Ha pompo ea hydraulic e hlōleha tlas'a khatello ea 350-bar, molato hase hangata e leng ntlo kapa tiiso-ke eona Stellite plug. Eseng plug efe kapa efe. E 'ngoe e nang le concentricity e nepahetseng ea 0.005 mm, matrix ea cobalt e lumellanang le AMS 5387, le mapetsong a zero ka mor'a phekolo ea mocheso. Ke ka lebaka leo baenjiniere ba Houston, Hamburg le Singapore ba sa batleng "li-plug tsa cobalt alloy." Ba batla a Fektheri ea plug ea Stellite e tsamaisang likarolo—eseng litšepiso.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. e fane ka likarolo tseo ho tloha ka 2012. Ha e tsoe lethathamong la libuka. Ho tsoa tlhahlobong ea ho hloleha ha lefatše la 'nete: li-nozzles tse phatlohileng lipompong tsa ente ea kantle ho naha, lirolara tsa winch center shaft ka likoloing tsa boenjiniere tsa Arctic-grade, ho roala pele ho nako ka matlong a lisilindara tsa pompo ea piston e phahameng. Re bone mokhoa o mong le o mong oa ho hloleha — kahoo re kenya plug e 'ngoe le e' ngoe ea Stellite ho li felisa pele li qala.
Mona ke se arolang plug e sebetsang ho tloha ho e nkang 3 × nako e telele tšebeletsong: taolo ea metallurgical, eseng feela ho nepahala ha machining. T800 e thehiloeng ho Cobalt le AMS 5387 ha "li thata ho e sebelisa" - "ha li tšoarele * ha u ka ahlola hampe katoloso ea mocheso nakong ea ho fetola kapa ho tlola tharollo pele u sila. Setsing sa rona se netefalitsoeng sa ISO se Qingdao, polaka e 'ngoe le e 'ngoe ea Stellite e qala ka thepa e tala e lateloang, e netefalitsoeng - ha ho na litifikeiti tsa leloala tse amoheloang ntle le netefatso ea spectral. Re tsamaisa thepa e kenang ka tlhahlobo ea OES, ebe re fa sebaka se seng le se seng sa mocheso ID e ikhethang e kentsoeng tsamaisong ea rona ea ERP. Haeba moreki a tlaleha phoso ho Lota #QS-24-8817, re hula lirekoto tsa ts'ebetso e felletseng: sebopeho sa lijo-thollo, lits'oants'o tsa lisebelisoa tsa CNC, tlhaiso-leseling ea CMM libakeng tsa tlhahlobo ea 32, ho hlaka holimo (Ra ≤ 0.4 µm), le boima ba kalafo ka mor'a mocheso (42-48 HRC libakeng tse tharo tse netefalitsoeng). Ha ho na khakanyo. Ha ho karolelano ea palo.
Ba bang ba ka 'na ba pheha khang ea hore likarolo tsa Stellite tse ka ntle ho sethala li theko e tlaase. Empa litšenyehelo ha li baloe ka tatellano ea theko - e lekantsoe ka nako ea ho theoha. Polaka ea $210 e hlolehang ka mor'a lipotoloho tse 4,200 e bitsa chelete e fetang $390 plug e lekantsoeng ka li-cycle tse 14,500 ha rig ea hau e kantle ho naha e lahleheloa ke lihora tse 18 tsa nako ea ente. Ho hobe le ho feta: barekisi ba mefuta e meng hangata ba nkela Stellite 6 sebaka ka metsoako e theko e tlaase ea cobalt-nickel e haelloang ke phallo ea chromium carbide e hlokahalang bakeng sa tikoloho e hlephileng ea seretse. Ha re nke sebaka. Rea leka. Plaka e 'ngoe le e' ngoe e etsa liteko tsa ho fafatsa letsoai (ASTM B117, lihora tse 500), khatello ea bopaki ba hydraulic (1.5 × khatello ea ho sebetsa, e tšoaretsoeng metsotso e 10), le tlhahlobo ea ultrasonic ka ASTM E114. Haeba e sa fete ka boraro ba eona, e lahliloe-ha e sa tsosolosoa.
Re boetse re rarolla seo lifeme tse ngata li hanang ho se lumela: meeli ea geometry. Li-plug tse tloaelehileng tsa Stellite li nka mefuta e bonolo ea cylindrical. Lisebelisoa tsa 'nete li hloka li-eccentric bores, mahetla a koalang asymmetric, kapa li-grooves tse kopaneng tse pholileng tse entsoeng ka mokhoa o ts'oanang. Litsi tsa rona tsa 5-axis milling li sebetsana le li-contours tse ka hlokang litlhophiso tse tharo kae-kae—ho fokotsa liphoso tse ntseng li eketseha le ho felisa khopamiso ea ho lokisa bocha. Bakeng sa pompo e le 'ngoe ea Europe ea OEM, re ntlafalitse polaka ea Stellite e nang le mahlakore a mabeli e nang le litselana tsa ho phalla le botenya ba 0.012 mm pakeng tsa likou. Morekisi oa mantlha o qotsitse libeke tse 14 mme a hana ho ikarabella bakeng sa ho phatloha ha mokhathala. Re ile ra fana ka libeke tsa 6-ka tiiso ea strain gauge e bontšang 22% khatello e tlaase ea khatello ea kelello mateanong. Joang? Hobane sehlopha sa rona se kenyelletsa baenjiniere ba mehleng ba meralo ea pompo ba fetotseng mefokolo ea boenjineri sebakeng sa marang-rang — eseng feela ho bala li-callout tsa GD&T.
A Fektheri ea plug ea Stellite ha e hlalosoe ke libopi tsa eona kapa tshilo. E hlalosoa ka tsela eo e arabang lipotso tse tharo ka eona: Ho etsahala’ng ha thepa e futhumala nakong ea ho siloa ha ho qetela? Moeli o fokolang oa lijo-thollo o hokae ha o bapisoa le sefahleho se tiisitsoeng? Mme-haholo-holo - mosebelisi oa ho qetela o lekanya eng tšimong? Re araba tse tharo pele re khaola chip ea pele. Ke ka lebaka leo li-plug tsa rona li kenang ka har'a li-valve tsa taolo ea maoatle tse lekantsoeng ho 10,000 psi, litsamaiso tsa ente ea mafura a khatello e phahameng ka har'a literaka tse hulang merafo, le lipompo tsa dosing tse nepahetseng tse sebetsanang le li-polymer slurries tse hlabang. Eseng hobane ba kopana le li-specs — empa hobane ba pholoha maemo a itseng ha a koahele.
Ha re shebile pele, re ntse re holisa bokhoni ba rona ba ts'ebetso ea hybrid casting-machining bakeng sa likopano tse khōloanyane tsa Stellite-joaloka 'mele oa li-valve tsa monolithic tse nang le litulo tse kopaneng tsa plug tse kentsoeng ka mokelikeli o le mong, ebe li phetheloa ka setaele se le seng sa NC.

Empa motheo o lula o sa fetohe: ha ho karolo e tlohang Qingdao ntle le haeba e feta teko ea ts'ebetso e ts'oanang le kopano ea ho qetela. Haeba ts'ebeliso ea hau e hloka hore ho se ke ha e-ba le tšitiso ho khoholeho ea mobu, botsitso ba sebopeho, kapa ts'ebetso ea metallurgical - polaka ea hau e latelang ea Stellite e qala mona.
