Xa iinjineli zichaza amaqabane emveliso yentsimbi engenastainless, ayikuko nje uku-odola iinxalenye-zikhusela uzinzo phantsi koxinzelelo lwe-hydraulic yeebha ezingama-300, ukuxhathisa ukubola kwindawo yegesi emuncu, kunye nokuthembeka kwe-microstructural emva konyango lobushushu. Kungenxa yoko le nto siye sabona abathengi abaphinda-phindayo abavela kwiifemu zenkonzo ye-oyile yaseMntla Melika bebuya nemizobo emitsha yempompo yezindlu kwiiveki nje ezili-12 emva kokunikezelwa kokuqala: bavavanya ukugqityezelwa komphezulu we-AMS 5387 cobalt alloy kwintshukumo yokwenyani-kwaye bafumana i-zero microcracking kwindawo yokuhlangana kwesango.
Isizathu Sokuba Indlela Yokuziphatha Yezinto Eziphathekayo Inyanzelisa Ukukhetha Kwenkqubo—Hayi Iindleko Nje
Utyalo-mali lwensimbi engenasici aluphumeleli xa amaqela ephatha njengentsimbi yekhabhoni. Siye sabukela iiprojekthi ezintathu ziphelelwa kuba abayili bakhankanye i-316L yokusaswa kwezindlu zomjikelo wepiston wempompo ephezulu ngaphandle kokubalwa kokuqina kokuqina kwe-anisotropy. Isiphumo? Iibhore ezingoomatshini zakhukuliseka nge-0.04 mm ngaphandle kwe-GD&T yokunyamezelana emva kokuthomalalisa uxinzelelo. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., inkqubo yethu iqala ngemodeli ye-thermal-ungacaphuli. Kuzo zonke izicelo zefektri yentsimbi echanekileyo, silinganisa iindlela zokuqiniswa sisebenzisa i-MAGMAsoft ukubeka iziphakamisi apho ukutya kwe-dendritic kuhlawulela ukucutheka kwendawo. Yileyo ndlela esibamba ngayo i-± 0.025 mm kwi-Ø120 mm cylinder bore IDs ngaphandle kwe-post-machining-ibaluleke kakhulu xa ubukhulu bodonga buhla ukuya kwi-8.3 mm phantsi koxinzelelo lwezibuko.
Oku akuyothiyori. Kwikota yokugqibela, imoto yobunjineli yaseJamani i-OEM yayidinga i-winch center shaft rollers kwi-17-4PH yensimbi engenasici. Umthengisi wabo wangaphambili uhambise i-12% ye-scrap ngenxa ye-interdendritic microporosity kufutshane neempiko zokupholisa. Silungelelanise igeometry yesango, sehla iqondo lobushushu lokugalela ngama-42°C, saze sazisa ukomiswa kweqokobhe elincedisa ukufunxa. Isivuno sitsibe ukuya kuma-94%. Umahluko wawungekho izixhobo ezingcono-yayiyinkqubo ye-metallurgical esetyenzisiweyo ngaphambi kokuba iphethini yokuqala ye-wax ishicilelwe.
Apho uHlanganiso oluthe nkqo luSombulula iiNdlela zokuSilela ngokwenene
Abanye ababoneleli bakhupha oomatshini ukuze banciphise iindleko. Oko kudala umngcipheko ongabonakaliyo: i-sand-cast 304 valve body can pass NDT, kodwa ke i-warp 0.08 mm ngexesha lokujika kwe-CNC ngenxa yokuba uxinzelelo olushiyekileyo aluzange lukhululeke phakathi kokuphosa kunye nomatshini. Kwiziko lethu elithobela i-ISO e-Qingdao, iqela elifanayo liphatha ukuphosa, unyango lobushushu, kunye nomatshini we-multi-axis. Silandelela yonke iqashiso ngokusebenzisa umkhondo ogcweleyo wezinto-ukuhla ukuya kwinani elinyibilikayo le-ingot ye-316L eqinisekisiweyo kunye nelogi yomjikelo wesithando somlilo wesisombululo kwi-1040 ° C ± 5 ° C.
