Iinxalenye ze-Monel ze-400 zihambisa ukuchasana okungenakuthelekiswa namanzi olwandle, i-acids, kunye ne-alkalis-ezenza zibe yimfuneko apho ukusilela kungenakuzikhethela. EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siye ngoomatshini phezu 12,000 Monel 400 iinxalenye zevalve hydraulic, izindlu zempompo subsea, kunye offshore winch shafts ukususela 2018. Uninzi iinjineli abayiqondi: ukukhetha ekunene Monel 400 inxalenye kwihingesi eyongezelelekileyo kwi chemistry ngaphantsi kwe chemistry ngaphantsi kwe hinge Uxinzelelo olwenziwa ngoomatshini, kunye nokugqiba komphezulu kunxibelelana kwindawo yakho yenkonzo ethile.
Kutheni iMonel 400 Isilela—Naxa “Ichazwe Ngokuchanekileyo”
Siye sabona izizathu ezintathu eziphindaphindiweyo ezibangelwa ukusilela kwintsimi ye-47 ebandakanya iinxalenye ze-Monel ze-400. Okokuqala: ukusebenzisa isitokhwe sebha ye-ASTM B164 kwizindlu ze-cylinder ezinoxinzelelo oluphezulu ngaphandle kokuqinisekisa isikhokelo sokuhamba okuziinkozo-okukhokelela ekudinweni kwangaphambi kwexesha ukuqhekeka ecaleni kweendawo ezinqamlezileyo ze-weld. Okwesibini: ukusebenzisa imilinganiselo yokusika i-stainless steel stainless ngexesha lokujika kwe-CNC, okubangela ukuba umsebenzi ube lukhuni obamba uxinzelelo olushiyekileyo kwaye lubangele uxinzelelo lwe-corrosion cracking kwi-condensate ene-chloride ecebileyo. Okwesithathu: ukutsiba i-post-machining acid pickling ngaphambi kokugqithisa, ukushiya amasuntswana entsimbi afakelweyo aqala i-galvanic pitting.
I-Monel 400 ye-67% ye-nickel-30% isiseko sobhedu inika ukukhuseleka ekunciphiseni i-acids efana ne-hydrofluoric-kodwa ayinikezeli ukhuseleko kwi-oxidizing agents njenge-ferric chloride okanye igesi ye-chlorine emanzi. Ukuba isicelo sakho siquka imijikelo yokomisa kwamaxesha okanye ibhayisekile eshushu ngaphezu kwe-400°C, qwalasela iMonel K-500 endaweni yoko. Sivavanya yonke i-Monel 400 billet nge-spark emission spectroscopy-kungekhona nje umlinganiselo we-Ni / Cu, kodwa umxholo wesulfure ongaphantsi kwe-0.002%, ochaphazela ngokuthe ngqo ukukrazula okutshisayo ngexesha lokutshala imali.
Indlela yokuTshatisa iCandelo leMonel 400 kumthwalo wakho wehlabathi lokwenyani
Qala ngokwenza imephu imvulophu yakho yokusebenza-hayi nje uxinzelelo kunye nobushushu, kodwa isantya solwelo, ukulayisha amasuntswana, kunye nokuvalwa rhoqo. Umzekelo:
- Izindlu zempompo ze-cylinder: Funa i-centrifugally cast Monel 400 ene-radial grain structure-eyenziwe ngokusebenzisa i-RPM ephantsi, i-high-feed passs ukuze igcine i-compressive surface residual stress.
- Izihlalo zevalvu yamanzi olwandle: Imfuno eyenziwe ngeMonel 400 (ASTM B564) kunye nobunzima phakathi kwe-130-160 HB; ifakwe emva kokusila kokugqibela ukuphelisa i-microcracks kwi-EDM recast layers.
- Offshore winch centre shaft rollers: Kufuneka ibe isisombululo-i-annealed kwi-1177 ° C ± 14 ° C, emva koko ucinywe ngamanzi-awuzange upholise umoya-ukuthintela ukutshatyalaliswa kwesigaba se-sigma kwindawo echaphazelekayo ukushisa.
