Graphite ncej thiab rotors rau koj cov kev xav tau kev lag luam

Graphite ncej thiab rotors rau koj cov kev lag luam xav tau?

Graphite rotors thiab Shaftsyog nquag siv raws li cov tseem ceeb ntawm ntau cov kev lag luam. Txawm hais tias qhov tsis tseem ceeb, lawv ua lub luag haujlwm tseem ceeb hauv kev tsim cov txheej txheem xws li txhuas, thiab ua haujlwm tseem ceeb ntawm kev ua kom zoo thiab ua haujlwm ntawm kev lag luam niaj hnub.

Txhuas Raug: Ib qho ntsiab lus txuas rau kev txhim kho zoo dua

Nyob rau hauv txhuas ua, graphite rotors thiab sharats daim ntawv rau cov tub ntxhais ntawm molten disulation system. Lawv yog kev sib hloov cov khoom nruab nrab nruab rau qhov kawg ntawm chav tsev kho kom huv. After high-purity nitrogen or argon gas is introduced, the graphite rotor rotates at high speed (typically 400-600 rpm), breaking the gas into micron-sized bubbles and dispersing them evenly in the molten aluminum. Cov npuas npuas ua zoo li suav me me "Adsorption Carrien," Zoo siab ntes hydrogen thiab oxide suav nrog lawv sawv, thaum kawg nqa impurities rau saum npoo. Cov txheej txheem no ncaj qha txiav txim siab ntom thiab cov khoom siv tshuab ntawm lub zog tau txo qis dua 70%, muab cov khoom siv tensoses ntau dua li 30%, muab cov khoom siv kom zoo dua li 30%, muab cov khoom siv kom zoo xws li aerospace thiab kho tsheb.

Kev Tsim Tshuaj Khoom: Txhim khu kev qha txhim kho corrosion

Hauv kev lag luam tshuaj,Graphite rotors thiab ShaftsUa rau pom cov txiaj ntsig zoo hauv kev tuav cov xov xwm corrosive. Lawv ua haujlwm ua cov khoom sib kis hauv ntau cov twj pob mais, cov neeg tsis siab, thiab cov khoom siv sib xyaw. Ntsib nrog kev txhim kho ib puag ncig xws li hydrochloric acid thiab sulfuric acid thiab cov khoom siv hlau tsoos hlau sai sai, ua rau nws xaiv zoo tshaj plaws. Cov rotors uas tsis tu ncua nyob rau hauv cov kua dej corrosive, kom muaj kev sib xyaw ua ke ntawm reactants thaum saib xyuas cov kua dej ruaj khov. Cov ntaub ntawv kev tshawb fawb los ntawm cov nroj tsuag tshuaj tau qhia tias nyob rau hauv 30% hydrochloric acid cleid, kev pabcuam lub neej yog ntau tshaj 20 zaug uas txo cov nqi kho thiab cov nqi ntau lawm.

Cov Machinery: Kev ua haujlwm ruaj khov hauv qhov siab -} qhov chaw ib puag ncig

Nyob rau hauv high -} sov ua haujlwm thiab txuas ntxiv casting crystallizers, graphite rotors thiab Shafts kuj ua tau zoo zoo. Lawv ua haujlwm tseem ceeb xws li high - kub bearings thiab ringsing. Thaum lub teb chaws kub tshaj lub boiling point ntawm cov roj lubricating roj, graphite tus kheej lubricating cov khoom siv tsis muaj lubrication. Hauv cov kab ntau lawm, graphite bearings muaj qhov kub tsis tu ncua txog 800 degree, tswj kev sib txhuam coefficient hauv qab no 0.15, ua kom tiav kev sib txhuam thiab kev ruaj ntseg ntawm cov txheej txheem ntau lawm. Cov xeeb ceem no ua rau graphite Cheebtsam xaiv ib qho kev xaiv IT6 9}}}} pa kev lag luam rau kev tsim khoom tshwj xeeb.

Nrog kev txhim kho cov khoom lag luam tshiab ntawm cov ntaub ntawv tshiab, lub thaj tsam ntawm cov duab graphite graphite cov ntsiab thiab cov ntaub ntawv yog nthuav tas li. Los ntawm kev txhim kho cov ntaub ntawv zoo los daws cov kev ua haujlwm hnyav, "nrog lawv cov khoom siv niaj hnub ua rau muaj kev lag luam niaj hnub,
