Xa iinjineli zichaza I-316 okanye i-316L yensimbi engenasici kumacandelo abalulekileyo-i-valve zoxinzelelo kwiinkqubo ze-hydraulic offshore, izindlu ze-cylinder kwiimpompo zepiston ezinoxinzelelo oluphezulu, okanye i-winch center shaft rollers kwiimoto zobunjineli-ayikukhetha nje izinto eziphathekayo. Bakhetha isiqinisekiso sokusebenza: ukuchasana ne-chloride-induced pitting, ukuzinza kwesakhiwo kumaqondo okushisa aphakamileyo, kunye nokunyaniseka kwexesha elide kwiindawo ezinobundlobongela. Kodwa eso siqinisekiso sibambe kuphela ukuba umzi-mveliso uhambisa inxalenye yezinto ezintathu: ukungaguquguquki kwesinyithi, ukuthembeka komda phantsi kolawulo oluqinileyo lwe-GD&T, kunye nokunyamezelana kwenkqubo yokukhukuliseka kwiibhetshi.
Yiyo loo nto ukukhangela kwinyani 316 316L umzi-mveliso wentsimbi engenasici izinto-kungekhona umthengisi wesinyithi jikelele, kungekhona inkampani yokurhweba yokugubungela njengomvelisi, kodwa isibonelelo apho yonke i-316L yokushisa ilandelelwa kwiingxelo zovavanyo oluqinisekisiweyo lwe-mill, apho i-CNC i-parameters ye-machining ihlaziywa ngokukodwa kwiimpawu zokuhamba kwe-austenitic stainless, kwaye apho i-porosity yokuphosa ibanjwe ngaphambi konyango lokugqibela lokushisa-kungekhona emva.
Siye sabona iiprojekthi ezininzi zilibazisekile ngenxa yokuba "umthengisi wensimbi engenasici" wamkele imizobo ngaphandle kokubonisa iflegi yokuba isiseko sempompo esinodonga olucekethekileyo lwe-316L siya kubetha ngexesha lokunciphisa uxinzelelo ngaphandle kokuba umatshini owenziwe ngokulandelelana kunye namandla abambezelayo alawulwayo. Siye savavanya imilomo ye-AMS 5387 ye-cobalt alloy ecaleni-ne-ecaleni kunye ne-316L elinganayo kumjikelo wokulingisa wenaliti yamanzi olwandle-kwaye sabukela ukubanjwa kwe-stainless apho ezinye iindlela ezinexabiso eliphantsi zisilele kwiiyure ezingama-2,800. Ayilolwazi lwethiyori olo. Yakhelwe kwisixhobo sethu, iiprothokholi zethu zokuhlola, kunye nendlela esilinganisa ngayo yonke i-CMM probe ngaphambi kokulinganisa umphezulu wesitulo sevalve engama-316L.
E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ukuchaneka akubekwanga phezu kwemveliso-yenzelwe kuyo. Indawo yethu ehambelana ne-ISO eQingdao iphatha zombini i-investment-cast kunye ne-sand-cast 316 / 316L iinxalenye zentsimbi engenasici, emva koko iwagqibe nge-multi-axis CNC machining egcina ukunyamezela kwe-± 0.01 mm kwiimpawu ezifana nokutywinwa komphezulu kunye neepateni ze-bolt-hole. Asilukhupheli ngaphandle unyango lobushushu. Asizamkeli iibhilidi ezingaqinisekiswanga. Yonke impahla ekrwada yenziwa uhlalutyo lwe-spectrographic ekufikeni kwayo-kwaye ibhetshi epheleleyo yokulandeleka ifakwe kwinkqubo yethu ye-ERP ukuya kwinombolo yeziko kunye nesantya sokupholisa.
- Ulawulo lwezinto eziphathekayo luqala ngaphambi kokusika: Sifumana i-316L ukusuka kwii-mills eziqinisekisiweyo kwi-ASTM A240 / A484, kunye nomxholo we-Mo obanjwe phakathi kwe-2.0-3.0% kunye ne-carbon ≤0.03%-iqinisekisiwe ngokushisa, kungekhona ngokuthumela.
- Umatshini uthintela ukuqina komsebenzi: Sisebenzisa i-RPM ephantsi, izicwangciso eziphezulu zokutya kunye nezixhobo ze-carbide ezifakwe kwi-PVD ezenzelwe i-austenitic stainless, ukunciphisa ukushisa kobushushu kunye nokugcina ukuxhathisa kwe-corrosion kwi-surface layer.
