Ukuphoswa kwensimbi engenasici kwifektri yezixhobo zamandla kudinga okungaphezulu nje kokuchasa ukubola-zifuna uzinzo lwe-dimensional phantsi kwebhayisikile ye-thermal, imfezeko ye-microstructural kwi-400 ° C +, kunye nokunyamezela kwe-porosity kwiindawo ezinoxinzelelo oluphezulu. Siye sabona izindlu ezintathu ezisileleyo zevalve ye-injini yomoya zibuyile kwisikhululo samandla saseMzantsi-mpuma Asia ngenxa yokuba isiseko silutsibe uvavanyo lwe-ultrasonic kwisango le-weld zone. Yingakho ukucacisa ukuchithwa kwensimbi engenasici kwifektri yezixhobo zamandla kuthetha ukulungelelanisa isayensi yezinto eziphathekayo, ukulawulwa kwenkqubo yokuphosa, kunye nokuqinisekiswa okusebenzayo-kungekhona nje ukuphawula ibhokisi yebakala njenge "CF8M".
Kutheni uTyalo-mali loTyalo-mali lubetha iSanti yeSanti kwiiNgxelo zaMandla aBalulekileyo
Ayizizo zonke iintsimbi zetsimbi ezenza ngokulinganayo phantsi koxinzelelo lwe-thermal cyclic. Kwiinyanga zethu zokugqibela ze-18 zempompo yemveliso yezindlu zempompo ye-oyile ye-offshore kunye nabathengi begesi, utyalo-mali olufakwe kwi-316L lwamacandelo lubonise i-42% yee-microcracks ezimbalwa emva komjikelezo we-5,000 woxinzelelo ngokuchasene neendawo ezilinganayo zesanti. Ngoba? Ukwenziwa kotyalo-mali kuzisa unyamezelo olungqongqo (±0.3 mm vs ±1.2 mm), ukugqiba komphezulu ocolekileyo (Ra 3.2 µm vs Ra 12.5 µm), kunye nokulingana okuziinkozo okugqwesileyo-kubalulekile xa inxalenye yakho ibambelela impompo yebhoyila enentloko ephezulu ehamba kwibhari engama-220.
Ukuchithwa kwesanti kuhlala kusebenza kwiziseko ezinkulu, ezinoxinzelelo oluphantsi-ezifana neziseko zempompo okanye izakhelo zenkxaso yeinjini yomoya-apho ubunzima kunye neendleko zilawula. Kodwa kwiindibano ezijikelezayo, imizimba yevalvu, okanye izindlu zomgibe womphunga, ukuphosa utyalo-mali akunakuxoxwa. Siqinisekisa ibhetshi nganye ngohlalutyo lwe-spectral, uvavanyo lwe-tensile nge-ASTM A743, kunye nokuhlolwa kwe-radiographic kwi-ASME BPVC iCandelo V. Akukho ngaphandle.
Ukukhethwa kwezinto eziphathekayo akukhona nje ngamaNani eBanga
"316 stainless" ayikuxeleli nto malunga nokusebenza kwehlabathi lokwenyani. Sibuza imibuzo emithathu ngaphambi kokucaphula: Yintoni ubushushu bokusebenza okuphezulu? Ngaba i-chloride ikhona-nakwi-5 ppm? Ngaba icandelo lifumana ukudinwa koomatshini okanye umthwalo nje omileyo?
- Ngeevalvu zecondenser ezipholiswe ngamanzi olwandle: Sicacisa i-F44 (UNS S32750) i-duplex enkulu-hayi i-316-kuba i-PREN yayo> i-40 iyaxhathisa i-pitting apho i-chlorides igxininise kwimingxuma.
- Kwiimpompo ze-geothermal brine: I-ASTM A995 Gr. I-6A (CD4MCu) iphatha i-H₂S + CO₂ ngcono kunamabakala e-duplex asemgangathweni ngenxa yebhalansi ye-ferrite / austenite elawulwayo.
