Ukukhetha okulungileyo ukuphosa inxalenye ayisiyonto yokukhetha eyona quote incinci. Kumalunga nokuthelekisa ukuziphatha kwe-metallurgical, ukuzinza kwe-dimensional, kunye nokulawulwa kwenkqubo kuxinzelelo lwehlabathi lokwenyani-uxinzelelo oluphezulu, ukuhamba ngebhayisikili eshushu, ukunxitywa kwe-abrasive. Siye sabona izindlu ezininzi zempompo ye-hydraulic ziqhekeka kwi-3,000 psi kuba ukunyamezela kwesanti akuzange kuqinisekiswe ngokuchasene neefowuni ze-GD & T. Abanye baye basilela kuvavanyo olusebenzayo emva konyango lobushushu-hayi ukusuka ekukhetheni okungalunganga kwe-alloy, kodwa amazinga okupholisa angahambelaniyo kuwo wonke umngxuma wokungunda. Ukuchaneka kunye nokusebenza kakuhle kweendleko akukhuphisani. Ziyadibana xa uyilo lokuphosa, ukukhetha izinto eziphathekayo, kunye nomatshini wokuphoswa kwe-post-cast usebenza njengenkqubo enye.
Qala ngeNdlela Yomthwalo—Kungekhona Umzobo
Yonke ingqibelelo ephezulu ukuphosa inxalenye iqala ngendlela amandla ahamba ngayo kuyo. I-piston pump cylinder housing ayigcini nje ukubamba ulwelo-idlulisela i-torque, iqulethe imithwalo ye-radial evela kwiindibano ezijikelezayo, kwaye ixhathisa i-axial thrust ngexesha loxinzelelo lwe-spikes. Oko kutshintsha yonke into: ukuhanjiswa kobukhulu bodonga, ukubekwa kwesikhuphukeli, ijiyometri yokugawula. Sakhe saphinda sayila kwakhona i-cobalt-alloy valve body yempompo yodaka ye-oilfield ngokutshintsha isango eliphambili ukusuka phezulu ukuya kwicala. Isiphumo? Ukuphelisa i-microporosity kwindawo ebalulekileyo yokutywinwa kwegxala-kunye nokusika i-post-machining scrap ukusuka kwi-18% ukuya kwi-2.3%. Ngoba? Ngenxa yokuba isinyithi sasihamba ngokuhambelana kwindlela yomthwalo, kungekhona ngokuchasene nayo.
Oku akuyothiyori. Kuthetha ukukhankanya ubungqingqwa becandelo elisezantsi *kwindawo yokusebenza nganye*, hayi ngenxalenye nganye. Kuthetha ukuphonononga ii-engile eziyidrafti kungekuko ukukhutshwa komngundo kuphela-kodwa ngendlela ezichaphazela ngayo uxinzelelo loxinzelelo phantsi komthwalo we-cyclic. Kwaye kuthetha ukuphatha isibonelelo sokuncipha hayi njengepesenti emiselweyo, kodwa njengento eguquguqukayo ebotshelelwe kwixesha lokuqina lendawo kunye ne-alloy density gradient.
UKhetho Lwezinto eziphathekayo siSigqibo seNkqubo—Hayi nje iPhepha eliKhethekileyo
I-AMS 5387 i-cobalt alloy ayikho "ngcono" kune-ductile iron. Yimpendulo echanekileyo kuphela xa yakho ukuphosa inxalenye kufuneka igcine amandla esivuno angaphezu kwe-650 ° C * kwaye * ixhathise ukuqhekeka koxinzelelo lwesulfide kwindawo yerhasi emuncu. Kodwa kwaloo ngxubevange inye ifuna ulawulo olungqongqo lokunyakama kwisanti-kwaye yazisa ukunxitywa kwesixhobo esiqatha ukuba senziwa ngoomatshini ngaphandle kokuhanjiswa okupholisayo kunye nokukhetha ibakala le-carbide.
Silandelela izinto ezintathu ezingaxoxiswana ngazo zonke izigqibo eziphathekayo:
- Ukulandeleka kwebhetshi buyela kwinombolo yobushushu kunye neengxelo zovavanyo lwe-mill eziqinisekisiweyo-hayi nje "ihambelana ne-ASTM A487"
- Ukuqinisekiswa kweMicrostructure kusetyenziswa iisampulu ezinqamlezileyo zemimandla ebalulekileyo (umzekelo, ubungakanani beenkozo kwiindawo ezithwele i-winch center shaft rollers)
- Ukuqinisekiswa kwe-post-heat-treatment usebenzisa imephu yobulukhuni kwiikhonto ezintsonkothileyo, hayi nje iimvavanyo ze-Rockwell ezinenqaku elinye
Xa umthengi waseYurophu efuna ukugalelwa kwentsimbi engatyiwayo kwiziseko zempompo yamanzi olwandle, siye saqhuba iimvavanyo zokuthelekisa zobunzima kwiibhetshi ezintlanu ezahlukeneyo zesithando somlilo-nangona zonke zadibana ne-ASTM A743 Grade CF8M. Ibhetshi enye ibonise umyinge we-12% wobude obusezantsi ngexesha lekhefu ngenxa yokukhukuliseka kwe-Mn/Si encinci. Elo qela alizange liwushiye umgangatho wethu wesiseko.
