Xa impompo ye-hydraulic ingaphumeleli kwi-oil rig ye-offshore-okanye i-valve ephezulu yoxinzelelo ibamba ngexesha lemisebenzi ebalulekileyo ye-cementing-isizathu esisisiseko asiyiyo ukuyila, kodwa ukuchithwa kwezinto eziphathekayo. Amalungu e-AMS 5387 eStellite awagugi ngokuthe ngcembe. Zisilela ngokukhawuleza: i-micro-cracks isasazeka phantsi koxinzelelo lwe-thermal ye-cyclic; i-carbide networks fracture phantsi kwe-abrasive slurry flow; umphezulu imfezeko uyawa emva ibhayisekile ephindaphindiweyo thermal. Siyibonile kumazwekazi amathathu-kwiindawo ezininzi zoLwandle oluMntla, izindlu zempompo ze-frac zaseTexas, kunye neendibano zokukhuthaza ukukhupha ityuwa kwi-Southeast Asia. Ngalo lonke ixesha, ukusilela akuzange kube ngamabona-ndenzile. Ilandele ipateni: idimensional drift ngaphaya kwe ±0.015 mm kwindawo yokutywina, ilahleko yobulukhuni be-Rockwell C62–65 emva kweeyure zokusebenza ezingama-4,200, okanye i-oxidation ye-intergranular kwiindawo ezichatshazelwe bubushushu ukusuka kwi-annealing engafanelekanga yasemva komatshini.
Kutheni i-AMS 5387 yeStellite Parts ifuna ngaphezulu kunokutshintshwa nje
I-AMS 5387 ayikho nje i-cobalt-based alloy-yinkqubo ye-metallurgical eyenzelwe ukuthembeka okugqithisileyo kokusebenza. Ukubunjwa kwayo (64-68% Co, 27-31% Cr, 0.9-1.4% C, kunye ne-Ni, W, Si, Mn) inikezela ukuchasana okukhethekileyo kwi-galling, i-corrosion fatigue, kunye ne-oxidation ephezulu yokushisa. Kodwa loo ntsebenzo ixhomekeke kulawulo oluchanekileyo lwezinto ezintathu eziguquguqukayo: i-microstructure homogeneity, i-machining-induced residual stress distribution, kunye nemfezeko yokugqibela yomphezulu. Inxalenye eyenziwe ngomatshini onesantya sokupholisa esingachanekanga okanye isicwangciso sendlela yesixhobo sinokuhlangabezana nokunyamezela kwe-GD&T—kodwa lusilele kuvavanyo lokungcangcazela kwiiyure ezingama-72. Siye saqinisekisa oku kuwo wonke amaqashiso emveliso ali-112: I-87% yokusilela kwangaphambi kwexesha kulandelelwe umva kwi-microcracking engaphantsi komhlaba eyaziswa ngexesha lokujika kokugqiba-hayi iziphene.
Kungenxa yoko le nto "ukutshintshwa" kulahlekisa. Into efunwa ngabaqhubi ukuqhubeka kokusebenza: i-coefficient yokwandiswa kwe-thermal efanayo, i-coefficient ehambelanayo ye-friction ngokuchasene ne-mating stainless components, kunye nokugcinwa koxinzelelo lwe-compressive surface ukuya kwi-0.3 mm ubunzulu. Oko kufuna ngaphezulu kokufumana isitokhwe sebha ekrwada. Ifuna ulawulo lwenkqubo yokuphosa (ukuphosa utyalo-mali olukhethwayo kwiijometri ezintsonkothileyo), izicwangciso ze-CNC ze-multi-axis ezinciphisa ukwakheka kobushushu, kunye nokuqinisekiswa okungonakalisi kusetyenziswa i-phased-array ultrasonics-ingeyiyo nje i-CMM yokuhlola.
Izinto eziNtathu ezingaThethwayo kwi-AMS 5387 Stellite Part Supply
Uninzi lwababoneleli baphatha i-AMS 5387 njengengcaciso yempahla yorhwebo. Abayenzi. Nantsi into eyahlula unikezelo olubalulekileyo kubuthunywa ekuthengeni izinto zentengiso:
- Ukulandelelwa kwezinto kwinani lobushushu-hayi nje isiqinisekiso sokusila. Ibhetshi nganye esiyiqhubayo inohlahlelo olupheleleyo lwespectrographic, ingxelo yobungakanani beenkozo (ASTM E112), kunye nokuqina kwemephu kumacandelo amahlanu anqamlezileyo. Akukho ngaphandle.
- Iiparamitha zoMatshini zitshixiwe kwifiziksi yesicelo. Kwizindlu ze-piston pump cylinder, sisebenzisa ukupholisa kwe-cryogenic nge-70 ° C ye-nitrogen inkungu kunye neendlela zesixhobo se-trochoidal-ukunciphisa uxinzelelo lwe-subsurface nge-43% ngokuchasene ne-coolant yesiqhelo.
