Xa inkqubo ye-hydraulic ihluleka phantsi koxinzelelo lwe-bar ye-350, i-culprit ayinqabile ipompo-yinxalenye ye-valve ye-homogenizing. Siyibonile kathathu kulo nyaka kuphela: ukuhamba okungahambelaniyo, ukuqhekeka kwe-thermal emva kwemijikelezo ye-420, ukukhukuliseka kwesihlalo sangaphambi kwexesha kwi-cobalt-alloy nozzles. Ukusilela ngakunye kulandelelwa umva unobangela omnye—ukungonelanga kozinzo lwe-dimensional kuwo wonke amacandelo engxubevange ye-T800 ephathwa ngobushushu. Yiyo loo nto iinjineli zikhangela I-Homogenizing Valve inxalenye yomzi-mveliso Amaqabane akabuzi "Ngaba ungayenza?" Babuza "Ngaba unokubamba i-± 0.015 mm kwi-220 mm bore ngelixa ugcina ingqibelelo ye-AMS 5387 microstructure ngokukhululeka koxinzelelo lokugqibela?"
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. uphendula loo mbuzo ngoqeqesho—kungekhona izithembiso. Ngokusekwe eQingdao, inkampani isebenza kwiziko elihambelana ne-ISO apho ukuphosa, ukusetyenzwa kwe-CNC, kunye nokugqiba azikho i-handoffs elandelelanayo-ziinqanaba ezilungelelanisiweyo phantsi kwe-loop enye yokulandelela umgangatho. Xa umxhasi engenisa umzobo we-GD & T-enzima wezindlu zepiston pump cylinder, iinjineli azijongi nje ukunyamezelana. Zilinganisa iindlela zokuphazamiseka kwe-thermal, ziqinisekisa ukubola kwesanti ngokuchasene ne-gradients zokutyeba eludongeni, kunye nokuqinisekisa kwangaphambili iingozi zokungqubana kwendlela yesixhobo koomatshini bokwenyani be-5-axis-ngaphambi kokusika isinyithi sokuqala.
Iinyaniso ezintathu zobugcisa zahlula oku I-Homogenizing Valve inxalenye yomzi-mveliso ukusuka kubanikezeli benjongo ngokubanzi:
- I-Cobalt-nickel alloy mastery ayiyothiyori-iyalinganiswa. Amalungu e-AMS 5387 afumana unyango lobushushu olukwinqanaba elimbini (isisombululo se-anneal kwi-1175°C + ukuguga kwi-845°C), kunye ne-thermocouples yesithando esifakwe kwimaphu eya kwi-±1.2°C kwiindawo zomthwalo eziyi-1.8 m³. Ibhetshi nganye ifumana ukuqinisekiswa okubonakalayo-akukho "satifikethi sezinto eziphathekayo."
- Ulawulo lomgangatho luqala phambi komatshini. Ukuphoswa kwentsimbi kwiziseko zempompo zisebenzisa iinkqubo zokunyuka okupholisa ezilawulwayo ezinciphisa uxinzelelo olushiyekileyo nge-38% ngokubhekiselele kwi-gating esemgangathweni-elinganiswa nge-X-ray diffraction kwi-sample cores, engaqikelelwa.
- Umphezulu wemfezeko uhambelana nemfuno yokusebenza. Isitulo sevalvu ye-homogenizing asiyifuni i-Ra 0.4 µm kuyo yonke indawo-sifuna i-Ra 0.2 µm kwibhendi yokutywina, i-Ra 1.6 µm kumjelo we-vent, kunye noxinzelelo olulawulayo olucinezelayo lwentsalela (−320 MPa) ngaphakathi kwe-0.15 mm ubunzulu bomhlaba ongaphantsi. Oko kuphunyeziwe ngokugqitywa kwe-hybrid: ukugaya ngokuchanekileyo kulandelwa kukukroba okune-low-energy shot, kuqinisekiswe ngemicu ye-Almen kunye ne-SEM cross-section.
