Iyo ba injeniyeri bagaragaje a uruganda rwa valve, ntabwo batumiza ibice gusa-bahitamo umufatanyabikorwa ushoboye kwihanganira ± 0.01 mm kwihanganira umuvuduko wa bar, 350, gukomeza ubusugire bwa microstructural nyuma yo kuvura ubushyuhe, no gutanga ibikoresho byuzuye kugirango ASME Igice cya VIII cyangwa API 6A yubahirize. Uku nukuri kubikorwa-ntabwo imvugo yo kwamamaza.
Twabonye imishinga myinshi ihagaze kubera ko utanga "wujuje ibyangombwa" adashobora gufata umuhamagaro wa GD&T kumurongo wa cobalt-nikel valve mugihe cyo kugenzura kwa nyuma kwa CMM. Pompe imwe yo muri Amerika ya ruguru OEM yatakaje ibyumweru bitandatu mugihe umucuruzi wabo wambere yasobanuye nabi ingano yubunini bwa AMS 5387 - bikaviramo gucika imburagihe kumwanya wintebe. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata akazu ka valve yose nka sisitemu ikora: gufunga geometrike yubuso, guhuza ubushyuhe bwo guhuza ubushyuhe, no gukwirakwiza stress ntabwo ari impungenge za kabiri. Zubatswe mumashanyarazi yambere.
Ikigo cyacu cyujuje ISO muri Qingdao gikemura ibyuzuye - guta umucanga wa ASTM A48 Icyiciro cya 35 cyicyuma cyumukara wicyuma, imirongo myinshi CNC irangiza inzira yimbere yimbere, hamwe no kuvura ubushyuhe nyuma yimashini byemejwe no gushushanya amakarita hamwe nicyitegererezo. Ntabwo dushyira hanze intambwe zikomeye. Iyo uruganda rukora hydraulic rwiburayi rwakeneraga inzu ya silindiri ya mm 220 ya piston pompe ya pompe ya pompe ya pompe ya pompe ya pompe ya pompe ya pisitori ya 42CrMo4 hamwe nubutaka bwa kashe ya nitride, twagenzuye uburyo bwa metallurgjique kuva kuri bilet mbisi kugeza ku ndunduro yanyuma - nta tandukanyirizo-ry-icyiciro muburyo bwimbitse cyangwa gukomera. Uku kwishyira hamwe guhagaritse gukuraho kunanirwa kwimbere hagati yimishinga nububiko bwimashini.
Ibyemezo bitatu bya tekiniki bitandukanya umusaruro wizewe wa valve cage no gutunganya ibicuruzwa:
- Indero yo gushakisha ibikoresho: Dukoresha gusa ibivangwa na cobalt (T800, Stellite 6, AMS 5387) byemejwe na raporo y'ibizamini byo gusya hamwe no kwemeza imitungo yuzuye ya chimique na mashini - ntabwo ari amazina yicyiciro gusa kuri fagitire. Itsinda ryacu tekinike ryujuje ibisabwa abatanga isoko bakoresheje isesengura ry ingano ya ASTM E112 hamwe na ASTM E384 yipimisha mikorobe mu bice bitandukanye.
- Gahunda-yambere ya geometrie: Mbere yo gukata ibyuma, abajenjeri bacu bigana kugoreka ubushyuhe mugihe cyinshyi zigabanya ibibazo kumazu manini. Kuburyo bwa offshore winch center shaft roller order, twahinduye inzira igoye kugirango twishyure mm 0.018 mm yahanuwe - dukuraho imirimo yatinda gutanga iminsi 11.
- Ubugenzuzi bwashyizwemo - ntabwo bwongeweho: Akazu kose ka valve gakorerwa ubugenzuzi butatu bwa CMM: nyuma yo gutunganya nabi (kugenzura amafaranga yimigabane), nyuma yo gutunganya imashini (GD&T yuzuye), na nyuma yo gukora isuku rya nyuma (kugirango umenye ibyangiritse). Optical profilometry igenzura ikidodo hejuru Ra agaciro kamanuka kuri 0.2 µm - yagenzuwe ukurikije ibipimo ngenderwaho byabakiriya, ntabwo ari rusange.
Bamwe batekereza ko cobalt alloy valve cage ikenera ibikoresho bidasanzwe. Ukuri nukuri, intsinzi ishingiye kubisubiramo - ntabwo ari shyashya. Dukoresha ibikoresho bimwe bisa mumashini atanu ya HAAS VF-6 ya AMS 5387 nozzles, hamwe no kugenzura imitwaro ya spindle hamwe nibikoresho byikora byangiritse. Iyo serivise y’ibikomoka kuri peteroli yo mu majyepfo y’iburasirazuba bwa Aziya yategetse ibyuma 47 bya cobalt alloy plaque ifite imyanya 12 ° ya conic, twageze ku musaruro wa 99.4% byambere-biturutse kuri "AI yateye imbere," ariko kubera ko abadukoresha badasubiramo inama za probe buri masaha 8 hanyuma bakanashyira ingufu za pH kuri buri mwanya.
Igiciro ntigabanywa mugukata inguni. Igenzurwa no gukuraho gushidikanya. Isuzuma ryubuhanga ryacu ririmo ibitekerezo byakozwe mugihe cyamasaha 48: kumanika ibice bikikijwe n'inkuta zoroshye kuganira, byerekana ubundi buryo bwa radiyo kugirango wirinde ibimenyetso bya EDM, cyangwa gusaba impinduka zikurikirana kugirango hirindwe intambara muri geometrike idasanzwe. Umukiriya umwe yagabanije igiciro cyose cyumushinga 22% nyuma yo gusaba ko twava mubushoramari T800 tukajya kumucanga + utunganijwe neza-17-4PH - utabangamiye igipimo cy’igitutu.
A uruganda rwa valve yizera ikizere iyo yohereje inyandiko hamwe na buri gice: ibikoresho byerekana ibikoresho, inyandiko zivura ubushyuhe, raporo ya CMM hamwe no gutandukana gutondekanye, hamwe namafoto yo kugenzura yerekana kwerekana kurangiza neza. Turabikora kuri buri gahunda - ndetse na prototypes. Kuberako muri hydraulics yumuvuduko mwinshi cyangwa sisitemu yo kugenzura inyanja, akazu ntikigize. Numupaka hagati yimikorere no gutsindwa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikomeje kunonosora uburyo bwo kuvanga-gutunganya imashini izakurikiraho-pompe ya pompe-cyane cyane yibanda kuri coefficient ihamye (<± 1.5%) hamwe nigihe kinini cya serivisi mubuzima bubi. Intego ntigihinduka: kora ituze ryurwego ruteganijwe, imikorere ya metallurgjique igenzurwa, nigihe cyo gutanga ntigishobora kuganirwaho.