- Umphezulu wemfezeko awuxoxiswana: Kwizindlu zempompo ezivezwe kwi-brine, sisebenzisa i-passivation nge-ASTM A967 (Indlela B) kwaye siqinisekise umlinganiselo we-Cr / Fe kunye ne-XRF-akukho kuhlolwa okubonakalayo kuphela.
- Ukuqinisekiswa kwe-Dimensional kwenzeka kathathu: pre-machining (ukuqinisekiswa kwe-stock), i-mid-process (ii-datums ezibalulekileyo), kunye nokugqiba (i-CMM epheleleyo yokuskena imodeli ye-CAD).
Abanye banokuphikisa ukuba nayiphi na i-ISO-certified foundry inokuvelisa i-316L castings. Kodwa ukuphosa i-316L akufani nokuphosa intsimbi engwevu. I-nickel yayo ephezulu kunye nomxholo we-molybdenum wonyusa umngcipheko wokukrazula. I-thermal conductivity ephantsi ifuna ulawulo oluchanekileyo lokungunda kwangaphambili. Kwaye ukuthambekela kwayo ukwenza isigaba se-sigma ngexesha lokupholisa okucothayo kuthetha ukuba iishedyuli zonyango lobushushu kufuneka ziqinisekiswe-zingacingelwa. Siye salahla ubushushu obubini beprototype kuba amazinga okupholisa awela ngaphandle kwe-5 ° C/min yefestile efunekayo ukunqanda ukugquma. Leyo yindleko yokutsiba uqeqesho lwe-metallurgical.
Amandla ethu alele ekudityanisweni okuthe nkqo: ukuphosa, umatshini, unyango lobushushu, kunye nokugqiba kwenzeka phantsi kophahla olunye, kunye nemigangatho ekwabelwana ngayo ye-metrology kunye ne-real-time feedback loops phakathi kwamasebe. Xa umthengi ethumela umzobo womzimba wevalve yoxinzelelo lwe-316L ongeyomgangatho onamatshaneli okupholisa asymmetric, iqela lethu alicaphuli nje ixabiso kunye nexesha lokukhokela. Siqhuba ukulinganisa ukuqinisa, ukucebisa i-geometry tweaks encinci yokunciphisa i-shrinkage cavities, kwaye sicebise ulandelelwano lwe-machining olunciphisa ukubethelwa kwakhona-ukusika ixesha lomjikelo nge-22% ngaphandle kokuncama i-flatness.
Abathengi behlabathi-ukusuka kwii-OEMs ze-hydraulic eJamani ukuya kubaboneleli benkonzo ye-oilfield e-Texas-bathembele kuthi kuba ukuthembeka akulobango lokuthengisa apha. Inokulinganiswa: I-99.4% yokuhanjiswa kwexesha kwiinyanga ze-18 ezidlulileyo, ukusilela kwintsimi ye-zero ebotshelelwe ekungahambelani kwezinto eziphathekayo, kunye nokulungela uphicotho olupheleleyo lwe-ASME BPVC iCandelo II okanye i-PED 2014/68/EU yokuthobela amaxwebhu. Sithumela i-316 kunye ne-316L i-stainless steel components ukuya eNyakatho Melika, iYurophu, kunye ne-Asia-mpuma ye-Asia-kungekhona njengempahla, kodwa njengoko kubhaliweyo, ukulandelwa, iindawo eziqinisekisiweyo ezisebenzayo.
Ukuba ufuna i 316 316L umzi-mveliso wentsimbi engenasici ephatha icandelo lakho njenge-hardware ebaluleke kakhulu yobuthunywa-hayi i-SKU yorhwebo-ufuna amaqabane asebenze amakhulu ezindlu ze-316L ze-cylinder zeempompo zodaka ezithathu, abasiqondayo isizathu sokuba i-angle yedrafti ye-0.5 ° ibaluleke ngaphezu koburhabaxa bomphezulu kwisihlalo sevalve yamanzi olwandle, kwaye abagcina imathiriyeli ekrwada ibonakaliswe ecaleni kwayo yonke i-certs egciniweyo. Asiyondlela eqhelekileyo leyo. Luhambo lwethu lwemihla ngemihla.
Jonga phambili: sandisa amandla ethu kwiinkqubo zokwenziwa kwe-hybrid casting-machining kwiindibano ezinkulu ezinobubanzi obuyi-316L kwaye sigxininise i-R&D kwisisombululo esiphantsi sobushushu obuphantsi ukuze kuphuculwe ukuxhathisa umhlwa kwe-intergranular. Ngenxa yokuba kwizicelo eziphezulu zoshishino, inxalenye efanelekileyo yensimbi engenasici ayenziwa nje. Ifunyenwe-ibhetshi ngebhetshi, ubushushu ngobushushu, umlinganiselo ngomlinganiselo.