Abanye banokuphikisa ukuba ukudityaniswa kwe-offshore-machining-machining kumema unxibelelwano okanye izikhewu zamaxwebhu. Kodwa ngokusebenza, silandele i-17 yee-odolo zeprototype kuwo wonke uMntla Melika kunye neemarike ze-EU-kwaye lonke uphononongo lobunjineli lubandakanya ukwabelana ngesikrini sexesha lokwenyani leengxelo ze-CMM ezigutyungelwe kwiimodeli ze-CAD, ezinesitampu sexesha se-GD&T. Hayi "sizakucacisa kamva." Hayi "ngokokuqonda kwethu." Ukuqinisekiswa okubukhoma nje: "Olu tshintsho lwe-0.02 mm lokutenxa luwela ngaphandle kwenkcazo yakho-nantsi imephu yobushushu ebonisa ukuba kutheni, kwaye nantsi uyilo lwethu oluhlaziyiweyo lokuyilungisa."
Intlawulo ibonisa ekusebenzeni kwentsimi. Omnye umxhasi we-Southeast Asia utshintshe imizimba yevalvu yelifa engakwaziyo kwiiyure zokusebenza ze-14,000 kunye nenguqulo ye-QIANGSENYUAN ye-T800 yealloy. Emva kweeyure ze-28,500-phantsi kwe-290 ° C eqhubekayo, i-310-bar duty-iiyunithi zigqithise ukuhlolwa kwe-ultrasonic kunye ne-zero subsurface discontinuities. Hayi "isasebenza." Iqinisekisiwe ngokupheleleyo. Oko kuthembeka kubangelwa ukudityaniswa ngokuthe nkqo: iqela elifanayo likhetha i-cobalt ingot, iphosa into engenanto, imatshini yejometri yezibuko, kwaye ifake i-nitride coating yokugqibela. Akukho sandla sithetha ukuguquguquka okufihliweyo-akukho ukukhula okungalawulwayo okuziinkozo ngexesha lokudluliselwa phakathi kwezibonelelo, akukho ukungcoliswa komhlaba okungabhalwanga phambi kokufakwa.
Kumaqela okuthenga avavanya a I-Homogenizing Valve inxalenye yomzi-mveliso, qala ngemibuzo emithathu: Okokuqala, ngaba banokukubonisa iingxelo zovavanyo lokusila *yenombolo yakho yeodolo ethile*—hayi iicerts zegeneric? Okwesibini, ngaba iingxelo zabo zeCMM zibandakanya uvavanyo olupheleleyo lwe-GD & T (kungekhona nje "OK / NG" ukudlula / ukuhluleka)? Okwesithathu, yeyiphi inkqubo yabo ebhaliweyo yokuphatha imilinganiselo engahambelaniyo phakathi kwenkqubo-ukusebenza kwakhona, i-scrap, okanye ukuyekwa kobunjineli? QINGDAO QIANGSENYUAN ipapasha zontathu ngokwesicelo. Indlela yabo ayikho malunga nokuphepha ukusilela. Kumalunga nokubonwa kwesakhiwo kuwo onke amanqanaba-ngoko xa ukutenxa kwe-0.008 mm kubonakala kwinkqubo, kubangela ukuphononongwa kwe-metallurgical ngokukhawuleza-kungekhona isikhalazo somthengi emva kokuthunyelwa.
Ukujonga phambili, umceli mngeni awukonyusa imveliso-kukwenza nzulu ukuchaneka kokusebenza. Inqanaba elilandelayo i-R&D igxile kwiinkqubo ezixutyiweyo: imizimba yevalvu ephoswayo yotyalo-mali kunye nemijelo edibeneyo yokupholisa ngoomatshini, apho ukulinganisa okushushu kuqhuba zombini uyilo lokungunda kunye nokulandelelana kwendlela yesixhobo ye-CNC. Inqaku? Bamba i-0.01 mm cylindricity kwi-300 mm ububanzi ngaphandle kokulungiswa kwe-post-heat-treatment. Ayilophuculo olongezelelekileyo olo. Oko kuchaza kwakhona ukuba kuthetha ukuthini "ukusebenza okuphezulu" kwiivalvu ze-homogenizing-i-micron enye eqinisekisiweyo ngexesha.