- Ukuqinisekiswa okusebenzayo ngaphambi kokuthunyelwa. Yonke inxalenye ye-AMS 5387 Stellite ifumana uvavanyo lwenkonzo olufaniswayo: i-200-iyure ye-thermal cycling phakathi kwe-20 ° C kunye ne- +250 ° C, ilandelwa luvavanyo lokubola koxinzelelo kwi-1.5 × uxinzelelo lokusebenza. Idatha yokudlula/yokusilela ifakwe kwithegi yokulandeleka enekhowudi yeQR.
Abanye banokuxoxa ukuba imathiriyeli yesitokhwe eqinisekisiweyo iyawususa umngcipheko. Kodwa ubuntununtunu be-AMS 5387 kwimbali yobushushu buthetha ukuba i-ASTM F90-ethobela i-billet inokuphuhlisa isigaba se-sigma ukuba iphinda ifudunyezwe ngokungafanelekanga ngexesha lomatshini orhabaxa. Siyakuphepha oku ngokudibanisa unyango lokushisa kwi-workflow yethu-isisombululo se-annealing kwi-1175 ° C ± 5 ° C, emva koko ilawulwa ukupholisa umoya kwi-≤15 ° C / min-iqinisekiswe nge-thermocouples efakwe kwi-furnace efakwe kwi-ASME BPE.
Apho iStandard Catalog Solutions Fall Short
Ngaphandle kwe-AMS 5387 Amalungu eStellite awafane alingane neenkqubo zehlabathi. Sihlala sifumana imizobo ephawulwe "ASME B16.34 Class 900" kuphela ukufumanisa ubuso beflange bufuna ukuthungwa komphezulu oqhelekileyo wokugcinwa kwetywina kwinaliti ye-polymer ephezulu ye-viscosity. Okanye iplagi "eqhelekileyo" yoyilo olungahoyi iprofayili yokhukuliseko lwangempela ukusuka kwi-30% ye-sand-laden fluid-efuna i-tungsten carbide cladding kwindawo ehamba phambili, kungekhona i-coating efanayo.
Impendulo yethu ayisiyiyo "singayenza." Yithi: "Nantsi indlela esiyivavanye ngayo ijometri ngokuchasene nesantya sokuhamba kwakho, ukuhanjiswa kobungakanani besuntswana, kunye nomjikelo womsebenzi-kwaye nantsi indlela yokunxiba eqikelelweyo kwi-90%, 75%, kunye ne-50% yamazinga okuhamba." Sihambise ngaphezu kwe-2,300 engeyo-standard ye-AMS 5387 ye-Stellite components-ukusuka kwi-cobalt alloy nozzles ene-laser-etched yangaphakathi ye-swirl vanes ukuze iwine i-shaft rollers ene-asymmetric hardness gradients (i-HRC 64 kwicala lomthwalo, i-HRC 52 kwicala lokuqhuba). Isisombululo ngasinye siqala ngedatha yakho yokusebenza-hayi ikhathalogu yethu.
Ukukhetha iqabane, hayi uMboneleli
Ukuba icandelo lakho elilandelayo le-AMS 5387 Stellite lixhomekeke ekuphepheni ixesha lokuphumla leeyure ezingama-72 kwindawo ekude, jonga ngaphaya kweengcaphuno zexesha lokukhokela. Buza: Ngaba banokuphinda baphindaphinde umphezulu okhoyo wexabiso likaRa phakathi kwe ± 0.05 µm? Ngaba bayayigcina iisampulu ze-microstructural kubo bonke ubushushu ukuze kuhlalutywe uthelekiso? Ngaba banokubonelela nge-metallurgical cross-sections ebonisa ubuninzi be-carbide dispersion in 500x magnification?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ukusuka kule ndawo. Indawo yabo ehambelana ne-ISO eQingdao idibanisa utyalo-mali, i-5-axis CNC machining, kunye nonyango lwe-vacuum yokushisa-zonke ziphantsi kophahla olulodwa. Abawuthathi phantsi umsebenzi we-AMS 5387. Abayamkeli imizobo “njengoko injalo” ngaphandle kokuqinisekiswa kwe-GD&T. Kwaye abathumeli ngaphandle kweerekhodi zovavanyo ezisebenzayo ezibotshelelwe kwinombolo yakho yeodolo yokuthenga.
Ixabiso lokwenyani lenxalenye ye-AMS 5387 Stellite ayisiyiyo isixa se-invoyisi. Kukuvalwa okungacwangciswanga, isiganeko sokhuseleko ukusuka ekungaphumeleli kwetywina ngequbuliso, umonakalo onegama elivela kukutshintshwa okuphindaphindiweyo. Khetha amaqabane aphatha i-cobalt alloy alloy components njenge-inventory-kodwa njengezandiso zobunjineli zemvulophu yokuthembeka kwenkqubo yakho.
