Ibikoresho bya ceramic bigezweho byo gusaba serivisi

Dukoresha kuki kugirango twongere uburambe bwawe. Mugukomeza gushakisha kururu rubuga, wemera gukoresha kuki. Andi makuru. Nta bisobanuro byemewe bya serivisi zikomeye. Birashobora kumvikana nkibikorwa bikora aho igiciro cyo gusimbuza valve ari kinini cyangwa ubushobozi bwo gutunganya bukagabanuka. Harakenewe isi yose kugabanya ibiciro byumusaruro kugirango hongerwe inyungu mumirenge yose igira uruhare muri serivisi mbi. Ibi biva kuri peteroli na gaze na peteroli-chimique 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). Gutezimbere umutekano nabyo bigira uruhare runini, kuko kugabanya gusimburwa bishobora kuganisha ku musaruro utekanye. Byongeye kandi, isosiyete irimo gukora kugirango igabanye ibikoresho, harimo pompe na valve, hamwe n’ibisabwa. Muri icyo gihe, abafite ibikoresho biteze impinduka nini mumitungo yabo. Nkigisubizo, kongera ubushobozi bwo gutunganya bivamo imiyoboro mike nibikoresho (ariko diameter nini) nibikoresho bike kubicuruzwa bimwe. Ibi birerekana ko usibye kuba binini kuba binini bya diameter nini, igice kimwe cya sisitemu nacyo gikeneye kwihanganira igihe kirekire cyibidukikije bikabije kugirango bigabanye gukenera serivisi no kuyisimbuza. Ibigize birimo imipira hamwe nudupira twa valve bigomba kuba bikomeye kugirango uhuze ibyifuzo, ariko birashobora no gutanga ubuzima burebure. Nyamara, ikibazo gikomeye hamwe nibisabwa byinshi nuko ibice byicyuma bigeze kumipaka yimikorere yabo. Ibi byerekana ko abashushanya bashobora kubona ubundi buryo bwibikoresho bitari ibyuma, cyane cyane ibikoresho byubutaka, kubisaba serivisi. Ibipimo bisanzwe bisabwa kugirango ukore ibice mubihe bikomeye bya serivisi 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, bikavamo indangagaciro ndende. Gukoresha urumuri rumwe rwo gutemagura birashobora gutanga ibipimo nyabyo. Imbaraga zifitanye isano no gukomera, ariko bivuga ingingo imwe aho ibintu byananiranye bikabije mugihe impagarara zashyizwe mubikorwa. Bikunze kwitwa "modulus yo guturika" kandi bipimwa mugukora ibipimo bitatu cyangwa bine bipima imbaraga zipima inkoni yikizamini. Ikizamini cy'amanota atatu gitanga agaciro kari hejuru ya 1% kuruta ikizamini cy'amanota ane. Nubwo ubukana bushobora gupimwa nubunzani butandukanye burimo Rockwell na Vickers, igipimo cya microhardness ya Vickers kirakwiriye cyane kubikoresho byubutaka byateye imbere. Ubukomezi buragereranywa nuburyo bwo kwambara bwibikoresho. Muri valve ikora muburyo bwa cycle, umunaniro nikibazo gikomeye bitewe no gukomeza gufungura no gufunga valve. Umunaniro nimbaraga zingana, ibirenze ibyo ibikoresho bizananirana munsi yimbaraga zisanzwe zunamye. Kurwanya ruswa biterwa nibidukikije bikora hamwe nuburyo burimo ibikoresho. Muri uru rwego, ibikoresho byinshi byubutaka byateye imbere bifite ibyiza kurenza ibyuma, usibye "hydrothermal degradation", bibaho mugihe ibikoresho bimwe na bimwe bishingiye kuri zirconi bihuye nubushyuhe bwo hejuru. Igice cya geometrie, coefficente yo kwagura ubushyuhe, ubushyuhe bwumuriro, ubukana nimbaraga bigira ingaruka kumashanyarazi. Aka ni agace 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 mubashakashatsi bokwizerwa, abashinzwe inganda hamwe nabashushanya valve bakeneye imikorere myiza nagaciro. Ukurikije ibisabwa byihariye bisabwa, hariho uburyo butandukanye bwihariye bukwiranye ninganda zitandukanye. Nyamara, ibintu bine byateye imbere bifite akamaro kanini mubijyanye na serivise zikomeye. Harimo karbide ya silicon (SiC), nitride ya silicon (Si3N4), alumina na zirconiya. Ibikoresho byumupira wa valve na valve byatoranijwe ukurikije ibisabwa byihariye bisabwa. Uburyo bubiri bwingenzi bwa zirconi bukoreshwa mubibaya, byombi bifite coefficente imwe yo kwagura ubushyuhe no gukomera nkibyuma. Oxide ya Magnesium igice cya zirconiya (Mg-PSZ) ifite imbaraga nyinshi zo guhangana nubushyuhe bukabije hamwe nubukomere, mugihe yttria tetragonal zirconia polycrystalline (Y-TZP) irakomeye kandi ikomeye, ariko irashobora kwangirika kwamazi. 