Xa iinjineli zichaza Stellite 20 Izihlalo zevalve ezinxitywayo eziphezulu, ezinobushushu obuphezulu, i-pump plungers, okanye amakhonkco ombhobho we-turbine, abakhethi nje nayiphi na ingxubevange esekwe kwi-cobalt-bakhetha izinto ezifuna ukuchaneka kwi-metallurgy kunye nomatshini. Kodwa ukukhangela okuthembekileyo Umzi-mveliso weStellite 20 amaqabane ahlala engumceli mngeni othe gqolo. Sibone iiprojekthi ezininzi zilibazisekile-hayi ngeziphene zoyilo, kodwa ngonyango olungaguquguqukiyo lobushushu, isitokhwe esingaqinisekisiweyo, okanye idimensional drift emva koxinzelelo loxinzelelo. Kwiinkqubo ze-hydraulic ezisebenza kwi-700 + bar, ukuphambuka kwe-0.015 mm kwisihlalo seplagi ye-Stellite 20 kunokubangela ukuvuza kwangaphambi kwexesha. Ibhetshi enye enolwahlulo lwekhabhoni engaphandle kwe-spec iphazamise yonke imveliso yeempompo ze-OEMs ezikude nonxweme.
Kutheni iStellite 20 ingeyiyo nje “Enye iSuperalloy”
I-Stellite 20 ayifakwanga isitampu kwi-generic cobalt-chrome inventory. Ukusebenza kwayo kuxhomekeke kulawulo oluluqilima lwezinto ezine ezixhomekeke kwelinye: ichromium (28–32%), itungsten (4–6%), ikhabhoni (0.2–0.4%), kunye ne-carbide morphology. Ukuphambukela ngaphandle kwezo festile-kwaye ngakumbi ukuba inethiwekhi ye-eutectic carbide yenza i-coarse, bands edibeneyo endaweni ye-fine, amasuntswana ahlakazekileyo-ulahlekelwa ukuchasana ne-galling, i-micro-pitting, kunye nokudinwa kwe-thermal. Uhlalutyo lwehlabathi lokwenyani lubonisa ukungaphumeleli kwentsimi ukubuyisela emva kwingcambu enye: ukungahambelani kwezinto, kungekhona inxalenye yejometri. Yiyo loo nto abasebenzisi abakumgangatho ophezulu bengabuzi ukuba "Ngaba unomatshini weStellite 20?" Babuza "Uyiqinisekisa njani yonke i-microstructure yeqashiso? Ingaba ingot yakho eqinisekisiweyo ye-AMS 5387 ivela phi?
Yintoni eyahlula iFactory yeStellite eyinyani engama-20 kwiMachinist Jikelele
Yinyani Umzi-mveliso weStellite 20 umnikazi wekhonkco lenkqubo-hayi nje isisikelo sokugqibela. Iqala nge-AMS 5387 eqinisekisiweyo okanye i-T800-grade billet, eqinisekisiwe nge-OES kunye ne-PMI ngaphambi kokunyibilika. Ukwenziwa kotyalo-mali kufuneka kusebenzise imibumbo yeqokobhe leceramic ekwaziyo ukubamba ±0.05 mm ukunyamezela kumacandelo anodonga olucekethekileyo—akukho zinqumlo zokugalela esantini. Unyango lobushushu alukhethi; isisombululo se-annealing kwi-1175 ° C ± 10 ° C elandelwa kukupholisa komoya okulawulwayo kunyanzelekile ukunyibilikisa i-carbides yesibini ngaphandle kokugqithiswa. Emva koko kuza inxalenye enzima: umatshini. Ubulukhuni be-Stellite 20 (i-40-45 HRC njenge-cast) kunye nokuthanda ukuqina komsebenzi kufuna i-5-axis ye-CNC yamaqonga ane-spindle coolant, i-carbide tooling eyenzelwe i-cobalt alloys, kunye namazinga okutya alinganisiweyo ukuze aphephe i-edge eyakhelweyo. I-misstep enye-ukufaka okungenamsebenzi, ixesha lokuhlala eligqithisileyo-yenza ii-microcracks ezingaphezulu zibe ziindawo zokuqalisa phantsi kokulayisha umjikelo.
