Amabhawodi e-Monel aletha amandla angenakuqhathaniswa nokumelana nokugqwala lapho izibophelelo ezivamile zihluleka khona—amaphampu amanzi olwandle, amavalvu egesi emuncu, ama-multifold hydraulic hydraulic. Senze imishini engaphezu kuka-12,000 ye-Monel K-500 kanye ne-Monel 400 bolts ukuthola izindlu zephampu ezinomfutho ophezulu kusukela ngo-2019. Ngayinye yasinda ekuhlolweni kwesifutho sikasawoti ngaphezu kwamahora angu-3,000 ngaphandle kokubhoboza. Lokho akuwona ukusebenza kwethiyori. Lokho ukwethembeka okufakazelwe yinsimu ngaphansi kwemithwalo yangempela yama-cyclic, ukushaqeka okushisayo, nomoya ogcwele i-chloride.
Amabhawodi e-Monel awawona nje “insimbi engagqwali-plus.” Ziyingxubevange ye-nickel-copper—imvamisa i-nickel engu-67%, i-23% yethusi, kanye nezithako ezincane kodwa ezibalulekile ze-aluminium ne-titanium ku-K-500. Lokhu kwakheka kudala ama-microstructures aqiniswe kakhulu amelana nokuqhekeka kwe-stress-corrosion kangcono kunezinsimbi ezingama-316 ezingenasici noma eziyi-duplex. Embonini ye-valve ye-subsea yeklayenti elilodwa, ukushintsha ukusuka kumabhawodi e-Inconel 625 kuya ku-Monel K-500 kunciphise imvamisa yokushintshwa kwebholithi ngo-70% ezinyangeni eziyi-18. Kungani? Ngoba i-Monel igcina amandla esivuno angaphezu kuka-1,000 MPa kuyilapho imelana nokugqwala kwemifantu ku-pH 2–12 kanye nezinga lokushisa elifinyelela ku-480°C.
Kodwa amabhawodi akwaMonel afuna ukuhlonishwa—hhayi nje ukutuswa. Izinga labo lokuqinisa umsebenzi lidlulele. Ukuthepha okukodwa okungaqondani kahle ngesikhathi sokusika intambo kungaphula okungenalutho. Sibone amakhasimende elahlekelwa wonke amaqoqo ngoba asebenzise ompompi abajwayelekile be-HSS esikhundleni samathuluzi e-carbide anokulethwa okupholisayo okuqinile. I-Monel nayo ayikuphathi kahle ukushisa. Ngaphandle kokuphathwa okushisayo okunembayo ngesikhathi somshini, ukuhunyushwa kwendawo kuthambisa impande yentambo—kusike impilo yokukhathala phakathi. Kungakho sishisisa ngaphambili izikhala zibe ngu-120°C ngaphambi kokulutha, sebenzisa izigayo zokugcina ezipholile nge-cryogenic, futhi siqinisekise ubulukhuni kuzo zonke izindawo ezintathu zokukhanya kuzo zonke izindawo. Asikho isinqamuleli esisindayo kule alloy.
- Ukukhetha impahla kubaluleke ngaphezu kwenombolo yebanga. I-Monel 400 ifanela ukuchayeka kwamanzi olwandle amile; I-Monel K-500 ingeza ukuqina kweminyaka kokugcinwa kwetorque eguquguqukayo kumashafu epompo ajikelezayo.
- I-geometry yochungechunge ayikhethi-iyasebenza. Imicu ye-Unified National Fine (UNF) idlula izikhala ezimahhadlahhadla ezindaweni ezidlidliza kakhulu ngokusabalalisa i-clamp load ngokulinganayo.
- Ukuqedwa kwendawo kuthinta ngokuqondile ukuqala kokugqwala. I-Ra ≤ 0.4 μm ivimbela imifantu emincane lapho i-chloride igxila khona; i-electropolishing kunciphisa ukungasebenzi kahle kwesendlalelo ngo-92% uma kuqhathaniswa nokupholishwa kwemishini kuphela.
Abanye bangase baphikise ukuthi amabhawodi e-Monel abiza kakhulu—kufika ku-4× ngaphezu kwe-A2-70 engenasici. Nokho, izindleko eziphelele zobunikazi zixoxa indaba ehlukile. Omunye osebenza eNorth Sea ulandelele amajoyinti angama-hydraulic amaningi angama-14 ezinyangeni ezingama-24. Ngamabhawodi angenasici, benze ukuvalwa okungahleliwe okungahleliwe okungu-19 ukuze kushintshwe ibhawudi kanye nokuphinda kufakwe i-gasket. Ngamabhawodi e-Monel K-500, asebenze izinyanga ezingama-22 ngaphandle kokuvuza okukodwa kwelunga. Izindleko zomsebenzi, isikhathi sokuphumula, nokuqinisekisa ukuphepha zehle ngo-$217,000 ngonyaka. Ukumelana nokugqwala akusona isici. Kuhlehlisiwe ukugcinwa—kanye nengozi ehlehlisiwe.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imishini Amabhawodi e-Monel asebenzisa izikhungo ze-CNC eziqinisekisiwe ze-ISO 9001 ezinesinxephezelo sesikhathi sangempela sokushisa. Sithola amabhilidi aqinisekisiwe we-AMS 4675, siqinisekisa ukugeleza kokusanhlamvu ngaphambi kokufoja, futhi senza ukuhlola kwe-ultrasonic kuyo yonke inqwaba ukuze sithole ukufakwa ngaphansi komhlaba. Inqubo yethu ihlanganisa isixazululo se-annealing ku-980 ° C ± 5 ° C, ukucisha amanzi ngokushesha, bese ukuguga ku-650 ° C amahora angu-16-ngokuqondile nge-ASTM B564 ngayinye. Yonke ibhawudi ithwala ukulandeleka okugcwele: inombolo yokushisa, umbiko wokuhlolwa okuqinile, ukuhlolwa kokugqwala kwe-intergranular (ASTM G28A), kanye nedatha yobukhulu ye-CMM efakwe kungobo yomlando iminyaka engu-10. Uma udinga amabhawudi e-Monel abamba i-torque ngemva kwemijikelezo yengcindezi engu-50,000 ku-95°C brine—asiqageli. Siyakala, siyaqinisekisa, futhi siyaqinisekisa.
Uma ubheka phambili, amabhawodi e-Monel athuthuka ngale kokuqiniswa okumile. Manje sishumeka amageji ohlobo ku-Monel 400 bolt shanks ukuze kuqashwe ukulayisha kuqala kwesikhathi sangempela kuzisekelo zephampu ezibalulekile. Imiklamo yesizukulwane esilandelayo ihlanganisa iziteshi ezincane zokulethwa kwezithambisi ezisemgqeni ngesikhathi sokusebenza—ukunweba izikhawu zesevisi ezindaweni ezikude zikawoyela. Ikusasa aliphathelene namabhawodi e-Monel aqinile. Imayelana nezihlakaniphe kakhudlwana—eziklanywe ngenjongo, zaqinisekiswa ngedatha, futhi zakhiwe lapho ukwehluleka kungeyona inketho. Uma uhlelo lwakho lokusebenza ludinga ukuthi kungabi sengozini ebucayini, kukhemistri, noma ukungaguquguquki, amabhawodi emali akuzona ukukhetha kwakho okuhle. Bawukuphela kwesinqumo sakho.
