I-Stellite 21 ayisiyiyo enye i-alloy esekwe kwi-cobalt-ziinjineli zezinto eziphathekayo ezifikelelayo xa ukungaphumeleli kungeyona inketho. Ubushushu obuphezulu be-corrosion, i-abrasive slurry, i-cyclic pressure spikes: ezi ayizomeko ezisecaleni kwiimpompo ze-hydraulic okanye imizimba yevalvu yendawo yeoli. Ziimeko zokusebenza zemihla ngemihla. Kwaye kwezo ndawo, i-Stellite 21 ihambisa ukuxhathisa okunokulinganiswa, ukuzinza kwe-microstructural, kunye nokuxhathisa i-galling apho iintsimbi eziqhelekileyo ezingenastainless okanye i-Inconel 625 iwa mfutshane.
Kodwa ukufumana iStellite 21 ayikokufumana * nawuphi na umthengisi. Imalunga nokufumana a Umzi-mveliso weStellite 21 ephatha i-metallurgy njengobunjineli-hayi ulungiselelo. Sibone iiprojekthi ezininzi zilibaziseka ngenxa yobunzima obungahambelaniyo (HV 380–450 uluhlu lokukhukuliseka kwiibhetshi), ukungazinzi komgangatho emva konyango lobushushu, okanye ukugqiba komphezulu okusilelayo kwiimfuno zokutywinwa. Ezo ntsilelo azifane zivele kwi-alloy ngokwayo. Baphuma kwiinkqubo eziqhekekileyo: ukwenziwa kwemveliso kude nonxweme, ukwenziwa komatshini kwiivenkile zemisebenzi ngokubanzi, akukho mkhondo phakathi koqinisekiso lwebillet ekrwada kunye nengxelo yokugqibela yeCMM.
Kutheni i-"Factory Direct" itshintsha iZiphumo zeHlabathi zokwenyani
E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., “ifektri ethe ngqo” ithetha ulawulo olupheleleyo kwizigaba ezine ezingaxoxisiyo: ukuthathwa kwemathiriyeli ekrwada eqinisekisiweyo ye-AMS 5387, utyalo-mali oluchanekileyo lwejiyometri entsonkothileyo njengemibhobho yempompo kunye nezihlalo zevalvu, i-multi-axis CNC procession kunye nokuhlola inkqubo yoxinzelelo lwe-CNC lokugqibela. GD&T callouts-hayi ukunyamezelana generic. Asithengisi kwakhona. Sivelisa.
Oku kudityaniswa ngokuthe nkqo kusombulula iindawo ezintathu zentlungu eziqinisekisiweyo:
- I-Dimensional drift kwi-high-aspect-retiyo components: Izindlu zepiston pump cylinder esizenze ngomatshini kwikota yokugqibela zibambe ±0.015 mm concentricity ngaphaya kwe-280 mm ubude—kuba ukucutha ukucutha kuye kwenziwa imodeli kwaye kwabuyiswa phambi kokuveliswa kwendlela yesixhobo, ayilungiswanga emva komatshini.
- Ukwakhiwa kwe-Microcrack kwiindawo ezichaphazelekayo kubushushu: Iiplagi zethu ze-T800-alloy zenze isisombululo kwi-1180 ° C ± 5 ° C, elandelwa ukupholisa okulawulwayo-kungekhona ukucima isithando somlilo-kuqinisekiswe nge-ASTM E112 uhlalutyo lobungakanani bengqolowa.
- Ukungafani komgangatho wemfezeko: Xa umthengi waseYurophu efuna i-Ra ≤0.4 µm kwindawo yokuhlala ye-cobalt-alloy ukuze ihambelane ne-elastomer, iprotocol yethu yokugqiba yayiquka i-vibratory deburring, i-electrochemical polishing, kunye ne-white-light interferometry verification-kungekhona nje ukudlula okubonakalayo / ukungaphumeleli.
