Xa iinjineli zicacisa i-ASTM A747 castings, ayikhethi nje into-bayazibophelela kumda wokusebenza. Lo mgangatho ulawula i-cobalt-chromium-nickel alloys eyenzelwe ukugqoka ngokugqithiseleyo, ukubola, kunye nokuxhatshazwa kwe-thermal-ingakumbi kwiindawo ezijikelezayo zempompo, imizimba ye-valve ephezulu, kunye nezindlu zenkqubo ye-hydraulic apho ukungaphumeleli kungeyona inketho. Kodwa ukufumana ukukhutshwa kwe-ASTM A747 akukho malunga nokufumana * nayiphi na into efumanekayo. Imalunga nokusebenzisana nomthengisi ophatha ukuhambelana kwe-metallurgical njengento engaxoxisiyo, eqinisekisa lonke ubushushu ngokuchasene ne-AMS 5387 imida yeekhemikhali, kwaye ngubani olawula umxokelelwane opheleleyo: ukusuka kwi-T800-grade ye-billet ekrwada yokulandelelwa ukuya kuhlolo lokugqibela lwe-GD&T kwi-CMM elungisiweyo.
Kutheni abakhangeli be-"ASTM A747" bahlala bebetha eziphelweni
Siye saphonononga ngaphezulu kwe-200 RFQs ezisuka kuMntla Merika wempompo ye-OEMs kunye nababoneleli benkonzo baseYurophu kwiinyanga ezili-18 ezidlulileyo. Uninzi luqala ngombuzo omnye ongxamisekileyo: "Ngaba ungayiphosa i-ASTM A747-kwaye uyingqine?" Uninzi lwababoneleli-mpahla luphendula ngokuthi “ewe” emva koko bazinze kwisiqinisekiso semathiriyeli. Bancibilika kwikontraka engaphantsi, batsibe uvavanyo lokutya kwe-intergranular ngokwe-ASTM A262 Practice E, okanye abanako ukunika iingxelo zespectrographic ezicacileyo. Siye sabona ukuphosa iibhetshi zaliwe-kungekhona ngenxa yempazamo ye-dimensional-kodwa ngenxa yokuba umxholo wechromium wehle nge-0.3% ngaphantsi koluhlu lwe-28-32% olufunwa yi-ASTM A747. Lo msantsa awubonakali kumzobo. Ibonakala njengokungena kwangaphambi kwexesha kwinkonzo yerhasi emuncu.
Ingxaki yokwenyani ayikukwazi ukuphosa. Kukudityaniswa ngokuthe nkqo. Ukuthotyelwa kwe-ASTM A747 yokwenyani kufuna ulawulo kwizigaba ezine ezidityanisiweyo: ukuthathwa kwemathiriyeli ekrwada eqinisekisiweyo, i-vacuum-arc enyibilikisiweyo (i-VAR) okanye ukugalelwa kwe-induction-melted, isisombululo se-annealing kunye nexesha elichanekileyo lokufunxa / ubushushu, kunye nokuqinisekiswa kwe-microstructure emva kokunyanga. Ngaphandle kolu lawulo, "i-ASTM A747 factory" iba lulwimi lokuthengisa-hayi imveliso yokwenene.
Apho ukuphosa okuchanekileyo kuhambelana nokuqinisekiswa okusebenzayo
E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., I-ASTM A747 ayiyonto yoluhlu lokukhangela. Sisiseko somsebenzi wethu wecandelo lempompo. Imigca yethu yokuphosa isanti igalela ukushisa phantsi kwe-argon shrouding. Yonke ibhetshi ihlalutya i-spectrographic ngaphambi kokuthululelwa-kwaye kwakhona emva konyango lobushushu. Sigcina ukulandeleka okugcweleyo: inani lokunyibilika, ijiko lobushushu leladle, izinga lokupholisa idatha, kunye nobunzima be-Rockwell C kwiindawo ezintathu zokusasa ngakunye. Kwiindawo ezihambelanayo ze-AMS 5387-ezifana ne-cobalt alloy nozzles kwiimpompo eziphindaphindayo-yongeza i-ASTM E112 yokuqinisekisa ubungakanani bengqolowa kunye ne-ASTM A262 Practice E intergranular corrosion test kwiisampuli zobungqina.
Olu qeqesho lubaluleke kakhulu kwiindawo ezinobuzaza bejometri. Thatha i-piston pump cylinder housings: ukuguquguquka kodonga olungaphezulu kwe-± 0.15 mm kubangela ukwanda okungalinganiyo kwe-thermal, okukhokelela ekubanjweni phantsi komthwalo. Inkqubo yethu idibanisa ukuchaneka kwepatheni yotyalo-mali kunye neebhokisi ezingundoqo ze-CNC-emva koko iqinisekisa i-bores ebalulekileyo kunye ne-air gaging kunye nokugqiba umphezulu ngeprofilometry. Isiphumo? Izindlu ze-cylinder zibambe <0.005 mm ukungqukuva ngaphaya kwe-300 mm ubude, nakwi-ASTM A747 esekwe kwi-T800.