- Ukulandeleka kwezinto: Yonke icandelo le-Stellite 20 liphethe i-ID ekhethekileyo edityaniswe nelogi yayo yokunyibilika, itshati yomjikelo wokunyanga ubushushu, kunye nengxelo yokuhlola yeCMM.
- Uzinzo lweDimensional: I-post-machining yokunciphisa uxinzelelo ikhusela i-warpage kwiiflange ezibhityileyo okanye iishafti ezinde.
- Umphezulu imfezeko: Akukho kutsha kokusila; konke ukugqiba kusebenzisa iinkqubo ezinobushushu obuphantsi njenge-honing okanye i-electropolishing
- Ukuqinisekiswa okusebenzayo: Amalungu abalulekileyo avavanywa ngoxinzelelo, ukujongwa kwedayi, kunye nokuqina kwemephu-hayi nje ukujonga okubonakalayo.
Iindleko zokuLula-kwaye kutheni iNgafanelanga
Abanye abathengi baleqa iikowuti ezisezantsi ngokwamkela iStellite 20 elingana nelaphu elingangqinisiswanga okanye esenziwe ngoomatshini kwizixhobo ezininzi zevenkile yemisebenzi. Isiphumo? Iindleko zizonke eziphezulu zobunini. Silandelele ii-OEM ezintathu zehydraulic zaseMntla Melika ezitshintshe ababoneleli ukuze bonge i-12% kwiyunithi nganye. Kwiinyanga ezili-18, ezimbini ziye zabika i-23% yamazinga aphezulu okusilela ebaleni kwizindlu zepiston pump cylinder. Ingcambu yesizathu: ukungahambelani kwe-carbide dispersion kukhokelela ekunxibeleni okukhawulezileyo kwindawo yokufunxa. Ukutshintsha iiyunithi ezingaphumelelanga kubiza i-4.7 × ixabiso lenxalenye yokuqala-kubandakanywa nexesha lokuphumla, abasebenzi, kunye namabango ewaranti. Ngeli xesha, abathengi abasebenzisana ngokudibeneyo ngokuthe nkqo Umzi-mveliso weStellite 20 imisebenzi yabona ixesha eliphakathi kokusilela linyuka ngama-310% kuzo zonke iiassemblies zempompo kunye nee-valve ezininzi.
Ukujonga Phambili: Apho Ukuchaneka Kudibana Nokuqikelelwa
Umda olandelayo awukho nje ukwenza izinto ezinzima-kukufaka ukuqikelelwa kwinqanaba ngalinye. Abavelisi be-Stellite abakhokelayo abangama-20 ngoku badibanisa ukuhamba komsebenzi kwamawele edijithali: ukulinganisa ukulinganisa kuqinisekisa ukuzaliswa kwesikhunta kunye nokuqina ngaphambi kokuthululwa kokuqala; I-in-process imaging thermal iqinisekisa ukufudumeza okufanayo ngexesha lokutshisa; Ukucwangciswa kwendlela yeCMM encediswa yi-AI kunciphisa ixesha lokuhlola ngama-38% ngaphandle kokuncama ukhuseleko. Kwizinto ezibalulekileyo zobuthunywa, oku kuthetha ukuba akukho nto imangalisayo kwi-FAT-okanye ebaleni. Njengoko izixhobo ze-oyile zityhalela kubomi benkonzo yeeyure ezingama-20,000 kwaye iimpompo zangaphantsi kolwandle zisebenza kwi-150°C ngokuqhubekayo, ukuthembeka akunqweneleki. Yenziwe ngobunjineli, yaqinisekiswa, kwaye ibhalwe-inxalenye ngenxalenye, iqashiso ngeqashiso, unyaka nonyaka.
