Iyo ba injeniyeri bagaragaje a uruganda rukora ibyuma kubice byingenzi byubutumwa-pompe ya pompe munsi yumubari 300, cobalt-alloy nozzles ahantu hashobora kuba gazi, cyangwa imashini ya winch kumodoka zubuhanga bwo hanze - ntibakenera gutunganya gusa. Bakeneye metallurgical sure, gusubiramo ibipimo, no kwihanganira zeru kuri microstructural drift mubice.
Twabonye imishinga myinshi yatinze-ntabwo ari inenge zishushanyije, ahubwo ni icyuho cyabatanga mugukoresha amavuta. Umukiriya yigeze kutwoherereza AMS 5387 pompe ya pompe ya cobalt ishushanya hamwe na GD&T guhamagara kuri ± 0.005 mm silindrike kuri mm 120. Abacuruzi babo babanje kubivuga - ariko ntibashobora kugoreka ubushyuhe bwo kuvura ubushyuhe buri munsi ya mm 0,02. Igice cyatsinze CMM mubushyuhe bwicyumba, cyananiwe gukora ikizamini kuri temp ikora. Ntabwo arikibazo cyo gutunganya. Nibikoresho-inzira-guhuza kunanirwa.
Impamvu ubuhanga bwibikoresho butandukanya abakora shaft neza nububiko rusange bwakazi
Amavuta ya Cobalt-nikel nka T800 na AMS 5387 ntabwo "bigoye gukora imashini" kuko aroroshye. Biragoye kuko microstructure yabo irwanya koroshya ubushyuhe-kandi uko gutuza kwabo gutuma bakunda gukora cyane, kubaka inkombe, hamwe no gutandukanya ibyiciro byo munsi y'ubutaka niba gutera igipimo cyo gukonjesha cyangwa inzitizi zo kugabanya ibibazo bitandukana na 15 ° C.
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri shitingi ya cobalt-alloy itangirana na fagitire yemewe ishobora gukurikiranwa na raporo y'ibizamini by'urusyo - ntabwo ari amanota gusa, ahubwo ibirimo karubone, boron, na silikoni muri ± 0.02%. Turafatanya kugenzura chimie yashonze hamwe nabaduha ibikoresho mbere yo gukina. Kubera iki? Kuberako 0.003% birenze boron muri AMS 5387 byongera ingaruka zishyushye mugihe cyo gushora imari 40%, kumibare ya ASTM E1268 twemeje muri 2023.
Ibi ntabwo ari theoretical. Umwaka ushize, hydraulic OEM yu Burayi yari ikeneye amazu ya mm 220 ya diametre piston pompe ya silinderi yubatswe imbere. Bisanzwe CNC ihinduranya ibimenyetso byibumoso byakwirakwije umunaniro kuri 12,000 PSI. Twahinduye uburyo bwo gutunganya imvange: ishoramari ryashizwe hafi-net imiterere + ihangayikishijwe + kurangiza-gutunganyirizwa kuri 5-axis ya horizontal itambitse hamwe nigihe nyacyo cyo kunyeganyega. Igisubizo: uburinganire bwubutaka Ra ≤0.4 µm, kwibanda kuri spline bigera kuri mm 0.008 hejuru ya mm 300 z'uburebure - nubwo nyuma yamasaha 200 yipimishije umunyu.
Guhuza Vertical ntabwo ari ijambo ryijambo-niyo nzira yonyine yo kugenzura ubunyangamugayo
Abatanga “precision shaft” benshi batanga hanze, guta ubushyuhe, cyangwa kurangiza. Ibyo bivuna kubazwa. Niba icyuma kitagira umuyonga hagati ya shaft cyananiwe kugenzura nyuma yubushyuhe-buvura, ninde ufite nyirabayazana? Uruganda? Ukoresha itanura? Umukanishi wakuyeho decarburized layer?
QINGDAO QIANGSENYUAN ikora ikigo kimwe cyujuje ISO aho gutara, imirongo myinshi CNC, kuvura ubushyuhe, no kurangiza hejuru bibera munsi yinzu imwe - hamwe na sisitemu imwe. Igiti cyose kibona:
- Kugenzura ibikoresho bito ukoresheje OES spectrometry (ntabwo ari cert gusa)
- Mubikorwa CMM igenzura mubyiciro bitatu: mbere yubushyuhe-bwo-kuvura, nyuma yubushyuhe-nyuma, kurangiza
- Igenzura ryanyuma ukoresheje optique profilometrie kubintu bifatika bifatika
- Byuzuye gukurikiranwa: gushonga ID, ibiti by'itanura, ibikoresho byo kwambara ibikoresho, indangamuntu
Ntabwo duhura gusa na ASME B16.5 cyangwa ISO 2768-mK. Dushushanya uburyo buri ntambwe igira ingaruka kumikorere yanyuma. Urugero: fondasiyo ya pompe yumucanga isaba gukonjeshwa kugenzura kugirango wirinde grafite nodule. Turakurikirana gukonjesha imirongo hamwe na thermocouples yashyizwemo - ntabwo ari ibidukikije gusa. Niyo mpamvu amazu yacu ya EN-GJS-400-15 ahora agera kuri 420 MPa imbaraga zingana, ntabwo byibuze byibuze 370 MPa.
Gutanga kwisi-bisobanura gukemura ibitari ku gishushanyo
Isosiyete ikora ibijyanye na peteroli yo muri Amerika ya ruguru yatwoherereje igishushanyo mbonera cya santere idasanzwe yo gushushanya amazi yo mu nyanja nini cyane. Nta bikoresho bifatika - gusa "birwanya ruswa, umutwaro uhagaze 150 kN." Twakoresheje uburyo bwo kwangirika kuri NACE MR0175 / ISO 15156 ibidukikije, imirongo yubuzima bwumunaniro kuri UNS S32750 na Inconel 718, tunasaba UNS S32760 hamwe na duplex anneal + kurasa. Yabakijije 28% na nikel alloy igiciro - utabangamiye kurwanya chloride SCC.
Ibi ni imyitozo isanzwe - ntabwo ari ibintu bidasanzwe. Itsinda ryacu ryubwubatsi risanzwe ryerekana ingaruka zishobora guterwa mugihe cyo gushushanya: ibice bikikijwe n'inkuta zoroshye kugoreka ibintu, kwihanganira ibintu bisaba ibikoresho bitari bisanzwe, ibikoresho bya GD&T bivuguruzanya na Cpk ishobora kugerwaho. Turasubiza ibitekerezo mumasaha 48-ntabwo "tuzabisubiramo," ariko "dore uko twabikora, kandi dore ubucuruzi bwigihe cyo kuyobora nigiciro."
Niba ukeneye a uruganda rukora ibyuma ifata imitwaro yawe ya valve inzu nkibintu biguruka-ntabwo ari igice cyibicuruzwa-urimo gushakisha disipuline yemejwe, kugenzura inzira ifunze, hamwe nubuhanga bwubuhanga buvuga metallurgie neza, GD&T, nuburyo bwo kunanirwa kumurima. Ntabwo ubushobozi bwa CNC gusa. Ntabwo ari ugutera amajwi gusa. Ubusobanuro, bushingiye ku kuri gufatika.
