Xa indlu yepompo ye-hydraulic iqhekeza phantsi kwe-350-bar yoxinzelelo-okanye i-cobalt alloy nozzle ihluleka emva kweeyure ze-420 zenkonzo ye-sour-gas-ingxaki ayikho nje inxalenye yokungaphumeleli. Kukwaphulwa kwekhonkco phakathi kwenjongo yoyilo kunye nenyani ye-metallurgical. Loo msantsa apho ngokuchanekileyo isiseko sesinyithi ifumana ubunzima bayo-kungekhona njengenkqubo yempahla, kodwa njengokwandiswa okulawulwayo, okukhokelwa yisayensi yesigwebo sobunjineli.
EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., sikubonile oku kudlala kwiiprojekthi ezili-178 zeOli yaseMntla Merika ii-OEMs, izihlanganisi zenkqubo yokwenziwa koxinzelelo loxinzelelo olukhulu lwaseJamani, kunye nabakhi bempompo baselwandle baseMazantsi-mpuma eAsia. Omnye umxhasi usithumelele imizobo ye-GD & T-enzima ye-AMS 5387 yepiston yepompo ye-cylinder yezindlu-ukunyamezela okuqinileyo: ± 0.015 mm kwi-ID ye-bore, i-surface finish Ra ≤ 0.8 µm, i-porosity yangaphakathi ye-zero kwiindawo ezibalulekileyo zoxinzelelo. Umthengisi wabo wangaphambili uhambise iinxalenye ezili-12. Kuphela i-3 iphumelele uvavanyo lwe-ultrasonic. Siqhube ukulinganisa inkqubo epheleleyo kuqala: imodeli yokuqinisa, imephu ye-thermal gradient, ukwenziwa kwegeyiti. Emva koko ukuphoswa, ukunyangwa ngobushushu, i-CNC-igqityiwe, kwaye i-CMM-iqinisekisiwe yonke iyunithi. Bonke abangama-24 badlula. Umahluko wawungelothamsanqa. Yayiluqeqesho oludityaniswe nolawulo lomatshini.
Ukuchaneka kokwenyani kwi isiseko sesinyithi iqala phambi kokuba ukungunda kuchukumise isanti okanye i-ceramic. Iqala ngokuphendula ngezinto eziphathekayo. Sifumana ialloys ye-cobalt-nickel kuphela kwii-mill ezibonelela ngeengxelo eziqinisekisiweyo zobushushu-AMS 5387, UNS R30006, T800-grade-traceable to melt melt, uhlaziyo lwekhemikhali, kunye nokuqinisekiswa kobungakanani beenkozo. Akukho "imindilili yebhetshi." Akukho ziqinisekiso zithunyelwe ngumboneleli ngaphandle kokutshekishwa komntu wesithathu. Xa umenzi we-valve yaseYurophu efuna i-19mm-diameter cobalt alloy plugs kwinkonzo ye-H₂S, basithumelele i-ASTM yabo ye-A995 Level II spec-kwaye sayifanisa ukuya kwi-0.03% ye-carbon deviation. Loo nqanaba lokuthembeka akwenzeki kwiivenkile eziphatha ukhetho lwe-alloy njengebhokisi lokukhangela.
Ukudityaniswa okuthe nkqo akuyiyo ijargon yokuthengisa apha-yindlela uzinzo lwe-dimensional lutshixelwa ngayo. Ukuphosa kwesanti kukodwa akukwazi ukubamba ± 0.02 mm kwisiseko sempompo engama-320 mm ubude. Kananjalo ukusetyenzwa kwe-CNC kukodwa akunakulungisa i-micro-shrinkage kwi-high-alloy steel castings. Kodwa xa ukuphosa, unyango lobushushu, kunye ne-5-axis milling kwenzeka phantsi kophahla olunye-kunye ne-metrology ekwabelwana ngayo, iifestile zenkqubo ezilungelelanisiweyo, kunye nophononongo oludibeneyo lwe-GD&T-iimpazamo zokupakishwa ziyawa. Sihlala sibambe i-0.008 mm flatness kwi-casts stainless steel castings enokulinganisa i-420 × 280 × 95 mm-emva kokunciphisa uxinzelelo, ukubetha, ukugqiba, kunye nokugqibela okunzima. Oko kufuna imbuyekezo yexesha langempela le-thermal kwi-CNC, kungekhona nje ukulungiswa emva kwenkqubo.