Siyayigatya i-8.3% ye-Monel 400 ye-raw material batches ngenxa yokungahambelani kwe-intergranular corrosion resistance-eqinisekiswe yi-ASTM G28 Indlela yokuvavanya. Olo qeqesho lwahlula amacandelo abalulekileyo kubuthunywa kubunzima bamaphepha abizayo.
Iindleko ezifihlakeleyo zeMonel 400 "Standard" Fabrication
Abathengi abaninzi bacinga ukuba i-Monel 400 iinxalenye zibiza i-3 × insimbi engenasici-kwaye umise apho. Kodwa ixabiso lilonke lobunini lixhomekeke kwizinto ezintlanu ozilawulayo: ukupakisha ukunyamezelwa kwemilinganiselo, uburhabaxa bomphezulu, indlela yokuqinisekisa unyango lobushushu, ubunzulu beprothokholi yohlolo, kunye nomda wokulandeleka. Intonga ye-Monel 400 ye-piston ene-± 0.01 mm yokunyamezela kunye ne-Ra 0.4 μm yokugqiba ixabisa i-22% ngaphezu kweyodwa kunye ne-± 0.05 mm kunye ne-Ra 1.6 μm-kodwa iphelisa i-94% yezikhalazo zokuvuza kwetywina kwiinkqubo eziphezulu zomjikelo we-hydraulic.
Sisebenzisa i-Zeiss CONTURA G2 CMMs kunye neeprobes ze-ruby ezilinganisiweyo zokuqinisekisa i-diameter ebalulekileyo phantsi kwe-20 ° C elawulwayo kwiimeko eziphantsi-kungekhona ukushisa kwegumbi. Ngoba? I-coefficient ye-Monel 400 yokwandiswa kwe-thermal yi-13.7 μm/m · ° C. I-swing ye-10 ° C yazisa impazamo ye-0.137 mm kwi-shaft ye-1,000 mm. Yiyo loo nto i-Monel 400 yethu iyinxalenye yezatifikethi ibandakanya iilogi zokusingqongileyo ecaleni kweengxelo ezinobungakanani.
Yintoni eza emva kokuKhethwa-kwaye kutheni ibalulekile ngaphezu kokuba ucinga
Ukukhetha i-Monel 400 ekunene inxalenye iphela xa iprototype yakho yokuqala ifika. Okulandelayo kuya kugqiba ukuba iyaqhuba okanye iyasilela ngokuthula. Senza amanyathelo amathathu angenakuxoxisana kuwo wonke umyalelo: (1) uvavanyo lwe-ultrasonic nge-ASTM E114 ye-porosity yangaphakathi kwi-cast housings, (2) uvavanyo lwe-ferroxyl nge-ASTM A380 ukuqinisekisa ukungabikho kokungcoliswa kwentsimbi yamahhala, kunye (3) nokuqinisekiswa kwe-salt-spray nge-ISO 9227 kwiiyure ze-1,000-ngaphandle kokuchukumisa okanye ukuphinda usebenze.
Abathengi bethu kwiiprojekthi ze-oyile yoLwandle lwaseMantla kunye negesi zifuna ukulandelelwa ngokupheleleyo kwebhetshi ukuya kuthi ga kwi-Inconel 600 master alloy lot esetyenziselwa ukunyibilikisa. Sigcina iirekhodi zedijithali ezidibanisa inxalenye nganye ye-Monel 400 kwinani layo lobushushu, i-ID yokufaka i-ID, i-log yesixhobo se-CNC, kunye nesitampu sokugqibela sokuhlola. Akukho ngaphandle.
Ukusebenza kwenxalenye ye-Monel 400 ayiqinisekiswanga ngokucaciswa-ifunyenwe ngoqeqesho lwe-metallurgical, ulawulo lwenkqubo, kunye nokuqinisekiswa kwehlabathi langempela. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha icandelo ngalinye le-Monel 400 ngokungathi liya kusebenza lingajongwanga kubunzulu be-3,000 yeemitha. Kuba ngokufuthi, kuyenzeka.
