Xa iinjineli zichaza i-alloy steel investment casting factory iinkonzo, azikho nje uku-odola iinxalenye-zikhusela uzinzo lwe-dimensional under 400 MPa hydraulic loads, microstructural consistency kuwo wonke ama-500-unit batches, kunye ne-zero tolerance for porosity in the interfaces seat valve. Leyo yinyani yokusebenza emva kwamacandelo amashishini achanekileyo afana nezindlu ze-piston pump cylinder okanye i-AMS 5387 cobalt alloy nozzles-amacandelo apho ukuphambuka kwe-0.02 mm kubangela ukungaphumeleli kokusebenza.
Sizibonele mathupha: isixhobo se-oyile yaseMntla Melika i-OEM ilibazisekile ukuthunyelwa kweeveki ze-11 ngenxa yokuba umthengisi wabo "oqinisekisiweyo" we-alloy castings yentsimbi ayiphumelelanga kuvavanyo lwe-ultrasonic kwiiyure ezingama-72 emva kokunyanga ukushisa. Oyena nobangela? Ukungahambelani kokulandelelwa kwezinto ezikrwada kunye nekhemistri yebhetshi engaqinisekiswanga-hayi impazamo yokwenza. Eso siganeko satshintsha indlela esisondela ngayo kwi-alloy yentsimbi yokutyala imali kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Yiyo loo nto yonke i-T800 esekelwe kwi-winch center shaft roller iqala ngeengots eziqinisekisiweyo, hayi isitokhwe "esingenastainless-ehambelanayo" esiqhelekileyo.
Ukuchaneka kokwenyani kwi-alloy yentsimbi yokutyala imali kufuna ukuhlanganiswa ngokuthe nkqo-kungekhona nje ukuphosa, kodwa ulawulo lwe-metallurgical, ukugqitywa kwe-multi-axis, kunye nokuhlolwa kwe-GD & T-aware-konke phantsi kophahla olulodwa oluhambelana ne-ISO. I-Sand casting ibamba i-geometry eninzi; ukuphoswa kotyalo-mali kunikezela nge-0.05 mm Rz ukugqitywa komphezulu ofunekayo kubuso botywino obuguqukayo. Kodwa umahluko wokwenyani ulele kwinto eyenzekayo phakathi kwaloo manyathelo: imijikelo yonyango lobushushu ebekwe ixesha ukuya kwi-± 1 ° C, ukuqinisekiswa kwe-CMM yeempawu ezibalulekileyo ze-datum * phambi * kwaye * emva * koxinzelelo loxinzelelo, kunye nokulinganiswa kwe-optical of internal gating residues enokuthi imbewu yokudinwa iqhekeke kwiziseko zempompo yomjikelo ophezulu. Asikhupheli ngaphandle ukusetyenzwa kwe-thermal. Asitsibi iitshekhi zangaphambi komatshini wobulukhuni. Siqinisekisa yonke iqashiso ngokuchasene ne-ASTM A957 kunye ne-EN 13381-kuba "njengoko-cast" ayisiyo inkcazo; yivector yomngcipheko.
- Uqeqesho lwezinto eziphathekayo: Akukho mahluko ngaphandle kokusayinwa kobunjineli—nakwizinto ezincinci zokuhlanganisa. Xa umxhasi ecela i-316L endaweni ye-F22 yendlu yempompo yamanzi olwandle, siye saqhuba umfuziselo womgangatho wokurhwaphiliza kuqala. Isiphumo: 316L corrored 3.2× ngokukhawuleza kwi 85°C. Sibambe umgca kwi-F22-kwaye songeza i-duplex stainless cladding apho isantya sokuhamba singaphezulu kwe-4 m/s.
- Ukunyaniseka kwenkqubo: Amaqokobhe otyalo-mali agalelwa iwax kwi-120°C, hayi “ubushushu begumbi + nokufuma kwe-ambient.” Iipateni ze-wax zisebenza iiyure ezingama-72 zokuzinzisa i-vacuum ngaphambi kokufakwa kwe-ceramic slurry. Ngoba? Ngenxa yokuba ukufuma okushiyekileyo kubangela i-micro-blisters eziba zifakwe kwi-oxide inclusions ngexesha lokugalela.
- Ukuqinisekiswa okusebenzayo: Yonke indlu yevalve yoxinzelelo ifumana ubungqina be-hydrostatic kwi-1.5 × uxinzelelo olusebenzayo, emva koko uvavanyo lwe-helium lokuvuza kwi-1 × 10⁻⁹ mbar·L / s uvakalelo-kungekhona nje ukuphicothwa kwe-dimensional. Ukuba ayibambanga, ayihambi ngenqanawa.
Abanye baphikisa ngelithi iifektri zokuphosa ngaphandle kolwandle zibonelela ngamaxabiso angcono. Benza njalo-de ube ujonga iindleko zokuphinda usebenze kwakhona ukusuka kwisakhiwo esingahambelaniyo senkozo, okanye i-18,000 yeedola zentlawulo yothutho lomoya ukuze utshintshwe ngokukhawuleza emva kokusilela kwintsimi. Abathengi bethu eJamani naseTexas banika ingxelo nge-42% yexabiso eliphantsi lilonke lobunini kubomi benkonzo yeminyaka emi-3-hayi ngenxa yokuba iikowuti zethu ziphantsi, kodwa ngenxa yokuba isivuno sethu sokuqala singaphezulu kwe-94.7%, kwaye ukuphindaphinda kwethu okulinganayo kubamba ± 0.015 mm kwiiyunithi ezingama-200. Oko kuhambelana kuvela ekulawuleni lonke ikhonkco: ukufunwa kwezinto eziqinisekisiweyo, uhlalutyo lwe-spectral yangaphakathi, i-CNC-machine molds ceramics, kunye ne-laser-scan scan uthelekiso lokugqibela ngokuchasene ne-CAD yegama.
Ukuba isicelo sakho sifuna i-alloy yentsimbi yotyalo-mali yokuphosa amandla efektri ephatha i-AMS 5387 njengesiseko-hayi ngaphandle-ufuna amaqabane asebenze ngomatshini i-T800 kwi-32 HRC ngaphandle kokutshiphuza, aqinisekisa isithuba phakathi kwe-interdendritic kwi-cast microstructures, kunye nabaphatha i-callout ye-GD & T njengezibophelelo zekhontrakthi, kungekhona iingcebiso. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha obo buchule kwinyathelo ngalinye lenkqubo-kungekhona njengolwimi lokuthengisa, kodwa njengeeprothokholi zokuhlola ezibhaliweyo, iisampulu ezigciniweyo zogcino-mpepha, kunye nexesha lokwenyani leprofayile ye-thermal logs efakwe kwiwele ledijithali yecandelo ngalinye. Ukuchaneka akufezekiswanga kuhlolo lokugqibela. Ivalwe kwinqanaba lepatheni ye-wax, iqinisekiswe kwi-melt analysis, kwaye iqinisekisiwe xa inxalenye isinda kuvavanyo lokuqala lokunyamezela iiyure ezingama-500.
