Inkomoko y'uruganda N04400 ntabwo ari ugushaka amagambo yo hasi-ni ukurinda ubunyangamugayo bwibintu mbere yuko imashini itangira. Twabonye amazu menshi ya pompe yamenetse mugihe cya hydrotesting kuko icyemezo cyurusyo nticyahuye nukuri kwangirika kwangirika. Ku kigo cyacu cya Qingdao, buri fagitire ya N04400 - yaba kuri AMS 5387 yujuje ibyicaro bya cobalt-nikel ya valve cyangwa intebe ya T800-alloy winch shaft - ikorerwa igenzura ryikubye kabiri: isesengura rya spekrometrike * na * ASTM B164 yipimishije kuri tombora imwe. Nuburyo twirinda ibintu "byemejwe ariko byangiritse" bitesha igihe OEM.
Kuki "uruganda rwa N04400" bisobanura ibirenze guta cyangwa kuzunguruka
Ukuri N04400 kwukuri gushingiye kubintu bitatu bidashobora kuganirwaho: kugenzurwa gukomera, gutandukanya kugabanya, hamwe namateka yubushyuhe. Abatanga ibicuruzwa benshi bandika ibikoresho nka "N04400" nyuma yo kugenzura ibanze-ariko bakareka kwemeza microstructure. Mu myitozo, ibyo biganisha ku mashini idahuye: icyiciro kimwe gikata neza kuri 85 m / min; ibizakurikiraho kuri 45 m / min, guhatira ibikoresho guhindura hagati. Uruganda rwacu N04400 ruhuza vacuum induction gushonga hamwe no kugenzura icyerekezo gikomeye. Buri ingot yashushanyijeho umwanya wa dendritic no gukwirakwiza sulferi - amakuru dusangira nabakiriya mbere yo gukata. Kubitutu byingutu bisaba <0.5 μ m Ra hejuru kurangiza, ibi bikuraho imirimo idateganijwe. Kububiko bwa pisitori ya piston pompe ikora kuri 4000 psi, irinda microcrack gutangira munsi ya cyclic.
Aho bisanzwe N04400 igaragara bigufi-nuburyo tuziba icyuho
ASTM B164 isobanura imipaka ya N04400 yimiti-ariko ntacyo ivuga kubijyanye nimbibi za karbide yimvura igwa. Inganda zimwe zitanga ibikoresho muburyo bwihariye ariko bikananirwa kwipimisha byihuse mumazi ya chloride ikungahaye kuri chloride. Turabikemura dufata ububiko bwa N04400 kuri 650 ° C mumasaha 2 nyuma ya annealing, hanyuma gukonjesha ikirere. Ibi bihindura matrike ya Ni-Cu irwanya guhitamo mugihe irinda guhindagurika. Abakiriya batanga raporo 3.2 life igihe kirekire cyigihe cyo gukora mumateraniro ya pompe yo hanze ukoresheje ubu buvuzi. Icy'ingenzi, ntabwo dufata ibyiciro byose kimwe: ibirimo sulfure> 0.005% bikurura igihe cyo gufata igihe; ibisigisigi bya titanium> 0,02% igipimo cyo gukonjesha. Ihinduka-nyaryo risaba igihe-nyacyo cyo gusubiza-ntabwo ari urupapuro rwimikorere.
Kuva kumurongo mbisi kugeza kubutumwa-bukomeye igice: inyungu ihagaritse
Abatanga N04400 benshi bahagarara kubitangwa. Dutangirira aho - kandi dutunze buri ntambwe nyuma. Mugihe OEM yu Burayi yari ikeneye 120 ya cobalt alloy nozzles kugirango itere ubushyuhe bwo hejuru, batwoherereje igishushanyo gifite ± 0.01 mm guhamagara GD&T hamwe nigihe ntarengwa cyibyumweru 10. Dore uko byagenze: aba metallurgiste bacu bagenzuye mbere ya billet ya N04400 ishyushye-ikora neza; itsinda ryacu rya CNC ryiganye chip imitwaro ikwirakwizwa murwego rwimbere rwimbere; itsinda ryacu rirangiza ryemeje ibipimo bya electropolish kurwanya ASTM A967 ibisabwa. Nta ntoki. Nta muntu wa gatatu utinda. Buri genzura-uhereye kubintu byinjira CMM scan kugeza kuri raporo yanyuma-yikizamini-ibaho mumutwe umwe. Niyo mpamvu 73% byibyo N04400 byateganijwe bisubiramo kwiruka kubintu bimwe bikora.
Guhitamo umufatanyabikorwa wawe N04400: ibibazo bitatu byerekana ubushobozi
- Urashobora kunyereka raporo yubushakashatsi butatu bwanyuma raporo yikizamini-harimo kwangirika hagati yimibumbe (ASTM G28 Method A) hamwe no gupima buhoro-buhoro muri 3.5% NaCl? Niba bashidikanya, QA yabo ihagarara muri chimie.
- Ukora imashini N04400 murugo-cyangwa hanze nyuma yo kubyara? Gutunganya hanze yikibanza bisenya amateka yubushyuhe kandi bishobora kwanduza hejuru.
- Niyihe gahunda yawe ndende ya N04400 ikora-kandi ni ubuhe buryo bwo gutsindwa wakuyeho ukoresheje itera? Ibisubizo byerekana niba biga mumibare yumurima cyangwa ibyemezo byubwato gusa.
Twakoze gahunda imwe ya N04400 pompe yimyaka umunani. Ibyiciro byambere byerekanaga micro-piting kuri intera intera. Impamvu? Gitoya ya manganese oxyde ikora nkibitera guhangayika. Igisubizo: wongeyeho calcium ivura gushonga hanyuma utangiza ultrasonic immersion isukura mbere yo gutunganya. Ntabwo ari ugukora gusa-ibyo ni igisonga cya metallurgical. Mugihe ukeneye umusaruro wizewe Nickel Alloy 400, tangira aho inkuru yibikoresho itangirira-ntabwo ariho inyemezabuguzi ikorera.
