Iyo ba injeniyeri bagaragaje Ibice bya Hastelloy, ntabwo bahisemo gusa ibikoresho-biyemeje gushikama kurwego ruri munsi ya 650 ° C, kurwanya ruswa muri HCl ishyushye cyangwa chlorine itose, no kwihanganira zeru kubijyanye na microstructural idahuye. Niyo mpamvu gushakira ukuri Uruganda rwa Hastelloy ntabwo bijyanye no guhitamo abacuruzi. Byerekeranye no kugabanya ingaruka.
Isi-nyayo itunganya ububabare-ntabwo ari ibitekerezo
Twabonye kunanirwa inshuro eshatu gusubiramo muri pompe OEM hamwe na societe ya serivise ya peteroli: Icya mbere, zone yibasiwe nubushyuhe bwacitse mumibiri ya AMS 5387 cobalt-nikel ya valve nyuma yo guhindukira kwa CNC ya nyuma-biterwa no guhangayika gusigara guterwa no gukonjesha gukabije. Icya kabiri, guhamagarwa kwa GD&T kurenga ku mazu ya pompe ya T800 alloy piston kubera ko uwabitanze yakoresheje umusenyi udafite igisubizo nyuma yo guterwa. Icya gatatu, kurangiza kurangiza kutavuguruzanya kuri cobalt alloy nozzles biganisha ku isuri itaragera mumirongo yihuta cyane - ikurikiranwa na grit guturika bitagenzuwe.
Izi ntabwo ari imanza. Nibimenyetso byubushobozi bwacitsemo ibice: guta byakozwe niduka rimwe, gutunganya nindi, kuvura ubushyuhe hanze bitagenzuwe na metallurgical. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dutunganya imashini ibyo twateye - kandi twemeza intambwe zose zirwanya ASTM A992, AMS 2750, na ISO 8503-2. Nta ntoki. Nta bitekerezo.
Kuki guhuza vertical bihindura byose
Abatanga ibicuruzwa benshi urutonde "Hastelloy machining" nka serivisi. Bake bagenzura urunigi rwuzuye - kuva ibyemezo bya billet mbisi kugeza raporo ya CMM yanyuma. Turabikora. Ikigo cyacu cyujuje ISO gikora ishoramari kumashanyarazi ya cobalt yuzuye uruzitiro ruciriritse, guta umucanga kubishingwe bya pompe nini ya diametre, hamwe na CNC-axis nyinshi kugirango imyanya yihanganira igitutu-byose biri munsi yinzu.
Ibi bivuze ko duhindura casting gushingira kumashanyarazi ya nyuma. Duteganya kuvura ubushyuhe * mbere * bikabije, ntabwo nyuma yo kurangiza. Dushira kurasa gusa aho umunaniro ubuzima bufite akamaro - ntabwo mubice byose. Iyo umukiriya yohereje igishushanyo cyamazu ya pompe ya AMS 5387 hamwe na 0.01 mm silindrike kuri bore ya mm 320, ntitwabivuze. Twigana kugoreka ubushyuhe, kugenzura ingano yimigozi, no gufunga inzira zikurikirana mbere yo gukata ibyuma.
Igenzura rihagaritse ritanga ibisubizo bitatu byapimwe: 22% bike byo kwanga ingingo ya mbere, 40% bigufi biganisha kuri prototypes, hamwe nibice byose bikurikirana kugeza kuri raporo y'ibizamini by'urusyo rwa T800 y'umwimerere.
Aho ubuhanga buhuye nukuri gushira mubikorwa
Uburambe ntibupimwa mumyaka-bupimirwa mubice byananiranye byasesenguwe. Twahinduye-injeniyeri zirenga 170 zananiranye za cobalt alloy ibice kuva muri 2019.Urugero rumwe ruragaragara: geometrike idasanzwe irananirana cyane iyo ikozwe mububiko rusange bwa Hastelloy X aho kuba ibicuruzwa-byegeranye hafi ya net. Impamvu? Imiterere y'ibinyampeke idahuye n'ibisabwa gukomera ku cyerekezo cyihuta cyo gufunga hejuru.
Niyo mpamvu inkunga yacu yo gushushanya itangirana na metallurgie-ntabwo ari geometrie. Niba winch center ya shaft roller ibonye 120 MPa yo guhangayikishwa no guhura namazi yumunyu, tuzasaba T800 hejuru ya Hastelloy C-276 isanzwe - sibyo kuko "ari byiza," ariko kubera ko ikwirakwizwa rya karbide irwanya umunaniro wubutaka kuri 85 ° C. Tuzashyira ahagaragara kandi amakimbirane ya GD&T hakiri kare: kwihanganira imyanya ku cyambu gifatanye bidashoboka gufata nyuma yo kuvura ubushyuhe? Tuzatanga inama yo guhindura gahunda ya datum-tutavuze gusa ngo "biragoye."
Intego yacu ya R&D ntabwo yibanze kumavuta mashya. Ari mubikorwa bya Hybrid: casting + precision EDM gucukura kumiyoboro ikonjesha imbere muri cobalt alloy nozzles, cyangwa lazeri yambaye lazeri kumyanda ya pompe idafite ibyuma. Ibi ntabwo ari akazi ka laboratoire. Ibi nibisubizo byateguwe neza byemejwe kuri pompe zo mu nyanja y'Amajyaruguru hamwe na skalide yo mu majyepfo y'uburasirazuba bwa Aziya.
Icyo "gukora ibicuruzwa byihariye" bisobanura mubyukuri
"Precision" bivuga raporo yawe ya CMM yerekana gutandukana kwa 0.008 mm kuri diametero 200 - byagenzuwe na Zeiss CONTURA G2, ntabwo ari kaliperi. "Custom" bivuze ko twubaka fixture, progaramu ya probe inzira, kandi tukandika inyandiko ikurikirana-ndetse no kuri prototype imwe. "Gukora" bivuga ibicuruzwa byawe byoherejwe hamwe ninyandiko eshatu: icyemezo cyibikoresho (harimo numero yubushyuhe), raporo yerekana (hamwe no gutandukanya ibara ryerekana ibara), hamwe no gusinya inzira (gukata imbaraga, gukonjesha temp, umutwaro wa spindle).
Abakiriya bisi-uhereye kubudage bwa hydraulic sisitemu ihuza abadandaza ibikoresho bya peteroli yo muri Amerika-baduhitamo kuko gutanga ntabwo ari amatariki gusa. Byerekeranye no guhanura: nta gusimbuza ibintu kumunota wanyuma, nta gitangaza NCRs, oya "tuzagenzura hamwe nabafatanyabikorwa bacu." Mugihe ukeneye Uruganda rwa Hastelloy kwizerwa, ukeneye itsinda rimwe rifite buri gihinduka. Ntabwo ari urunigi.
Sura https://www.tsingtaocnc.com gusubiramo ubushobozi bwemewe bwo gukora, gukuramo ubushakashatsi bwukuri-bwisi, cyangwa gutanga igishushanyo kubitekerezo byatanzwe-hamwe nibisubizo mumasaha 48.
