Xa iinjineli zicacisa iinxalenye zentsimbi okanye iintsimbi ezingwevu kwiinkqubo zamanzi, izixhobo ze-oyile, okanye iimpompo ezisebenza nzima, azifuni nje ukuphoswa—ziyafuna. uzinzo lwe-dimensional phantsi kwe-300+ yoxinzelelo lwebar, Ukuhambelana kwe-microstructure kwiibhetshi zeeqhekeza ezingama-500, kwaye ukunyamezela iqanda lokucutheka kwe-porosity kwiiflange ezithwele umthwalo. Yiyo loo nto ukukhangela kwinyani umzi mveliso wentsimbi-hayi i-arhente yokurhweba okanye isiseko jikelele-ayinakuxoxisana. Siye sabona iiprojekthi ezininzi zilibazisekile ngokubala kwamaqhuqhuva egraphite ngokungahambelaniyo, ubulukhuni beBrinell obungahambelaniyo (HBW 180–220 vs. obufunekayo 210–240), okanye iziphene ezingaphezulu ezinyanzelise ukwenziwa ngokutsha emva komatshini. Iqabane elifanelekileyo liphatha isinyithi njengesiyalo-kungekhona emva kokucinga.
Kutheni Ingqibelelo yezinto eziphathekayo iqala ixesha elide ngaphambi kokugalelwa
Uninzi lweentsilelo zibuyela emva kulawulo lwempahla ekrwada-hayi ubuchule bokuphosa. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ibhetshi nganye ye-EN-GJS-400-15 intsimbi ye-ductile iqala ngentsimbi yehagu eqinisekisiweyo kunye ne-ferrosilicon evela kwi-ISO 9001-eziqinisekisiweyo zokunyibilikisa izinyibilikisi. Baqinisekisa i-carbon equivalent (CE) ekufikeni kusetyenziswa uhlalutyo lokutsha kwe-LECO-kungekhona nje ii-certs zomthengisi. Silinganise ukukhukuliseka kwe-CE ukuya kuthi ga kwi-± 0.15% kumaqashiso angaqinisekiswanga, kubangele ngokuthe ngqo ilahleko ye-nodularity kwizindlu ezishinyeneyo. Ilebhu yabo iqhuba uqinisekiso lwe-ASTM A536 kubo bonke ubushushu: amandla aqinile, ubude, kunye nobulukhuni-zonke zifakwe nge-ID yesithando somlilo, ixesha lokugalela, kunye nesantya sokupholisa. Akukho "isampulu emele" izithuba. Oku akusiyo i-overkill-yindlela ababamba ngayo izindlu zesilinda kwiimpompo zepiston ukuya ku-± 0.02 mm ukujikeleza emva konyango lobushushu.
Apho iSand Casting idibana noLuleko lweCNC
Amalungu entsimbi angwevu njengesiseko sempompo okanye imizimba yevalvu ifuna ukucaba okuqinileyo (<0.05 mm ngaphezu kwe-600 mm) kunye namabhore angoomatshini achanekileyo. Nangona kunjalo ukuphosa isanti kukodwa akukwazi ukuyihambisa. I-QINGDAO QIANGSENYUAN ivala i-gap kunye nolawulo lwenkqubo edibeneyo ethe nkqo: isiseko sabo sisebenzisa i-resin-bonded sand molds kunye ne-real-time monitoring yokufuma, emva koko idlulisela i-castings ngokuthe ngqo kwiiseli ze-CNC ze-5-axis zangaphakathi. Akukho handoffs zangaphandle. Akukho kurhubuluza okulinganayo phakathi kokusakha kunye nokugqiba machining. Basebenza ngomatshini iindawo zokutywina ezibalulekileyo ngelixa ukuphosa kusekho uxinzelelo-ukusika ukuphazamiseka kwe-thermal nge-40% ngokubhekiselele kwi-post-annealing machining. Kwiivalvu zoxinzelelo ezifuna i-AMS 2700 Class 2 passivation, zidibanisa i-shot peening kunye ne-nitric acid yokucoca ngaphambi kokuhlolwa kokugqibela. Ayisiyiyo "ukuphosa + ukwenziwa komatshini." Lulandelelwano lobunjineli olunye.
