Urabona 'Stellite' yajugunywe hafi muri valve igaragara, cyane cyane kumipira n'intebe. Ibitekerezo byihuse ni ibintu bikomeye cyane, birwanya kwambara urikubita, kandi bigatera imbere - ikibazo cyakemutse. Aho niho ibibazo byinshi bitangirira. Mubyukuri, kwerekana a Umupira wa valve umupira nintebe ntabwo ari icyemezo kimwe; ni urukurikirane rwamahitamo ahujwe kubyerekeranye na substrate, uburyo bwo gusaba, icyiciro cyihariye cya Satelite, hamwe no gutunganya bwa nyuma. Fata kimwe kibi, kandi inteko yose irashobora kudakora neza cyangwa kunanirwa imburagihe, ihindure ishoramari ryambere mumasomo ahenze.
Ibitekerezo Byibanze: Byose Kubikomeye
Impapuro nyinshi zitanga amasoko zishimangira gukomera, mubisanzwe bisaba ikintu nka HRC 40-45 byibuze kuri Stellite 6 hejuru. Mugihe gukomera ari ingenzi kubirwanya abrasion, ni igice cyinkuru. Nabonye intebe zujuje ubuziranenge ariko zacitse muri serivisi kubera ko ibikoresho byibanze, tuvuge ko 13Cr martensitike idafite umwanda, ntabwo byateguwe neza cyangwa icyogajuru cyashyizwemo umubyimba mwinshi nta kugabanya ububabare bukwiye. Inkwano yananiwe. Guhangayikishwa numubare birengagiza guhuza metallurgical hamwe nibisigisigi bisigaye byo gusudira cyangwa gutera.
Noneho hariho substrate. Ntushobora gukoresha icyogajuru kubintu byose. Kumupira, ukunze kureba 17-4PH cyangwa 316SS. Ku ntebe, irashobora kwinjizwa muri 410 cyangwa Inconel 718. Coefficient yo kwagura ubushyuhe igomba kuba mumupira umwe. Ndibuka umushinga wumuvuduko mwinshi wo kureka valve aho impeta yintebe yari 316L, hanyuma tugashyiraho igicucu cya Stellite 21. Mugihe cyamagare yubushyuhe, kwaguka gutandukanye kwatumye umusatsi ucika imbere. Igice cyatsinze QA gukomera no gusiga irangi, ariko byananiye mumurima nyuma yizunguruka nke. Intandaro? Guhitamo substrate kuri iyo nshingano yihariye yubushyuhe byari bibi.
Igikorwa cyo gusaba ubwacyo ni ikirombe. Gusudira PTA (Plasma Transferred Arc) birasanzwe kandi bitanga umurunga mwiza, wuzuye, ariko ubushyuhe bwinjiza ni ngombwa. Kwambika lazeri birasobanutse neza hamwe nubushyuhe buke, ariko igiciro kinini ni kinini kandi ifu ya morphologie igomba kuba nziza. Gusudira Oxy-acetylene, uburyo bwa kera-bwishuri, buracyari hanze kugirango busanwe; itanga ibyiza, byoroshye-ish kubitsa ariko ni ubuhanga-bushingiye cyane. Buri buryo butanga microstructure itandukanye, igipimo cyo kugabanuka hamwe nicyuma fatizo, hamwe nuburyo bwa nyuma bwo guhangayika. Kugaragaza icyogajuru cyuzuye udasobanuye inzira ni ubutumire bwo guhinduka.
Guhitamo amanota: Icyogajuru 6, 12, 21, cyangwa Ikindi?
Stellite 6 nifarashi yakazi, kwangirika muri rusange no kwihanganira kwambara. Ariko ntabwo buri gihe ari igisubizo. Muri serivisi zangiza cyane, zumucanga zumucanga, Stellite 12, hamwe nibirimo byinshi bya karubone kuri karbide nyinshi, birashobora gufata neza. Ariko, ubwo bukomere bwiyongereye buzanwa no kugabanuka kwingaruka. Kuri serivisi zifite cavitation zikomeye, nko muri pompe zisohora pompe, zikaze, zifite imbaraga nyinshi Stellite 21 irashobora rimwe na rimwe gukurura micro-ingaruka nziza nta gucika mikoro.
Aha niho gufatanya nu ruganda rukora imashini zumva ibintu byuzuye byubuzima. Isosiyete nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), hamwe nimyaka mirongo itatu mugukina no gutunganya, mubisanzwe ibona ibi. Ntabwo ari abatumiza gusa; uburambe bwabo mubikonoshwa no gushora imari, wongeyeho akazi kabo hamwe na cobalt na nikel alloys, bivuze ko babona igice kuva mubyuma bishongeshejwe kugeza kurwego rwuzuye. Nibo bagomba kwibaza niba Stellite 6 PTA yuzuye hejuru yumupira-shoramari 17-4PH numuhamagaro ukwiye wa serivise yihariye ya gazi, byerekana wenda protocole itandukanye mbere yubushyuhe cyangwa se guhinduranya uburyo bwa nikel bushingiye kuri nikel nka Colmonoy kugirango birusheho guhangana na sulfide.
Shitani iri murwego rwo kuvura ubushyuhe no gutunganya. Nyuma yo kwambara, kugabanya imihangayiko ntabwo biganirwaho. Gukora ubuso bwambaye kugeza kwihanganira bwa nyuma, cyane cyane hejuru yumupira wamaguru cyangwa impande zifunganye, ni ubuhanga bwihariye. Ukeneye CNC gushiraho birakomeye bihagije kugirango ukemure igihe gito hamwe nibikoresho bishobora gucunga imiterere ikomeye, gummy ya Stellite idakomereye akazi. Intebe idakozwe neza izaba ifite amarira-mikoro ahinduka intangiriro yo gutwarwa nisuri. Nabwirijwe kwanga ibice bisa neza neza na CMM ariko numvaga ndakaye mugihe wakoreshaga urutoki hejuru yikimenyetso - ikimenyetso cyerekana ibintu byacitse bivuye mubikoresho bituje.
