Xa iinjineli zicacisa icandelo leenkqubo zoxinzelelo oluphezulu lwe-hydraulic okanye iindibano zempompo ye-oilfield, azifuni nje isinyithi-ziyayidinga. i-metallurgy eqikelelwayo, uzinzo oluphinda-phindayo lwe-dimensional, kwaye unyamezelo lwe-zero lokungahambelani kwe-microstructural. Yiyo loo nto ukukhangela kwinyani utyalo-mali lokugalela i-alloy factory ayilonyathelo lokuthenga-sisigqibo sokunciphisa umngcipheko.
Kutheni "i-alloy" ibaluleke ngaphezu "kokuphosa" wedwa
Uninzi lwabaseki baphosa intsimbi okanye intsimbi yekhabhoni. Bambalwa abaphatha ii-cobalt-nickel superalloys ezifana ne-AMS 5387 okanye izixhobo ze-T800-grade ngaphandle kokuqhekeka, ukulwa, okanye ukwahlula iinkozo. Siye sabona iindawo ezintathu zokungaphumeleli eziqhelekileyo kwiintambo zokubonelela ngehlabathi: okokuqala, ukunyangwa kobushushu obungahambelaniyo emva kokuphosa utyalo-mali-okukhokelela kwi-12-18% ukuhluka kwi-Rockwell C ubunzima kwiibhetshi; okwesibini, ukutshisa okungonelanga kweqokobhe leceramic kubangela ukubandakanywa kweoksidi yomphezulu kwindawo yokutywina ebalulekileyo; okwesithathu, post-cast machining esusa kufutshane-net-shape imfezeko inkqubo kwakuthetha ukuhambisa.
Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke ingxubevange ye-cobalt ye-alloy, yonke i-AMS 5387 yezindlu zepompo, kunye neplagi nganye esekelwe kwi-T800 iqala nge-traceability yezinto ekrwada eqinisekisiweyo-ingeyiyo nje amanani amaninzi, kodwa iingxelo ezipheleleyo zovavanyo lokusila ziqinisekisiwe ngokuchasene ne-ASTM E1476 kunye ne-ISO 9000 ye-A.01501. Akukho kutshintshwa. I-alloy ichaza isilingi yokusebenza; inkqubo yokuphosa kufuneka igcinwe.
Ukudityaniswa okuthe nkqo akusiyo i-Buzzword-yiNdawo yokulawula
Awunakuqinisekisa ± 0.015 mm ukungqukuva kwi-piston pump cylinder yezindlu ukuba ukuphosa, unyango lobushushu, kunye ne-5-axis CNC ukugqiba kwenzeka kwizibonelelo ezahlukeneyo. Imbali yobushushu iyalahleka. Datum iimbekiselo shift. Iinkcazo zokugqiba umphezulu ziyakhukuliseka.
Yiyo loo nto indawo yethu ye-Qingdao isebenza njengokuhamba komsebenzi omnye okuqhubekayo: utyalo-mali → ukulawula umoya-moya → ukunciphisa uxinzelelo → ukujika okuchanekileyo kunye nokugaya → uhlolo olungonakalisi (UT + ukungena kwedayi) → ukuqinisekiswa kokugqibela kweCMM ngokuchasene ne-GD&T callouts. Umzekelo, iiroli ze-winch yemoto ye-winch centre shaft zivavanywa ngokupheleleyo *emva* kokusila okokugqibela-hayi ngaphambili. Ngenxa yokuba ukungalingani akukho malunga nobunzima bodwa; imalunga nendlela uxinzelelo olushiyekileyo olusebenzisana ngayo nomthwalo we-centrifugal kwi-3,200 RPM.
Oku akuyothiyori. Enye ye-OEM yaseMntla yaseMelika yanciphisa ukungaphumeleli kwentsimi nge-67% emva kokutshintsha ukusuka kwikhonkco lomthengisi we-multi-tier kwisisombululo sethu somthombo omnye wemizimba ye-valve yoxinzelelo-ngokukodwa ngenxa yokuba silawula yonke indlela ye-thermal-mechanical ukusuka kwipatheni ye-wax ukuya kuvavanyo olusebenzayo.
