Graphite Rotor

Iyo graphite rotor uye graphite impeller inogadzirwa neiyo yakachena-yakachena graphite. Iyo yepamusoro inobatwa neakasarudzika anti-oxidation, uye hupenyu hwebasa hunenge katatu nguva yezvakajairwa zvigadzirwa. Vakawanda kushandiswa aruminiyamu chiwanikwa Kudzingwa indasitiri.

Iyo yekuchenesa maitiro emvura aruminiyamu chiwanikwa ndiyo nzira huru yekuvandudza kuita kwese kuita kwealuminium alloy. Mukuita kwekuchenesa, nzira yekusanganisa gasi rekuchenesa uye solvent uye kumwaya graphite rotor kune iyo aluminium melt yekunatsa ndiyo yepamusoro nzira yekurapa pasi rose. Anoshanda musimboti we graphite rotor ndeiyi: iyo inotenderera rotor inopwanya iyo nitrogen (kana argon) inoputirwa mualuminium yakanyungudika kuita nhamba huru yemabhuru akapararira uye anovaparadzira musimbi yakanyungudutswa. Mabhonzo ari mukunyungudika anovimba nemweya wakasarudzika kumanikidza kusiyanisa uye musimboti wepasorosorosheni yekumwa hydrogen mukunyungudika, adsorb yakasungwa slag, uye kuburitswa munzvimbo inonyungudika sezvo mabvu achisimuka, kuitira kuti iyo nyungudika inogona kucheneswa. Nekuti mabhuru acho madiki uye akapararira, akasangana zvakaenzana nekunyungudika, uyezve iwo anotenderera muchimiro chakatenderera kuti ayangarara zvishoma nezvishoma. Iyo yekuonana nguva pamwe nekunyungudika yakareba, uye kuyerera kwemhepo kunogadzirwa nekuenderera kunowirirana kumuka hakuzoumbike, nokudaro kubvisa iyo inokuvadza hydrogen mualuminium melt. Yakagadziridzwa yekuchenesa mhedzisiro.

Kune aluminium alloy foundries uye aluminium chigadzirwa mafekitori, zvakakosha kuti udzikise mari yekugadzirisa. Panyaya iyi, graphite rotors inogadzirwa nekambani yedu inogona kuunza zvinotevera mabhenefiti. 1. Deredza mutengo wekugadzirisa 2. Deredza kudyiwa kwegesi inert. 3. Deredza zvigadzirwa zvealuminium mune slag 4. Deredza mutengo wevashandi. 5. Kuvandudza mashandiro, kuwedzeredza kutenderera 6. Kuvandudza kuvimbika uye kudzikisa mari yekuchengetedza.

Nekuti iwo maratidziro e graphite rotors anoshandiswa mune yega yega kukanda kana kukanda-rolling yekugadzira tambo haina kufanana. Kutanga, mutengi anopa ekutanga dhizaini dhizaini uye anozadza mune yakazara graphite rotor munda shandisa zvakatipoteredza ongororo fomu. Zvino, maererano nemadhirowa, akasanganiswa neiyo graphite rotor kumhanya, kutungamira kwekutenderera uye chinzvimbo chayo kune iyo aruminiyamu mvura nhanho, kuongororwa kwehunyanzvi kunoitwa, uye kwakakodzera kupokana nekukurwa kwevhu kunokurudzirwa. Oxidation kurapwa chirongwa.

Iyo graphite rotor inotenderera kamwene inogadzirwa neiyo yakachena-yakachena graphite. Kunze kwekutarisa kudiwa kwekutyora mabhuru, chimiro chekomboni chinoshandisawo simba re centrifugal rinogadzirwa nekusimudzira iyo aluminium alloy melt kuita kuti iyo melt ipinde mumuromo uye yakaenzana inosangana negasi rakadzururwa gasi kuti riite gasi / Iyo mvura jeti inosaswa kuti iwedzere nzvimbo yekutaurirana uye nguva yekubata yeiyo bubble uye yealuminium alloy mvura, uye nekuvandudza iyo degassing yekuchenesa mhedzisiro.

Iko kumhanya kweiyo graphite rotor inogona kusapindurwa neyakajairwa shanduko yekumhanyisa kutonga, inosvika ku700r / min. Tsanangudzo ye graphite rotor ndeye -70mm ～ 250mm, uye iyo mamiriro eempeller ndeye -85mm, 350mm. Iyo yakachena-yakachena anti-oxidation graphite rotor ine hunhu hweakakwira simba, yakanyanya kupisa tembiricha, uye aruminiyamu kuyerera ngura kuramba. Mukuita kwekuchenesa uye kushatisa, pamusoro pealuminium chiwanikwa chemvura mubhokisi rakafukidzwa ne nitrogen yekudzivirira, kuitira kuti chikamu che graphite rotor iratidzwe kubva kune aruminiyamu chiwanikwa mvura iri mune inert gasi kudzivirira yakanyanya tembiricha oxidation ye iyo rotor uye kuwedzera hupenyu hwebasa reiyo rotor.

Maumbirwo emhepo inoyerera, izvo zvinogona kudzikisira kushorwa panguva yekutenderera, uye kukakavara uye kurwisa simba pakati pemupepereta nealuminium alloy fluid ishoma. Zvekuti chiyero che degassing chiri pamusoro pe50%, kupfupisa iyo yekunyungudutsa nguva uye kudzikisa mutengo wekugadzira.
