Iyo pompe hydraulic yananiwe mu ruganda rwa peteroli yo hanze - cyangwa igitutu cya valve cyacitse mugihe cyo kwipimisha cyane - intandaro akenshi ituruka kumyanzuro imwe: guhitamo ibikoresho. Uruganda rwa Cobalt rushingiye kumashanyarazi ntabwo arirwo rutanga gusa. Nubwishingizi bukora kuri sisitemu aho ihungabana ryumuriro, kwambara nabi, hamwe nu mutwaro wa 20.000-psi ukuraho margin kubwikosa.
Kuki cobalt alloys isaba inganda zihariye - ntabwo ari imashini rusange
Cobalt-chromium superalloys nka AMS 5387 na T800 ntabwo "bigoye imashini." Barwanya metallurgurgie: akazi-gakomeye vuba kurenza igikoresho gishobora gukata, gukingira ubushyuhe buhagije kugirango umutego ushushe, kandi microstructural yunvikana kumaganya asigaye cyangwa gukonja kutaringaniye. Twabonye amaduka agerageza T800 nozzles ku ruganda rusanzwe rwa CNC-gusa gukuraho 60% yingingo ya mbere ikomoka kuri micro-crack mugihe cyo kuvura ubushyuhe bwa nyuma. Intsinzi isaba ibirenze gushiramo karbide. Irasaba guhuza ibikorwa byogukora, gutunganya ikirere cyimbere mbere yo gukomera, hamwe na CMM iyobowe na adaptive ibikoresho byerekana uburyo bwo gutandukana mugihe nyacyo mumazu ya pompe.
Niyo mpanvu cobalt yukuri ishingiye kumavuta yimashini ibice byuruganda ubushobozi butangirira hejuru-mubintu bikurikirana. Buri fagitire ya AMS 5387 dutunganya itwara raporo yuzuye yikizamini, hamwe nisesengura ryerekanwe kuri ASTM E1099 nubunini bwimbuto byemejwe kuri ASTM E112. Nta gusimbuza icyiciro. Nta "ntera ihwanye". Niba igishushanyo cyawe kigaragaza AMS 5387, urabona AMS 5387 - ntabwo isa na 0,3% munsi ya chromium kandi yangiritse ubukana.
Ubushobozi bune budasubirwaho inyuma yubutumwa bukomeye bwa cobalt
Umufatanyabikorwa wizewe agomba gutanga ubudahwema - atari rimwe gusa, ariko murwego rwo hejuru rwibikorwa 500 hamwe nimyaka 10 yo gutegereza ubuzima. Ubu ni ubushobozi twemeza mbere yo gusubiramo:
- Iterambere rinini binyuze mu gutunganya ibivange: Umucanga-cobalt alloy plugs igabanuka bitateganijwe. Igisubizo cyacu? Ishoramari-ryibanze hamwe na CNC yarangije gufunga - gufata ± 0.015 mm kuri diametero 120-mm nta kugoreka nyuma.
- Ubusugire bwubuso hejuru yubuso: Ra 0.4 µm ntacyo bivuze niba munsi yubutaka micro-gutaburura itumira umunaniro hakiri kare. Dukoresha bike-RPM, ibiryo byinshi byo kurangiza byuzuye hamwe nibikoresho byavuwe-kandi tugenzura ubusugire bwubutaka dukoresheje amashusho ya SEM yambukiranya ibice ku ngingo za mbere.
- Kwemeza imikorere birenze GD&T: Cobalt alloy nozzle ntabwo yemerewe nyuma yo kugenzura CMM. Ikorerwa kalibrasi ya 350 ° C, igeragezwa ryisuri hamwe na 80-grit silika slurry kuri 12 m / s, hamwe nubugenzuzi bwa ultrasonic kugirango ibone imbere muri ASTM E1961 Urwego rwa 3.
- Gukurikirana ikarita yo gusesengura kunanirwa: Buri gice cyoherejwe hamwe na QR yanditseho icyemezo gihuza nimero yubushyuhe bwibikoresho fatizo, ibiti byizunguruka, itariki yo kugenzura, hamwe nindangamuntu. Iyo gutsindwa kumurima bibaye, injeniyeri ntibakeka-batandukanya imizi mumasaha, ntabwo ibyumweru.
