Xa iinjineli zicacisa ukuphoswa kwentsimbi echanekileyo yoxinzelelo oluphezulu lwevalvu yehydraulic okanye amacandelo empompo ye-cobalt-alloy, ayifuni nje imveliso yenkampani yokuphosa isinyithi-badinga enye ephatha uzinzo olune-dimensional njengexesha lekhontrakthi kunye ne-metallurgical consistency njengegatya elingaxoxisiyo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. luhlobo lweqabane. Ngokusekwe eQingdao, eTshayina, inkampani ayikhupheli ngaphandle kobuchule bayo obuphambili. Iphosa, oomatshini, ukuphatha ukushisa, ukuhlola, kunye neenqanawa-ukusuka kwindawo enye ehambelana ne-ISO apho zonke izindlu zevalve yoxinzelelo ziqala njenge-ingot eqinisekisiweyo ye-AMS 5387 cobalt alloy kwaye iphetha ngokuthotyelwa kwe-CMM-eqinisekisiweyo ye-GD & T ukuya kwi-± 0.01 mm.
Kutheni ubugcisa bezinto eziphathekayo buhlula ukuchaneka kokuphosa kubonelelo lwempahla yorhwebo
Siye sabona amaqela okuthengwa kwempahla elahlekelwa iiveki ezintathu-kunye ne-$ 42,000 ekusebenzeni kwakhona-kuba ibhetshi ye-alloy ye-T800 "eqinisekisiweyo" yayingenayo i-carbide dispersion. Ayingomba womatshini lowo. Kukusilela kobambiswano lwezixhobo.
I-QINGDAO QIANGSENYUAN iyakunqanda oku ngokuphuhlisa iingcombolo zemathiriyeli ekrwada kunye nababoneleli abaqinisekisiweyo. Yonke iqashiso ye-cobalt-nickel ye-AMS 5387 ifumana uqinisekiso lwe-spectrographic *phambi* kokunyibilika. Yonke i-nozzle esekwe kwi-T800 ifumana ukuqinisekiswa kwe-microstructure nge-metallografi ye-optical-hayi nje uvavanyo lobunzima. Isiphumo? Amandla okuqina aphindaphindwayo (≥1,250 MPa), ukuqina kwe-Rockwell C62-65 engaguqukiyo kuwo wonke amacandelo anqamlezileyo, kunye ne-zero batch-to-batch ye-batch kwi-coefficient yokwandisa i-thermal.
Oku akuyothiyori. Kwiprojekthi ye-oilfield yaseMntla yaseMelika yakutshanje, iplagi yabo ye-cobalt alloy ibambe i-15,000 psi kwi-280 ° C kwiinyanga ze-18 ngaphandle kwe-galling-ngelixa ababoneleli ababini abakhuphisanayo behlulekile kwiintsuku ze-90 phantsi kweemeko ezifanayo zovavanyo. Umehluko? Ulawulo lomda wokuziinkozo ngexesha lokugalela kutyalo-mali, hayi emva kokulungiswa komphezulu womatshini.
Ukudityaniswa okuthe nkqo okuphelisa ukupakisha ukunyamezela
Uninzi lwamabango “akwivenkile enye” ayawa kumdibaniso phakathi kokusakha kunye nomatshini. Izindlu ezenziwe ngesanti ziphosa ngexesha lokulungiswa kwe-CNC. Utyalo-mali luyagqwesa ngexesha lonyango lobushushu. Idimensional drift iyaphindaphinda.
QINGDAO QIANGSENYUAN kuphelisa ezo handoffs. Indawo yabo iqhuba ukuphosa utyalo-mali, umatshini we-CNC we-axis ezintandathu, unyango lobushushu be-vacuum, kunye nokugqitywa kwe-electropolished-zonke ziphantsi kophahla olunye, kwinkqubo enye yokulungelelanisa. Indlu yesilinda yepompo yepiston isuka kwipatheni yewax ukuya kwindawo egqityiweyo ngaphandle kokushiya umgangatho wemveliso. Akukho malungiselelo angaphandle. Akukho ukulungiswa kwakhona. Akukho ukukhukuliseka kwakhona.
Waba yintoni umphumo? Amabhobho e-Cylinder abamba ukungqukuva ≤0.008 mm ngaphaya kwe-320 mm ubude. Ubuso beFlange bugcina ukuhambelana phakathi kwe-0.012 mm. Kwaye i-callouts ebaluleke kakhulu ye-GD & T-efana nokunyamezela isikhundla kwimingxuma yokufaka isihlalo sevalve-iqinisekisiwe *kwinkqubo *, kungekhona nje ekuhlolweni kokugqibela.
