1. Isesengura ry'imiterere
(1) Ibivalve y'ikinyugunyuguifite imiterere isa n'uruziga, umwobo w'imbere uhujwe kandi ushyigikiwe n'imbavu 8 zikomeza, umwobo wo hejuru wa Φ620 uhuza n'umwobo w'imbere, n'ibindi bicevalveifunze, igice cy'umucanga kiragoye gusana kandi byoroshye kwangirika. Ibyuka bisohora umwuka ndetse no gusukura icyumba cy'imbere bitera ingorane nyinshi, nk'uko bigaragara ku Ishusho ya 1.
Ubunini bw'urukuta rw'ibice bicukurwamo ibyuma buratandukanye cyane, ubunini ntarengwa bw'urukuta bugera kuri mm 380, naho ubunini ntarengwa bw'urukuta ni mm 36 gusa. Iyo ibice bicukurwamo ibyuma bikomera, itandukaniro ry'ubushyuhe riba rinini, kandi ukugabanuka kutaringaniye bishobora gutuma habaho kugabanuka kw'ibice n'imyenge y'ibice bicukurwamo ibyuma, ibyo bigatuma amazi asohoka mu igeragezwa rya hydraulic.
2. Igishushanyo mbonera cy'ibikorwa:
(1) Ubuso butandukanya bugaragara ku Ishusho ya 1. Shyira impera irimo imyobo ku gasanduku ko hejuru, kora igice cy'umucanga cyose mu mwobo wo hagati, kandi gura umutwe w'ibanze neza kugira ngo woroshye gufata igice cy'umucanga no kugenda k'igice cy'umucanga iyo agasanduku kazungurutse. Ihamye, uburebure bw'umutwe w'inkingi y'imyobo ibiri idasobanutse ku ruhande ni burebure kuruta uburebure bw'umwobo, ku buryo hagati y'uburemere bw'igice cy'umucanga cyose haba hateganye n'uruhande rw'umutwe w'ibanze kugira ngo urebe ko igice cy'umucanga gihamye kandi gihamye.
Hashyizweho uburyo bwo gusuka bufunze neza, ∑F imbere: ∑F itambitse: ∑F igororotse = 1:1.5:1.3, umuyoboro ukoresha umuyoboro wa ceramic ufite umurambararo w'imbere wa Φ120, kandi ibice bibiri by'amatafari ya 200×100×40mm arefractory bishyirwa hasi kugira ngo hirindwe ko icyuma gishongeshejwe kitavamo neza. Ku bijyanye n'ibumba ry'umucanga, hashyizweho akayunguruzo ka ceramic ka 150×150×40 munsi y'akayunguruzo, kandi imiyoboro 12 ya ceramic ifite umurambararo w'imbere wa Φ30 ikoreshwa kugira ngo akayunguruzo k'imbere gahuzwe neza no hepfo y'aho amazi aturuka anyura mu kayunguruzo kugira ngo habeho uburyo bwo gusuka hasi, nk'uko bigaragara ku Ishusho ya 2 Essence
(3) Shyira imyobo 14 ∮20 y'umwuka mu ibumba ryo hejuru, shyiramo umwobo w'umucanga wa Φ200 hagati y'umutwe w'imbere, shyiramo icyuma gikonje mu bice binini n'ibinini kugira ngo urebe ko icupa rikomera neza, kandi ukoreshe ihame ryo kwagura graphitization kugira ngo uhagarike. Ingufu zo kugaburira zikoreshwa mu kunoza umusaruro w'ibikorwa. Ingano y'agasanduku k'umucanga ni 3600 × 3600 × 1000 / 600 mm, kandi gakozweho icyuma gifite ubugari bwa 25 mm kugira ngo gikomere bihagije kandi gikomere, nk'uko bigaragara ku Ishusho ya 3.
3. Kugenzura ibikorwa
(1) Gushushanya: Mbere yo gushushanya, koresha icyitegererezo gisanzwe cya Φ50×50mm kugira ngo upime imbaraga zo gukanda kw'umucanga wa resin ≥ 3.5MPa, hanyuma ukaze icyuma gikonje n'icyuma gifata kugira ngo urebe neza ko ifu y'umucanga ifite imbaraga zihagije zo guhangana na grafiti ikorwa iyo icyuma gishongeshejwe gikomera. Ibikoresho bya shimi byagutse, kandi wirinde ko icyuma gishongeshejwe kigira ingaruka ku gice gifata kugira ngo gikoreshwe igihe kirekire.
Gukora urufatiro rw'umucanga: Urufatiro rw'umucanga rugabanyijemo ibice 8 bingana n'imbavu 8 zo gushimangira, zihujwe binyuze mu mwobo wo hagati. Nta kindi gice cy'inkunga n'ibice bisohora umwuka uretse umutwe wo hagati. Niba urufatiro rw'umucanga rudashobora gukosorwa kandi ibyuka bivamo umwuka, icyuho cy'umucanga n'imyobo y'umwuka bizagaragara nyuma yo gusukwa. Kubera ko ubuso bwose bw'uruziga rw'umucanga ari bunini, rugabanyijemo ibice umunani. Rugomba kuba rufite imbaraga zihagije n'ubudahangarwa kugira ngo urufatiro rw'umucanga rutazangirika nyuma yo gusohora ibishishwa, kandi ntiruzangirike nyuma yo gusukwa. Habaho guhindagurika, kugira ngo harebwe ko ubugari bw'urukuta rw'icyuma gishongeshwa bungana. Kubera iyo mpamvu, twakoze by'umwihariko igufwa ryihariye ry'uruziga, maze turihambira ku igufwa ry'uruziga n'umugozi wo guhumeka kugira ngo dukure imyuka isohora umwuka mu mutwe kugira ngo turebe ko ibishishwa by'umucanga bifatanye neza mu gihe cyo gukora urufatiro rw'umucanga. Nk'uko bigaragara ku Ishusho ya 4.
