Imisebenzi yefektri yentsimbi engatyiwayo ifuna okungaphezulu nje kokunyibilika nokugalela. Bafuna ukuchaneka, uqeqesho lwe-metallurgical, kunye nolawulo lwenkqubo olusindayo kwimijikelezo yoxinzelelo oluphezulu lwe-hydraulic, i-abrasive oil-field environments, kunye namashumi eminyaka yokulayisha kwibhayisekile kwizithuthi zobunjineli. Xa i-valve ye-valve ye-pressure yezindlu i-3,000 psi-okanye i-cobalt-alloy pump nozzle iyancipha emva kweeyure zokusebenza ze-400-ukungaphumeleli akukho kuyilo. Ikwisithuba phakathi kokucaciswa kunye nokwenziwa.
Sizibonele mathupha: i-OEM yaseMntla yaseMelika yala iintsimbi ezintathu ezilandelelanayo ezilandelelanayo-kungekhona ngenxa yempazamo ye-dimensional, kodwa ngenxa yesakhiwo senkozo esingahambelaniyo kufuphi nesango. Oyena nobangela? Ukulandelelwa kwemathiriyeli ekrwada okungangqinwanga kwaye akukho nqubo yokugawulwa kwembali ye-thermal. Eso siganeko sayitshintsha indlela esijongana ngayo nayo yonke intsebenziswano yefektri yentsimbi engatyiwa eQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Asiyiphathi insimbi engenasici njengempahla yorhwebo. Siyiphatha njengenkqubo esebenzayo-apho ikhemistri, izinga lokuqina, uxinzelelo lwe-machining-induced residual stress, kunye nengqibelelo yomhlaba kufuneka ihambelane phantsi komsebenzi omnye olawulwayo.
Iintsika ezine zeMveliso yeNsimbi engenaNsimbi ethembekileyo
Ukuthembeka kuqala ngaphambi kokugalela kokuqala. Iqala ngokudityaniswa ngabom-kungekhona ukuphosa i-siled, i-machinening, okanye ukuhlolwa, kodwa ukuphunyezwa okuhambelanayo kwiintsika ezine ezingaxoxisaniyo:
- Imfezeko yezinto ngoYilo: Sifumana i-ingots zensimbi ezingenasici eziqinisekisiweyo kwi-ASTM A743 / A744 (CF8M, CF3M), i-AMS 5387, kunye ne-alloys esekelwe kwi-cobalt ye-T800-kunye neengxelo zovavanyo olupheleleyo lwe-mill kunye nokulandelwa kwenombolo yokushisa. Akukho ngaphandle. Iqela lethu lobuchwephesha liphonononga amaxwebhu edatha yesinyithi *phambi kokufakwa kweodolo, iqinisekisa ukulingana kwekhabhoni, umxholo we-ferrite, kunye noluhlu lwe-delta-ferrite ngokuchasene neemfuno zokudinwa kwesicelo.
- Inkqubo yokuSasa Ukuziphatha: Ukuchithwa kwesanti kulawula izindlu ezinkulu (umzekelo, imizimba ye-piston pump cylinder ukuya kwi-120 kg); ukuphosa utyalo-mali kubamba iindonga ezibhityileyo, iijiyometri ezintsonkothileyo njenge-AMS 5387 imilomo. Okubaluleke kakhulu, silawula amazinga okupholisa ngokujongwa kweqondo lokushisa-kungekhona iimeko zevenkile-kwaye siqinisekisa ukulinganisa ukuqinisa (usebenzisa i-MAGMASOFT®-i-gating enolwazi) kwintsapho nganye entsha.
- Umatshini ohlonipha iMetallurgy: I-CNC ayikho nje malunga nokunyamezela. Kwinsimbi engenasici, imalunga nokuphepha ukuqina komsebenzi kunye ne-micro-cracking. Sisebenzisa i-RPM ephantsi, izicwangciso eziphezulu zokutya kunye nezixhobo ze-carbide ezifakwe kwi-PVD, ukuhanjiswa kwe-coolant ekujoliswe kuyo kwindawo yokucheba-kungekhona i-chip-kunye ne-annealing mandatory-relief annealing * phambi * kokugqibela kwe-OD / ID ukujika kwiindawo ezibalulekileyo zokutywinwa.
- Umgangatho uhlonyelwe, awuhlolwanga: Izikena ze-CMM zenzeka emva kokugrumba *kunye* emva kokugqiba-kungekhona nje kwi-QA yokugqibela. Uburhabaxa bomphezulu (Ra ≤ 0.8 µm ebusweni bokutywinwa) buqinisekiswa ngeeprofilometers zoqhagamshelwano ezilinganiswe yonke imihla. Iqashiso ngalinye lifumana i-PMI (ukuchongwa kwezinto ezilungileyo) kunye nobunzima bemephu kuwo wonke amacandelo anqamlezileyo. Akukho nto ngenqanawa ngaphandle kobukhulu obupheleleyo, iikhemikhali, kunye nezigodo zokulandela umkhondo.
