Xa impompo ye-hydraulic ingaphumeleli kwi-oil rig ye-offshore-okanye i-valve yoxinzelelo iyaqhekeka ngexesha lovavanyo lomjikelo ophezulu-isizathu esisisiseko sihlala sibuyela kwisigqibo esinye: ukhetho lwezinto eziphathekayo. I-cobalt esekwe kwi-alloy mechanical parts ayisiyiyo nje ileyibhile yomthengisi. Sisiqinisekiso esisebenzayo kwiinkqubo apho ukothuka kwe-thermal, ukunxiba kwe-abrasive, kunye nemithwalo egciniweyo ye-20,000-psi isusa umda wempazamo.
Kutheni i-cobalt alloys ifuna ukuveliswa okukhethekileyo-kungekhona umatshini jikelele
I-Cobalt-chromium superalloys efana ne-AMS 5387 kunye ne-T800 "ayinzima kumatshini." Banobutshaba obunamandla: ukusebenza nzima ngokukhawuleza kunokuba isixhobo sinokusikwa, ukugquma ngokufudumeleyo ngokwaneleyo ukubambisa ubushushu kwi-interface, kunye ne-microstructurally enomdla kuxinzelelo olushiyekileyo okanye ukupholisa okungalinganiyo. Siye sabona iivenkile zizama imilomo ye-T800 kwii-mills eziqhelekileyo ze-CNC-kuphela ukukrazula i-60% yenqaku lokuqala eliqhutywe kwi-micro-cracking ngexesha lonyango lokugqibela lobushushu. Impumelelo ifuna ngaphezulu kokufakwa kwe-carbide. Ifuna ukuhamba komsebenzi okudityanisiweyo kokuphosa-omatshini, ukulawulwa kweatmosfera ngaphambi kokurhabaxa, kunye neendlela zesixhobo eziguqukayo ezikhokelwa yi-CMM ezilandelela ukuphambuka kwexesha lokwenyani kwizindlu zempompo ezinodonga olucekethekileyo.
Kungenxa yoko le nto i-cobalt yokwenyani esekwe kwi-alloy mechanical parts iqala phezulu-ekulandelekeni kwezinto. Yonke i-billet ye-AMS 5387 esiyiqhubayo iphethe iingxelo zovavanyo olupheleleyo, kunye nohlalutyo lwe-spectral oluqinisekisiweyo ngokuchasene ne-ASTM E1099 kunye nobungakanani beenkozo eziqinisekisiweyo nge-ASTM E112. Akukho kutshintshwa kwebhetshi. Akukho kutshintshwa “kwibakala elilinganayo”. Ukuba umzobo wakho uchaza i-AMS 5387, ufumana i-AMS 5387-hayi ifana ne-0.3% ngaphantsi kwe-chromium kunye nobunzima obushushu obuphantsi.
Izakhono ezine ezingenakuxoxisana emva kweenxalenye ze-cobalt ezibaluleke kakhulu
Iqabane elithembekileyo kufuneka lihambise ukuhambelana-kungekhona kanye kuphela, kodwa kwi-500-unit unit runs runs kunye ne-10-year-life expectations. La ngamakhono esiwaqinisekisayo phambi kokucaphula:
- Uzinzo lweDimensional ngokusetyenzwa komhlanganiselwa: I-Sand-cast cobalt alloy plugs iyancipha ngokungalindelekanga. Isisombululo sethu? Iinqununu ezifakwe kwi-investment kunye ne-CNC-ezigqityiweyo zokutywinwa-ezibambe i-± 0.015 mm kwi-diameter ye-120-mm ngaphandle kokuphazamiseka kwe-post-machining.
- Umphezulu imfezeko phezu kokugqitywa komphezulu: I-Ra 0.4 µm ayithethi nto ukuba ukukrazula kwe-micro-kumema ukudinwa kwangoko. Sisebenzisa i-RPM ephantsi, i-high-feed finishing passes ngezixhobo eziphathwa nge-cryogenically-kwaye siqinisekise ingqibelelo engaphantsi komhlaba ngokusebenzisa umfanekiso we-SEM onqamlekileyo kumanqaku okuqala.
