Xa iinjineli zichaza a umzi-mveliso wesinyithi onzima, abafuni nje enye isiseko. Bafuna iqabane eliqondayo ukuba ukunyamezela kwe-0.02 mm kwi-AMS 5387 cobalt alloy pump housing ayisicelo-yimeko engenakuxoxisana yokusinda kwenkqubo phantsi kwe-400 bar hydraulic pressure.
EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., siye saphosa saza sasebenza ngoomatshini ngaphezu kwe-12,000 yeejiyometri ezizodwa zeevalvu zehydraulic, izindlu zepiston pump cylinder, kunye ne-winch centre shaft rollers-amacandelo apho ulwahlulo lwe-microstructural okanye uxinzelelo olushiyekileyo lunokubangela ukungaphumeleli kwentsimi ngaphakathi kweeyure ezingama-300. Siye sabona abathengi betshintsha ababoneleli emva kokuba iibhetshi ezintathu ezilandelelanayo zingaphumeleli ukuqinisekiswa kwe-CMM kwi-interface ye-flange. Sikwababonile besandisa iikhontrakthi ngeminyaka emibini emva kokuba umlomo wabo wokuqala osekwe kwi-T800 cobalt uphumelele uvavanyo lokukhukuliseka komjikelo we-15,000 ngaphandle kokukhukuliseka.
Kutheni "iNgxaki" ingekho nje malunga neJometri-Imalunga noLawulo lweMetallurgical
Ubunzima bokwenyani buqala phambi kokuba ukungunda kugalelwe. Isiseko sempompo yentsimbi esantiweyo yesanti sinokujongeka silula—kodwa ukuba ibambelela kwimpompo yeoli ekude nonxweme eyi-2,000 HP, ukubalwa kwayo kwamaqhuqhuva egraphite kufuneka kuhlale phakathi kwe-120–160/mm², umxholo wayo wepearlite ≥92%, kunye nokwahluka kobulukhuni bayo kwi-1.2 m baseplate ebanjelwe kwi ±3 HBW. Elo nqanaba lokungaguquguquki lifuna ukujongwa kwe-thermal ngexesha lokwenyani ngexesha lokuqiniswa-kungekhona nje ukuhlolwa kwangemva kwenkqubo.
Sizinzisa i-thermocouples ngqo kwimingxuma yokungunda yokuphosa okubalulekileyo. Iinjineli zethu zenkqubo zilungelelanisa ubushushu obuthululwayo, uyilo lokungena, kunye nesantya sokupholisa ngokusekwe kwiiprofayile zobushushu obuphilayo-hayi iitshathi ezimileyo. Kwii-alloys ze-cobalt-nickel ezifana ne-AMS 5387, sitshisa iimbumba kwi-850 ° C kwaye sibambe imizuzu engama-90. Ukutsiba eli nyathelo kubangela i-micro-porosity kwimida yengqolowa, ethi kamva ibe ngamanqaku okuqalisa ukuqhekeka phantsi komthwalo we-cyclic.
Olu qeqesho lucacisa ukuba kutheni intsimbi yethu iphumelela ukuphinda-phinda kwe-± 0.015 mm kwiibhore ezibalulekileyo-kungekhona nje ukuchaneka-kwaye kutheni iintsimbi zethu ezingenasici zigcina i-Ra ≤0.8 µm njenge-cast kwiindawo zokutywinwa, ukuphelisa ukugaya okwesibini kwi-68% yee-odolo.
Udibaniso oluthe nkqo olunikezela ngoZinzo lweDimensional
Iivenkile ezininzi "zendawo enye" zikhupha unyango lobushushu okanye ukugqiba. Oko kudala izikhewu ze-handoff: ukuphosa kuphola ngokungafaniyo emva kokucinywa, emva koko i-warps ngexesha lokulungiswa kwe-CNC. Silawula inqanaba ngalinye-ukusuka kwirisithi yezinto ezikrwada ukuya kuvavanyo lokugqibela lokusebenza-kwindawo enye eqinisekisiweyo ye-ISO.
- Iyaphosa: Ukwenziwa kotyalo-mali kwimilomo yecobalt ebhityileyo; ukugalelwa kwesanti edityanisiweyo ngeresin kwisiseko sempompo yentsimbi enkulu ukuya kuthi ga kwi-1,800 kg
- Umatshini: I-5-axis CNC enenkqubo yokuphonononga ulungelelwaniso lwe-multi-surface (umzekelo, ukuthelekisa i-axis ye-bore ukuya kubuso obunyukayo ngaphakathi kwe-0.008 mm yokufundwa kwesalathisi)
- Unyango lobushushu: Ivacuum annealing ye T800 alloys; elawulwa-atmosphere ukuqina for martensitic stainless castings
- Ukugqiba: Electropolishing for corrosion resistance; udubule ukuchama ngenxa yokudinwa ukwandiswa kobomi kwi-winch shafts
Xa umthengi waseYurophu efuna i-cylinder ye-piston pump cylinder yezindlu ezinamatshaneli okupholisa angaphakathi kunye namazinyo egiya angaphandle, sasiqhuba ukulinganisa ukulinganisa kuqala, emva koko kuqinisekiswe ukusabalalisa ubukhulu bodonga nge-CT scanning-kungekhona nje uvavanyo lwe-ultrasonic. Kungoko sathi sayibamba indawo yomatshini. Isiphumo? Ukwamkelwa kwenqaku lokuqala kuphicotho lwe-OEM lweTier-1. Akukho kuphinda kusebenze. Akukho kulibaziseka.
