Ukubunjwa kwesanti kuseyinqubo esetshenziswa kakhulu yokwenza insimbi—okuhlanganisa ngaphezu kwama-70% akho konke ukulingisa okukhiqizwa emhlabeni jikelele. Kodwa kwabasanda kufika abangena endaweni yokusungula, inani eliphelele le izingxenye zokuphonsa isihlabathi angazizwa ekhungathekile. Amaphethini, ukubhekana nokuhudula, ama-sprues, izikhuphukeli, ama-cores, amasango-ngalinye lidlala indima engenakuxoxiswa ukuthi ngabe ukulingwa kuphuma kunomsindo noma i-scrap.
Sibone inqwaba yonjiniyela besikhathi sokuqala behambisa kabi umugqa wokuhlukanisa ngesikhathi sokuhlanganiswa kwesikhunta. Sike sabuka ochwepheshe abanolwazi bengakunaki ukubekwa kwe-vent-futhi bagcina sebenamaphakethe egesi emizimbeni yamavalvu asebenza ngogesi. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., lapho sikhiqiza khona insimbi enembayo nensimbi yezindlu zepompo ezinomfutho ophezulu kanye nemibhobho ye-cobalt-alloy, yonke ingxenye yesikhunta sesihlabathi iyaqinisekiswa—akucatshangwa. Ake sihlukanise okubalulekile izingxenye zokuphonsa isihlabathi, hhayi njengezincazelo zezincwadi zokufunda, kodwa njengezinto ezisebenzayo esithembele kuzo nsuku zonke ukuletha izingxenye ezibamba ukucindezela kwebha okungu-350+ ngaphandle kokuvuza.
Izingxenye Eziyinhloko Okufanele Uziqonde Ngaphambi Kokuthela
Isikhunta sokuphonsa isihlabathi akusona nje isihlabathi esigcwele. Iwuhlelo oluklanywe ngokunembile oluklanyelwe ukulawula ukugeleza kwensimbi, ukuqinisa okuphakelayo, nokukhulula amagesi avaleleke. Nazi izingxenye zomzimba ezinhlanu okungaxoxiswana ngazo-futhi kwenzekani uma noma yimuphi ehluleka:
- Iphethini: Ikhophi yosayizi ogcwele yengxenye yokugcina—imvamisa eyenziwe ngokhuni, ipulasitiki, noma i-aluminium eyenziwe ngomshini. Ukunemba kwayo kuchaza ngokuqondile ukubekezelelana kwe-dimensional. Sisebenzisa amaphethini e-aluminium enziwe ngomshini we-CNC ezindlini zamasilinda ngoba abamba ±0.15 mm ubude obungu-400 mm—okubalulekile uma kwenziwa ngomshini izindawo zokuvala ngemva kokusakazwa.
- Khomba futhi uhudule: Ingxenye yesikhunta engaphezulu (ukubhekana) nephansi (hudula). I-interface yabo iwumugqa wokuhlukanisa. Ukungaqondani kahle lapha kudala ifleshi okufanele icishwe—isinyathelo esibizayo sokuphinda sisebenze esisigwemayo ngokusebenzisa ukubhaliswa kwephinikhodi kukho konke ukubunjwa kokukhiqiza.
- Sprue: Ishaneli eqondile lapho insimbi encibilikisiwe ingena khona emgodini wesikhunta. Incane kakhulu? I-turbulence inyusa ukwakheka kwe-oxide. Ibanzi kakhulu? Ukondla okungalungile. Ezingxenyeni zethu zepompo ye-cobalt alloy ye-T800, sisayizi we-sprues ngokusekelwe ezibalweni zekhanda le-metallostatic—hhayi amashadi omthetho wesithupha.
- Riser: Indawo yokugcina amanzi ebekwe ngenhla noma eceleni kokusakaza ukuze kunciphe ukuncipha ngesikhathi sokuqina. Iphutha elivamile: ukwehlisa usayizi wezikhuphukeli zezingxenye eziwugqinsi. Eqeqebeni elilodwa lezindlu ze-piston pump cylinder, ivolumu yesikhuphukeli enganele yabangela i-centerline porosity-itholwe kuphela ngesikhathi sokuhlolwa kwe-ultrasonic. Manje silingisa ukuqina nge-MAGMAsoft ngaphambi kokwenziwa kwesikhunta.
- Ingqikithi: Indawo ehlukile yesihlabathi eyenza imigodi yangaphakathi—njengamaphasishi apholile noma amabhobho amavalvu. Ama-cores kumele amelane nengcindezi ye-metallostatic kanye nokushaqeka kwe-thermal. Sisebenzisa isihlabathi se-silica esiboshwe ngamakhemikhali esine-furan resin ukuze siqine, bese sibhaka ku-220 ° C imizuzu engu-90. Ama-cores angabhakiwe awela ngaphansi kuka-1,450°C insimbi encibilikisiwe.
