Xa iinjineli zichaza a umzi-mveliso we-valve cage, abagcini nje uku-odola iinxalenye-bakhetha iqabane elikwaziyo ukubamba ukunyamezela kwe-± 0.01 mm phantsi koxinzelelo lwe-bar ye-350, ukugcina ingqibelelo ye-microstructural emva kokunyanga kobushushu, kunye nokuhambisa ukulandelwa kwezinto ezipheleleyo ze-ASME iCandelo VIII okanye ukuthotyelwa kwe-API 6A. Leyo yinyani yokusebenza-hayi ulwimi lokuthengisa.
Sibone iiprojekthi ezininzi kakhulu zivaliwe ngenxa yokuba umthengisi "oqeqeshiweyo" akakwazanga ukubamba i-GD&T callouts kwiikheji zevalvu ye-cobalt-nickel ngexesha lokugqibela lokuqinisekiswa kwe-CMM. Enye impompo ye-OEM yaseNyakatho yaseMelika yalahlekelwa iiveki ezintandathu xa umthengisi wabo wangaphambili echaza ngokungafanelekanga iimfuno ze-AMS 5387 zesayizi-okubangelwa ukuqhekeka kwangaphambi kwexesha kwindawo yokuhlala. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha yonke ikheji yevalvu njengenkqubo esebenzayo: ukutywina umphezulu wejometri, ukuhambelana kolwandiso lwe-thermal, kunye nokuhanjiswa koxinzelelo ayizizo iinkxalabo zesibini. Zakhelwe kwipasi lokuqala lomatshini.
Indawo yethu ehambelana ne-ISO e-Qingdao iphethe ulandelelwano olupheleleyo-isanti ye-ASTM A48 Iklasi ye-35 yezindlu zentsimbi ezingwevu, i-multi-axis CNC yokugqiba iindlela zokuhamba zangaphakathi, kunye nokuphathwa kobushushu emva komatshini oqinisekisiweyo ngobulukhuni bemephu kunye nesampulu ye-metallographic. Asikhupheli ngaphandle amanyathelo abalulekileyo. Xa umenzi we-hydraulic waseYurophu efuna i-220 mm ububanzi be-piston pump cylinder housings kunye ne-42CrMo4 bores eqinile kunye nomhlaba wokutywinwa kwe-nitrided, silawule ukuhambelana kwe-metallurgical ukusuka kwi-billet eluhlaza ukuya ekupheleni komphezulu wokugqibela-akukho kuhluka kwebhetshi ukuya kwi-batch kwimeko yobunzulu okanye ubunzima obungundoqo. Oko kudityaniswa ngokuthe nkqo kuphelisa ukungaphumeleli kojongano phakathi kwe-Foundry kunye ne-handoffs yevenkile yomatshini.
Izigqibo ezithathu zobuchwephesha zahlula ukuveliswa kwecage yevalve ethembekileyo kumatshini wentengiso:
- Uqeqesho lokukhangela izinto eziphathekayo: Sisebenzisa kuphela i-cobalt-based alloys (T800, Stellite 6, AMS 5387) eqinisekisiweyo kwiingxelo zovavanyo lwe-mill kunye nokuqinisekiswa kwepropathi epheleleyo yeekhemikhali kunye nomatshini-kungekhona nje amagama ebakala kwii-invoyisi. Iqela lethu lobuchwephesha lilungelelanisa ababoneleli ngokusebenzisa i-ASTM E112 yohlalutyo lobungakanani beenkozo kunye novavanyo lwe-ASTM E384 lobunzima obuncinci kuwo wonke amacandelo.
- Inkqubo-yokuqala isicwangciso sejometri: Ngaphambi kokusika isinyithi, iinjineli zethu zilinganisa ukugqwethwa kwe-thermal ngexesha lomjikelo wokunciphisa uxinzelelo lwezindlu ezinkulu. Kuluhlu lwamva nje lwe-winch ye-offshore shaft roller, silungelelanise iindlela zezixhobo ezirhabaxa ukuze sibuyekeze i-warp eqikelelweyo ye-0.018 mm-ukuphelisa umsebenzi onokuthi ulibazise ukuhanjiswa ngeentsuku ezili-11.
