuriro hamwe nubushyuhe bwumuriro. Mubyongeyeho, mubushuhe bwo hejuru bwibidukikije, Si3N4 irashobora gusimbuza zirconi kugirango irinde kwangirika kwamazi. Hamwe ningengo yimari ikaze, intumbero irashobora guhitamo muri SiC cyangwa alumina. Ibikoresho byombi bifite ubukana bwinshi, ariko ntibigoye kuruta zirconi cyangwa nitride ya silicon. Ibi birerekana ko ibikoresho bikwiranye cyane na progaramu ya static yibikoresho, nkibikoresho bya valve hamwe nintebe za valve, kuruta imipira ya valve cyangwa disiki ziterwa nimpungenge nyinshi. Ugereranije nibikoresho byuma bikoreshwa mugusaba valve (harimo ferrochrome (CrFe), karbide ya tungsten, Hastelloy na Stellite), ibikoresho bya ceramic bigezweho bifite ubukana buke nimbaraga zisa. Gusaba serivisi zisaba gukoresha ikoreshwa ryizunguruka, nk'ibinyugunyugu, trunnions, imipira ireremba hamwe n'amasoko. Mubikorwa nkibi, Si3N4 na zirconia bifite ubushyuhe bwumuriro, ubukana nimbaraga, kandi birashobora guhuza nibidukikije bisabwa cyane. Bitewe no gukomera no kurwanya ruswa yibikoresho, ubuzima bwa serivisi bwikubye inshuro nyinshi ubw'icyuma. Izindi nyungu zirimo ibiranga imikorere hejuru yubuzima bwa valve, cyane cyane mubice bikomeza ubushobozi bwo kugenzura no kugenzura. Ibi byagaragaye mugihe cya 65mm (2,6 inch) valve kynar / RTFE umupira na liner byerekanwe na 98% acide sulfurike hiyongereyeho ilmenite, ilmenite ihinduka pigment ya titanium. Imiterere yibitangazamakuru isobanura ko ubuzima bwibi bice bushobora kumara ibyumweru bitandatu. Nyamara, ikoreshwa rya spherical valve trim (oxyde ya magnesium oxyde igice cya stabilisation zirconia (Mg-PSZ)) yakozwe na Nilcra ™ (Ishusho 1) ifite ubukana buhebuje kandi irwanya ruswa kandi imaze imyaka itatu itangwa. Serivise yigihe gito, nta kwambara kugaragara. Muburyo bwumurongo (harimo impande zinguni, imitsi ya trottle cyangwa isi yose), kubera "intebe ikomeye" iranga ibyo bicuruzwa, zirconiya na nitride ya silicon ikwiranye nu byuma byombi byacometse hamwe nintebe za valve. Mu buryo nk'ubwo, alumina irashobora gukoreshwa mumirongo imwe n'imwe. Binyuze mumupira uhuza impeta yintebe, urwego rwo hejuru rwo gufunga rushobora kugerwaho. Kububiko bwa valve, harimo na spol valve, inlet na outlet cyangwa valve umubiri bushing, ikintu icyo aricyo cyose mubikoresho bine byingenzi byubutaka birashobora gukoreshwa ukurikije ibisabwa. Ubukomere bukabije hamwe no kurwanya ruswa yibikoresho byagaragaye ko ari ingirakamaro mubijyanye nibikorwa byubuzima nubuzima bwa serivisi. Fata urugero rwa DN150 ikinyugunyugu ikoreshwa mu ruganda rwa bauxite rwo muri Ositaraliya. Ibintu byinshi bya silika murwego rwo hagati bitera urwego rwo hejuru rwo kwambara kuri valve bushings. Disiki ya liner na valve yakoreshejwe muburyo bwambere yakozwe muri 28% ya CrFe kandi yamaze ibyumweru umunani kugeza icumi. Ariko, kubera kwinjiza indangagaciro zakozwe na Nilcra ™ zirconia (Ishusho 2), ubuzima bwa serivisi bwongerewe kugeza ku byumweru 70. Bitewe nubukomezi nimbaraga zayo, ububumbyi bukora neza mubikorwa byinshi bya valve. Nyamara, gukomera kwabo no kurwanya ruswa bifasha kwagura ubuzima bwa valve. Na none, ibi bigabanya ikiguzi cyubuzima bwose mugabanya igihe cyo kugabanya ibice byasimbuwe, kugabanya igishoro cyakazi no kubara, gukoresha intoki nkeya, hamwe no kurushaho kunoza umutekano binyuze mumeneka yamenetse. Kumwanya muremure, ikoreshwa ryibikoresho byubutaka mumashanyarazi yumuvuduko mwinshi byabaye kimwe mubibazo byingenzi, kubera ko iyi mibande ikorerwa imitwaro myinshi ya axial cyangwa torsional. Ariko, abakinyi bakomeye muriki gice barimo gutegura imipira ya valve itezimbere ubuzima bwumuriro. Ibindi bigarukira ni ubunini. Ingano yintebe nini nini nini nini (Ishusho 3) yakozwe na magnesia igice cya zirconi gihamye igice ni DN500 na DN250. Nyamara, abantu benshi basobanura neza bahitamo gukoresha ububumbyi kugirango bakore ibice ibipimo bitarenze ibyo bipimo. Nubwo ibikoresho byubutaka byaragaragaye ko ari amahitamo akwiye, haracyariho amabwiriza yoroshye agomba gukurikizwa kugirango ibikorwa byabo bigerweho. Ibikoresho byubutaka bigomba gukoreshwa mbere gusa niba bikenewe kugabanya ibiciro. Haba imbere no hanze bigomba kwirinda inguni zikarishye no guhangayikishwa cyane. Ikintu cyose gishobora kwaguka cyumuriro kidahuye kigomba gusuzumwa mugihe cyicyiciro. Kugirango ugabanye impagarara, ni ngombwa kugumisha ceramic hanze aho kuba imbere. Hanyuma, gukenera kwihanganira geometrike no kurangiza hejuru bigomba gusuzumwa neza, kuko ubwo bworoherane bushobora kongera cyane ibiciro bitari ngombwa. Mugukurikiza aya mabwiriza nibikorwa byiza muguhitamo ibikoresho no guhuza nabatanga isoko kuva umushinga watangira, igisubizo cyiza kirashobora kugerwaho kuri buri serivisi isaba serivisi. Aya makuru yabonetse, asubirwamo kandi ahindurwa mubikoresho byatanzwe na Morgan Advanced Materials. Morgan Ibikoresho Byambere-Ubukorikori bwa tekinike. (28 Ugushyingo 2019).
