Yini ipayipi lensimbi elingagqwali?

Ukubukwa: 0 Umbhali: Isikhathi Sokushicilela Isihleli Sokushicilela: 2022-03-15 Imvelaphi: Isizango

Ibanga Lokuhlanza (Ibanga lokudla) Amapayipi ensimbi angenasici asetshenziswa kabanzi emikhakheni eminingi kanye nezimboni ezinjengezemithi, ividiyo, ubhiya, ukuphuza amanzi, ubunjiniyela bezempi, imboni yokuhlanza umoya kanye nokunye ukwakhiwa komoya kanye nokwakhiwa kolunye uhlobo lwezomnotho lukazwelonke. Kunokuningi okungeniswa konyaka njalo ngonyaka.

1. Ukuhlaziywa komhlaba kwensimbi engenasici

Kokubili indlela ye-AES kanye nendlela ye-SPS kungasetshenziselwa ukuhlaziya indawo yensimbi engenasici ukuthola ikhono lokugqwala kwezindawo ezingaphakathi zensimbi engaphakathi. Ububanzi bokuhlaziya obukhishwe yi-AES buncane kakhulu, obungaba ngaphansi kwe-20nm. Umsebenzi wayo wokuqala ukukhomba izakhi. Inani lokuhlaziya le-XPS Litay lingaba ngu-10μM, elisetshenziselwa ikakhulukazi ukuthola isimo samakhemikhali sezinto eziseduzane.

Ukuskena ngaphezulu kwensimbi ebunjiwe yensimbi engama-316 engagqwali evezwe emkhathini nge-AES kanye ne-XPS Storictors ikhombisa ukuthi ukujula okujwayelekile kokuhlaziywa kwe-iromid diamond suple is 15nm, futhi ihlinzeka ngemininingwane mayelana nokwakhiwa nobukhulu besendlalelo sokuhamba. Ukumelana nokugqwala nokunye.

Ngokusho kwencazelo, insimbi engenasici ane-autenitic iqukethe i-chromium ephezulu ne-nickel, kanti ezinye ziqukethe i-molybdenum, titanium, njll., Ngokuvamile ziqukethe i-10.5% noma ngaphezulu Ukumelana nokugqwala kungumphumela wezakhiwo ezivikelayo zesendlalelo se-chromium-rich. Isendlalelo sokuhamba ngokuvamile singu-3-5nm sikhulu, noma silingana nama-athomu ayi-15 ubukhulu. Isendlalelo sokuhamba sakhiwa ngesikhathi senqubo yokusabela ye-oxidation-redration lapho i-chromium ne-iron isebenza khona. Uma ungqimba lokuhamba lilimele, kuzokwakheka ungqimba olusha lokudlula ngokushesha futhi ukugcwala kwe-electrochemical kuzovela ngokushesha, futhi kuzovela amabala ajulile wensimbi engagqwali. Ukugqwala kanye nokugqwala kokuhlangana. Ukuvikelwa kokugqwayiza kokuphamba kuhlobene nokuqukethwe kwezakhi zamakhemikhali eziqukethwe ngensimbi engenasici, njenge-chromium ephezulu, i-nickel kanye ne-molybdenum, njll. Kungakhuphula amandla okubopha amandla wesendlalelo sokuhamba, futhi athuthukise ukuqina kongqimba; futhi uyisebenzise ngenhla engaphakathi yepayipi lensimbi engenasici. I-fluid medium ihlobene.

2. Ukugqwala komhlaba kwepayipi lensimbi engenasici

. Uma ungqimba lokuhamba luse-Metal kuphela, ungqimba oluphrintiwe luzoqhubeka nokulungisa. Ezimweni eziningi, isendlalelo sokuhamba salimala kuphela endaweni yendawo yensimbi. Umphumela wokugqwala ukwakha izimbobo ezincane noma imigodi. Imigodi emincane esatshalaliswa ngezikhathi ezithile ebusweni bezinto ezibonakalayo ibizwa ngokuthi i-cormonition ekhonyisayo. Izinga lokugqwala lokuphamba likhuphuka ngokushisa okwandayo nokwenyuka kokuhlushwa okwandayo. Isixazululo ukusebenzisa i-Ultra-Low noma i-Carbon Sterainless yensimbi (njenge-316l noma 304L)