Ukuchaneka kweLizwe lokwenyani kufuna uQinisekiso lweLizwe lokwenyani
"Ukuchaneka okuphezulu" kuthetha izinto ezahlukeneyo kubasebenzisi abohlukeneyo. Kumyili wempompo, kukugxila phakathi kobuso kunye ne-flange phantsi kwe-0.02 mm TIR. Kwinjineli ye-corrosion, buburhabaxa bomphezulu u-Ra ≤ 0.8 µm *emva* kwe-passivation-akukho kuphinda kuvunyelwe. Kwiqela lolondolozo, kukutshintshiselana kuyo yonke iminyaka emihlanu yemveliso ngaphandle kokuhlaziya izixhobo.
Siqinisekisa zontathu-ngamaxesha onke. Iibhilethi ze-cobalt alloy ezingenayo zifumana uhlalutyo lwe-spectrographic. Ubungakanani benkqubo buqinisekiswa kusetyenziswa iZeiss CONTURA G2 CMMs zilinganiswe yonke imihla. Amacandelo okugqibela afumana uvavanyo loxinzelelo olusebenzayo kwi-1.5 × inqanaba loxinzelelo lokusebenza, kunye nexesha langempela lokubeka iliso lokuvuza ukuya kuthi ga kwi-10.−6 mbar·L/s. Kwaye ewe-sigcina umkhondo ogcweleyo wedijithali: yeyiphi ibhetshi yesithando somlilo, nguwuphi na umqhubi, yeyiphi inguqulelo yenkqubo yeCMM, yeyiphi inombolo epholisayo. Ukuba kukho into engaphumeleliyo enkonzweni, siyazi kakuhle apho sijonge khona.
Abathengi bahlala bebuza: "Ngaba ungabamba indawo yokwenyani ngaphakathi kwe-0.025 mm kwi-flange ye-320 mm ye-diameter enemingxuma eli-12?" Ewe-ukuba umzobo ubandakanya iithagethi zedatum, inkcazo yemathiriyeli, kunye nenjongo yokusebenza. Kodwa siza kukuxelela kwangaphambili ukuba i-GD&T icaciswe ngaphezulu kwesicelo, okanye ukuba enye indlela yokuphosa isanti ingahlangabezana nokusebenza ngexabiso eliphantsi ngama-40%. Ukungafihli akungomgaqo-nkqubo. Luqeqesho lobunjineli.
Apho Ukuchaneka Kudibana neNtsebenziswano
An utyalo-mali lokugalela i-alloy factory kufuneka yenze okungakumbi kunokuhambisa iinxalenye. Kufuneka ikuncede uphephe imijikelo yohlengahlengiso, ukubaleka kwezinto ezilahliweyo, kunye nokulibaziseka kwesiqinisekiso senqanaba kade. Yiyo loo nto inkxaso yethu yeprojekthi iqala phambi kwePO: ukuphononongwa komzobo kunye nengxelo yokwenziwa kwezinto, iinketho zokutshintsha izinto ezixhaswa yidatha ye-tensile / creep, kunye namaxesha okukhokelela kwiprototype phantsi kweentsuku ezingama-21 kwiialloys ezifanelekileyo.
Sisebenzela abadibanisi benkqubo yoxinzelelo lwehydraulic eJamani, abakhi bezixhobo ze-subsea eNorway, kunye nabavelisi bempompo enzima kuwo wonke uMzantsi-mpuma Asia-hayi ngabasasazi, kodwa ngokuzibandakanya ngokuthe ngqo kobugcisa. Kuba xa iinkcukacha zakho zibiza i-AMS 5387 ene-HRC 42–46 kunye nokumelana nokutyiwa kwe-intergranular ngokwe-ASTM A262 Practice E, iinkcazo zesakhono segeneric aziyi kuyinqumla. Udinga amava aqinisekisiweyo ngelo bakala lichanekileyo, phantsi kwezo meko zichanekileyo.
Xa sijonge phambili, sandisa i-R&D yethu yokwenziwa komatshini—ingakumbi kwiindonga ezicekethekileyo, ezinomlinganiselo ophezulu apho utyalo-mali lwemveli lufikelela kumda. Kodwa eyona nto iphambili kugxininiso lwethu ayitshintshi: ukuhambisa izinto ezintsonkothileyo, ezinobuthunywa zentsimbi apho ukuchaneka komgangatho, imfezeko ye-microstructural, kunye nokuthembeka okusebenzayo ayilulo urhwebo. Azinakuxoxisana.