Aho abatanga rusange bananiwe-kandi abahanga batanga
Bamwe mu bakora inganda bafata amavuta ya cobalt nk "ikindi cyuma kidasanzwe." Basubiramo bashingiye kuburemere, ntabwo amateka yubushyuhe. Batanga casting kubandi bantu badafite uburambe bwa cobalt - hanyuma bakarwana nuburyo bwa dendritic idahuye. Basibye guhagarika umutima mbere yo gutunganywa bwa nyuma, bigatera intambara mu nzu ya pisitori ya pisitori nyuma yo guterana.
Twagize abakiriya bahinduranya umushinga wo hagati nyuma yo kuvumbura uwabatanze mbere yakoresheje ibikoresho bya cobalt byongeye gukoreshwa hamwe na profil ya element element idasobanutse. Igisubizo? Kwishongora imburagihe muri winch center shaft rollers munsi ya cyclic torsional umutwaro. Igisubizo cyacu nticyari ugusimbuza gusa - cyari isubiramo ryitwa metallurgical, kuvugurura ibihe byo kuvura ubushyuhe, no guhindura inzira yo gutanga ibicurane muri gahunda ya CNC. Nibyo guhuza vertical: guta, gutunganya, kuvura ubushyuhe, na NDT munsi yinzu, hamwe nubumenyi busangiwe-ntabwo ari amaboko.
Guhitamo uruganda rwa cobalt rushingiye kumashanyarazi: ibibazo bitatu bitandukanya abafatanyabikorwa nabacuruzi
Mbere yo gusinya NDA, baza ibi - ntabwo ari ibisubizo byamamaza, ahubwo nibimenyetso byanditse:
- Ati: “Nyereka ubufindo bwawe bwa nyuma bwa AMS 5387 - imashini zisya, ibiti bivura ubushyuhe, na raporo ya nyuma ya CMM.” Guhuzagurika byerekana impapuro, ntabwo ari amasezerano.
- "Nubuhe burebure bwawe budashyigikiwe na T800 ya shitingi kuri mm 45 - kandi nigute ushobora kugenzura neza mugihe uhindutse?" Imipaka nyayo yisi igaragaza gukura kwinzira.
- Ati: "Niba igishushanyo mbonera cyamazu ya pompe gisaba urukuta rwa mm 0,8 hafi ya 90 ° imbere, ni ubuhe buryo ntarengwa bwo gukora - kandi nigute ushobora kugenzura ubunyangamugayo bwuzuye muri iyo zone?" Ibi bizamini byo gutoranya ubuhanga, ntabwo ari ubuhanga bwo gutunganya gusa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora uruganda rukora ibicuruzwa muri Qingdao rwemejwe na ISO 9001: 2015, hamwe na selile yakazi ya cobalt-alloy yabugenewe, murugo optique yohereza ibyuka byangiza, hamwe na mashini yo gupima imashini ikora PC-DMIS. Inshingano zayo zirimo cobalt alloy nozzles ya pompe yameneka yumuvuduko mwinshi, ibice bya pompe AMS 5387 byujuje ibisabwa API 6A, hamwe nibikoresho bya T800 byabigenewe kubigenzura. Isosiyete ikorera abakiriya b’inganda muri Amerika ya Ruguru, Uburayi, no mu majyepfo y’amajyepfo ya Aziya - itanga prototypes mu minsi 12, ibicuruzwa bito bito mu byumweru 6-8, hamwe nibikoresho byuzuye kandi byubahirizwa byubatswe muri buri cyiciro.
Ejo hazaza h'ibikoresho bya cobalt bishingiye ku bikoresho bya ruganda ntabwo biri mu mashini nini - ahubwo ni uguhuza gukomeye hagati ya metallurgie, imashini ya fiziki, no kwemeza imikorere. Mugihe igitutu cya sisitemu kizamuka kandi intera intera ikaguka, itandukaniro riri hagati yemewe ninshingano-ntizipimwa muri microne. Bizapimwa mugihe cyo hejuru, umutekano wumutekano, nigiciro cyose cya nyirubwite. Hitamo ukurikije.
