Xa ipompo ye-hydraulic ingaphumeleli phantsi koxinzelelo lwe-bar ye-350, umtyholwa unqabile ukuba itywina-okanye i-motor. Idla ngokuba yi i-alloy bushing ekhethekileyo: I-28-mm-diameter, i-sleeve ye-42-mm-ubude obunjiweyo ukusuka kwi-AMS 5387 cobalt alloy, iphathwa ngobushushu ukuya kwi-HRC 42-46, kunye noburhabaxa bomhlaba obulawulwa kwi-Ra 0.4 µm. Le nxalenye ayisebenzi nje "ifanele." Iyasinda kwibhayisekile eshushu, ixhathise inkxwaleko ngokuchasene neshafti zentsimbi eyomeleleyo, kwaye igcina ubunzulu emva kweeyure ezingama-12,000 zokusebenza ngokuqhubekayo. Bambalwa ababoneleli abanokuyihambisa—ngokuqhubekayo, ngexesha, ngokulandeleka ngokupheleleyo. Yiyo loo nto iinjineli zaseMilwaukee, eStuttgart, naseSingapore zijikela kwi i-alloy bushing factory ekhethekileyo azimiliselwanga kumabango entengiso—kodwa kuqeqesho olusekelwe kwiivenkile.
Kutheni iCobalt-Nickel Bushings isilela-kwaye kutheni iphumelele
Siye sabona iindlela ezintathu zokungaphumeleli eziphindaphindiweyo kwiindibano zempompo zoxinzelelo oluphezulu: ukuqhekeka kwe-micro-egxalabeni lokubhoboza (ukusuka kuxinzelelo olushiyekileyo), ukunxiba okukhawulezileyo kwifilim ye-oyile (ngenxa yobunzima obungahambelaniyo), kunye ne-dimensional drift ngexesha le-thermal soak (ebangelwa yi-CTE engafanelekanga phakathi kwe-bushing kunye nezindlu). Ngalinye likhomba kunobangela omnye: ukwenziwa ngamaqhekeza. Xa ukujula, ukwenziwa, kunye nonyango lobushushu lwenzeka kubo bonke abathengisi abahlukeneyo, ukuqhubeka kwe-metallurgical kuyophuka. Ukutya okuziinkozo kuyaphazamiseka. Umphezulu wengqibelelo uyasokola. Ukunyamezelwa kwemfumba ngokungalindelekanga.
E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Inkqubo ihlala phantsi kophahla olunye. Indawo yabo ehambelana ne-ISO iphatha utyalo-mali lwe-T800-based alloys cobalt, emva koko yenza i-CNC ye-axis emihlanu yokujika kunye nokusila kwangaphakathi-konke ngaphandle kokususa inxalenye kwindawo yayo. Oku kuphelisa iimpazamo zokuphinda kulungiswe kwaye kugcinwe imbali ye-thermal. Ibhetshi yakutsha nje ye-AMS 5387 bushings yempompo yodaka ekude nonxweme ibonise ±0.008 mm ukungqukuva okungaphezulu kwe-40 mm ubude-kulinganiswa kwi-Zeiss CONTURA G2 CMM, kunye ne-material certs elandelekayo kwi-mill lot #COB-22894A.
