Iyo ushakishije ibyuma bisobanutse neza kuri sisitemu ya hydraulic, ibikoresho bya peteroli na gaze, cyangwa inteko zipompa zifite umuvuduko mwinshi, abaguzi ntibakunze kubaza bati: "Ni ubuhe bwoko bw'uruganda rukora ifu ngomba gukorana?" Barabaza bati: "Ese iki gice kizaba gifite 40.000 psi? Irashobora kurwanya guhumeka muri cobalt-alloy nozzle ikora kuri 650 ° C? Ese utanga isoko agenzura microstructure * na * geometrie - atari imwe gusa?"
Igisubizo ntabwo kiri mubyemezo rusange cyangwa udutabo twinshi - ariko muri ubwoko bw'ifu ya ruganda metallurgie mubyukuri ukora inyuma yinyuma. Ntabwo ibikoresho byose byubatswe kugirango bikoreshe AMS 5387 cobalt alloy valve intebe, T800 ishingiye kumuzingo wa shitingi idasanzwe, cyangwa ibyuma byumuvuduko bisaba ubucucike bwa net-hafi * na * ± 0.01 mm CNC yakozwe na kashe. Mubikorwa, twabonye uburyo butatu butandukanye bukora-buri kimwe gifite ubucuruzi bukomeye mubushobozi, kuyobora igihe, ikiguzi, hamwe na tekiniki ya tekiniki.

Izi nganda zibanda gusa kubintu bitoroshye-gutunganya-superalloys-cobalt-nikel, nikel-fer, hamwe nicyuma gisubiza inyuma - ukoresheje imashini isotatike ishyushye (HIP), gucumura vacuum, hamwe n’itanura ryikirere. Birinda ibyuma bya karubone cyangwa ifu ya aluminiyumu. Imbaraga zabo ni metallurgical repetition: buri kintu kinini cya AMS 5387 gikorerwa isesengura rya ogisijeni / azote, kugenzura ingano, no gupima tensile kuri ASTM B988. Ariko ntibakunze gutanga kurangiza. Wakiriye inzu ya silinderi ya HIP'd-hanyuma ugahuza gusya, gutondeka, hamwe no gukomera hejuru ahandi. Ibihe byo kuyobora birenga ibyumweru 12. Twakoranye nabashinzwe gutanga amasoko abiri aho drift ibipimo byabaye hagati ya HIP no gutunganya imashini ya nyuma kubera kwaguka k'umuriro utabaruwe mububiko bwa T800. Niyo mpamvu amaduka ahuriweho afite akamaro mugihe inzu yawe ya pompe ya piston igomba gufunga 35.000 psi * kandi * ikarokoka 10,000 10,000 nta microcracking.

Ubu bwoko buvanga ifu hamwe nibikorwa remezo byo gushora imari hamwe na selile nyinshi za CNC-icyitegererezo cyakoreshejwe na QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Hano, ifu ya metallurgie ntabwo yonyine. Igaburira mu buryo butaziguye nyuma yimashini ikora imashini ya cobalt ikomye. Ikigo gikoresha ISO cyujuje umusenyi nishoramari hamwe na centre ihinduranya ibasha gufata umuhamagaro wa GD&T nkumwanya nyawo ≤0.025 mm kumuzingi wa flange. Byibanze, bemeza ibishushanyo * mbere * ibikoresho - ntabwo nyuma. Mugihe umukiriya wu Burayi yohereje shitingi idasanzwe ya winch center ifite imiyoboro yo gukonjesha idasanzwe, itsinda ryagaragaje ingaruka zishobora kugoreka mugihe cyo gukonjesha no gutanga icyerekezo cyahinduwe nicyatsi kibisi. Igisubizo: ingingo ya mbere yatsinze igipimo cyavuye kuri 62% kigera kuri 98%. Uru rwego rwo gufatanya gukora gusa iyo gukora ifu, gucumura, kuvura ubushyuhe, no gutunganya ibinyabuzima munsi yinzu imwe - hanyuma ugasangira protocole imwe nziza.
3. Imirongo yihuta yo guhuza imirongo (Ibicuruzwa-Urwego, Umubare-mwinshi)
Izi nganda zishyira imbere umusaruro wa tonnage hejuru ya microstructural nuance. Bakoresha imashini izunguruka ku bice 30+ / umunota bakoresheje icyuma kibanziriza icyuma cyangwa ifu idafite ingese, akenshi basiba HIP. Ibice byujuje MPIF Ibipimo 35 byerekana ubucucike - ariko ntibikunze kurenga 7.2 g / cm³ muri geometrike igoye. Kurangiza ubuso ni Ra 3.2-6.3 µm nkuko byacumuye. Babaye indashyikirwa mu mashyamba, ibikoresho, hamwe n’abatwara ibinyabiziga byubaka - ariko birananirana iyo basabwe kwangirika kwangirika cyangwa kwishingira pompe. OEM imwe yo muri Amerika ya ruguru yarahindutse nyuma yo kuvumbura ububobere budahuye muri zone itwara imizigo yumubiri wa hydraulic. Isuzuma rya Micro-CT ryerekanye icyuho gifitanye isano kirenze imipaka ya ASTM E1558 - ntigishobora kugenzurwa nubugenzuzi busanzwe bwa ultrasonic. Niba porogaramu yawe isaba guhagarika zeru imbere muri zone zikomeye, iyi moderi itwara ibyago bitemewe.
Nigute ushobora guhitamo? Tangira ukora - ntabwo ari inzira. Baza: Ese ibice bisaba ubunyangamugayo bwubatswe * munsi yumutwaro uremereye *, cyangwa guhagarara gusa? Kwambara kwambara biterwa no gukomera - cyangwa gukwirakwiza karbide? Kurangiza hejuru bigomba gufunga amazi, cyangwa bikwiye gusa? Noneho uhuze ibyo bisabwa nuburambe bwuruganda rwerekanwe-ntabwo ari udutabo dusaba. IKORANABUHANGA RYA QINGDAO QIANGSENYUAN, kurugero, ntabwo ryamamaza "ifu ya metallurgie ibisubizo." Yanditse inyandiko zubaka: 147 AMS 5387 cobalt alloy pompe ibice byashyikirijwe rwiyemezamirimo wo gucukura hanze ya Q3 2023, buri kimwe gifite ibiti byuzuye byo gutunganya ubushyuhe, raporo ya CMM, hamwe nubushakashatsi bwakozwe murwego rwo hejuru. Ngiyo itandukaniro riri hagati yo gusaba ubushobozi no kubigaragaza.
Urebye imbere, kwihangana cyane ubwoko bw'ifu ya ruganda metallurgie ntibizasobanurwa nibikoresho byonyine-ariko nukuntu bihuza cyane siyanse yibintu, kugenzura inzira, no kwemeza imikorere. Abaguzi bafata ifu ya metallurgie nkagasanduku kirabura bazakomeza kwishyura amafaranga yo gukora, gutinda, no kunanirwa kumurima. Abashushanya uburyo bwo gutsindwa kwabo muburyo bwa ADN ikora itanga isoko - nka HIP + CNC kwishyira hamwe hejuru yumuvuduko ukabije wikimenyetso, cyangwa igisonga cyemewe cyo kuba ibikoresho bya cobalt-nikel-byunguka. Ukuri-kwisi kwizerwa gutangira kera mbere yikinyamakuru cya mbere. Bitangirana no kumenya neza uruganda ruhagaze inyuma yumubare wigice.
