Ngaba ufuna ivalve yokukhangela engayi kusilela phantsi kwe-300 bar, 450 ° C, okanye i-slurry abrasion eqhubekayo? Awukhangeli iinxalenye ze-off-the-shelf-ufuna a jonga umzi-mveliso wevalvu ngoqeqesho lwe-metallurgical, hayi nje isakhono somatshini. Siye sabona ukusilela kwenkqubo yehydraulic eninzi ibuyela emva kwingcambu enye: iivalvu ezakhelwe ukucaciswa kwekhathalogu, hayi imijikelo yoxinzelelo lwehlabathi lokwenyani. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., asenzi iivalvu zokujonga igeneric. Thina injineli amacandelo olawulo lokuqukuqela-impendulo-ukuqala kwisakhiwo sezinto eziziinkozo, hayi nje ukuzoba imilinganiselo.
Kutheni "iFactory Direct" ithetha ngaphezulu kunexabiso eliphantsi nje
“Ifektri ethe ngqo” ihlala ibonakalisa amaxesha okukhokela akhawulezayo kunye nemida engqongqo. Kodwa kwiinkqubo ze-high-integrity fluid, kuthetha into enzulu: ubunini benkqubo epheleleyo. Xa ivalve yakho yokutshekisha kufuneka itywine ngokuthembekileyo emva kwe-50,000 yemijikelo yobushushu kwimpompo yokutyibilika ekude nonxweme, awukwazi ukufikelela kwi-handoffs phakathi kwe-Foundry, ivenkile yomatshini, umthengisi wokunyanga ubushushu, kunye nomthengisi wezogquma. Siphosa, umatshini, ukuvavanya, kwaye siqinisekisa iyunithi nganye kwindawo enye ehambelana ne-ISO eQingdao-akukho manyathelo abalulekileyo angaphantsi. Yiloo ndlela esiqinisekisa ngayo ukuqhubeka kwe-microstructure kwisihlalo, idiski, kunye nojongano lomzimba. Omnye umthengi eNorway uye watshintsha iivalvu ezintathu ezingaphumelelanga kwiinyanga ezintandathu; iyunithi yabo yesine-i-AMS 5387 ingxubevange ye-cobalt, i-sand-cast + i-five-axis CNC igqityiwe-isebenze iinyanga ze-18 ngaphandle kokugcinwa. Umahluko yayingelonyamezelo-yayikukwandiswa kwe-thermal ehambelana nayo yonke indibano.
Izigqibo ezine zobuGcisa eziBalulekileyo ngokwenene (Hayi nje “iNtsimbi eNgatyiwayo”)
Ukukhetha ivalve yokutshekisha akukho malunga nokukhetha ibakala-kumalunga nokulungelelanisa izinto eziphathekayo kunye nemowudi yakho yokungaphumeleli. Nantsi into esiyiqinisekisayo ngaphambi kokuba sicaphule:
- Seat-to-disc ubulukhuni delta: Isondele kakhulu? Galling phantsi kwe vibration. Iye kude kakhulu? Micro-chipping ekuvaleni impembelelo. Kwimizimba ye-alloy esekelwe kwi-T800 ye-cobalt, sidibanisa kunye neediski ze-AMS 5737 Stellite 6-ezingqinwe 3.2x ubomi obude benkonzo ekubuyiseleni imigca yokukhupha impompo.
- Isalathiso senkozo xa sithelekisa nendlela yokuhamba: Ukuphosa kwesanti kudala ukuqina kolwalathiso. Siqhelanisa iipateni zokubumba ukuze ii-dendrites eziphambili ziqhube ngokuhambelana nokuhamba-kungekhona i-perpendicular-ukunciphisa ukhukuliseko kwindawo yokunyusa i-disc nge-41% (kulinganiswa ngemephu yobukhulu be-ultrasonic emva kweeyure ezingama-200 zovavanyo lwe-slurry e-abrasive).
- Ukulandelelana konyango lobushushu: Isisombululo se-annealing *phambi* komatshini wokugqibela kugcina ukuhanjiswa kwe-carbide kwi-cobalt-nickel alloys. Ukwenza emva kokwazisa i-micro-cracks kwi-radii ebukhali-apho ukudinwa kuqalise ukuqhekeka. Asize sitsibe eli nyathelo.
- I-GD&T esebenzayo ngaphezulu kokugqitywa kwezithambiso: Uburhabaxa bomphezulu be-Ra 0.4 µm bubalulekile kuphela ukuba buphezu komphezulu wokutywina. Sibamba i-± 0.005 mm flatness ebusweni besihlalo-kodwa vumela i-Ra 3.2 kwiiflange ezingabalulekanga. Ukongiwa kweendleko kuya ngqo ekusebenzeni, hayi ukupolisha.
