Xa iinjineli zixela ukujulwa kwentsimbi engwevu kwiivalvu zehydraulic ezisebenza ngamandla okanye iimpompo zezindlu, azikhethi nje izinto eziphathekayo-zibheja ngokuzinza kwe-dimensional phantsi kwe-thermal cycling, ukuhanjiswa kweflake yegraphite engaguqukiyo kuwo wonke amaqashiso obushushu, kunye nokuthembeka komphezulu emva komatshini. Yiyo loo nto ukhetha okulungileyo inkampani yentsimbi engwevu ayithethi malunga neencwadana okanye iziqinisekiso zodwa. Kumalunga nokuziphatha okuqinisekisiweyo kwimveliso yehlabathi lokwenyani: indlela i-Foundry ephatha ngayo ukuthulula iqondo lokushisa ngexesha lokutshintsha kweyure ezingama-72, nokuba iilog zayo zedatha yokubumba isanti ziyalandeleka kwindawo nganye yokuphosa, kwaye ukuba ivenkile yayo ye-CNC inokubamba ± 0.015 mm kwi-320 mm bore-* emva * emva kokunciphisa uxinzelelo.
Siye sabona iiprojekthi ezininzi zidodobala ngenxa yokuba umboneleli uphatha intsimbi engwevu “njengentsimbi nje egayiweyo”—engahoyi ukuba umahluko omncinci wokulingana kwekhabhoni (CE), izinga lokupholisa, okanye ixesha lokushukuma lichaphazela ngokuthe ngqo ukusebenza kwebhori yesilinda okanye indawo evuzayo yokutywina. EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., intsimbi engwevu asiyonto yorhwebo. Yinkqubo ye-metallurgical elawulwayo. I-QT450-10 kunye ne-GG25 yabo iphoswa kuhlahlelo lwe-spectral *phambi kokugalelwa*, kunye ne-CE egcinwe ngaphakathi kwe-± 0.08 amanqaku kwiibhetshi. Ubushushu ngabunye buthwala ukulandeleka okugcweleyo: ilog enyibilikayo, inombolo yeladle, i-ID yomgodi wokungunda, kunye nokuqinisekiswa kobulukhuni beBrinell emva konyango-hayi nje isatifikethi esigximfizwe “siyahambelana.”
Amandla abo alele ekudibaneni ngokuthe nkqo-kungekhona njenge-buzzword, kodwa njengenkqubo yoqeqesho. Indlu yesilinda yempompo yepiston iqala njengesanti-cast-GG25 engenanto, emva koko ihambe ngokuthe ngqo kumgangatho wabo we-CNC oqinisekisiweyo we-ISO 9001 ngaphandle kokuhamba phakathi kwendawo. Akukho zimangaliso zokuphinda zibambe. Akukho lulungelelwaniso lwenkqubo lulungelelaniswa phakathi kwedatha yokuphosa kunye nesixhobo somatshini. Basebenza ngomatshini ubuso obubalulekileyo bokutywina kwiseti enye, besebenzisa izixhobo zokuphelisa izixhobo zeRenishaw ukubuyisela ubulukhuni bendawo. Yiloo ndlela abahambisa ngayo i-0.4 µm Ra ukugqiba kumhlaba wesihlalo sevalve-ngaphandle kokuqengqeleka okwesibini-kwaye bagcine i-0.02 mm yokugxila phakathi kwe-bore kunye ne-flange enyukayo kwi-120 mm ubude. Abathengi kuMntla Melika banika ingxelo nge-30% yokuvuza kwentsimi okumbalwa kwindawo yempompo yokutshintsha ngokuchasene nababoneleli bangaphambili-kuba i-microstructure ye-casting ayizange inyanzelise umatshini onobunkunkqele oveze i-porosity engaphantsi komhlaba.
