Iyo abajenjeri bagaragaje ibyuma bitagira umuyonga baterana uruganda, ntibategeka ibice gusa - barinda umutekano muke munsi yumuvuduko wa hydraulic 300, kurwanya ruswa mukarere ka gaze gasharira, hamwe nuburinganire bwa microstructural nyuma yo kuvura ubushyuhe. Niyo mpamvu twabonye abakiriya basubiramo baturutse mu bigo bya serivisi by’amavuta yo muri Amerika ya ruguru bagaruka bafite ibishushanyo mbonera byamazu ya pompe nyuma yibyumweru 12 gusa nyuma yo gutangwa bwa mbere: bagerageje kurangiza hejuru ya AMS 5387 cobalt alloy nozzles muburyo bwo kwisubiraho-basanga microcracking zeru ku irembo.
Impamvu Imyitwarire Yumubiri Ihitamo Guhitamo Inzira-Ntabwo ari Igiciro gusa
Gushora ibyuma bidashora imari birananirana mugihe amakipe abifata nkicyuma cya karubone. Twarebye imishinga itatu ihagarara kubera ko abashushanya bagaragaje 316L ya casting kumazu ya pisitori ya pisitori yo hejuru cyane tutabaze gukomera kwa anisotropy. Igisubizo? Imashini ya mashini yatwaye mm 0,04 muri kwihanganira GD&T nyuma yo kugabanuka. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Inzira yacu itangirana no kwerekana amashyuza-ntabwo asubiramo. Kuri buri cyuma gisaba ibyuma bidafite ibyuma bisabwa, twigana inzira yo gukomera dukoresheje MAGMAsoft kugirango dushyireho ibyago aho kugaburira dendritic byishyura kugabanuka kwaho. Nuburyo dufata ± 0,025 mm kuri Ø120 mm ya silinderi ya bore indangamuntu tutabanje kuyikora-birakomeye mugihe umubyimba wurukuta wagabanutse kugera kuri mm 8.3 munsi yicyambu.
Ibi ntabwo ari amahame. Igihembwe gishize, imodoka yubudage yubudage OEM yari ikeneye winch center shaft rollers muri 17-4PH ibyuma bitagira umwanda. Ababitanze mbere batanze ibice 12% kubera microporosity interdendritic hafi yo gukonjesha. Twahinduye amarembo ya geometrie, tugabanya ubushyuhe bwo gusuka kuri 42 ° C, hanyuma dushyiramo icyuma gifashwa na vacuum. Umusaruro wasimbutse kugera kuri 94%. Itandukaniro ntabwo ryari ibikoresho byiza-byari disipuline ya metallurgiki ikoreshwa mbere yuko ibishashara byambere bicapwa.
Aho Vertical Kwishyira hamwe ikemura muburyo bwo kunanirwa
Bamwe mubatanga isoko yohereza imashini kugabanya ibiciro. Ibyo bitera ingaruka zitagaragara: umubiri wumucanga 304 wumubiri wa valve ushobora kunyura kuri NDT, ariko hanyuma ukarwanya mm 0.08 mm mugihe CNC ihindutse kuko imihangayiko isigaye ntiyorohewe hagati yo guta no gutunganya. Mu kigo cyacu cyujuje ISO muri Qingdao, itsinda rimwe rishinzwe gukina, gutunganya ubushyuhe, no gutunganya imashini nyinshi. Turakurikirana buri kintu cyose dukoresheje ibintu byuzuye - kugeza kumubare ushonga wa ingot 316L yemewe hamwe nigitereko cyizunguruka kugirango gikemurwe kuri 1040 ° C ± 5 ° C.