- Ngenkonzo yenyukliya: Ukwenziwa kwe-CF3M kujongwa kwisisombululo esigcweleyo + sokucinywa ngokwe-ASTM A351, emva koko kuvavanywa umhlwa phakathi kwegranular ngokwe-ASTM A262 Practice E.
Siyala amaqashiso ezinto ezikrwada ngaphandle kweengxelo zovavanyo lokusila ezibonisa izinto zomkhondo-ingakumbi isulfure (<0.015%) kunye neoksijini (<0.002%). Ixesha lokuphumla lomnye umthengi weenyanga ezili-12 libuyele emva kwisulfure ephakamileyo ebangela ukukrazuka okushushu ngexesha lokwenziwa komatshini wokugqibela. Eso sifundo satshintsha inkqubo yethu yokuhlola engenayo-kunye neyabo.
Ukudityaniswa okuthe nkqo kuSombulula iiNdawo zeNzululwazi zoMveliso wangempela
Uninzi lweentsilelo azenzeki ekusalweni-kodwa kujongano phakathi kokusalwa kunye nomatshini. Umzimba wevalve yesanti unokudlula i-NDT, kodwa i-warp 0.15 mm ngexesha lokusila i-CNC ngenxa yoxinzelelo olushiyekileyo. Sisusa loo mngcipheko ngokulawula ikhonkco eligcweleyo: ukuphosa → unyango lobushushu lokunciphisa uxinzelelo → ukwenza amatshijolo arhabaxa → ukuguga → ukugqibezela umatshini → uqinisekiso lweCMM.
Indawo yethu ehambelana ne-ISO iqhuba olu landelelwano phantsi kophahla olunye. Silinganisa yonke into ebalulekileyo ngeegeyiji zomoya ezilinganisiweyo yonke imihla; qinisekisa ukujula kwezikhondo zevalvu usebenzisa izithelekisi zokukhanya; kunye nokuqina komphezulu wemephu kuzo zonke iindawo eziphathwe ubushushu kunye nabavavanyi abaphathwayo beRockwell. Xa umxhasi waseYurophu wayedinga izindlu ezingama-48 zerhuluneli yomoya efanayo eziziswe kwiiveki ezili-11, sakha iipateni, sagalela, sasebenza ngoomatshini, saza savavanywa—zonke zingaphakathi endlwini. Akukho handoffs. Akukho lunxibelelwano. Akukho ziliphu zeshedyuli.
Oku akukho lula-yi-physics. Ukwenza umatshini wokuphosa ngaphandle kokwazi usasazo loxinzelelo lokuphoswa kufana nokulungisa i-injini evale amehlo.
Eyona nto uyifunayo ngaphambi kokubeka iodolo yakho yokuqala
Ungasithumeli ifayile yeCAD kwaye ulindele ukucaphuna. Zisa ezi zinto zine kuphononongo lobunjineli:
- Umzobo ophawulweyo oqaqambisa i-GD&T callouts echaphazela umsebenzi-hayi nje ubuhle.
- Idatha yendawo yokusebenza: ubushushu obuphezulu/umzuzu, ikhemistri yolwelo (ene-pH, ikloridi, amanqanaba e-H₂S), kunye nomjikelo womsebenzi (oqhubekayo vs intermittent).
- Iimfuno zokuvavanya: uxinzelelo lwe-hydrotest, indlela ye-NDT (RT / UT / PT), kunye neendlela zokumkela (umzekelo, "akukho zibonakaliso> 1.5 mm ubude").
- Iimfuno zokulandeleka: Ngaba ufuna ukulandeleka okugcweleyo kwinani lobushushu? Izatifikethi zezinto eziphathekayo nge-EN 10204 3.1 okanye 3.2?
Siza kuphendula kwiiyure ze-48 ngeempendulo zokwenziwa-kuquka iingcebiso ezifana nokufudusa icandelo elincinci lodonga ukuze ugweme ukuncipha okanye ukongeza i-angle eyidrafti yokunciphisa amandla okukhululwa kwe-mold. Yiloo ndlela insimbi engenasici kwifektri yezixhobo zamandla ihamba ukusuka kwinkcazo ukuya ekusebenzeni okuthembekileyo.