Umgangatho owakhiwe ngaphakathi-awuhlolwanga
Asilindi ukuhlolwa kokugqibela ukuze sibambe imiba. Yonke ibhetshi ithwala ukulandeleka okupheleleyo: inombolo yobushushu, ingxelo yokuhlalutya inyibilika, i-ID yokuphosa iqashiso, inguqulelo yenkqubo ye-CNC, i-ID yomsebenzisi, kunye neelog zokuhlola ze-CMM-zonke zidityaniswe ngedijithali. Ukuba ivalve yoxinzelelo ayiphumeleli kuvavanyo lwe-hydrostatic, sitsala ubushushu obufanayo bezinto ezisetyenzisiweyo ekugaleleni, siphinde siqhube iimvavanyo ze-tensile, kwaye sithelekise iifoto ze-microstructure ecaleni-nge-cala kunye namaqashiso amkelwe ngaphambili.
Uhlolo lwethu olungenayo ayisiyobhokisi yokukhangela. Kwi-cobalt alloys, siqinisekisa ukuthotyelwa kwe-AMS 5387 kusetyenziswa i-OES spectroscopy-kungekhona nje iicerts ze-mill. Sijonga ubungakanani beenkozo ngokwe-ASTM E112 kwi-casting nganye yesithathu. Senza uvavanyo lokungena kwidayi kuzo zonke iindawo zokutywina ezingoomatshini-nangona zingachazwanga-kuba amava abonisa i-22% yeziphene eziqhekekileyo zomphezulu zivela kuphela emva kokunciphisa uxinzelelo komatshini.
Olu luhlu lunika iziphumo ezinokwenzeka: I-99.4% isivuno sokuqala sokupasa kumacandelo e-cobalt alloy; Imbuyekezo ye-zero ye-dimensional nonconformance ngo-2023; kunye ne-avareji yexesha eliphambili leentsuku ezili-18 zokwenziwa kweprototype-ezantsi ukusuka kwiintsuku ezingama-32 kushishino ngokubanzi.
Intsebenziswano yokwenyani iqala phambi kokuba umzobo ugqitywe
"Ungayenza lonto?" ngumbuzo wokuqala ongalunganga. Efanelekileyo ithi: "Kwenzeka ntoni ukuba sinciphisa olu ngqimba lweembambo nge-1.2 mm?" Siqhuba uphononongo lokwenziwa kokwenziwa—kungekhona njengabagcini-masango, kodwa njengabadibanisi. Sifaka iflegi kwiingxabano ze-GD&T kwangethuba: ukunyamezelana kwesikhundla kubizela i-±0.01 mm kumphezulu oyi-200 mm ubukhulu, ngelixa ukunyamezela ukubunjwa kwesiseko kuyi-±0.3 mm. Sicebisa enye indlela yokwenza idatha okanye i-engile ezihlaziyiweyo ezigcina umsebenzi kodwa zicuthe iindleko ngama-27%.
Sixhasa abathengi baseMntla Melika, eYurophu, nakumazantsi-mpuma eAsia ngencoko yobunjineli ethe ngqo-hayi ngeeleya zoguqulo. Xa umenzi wempompo waseJamani waphinda waqulunqa umzimba wabo we-valve ukuze unciphise ubunzima, sicebise ukutshintsha ukusuka kwi-316 i-stainless casting ukuya kwi-duplex 2205-i-corrosion rating rating, i-22% yamandla aphezulu esivuno, kwaye akukho mfuneko yonyango lokushisa emva kwe-weld. Bayamkela. Umyalelo wabo olandelayo waphinda kabini.
Ukuba isicelo sakho sifuna umzi-mveliso wesinyithi onzima Ikhono-hayi nje umthamo-udinga uqeqesho lwe-metallurgical, ulawulo lwenkqubo edibeneyo, kunye nokunyamezela kwe-zero ekucingeni. Udinga amaqabane aphatha yonke into ephosayo ngokungathi ibamba umva ama-400 eebha zamandla oxinzelelo lwendalo—okanye ukugcina ulwelo lokomba olukude nolwandle oluqulathwe kubunzulu bama-3,000 eemitha. Lowo ngumgangatho esiyakhela kuwo. Yonke imihla.
