1. Kuvwuntauzya kwabupange
(1) Eezivalve ya butterflyilijisi bupange buli mbuli kkekke, mulyango wamukati uliswaanganizyigwa akugwasyilizyigwa azibeela zili 8 ziyumya, mpako yakujulu Φ620 ilaambuula amulyango wamukati, mpawo zyoonse zyakasyeedevvalavuilijalilidwe, mukati kamusenga nkuyumu kubambulula mpawo nchuubauba kuchincha. Zyoonse zyobile, kugwisya muya akusalazya mpako yamukati ziletela buyumuyumu bupati, mbuli mbokutondezyedwe achifanikisyo 1.
Bulamfu bwabwaanda bwazisamu bulaandeene, bupati bwabwaanda bulasika ku 380mm, mpawo bupati bwabwaanda busyoonto buli buyo a 36mm. Eelyo bulo nobwayumizigwa, kusiyana kwakupya nkupati, mpawo kucheya kutali kabotu kulakonzya kuleta tumpenda twakucheya, eezyo ziyoopa kuti maanzi azwe mumusunko wamaanzi.
2. Kubamba nzila:
(1) Busena bwakwaandaanya buli muchifanikisyo 1. Kobikka mamanino aamabbanga aabbokesi lyaatala, kopanga musenga woonse mukati, mpawo ulamfwu mutwe wamusenga munzila yeelede kuchitila kuti kube kujatilila kwamusenga akweenda kwamusenga aawo bbokesi nolisandululwa. Kakwiina kuzungaana, bulamfwu bwamutwe wa cantilever wa mabbanga obile aataboneki kumbali bulamfu kwiinda bulamfwu bwa mpako, aboobo akati ka nguzu zya musenga woonse uliimpene kulubazu lwa mutwe wa musenga kuchitila kuti musenga ukkalikene.
Nzila yakutila iijalikide yakabelesegwa, ∑F mukati: ∑F mumbali: ∑F kululama=1:1.5:1.3, sprue ibelesya ntambo yabulongo iijisi bupati bwamukati bwa Φ120, mpawo zibeela zyobile zya 200×100×40mm zitina zitapya zilabikkwa munsi kuchitila kuti butale butabi bulongo bwamusenga, 150×150×40 foam ceramic filter yakabikkwa munsi lya runner, mpawo 12 ceramic tubes zili abwamba bwamukati bwa Φ30 zyakabelesegwa kuti runner yamukati ijatane kabotu-kabotu munsi lya casting kwiinda mutanki lyakuyobweda maanzi munsi lya filter kuti lipange bottom pouring sheme mbuli mbokutondezyedwe muchifanikisyo 2
(3) Bika 14 ∮20 zibulo zyamuya mumulyango wakujulu, bikka Φ200 ntalisyo yamusenga akati kamutwe wamutwe, bikka butale butontola muzibeela zilemu azipati kuchitila kuti kube kuyuma kweendelana, mpawo ubelesye nzila yakuyungizya graphitization kuti uleke. Bupati bwabbokesi lyamusenga mbu 3600×3600×1000/600mm, mpo lyakaswaanganizyigwa a 25mm yabutale bupati kuchitila kuti kube manguzu akuyuma, mbuli mbokutondezyedwe achifanikisyo 3.
3. Kweendelezya nzila
(1) Kubamba: Kakutanaba kupanga, kobelesya Φ50×50mm musamu uulemekwa kuti usunke nguzu zyakusinkilila zyamusenga wa resin ≥ 3.5MPa, mpawo ujatisye butale butontola antoomwe achikwabilizyo kuchitila kuti bulongo bwamusenga bulaanguzu zyakukonzya kugwisya graphite iizwa aawo butale buteteete nobuyuma, akulesya butale kuti butanyonyooki chibeela chakuchijaana kwachiindi chilamfu kuti chichite kusanzya kwamusenga.
Kupanga nsinga: Nsinga yamusenga ilaandaanizyigwa muzibeela zili 8 zyeelene azibeela zili 8 ziyumya, eezyo zijatikizyidwe kwiinda mumulyango waakati. Taakwe zibeela zimbi zigwasilizya akugwisya muya kunze lyamutwe waakati-kati. Kuti musenga taukonzyi kubambululwa mpawo wazwa muya, musenga ulakonzya kuzwa antoomwe amabbanga aamuwo ziyooboneka musule akutilwa. Akaambo kakuti busena boonse bwamusenga mbupati, bwaandaanizyigwa muzibeela zili musanu aatatu. Kweelede kuba anguzu zizulide akuyuma kuchitila kuti musenga utanyonyooki nikwakazwa buumba, mpawo utanyonyooki nikwakatilwa. Kusanduka kulachitika, kuchitila kuti kube bupati bwabwaanda bweelene. nkaambo kaako, twakapanga chifuwa chaalubazu, mpawo twakachianga achifwuwa chamukati antambo yakunjizya muuya kuti tugwisye muya uuzwa kumutwe wamukati kuchitila kuti bulongo bwamusenga bube buyumu aawo notupanga chifuwa. Mbuli mbokutondezyedwe achifanikisyo 4.
