1.Inkoni yo gusudira igomba guhora yumye mugihe ikoreshwa. Ubwoko bwa calcium titanate bugomba gukama kuri 150′C kumasaha 1, naho ubwoko bwa hydrogène buke bwumishwa kuri 200-250 ℃ kumasaha 1 (kumisha ntibizongera kubaho inshuro nyinshi, bitabaye ibyo uruhu rworoshye kumenagura no gukuramo) kugirango wirinde uruhu rwo gusudira uruhu, amavuta yumuti hamwe nundi mwanda, kugirango wirinde kongera imyuka ya karubone yo gusudira no kugira ingaruka kumiterere yo gusudira.
2.Mu gihe cyo gusudiraibyuma bidafite ingeseimiyoboro ya pipe, karbide igwa nubushyuhe bwinshi, bigabanya kwangirika hamwe nubukanishi.
3.Ibikoresho bikomereye muri Amerika bya flange ya chrome idafite ibyuma bya flange nyuma yo gusudira ni binini kandi byoroshye gucika. Niba ubwoko bumwe bwa chromium idafite ibyuma bya electrode (G202, G207) bikoreshwa mugusudira, gushyushya hejuru ya 300 ℃ no kuvura buhoro buhoro hafi 700 ℃ nyuma yo gusudira. Niba gusudira bidashobora gukorerwa ubushyuhe nyuma yo gusudira, hazatoranywa icyuma cya elegitoronike (A107, A207).
4.Ku byuma bidafite ingese, ingano ikwiye yibintu bihamye nka Ti, Nb na Mo byongeweho kugirango birusheho kwangirika no gusudira. Gusudira ni byiza kurenza ibya chrome idafite ibyuma. Iyo ubwoko bumwe bwa chrome butagira ibyuma bya flange yo gusudira (G302, G307), hakoreshejwe ubushyuhe hejuru ya 200 ℃ no gushyushya hafi 800 ℃ nyuma yo gusudira. Niba gusudira bidashobora kuvurwa ubushyuhe, hazatoranywa icyuma cya electrode (A107, A207).
5.Icyuma kidafite ingese imiyoboro ya pipe hamwe na butt-welding flange yo gusudira ifite imiti irwanya ruswa kandi irwanya imiti, kandi ikoreshwa cyane mubikorwa bya shimi, ifumbire, peteroli n’imashini.
6.Mu rwego rwo kwirinda kwangirika kw'amaso ku jisho biterwa no gushyushya igifuniko cya flange, umuyoboro wo gusudira ntugomba kuba munini cyane, hafi 20% ugereranije n'uw'icyuma cya karubone electrode, arc ntigomba kuba ndende cyane, no gukonjesha hagati-ntibigomba gutinda, kandi isaro rifunguye yo gusudira igomba guhitamo.
Icyuma cya karubone flange ikoreshwa muburyo budasanzwe, bityo rero isaba yoroshye, ihindagurika, ikomeretsa, torsional nibindi biranga ibikoresho. Irashobora gukoreshwa munsi yumuvuduko mwinshi utagoretse. Kuberako ibyuma bya karubone bifite burr nke, imbaraga zayo zo guterana nazo ni nto cyane, kandi irashobora gukoreshwa cyane mubikoresho.
Byongeye kandi, ibyuma bya karubone bigomba gukorwa hakurikijwe ibipimo by’Ubushinwa cyangwa bijyanye n’inganda. Ntuzigere ukoresha ibikoresho bitujuje ibisabwa kugirango ubikore. Kurenza uko udashobora guca inguni kubunini, izi nzira zamahirwe azaganisha kubicuruzwa bito kandi bitujuje ibyangombwa, bizatera kunanirwa muri sisitemu yose yubufaransa, ndetse bitera igihombo cyubukungu bwumutungo nabahitanwa nizindi mpanuka zihamye.
Umuntu wese wigeze yumva ibyuma bya karubone azi ko guta ibintu bigoye. Ukurikije ibikoresho byayo, ibyuma bya karubone nabyo bitandukanye nibindi byuma, kandi imikorere yayo iruta iy'ibyuma. Icyerekezo cyiza rero gikozwe mubyuma bya karubone, ni ukuvuga ibyo bita ibyuma bya karubone. Usibye karubone, ibyuma bya karubone muri rusange birimo silikoni nkeya, manganese, sulfure, fosifore nibindi bintu, bityo ikaba ifite umwihariko mubikoresho.
Uburyo bwo gupima ibyuma bya karubone flange hamwe nakazi ko gutegura mbere yo gupima bizatangizwa muri make na editor.