Xa iikhathalogu eziMgangatho zisilela-kwaye kufuneka wenze ntoni endaweni yoko
Abanye basenokuphikisa ngelithi: “Thenga nje iivalve ezinemilinganiselo ye-ANSI B16.34—ziyavavanywa kwaye ziqinisekisiwe.” Yinyani. Kodwa ezo mvavanyo zithatha amanzi acocekileyo, ukuhamba okuzinzileyo, kunye nobushushu bendawo. Usetyenziso lokwenene alufane luthobele. Kutshanje sixhase umzi-mveliso wokukhutshwa kwetyuwa kwi-Southeast Asian apho iivalvu zokukhangela insimbi engenastainless zigrumbe kwiiveki ezisi-9—i-chloride pitting ikhawuleziswa ngokuqukuqela kwamanzi kunye nentsalela yeoksijini. Isicombululo sabo? Hayi iindonga ezityebileyo. Isiko lesanti-cast duplex yentsimbi (UNS S32205) umzimba onesitulo somatshini wejiyometri elungiselelwe ukuqukuqela okuphantsi kwakhona kozinzo-kunye nokulungiswa kweweld. Ixesha lokukhokela: iiveki ezili-11. Iindleko zizonke: 17% ngaphezulu kune-off-the-shelf. Ukufumana ixesha lokuphumla: 400% unyaka nonyaka.
Sifunda ntoni? Isiko alithethi "indleko." Kuthetha ukuphelisa iindleko ezifihlakeleyo zokutshintshwa kwangaphambi kwexesha, ixesha lokuphumla elingacwangciswanga, kunye nomonakalo wesibini kwiimpompo ezinyukayo. Uphononongo lwethu lobunjineli luqala ngeP&ID yakho, hayi iRFQ yakho. Siyabuza: Yeyiphi imeko yakho yoxinzelelo olubi kakhulu? Zingaphi ezivaliweyo ngeyure? Ngaba kukho izinto eziqinileyo ezifakiweyo? Ngaba iqela lakho lolondolozo linazo izixhobo zokulinganisa itorque kwindawo? Le mibuzo ibumba inxalenye—hayi ngenye indlela.
Ukusuka kuMzobo ukuya kuHambiso: Sikuthintela njani ukulibaziseka “kokuMmangaliso”
Iiprototypes zithunyelwa ngeentsuku ezingama-25. Ii-odolo zomthamo ophakathi (i-50-500 iipcs) zigcina i-±-3-ientsuku zokuchaneka kokuhanjiswa-kuqinisekiswe kwii-142 zokuthunyelwa kunyaka ophelileyo. Njani? Izilawuli ezizinzisiweyo ezintathu:
- Izinto zokutshixa-ngaphakathi kwinqanaba lokucaphula: Sifumana i-AMS 5387 billet eqinisekisiweyo okanye i-T800 master alloy ingots ngokuthe ngqo kwii-mills ezivunyiweyo-akukho kutshintshwa kwendawo yemarike. Inombolo nganye yobushushu ifakiwe kwaye iyalandeleka kwiingxelo zokugqibela zeCMM.
- Ukulinganisa kwangaphambili komatshini: Yonke i-contour eyinkimbinkimbi ihamba nge-VERICUT ngaphambi kokusika. Sibamba ukuphazamiseka kwesixhobo kwimizimba enodonga olucekeceke ngaphambi kokuba i-chip yokuqala ibhabha-ukuphepha ukulahlwa kwe-12,000 ye-cobalt alloy blanks.
- Ukukhutshwa kwe-Zero-batch ngaphandle kovavanyo olusebenzayo: Ivalve nganye ifumana i-hydrostatic pressure hold (1.5× rated) kunye ne-bubble-tight air test yokuvuza kwi-different yokusebenza. Akukho ngaphandle-nakwiprototypes.
Asithembisi "ukuhanjiswa okukhawulezayo." Siyathembisa unikezelo oluqikelelweyo-kuba kwiinkqubo ezibalulekileyo zobuthunywa, iintsuku ezimbini emva kwexesha zixabisa ngaphezulu kweeveki ezimbini ngaphambi koko.
Ukuba isicelo sakho esilandelayo sevalvu yokutshekisha sifuna ukuchaneka kwe-dimensional, i-metallurgical consistency, kunye nokuqinisekiswa okusebenzayo-kungekhona nje izitampu zokuthobela-qhagamshelana ne-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ngqo. Sisebenza ngokukhethekileyo koko abanye bakuphephayo: i-cobalt alloys, i-high-pressure cast cast housings, kunye neejometri ezingekho mgangathweni ezixazulula iintsilelo zokwenyani. Ndwendwela https://www.tsingtaocnc.com kwiinkcukacha zobugcisa, iziqinisekiso zezinto eziphathekayo, kunye nezalathiso zeprojekthi yokwenyani-kuquka izisombululo zevalvu yoxinzelelo ezisasazwe kuMntla Melika, eYurophu, nakuMzantsi-mpuma Asia. Umzi-mveliso wevalvu ekunene awuboneleli nje ngeenxalenye. Yabelana ngomngcipheko wakho.
