Ubushyuhe bwo hejuru cyane bwa termocouples burananirana - ntabwo buturuka ku nsinga zidakwiye, ahubwo buturuka ku miyoboro yo gukingira, yangiritse, cyangwa idahuye. Twabibonye mu ruganda rukora ibyuma bishyushya itanura aho 1200 ° C izunguruka yangiza amaboko ya alumina mu mezi atandatu. Twasimbuye imiyoboro ya cobalt-alloy kuri pompe ya offshore nyuma yo kwinjira mumazi yinyanja yahinduye intera ya flange. Ukuri-kwisi kwizerwa gutangira kera mbere yuko sensor ihagarikwa: itangirana numuyoboro urinda.
Kuki "uruganda rukingira uruganda rwa Thermocouple" atari ijambo ryishakisha gusa-ni ibisobanuro
Abaguzi benshi bafata imiyoboro yo gukingira nkibikoresho rusange. Ntabwo aribyo. Umuyoboro ukorera mu ziko rya laboratoire unanirwa cyane mu nzu ya pompe ya hydraulic ya pisitori ihura nubushyuhe bwumuriro, kunyeganyega, hamwe namavuta yuzuye uduce. Uruganda rukwiye ntiruterera cyangwa imashini silinderi gusa. Ikora inzitizi - ihagaze neza kuri 1100 ° C, ihuza ibyuma na metero ya termocouple, kandi ikanashyirwa mumashanyarazi kugirango irwanye umunaniro kuri flange igenda.
Ibyo bisaba ubushobozi butatu butavugwaho rumwe: icya mbere, kumenya ubuhanga bukomeye cyane nka AMS 5387 cobalt-chromium na T800 yo mu rwego rwa superalloys - ibikoresho birwanya kunyerera ariko bisaba kugenzura neza ubushyuhe; icya kabiri, guhuza verticale yo gushora imari * na * byinshi-axis CNC ikora kugirango ifate kwihanganira mm 0,02 mm hejuru yikimenyetso gikomeye; icya gatatu, ibikoresho byuzuye bikurikirana - kuva raporo yipimishije ryuruganda rwemeza kugeza ubukana bwihariye no kugenzura imiterere.
Uburyo bune bwo kunanirwa - nuburyo uruganda rwujuje ibisabwa rubuza buri
Turakurikirana kunanirwa mumashanyarazi hirya no hino mumashanyarazi yo muri Amerika ya ruguru hamwe na peteroli ya Aziya yepfo. Intandaro enye ziganje:
- Ubushuhe budahuye. Igisubizo: guhuza ibice byagenzuwe hakoreshejwe coefficient-yo-kwagura-kwaguka (CTE) guhuza - ntabwo kubahiriza amazina gusa.
- Isuri. Igisubizo: gukomeretsa inama geometrie (urugero, conical cyangwa hemispherical) yakozwe * nyuma * yo kuvura ubushyuhe-ntabwo yashyizwemo.
- Gutesha agaciro kashe: Gutakaza gasketi gutakaza ubushyuhe bwinshi bituma itangazamakuru ryinjira. Igisubizo: Igitugu cyahinduwe neza hamwe nigitambaro cyo hejuru Ra ≤ 0.4 µm - byagenzuwe na optique profilometrie, ntabwo ari ubugenzuzi bugaragara.
- Kugabanuka: Imiyoboro irambuye cyangwa ikarishye mugihe cyigihe kirekire, ikuramo thermocouple mubwimbuto bwayo bwimbitse. Igisubizo: guhangayikishwa no guhagarika umutima kuri ASTM A967, hagakurikiraho CMM ishingiye nyuma yubushyuhe bwo kuvura igororotse kandi yibanze.
Ibi ntabwo ari impungenge. Niyo mpamvu umukiriya umwe yahinduye abatanga ibicuruzwa nyuma yicyiciro cya gatatu gikurikiranye cya Inconel 600 yerekanaga umuheto wa mm 0,15 kuri 900 ° C-ukarenga ASME B31.1 imiyoboro ya 300%.
Niki gitandukanya utanga isoko ninganda zo gukingira thermocouple
Utanga ibicuruzwa yohereza imiyoboro. Uruganda rutanga ibyiringiro bya sisitemu. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Bivuze ko isuzuma ryubwubatsi ritangirana nigishushanyo cya GD&T - ntabwo ari PO yawe. Dutondekanya ibyago hakiri kare: uburebure bwa mm 1.5 burashobora kurokoka umuvuduko uhagaze, ariko isesengura ryumunaniro wa vibrational ryerekana resonance kuri 210 Hz mugiterane cya pompe. Turasaba icyifuzo cya mm 2.0 cyashushanyijeho urukuta hamwe na mashini yaho yo kuzigama ibiro-byemejwe na FEA mbere yo gukoresha ibikoresho.
Ikigo cyabo cyujuje ISO gikora amazu yombi yumucanga kubushakashatsi bwamashyiga manini ya diameter hamwe nogushora imari kugirango bakurikirane turbine. Buri cyiciro cya cobalt-nikel gikorerwa isesengura rya spekitografiya, ikizamini cyo kwangirika hagati ya ASTM A262 Imyitozo E, hamwe no kugenzura ibintu mucyumba n'ubushyuhe bwa serivisi. Nta "bikoresho byemewe" bidafite amateka yubushyuhe. Nta pasiporo igaragara idafite CMM ikurikirana kubipimo bya NIST.
Ntibabika imiyoboro "isanzwe". Babika AMS 5387 fagitire, T800 ingots, na 316L idafite umwanda - hanyuma imashini, imashini, cyangwa imvange-itondekanya buri cyegeranyo gikenewe, ntabwo ari nomero ya catalog.
Guhitamo umukunzi wawe: ibibazo byerekana ubushobozi
Baza ibi mbere yo gusaba amagambo - urebe uburyo basubiza cyane:
- Ati: "Urashobora gutanga umurongo wo kwagura amashyanyarazi ya AMS 5387 uri hagati ya 25 ° C na 1100 ° C-ukemeza ko yapimwe kumurongo umwe ukoreshwa mu musaruro?"
- "Utwereke raporo zawe eshatu za nyuma za CMM kuri mm 12 ya OD × 1.5 mm y'urukuta - cyane cyane kuzenguruka kuzenguruka hagati no hagati."
- "Nigute ushobora kugenzura ubudahangarwa bwa kashe nyuma yo gutunganywa bwa nyuma? Ikizamini cyumuvuduko? Helium yamenetse? Irangi ryinjira mumaso ya kashe?"
- "Niba porogaramu yacu isaba inguni ya taper yihariye ku musozo winjizamo, urayikora mbere yo kuyivura mbere cyangwa nyuma yubushyuhe - kandi ni ubuhe buryo ushobora kugeraho kuri ubu buryo?"
Igisubizo kidasobanutse cyerekana ibimenyetso byishingikiriza kumurongo wa gatatu wamazu cyangwa hanze yubusa. Ibisubizo, amakuru ashyigikiwe nibisobanuro bivuze ko uvugana na uruganda rukingira uruganda.
Kwizerwa ntabwo byubatswe muri sensor. Yakozwe muri tube-kandi itangwa nabafatanyabikorwa bafata milimetero zose zubugari bwurukuta, buri cyiciro cya taper, buri cyerekezo cyimbibi zintambwe nkibikorwa byingenzi. Nibyo abakiriya basanzwe biteze. Nibisanzwe QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ihura-burimunsi, murwego rwo gutanga amasoko kwisi yose, kubisabwa aho gutsindwa atari amahitamo.