Izakhono ezine ezingaxoxisiyo ongenakukwazi ukuzikhupha ngaphandle
Yinyani i-alloy bushing factory ekhethekileyo kufuneka ihambise ngaphezulu kokuthotyelwa komda. Kufuneka iqinisekise ukusebenza okusebenzayo-ngaphambi kokuba inxalenye yokuqala yeenqanawa. Oko kufuna izinto ezine ezidityanisiweyo:
- Ubugosa ngezinto eziphathekayo: Hayi nje ukufumana i-AMS 5387 okanye i-T800-kodwa ngokubambisana nokuphuhlisa imijikelo yokunyanga ukushisa kunye nabanikezeli be-alloy ukuzinzisa ukusasazeka kwe-carbide
- Inkqubo yokudibanisa: Machining parameters alungelelaniswe njengoko-cast microstructure-hayi generic feeds kunye nezantya
- Ubunzulu bokuhlola: I-CMM iskena kumanqaku angama-300+ ngenxalenye nganye, kunye novavanyo lwe-ultrasonic ye-subsurface porosity, kunye nokuqinisekiswa okubonakalayo phantsi kwe-10× magnification
- GD&T ngobuchule: Iinjineli ezitolika i-ASME Y14.5 callouts njenge "datum B ethathwe kumphezulu wokulahlwa" ngaphandle kokucela ukuyilwa ngokutsha
Omnye umthengi uphinde wayila indlu yesilinda yepompo yepiston emva kweprototypes ezintathu ezingaphumelelanga kwenye indawo. Iqela le-QINGDAO QIANGSENYUAN libonise ukuba ukunyamezela kwe-0.01 mm okuchaziweyo kwi-bushing bore kwakungafezeki * ngaphandle kokuguqula i-angle yedrafti yokuphosa *. Bacebise ukunyamezela kwe-0.025 mm kunye ne-callout elawulwayo yokugijima-kwaye bahambisa imvume yenqaku lokuqala kwiintsuku ze-11.
Oko Kuthethwa “Isithethe” Ngokwenene—Ngaphaya Komzobo
"I-non-standard" ayisiyiyo into yokubambisa yonke into yobunjineli. Kukuzibophelela kwinjongo esebenzayo. Xa umxhasi wase-Asia-mpuma efuna i-bushings ye-winch center shaft rollers esebenza kwindawo yokutshiza ityuwa, abazange bachaze nje intsimbi engenasici. Bafuna ukuxhathisa kwi-crevice corrosion kwi-85 ° C, umthamo womthwalo we-185 kN, kunye ne-coefficient of friction phantsi kwe-0.08 ngokuchasene ne-nitrided 42CrMo4. I-QINGDAO QIANGSENYUAN iphendule nge-duplex casting: umaleko wangaphandle we-ASTM A995 Gr. I-4A (i-super duplex stainless), i-liner yangaphakathi ye-cobalt-nickel alloy, idityaniswe nge-HIP bonding. Isiphumo siphumelele uvavanyo lwenkungu yetyuwa yeeyure ezingama-2,000 nge-zero pitting-ngelixa usika ubunzima nge-17% ngokuchasene ne-cobalt eqinile.
Oku akuyiyo iprototyping. Kukusonjululwa kwengxaki yomgangatho wemveliso-apho zonke izigqibo zinxibelelana nokuziphatha kwentsimi: ukunyibilika kwe-vibration, ukungahambelani kokwanda kwe-thermal, ukuhambelana kwe-lubricant, ukuqikelela ubomi benkonzo.
Umda Olandelayo: Iinkqubo zeHybrid, hayi Amacandelo nje
Ikamva leebhutsi ezisebenza kakhulu lilele apho ukuchaneka kokuphosa kuhlangana nokuthembeka komatshini. I-QINGDAO QIANGSENYUAN ngoku iyinkqubo elungeleleneyo yotyalo-mali: utyalo-mali olusondele kwimilo enemijelo yokupholisa edibeneyo, egqitywe ngomatshini we-electrochemical machining ukuya ku-Ra 0.1 µm umphezulu wokugqiba—akukho manqaku esixhobo, akukho umaleko wokuphinda udlale. Ezi ayizozinto zaselebhu. Zisekungqinisisweni kweevalvu zolawulo lwe-subsea elandelayo ezifuna ukuvuza kwe-zero kwi-1,200 bar.
Ukuba isicelo sakho sifuna i-bushings engahlangani nje ne-specs-kodwa yandisa ubomi benkqubo, ukunciphisa amaxesha okugcinwa, kwaye uphile ngaphaya kobomi boyilo ... jonga iikhathalogu ezidlulileyo kunye neziqinisekiso. Jonga umgangatho wevenkile apho i-metallurgists kunye noomatshini babelana ngeshedyuli efanayo yokutshintsha. Kulapho uya kufumana a i-alloy bushing factory ekhethekileyo kufanelekile ukuchazwa.
