Amacandelo amashishini asebenzayo aphezulu awanyamezeli ukuxhatshazwa-ingakumbi xa esebenza phantsi kwe-30,000 psi uxinzelelo lwe-hydraulic, i-650 ° C yokukhupha i-gas exposure, okanye i-abrasive abrasive eqhubekayo kwi-oilfield downhole izixhobo. Yiyo loo nto iinjineli kulo lonke elaseMntla Melika, eJamani, naseSingapore zisiya zigqitha kubaboneleli begeneric kwaye baye ngqo kwi mveliso yemetalurgy ephuculweyo ekwaziyo ukuhambisa kungekuphela nje iinxalenye-kodwa i-metallurgically eqinisekisiwe, izisombululo eziqinisekisiweyo ezisebenzayo. Siye sabona kuqala: i-cobalt alloy nozzle ingaphumeleli kwi-42,000 cycles kuvavanyo lwe-high-pressure injection ye-fuel-kungekhona ngenxa yoyilo, kodwa ngenxa yokuba iprofayili ye-sintering yomboneleli ikhutshwe nge-± 8 ° C kwiibhetshi. Kulapho ukuchaneka kuphelela khona kwaye umngcipheko wokusebenza uqala.
Kutheni "uBuchule" buthetha ngaphezulu kwePowder eNgcono nje
Inkqubela phambili yokwenyani kwi-powder metallurgy iqala ixesha elide ngaphambi kokuba ucinezele okanye ucofe. Iqala ngokulandelelwa kwezinto ukuya kwi-melt batch number, i-atmospheric elawulwayo i-sintering kunye ne-oksijini yoxinzelelo oluyinxenye ≤10⁻⁶ i-atm, kunye nonyango lwe-post-sinter lokushisa olulinganiswe kwi-AMS 2750E ukunyamezela kwe-pyrometer. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha yonke inxalenye ye-cobalt ye-cobalt ye-AMS 5387 ngokungathi iya kutywina i-subsea blowout. Oko kuthetha ukuba akukho xinzelelo oluluhlaza, akukho kukhula okuziinkozo okungaxelwanga ngexesha le-HIP, kwaye akukho tshintsho lwe-dimensional ngaphaya kwe-± 0.015 mm emva kokunciphisa uxinzelelo-oluqinisekiswe yi-CMM scans kuwo wonke amaqashiso, kungekhona nje iisampuli zenqaku lokuqala.
Siye saqaphela iingongoma ezintathu eziphindaphindiweyo zokungaphumeleli kumacandelo e-PM abonelelwa ngabathengi: (1) i-pore morphology engahambelaniyo ebangela ukukhathala kwangaphambi kwexesha ukuqaliswa kwe-crack in piston pump cylinder housings; (2) iileya zeoksidi yomphezulu ukusuka kwi-non-vacuum sintering ebangela ukuhlwa kwegalvanic kwiziseko zempompo yentsimbi; (3) intsalela yekhabhoni yesibophelelo ekhokelela kwi-microcracking ngexesha lokwenziwa kwe-T800 ialloy center shaft rollers. Isisombululo sethu? I-workflow edibeneyo ethe nkqo-isiqinisekiso sezinto eziluhlaza → i-debinding elawulwayo → i-vacuum sinter-HIP → ukuchaneka kwe-5-axis ye-CNC → i-ASTM E112 yokuqinisekisa ubungakanani bengqolowa-eyenziwe phantsi kophahla olulodwa kunye nokulandeleka okupheleleyo kwedijithali.
Apho IiNkqubo zeHybrid zokuCasa-Machining zizisa iROI yokwenyani
Ezinye iinjineli zithatha i-powder metallurgy endaweni yokuphosa. Ayenzi-iyayizalisekisa. Kwiijiyometri ezintsonkothileyo ezifana nemizimba yevalvu yoxinzelelo kunye neepaseji zokuqukuqela zangaphakathi kunye neeflange ezinyukayo zangaphandle, sidibanisa utyalo-mali oluyimilo ekufutshane ne-net-shape kunye ne-PM yeendawo zokutywina ezibalulekileyo. Ngoba? Ngenxa yokuba ukujula kuzisa imfezeko yesakhiwo ngexabiso eliphantsi kumacandelo amakhulu, ngelixa i-PM ifezekisa i-99.8% yoxinaniso kunye ne-Ra ≤0.4 µm umphezulu wokugqiba kanye apho ukutywinwa kwenzeka khona. I-OEM enye yaseYurophu yehydraulics yehlise ixabiso lilonke ngevalvu nganye ngama-22% isebenzisa le ndlela yokuxubana-akukho luhlenga-hlengiso, akukho kufaneleka, inkqubo yokucwangcisa ekrelekrele nje.
