Izixhobo zetsimbi eziphosiweyo zixazulula iingxaki zehlabathi zangempela-i-hydraulic manifolds evuzayo, izindlu zempompo eziqhekekileyo phantsi koxinzelelo lwe-300-bar, i-winch shafts engaphumeleli emva kweenyanga ze-18 kwiindawo zetyuwa-spray. Ezi ayizizo iintsilelo zethiyori. Silinganise ii-microcracks kwi-AMS 5387 cobalt alloy nozzles ezibuyisiweyo kwizixhobo zokomba ezikude nonxweme. Siye sayihlengahlengisa imijikelo yonyango lobushushu emva kokubona idimensional drift kwi-T800-based piston pump cylinder housings ngexesha lovavanyo lokuhamba ngebhayisekile. Amalungu esinyithi eCast aphumelela kuphela xa i-metallurgy, ijometri, kunye noxinzelelo lwesicelo zilungelelaniswa-hayi xa i-specs ibonakala ilungile ephepheni.
Kutheni “Ukuphoswa nje” kunganelanga kwiiNkqubo eziBalulekileyo zeMishini
Uninzi lweenjineli ziyazi ukuba ukuphosa kwesanti kubamba iimilo ezinkulu. Utyalo-mali lunika unyamezelo olungqongqo. Kodwa bambalwa abaqondayo ukuba kulula kangakanani na ulungelelwaniso olugwenxa lwe-0.05 mm okanye i-2°C ukutenxa kwiqondo lobushushu eligalelayo kubangela i-porosity kwimizimba yevalvu yoxinzelelo oluphezulu. Siye sabona ukuphoswa kwentsimbi ezintathu ezifanayo-ipateni efanayo, ibhetshi enye yesiseko-eyasilela kuvavanyo lokuvuza ngenxa yokuba enye ipholile imizuzu eli-12 ngokukhawuleza kumgangatho we-shakeout. Yiyo loo nto ukuchaneka kungekho malunga nemilinganiselo yokugqibela yodwa. Imalunga nokulawula i-gradients zokuqinisa, ukufana kwesakhiwo senkozo, kunye nokusabalalisa uxinzelelo olushiyekileyo * phambi kokuba * kuqale ukusebenza.
Olo lawulo luqala ngokulandeleka kwezinto. Yonke i-cobalt-nickel alloy ingot esiyiqhubayo ithwala iingxelo zovavanyo olupheleleyo lwe-mill: amandla okuqina kwi-650 ° C, ukunyusa emva kokuphuka, ukuxhathisa ukubola kwe-intergranular nge-ASTM G28A. Akukho bhetshi iya ekugaleleni ngaphandle kokuqinisekisa umxholo wekhabhoni uhlala ngaphakathi ± 0.02% ye-AMS 5387 spec. Ngoba? Ngenxa yokuba i-0.03% yekhabhoni engaphezulu ijika i-cobalt alloy 6 ibe yi-brittle, i-crack-prone matrix phantsi komthwalo we-cyclic.
Indawo yethu ehambelana ne-ISO iqhuba ukuphosa okufanayo kunye nemigca ye-CNC-kungekhona njengamasebe ahlukeneyo, kodwa njengezigaba ezihambelanayo. Intsimbi yokuphosa ifika kwiseli yomatshini kunye noburhabaxa bayo bomphezulu owenziwe ngelaser profilometry. Inkqubo ye-CNC ilungelelanisa amazinga okutya ngokuzenzekelayo kwiindawo apho i-micro-shrinkage idala i-spikes yobulukhuni bendawo. Olu hlanganiso lunqanda ukuncokola kwesixhobo esinokuthi ngenye indlela sibeke esichengeni ukugqiba kwe-3.2 µm Ra efunekayo kumphezulu wokutywina wevalve yoxinzelelo.
Apho ukuCasa okuMgangatho kusilela khona-kwaye ukuchaneka kusitshintsha njani isiphumo
Abanye banokuphikisa ngelithi: "Ukuba iyalingana kwaye ayivuzi, kutheni uyinjineli ngaphezulu?" Kuba iindlela zokungaphumeleli zifihla kubunyani bokusebenza. Isiseko sempompo yentsimbi yomgangatho oqhelekileyo sinokubamba i-torque ngexesha lovavanyo lwefektri-kodwa ngcangcazela nge-1,750 rpm kwinkonzo yasentsimini, isantya sokuthwala nge-40%. I-iron castings yethu isebenzisa i-nodular graphite morphology elawulwa kwi-Type VI nge-ASTM A247, ukunciphisa ukuhanjiswa kwe-vibration nge-62% kuhlalutyo lwendlela yesithathu.
Ngokufanayo, "insimbi engenasici" ithetha encinci ngaphandle kokuchaza indlela yokuziphatha yebakala. I-316 engenastainless iyasilela ngokukhawuleza kulwelo olutyebileyo lwe-oyile ye-oyile. Iintsimbi zethu zensimbi ezingenasici zisebenzisa i-custom-modified 2507 super duplex-25% chromium, 7% nickel, 4% molybdenum-kunye nebhalansi yesigaba se-ferrite-austenite egcinwe kwi-45-55% nge-real-time arc monitoring ngexesha lokunyibilika. Isiphumo: zero pitting emva kweeyure ezingama-2,000 ekuvezweni kwerhasi emuncu.