Kungani Umklamo Wesango Uhlukanisa Ukusakaza Okunokwethenjelwa Ku-Scrap
Amasango—amashaneli axhuma i-sprue kuya emgodini—awavamile ukuxoxwa ngawo, kodwa anquma ubuqotho obungaphezulu, ukwakheka kokusanhlamvu, kanye nokusatshalaliswa kokufakwa. Abanye bangase baphikise ukuthi indawo yesango ingeyesibili kumklamo wephethini. Kodwa-ke, kokuhlangenwe nakho kwethu nge-AMS 5387 cobalt alloy 6 components, ukungena kwesango okungafanele kubangela ukwehluleka okuphindaphindiwe okuthathu: ukuvala okubandayo eduze kwezindonga ezincane, ukuguguleka kwesihlabathi ezindaweni ezinesivinini esikhulu, kanye nokungena kubi ezindaweni zokungena emgodini.
Sisebenzisa isango elingaphansi ezindlini ezinde, ezinezindonga ezincane ukuze sinciphise isiyaluyalu. Ezingxenyeni ezilinganayo njengamarola e-winch center shaft, sisebenzisa amasango e-radial amaningi-ukuqinisekisa ukugcwaliswa okufanayo kanye nokuqina okuqondile kuya ezikhuphukeni. Isango ngalinye eliphambanayo libalwa kusetshenziswa umgomo kaBernoulli olungiselwe i-viscosity yensimbi nokwehla kwezinga lokushisa. Lokho akuwona umbono—indlela esifinyelela ngayo i-Cpk >1.33 kumadayimitha abalulekile kuwo wonke ama-run okukhiqiza angu-500+.
Lokho Abaqalayo Abakunakiyo: Ama-Vents, Isihlabathi sokuhlukanisa, kanye nesikhathi se-Shakeout
Izimbobo ziyizimbobo ezincane—ngokuvamile zingu-1–2 mm ububanzi—zibhobozwe endaweni noma lapho zihudulwa ukuze kuphume umoya namagesi esikhunta. Yeqa, futhi uthola ama-pinholes noma ama-blowholes. Sibhola ama-vents mathupha ngemuva kokuhlanganiswa kwesikhunta, siwabeke ezindaweni zokugcina ukugcwalisa ezikhonjwe ekufanisweni. Akukho okuzenzakalelayo-ngoba ukugqokwa kwamathuluzi kushintsha i-geometry yembobo, futhi ukungahambisani nokukhipha umoya kulimaza i-microstructure.
Isihlabathi esihlukanisayo—ungqimba olucolekile olufakwe uthuli phakathi kwe-cope and drag—kumele somile, sigeleze ngokukhululekile, futhi singahlanganisi. Sisebenzisa i-alumina powder e-calcined, hhayi i-graphite. I-graphite ifaka umswakama kusixhumi esibonakalayo sesikhunta futhi ikhuthaze amaphutha emithanjeni ekubunjweni kwensimbi engagqwali.
Isikhathi se-Shakeout sibaluleke kakhulu kunalokho abaningi abakucabangayo. Ukususa ukulingwa kusenesikhathi kudala ukuqhekeka kokushaqeka okushisayo—ikakhulukazi ku-iron enekhabhoni ephezulu. Sekwephuze kakhulu, nokushisa okuyinsalela kudala ukuhlanekezela ezindaweni eziyisithenjwa zomshini. Izinga lethu: ukusakaza okupholile komoya kuze kube yilapho izinga lokushisa lehla ngaphansi kuka-150°C, liqinisekiswa ngamathemometha aphathwayo e-IR—hhayi izibali-sikhathi.
Ukusuka Isikhunta ukuya ku-Mission-Ingxenye Ebalulekile: Lapho Ukusakaza Kwesihlabathi Kufanelana Khona Namuhla
Ukulingisa isihlabathi akubona ubuchwepheshe befa—kuyisisekelo sokukhiqiza okuxubile. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY, sihlanganisa izikhala ze-sand-cast ngomshini we-CNC onama-axis amaningi, ukwelapha ukushisa, nokuqedwa kwendawo—konke ngaphansi kophahla olulodwa oluthobela i-ISO. Lokho kulawula okuqondile kusivumela ukuthi siqinisekise ukuthobela kwe-GD&T ezicini ezifana nokugxila kwe-bore-to-flange (±0.05 mm) noma ubulukhuni obuphezulu u-Ra ≤0.8 µm ebusweni obuvaliwe.
Uma ucacisa i-valve yendlu yokucindezela noma ingxenye yewintshi yemoto yobunjiniyela, qonda ukuthi izingxenye zokuphonsa isihlabathi kusho ukwazi ukuthi ukubekezelelana kunqwabelana kuphi, ukuthi ukukhubazeka kuvela kuphi, nokuthi ukukhetha komklamo kuzithinta kanjani izindleko nesikhathi sokuhola. Kusho ukubuza ukuthi "Ingabe ingaphonswa?" kodwa “Ingxenye yesikhunta ngayinye izosebenza kanjani ku-1,520°C ngesikhathi sokuthululwa kwemizuzwana engu-12?”
Lowo umehluko phakathi komdwebo kanye nokulethwa. Futhi yingakho amakhasimende ethu—kusuka eNyakatho Melika kuya eNingizimu-mpumalanga ye-Asia—sithumelela imidwebo ecebile ye-GD&T enemininingwane eqinile yensimbi, hhayi nje imidwebo. Ngoba bayazi ukuthi isikhunta akuyona nje isitsha. Yisigaba sokuqala sokulawulwa kwekhwalithi.