Olu lawulo lubaluleke kakhulu kumacandelo axubileyo. Cinga ngesiseko sempompo ye-cobalt esekwe kwi-cobalt esekwe kwi-T800: iqokobhe lotyalo-mali, licocwe ngesisombululo, emva koko litshintshwe ngoomatshini be-5-axis contouring yeendawo ezinyukayo. Ukuba ukujula kunye nomatshini kwenzeka kwiindawo ezahlukeneyo, ukungafani kwembali yobushushu kubangela amandla angaguquguqukiyo e-tensile kwindawo yonke. Ukuhamba kwethu okudibeneyo kuqinisekisa amandla esivuno ahlala ngaphakathi kwe-102-108 ksi kuwo onke amakhuphoni ovavanyo-kwanakwiiyunithi ze-42 kg kunye ne-3.2 mm yamacandelo amancinci-odonga.
- Iindawo zoomatshini ze-CNC: Iibhore zokunyamezelana okuqinileyo (± 0.015 mm) kwizindlu eziqinileyo ezingenastainless
- Amacandelo e-cobalt-nickel alloy: Imilomo ye-AMS 5387 isinda kwimijikelo eyi-15,000+ kwi-450 ° C
- Ukuphoswa kwentsimbi: I-Austempered ductile iron (ADI) izithwali zegiya ezine-1,200 MPa amandla okuqina
- Iintsimbi zentsimbi kunye nentsimbi engatyiwayo: iivalvu ze-ASTM A743 CF8M ezibambe ibhari engama-200 ku-40°C
Lithetha ukuthini “isiko” ngokwenyani kumdlalo wokuSasa oPhezulu
Igama elithi "isiko" lisetyenziswa kakubi. Umzi-mveliso wokwenyani wentsimbi echanekileyo awukhupheli umzobo wakho-ucela umngeni kwiingqikelelo. Xa umenzi wempompo waseMzantsi-mpuma Asia wasithumelela umzobo wokujula we-304 wenkonzo yamanzi olwandle, uphononongo lwethu lobunjineli luphawule imiba emibini: umngcipheko we-chloride-induced pitting kwiindawo zokulungiswa kwe-weld, kunye nokungonelanga kokubekwa kwesinyusi kwi-110 mm yeflange. Sicebise ukutshintshela kwi-duplex 2205, sayila ngokutsha inkqubo yokungena, kwaye songeza isisombululo se-post-weld annealing. Ixesha lokukhokela liye landa ngeentsuku ze-5-kodwa izinga lokungaphumeleli kwintsimi liyehla ukusuka kwi-7.2% ukuya kwi-zero kwiiyunithi ze-1,200.
Siqinisekisa ukwenziwa kwezixhobo phambi kokusetyenziswa. Ukutolika kwethu kwe-GD&T kubandakanya ukujonga ukufikeleleka kwenqaku le-CMM-akukho nto imangalisayo yokwenziwa kwakhona xa inxalenye yokuqala ifika kuhlolo. Kwiijometri ezingekho mgangathweni njengeeplagi ze-cobalt alloy tapered ezinetshaneli zokupholisa zangaphakathi, siqhuba ukulinganisa, emva koko simatshini ipateni yobuchule kwi-DMG MORI NTX 1000 yethu, siqinisekisa ii-engile ezibalulekileyo nge-optical profilometry phambi kokuba ukuveliswa kweqokobhe kuqale.
Ukujonga Phambili: Apho i-Precision Casting ibhekisa khona
Umda olandelayo awukho iziko elikhulu-kukudityaniswa okuqinileyo phakathi kwe-physics yokuphosa kunye nokusebenza okusebenzayo. Sandisa i-R&D kwiinkqubo ezixutyiweyo zokwenziwa komatshini: sibeka iileya zecobalt ezinganxibiyo ngokuthe ngqo kwiisubstrates ezingenasici kusetyenziswa i-laser metal deposition, emva koko ugqibezele ngokuseta enye. Oku kuphelisa ubuthathaka bomgca we-bond kwi-cladding yendabuko. Ngaxeshanye, songeza i-ASME BPVC iCandelo VIII Div. 2 isatifikethi sokuhlangabezana neemfuno ezingqongqo zenqanawa yoxinzelelo kwiiprojekthi zamandla zaseYurophu.
Ukuba isicelo sakho sifuna insimbi engenastainless ukuchaneka kwemveliso yemveliso ephatha isinyithi njengobunjineli-kungekhona ukuthenga-ufuna amaqabane alinganisa impumelelo kuvavanyo loxinzelelo, hayi nje ukuthunyelwa ngexesha. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ihambisa iindawo ezintsonkothileyo, ezinobuthunywa-ezibalulekileyo apho ukuchaneka kwe-dimensional, ulawulo lwe-microstructure, kunye nokuthembeka okusebenzayo akuzona iinjongo ezihlukeneyo-zakhelwe kwinyathelo ngalinye lenkqubo.
