Imashini ya Monel itanga imbaraga ntagereranywa hamwe no kurwanya ruswa aho ibifunga bisanzwe byananiranye - pompe zamazi yo mu nyanja, imyuka ya gaze ya gaz, amashanyarazi ya hydraulic yo hanze. Twakoze imashini zirenga 12,000 Monel K-500 na Monel 400 zo kubamo amazu ya pompe yumuvuduko mwinshi kuva muri 2019. Buriwese yarokotse igeragezwa ry-umunyu kurenza amasaha 3.000 atarinze. Ntabwo aribikorwa bya theoretical. Nibyo byerekanwe-kwizerwa munsi yumuzigo nyawo wa sikeli, ihungabana ryumuriro, hamwe nikirere cyuzuye chloride.
Monel bolts ntabwo ari "ibyuma-byongeweho." Ni nikel-umuringa wavanze-mubisanzwe 67% nikel, 23% y'umuringa, wongeyeho utuntu duto ariko twinshi twa aluminium na titanium muri K-500. Iyi miterere ikora microstructures irwanya imvura igoye irwanya guhangayika-kwangirika kurenza 316 ibyuma cyangwa ibyuma bya duplex. Mumukiriya umwe wo muri offshore valve inteko, guhinduranya kuva muri Inconel 625 kuri Monel K-500 yagabanije inshuro zisimbuza bolt 70% mumezi 18. Kubera iki? Kuberako Monel ikomeza gutanga umusaruro hejuru ya MPa 1.000 mugihe irwanya ruswa ya pH 2–12 nubushyuhe bugera kuri 480 ° C.
Ariko Monel bolts isaba kubahwa - ntabwo ari ugushimwa gusa. Igipimo cyabo cyo kunaniza akazi kirakabije. Kanda imwe idahuye mugihe cyo gukata urudodo irashobora kuvunika ubusa. Twabonye abakiriya batakaza ibyiciro byose kuko bakoresheje kanseri isanzwe ya HSS aho gukoresha ibikoresho bya karbide hamwe no gutanga ibicuruzwa bikonje. Monel nayo ikora ubushyuhe nabi. Hatabayeho gucunga neza ubushyuhe mugihe cyo gutunganya, annealing yaho yoroshya imizi yumutwe - kugabanya ubuzima bwumunaniro mo kabiri. Niyo mpamvu dushyushya ubusa kugeza kuri 120 ° C mbere yo gutondeka, gukoresha urusyo rukonjesha rukonjesha, kandi tugenzura ubukana muri zone eshatu za radiyo kuri buri kintu. Nta shortcut irokoka iyi mavuta.
- Guhitamo ibikoresho bifite akamaro kuruta umubare wamanota. Monel 400 ikwiranye n'amazi yo mu nyanja ahamye; Monel K-500 yongeramo imyaka-gukomera kugirango imbaraga za torque zigumane mumashanyarazi azunguruka.
- Imitwe ya geometrie ntabwo ihitamo-irakora. Ihuriro ryigihugu ryiza (UNF) riruta ibibanza bito cyane mubidukikije bihindagurika cyane mugukwirakwiza clamp imitwaro iringaniye.
- Kurangiza isura bigira ingaruka itaziguye. Ra ≤ 0.4 μm irinda micro-crevices aho chloride yibanda; amashanyarazi agabanya inenge ya passi-layer kuri 92% na mashini ya mashini yonyine.
Bamwe bashobora kuvuga ko Monel bolts igura amafaranga menshi - kugeza kuri 4 × kurenza A2-70 idafite ingese. Ariko, igiciro cyose cya nyirubwite kivuga inkuru itandukanye. Umukozi umwe wo mu nyanja y'Amajyaruguru yakurikiranye 14 hydraulic manifold ihuza amezi 24. Hamwe na bolts idafite umwanda, bakoze 19 bahagaritse gahunda yo guhagarika gusimbuza bolt na gasketi. Hamwe na Monel K-500, yakoresheje amezi 22 nta kantu kamwe kamwe. Amafaranga yo gukora, amasaha yo hasi, hamwe no kugenzura umutekano yagabanutseho $ 217,000 buri mwaka. Kurwanya ruswa ntabwo ari ibintu biranga. Ni ugukererwa kubungabunga-hamwe ningaruka zidindiza.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imashini Monel ikoresheje ISO 9001 yemewe na CNC ibigo hamwe nindishyi zigihe-nyacyo. Dutanga AMS 4675 yemewe na fagitire, kugenzura imigendekere yintete mbere yo guhimba, no gukora ultrasonic igenzura kuri buri cyiciro kugirango tumenye ibibera munsi yubutaka. Inzira yacu ikubiyemo igisubizo kuri 980 ° C ± 5 ° C, kuzimya amazi byihuse, hanyuma gusaza kuri 650 ° C mumasaha 16 - cyane kuri ASTM B564. Buri bolt itwara ibisobanuro byuzuye: umubare wubushyuhe, raporo yikizamini cya tensile, ikizamini cyangirika hagati (ASTM G28A), hamwe namakuru ya CMM yibitse mumyaka 10. Mugihe ukeneye Monel bolts ifata torque nyuma yikigereranyo cya 50.000 cyumuvuduko muri 95 ° C brine-ntidukeka. Dupima, twemeza, kandi twishingira.
Urebye imbere, Monel ihindagurika irenze kwihagararaho. Ubu turimo gushyiramo ibipimo byerekana imiterere ya Monel 400 ya bolt shanks yo kugenzura igihe nyacyo cyo kugenzura mbere na mbere pompe zikomeye. Ibisekuruza bizakurikiraho bihuza imiyoboro mito yo gutanga amavuta mugihe cyo gukora-kwagura intera mugihe cya peteroli ya kure. Igihe kizaza ntabwo kijyanye na Monel ikomeye. Byerekeranye nubwenge-bwateguwe bufite intego, bwemejwe namakuru, kandi bwubatswe aho gutsindwa atari amahitamo. Niba porogaramu yawe isaba gutandukana zeru kubunyangamugayo, chimie, cyangwa guhuzagurika, monel bolts ntabwo ari amahitamo yawe meza. Ni amahitamo yawe yonyine.