- Akukho "bhokisi emnyama" ephosayo: Yonke intsimbi okanye intsimbi yokuphosa ibaleka ngokulinganisa ukuqinisa; yonke inxalenye ye-cobalt alloy ifumana ukuqinisekiswa kwangaphambili kwe-microstructure nge-optical emission spectroscopy + i-SEM yokukhangela indawo
- Akukho mashini ayimfama: Idatha ye-CMM evela kwi-blank blanks feeds ngqo kwi-CNC toolpath optimization-ukunciphisa ukususwa kwempahla ukuya kuthi ga kwi-37% kwizindlu ezinzima
- Akukho QA yamaphepha kuphela: Ukulandeleka akulongeniso yedatha. Yithegi ye-laser ebonakalayo ekrolwe kwindawo nganye, enxibelelanisa kwiicerts zemathiriyeli ekrwada, iingxelo ze-NDT, iilogi zokunyanga ubushushu, kunye neefoto zokuhlola zokugqibela.
Abanye bacinga ukuba ukuphoswa kotyalo-mali ngokuzenzekelayo kulingana nokuchaneka okuphezulu kunokuphosa isanti. Ayonyani. Iqokobhe lotyalo-mali olungekho kakuhle ligqwethekile ngexesha le-dewaxing. Ukungunda kwesanti okukhawulezileyo kuphola ngokungalinganiyo, kudala uxinzelelo olushiyekileyo olujikayo ngexesha lomatshini. Eyona nto ibalulekileyo yinkqubo yobukrelekrele—kungekhona uhlobo lokungunda. Sisebenzisa ukugaywa kwesanti kwiindawo ezinkulu, ezinomthamo ophantsi wolwakhiwo olufana neerola ze-winch ye-winch centre shaft rollers (ukuya kuthi ga kwi-1,200 kg), kuba amazinga okupholisa alawulwayo kunye noshicilelo olungundoqo oluyinjineli luzisa ukufana kobunzima obukhulu kunotyalo-mali kumacandelo ashinyeneyo. Kwimilomo yecobalt encinci, ebhityileyo? Utyalo-mali luyaphumelela-kodwa kuphela ngokugalelwa kwe-vacuum-assisted kunye nolawulo lokuqinisa ulwalathiso. Ukuchaneka akubhakwa kwindlela. Yenzelwe kwisigqibo ngasinye.
Jonga phambili: Umda olandelayo awukho iziko zikhulu okanye ii-spindles ze-CNC ezikhawulezayo. Lulawulo lwenkqubo ye-hybridi-apho iziphumo zokulinganisa zondla iimodeli ezishushu kumaziko omatshini, apho i-in-situ strain sensors ilungisa iindlela zesixhobo esiphakathi, apho amawele edijithali aqinisekisa ubomi bokudinwa ngaphambi kokugalelwa kokuqala. I-QINGDAO QIANGSENYUAN TECHNOLOGY yakha obo buchule ngoku-kungekhona njengovavanyo lwaselabhu, kodwa njengesiseko semveliso. Siqinisekisa kwi-AS9100 yezixhobo zempompo ezibaluleke kakhulu kwi-aerospace. Sifanelekela i-HIP (i-isostatic eshushu yokucofa) kwi-cobalt castings ekufutshane. Kwaye siqeqesha iinjineli kungekhona nje ukufunda iiplani-kodwa ukuqikelela ukuba isinyithi esityhidiweyo siya kuziphatha njani kwijometri ethile, phantsi kweemeko zokupholisa ezaziwayo, kunye ne-alloy chemistry eqinisekisiweyo.
I-Foundry metal casting ayikho malunga nokugalela isinyithi kwimilo. Kumalunga nokuguqulela imfuno esebenzayo-uxinzelelo lwengqibelelo, ukuxhathisa ukunxiba, ukuzinza kwe-thermal-kwisiqiniseko se-metallurgical. Oko kufuna okungakumbi kunezixhobo. Ifuna amava nge-AMS 5387 iindlela zokuqhekeka. Ifuna ubungcali kwi-GD&T-driven casting allowances. Ifuna intembeko eyakhiwe ngaphezulu kwe-217 eqinisekisiweyo yokuveliswa kwemveliso-hayi izithembiso. Ukuba indlu yakho elandelayo yevalve ephezulu yoxinzelelo oluphezulu, icandelo lempompo yepiston, okanye inxalenye yealloy ekhethekileyo kufuneka yenziwe-ingabikho nje ukusinda-ke ukuchaneka kuqale kwakudala ngaphambi kokuba intlantsi yokuqala ibethe i-workpiece.
