Xa iinkqubo zoshishino zifuna ukunyamezela kwe-zero ngenxa yokungaphumeleli-iimpompo ze-hydraulic ezisebenza kwi-bar ye-350, ii-valve ze-offshore ezivezwe kumanzi olwandle kunye ne-H₂S, okanye i-winch shafts enyamezela imithwalo ye-cyclic torsional-ukuthembeka kwecandelo akusiyo inkcazo. Ngumahluko phakathi kwexesha lokuphumla kunye nexesha elingxamisekileyo. Yiyo loo nto iinjineli zaseMntla Melika, eJamani, naseSingapore zisiya zicacisa iinxalenye ze HT300 umzi-mveliso: hayi njengomboneleli wegeneric, kodwa njengeqabane lobuchwephesha elilungelelaniselwe ukusebenza kwesinyithi esibalulekileyo.
Kutheni "i-HT300" ingeyiyo nje iModeli yeNombolo-yiNkqubo yokutyikitya
Igama elithi HT300 livela kwimizimba yevalvu yoxinzelelo, izindlu zepiston pump cylinder, kunye nemilomo ye-cobalt alloy ethunyelwe kwihlabathi liphela. Kodwa akukho ngqiqweni. I-HT300 ibhekiselele kunyango oluqinisekisiweyo lobushushu + iprotocol yomatshini ephuhliswe ngaphezulu kweminyaka eyi-12 yokucokisa i-microstructure yentsimbi etyhidiweyo yozinzo lwe-dimensional under thermal cycling. Siye sabona abathengi betshintsha ukusuka kwi-EN-GJS-400-15 eqhelekileyo ukuya kwi-HT300-grade iron xa izindlu ze-cylinder ziphazamisekile emva kweeyure zokusebenza ze-8,000-nangona kudlula ukuhlolwa kokuqala kwe-CMM. Oyena nobangela? Umlinganiselo ongalawulwayo wepearlite-to-ferrite kwi-as-cast matrix. Umjikelo olawulwayo wokudibanisa we-HT300 uqinisa loo mahluko ukuya ku-±0.8% kuzo zonke iibhetshi-ingqinwe nge-metallography yokukhanya kunye nobulukhuni bemephu, hayi nje ukufundwa kweBrinell.
I-No-Compromise Alloy Processing-Apho i-AMS 5387 idibana ne-Real-World Machining
Buza nayiphi na injineli yomgangatho wevenkile malunga nokwenza i-AMS 5387 cobalt-nickel alloy: incoko, ukunxiba izixhobo, ukuqina komsebenzi. Omnye umthengi eTexas uxele i-47% yereyithi ye-scrap kwi-cobalt alloy plugs kusetyenziswa ukufakwa kwe-carbide eqhelekileyo kunye ne-coolant-through spindles. Isisombululo sabo sasingekokutya okukhawulezayo-yayikucinga kwakhona lonke ulandelelwano. Kumzi-mveliso weHT300, iinxalenye ze-AMS 5387 zifumana isiqabu soxinzelelo lwangaphambi komatshini (1,050°C/4 hrs/argon atmosphere), kulandele uzinzo lwe-cryogenic ku-−196°C phambi kokuba kudlule iCNC yokugqibela. Sisebenzisa i-polycrystalline diamond (PCD) isixhobo esine-3 ° i-rake angles negative-hayi ngenxa yokuba iyabiza, kodwa ngenxa yokuba isusa i-microcracking engaphantsi komhlaba eyenza ukukhathala kwangaphambi kwexesha kumacandelo epompo yoxinzelelo oluphezulu. Oku akuyothiyori. Zonke iinqanawa ze-T800 ezisekwe kwi-nozzle kunye ne-batch epheleleyo yokulandeleka: i-ID ye-log yesithando somlilo, i-curve yezinga lokupholisa, kunye nengxelo yokuhlolwa kwe-ultrasonic post-machining.
Udibaniso oluthe nkqo olunikezela ngolawulo-hayi nje ukuthengisa
"Idityaniswe ngokuthe nkqo" ithetha encinci ngaphandle kokuba isombulula iingxaki zokwenyani. Qwalasela iziseko zempompo zeenkqubo ze-booster zangaphantsi kolwandle. I-OEM yaseYurophu idinga i-ISO 13715-ehambelana ne-GD & T kwi-210 kg yesanti yokuphosa-kunye neempawu ezibalulekileyo zedatum ezigcinwe kwi-± 0.05 mm emva komatshini. Umthengisi wabo wangaphambili ukhuphele ngaphandle kunye nokwenza oomatshini ukwahlula abathengisi. Isiphumo? I-38% yamacandelo enqaku lokuqala ayiphumelelanga ukulungelelaniswa kwe-metrology ngenxa yokutshintsha kokungunda okungachazwanga kunye nokungahambi kakuhle kokususwa kwempahla. Umzi-mveliso weHT300 uphatha zombini kwindawo enye eqinisekisiweyo ye-ISO 9001: utyalo-mali kumacandelo anodonga olucekethekileyo, ukugalelwa kwesanti kwiziseko ezikhulu zesakhiwo, emva koko kwenziwe oomatshini abakwi-axis ezintlanu kunye ne-in-process laser probing. Okubaluleke kakhulu, bondla idatha ye-CMM emva kokulungiswa kwephethini yokuphosa-ukuvala i-loop phantsi kweeyure ze-72. Akukho handoffs. Akukho tyala-kutshintshwa. Ukuphindaphinda nje okuqikelelweyo.
Oko Kufunwa Ngoononjineli—Asikuko Oko Iincwadana Ezinemifanekiso Zithembisayo
- Ukuqinisekiswa kwe-GD & T ngaphambi kokusika isinyithi: Sijonga imizobo yakho malunga neengozi zokupakishwa-ingakumbi xa ii-datum zibhekiselele kwimigangatho engoomatshini kwii-substrates. Kufunyenwe iingxabano ezili-12 ezingabhalwanga kuyilo lwe-hydraulic manifold yomthengi ngexesha lovavanyo.
- Material substitution transparency: Ukuba i-ASTM A494 iBanga le-CD4MCu liyasilela kwi-chloride yokuchasana nomngxuma, siphakamisa i-UNS R31233 (T800) enedatha yovavanyo lokubola-hayi nje idatha yedatha.
- Ukuhanjiswa okubhityileyo ngaphandle kokurhweba ngomgangatho obhityileyo: Iiodolo zomthamo ophakathi zithunyelwa ngeentsuku ze-18-22. Akunjalo ngenxa yokuba iikona zisikiwe-kodwa ngenxa yokuba ii-ovens zokuphatha ukushisa ziqhuba kwiishedyuli zokugcinwa kwangaphambili, kwaye imigca yokugqiba isebenzisa ukuqinisekiswa komgangatho ozenzekelayo.
Ukuthembeka kuqala ngaphambi kokuba inxalenye ishiye indawo yokugcina impahla. Iqala ngoqeqesho lwe-metallurgical, iqhubeka ngokuqiniseka kwejometri, kwaye iphela kuphela xa icandelo lihambisa ubomi benkonzo elinganisiweyo-phantsi komthwalo, phantsi koxinzelelo, phantsi kokulindela. Lowo ngumgangatho we-HT300 wefektri. Hayi njengebango. Njengesiphumo esilinganisiweyo.