(4) Agasanduku ko gufunga: Bitewe nuko bigoye gusukura umucanga uri mu mwobo w'imbere w'ikinyugunyugu, igice cyose cy'umucanga gisizwe irangi ry'ibice bibiri, igice cya mbere gisizwe irangi rya zirconium rishingiye kuri alcool (Baume degree 45-55), hanyuma igice cya mbere gisizwe irangi hanyuma kigatwikwa. Nyuma yo kumisha, siga irangi rya magnesium rishingiye kuri alcool (Baume degree 35-45) ku rwego rwa kabiri kugira ngo hirindwe ko irangi rifata ku mucanga no gutwika, ridashobora gusukurwa. Igice cy'umutwe w'imbere gimanikwa ku muyoboro w'icyuma wa Φ200 w'inyubako nyamukuru y'igufwa ry'ibanze ukoresheje vis eshatu za M25, bikomezwa kandi bifunze hakoreshejwe agasanduku k'umucanga ko hejuru gafite imipfundikizo ya vis kandi harebwa niba ubugari bw'urukuta rwa buri gice bungana.
4. Uburyo bwo gushonga no gusuka
(1) Koresha icyuma cy'ingurube cya Benxi low-P, S, Ti Q14/16# cyiza cyane, hanyuma ugishyire ku kigero cya 40% ~ 60%; ibintu bike nka P, S, Ti, Cr, Pb, nibindi bigenzurwa cyane mu byuma bishaje, kandi nta ngese n'amavuta byemewe, igipimo cyo kongeramo ni 25% ~ 40%; umuriro usubijwe ugomba gusukurwa no guturitsa amasasu mbere yo gukoresha kugira ngo umuriro ugire isuku.
(2) Igenzura ry'ibice by'ingenzi nyuma y'itanura: C: 3.5-3.65%, Si: 2.2%-2.45%, Mn: 0.25%-0.35%, P≤0.05%, S: ≤0.01%, Mg (ibisigaye): 0.035% ~0.05%, hashingiwe ku kwemeza ko spheroidization ihinduka, hagomba gufatwa Mg (ibisigaye) ku rugero rushoboka.
(3) Uburyo bwo gutera umuti wa Spheroidization: hakoreshwa spheroidizers zifite magnesium nkeya n'izidafite ibara ryinshi, kandi igipimo cyo kongeramo ni 1.0% ~ 1.2%. Uburyo busanzwe bwo gutera umuti wa Spheroidization, 0.15% by'uburyo bwo gutera umuti rimwe gusa bitwikirwa kuri nodulizer iri hepfo y'ipaki, hanyuma spheroidization irarangira. Hanyuma slag igabanywa kugira ngo habeho gutera umuti wa kabiri wa 0.35%, hanyuma hagakorwa gutera umuti wa 0.15% mu gihe cyo gusukura.
(5) Uburyo bwo gusuka vuba mu bushyuhe buke burakoreshwa, ubushyuhe bwo gusuka ni 1320°C ~ 1340°C, naho igihe cyo gusuka ni 70~80s. Icyuma gishongeshejwe ntigishobora guhagarara mu gihe cyo gusuka, kandi igikombe cya sprue gihora cyuzuye kugira ngo hirindwe ko umwuka n'ibintu bivamo bishobora kwinjira mu ibumba binyura mu mwobo.
5. Ibisubizo by'ibizamini byo gukata
(1) Gerageza imbaraga zo gukurura z'agace k'igerageza: 485MPa, kurekura: 15%, ubukana bwa Brinell HB187.
(2) Igipimo cya spheroidization ni 95%, ingano ya grafiti ni urwego rwa 6, naho pearlite ni 35%. Imiterere ya metallographic igaragara ku Ishusho ya 5.
(3) Nta nenge zishobora kwandikwa zabonetse mu gupima udukosa twa kabiri twa UT na MT ku bice by'ingenzi.
(4) Ishusho irarambuye kandi iraryoshye (reba Ishusho ya 6), nta busembwa buvanze nk'imicanga, imitako y'ibitaka, imitako ikonje, nibindi, ubugari bw'urukuta burangana, kandi ingano zujuje ibisabwa ku bishushanyo.
(6) Ikizamini cy'umuvuduko wa hydraulic wa 20kg/cm2 nyuma yo gutunganya nta kintu cyagaragaye cyavuyemo
6. Umwanzuro
Dukurikije imiterere y'iyi valve y'ibinyugunyugu, ikibazo cyo guhinduka kw'umucanga munini hagati no gusukura umucanga bigoranye gikemurwa hibandwa ku gishushanyo mbonera cy'ibikorwa, gukora no gufunga umucanga no gukoresha irangi rishingiye kuri zirconium. Gushyiraho imyobo y'imyobo birinda ko habaho imyenge mu byuma bicukurwa. Kuva kuri sisitemu yo kugenzura umuriro w'itanura no gukoresha uburyo bwo gucukura, ikirahure cya foam ceramic na ikoranabuhanga rya ceramic ingate bikoreshwa kugira ngo icyuma gishongeshwe gisukurwe neza. Nyuma yo gutera imiti myinshi, imiterere ya metallographic y'ibyuma bicukurwamo n'imikorere itandukanye yageze ku bisabwa n'abakiriya.