- Iivalvu zoxinzelelo: I-ASME B16.34-ehambelanayo, kunye neerekhodi zovavanyo lwe-hydrostatic ezinokulandeleka kwinombolo yobushushu
- Iziseko zempompo: I-FEA-iqinisekisiweyo yomthwalo osebenzayo we-5x, i-santi-cast kwi-QT400-18 enemigangatho ethwele ngomatshini emhlabeni ukuya kwi-Ra 0.4 μm
- I-Winch center shaft rollers: Ngokuqina kwe-42CrMo4, umhlaba-phantsi ukuya ku-±0.005 mm ukunyamezela ukunyamezela ngaphezu kwe-1.2 m ubude.
Ulawulo lomgangatho olwakhelwe kukuhamba komsebenzi-alubotshwa emva koko
"Sihlola yonke into" ivakala iqinisekisa-ude ufunde isicwangciso sabo sokuhlola sifuna ii-17 ezibhaliweyo zokuhlola indawo nganye ye-cobalt alloy component, kubandakanywa nokuqinisekiswa kwezinto ezintathu ezihlukeneyo: i-billet engenayo, i-post-casting, kunye ne-post-heat-heat-treatment.
Yonke inxalenye ithwala ukulandeleka okugcweleyo: inombolo yobushushu, iqashiso lokuphosa, inguqulelo yenkqubo ye-CNC, i-ID yomsebenzisi, isitampu sengxelo ye-CMM, kunye nedatha yokulinganisa umphezulu. Akukho nto "yisampuli." Akukho nto "icingelwa." Ukuba umthengi ucela ukuvavanya kwakhona kwinxalenye ethunyelweyo, i-QINGDAO QIANGSENYUAN idonsa irekhodi yokuhlola yokuqala-kungekhona iphepha lesishwankathelo.
Olo qeqesho lunabela kwintsebenziswano yobunjineli. Xa i-OEM yepompo yaseYurophu ithumela imizobo enokunyamezelwa kweprofayili engaqondakaliyo kwi-cobalt alloy nozzle, iqela alizange lilinde ukucaciswa. Baqhube uphononongo lokwenziwa kwezinto, bahlohla iingxabano ezintathu ze-GD&T, ezinye iindlela zolawulo ezicetywayo ezilungelelaniswe ne-ISO 1101, kwaye babuyisela ingxelo echaziweyo kwiiyure ezingama-48-ngaphambi kokuba kuqaliswe isixhobo.
Ukukhetha umzi-mveliso wakho olandelayo wenkampani yokuphosa isinyithi kuthetha ukukhetha iprofayile yakho yomngcipheko
Iivenkile zokulahla ngexabiso eliphantsi zihambisa iinxalenye. Amaqabane achanekileyo anikezela ukuqikelela. I-QINGDAO QIANGSENYUAN isebenza ekudibaneni kwesinyithi, i-metrology, kunye nomsebenzi obalulekileyo wobuthunywa-apho ukutenxa kwe-0.02 mm ingeyiyo "ukunyamezelana okuncinci" -kukuthintelwa kokuhamba, ukuvuza kwetywina, okanye ukusilela kokudinwa okuyingozi.
Ujoliso lwabo alubanzi. Utyando: iinkqubo zehydraulic, ioyile kunye nezixhobo zegesi, iiwintshi zemoto yobunjineli, kunye neendibano zempompo ezikhethekileyo. Lo mda omxinwa wenza ukuba ulwazi lwenkqubo enzulu-njengokwazi ngokuthe ngqo ukuba i-cobalt alloy shrinkage iziphatha njani kwiindonga zotyalo-mali olubhityileyo, okanye ukuba intsimbi yesanti iphendula njani ekusikeni okuphazamisekileyo ngexesha lokugaya ubuso beflange.
Ukuba isicelo sakho sifuna ukuphinda-phinda-hayi nje ukuthotyelwa-ukuba uyilo lwakho luxhomekeke kwimfezeko ye-microstructure njengejometri, kwaye ukuba ixesha lakho lixhomekeke kwimpumelelo yokuqala, ke ilungelo imveliso yenkampani yokuphosa isinyithi ayinguye onesicatshulwa esisezantsi. Yeyona ephendulayo "Ngaba ungabamba ± 0.008 mm kwesi bhore?" kunye negophe lembuyekezo ye-thermal-kungekhona isithembiso.