- Uhlolo luzinzisiwe-alufakelwanga: Yonke i-valve cage ihlola ezintathu ze-CMM: emva kokulungiswa kakubi (ukuqinisekisa isibonelelo sesitokhwe), emva kokugqiba umatshini (i-GD & T epheleleyo), kwaye emva kokucocwa kokugqibela (ukubona umonakalo wokuphatha). I-Optical profilometry ijonga umphezulu wokutywina amaxabiso e-Ra ehla ukuya kwi-0.2 µm-ingqinwe ngokuchasene nemigangatho yereferensi ekhankanyiweyo, hayi imiqobo eqhelekileyo.
Abanye bacinga ukuba i-cobalt alloy valve cages ifuna izixhobo ezingaqhelekanga. Inyaniso kukuba, impumelelo ixhomekeke ekuphindaphindweni-hayi into entsha. Sisebenzisa izixhobo ezifanayo zokuseta kwii-HAAS VF-6 zoomatshini be-AMS 5387 imilomo, kunye nokujongwa komthwalo ophothiweyo kunye nembuyekezo yokunxiba izixhobo ezizenzekelayo. Xa umboneleli wenkonzo ye-oilfield ye-Southeast Asia eyala iiplagi ze-cobalt ze-alloy ezingama-47 ezinezihlalo ze-conical ze-12 °, safumana i-99.4% isivuno sokuqala-kungekhona ngenxa "ye-AI ephuculweyo," kodwa ngenxa yokuba abaqhubi bethu bahlaziya iingcebiso ze-probe rhoqo kwiiyure ze-8 kunye ne-log yokupholisa amanqanaba e-pH ngokutshintsha.
Iindleko azincitshiswa ngokusika iikona. Ilawulwa ngokuphelisa ukungaqiniseki. Uphononongo lwethu lobunjineli lubandakanya ingxelo yokwenziwa kokwenziwa ngaphakathi kweeyure ezingama-48: ukufaka iflegi yamacandelo anodonga olucekeceke oluthambekele ekuncokoleni, ecebisa enye iradio ukuphepha ukutshiswa kwamanqaku e-EDM, okanye ukucebisa utshintsho olucwangcisiweyo lokuphatha ukushisa ukukhusela i-warpage kwi-asymmetric geometries. Omnye umxhasi unciphise iindleko ezipheleleyo zeprojekthi nge-22% emva kokuba sicebise ukutshintshela kwi-T800 yokutyalo-mali ukuya kwi-sand-cast + echanekileyo yomatshini we-17-4PH-ngaphandle kokuphazamisa ukulinganiswa koxinzelelo.
A umzi-mveliso we-valve cage ifumana intembeko xa ithumela amaxwebhu ngenqanawa yonke indawo: iicerti zemathiriyeli, iirekhodi zokunyanga ubushushu, iingxelo zeCMM ezineentsingiselo ezitenxileyo, kunye neefoto zokuhlola ezibonwayo ezibonisa ukuthotyelwa komphezulu wokugqiba. Senza oku kuyo yonke iodolo-kunye neeprototypes. Ngenxa yokuba kwii-hydraulics zoxinzelelo oluphezulu okanye iinkqubo zokulawula i-subsea, i-cage ayiyona inxalenye. Ngumda phakathi komsebenzi kunye nokusilela.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iyaqhubeka nokucokisa iinkqubo zayo zokusahlela-machining ezixutyiweyo zesizukulwana esilandelayo seevalvu zempompo-ijolise ngokukodwa ukuhambelana komlinganiso wokuhamba okungqongqo (<±1.5%) kunye nobomi benkonzo eyandisiweyo kwiindawo ezinodaka oluludaka. Injongo ihlala ingatshintshi: ukwenza uzinzo lwe-dimensional luqikeleleke, ukusebenza kwe-metallurgical kuqinisekiswe, kunye namaxesha okuhanjiswa angenakuxoxisana.