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, itanga kandi imbaraga nimbaraga nyinshi, guhangana nubushyuhe bwiza bwumuriro hamwe nubushyuhe bwumuriro. Mubyongeyeho, mubushuhe bwo hejuru bwibidukikije, Si3N4 nigisimburwa gikwiye cya zirconi, gishobora kwirinda kwangirika kwa hydrothermal. Iyo ingengo yimari idahwitse, abayisobanura barashobora guhitamo silicon karbide cyangwa alumina. Ibikoresho byombi bifite ubukana bwinshi, ariko ntibikomeye kuruta zirconi cyangwa nitride ya silicon. Ibi birerekana ko ibikoresho bikwiranye cyane na static yibikoresho, nkibikoresho bya valve hamwe nintebe za valve, aho kuba imipira ya valve cyangwa disiki ziterwa nimpungenge nyinshi. Ugereranije nibikoresho byuma bikoreshwa mugukoresha serivise zikaze (harimo ferrochrome (CrFe), karbide ya tungsten, Hastelloy na Stellite), ibikoresho bya ceramic bigezweho bifite ubukana buke nimbaraga zisa. Porogaramu zikomeye zirimo gukoresha ikoreshwa ryizunguruka, nkibinyugunyugu, trunnion, imipira ireremba, hamwe nisoko. Mubisabwa nkibi, Si3N4 na zirconia byerekana ubushyuhe bwumuriro, ubukana nimbaraga zo guhuza nibidukikije bisabwa cyane. Bitewe no gukomera no kurwanya ruswa yibikoresho, ubuzima bwa serivisi bwibice bwiyongera inshuro nyinshi ugereranije nibyuma. Izindi nyungu zirimo imikorere iranga valve mubuzima bwayo, cyane cyane mubice bikomeza ubushobozi bwo gufunga no kugenzura. Ibi bigaragarira mubisabwa aho mm 65 (2,6 in) ya valve kynar / RTFE umupira na liner bahura na 98% acide sulfurike na ilmenite, ihindurwamo pigment ya titanium. Imiterere yibitangazamakuru isobanura ko ubuzima bwibi bice bushobora kumara ibyumweru bitandatu. Ariko, gukoresha imipira yimipira yakozwe na Nilcra ™ (Igicapo 1), ni oxyde ya magnesium oxyde igice cya zirconi (Mg-PSZ) itajegajega igice, ifite ubukana buhebuje kandi irwanya ruswa, kandi irashobora gutanga imyaka itatu yumurimo udahagarara nta kintu kiboneka. kwambara no kurira. Mububiko bwumurongo, burimo impande zinguni, imitsi ya trottle cyangwa isi yose, bitewe n "" ikimenyetso gikomeye "kiranga ibyo bicuruzwa, zirconi na nitride ya silicon birakwiriye gucomeka hamwe nintebe za valve. Mu buryo nk'ubwo, alumina irashobora gukoreshwa kuri gaseke na kage. Muguhuza imipira yo gusya ku ntebe ya valve, urwego rwo hejuru rwo gufunga rushobora kugerwaho. Kumurongo wa valve, harimo intanga ya valve, inlet na outlet cyangwa valve umubiri utondekanye, kimwe murimwe mubikoresho bine byingenzi byubutaka birashobora gukoreshwa ukurikije ibisabwa. Ubukomere bukabije hamwe no kurwanya ruswa yibikoresho byagaragaye ko ari ingirakamaro mubikorwa byimikorere nubuzima bwa serivisi. Fata urugero rwa DN150 ikinyugunyugu ikoreshwa mu ruganda rwa bauxite rwo muri Ositaraliya. Ibintu byinshi bya silika murwego rwo hagati bitanga urwego rwo hejuru rwo kwambara kumurongo wa valve. Gasketi na disiki byakoreshejwe bwa mbere bikozwe muri 28% ya CrFe kandi bimara ibyumweru umunani kugeza ku icumi gusa. Nyamara, hamwe na valve ikozwe muri Nilcra ™ zirconia (Ishusho 2), ubuzima bwa serivisi bwiyongereye kugeza ku byumweru 70. Bitewe nubukomezi nimbaraga zayo, ububumbyi bukora neza mubikorwa byinshi bya valve. Nyamara, gukomera kwabo no kurwanya ruswa bifasha kongera ubuzima bwa serivisi ya valve. Ibi na byo bigabanya ikiguzi cyubuzima bwose mugabanya igihe cyo kugabanya ibice bisimburwa, kugabanya igishoro gikora no kubara, gukoresha intoki ntoya, no kunoza umutekano mukugabanya kumeneka. Kuva kera, ikoreshwa ryibikoresho byubutaka mumashanyarazi yumuvuduko mwinshi byabaye kimwe mubibazo nyamukuru, kubera ko iyi mibande ikorerwa imitwaro myinshi ya axial cyangwa torsional. Ariko, abakinyi bakomeye muriki gice barimo gutegura imipira ya valve kugirango bongere ubuzima bwumuriro. Ibindi bigarukira ni igipimo. Ingano yintebe nini nini nini nini (Ishusho 3) ikomoka muri zirconi itajegajega igice hamwe na oxyde ya magnesium ni DN500 na DN250. Nyamara, abantu benshi basobanura kuri ubu bahitamo ububumbyi bwibigize munsi yubunini. Nubwo ibikoresho byubutaka byaragaragaye ko ari amahitamo akwiye, amabwiriza yoroshye agomba gukurikizwa kugirango ibikorwa byabo bigerweho. Ibikoresho byubutaka bigomba gukoreshwa gusa mugihe ibiciro bigomba kubikwa byibuze. Inguni zikarishye hamwe no guhangayika bigomba kwirindwa haba imbere no hanze. Ikintu cyose gishobora kwaguka cyumuriro kidahuye kigomba gusuzumwa mugihe cyicyiciro. Kugirango ugabanye imihangayiko, ceramic igomba kubikwa hanze, ntabwo imbere. Hanyuma, gukenera kwihanganira geometrike no kurangiza hejuru bigomba gusuzumwa neza, kuko bizamura cyane ibiciro bitari ngombwa. Mugukurikiza aya mabwiriza hamwe nuburyo bwiza bwo guhitamo ibikoresho no guhuza nabatanga isoko kuva umushinga watangira, igisubizo cyiza kirashobora kugerwaho kuri buri serivisi isaba serivisi.
