Ibikoresho byiza bya Ceramic kubikoresho bya serivisi bikarishye

Dukoresha kuki kugirango tuzamure uburambe.Mu gukomeza gushakisha kururu rubuga wemera gukoresha kuki. Andi makuru.
Serivise ikomeye ntigisobanuro cyemewe.Bishobora gutekerezwa nko kuvuga kumikorere aho gusimbuza valve bihenze cyangwa bigabanya ubushobozi bwibikorwa.
Harakenewe isi yose kugabanya ibiciro byumusaruro kugirango hongerwe inyungu mu nganda zose zirimo serivisi zikaze.Ibi biva kuri peteroli na gaze na peteroli na chimique kugeza kubyara ingufu za kirimbuzi n’amashanyarazi, gutunganya amabuye y'agaciro no gucukura amabuye y'agaciro.
Abashushanya naba injeniyeri barimo gukora kugirango babigereho muburyo butandukanye.Uburyo bukwiye nukwongerera igihe no gukora neza binyuze mugucunga neza ibipimo ngenderwaho nko guhagarika neza no kugenzura neza.
Kunoza umutekano nabyo bigira uruhare runini, kuko abasimbuye bake bashobora kuganisha ku musaruro utekanye. Byongeye kandi, isosiyete igerageza kugabanya ibarura ry’ibikoresho, birimo pompe na valve, hamwe n’ibisabwa bikenewe.Mu gihe kimwe, ba nyir'ibigo bategereje ibicuruzwa byinshi ku mutungo wabo.Nkigisubizo, kongera ubushobozi bwo gutunganya bivamo imiyoboro mike (ariko nini ya diameter nini) imiyoboro nibikoresho bigenda neza na metero nkeya.
Ibi birerekana ko usibye kuba bigomba kuba binini kuri diametre yagutse, ibice bya sisitemu bigomba kwihanganira igihe kirekire guhura n’ibidukikije bikabije kugirango bigabanye gukenera serivisi no kuyisimbuza.
Ibigize, harimo na valve numupira, bigomba kuba bikomeye kugirango bihuze ibyifuzo byifuzwa, ariko kandi bigatanga ubuzima bwagutse bwa serivisi.Nyamara, ikibazo gikomeye mubisabwa byinshi nuko ibice byicyuma bigeze kumipaka yubushobozi bwabo.Ibi byerekana ko abashushanya bashobora shakisha ubundi buryo bwibikoresho bitari ibyuma, cyane cyane ibikoresho byubutaka, kugirango usabe 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 nkibintu bidashobora kwihanganira ibintu birashobora kunanirwa bikabije.Ubukomere bwibikoresho bya ceramic bisobanurwa nkurwanya gukwirakwizwa kwinshi.Mu bihe bimwe na bimwe birashobora gupimwa hakoreshejwe uburyo bwa indentation, bikavamo agaciro gakomeye. Gukoresha kimwe -uruhande rwibiti bitanga ibipimo nyabyo.
Imbaraga zifitanye isano no gukomera, ariko zerekeza ku ngingo imwe aho ibintu byananiranye bikabije iyo impagarara zashyizwe mu bikorwa.Bikunze kwitwa "modulus yo guturika" kandi bipimwa no gufata ingingo eshatu cyangwa ingingo enye zingirakamaro gupima ku kizamini. Ikizamini cy'amanota atatu gitanga 1% agaciro karenze ikizamini cy'amanota ane.
Mugihe ubukana bushobora gupimwa kumunzani zitandukanye zirimo Rockwell na Vickers, igipimo cya microhardness ya Vickers gikwiranye nibikoresho bya ceramic bigezweho.Ububabare buratandukanye bitewe no kwihanganira kwambara.
Mubibaya bikora muburyo bwa cycle, umunaniro nikibazo gikomeye bitewe no gukomeza gufungura no gufunga valve.Umunaniro ninzitizi yimbaraga zirenze aho ibintu bikunda kunanirwa munsi yimbaraga zisanzwe zisanzwe.