Kodwa ukudibanisa kuthetha okuncinci ngaphandle kobunzulu bobugcisa ekuziphatheni kwe-alloy. Intsimbi engwevu ayibekwanga yodwa apha-yenziwe kunye neenkqubo ze-cobalt-nickel. Xa umthengi efuna i-hybrid assembly-thi, isiseko sempompo ye-GG25 kunye ne-AMS 5387 cobalt alloy alloy inserts-iqela elifanayo liphatha zombini. Bayazi ukuba i-T800 ye-thermal yokwandisa i-coefficient yi-37% ephantsi kune-iron engwevu, ngoko ke baqulunqa ukulungelelaniswa kokuphazamiseka kunye nemijikelo ethintela ukuqhekeka kwe-interfacial ngexesha lenkonzo kwi-220 ° C. Oku kutyibilika kwezinto ezinqamlezileyo kubalulekile: kuthintela ukuyilwa kwakhona okunexabiso eliphezulu xa ukungafani kwe-thermal kubangela ukusilela kwangaphambi kwexesha kwe-gasket okanye ukunxitywa okukhathazayo kwiindawo ezidityanisiweyo. Siye sabajonga ukulungelelanisa i-graphite morphology ngokusebenzisa i-inoculant timeing yokuphucula i-damping kwi-winch center shaft rollers-ukunciphisa ukuhanjiswa kwe-vibration nge-42% kwiimvavanyo zentsimi kwi-drivetrains yemoto yobunjineli.
Yintoni eyahlula kubathengisi bekhathalogu? Ixesha lokuphendula kwingxelo yokwenziwa kokwenziwa. Thumela umzobo we-GD & T-enzima womzimba wevalve yoxinzelelo, kwaye uya kufumana iiPDF ezichaziweyo kwiiyure ezingama-48-hayi amanqaku aqhelekileyo afana "nokunyamezelana okunokwenzeka," kodwa i-callouts ethile: "I-Datum C kufuneka itshintshe i-0.3 mm ibheke kwi-axis ebhorekile ukunqanda ukuphazamiseka kwevili lokugaya," okanye "Ukucacisa i-Rz endaweni yeRateation apha iphucula ngaphandle kwexabiso lokutywina." Iprotocol yomgangatho wabo ayiqhutywa kuluhlu lokutshekisha; yimaphu yomngcipheko. Imathiriyeli ekrwada engenayo ifumana uhlalutyo lokuphuma kwentlantsi *kunye novavanyo lwe-ultrasonic lokushwabana kwangaphakathi. Iitshekhi ezingaphakathi kwinkqubo zisebenzisa ii-CMM ze-Zeiss ezinesitayile se-ceramic esilinganisiweyo-hayi iintonga ze-aluminiyam-ukuze i-thermal drift ingajiki iziphumo kwi-20 ° C ambient. Ukuhlolwa kokugqibela kubandakanya uvavanyo loxinzelelo olusebenzayo kwi-1.5 × uxinzelelo lokusebenza, kunye nokuqinisekiswa kwedayi-penetrant yazo zonke iifayili ezinomatshini.
Ukuba iodolo yakho elandelayo yentsimbi engwevu ifuna okungaphezulu "kufanelekile kwaye ayiqhekeki," jonga ubungqina bolawulo lwenkqubo edibeneyo-hayi nje ukuthotyelwa. Khangela iivenkile apho i-metallurgists iphonononga iingxelo zokusasazwa kwengqolowa yesanti ngaphambi kokwenza umngundo, apho abadwelisi benkqubo be-CNC bahlengahlengisa amazinga okutya okusekwe kwimephu yobunzima bexesha langempela lokuphosa ngakunye, kwaye apho imihla yokuhanjiswa igxininiswe kwizigodo zomjikelo womlilo-hayi izithembiso zokuthengisa. Leyo yinyani yokusebenza emva kwamacandelo athembekileyo achanekileyo. Ukufaka izicelo eziyimfuneko kwi-hydraulics, i-oyile kunye negesi, okanye iinkqubo zesithuthi esinzima, oko kuhambelana akukhethi. Ngumahluko phakathi kokugcinwa okucwangcisiweyo kunye nexesha lokuphumla elingacwangciswanga.