Zeziphi “Izisombululo Zengxubevange Esebenza Kakhulu” Ezizisayo—Hayi Izithembiso Kuphela
Abanye ababoneleli badwelisa iStellite 21 kwikhathalogu yabo kwaye bamise apho. Siyiphatha njengenkqubo. Onke amacandelo esiwathumelayo anobungqina obubhaliweyo: iingxelo zovavanyo lokusila ezihambelana ne-AMS 5732 imida yeekhemikhali, ubulukhuni beemephu ezibonisa ukuhambelana kwe-HV kubuso obunxibileyo obubalulekileyo, kunye nokulandeleka okugcweleyo ukusuka kwinani lobushushu le-ingot ukuya kwileyibhile yokupakisha yokugqibela. Akukho ngaphandle-nakwiprototypes.
Siyazi nokuba yintoni iStellite 21 * ayisombululi *. Ayizukulungisa uyilo olubi lwe-hydraulic. Ayiyi kuhlawulela i-shafts engafanelekanga okanye i-rotors engalinganiyo. Ngoko uphononongo lwethu lobunjineli luqala kwangethuba: sifaka iflegi ye-GD & T yokungqubuzana ngaphambi kokusika isinyithi, sicebisa uhlengahlengiso lwe-radii ukunciphisa uxinzelelo loxinzelelo kwizicelo zomjikelo ophezulu, kwaye siqinisekise ukuba isisombululo se-cobalt-nickel siyimfuneko ngokwenene-okanye ukuba i-17-4PH enzima kunye ne-nitriding ephuculweyo ingazisa ubomi obulinganayo benkonzo ngexabiso eliphantsi.
Olo qeqesho lubonakaliswa kukusasazwa kokwenyani. Esinye isixhobo sendawo yeoli yaseMntla Melika iOEM yatshintsha izikhondo zevalve eziyi-4140 kunye neenguqulelo zethu zeStellite ezingama-21. Ixesha eliphakathi phakathi kokusilela litsibe ukusuka kwi-42,000 ukuya kwi-117,000 yeeyure zokusebenza. Akunjalo ngenxa yokuba i-alloy inomlingo-kodwa ngenxa yokuba yonke inkqubo-ukusuka kuyilo lokungunda kwesanti ukuya kuvavanyo lokugqibela lwe-ultrasonic-yenziwe malunga nokusebenza komsebenzi, kungekhona nje ukuthotyelwa kwezinto eziphathekayo.
Indlela yokuqinisekisa iFactory yeStellite eyiNyaniso-Ngaphaya kweWebhusayithi
Buza le mibuzo mithathu ngaphambi kokuba wenze:
- Ngaba unokubonelela ngesatifikethi sebhetshi yakutshanje ebonisa umxholo wekhabhoni ≤0.25%, i-chromium ≥27.5%, kunye ne-tungsten ≥13.5%-zonke ziqinisekiswe yi-OES spectroscopy, kungekhona nje iingxelo zokugaya?
- Ngaba wenza i-post-machining i-residual stress measurement kumalungu angaphezu kwe-150 mm kuwo nawuphi na umlinganiselo-kwaye ulungise unyango lobushushu ngokufanelekileyo?
- Ngaba i-ISO 9001:2015 yakho isimbo idweliswe ngokucacileyo ukuquka "ukusatywa kunye nokulungiswa kweealloyi ze-cobalt-chromium," okanye ngaba "zikhomponi zentsimbi" eziqhelekileyo?
Ukuba iimpendulo azicacanga, zilibazisekile, okanye zifuna ukuhanjiswa komntu wesithathu-uthetha nomsasazi, hayi Umzi-mveliso weStellite 21. Kwi-QINGDAO QIANGSENYUAN, loo maxwebhu aveliswa ngaphakathi, ahlaziywa yi-metallurgists, kwaye abelane ngeeyure ze-48 zesicelo.
Ukusebenza kweStellite 21 akuyothiyori. Ilinganiselwa kwiiyure zokusebenza okungaphazamisekiyo, ii-microns zelahleko yokunxiba kwimijikelo yesigidi, kunye nembuyekezo ye-zero yentsimi kwiindibano zempompo ezibalulekileyo kubuthunywa. Oko kuthembeka akuqali ngedatha ye-alloy-kodwa ngubani olawula isithando somlilo, inkqubo ye-CNC, kunye neprotocol yokuhlola yokugqibela. Kwiinjineli ezichaza iindawo apho ixesha lokuphumla lixabisa i-$ 12,000 / iyure, loo mahluko awukho iinkcukacha. Ngumahluko phakathi kokuqinisekiswa kweshedyuli kunye nokucwangcisa okunokwenzeka.