(4) Bbokesi lyakujala: Katulanga kuti nkuyumu kusalazya musenga mukati ka bbokesi lya butterfly valve, musenga woonse ulapentwa amapeni obile, musenga wakusaanguna ulapentwa a zirconium penti (Baume degree 45-55), mpawo musenga wakusaanguna ulapentwa akutentwa. Musule akuyuma, penta bbazu lyabili apenti ya magnesium iijisi bukoko (Baume degree 35-45) kuchitila kutabilila kuti penti itanamati kumusenga akupya, eeyo iitakonzyi kusalazyigwa. Cibeela cha mutwe wamukati chilengelezyegwa a Φ200 payipi yabutale bwa chifuwa chamukati a zikulukulu zyotatwe zya M25, zyakabambwa akujalwa a bbokesi lya musenga lyakujulu lijisi zivwunisyo zya zikulukulu mpawo zilalangwa kuti naa bupati bwabwaanda bwachibeela chimwi achimwi bulikozyenye.
4. Nzila yakunyengulula akutila
(1) Belesya Benxi low-P, S, Ti high-quality Q14/16# pig iron, mpawo uyibike achiimo cha 40%~60%; zintu zilimbuli P, S, Ti, Cr, Pb, azimwi zilalanganizigwa loko muzibulo zyakasweeka, mpo kunyina nsimbi amafuta zizumizigwa, mweelwe wakuyungizya uli 25%~40%; chaja yakajokezyegwa yeelede kusalazyigwa a shot blasting kaitanabelesegwa kuchitila kuti chaja isalala.
(2) Bweendelezi bwazibeela zipati musule lyamulilo: C: 3.5-3.65%, Si: 2.2%-2.45%, Mn: 0.25%-0.35%, P≤0.05%, S: ≤0.01%, Mg (zisyaala): 0.035% ~0.05%, munsi lyachikobela, chivwumbyo, munsi lyabbwe lyakukwabilila, bbola lyamukati, bbola lyamukati, bbola lyamukati, bbola lyamukati. mweelwe waansi wa Mg (uusyeede) weelede kutolwa mbuli mbukonzeka.
(3) Busilisi bwakusanzya: low-magnesium antoomwe a low-rare-earth spheroidizers zilabelesyegwa, mpawo mweelwe wakuyungizya ngu 1.0%~1.2%. Nzila yabuzubaa buzuba yakusanzya, 0.15% ya inoculation yachiindi chomwe ilavwumbidwe a nodulizer munsi aachibbeeke, mpawo spheroidization yamana. I slag mpawo ilapegwa mulimo wabili wa 0.35%, mpawo 0.15% ya 0.15% ilachitwa muchiindi chakutila.
(5) Nzila yakutila chakufwambaana yakabelesegwa, kupya kwakutila kuli 1320°C~1340°C, mpawo chiindi chakutila 70~80s. Butale buteteete tabukonzyi kunyonganizyigwa muchiindi chakutila, mpawo nkomeki ya sprue lyoonse ilizwide kuchitila kutabilila kuti muya azintu zibikkilizyidwe zitanjili mubulongo kwiinda muchibelesyo. mpako.
5. Zyakazwa mumusunko wakusowa
(1) Amusunke nguzu zyakukwela zya bbuloki lyakusunka: 485MPa, kulampa: 15%, kuyuma kwa Brinell HB187.
(2) Mweelwe wa spheroidization ngu 95%, bupati bwa graphite mbu grade 6, mpawo pearlite mbu 35%. Bupange bwa metallographic buli muchifanikisyo 5.
(3) Taakwe tumpenda twakajanika mu UT antoomwe a MT mukujana tumpenda twabili twazibeela ziyandikana.
(4) Kuboneka kulipapalete alimwi nkuteteete (Langa mufanikisyo 6), kakunyina tumpenda twakusofwaazya mbuli musenga, bulongo, zijazyo zyakutontola, azimwi, bupati bwabwaanda bulikozyenye, mpawo bupati bulazuzikizya ziyandikana muzifwanikiso.
(6) 20kg/cm2 hydraulic pressure test nikwakamana kubelesegwa tiikwakatondezya kuvwundauka pe
6. Mamanino
Kweelana abupange bwa vvalavu eeyi, penzi lyakutazungaana akufwambaana kwakusanduka kwamusenga mupati akati-kati alimwi akukatazya kusalazya musenga kulamanizyigwa kwiinda mukukankaizya nzila yakubamba nzila, kupanga akubambulula musenga akubelesya zintu zijisi zirconium. Kubamba mabbanga aakunjilila muya kulatantamuka mapopwe muzintu zyakusowela. Kuzwa kubweendelezi bwakubelesya bbibi lyamulilo anzila yakubelesya, kkeyala yakusefa yabulongo antoomwe anzila yakubamba zintu zyabulongo zilabelesyegwa kusinizya kusalala kwabutale buteteete. Musule aakusilikwa ziindi zyiingi, bupange bwazibulo zyamabwe azimwi. Ikubeleka koonse kwasika aawo mpobayanda basikuula