Ukuqinisekiswa kwehlabathi lokwenyani: Yintoni abaVavanyayo ngokwenene
Abathengi be-oilfield yaseNyakatho yaseMelika abamkeli iingxelo zokuvavanya-ziqinisekisa ngokusebenzayo. Omnye umxhasi uvavanye iirola ezili-12 ze-winch centre shaft ngaphantsi kwe-120,000-umthwalo wokudinwa komjikelo kwi-20°C. Kwadlula konke. Enye i-cobalt-alloy nozzles yagijima (i-AMS 5387) ngokuchasene ne-slurry e-abrasive kwiiyure ze-72-i-zero erosion ngaphaya kwe-0.03 mm ubunzulu. Ezi ayizozinto zaselebhu. Ziyizinto zokuvelisa ezithunyelwa ngokulandelelana okupheleleyo: inombolo yobushushu, ukuprintwa kohlalutyo lweekhemikhali, ingxelo ye-CMM yazo zonke iifowuni ze-GD & T, kunye ne-micrograph ebonisa i-graphite morphology nge-ISO 945-1. Xa impompo ye-OEM yaseYurophu ifuna i-ISO 13003-ihambelana nedatha yokuqina kwe-fracture ye-EN-GJL-250 yentsimbi engwevu, bahambisa ixabiso lempembelelo ye-Charpy V-notch-hayi nje i-tensile specs. Yiloo ndlela uphepha ngayo "ibonakala ilungile kumzobo" imimangaliso.
Ukukhetha iFactory Yakho yentsimbi: Iitshekhi ezintathu ezingaxoxiswana
- Buza iirekhodi zabo zebhetshi ezintathu zokugqibela-hayi izatifikethi. Qinisekisa ukuba ukuqina, amandla okuqina, kunye nokwakheka kweekhemikhali zirekhodwa ngobushushu, hayi ngeqashiso ngalinye.
- Funa ubungqina bokusetyenziswa kwe-CMM kwinkqubo—kungekhona nje uhlolo lokugqibela. Imilinganiselo ebalulekileyo kufuneka ihlolwe emva komatshini olukhuni nangaphambi kokuba kugqitywe ukusika.
- Qinisekisa ukuba ngabanini bempahla yokusa kunye neyomatshini. Iinkqubo eziphuma ngaphandle zongeza iintsuku ezi-7 ukuya kwezi-12 kwaye zazisa iimpazamo zokulungelelanisa akukho nqaku le-GD&T linokulungisa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. idibana bobathathu. Indawo yabo e-Qingdao isebenza phantsi kwe-ISO 9001: 2015 kwaye igcina iinkqubo ezibhaliweyo kwisinyathelo ngasinye-ukusuka ekulungiseleleni isanti ukuya kwipakethe yokugqibela. Bathumela ngenqanawa ukuya kuMntla Merika, eYurophu, nakuMzantsi-mpuma we-Asia kunye namaxwebhu apheleleyo amasiko kunye nokuthotyelwa kwe-RoHS/REACH eyakhelwe kwizinto ezibonakalayo. Ukuba indlu yakho elandelayo yentsimbi yentsimbi kufuneka iphile iminyaka engama-20 kwi-actuator yevalve ye-subsea-okanye isiseko sakho sempompo yentsimbi engwevu kufuneka ithobe ukungcangcazela kwi-3,600 RPM-qala nge-metallurgical rigor, hayi amabango okuthengisa. Elona linamandla umzi mveliso wentsimbi ayithembisi imfezeko. Ingqina ukungqinelana—ubushushu obunye, ukubunjwa okunye, umlinganiselo omnye ngexesha.