Kutheni le nto "iFactory yeStainless Steel" ingekho nje malunga ne-alloy
Abanye bacinga ukuba intsimbi engatyiwa iqinisekisa ukuxhathisa umhlwa. Kodwa ukuphoswa kwe-CF8M nge-22% yechromium kunye ne-12% nickel iyasilela ngokukhawuleza ukuba imimandla yayo ye-interdendritic iyahlula i-molybdenum-okanye ukuba umatshini ushiya amasuntswana entsimbi afaka i-pitting. Siye salinganisa ukuqaliswa kokuphonswa kwekloridi kwiindawo “ezingenabala” kwiiyure ezingama-72 zokuvezwa kwesitshizi setyuwa xa ungcoliseko lomphezulu lungakhange lususwe nge-citric acid passivation *emva* komatshini.
Yiyo loo nto umzi-mveliso wethu wensimbi engenasici ungayeki ukuphosa. Ibandakanya unyango lwe-atmospheric elawulwayo yokushisa (isisombululo se-annealing kwi-1040-1120 ° C kunye nokucinywa kwamanzi okuqinisekiswe yi-thermocouple arrays), i-electropolished finishes for pump internals, kunye nokucocwa kwe-ultrasonic kuqinisekiswe kwi-ISO 14644 i-Class 7 ye-particulate limits. Ukumelana nokubola akuyonto yendalo-yenziwe ngobunjineli, iqinisekisiwe, kwaye ibhaliwe.
Ukuqinisekiswa kwehlabathi lokwenyani: Ukusuka kuMzobo ukuya kwi-Deployment
Umvelisi wezixhobo ze-hydraulic waseYurophu udinga i-24 imizimba yevalvu yentsimbi engenastainless-inye i-orifices yemitha yangaphakathi emithandathu, ± 0.01 mm ukunyamezela indawo, kunye ne-zero subsurface porosity. Ukucaphula okusemgangathweni kuya kuthatha iintsuku ezili-11. Endaweni yoko, iinjineli zethu ziqhube uhlalutyo lokupakisha lwe-GD&T *ngexesha* lenqanaba le-RFQ, zaphawula iingxabano ezimbini zesakhelo sereferensi yedatha, kwaye zacebisa ulandelelwano oluhlaziyiweyo lomatshini olwanciphisa ubalo lokuseta ukusuka kwisihlanu ukuya kwisithathu-ixesha lomjikelo wokusika ngama-37% ngaphandle kokuncama ukuchaneka.
Waba yintoni umphumo? Ukuvunywa kwenqaku lokuqala ngoSuku lwe-18. Imveliso epheleleyo enikezelwa kwiintsuku ze-42-kubandakanywa novavanyo olutshabalalisayo nge-ASTM E165 kunye nokuhlolwa kwe-radiographic nganye ye-ASME BPVC yeCandelo V. Akukho kuphinda kusebenze. Akukho kulibaziseka. Ayilothamsanqa elo. Ukuhlanganiswa okuthe nkqo: iqela elifanayo liphatha uyilo lwepateni yokuphosa, ukuqinisekiswa kweprogram ye-CNC, kunye novavanyo lokugqibela olusebenzayo kwi-custom-built 5,000 psi hydraulic test rig.
Ukukhetha Iqabane Elingaphaya Kwencwadana
Xa uvavanya umzi-mveliso wentsimbi, buza imibuzo emithathu ngaphandle kweempendulo zephepha elithile:
- Ngaba ungandibonisa iilogi ezintathu zokugqibela zonyango lwe-AMS 5387-kuquka ixesha lokufunxa, iirempu zerempu, kunye nokucima ubushushu obuphakathi?
- Ukuqinisekisa njani ukungabikho kokushwabana kancinci kumacandelo ashinyeneyo >50 mm? (Ingcebiso: I-X-reyi iyodwa iyayiphosa i-microporosity; siyidibanisa ne-metallografi kwiisampulu ezicandiweyo.)
- Bubuphi uburhabaxa obuphezulu obuvumelekileyo kubuso obutywiniweyo obunomatshini-kwaye kukangaphi uhlengahlengisa iprofilometer yakho?
Ukuba impendulo ayicacanga, igeneric, okanye iimbekiselo "standard practice," qhubeka ujonge. Imveliso ethembekileyo yensimbi engenasici ayinazo iindlela ezimfutshane eziqhelekileyo. Inamanyathelo abhaliweyo, aphindaphindwayo, anokufundeka—ngamaxesha onke.
EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ukuthembeka akuthenjiswa. Kuqinisekisiwe-kwisakhiwo sengqolowa, kwingxelo ye-CMM, kwi-curve yovavanyo loxinzelelo. Sakha amacandelo entsimbi engahambelaniyo nezinto ezifunekayo. Bagcina ukusebenza apho ukungaphumeleli kungeyona inketho. Kuba kwiinkqubo ze-hydraulic, ioyile kunye neevalvu zegesi, kunye ne-winch shafts yemoto yobunjineli, isinyithi asifumani thuba lesibini.