1.Mu gihe cyo gupima, abantu batatu bagomba gutegurwa, babiri muribo barapima, umwe aragenzura kandi yuzuza ifishi. Niba nta kintu na kimwe cyo gukoresha Caliper yo hanze hamwe nicyuma cyuma, Caliper irashobora gukoreshwa nkigikoresho cyo gupima. Gupima nakazi keza kandi gisabwa kugirango ushyireho ibikoresho. Ibipimo n'inyandiko bigomba gutegurwa neza, kandi ifishi igomba kuzuzwa neza kandi neza. Mubikorwa nyirizina byo gupima. Kugira ngo dufatanye, dukwiye gushobora gufatanya no gukoresha dukurikije amahame meza.
2. Ukurikije umwanya wa flange nini mbere yo gupimwa, igishushanyo mbonera hamwe numubare wa flange nini y'ibikoresho bigomba kubanza gushushanywa, kugirango igikoresho gishobora gushyirwaho ukurikije uburyo n'amahame bihuye, hamwe no gukoresha bisanzwe Birashobora kugenwa.
3.Kubera ko diameter yinyuma ya feri ya karubone ishobora kuba itandukanye, umwobo utari wo (hagati) hamwe nubunini bwa gaze iratandukanye, ibikoresho bitunganijwe ntibigomba guhinduka hamwe na feri ya karubone kuruhande, bityo bipima ubunini na ingano ya buri gice ni urufunguzo. Gutunganya no kwishyiriraho.
Icyuma cya karubonezikoreshwa cyane mubikorwa bya buri munsi, kandi kubikoresha ntabwo bitinda. Kubwibyo, kubungabunga buri gihe ibyuma bya karubone bigomba kugira amategeko abigenga kugirango ubuziranenge bwibikoresho bya karubone bishoboke kandi bitezimbere umuvuduko wakazi. Hano turasangira nawe imikorere ihamye yicyuma kitagira umwanda hamwe nicyuma cya karubone nibiki bigomba gukorwa:
1.Iyo ibyuma bya karubone bifunze, haracyari uburyo buciriritse busigaye mumubiri wa valve, kandi nabwo butwara igitutu cyagenwe. Mbere yo kuvugurura ibyuma bya karubone, funga valve ifunze imbere yicyuma cya karubone, fungura ibyuma bya karubone kugirango bivugururwe, kandi urekure burundu umuvuduko wimbere wumubiri wa valve. Mugihe amashanyarazi ya carbone flange cyangwa pneumatike yumupira, ingufu hamwe nikirere bigomba guhagarikwa mbere.
2.Muri rusange, icyuma cyoroshye cya karuboni icyuma gikoresha feri ikoresha tetrafluoroethylene (PTFE) nkibikoresho bifunga kashe, kandi hejuru yikimenyetso cyo gufunga umupira ukomeye wakozwe mubyuma. Niba ari ngombwa koza umuyonga wumupira, ugomba kwitonda kugirango wirinde kumeneka kubera kwangirika kwimpeta mugihe cyo gusenya.
3.Iyo gusenya ibyuma bya karubone, ibimera nimbuto kuri flange bigomba kubanza gukosorwa, hanyuma ibinyomoro byose bigomba gukomera gato kandi bigashyirwaho neza. Niba ibinyomoro kugiti cyabyo bikosowe neza mbere yizindi mbuto zishyirwaho, ubuso bwa gaze buzangirika cyangwa buvunike kubera gupakira kutaringaniye hagati yisura ya flange, bikavamo kumeneka hagati ya valve flange butt hamwe.
4.Niba valve isukuwe, umusemburo ukoreshwa ntushobora kuvuguruza ibice bigomba gusukurwa kandi ntibishobora kwangirika. Niba ari feri ya karubone ya gaze, irashobora gusukurwa na lisansi. Ibindi bice birashobora gusukurwa namazi yagaruwe. Mugihe cyo gukora isuku, ivumbi risigaye, amavuta nibindi byongeweho bigomba gusukurwa rwose. Niba bidashobora guhanagurwa namazi meza, birashobora gusukurwa ninzoga nibindi bikoresho byogusukura bitangiza umubiri wa valve nibice. Nyuma yo gukora isuku, tegereza umukozi ushinzwe isuku guhindagurika mbere yo guterana.
5.Niba imyanda mike iboneka mugupakira mugihe cyo kuyikoresha, imbuto ya valve irashobora gukomera gato kugeza igihe imyanda ihagaze. Ntukomeze gukomera.
6. Mbere yo gukoresha, umuyoboro nigice cyuzuye cyumubiri wa valve kigomba guhanagurwa namazi kugirango hirindwe ibyuma bisigaye hamwe nizindi izuba ryinjira mumyanya yimbere yumubiri wa valve.
Byongeye kandi, niba icyuma cya karubone gishyizwe hanze igihe kinini, kandi nta ngamba zo gutinya amazi, bizatera kwangirika kwimibiri ya valve nibigize. Muri ubu buryo, birakenewe kugerageza ituze rya feri ya karubone mugihe ikoreshwa.