Kurwanya ruswa biterwa n’ibidukikije bikora hamwe n’itangazamakuru ririmo ibikoresho.Ibikoresho byinshi byateye imbere bya ceramic biruta ibyuma muri kariya gace, usibye ibikoresho bimwe na bimwe bishingiye kuri zirconi “bitesha agaciro hydrothermally” iyo bihuye nubushyuhe bwo hejuru.
Igice cya geometrie, coefficente yo kwagura ubushyuhe, ubushyuhe bwumuriro, ubukana, nimbaraga byose bigira ingaruka kumashanyarazi. Aka ni agace gateza imbere ubushyuhe bwinshi nubukomere, bityo rero, ibice byicyuma bikora neza.Nyamara, iterambere mubikoresho byubutaka ubu tanga urwego rwemewe rwo guhangana nubushyuhe bwumuriro.
Ubukorikori buhanitse bwakoreshejwe imyaka myinshi kandi burazwi cyane mubashakashatsi bokwizerwa, abashinzwe inganda hamwe nabashushanya valve basaba gukora cyane nagaciro. Ukurikije ibisabwa byihariye bisabwa, hariho formulaire zitandukanye zitandukanye zikwiranye ninganda zitandukanye.Nyamara, ceramique enye zateye imbere by'akamaro mubijyanye na serivise zikomeye za serivise, kandi zirimo karbide ya silicon (SiC), nitride ya silicon (Si3N4), alumina na zirconia. Ibikoresho byumupira wa valve na valve byatoranijwe hashingiwe kubisabwa byihariye bisabwa.
Hariho uburyo bubiri bwingenzi bwa zirconi bukoreshwa mubibaya bifite coefficient imwe yo kwaguka kwubushyuhe no gukomera nkibyuma.Magnesia igice cya zirconiya gihamye igice (Mg-PSZ) gifite imbaraga nyinshi zo guhangana nubushyuhe bukabije, mugihe yttria tetragonal zirconia polycrystalline (Y-TZP ) birakomeye ariko bikunda kwangirika kwa hydrothermal.
Silicon Nitride (Si3N4) iraboneka muburyo butandukanye.Gas Pressure Sintered Silicon Nitride (GPPSN) nikintu gikoreshwa cyane mubikoresho bya valve na valve, bitanga ubukana nimbaraga nyinshi, imbaraga zidasanzwe zo guhangana nubushyuhe hamwe nubushyuhe bwumuriro hiyongereyeho ubukana buringaniye. Byongeye kandi, Si3N4 itanga umusemburo ukwiye wa zirconi mubushyuhe bwo hejuru bwikirere, bikarinda kwangirika kwamazi.
Bitewe ningengo yimari idahwitse, abasobanuzi barashobora guhitamo muri SiC cyangwa Alumina.Ibikoresho byombi bifite ubukana bwinshi, ariko ntibikomeye kuruta zirconi cyangwa nitride ya silicon.Ibi byerekana ko ibyo bikoresho bikwiranye nibisabwa bihamye nka valve bushing n'intebe, aho guhitamo imipira ihangayikishije cyane cyangwa disiki.
Ibikoresho bya ceramic bigezweho bifite ubukana buke nimbaraga zisa nkibikoresho byuma bikoreshwa mugukoresha serivise zikomeye, harimo icyuma cya chromium (CrFe), karbide ya tungsten, Hastelloy na Stellite.
Porogaramu zikaze zirimo gukoresha ikoreshwa ryizunguruka nka kinyugunyugu, trunnions, imipira ireremba imipira n'amasoko.Mu bikorwa nkibi, Si3N4 na zirconia bitanga imbaraga zo guhangana nubushyuhe bwumuriro, ubukana nimbaraga zo guhangana nibidukikije bikaze. Bitewe no gukomera no kurwanya ruswa. y'ibikoresho, ubuzima bwa serivisi bwibigize burenze inshuro nyinshi ugereranije nibyuma.Izindi nyungu zirimo imikorere iranga valve hejuru yubuzima bwayo bwingirakamaro, cyane cyane mubice bikomeza ubushobozi bwo gufunga no kugenzura.
