Graphite ozungulira

Graphite ozungulira ndi graphite impeller amapangidwa ndi kuyera kwambiri. Pamwambapa amathandizidwa ndi anti-oxidation yapadera, ndipo moyo wautumikiwu umakhala pafupifupi katatu kuposa mankhwala wamba. Ambiri ntchito makampani zotayidwa aloyi kuponyera.

Njira yodziyeretsa ya aloyi ya aluminiyamu ndiyo njira yayikulu yothetsera magwiridwe antchito onse a aloyi a aluminium. Pakutsuka, njira yosakanizira gasi loyeretsa ndi zosungunulira ndikupopera makina ozungulira a graphite kuti asungunuke zotayidwa ndiyo njira yotsogola kwambiri padziko lapansi. Mfundo yogwirira ntchito ya graphite rotor ndi iyi: ozungulira ozungulira amaswa nayitrogeni (kapena argon) yomwe imawombera mu aluminiyamu kusungunuka mumabala ambiri obalalika ndikuwabalalitsa muzitsulo zosungunuka. Mphukira zosungunuka zimadalira kusiyanasiyana kwamagesi ndi gawo lakumamatira kwapadziko lapansi kuti kuyamwa hydrogen mu kusungunuka, adsorb oxidized slag, ndikuchotsedwa pamalo osungunuka ngati thovu likukwera, kuti kusungunuka kuyeretsedwe. Chifukwa thovu ndi laling'ono komanso lobalalika, limasakanikirana mofanana ndi kusungunuka kwake, kenako limazungulira mozungulira kuti liziyandama pang'onopang'ono. Nthawi yolumikizirana ndi kusungunuka ndiyotalika, ndipo kutuluka kwa mpweya komwe kumachitika chifukwa chokwera mosalekeza sikupangidwe, potero kuchotsa hydrogen yoyipa mu kusungunuka kwa aluminium. Kulimbitsa kuyeretsa.

Pazitsulo zama aluminiyamu ndi mafakitale a aluminiyamu, ndikofunikira kuti muchepetse mtengo wogulira. Pankhaniyi, ma graphite rotors opangidwa ndi kampani yathu amatha kubweretsa zotsatirazi. 1. Kuchepetsa mtengo wogwiritsira ntchito 2. Kuchepetsa kugwiritsa ntchito mpweya wa inert 3. Kuchepetsa zotayidwa mu slag 4. Kuchepetsa ndalama zogwirira ntchito 5. Kupititsa patsogolo magwiridwe antchito, nthawi yayitali yosinthira 6. Sinthani kudalirika ndikuchepetsa ndalama zosamalira.

Chifukwa mafotokozedwe a makina a graphite omwe amagwiritsidwa ntchito pamtundu uliwonse wopanga kapena kuponyera sizofanana. Choyamba, kasitomala amapereka zojambula zoyambirira ndipo amadzaza mawonekedwe athunthu a graphite ozungulira. Kenako, malinga ndi zojambulazo, kuphatikiza liwiro la graphite ozungulira, mayendedwe a kasinthasintha ndi malo ake poyerekeza ndi mulingo wamadzimadzi a aluminiyamu, kuwunika kwaukadaulo kumachitika, ndipo kukaniratu kukana kukokoloka koyenera. Ndondomeko yothandizira okosijeni.

Graphite ozungulira nozzle unapangidwa mkulu-chiyero graphite. Kuphatikiza pa kulingalira zakufunika kotulutsa thovu, kapangidwe kake kamene kamagwiritsiranso ntchito mphamvu ya centrifugal yomwe imapangidwa ndikuyambitsa kusungunuka kwa aloyi ya aluminiyumu kuti isungunuke ilowe mumkombomo ndikusakanikirana mofananira ndi mpweya wotulutsidwa kuti ukhale mpweya / Jet yamadzi ndi sprayed kuonjezera malo kukhudzana ndi kukhudzana nthawi ya kuwira ndi zotayidwa aloyi madzi, ndi kusintha zotsatira degassing kuyeretsedwa.

Liwiro la ozungulira graphite akhoza steplessly kusintha ndi pafupipafupi Converter liwiro kulamulira, mpaka 700r / min. Mafotokozedwe a ozungulira graphite ndi Φ70mm ～ 250mm, ndi mfundo za impeller ndi Φ85mm, 350mm. Mpweya wa graphite wa anti-oxidation wotsika kwambiri uli ndi mawonekedwe a mphamvu yayikulu, kutentha kwambiri, komanso zotayidwa zotulutsa dzimbiri. Pokonza ndi kuyeretsa, pamwamba pamadzi a aluminiyamu omwe ali m'bokosimo ali ndi nayitrogeni kuti atetezedwe, kotero kuti gawo la graphite rotor lomwe limatulutsidwa kuchokera ku zotayidwa ndi aloyi madzi ali mu mpweya wambiri kuti ateteze kutentha kwambiri ozungulira ndi kutalikitsa moyo wautumiki wa ozungulira.

Mawonekedwe amtunduwo amayendetsedwa bwino, zomwe zimatha kuchepetsa kulimbikira panthawi yosinthasintha, ndipo mkangano ndi kukwapula pakati pa impeller ndi madzi a aluminium alloy ndi ochepa. Kotero kuti mlingo wa degassing uli pamwamba pa 50%, kufupikitsa nthawi yosungunuka ndikuchepetsa mtengo wopangira.