Igenzura rifite akamaro cyane kubice bivangavanze. Tekereza kuri T800 ya cobalt ishingiye kuri alloy pump fondasiyo: guteramo igishoro cyishoramari, igisubizo kivuwe, hanyuma kigakorwa hamwe na 5-axis ihuza ibice byo hejuru. Niba gutara no gutunganya bibera ahantu hatandukanye, amateka yubushyuhe adahuye atera imbaraga zidahuye kuruhande. Ibikorwa byacu bihurijwe hamwe bituma imbaraga zitanga umusaruro muri ksi 102-108 ksi zose zipimishije - ndetse no kuri kg 42 hamwe na 3.2 mm zoroheje-urukuta.
- Ibice bya CNC byakozwe: Bore-kwihanganira gukomera (± 0.015 mm) kumazu adakomeye.
- Ibikoresho bya Cobalt-nikel: AMS 5387 nozzles irokoka 15,000+ kuri 450 ° C.
- Ibyuma: Ibyuma bitwara ibyuma (ADI) bitwara ibyuma bifite imbaraga za MPa 1200
- Ibyuma kandi bidafite ingese: ASTM A743 CF8M ifite ububiko 200 kuri -40 ° C.
Icyo "Custom" bivuze mubyukuri mubikorwa byo hejuru
“Custom” ikoreshwa nabi. Uruganda rwukuri rutagira ibyuma rutunganya ibyuma ntirukoporora igishushanyo cyawe gusa - rirwanya ibitekerezo. Igihe uruganda rukora pompe yo mu majyepfo y’iburasirazuba bwa Aziya rwatwoherereje igishushanyo cya 304 cyo gushushanya serivisi z’amazi yo mu nyanja, isuzuma ry’ubuhanga ryacu ryerekanye ibibazo bibiri: ibyago byo guterwa na chloride biterwa no gusana ahantu hasanwa, hamwe no gushyira ibyago bidahagije kuri flam 110 mm. Twasabye guhindukira kuri duplex 2205, twongera gushushanya sisitemu yo kwinjira, hanyuma twongeraho igisubizo nyuma ya weld. Igihe cyo kuyobora cyiyongereyeho iminsi 5 - ariko igipimo cyo kunanirwa kumurima cyamanutse kiva kuri 7.2% kigera kuri zeru mubice 1200.
Twemeza gukora mbere yo gukoresha ibikoresho. Ubusobanuro bwa GD&T burimo kugenzura imiterere ya datum igerwaho na CMM-ntagikorwa gitunguranye mugihe igice cya mbere kigenzuye. Kuri geometrike itari isanzwe nka cobalt yometse kumashanyarazi hamwe numuyoboro wo gukonjesha imbere, dukora casting simulation, hanyuma imashini ikora igishushanyo mbonera kuri DMG MORI NTX 1000, kugenzura impande zikomeye hamwe na optique profilometrie mbere yuko umusaruro utangira.
Kureba imbere: Aho Gutoranya Byerekanwe
Imipaka ikurikira ntabwo ari itanura rinini-ni uguhuza gukomeye hagati ya casting physics n'imikorere ikora. Turimo kwagura R&D muburyo bwa casting-mashini ya Hybrid: gushira ibice bya cobalt idashobora kwangirika byimbere kuri substrate idafite ingese hifashishijwe ibyuma bya laser, hanyuma bikarangira muburyo bumwe. Ibi bivanaho intege-umurongo zintege nke muburyo bwa gakondo. Icyarimwe, twongeyeho ASME BPVC Igice cya VIII Div. Icyemezo 2 cyujuje ibyangombwa bikenerwa nubwato bukenewe mumishinga yingufu zi Burayi.
Niba porogaramu yawe isaba ibyuma bidafite ibyuma byerekana inganda zifata metallurgie nka injeniyeri-ntabwo ari amasoko-ukeneye abafatanyabikorwa bapima intsinzi mugupima ibizamini, ntabwo byoherejwe ku gihe gusa. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. itanga ibice bigoye, ubutumwa-bwibanze aho uburinganire bwukuri, kugenzura microstructure, hamwe no kwizerwa kumikorere ntabwo intego zitandukanye-zubatswe mubikorwa byose.