. Lapho izinga lokushisa lokushisa kanye nesivinini sokushisa ngesikhathi sokukhiqiza kanye ne-welding zisesifundeni sensimbi esingenasici (cishe nge-425-815 ° C) Ngenxa yalokhu, okuqukethwe kwe-chromium komngcele wokusanhlamvu kuyancipha ngokuqhubekayo ngemvula eqhubekayo ye-chromium carbide, yakha indawo ebizwa ngokuthi yi-chromium-depleted zone, yehlisa amandla akhona futhi kunciphisa ukumelana nokwehlukana kwesendlalelo se-pasivation. Uma uhlangana nemidiya eqinile efana ne-CI- in the medium, kuzodala ukugqwala kwamanje kwamanje. Yize ukugqugquzelwa kusebusweni bezinhlamvu, kungena ngaphakathi ngaphakathi ukuze kwakhiwe ukugqwala okuqhubekayo. Ikakhulu ipayipi lensimbi elingagqwali lisobala kakhulu engxenyeni yokwelashwa kwe-welding.

(3) Ukuqhekeka kokugqwala kwengcindezelo Imvelo yokuqhekeka kokugqwayiza kokuphazamiseka imvamisa iyinkimbinkimbi impela. Hhayi ukucindezela okuthe xaxa kuphela, kepha inhlanganisela yale ngcindezi kanye nengcindezi eyinsalela kwinsimbi ngenxa yokwakhiwa, ukuthukuthela, noma ukwelashwa okushisa.

3. Inqubo yokukhiqiza yepayipi lensimbi elingagqwali

Ekhipha i-ungcoling-welding-welding-welding (ibhokisi lokuvikela igesi) -Imigomo yokugaya umthungo-welding yokuhlanza umfutho - ukuhlanza okukhanyayo okukhanyayo - ukunciphisa okukhanyayo

Kunconywa ukusebenzisa ukunemba kwensimbi engenasici i-Stainler fluid Umugqa Wokukhiqiza Amapayipi Hangao tech (seko mishini) . Njengoba umucu wensimbi usetshenziselwa ukufudumala ngokuqondile ngemuva kokwakha, ukubekezelelana kanye ne-ellipticity yepayipi kungalawulwa kahle, futhi inqubo yokudweba ebandayo ingashiywa.

Kunemishini eminingana ebalulekile ekukhiqizeni:

(1) Imishini Yezinga Langaphakathi : Ingacindezelwa kaninginingi emuva nakwi-roller kanye ne-mandrel eyakhelwe ngaphakathi ukuze unciphise ubude obusele bomthungo we-welding, ukuze umthungo we-welding kanye nodonga lwesisekelo, ukwehlisa izinsalela zepayipi ngaphakathi. Ngesikhathi sokupholisha kwangaphakathi nokuphoqelela kwangaphandle, kunganciphisa futhi inani namandla okupholisa nokunciphisa ukulahleka.

Umzimba Wokukhanyisa Okhanyayo: Isakhiwo Esiyinhloko Siyisigaba Esiyindilinga Ukufakwa kwe-inducting futing , okuthatha indlela yokushisa yokufudumeza yokufudumeza amakhoyili, ukuze lonke isigaba sepayipi lifuthelwe kuzo zonke izinkomba. Igesi evikelayo ayisebenzi nje kuphela njengesithiyo emoyeni, kodwa futhi isebenza njengomoya opholile ojikelezayo. Isakhiwo esihlangene, ukusebenza okuphephile, ukulawulwa okuthembekile nokulungiswa okulula. Umehluko wokushisa esithandweni somlilo ulawulwa ngaphakathi ± 1-2 ℃.

Abakhiqizi bangakhetha ukusebenzisa imishini yokubola kwe-ammonia ukwenza igesi evikelayo noma basebenzise ngqo igesi ekheniwe ngokuya ngezimo zabo zangempela.