Ukudityaniswa Kubetha i-Handoff-Ngalo lonke ixesha
Ukwahlula ukuphosa kumatshini kudala iindleko ezifihliweyo: kusetyenzwa kwakhona ukusuka kwiflash engenakuthelekiswa nanto, iindawo ezilahliweyo ngenxa ye-porosity engaphantsi komhlaba engakhange ibonwe, ukulibaziseka kokuhanjiswa kwiiprothokholi zokuhlola ezingalungelelanisiweyo. EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., CNC izixhobo zokulungisa ziyilwe *ngexesha* lophuhliso lwepateni—kungekhona emva kokuba ukuphoswa kugqityiwe. Abacwangcisi bethu benkqubo ye-CMM bafumana idatha ye-3D yokuskena kwi-molds yesanti eluhlaza *phambi kokugalelwa* kokuqala. Ngoba? Ukuqikelela apho utshintsho olungundoqo luya kutyhala imilinganiselo ngaphandle kokunyamezelana-kwaye uhlengahlengise ii-machining offsets ngokukhawuleza.
Oku kudityaniswa ngokuthe nkqo kuzisa iziphumo ezinokulinganiswa:
- Uzinzo lweDimensional luphuculwe ngama-40% kwimizimba yevalvu yoxinzelelo efuna ±0.025 mm ukunyamezela indawo
- Umphezulu wokugqiba ukuguquguquka uphakanyiswe ukusuka kwi-Ra 3.2 µm ukuya kwi-Ra 1.6 µm kumabhobho ombhobho we-cobalt-alloy-ngaphandle kokusila okwesibini
- Ukuncitshiswa kwexesha eliphambili leentsuku ezili-11 ukuya kwezili-17 kwii-odolo zomthamo ophakathi, zaqinisekiswa kwiiprojekthi ezingama-42 ngo-2023.
Kukwathetha ukwala imizobo “elunge ngokwaneleyo”. Xa umxhasi waseMntla Melika wasithumelela itshathi ye-GD&T enezingqinisiso zedatum engaqondakaliyo yezindlu zempompo yengxubevange ye-T800, sibuyisele inguqulelo ephawulweyo ebonisa kanye ukuba zeziphi iimpawu eziya kukhukuliseka phantsi kokwandiswa kwe-thermal-kwaye kwacetywa iindlela ezimbini ezizezinye ze-datum ezixhaswa ziziphumo zokulinganisa i-FEA.
Iindleko eziSebenzayo zihlala kwiinkcukacha ozilawulayo
Ukusebenza kwexabiso lokwenyani kuqala ngaphambi kokuba i-ladle yokuqala igalelwe. Kukhetha ukuphosa utyalo-mali phezu kwesanti kwiplagi encinci ye-cobalt-alloy-akunjalo ngenxa yokuba "intle," kodwa ngenxa yokuba iphelisa iiyure ze-3.5 zokuthatha ngesandla ngenxalenye nganye kwaye inciphisa ixesha lokuhlola lokugqibela nge-60%. Icacisa izibophelelo ze-ceramic ezisekelwe kwi-ZrO₂ ze-AMS 5387 castings ukunqanda ukukhutshwa komphezulu we-sodium ngexesha lokukhupha. Isebenzisa inkqubo yolawulo lweenkcukacha-manani kwiqondo lobushushu lokungunda *kunye* nokufuma kwe-ambient—hayi nje ubushushu obunyibilikayo.
Asilinganisi ixabiso ngeedola ngekhilogram nganye, kodwa ngexabiso lilonke ngokwenxalenye enikezelweyo enikezelweyo. Oko kuquka:
- Isantya se-scrap esibangelwa ziziphene ezinxulumene nokuphosa (i-porosity, ukuvalwa okubandayo, ukubandakanywa)
- Ixesha lesibini lokusebenza longezwe ngenxa yokungahambelani kwejiyometri
- Iiyure zobuNjineli ezichithwe ekusombululeni ukungangqinelani komda phakathi kwezigaba zokusaswa kunye nezomatshini
- Iindleko zolungiselelo lweendawo ezitshintshileyo zothutho-moya emva kokusilela ebaleni
Ngomnye umxhasi we-Southeast Asia umthengi we-winch shaft rollers yemoto yobunjineli, ukutshintshela kwi-iron ye-grey kwi-Custom-modified EN-GJS-600-3 i-ductile iron-ehlanganiswe nokupholisa okulawulwayo kunye nokunciphisa uxinzelelo-ukunciphisa iindleko zokugcina ubomi ngama-37% nangona ixabiso le-22% ephezulu yokuphosa.
Ukusebenza okuphezulu ukuphosa inxalenye Imveliso ifuna ngaphezulu kwezixhobo ezisisiseko okanye ii-CNC Mills. Ifuna iinjineli ezibambe ivalve yehydraulic eqhekekileyo ezandleni zabo ngo-2 a.m. kwaye balandele ukusilela emva kuyilo lwesikhuphukeli. Ifuna i-metallurgists eyaziyo indlela i-vanadium carbides eziphatha ngayo kwi-T800 alloy ngexesha lokuguqulwa kombuso oqinileyo. Ifuna iinkqubo ezisemgangathweni eziphatha yonke indawo yokuhlola njenge-loop yempendulo-kungekhona umgcini wesango. Ikamva lelamaqabane angaboniyo ukujula njengenyathelo elizimeleyo, kodwa njengomaleko wesiseko somjikelo wobomi wecandelo elichanekileyo-ukusuka kwisinyithi esinyibilikisiweyo ukuya kumsebenzi obalulekileyo.