Imyifatire-Isi Yose hamwe ninama zinteko
Ndetse nibice byuzuye, inteko irashobora kwica imikorere. Ikosa rya kera ni ukurenza urugero kugumana intebe. Ufite iyi mashini nziza ya Stellite yicaye ikanda cyangwa yomekwa mumubiri munini. Niba igikwiye ari gito cyane cyangwa torque ndende cyane, urashobora kugoreka impeta yintebe, ugakora bore idafite uruziga. Umupira uzahita ufunga gusa ahantu hirengeye, biganisha kumyambarire yihuse kandi isohoka. Ibi nabyize inzira igoye kumurongo wa trunnion-yashizwe kumupira. Twirukanye ibyumweru byinshi, dusimbuza imipira n'intebe, mbere yuko amaherezo tugenzura bore geometrie yumufuka wintebe mumubiri - yari oval na kimwe cya cumi nyuma yo guterana.
Indi ngingo ififitse ni ukumena cyangwa gukubita. Bamwe mu bakora isuku bashimangira ko imipira yintebe nintebe bigomba gufatanwa byoroheje nkurwego rumwe. Abandi bavuga ko hamwe no gutunganya CNC igezweho, bagomba gufunga neza mu gasanduku. Icyo mfata nuko biterwa nurwego rwo gushiraho ikimenyetso. Kuri ANSI Icyiciro cya VI (bubble-tight) intebe yoroshye, ntaho bihuriye. Kubyicaro byicyuma, Icyiciro cya IV cyangwa V, urumuri rwinshi, rugenzurwa hamwe nuruvange rwiza rushobora gufasha muguhuza microscopique ingingo ndende. Ariko birenze urugero, kandi wangiza geometrie nubuso burangije. Nibintu bikoraho, ntabwo ari inzira ushobora kwandika byoroshye.
Agaciro ko Gukora Byuzuye
Niyo mpamvu itandukaniro riri hagati yububiko bwakazi bworoshye nuwabikoze ahuriweho ni ngombwa. Iyo gukina, kwambika, kuvura ubushyuhe, no gutunganya neza biri munsi yinzu, cyangwa byibuze bihujwe neza, wirinda gutunga urutoki. Niba hari inenge muri substrate casting igaragara gusa nyuma yo kwambika, isoko imwe itanga isoko ifite ikibazo. Bashobora gukurikirana amateka yubushyuhe bwigice kuva mbere.
Urebye kubitanga nka QSY (https://www.tsingtaocnc.com). Kuri a Umupira w'amaguru, barashobora gushora imari batera umupira kumurongo hafi ya net kuva muburyo buboneye, gukora PTA yambaye murugo, bagakora ubushyuhe bukenewe nyuma yo gusudira, hanyuma bakarangiza imashini hejuru yumubumbe no guhuza uruti kumisarani ya CNC hamwe nibikoresho bizima. Ukwo gukomeza kugenzura impinduka. Injeniyeri ngaho yari kumenya neza umubare wibigega byo gusiga kuri casting ya layer yambaye, uko igice kigoreka mugihe cyo gusudira, nuburyo bwo kugihuza kugirango imashini yanyuma ifate icya cumi.
Ubundi buryo ni urwego rwacitsemo ibice: Isosiyete A itera ubusa, Isosiyete B ikora clading, Isosiyete C ikora ubushyuhe, Isosiyete D ikora imashini. Buri ntambwe yongeramo ibikoresho, kongera guhuza amakosa, kandi, akaga gakomeye, gukwirakwiza inshingano. Iyo intebe irangiye yananiwe kwipimisha helium, abantu bose bashinja undi musore. Uburyo bukomatanyirijwe ntibushobora guhora buhendutse kuri cote yambere, ariko bigabanya cyane igiciro cyose cyubwiza nibibazo.
Kurangiza Ibitekerezo: Ni Sisitemu, Ntabwo ari Coating
Noneho, mugihe ukurikira usubiramo ingingo ya a Intebe ya satelite n'umupira, reba ibirenze guhamagarwa. Tekereza kuri gahunda. Ni ubuhe buryo bwuzuye bwimiti nubukanishi? Substrate ni iki, kandi irahuye? Nigute icyogajuru gikoreshwa kandi kirangiye? Ni gute ibice bizateranyirizwa hamwe? Nta myitozo myiza yisi yose, gusa ibyingenzi bikwiye byo kumvikana kuri serivisi.
Intego ntabwo ari ukugira gusa icyogajuru. Intego ni ukugira igisubizo cyizewe, kirambye. Rimwe na rimwe, ibyo bishobora no gusobanura kubaza ikibazo - muri serivisi zimwe na zimwe zifite umuvuduko muke, serivisi zisukuye, 440C ikomye cyangwa nitride ivurwa na 17-4PH irashobora gukora akazi ku giciro gito. Ariko mugihe ukeneye ubwo buvanganzo bwo kurwanya galling, kurwanya ruswa, hamwe no kurwanya isuri itanga cobalt alloys idasanzwe, noneho wiyemeje gukora injeniyeri yibice byose hamwe no gusobanukirwa. Ntabwo ari kugura ibicuruzwa; ni ubufatanye bwa tekiniki hagati yuwashushanyije nuwabikoze yanduza amaboko inzira. Aho niho hubakwa kwizerwa nyako.