Ezine non-negotiables kwi-mission-ezibalulekileyo ASTM A747 ubonelelo
- Ukuvela kwezinto ezikrwada: Sifumana kuphela iibhilithi ze-cobalt-nickel ezisulungekisiweyo ze-VAR ezineengxelo zovavanyo lokusila ezigubungela i-C, i-Cr, i-Ni, i-Mo, i-Fe, i-Si, i-Mn, kunye ne-N-iqinisekisiwe ngokuchasene ne-ASTM A747 Ukunyamezela kweTheyibhile 1 ngaphambi kokwamkelwa
- Amaxwebhu onyango lobushushu: Wonke umjikelo wesithando somlilo ufakiwe-ixesha lokufunxa, amazinga eendlela, indawo yombethe, kunye nokucima ubushushu obuphakathi-kunye neesignesha zedijithali ezilandelekayo kumqhubi kunye nokutshintsha
- Kwinkqubo ye-metrology: Imilinganiselo ebalulekileyo ilinganiswe phakathi kwenkqubo usebenzisa i-Zeiss CONTURA G2 CMMs; ingqibelelo yomphezulu iqinisekisiwe nge-SEM yomfanekiso kwisampulu yokusikwa
- Ulungelelwaniso lovavanyo olusebenzayo: Iindibano zokugqibela zivavanywa ngoxinzelelo nge-API 598 nganye, kunye namazinga okuvuza arekhodiweyo-hayi nje kudlula / kusilele-ngokuchasene nemida echaziweyo ngabathengi.
Oku akuyothiyori. Kwikota edlulileyo, sihambise iirola zeshaft ze-ASTM A747 eziziko le-42 ye-offshore winch systems. Iyunithi nganye iphethe ukulandelwa kobushushu obugcweleyo, amandla okuqina> 1000 MPa, kunye nokuqina kwempembelelo> 35 J kwi -20 ° C-konke kuqinisekisiwe nge-ASTM E23. Umxhasi unike ingxelo yokusilela ebaleni kwiinyanga ezili-18 zokusebenza kwindawo ezele ityuwa elwandle.
Ukufikelela ngokuthe ngqo, hayi izaleko zabasasazi
Iiprojekthi ze-ASTM A747 zifuna incoko yobunjineli—hayi iifomu zokuodola. Xa umyili wevalvu yehydraulic yaseJamani esicela ukuba siqinisekise ukuqukuqela kwendlela yejiyometri ehlaziyiweyo, iqela lethu lasebenzisa ulinganiso loxinzelelo lwe-thermal *phambi* kokusetyenziswa kwezixhobo, liphawule indawo enokubakho eshushu kwindawo ekudibanela kuyo izibuko ngentsimbi yesi-3, kwaye licebise uhlengahlengiso lwendawo ebandayo. Le ntsebenziswano yanciphisa ixesha labo lokukhokela ngeentsuku ezingama-22. Siphatha utoliko lwe-GD&T, ukuqinisekiswa komzobo, kunye nempendulo yokwenziwa-hayi njengezongezo, kodwa njengamanyathelo aqhelekileyo.
Indawo yethu eqinisekisiweyo ye-ISO 9001 eQingdao isebenza ngokuthe ngqo kwi-B2B kuphela. Akukho abasasazi. Akukho bantu baphakathi. Uthetha nenjineli ecwangcisa i-CNC lathe ukusika iplagi yakho ye-ASTM A747-hayi irep yokuthengisa ecaphula kwikhathalogu yePDF. Amaxesha okukhokela amisiwe ngexesha lekowuteshini: Iiveki ze-12 zokuvunywa kwenqaku lokuqala, iiveki ezisi-8 zokuphindaphinda imiyalelo-itshixiwe ngokubhaliweyo, kunye nezohlwayo zokulibaziseka.
Intsebenziswano yomzi-mveliso we-ASTM A747 iyaphumelela xa i-metallurgy, oomatshini, kunye nokuphendula kudibana. Ukuba umyalelo wakho wokuphosa olandelayo ufuna ingqibelelo ebhaliweyo ye-cobalt-alloy-hayi nje i-spec sheet-qala ngokulandelelwa kwezinto eziphathekayo, qinisekisa iirekhodi zonyango lokushisa, kwaye uqinisekise ukuba ngubani osayinayo kwingxelo yokugqibela ye-CMM. Umahluko phakathi kokuthotyelwa kweenkcukacha kunye nokuthembeka kwentsimi kuhlala kwezo nkcukacha. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha loo mahluko kuyo yonke into yokugalela.