- Ukuqinisekiswa okusebenzayo ngaphaya kwe-GD&T: I-cobalt alloy nozzle ayivunywanga emva kokuhlolwa kweCMM. Ihamba kwi-calibration calibration kwi-350 ° C, ukuvavanywa kokuguguleka kunye ne-80-grit silica slurry kwi-12 m / s, kunye nokuhlolwa kwe-ultrasonic kwi-porosity yangaphakathi kwi-ASTM E1961 iNqanaba lesi-3.
- Ukulandeleka okukhokelela kuhlalutyo lokusilela: Inxalenye nganye ihanjiswa ngesatifikethi esinekhowudi ye-QR edibanisa inombolo yobushushu ekrwada, iilogi zomjikelo wesithando somlilo, izitampu zexesha lokuhlola, kunye ne-ID yomsebenzisi. Xa ukusilela kwebala kusenzeka, iinjineli aziqikeleleli-zikhetha unobangela oyintloko ngeeyure, hayi iiveki.
Apho abathengisi bamayeza afana nalawo enziwe afana nalawo enziwe ngabenzi bawo bengaphumeleli—kwaye iingcaphephe ziyazisa
Abanye abavelisi baphatha i-cobalt alloys "njengenye isinyithi esingaqhelekanga." Bacaphula ngokusekelwe kubunzima, kungekhona imbali ye-thermal. Bakhupha i-outsource cast kwi-third party foundries abangenawo amava e-cobalt-emva koko bayazabalaza nesakhiwo se-dendritic esingahambelaniyo. Batsiba i-anneal yokuthomalalisa uxinzelelo phambi komatshini wokugqibela, bebangela i-warpage kwizindlu ze-piston pump cylinder emva kokudibana.
Siye saba nabathengi abatshintshela phakathi kweprojekthi emva kokufumanisa ukuba umthengisi wabo wangaphambili usetyenziselwe isilaphu se-cobalt esisetyenzisiweyo esineprofayile zomkhondo ezingangqinwanga. Isiphumo? Ukugalela kwangaphambi kwexesha kwi-winch centre shaft rollers phantsi komthwalo we-cyclic torsional. Impendulo yethu yayingekokutshintsha nje-yayikuphononongo oludibeneyo lwe-metallurgical, amaxesha ahlaziyiweyo onyango lobushushu, kunye nohlengahlengiso lweendlela zokuhambisa ezipholileyo kwinkqubo ye-CNC. Olo ludibaniso oluthe nkqo: ukuphosa, umatshini, unyango lobushushu, kunye ne-NDT phantsi kophahla olunye, ngolwazi lwenkqubo ekwabelwana ngayo-hayi i-handoffs.
Ukukhetha i-cobalt-based alloy mechanical parts factory: imibuzo emithathu eyahlula amaqabane kubathengisi
Phambi kokuba usayine i-NDA, buza ezi-kungekhona iimpendulo zentengiso, kodwa ubungqina obubhaliweyo:
- "Ndibonise amaqashiso akho amathathu okugqibela e-AMS 5387-iziqinisekiso zemill, iinkuni zokunyanga ubushushu, kunye neengxelo zokugqibela zeCMM." Ukungqinelana kubonisa kumaphepha, kungekhona izithembiso.
- "Ngobuphi ubude bakho obungaxhaswanga kwiishafu ze-T800 kwi-Ø45 mm-kwaye ulawula njani ngokuthe tye ngexesha lokujika?" Imida yelizwe lokwenyani ibonisa ukukhula kwenkqubo.
- "Ukuba uyilo lwethu lwempompo yezindlu lufuna udonga oluyi-0.8-mm kufutshane nekona yangaphakathi engama-90 °, ithini i-engile yakho encinci yedrafti-kwaye uyiqinisekisa njani ingqibelelo kulo mmandla?" Oku kuvavanya ubuchwephesha bokuphosa, hayi ubuchule bomatshini kuphela.