Oku akuyothiyori. Siqhuba zombini ukuphosa isanti kunye nemigca yokuphosa utyalo-mali ecaleni kwendawo yethu ye-PM-hayi njengamasebe ahlukeneyo, kodwa njengeendawo ezihambelanayo kwinethiwekhi enye yemveliso. Xa umthengi ethumela umzobo we-GD & T we-winch yemoto ye-winch shaft roller, iqela lethu livavanya ukuba ingaba ijenali yokuthwala ifanele ifakwe i-sintered-and-finished (ukumelana nokunxiba) ngelixa icandelo le-spline liphonswa-kunye noomatshini (ngenxa yamandla obunzima). Isigqibo sixhomekeke kwiimephu zomthwalo wokwenyani, hayi iinkcukacha zekhathalogu.
Ulawulo loMgangatho othi iiNjineli zithembe ngokwenene
"Isiqinisekiso se-ISO 9001" sivela kwiwebhusayithi nganye yomthengisi. Okubalulekileyo kukuba kwenzeka ntoni xa inxalenye ingaphumeleli ukuhlolwa. Kwiziko lethu le-Qingdao, yonke icandelo elaliwe libangela iprotocol yengcambu: uhlalutyo lwe-metallographic cross-section, imephu ye-SEM-EDS yokwakheka, kunye ne-sintering profile replay. Kwikota yokugqibela, silandele i-batch ye-cobalt alloy plugs kunye nobunzima obungahambelaniyo kwi-drift ye-thermocouple calibration drift kwisithando somlilo se-sinter-ilungiswe ngaphakathi kwemizuzu ye-90, kunye neengxenye ezichaphazelekayo ezithunyelwayo. Elo nqanaba lolawulo lisebenza kuphela xa umgangatho ungelosebe-ufakwe kulo lonke uluhlu lokukhangela imihla ngemihla.
- Ukuqinisekiswa kwezinto ezingenayo: Uhlalutyo lwe-Spectrometric + uvavanyo lwe-ultrasonic lwe-voids yangaphakathi
- Ukubeka iliso kwinkqubo: Ixesha lokwenyani lokungena umoya wokungena nge-alam ezenzekelayo e-O₂> 5 ppm
- Ukuhlolwa kokugqibela: I-CMM + iprofilometry ye-optical + uvavanyo loxinzelelo olusebenzayo nge-API 6D okanye i-ISO 5211
- Ukulandeleka: Imbali enekhowudi ye-QR efikelelekayo kubathengi-kubandakanya ii-certs zemathiriyeli ekrwada, iilogi zesithando somlilo, kunye neengxelo zokuhlola.
Yintoni omawuyibuze ngaphambi kokuba usebenzisane neFactory yePowder Metallurgy
Musa ukubuza "Ngaba ungayenza le nxalenye?" Buza endaweni yoko: "Ukuqinisekisa njani ukuphindaphindwa kwe-sintering kwimijikelo ye-10,000?" Okanye: "Ndibonise iingxelo zakho ezintathu zokugqibela ze-AMS 5387 zokungahambelani nendlela ozivale ngayo." Elona linamandla mveliso yemetalurgy ephuculweyo iimpendulo ngedatha, hayi iincwadana. Baza kwabelana ngokuguquguquka kwabo okuqhelekileyo (okwethu: ± 0.15% kwi-500 kg amaqashiso), i-avareji yomphezulu wabo orhabaxa emva kwe-sintering (Ra 1.2–1.8 µm, elawulekayo ukuya kwi-0.3 µm ngokugqitywa okwesibini), kunye nobudlelwane babo bomthengi obude obude (iminyaka eyi-14, kunye nokusilela kwe-nickel kwintsimi ye-coba).
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha iindawo ezihlala zivaliwe, zihlale zomelele, kwaye zihlale kwinkonzo-kuba ukusebenza akulinganiswa kwiingxelo zelebhu. Ilinganiswa ngexesha lokuphumla, ukugcinwa kwamathuba, kunye neendleko ezipheleleyo zobunini ngaphezu kweminyaka eyi-15 yokusebenza. Nguwo lowo umgangatho wenjineli. Ngalo lonke ixesha.
