graphite rotor

1. Thegraphite rotorinoshanda nguva dzose mualuminium yakanyunguduka inenge 750 ° C pakukurumidza kwe 200r / min ~ 400r / min, uye hupenyu hwese hwebasa hunodiwa kuti husvike kupfuura mwedzi mumwe.Thegraphite rotoryekambani yedu yakagadzirwa nepamusoro-kuchena graphite.Unhu hwegraphite pachahwo hune simba rakakosha pahupenyu hwebasa re rotor.Panguva imwecheteyo, anti-oxidation inodzivirira yekudzivirira inoshandiswa pamusoro, uye hupenyu hwebasa hunogona kuwedzerwa kusvika mazuva 50-60.

2. Kushanda musimboti wegraphite rotor:

Iyo graphite rotor inoumbwa ne rotor tsvimbo uye nozzle.Nzira yekufambisa inofambisa graphite rotor kutenderera, uye argon kana nitrogen inoputirwa mualuminium inonyunguduka kuburikidza ne rotor rod uye nozzle.Iyo yepamusoro-speed inotenderera graphite rotor inopwanya argon kana nitrogen gasi inopinda muaruminiyamu inonyunguduka kuti iumbe mabhuru madiki akawanda, anoaparadzira musimbi yakanyungudutswa.Kana mabubbles arikusangana, mabhuru ari mukunyunguduka anovimba negasi partial pressure mutsauko uye musimboti wekunyungudika kwepasi kuti utore hydrogen mukunyunguduka, adsorb oxidized slag, uye abudiswe kunze kwenzvimbo yakanyunguduka sezvo mabhuru anosimuka kuti achenese. the melt.

Kushandisa uye kugadzirisa graphite rotor:

1. Iyo inotenderera inotenderera inogadzirwa nepamusoro-kuchena graphite.Pamusoro pekutarisa maumbirwo emhumhu yekupwanya mabhuru emhepo, inoshandisawo simba recentrifugal rinogadzirwa nekukuchidzira aruminiyamu alloy kunyunguduka kuita kuti inonyungudika ipinde mumhuno uye isanganise negasi rakadzimwa rakachinjika kuita gasi.or kuyerera kwemvura kunobviswa kuti iwedzere nzvimbo yekubatana uye nguva yekubata pakati pemabhubhu nealuminium alloy fluid, uye kunatsiridza degassing uye kuchenesa maitiro.

2. Chinodiwa chehupenyu hwesevhisi chinodarika mwedzi mumwe.Iyo yakasimba ndeye 3-4 nguva iri nani pane iyo isiri-oxidizing rotor.Inogona kugara mazuva anosvika 55-65 pa700 ° C, uye inogona kugara kusvika kumazuva 25-35 pane tembiricha iri pamusoro pe1000 ° C.Iine anti-oxidation inodzivirira coating pamusoro, hupenyu hwesevhisi hunogona kuwedzerwa kusvika ku50-60 mazuva.

3.Usati wanyudza graphite rotor mumvura yealuminium, preheat iyo kwemaminitsi mashanu kusvika kumaminitsi gumi pane inenge 100 mm pamusoro pemvura yemvura kuti udzivise kukanganisa kwekukurumidza kutonhora pane zvinhu;iyo rotor isati yanyudzwa mumvura, gasi rinofanira kupfuudzwa; Mhepo yemhepo inogona kumiswa chete mushure mokunge rotor yasimudza kubva pamvura, kuitira kudzivirira gomba remhepo ye rotor nozzle kubva pakuvharwa.

4. Chikonzero chikuru che graphite rotor kukuvara ndeyekupisa-kupisa oxidation: chikamu chikuru che graphite kabhoni, uye graphite inogona kuoneka oxidized pasi pemamiriro emhepo anopfuura 600 ° C. Zvigadzirwa zve carbon oxidation reactions ndeye CO uye CO2 magasi, ayo haigoni kudzivirira rotor.Kazhinji kutaura, bhokisi re degassing harigoni kuvharwa zvachose, uye yakawanda yemukati yebhokisi yebhokisi haina kuzadzwa nekudzivirira gasi, saka oxidation ye graphite rotor haidzivisiki.Nekuda kweiyo oxidation, iyo shaft dhayamita ye rotor shaft inoderera zvishoma nezvishoma kusvika yatsemuka uye yaraswa.
