Uruganda rukora ibyuma byamazi - iyi nteruro itera ibibazo byihuse kubajenjeri bashakisha ibice byuzuye-byuzuye: Birashoboka kubyara umusaruro uri hejuru ya 10,000? Irashobora kwihanganira ± 0,02 mm kwihanganira umubiri wa cobalt alloy valve? Irakuraho micro-porosity yibasira abashoramari basanzwe munsi ya 350? Twabajije ibi bibazo nyabyo kubashinzwe sisitemu ya hydraulic muri Milwaukee, kuvoma OEM muri Stuttgart, hamwe n’ibikoresho bikoresha peteroli muri Singapuru - isuzuma ry’imishinga irenga 247 kuva 2021. Igisubizo ntabwo "yego, niba ibintu bimeze neza." Ni “yego -niba uruganda rwawe rwamazi rutera inshinge rukora nkububiko butunganya neza, nubwa kabiri. ”
Kuki Uruganda rwa LMIM rwananiwe kurwego rwo hejuru (kandi niki gikora)
Abatanga ibicuruzwa benshi bafata ibyuma byatewe inshinge nkibikoresho byo guta - gusuka ibishishwa bishongeshejwe mubibumbano, bikonje, bihinda umushyitsi, birangire. Iyo moderi irananirana mugihe ukeneye AMS 5387 cobalt alloy nozzles irokoka 12,000 yumuriro utarinze gukwirakwizwa na microcrack. Ibi twabyize inzira igoye mugihe cya 2022 cyindege ya pompe yinyanja yo mumajyaruguru: ubukana bwubutaka bwakubise Ra 3.2 µm, ariko ingano yubutaka bwo munsi ntiyari ihuye nibyiciro. Impamvu? Igenzura rya Thermal gradient mugihe cyo gukomera ntiryari rihujwe na CNC yakozwe na die geometrie cyangwa kugenzura igihe nyacyo cyo gushonga.
Ukuri kwukuri LMIM isaba ibice bitatu bitaganirwaho:
- Gupima urwego.
- Gushonga ubwenge.<0.5 ppm) kuri T800 ishingiye ku mavuta, yagenzuwe kuri ASTM E1479
- Kwemeza ibipimo byuzuye: Ubufindo bwose bukorerwa ubugenzuzi bwa CMM kuri 12 datum mbere yo kuvura ubushyuhe - ntabwo ari "as-cast" gusa
Niyo mpamvu ikigo cyacu muri Qingdao kidatandukanya amashami ya "casting" na "mashini". Inzu ya piston pompe inzu yinjira nka prefegitura ya LMIM; gusohoka nkigice cyuzuye - hamwe na GD&T guhamagarwa byemejwe na ISO 2768-mK, ntabwo ari "gucapa."
Aho Amazi yo Gutera Amazi Yububiko Bwububiko Bwuzuye Imizigo Yinganda
Baza umuyobozi ushinzwe amasoko ukoresha sisitemu yo gutwara ibinyabiziga: “Ni iki kibanza?” Ntabwo ari moteri. Ntabwo ari garebox. Ni uruziga rwagati rwagati-rushingiye ku guhinduranya imitwaro ya torsion igera kuri 42 kN · m mugihe yashyizwemo nabi. Umusenyi usanzwe utera umunaniro kuri 8000 cycle. LMIM + yacu nyuma yimpimbano ya T800 irenga 210.000 mukuzenguruka mugice cya gatatu SAE J2570. Nigute? Kuberako dushyira kuri 1,380 ° C hamwe na 0.8-isegonda yo kuzuza, hanyuma dushyireho ingufu zo gukomera (120 MPa) zihujwe no gupfa ikarita yubushyuhe. Nta gukeka. Nta “ibipimo ngenderwaho bisanzwe.”
Turabona ibintu bitatu bihoraho byo gukoresha aho LMIM itanga ROI munzira gakondo:
- Umuvuduko wumuvuduko hamwe ninzira zuzuye: Kurandura ingingo 3-5 zikunda gusudira; ikomeza intebe ya 0,015 mm nyuma yamasaha 500 kuri 415 ° C.
- Urufatiro rwa pompe rusaba guhindagurika: Imiterere ya LMIM nziza ya dendritic igabanya resonant frequency ihindagurika kuri 37% hamwe na gravit-cast ihwanye
- Amashanyarazi adasanzwe ya cobalt yamashanyarazi kubikoresho byo hasi: Kugera kuri 62 HRC yubuso butarinze gukarubura-byingenzi kugirango API RP 16A yubahirizwe
Nta na kimwe muri ibyo gikora kidafite ibikoresho fatizo bikurikiranwa. Buri fagitire ya AMS 5387 itwara raporo yikizamini cyo gusya, ibiti byo gusesengura ibintu, hamwe na dosiye yihariye yamateka yubushyuhe - ntabwo ari numero yicyemezo.
Ibyo Ugura Mubyukuri (Kurenga Igice)
Uruganda rutunganya ibyuma byamazi ntabwo rugurisha. Nukwagura inzira yawe. Iyo pompe yu Burayi OEM yatwoherereje igishushanyo cya GD & T-kiremereye cyo guterana kwa orifice nozzle, ikipe yacu ntabwo yavuze gusa. Twakoresheje inshuro esheshatu zo kwigana ubushyuhe bwumuriro-dushira ahabona amakimbirane abiri ya datum yerekana amakimbirane yaba yarateje mm 0,04 munteko yanyuma. Twasabye kwimura datum imwe hejuru yimashini ya flange aho kuba umuyobozi wa cast. Igisubizo: ingingo ya mbere igipimo cyatsinze cyavuye kuri 63% kigera kuri 98%.
Uru rwego rwo gusezerana rusaba guhuza vertical: casting, CNC, kuvura ubushyuhe, na NDT byose munsi yinzu imwe yemewe ISO 9001: 2015. Nta ntoki. Nta cyuho kiboneka. Gusa inyandiko zerekana ubugenzuzi-buri ntambwe ikurikiranwa nindangamuntu, nimero yimashini, hamwe namakuru y’ibidukikije.
Ijambo ryanyuma: Icyitonderwa ntabwo ari ugushiraho. Ni Urukurikirane.
Niba porogaramu yawe isaba imikorere isubirwamo mugihe cyumuvuduko ukabije, ubushyuhe, cyangwa kwambara - noneho uruganda rwawe rutera inshinge rugomba kwerekana ubushobozi mubice bitatu: kugenzura ibyuma, kugenzura geometrike, hamwe nubufatanye bwubuhanga. Twubatse ibikorwa byacu hafi yizo nkingi - ntabwo ari byiza, ahubwo nkibigenzurwa buri munsi. Kumuvuduko wumuvuduko ufashe akabari 350, kubiti bya winch bizunguruka mucyondo cya Arctique, kuri nozzles zipima ibintu byangirika byangirika: ibisobanuro ntabwo byumvikanyweho. Yakozwe muri garama yicyuma, buri micron yo kwihanganira, buri saha yo kwiyemeza gutanga.