Asifikeleli nje kwimigangatho-senza imaphu yokusebenza ukuze isebenze. I-AMS 5387 ingxubevange ye-cobalt ye-6 yempompo yesisombululo ingena kwi-annealing kwi-1,175 ° C ± 5 ° C, emva koko ukucima ngokukhawuleza ukutshixa ukuzinza kwesigaba se-gamma. I-Post-machining, yonke indawo ifumana ukuhlolwa kwe-fluorescent penetrant ukuze ibone ukungaqhubeki kwe-subsurface encinci kune-0.1 mm-kuba i-micro-flaw enye emqaleni we-nozzle inokutshatyalaliswa i-3 × ngokukhawuleza phantsi kwe-slurry flow abrasive.
Ezine ezingaxoxiswanga xa kufunwa iindawo zeCast Metal
Ukukhetha ababoneleli kufuna ngaphezu kokucaphula amaxesha okukhokela. Ngokusekwe kwiminyaka eli-12 exhasa ii-OEM zehydraulic kunye nabakhi bezixhobo ezingaphantsi kwamanzi, ezi ndawo zokukhangela zine zahlula amaqabane athembekileyo kubathengisi bentengiselwano:
- Izatifikethi zezinto eziphathekayo azixoxiswana-hayi nje "ihambelana ne-ASTM A48," kodwa iibhari eziqinisekisiweyo ezivavanyiweyo kwiqashiso ngalinye, kunye nolungelelwaniso lokuqina oluqinisekisiweyo kuwo wonke amacandelo okuphosa.
- Ulawulo lomda lubandakanya imeko yokuphosa-Iingxelo ze-CMM kufuneka zibonise izibonelelo zokucutheka ezisetyenzisiweyo kwiibhori ezibalulekileyo kunye nokutywinwa kobuso, kungekhona nje imilinganiselo egqityiweyo.
- Uxwebhu lwengqibelelo engaphezulu lubaluleke ngaphezu kwamanani eRa-Sifuna imifanekiso ye-SEM yemigangatho eyenziwe ngoomatshini ebonisa ukungabikho kweeleyiti ze-recast okanye ukukrazulwa kwe-micro kwiindawo ezinxibileyo eziphezulu njenge-winch center shaft rollers.
- Ukulandeleka kudlulela kwimijikelo yonyango lobushushu-Iitshati zobushushu bexesha ezifakiweyo ngokweziko ngalinye, hayi nje “ukunyangwa kobushushu ngokomlinganiselo othile.”
Xa umenzi wemoto yobunjineli yaseYurophu etshintshela kwiiplagi zethu ze-cobalt alloy, inkqubo yabo ye-winch ye-MTBF yaxhuma ukusuka kwi-4,200 ukuya kwi-11,800 iiyure zokusebenza. Akunjalo ngenxa yokuba iplagi "yayinamandla" -kodwa ngenxa yokuba inkqubo yethu yokuphosa yaphelisa i-microporosity kwi-interface ye-plug-to-housing, ukuthintela ukubola kwe-electrolytic kwiimeko ezifumileyo zetropiki.
Amalungu Entsimbi Asisiseko—Asiyongcamango Yasemva
Iisistim zomgangatho ophezulu wokusebenza ziyasilela kujongano: apho ulwakhiwo lwezindlu oludityanisiweyo ludibana neshafti eyenziwe ngoomatshini, apho ialloyi idibana netywina, apho ukwandiswa kwe-thermal kuhlangana nokulayishwa kwangaphambili kwebholiti. Amalungu entsimbi enziweyo aqinisa ezo ndawo zokusebenzela. Impumelelo yabo ixhomekeke kwizigqibo ezenziwe phambi kokuthululwa kokuqala-ukukhethwa kwezinto eziphathekayo kufakwe kwi-chemistry yamanzi, i-gating design ehambelana noguquko lobunzima bodonga, izibonelelo ze-machining ezisekelwe ekufaniseni ukulinganisa-kungekhona ukulungiswa kwe-post-cast.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha iinxalenye zetsimbi ezityhidiweyo zezicelo apho ukutshintshwa kuthetha ukuphumla okuxabisa i-$ 27,000 / iyure. Oko kunyanzelisa uqeqesho: akukho ndlela zimfutshane kungqinisiso lwesinyithi, akukho ngqikelelo malunga nonyango “oluqhelekileyo” lobushushu, akukho ukupakishwa kokunyamezela ngaphandle kocwangciso lwenkqubo eqhutywa yi-GD&T. Isiphumo? Iivalve zoxinzelelo ezisinda kwimijikelezo ye-50,000 kwi-bar ye-350, izindlu ze-cylinder zigcina i-concentricity emva kweminyaka eyi-15 yokusebenza okuqhubekayo, i-winch shafts ihambisa i-torque engaguqukiyo kwi-40 ° C kwiimeko ze-Arctic.
Ikamva lelamalungu esinyithi enziwe ngobunjineli-hayi nje ukuveliswa-ngenjongo esebenzayo ebhakwe kuyo yonke imida yeenkozo. Oko kuqala ngokubuza ukuba "Ngaba ingaphoswa?" kodwa “Imele iziphathe njani—yaye loo nto ifuna ntoni kwinyibilika, ukungunda, nakumatshini?”