Ibi bigaragazwa no gushyira mu bikorwa umupira wa mm 65 (2,6 in) valve kynar / RTFE umupira na liner byerekanwe na 98% acide sulfurike na ilmenite, ihindurwamo pigment ya titanium oxyde. Imiterere yibikorwa byikigereranyo bivuze ko ibyo bice bishobora kumara ibyumweru bitandatu.Nyamara, ukoresheje umupira wa valve trim (Igicapo 1) wakozwe muri Nilcra! ", magnesia nyirizina yihariye igice cya zirconiya (Mg-PSZ) itanga ubukana buhebuje no kurwanya ruswa, itanga serivise yimyaka itatu idahagarara nta nimwe kwambara.
Mububiko bwumurongo burimo inguni, trottle cyangwa isi yose, zirconi na nitride ya silicon ikwiranye no gucomeka no kwicara kubera imiterere "yicaye ikomeye" yibicuruzwa. Nkuko bimeze, okiside ya aluminiyumu irashobora gukoreshwa mumirongo imwe n'imwe. cyo gufunga birashobora kugerwaho muguhuza imipira yo gusya kuntebe ya valve.
Kumashanyarazi ya valve, harimo pompe ya valve, inleti na outlet, cyangwa ibihuru byumubiri, kimwe mubikoresho bine byingenzi byingenzi byubutaka birashobora gukoreshwa bitewe nibisabwa. ubuzima bwibicuruzwa.
Fata nk'urugero, ikinyugunyugu cya DN150 gikoreshwa mu ruganda rwa bauxite rwo muri Ositaraliya.Ibintu byinshi bya silika biri mu bitangazamakuru bishobora gutera kwambara cyane ku gihuru cya valve.Imirongo yambere na disiki byakozwe muri 28% bya CrFe kandi byakoreshwaga gusa Ibyumweru 8 kugeza ku 10.Nyamara, hamwe na valve ikozwe muri Nilcra! "Zirconiya (Igishusho 2), ubuzima bwa serivisi bwiyongereye bugera ku byumweru 70.
Kubera ubukana n'imbaraga zabo, ububumbyi bukora neza mubikorwa byinshi bya valve.Nyamara, ni ubukana bwabo hamwe no kurwanya ruswa bigira uruhare mu kuramba kwa valve.Ibi na byo bigabanya ibiciro byubuzima muri rusange kugabanya igihe cyo kugabanya ibice bisimburwa, kugabanya igishoro gikora no kubara, kugabanya gufata intoki, no guteza imbere umutekano binyuze mumaraso make.
Gukoresha ibikoresho bya ceramic mumashanyarazi yumuvuduko mwinshi bimaze igihe kinini mubibazo byingenzi kuko iyi mibande ikorerwa imitwaro myinshi ya axial cyangwa torsional.Nyamara, abakinyi bakomeye mukibuga ubu barimo gutegura imipira yimipira kugirango barusheho kubaho neza.
Indi mbogamizi ikomeye ni ingano. Intebe nini n'umupira munini (Ishusho 3) ikomoka muri magnesia igice cya zirconi itajegajega ni DN500 na DN250.Nyamara.
Nubwo ibikoresho byubutaka byagaragaye ko ari amahitamo akwiye, amabwiriza yoroshye agomba gukurikizwa kugirango arusheho gukora neza. Ibikoresho byubutaka bigomba gukoreshwa mbere gusa mugihe bibaye ngombwa kugabanya ibiciro. hanze.
Ikintu icyo ari cyo cyose gishobora kwaguka cyoguhuza ubushyuhe kigomba gusuzumwa mugihe cyo gushushanya.Kugabanya imihangayiko ya hop, ni ngombwa kugumisha ceramic hanze, ntabwo ari imbere. Ubwanyuma, hakenewe kwihanganira geometrike no kurangiza hejuru bigomba kwitabwaho neza, kuko ibi irashobora kongeramo ikiguzi cyingenzi kandi kidakenewe.
Mugukurikiza aya mabwiriza nuburyo bwiza bwo gutoranya ibikoresho no guhuza nabatanga isoko kuva umushinga watangira, igisubizo cyiza kirashobora kugerwaho kuri buri serivisi ikomeye.
