Xa iinjineli zichaza a umzi-mveliso wevalve yoxinzelelo, abapheleli nje ekufuneni izixhobo zekhompyutha-bakhetha iqabane elibuqondayo ubomi bokudinwa phantsi kwe-350 bar, i-thermal cycling kwiindawo ezizaliswe yi-oyile, kunye nenyaniso yokunyamezela i-dimensional drift kwi-valve seat concentricity. Sibone iiprojekthi ezininzi zilibazisekile-hayi ngeziphene zoyilo, kodwa ngokungahambelani kwesakhiwo senkozo, imijikelo yokunyanga ubushushu obungahambelaniyo, okanye ukutolika ngendlela engeyiyo kwe-GD&T ngexesha lokuphosa ukuya kumatshini ngesandla. Yiyo loo nto uthethathethwano ngokuthe ngqo nomenzi odibeneyo othe nkqo kubalulekile. Hayi inkampani yorhwebo. Hayi umthengisi onekhathalogu. A umzi-mveliso wevalve yoxinzelelo elawula i-metallurgy, machining, kunye nokuhlolwa phantsi kophahla olunye oluqinisekisiweyo lwe-ISO.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza olo hlobo lwesibonelelo-esise-Qingdao, e-China, kunye nemigca yokuvelisa ilinganiswe kwiindawo apho ± 0.01 mm "ingekho" iqinile, ayinakuxoxisana. Iivalvu zabo zoxinzelelo aziyoyunithi ye-generic off-the-shelf. Ziyinjineli kwiindibano ezisebenzayo: izindlu zepiston pump cylinder ezitywina kwibar ye-420, i-AMS 5387 i-cobalt alloy nozzles imelana nokhukuliseko kwi-high-velocity slurry flow, iiplagi ezisekelwe kwi-T800 ezisinda kwi-650 ° C kwi-cyclic exposure kwiinkqubo zokulawula i-downhole. Ezi ayizizo iinkcazo zethiyori. Silinganise ingqibelelo yomphezulu kwimizimba yabo yevalvu egqityiweyo kusetyenziswa i-interferometry yokukhanya okumhlophe-kwaye yaqinisekisa i-Ra ≤ 0.4 µm ebusweni bokutywinwa okubalulekileyo, nasemva kokunciphisa uxinzelelo.
Yintoni eyahlula oku umzi-mveliso wevalve yoxinzelelo ukusuka kwabanye yindlela abaphatha ngayo eyona ndawo inzima yenkqubo: ujongano phakathi kokusalwa nokuchaneka komatshini. Uninzi lwababoneleli abakhuphela ngaphandle okanye ukwenza oomatshini-okanye zombini. Oko kudala amanqaku amathathu okusilela: izibonelelo zokucutheka ezingahambelaniyo, i-microstructure engangqinwanga njenge-cast, kunye nokugqwetheka kwangemva komatshini kuxinzelelo olushiyekileyo. QINGDAO QIANGSENYUAN yenza zombini. Izindlu zabo zentsimbi ezenziwe ngesanti zivavanywa kwi-ultrasonic ngaphambi kokujika kwe-CNC. Amacandelo abo otyalo-mali lwe-cobalt ahlolelwa i-X-reyi *emva kokususwa kweqokobhe kodwa *phambi* konyango lobushushu—ukubamba i-microporosity kwangethuba. Emva koko umatshini we-multi-axis ulandela ulandelelwano olungqongqo lwesixhobo sokunciphisa ukwakhiwa kwe-thermal. Isiphumo? Imizimba yevalvu ene-bore-to-flange perpendicularity egcinwe ngaphakathi kwe-0.015 mm ngaphezu kwe-280 mm ubude-iqinisekisiwe nge-CMM, ayiqikelelwa.
Abanye banokuxoxa ukuba ababoneleli bendawo banikezela ngempendulo ekhawulezayo okanye unxibelelwano olulula. Inyaniso-kwii-valve zobhedu ezilula, eziphantsi koxinzelelo. Kodwa xa isicelo sakho sifuna ukuthotyelwa kwe-AMS 5387, iilog ezinyibilikayo ezinokulandeleka, okanye isiko lejometri yesiko etenxayo kwi-ISO 4401, uncedo lwengingqi luba lityala. Silandelele amava omnye we-OEM yaseMntla Melika: umboneleli wabo wangaphambili uhambise iibhetshi ezine ezilandelelanayo zevalvu yoxinzelelo lwentsimbi engenasici enobulukhuni obungahambelaniyo (248-272 HB endaweni yokuchazwa kwe-255-265 HB). Unobangela weengcambu? Ukufunxa okungalawulekiyo ixesha lokucwilisa kwiishifti. I-QINGDAO QIANGSENYUAN isombulula oku ngeeprofayili ze-thermal ezibhaliweyo, iitshathi ze-batch-specific furnace, kunye nokulandelwa kwezinto ezigcweleyo-ukusuka kwisatifikethi se-ingot ukuya kwingxelo yokugqibela yokuhlola. Ivalve nganye iphethe i-ID eyodwa edityaniswe nempahla yayo ekrwada, irekhodi yonyango lobushushu, kunye nedatha yokuskena yeCMM.
Izigqibo ezisebenzisekayo ziqala ngokucacileyo—kungekhona kwiikhathalogu. Ukuba uvavanya a umzi-mveliso wevalve yoxinzelelo, buza le mibuzo mithathu: Okokuqala, ngaba banokubonelela ngeengxelo zovavanyo lokusila eziqinisekisiweyo *kwaye* baqinisekise iipropathi zokuqina kwimveliso yakho yokwenyani-hayi isampuli nje? Okwesibini, ngaba benza uvavanyo olusebenzayo (umzekelo, ukukhangela ukuvuza kwe-bubble kwi-1.5 × uxinzelelo olusebenzayo) kwi-100% yeevalve ezigqityiweyo, okanye ukujonga indawo kuphela? Okwesithathu, uthini umyinge wabo wokuvunywa kwenqaku lokuqala kwiijiyometri ezingekho mgangathweni? Kwi-QINGDAO QIANGSENYUAN, impendulo ngu> 94%-kuba ukuhlaziywa kwezobunjineli kuqala ngaphambi kokucaphuna: Ukuqinisekiswa kwe-GD & T, impendulo yokwenziwa kwezinto, kunye nokulinganisa ukulinganisa umngcipheko wokuqina kusemgangathweni, kungekhona ukongezwa. Amandla abo akakho isikali-luqeqesho kwi-high-alloy execution. Kwaye ngumahluko phakathi kwecandelo elilingana-kunye nelinye elisebenzayo.
