Hauv cov khoom siv ua ntawv, cov lus qhia ntawm "Yankee dryers" tsis tshua piav qhia hauv "kilograms". Hloov chaw, cov kev ntsuas xws li txoj kab uas hla (piv txwv li, 1.5m, 2.5m), ntev, ua haujlwm siab, thiab tuab ntawm cov khoom siv yog qhov ntau dua. Yog tias "3kg" thiab "5kg" ntawm no hais txog kev ua haujlwm siab ntawm Yankee dryer (chav tsev: kgf / cm², piv txwv li, kilogram-force ib square centimeter), lawv qhov sib txawv tseem ceeb yog pom tseeb hauv cov hauv qab no:
- Kub Ua Haujlwm Sib Txawv
Qhov cua sov ntawm Yankee cov tshuab ziab khaub ncaws feem ntau vam khom cov pa roj saturated sab hauv, thiab lub zog ntawm cov pa roj yog ncaj qha cuam tshuam nrog qhov kub thiab txias (ua raws li cov yam ntxwv ntawm cov pa roj):
Qhov kub ntawm cov pa roj saturated ntawm 3kgf / cm² (kwv yees li 0.3MPa) yog li 133 ℃;
Qhov kub ntawm cov pa roj saturated ntawm 5kgf / cm² (kwv yees li 0.5MPa) yog li 151 ℃.
Qhov sib txawv ntawm qhov kub thiab txias cuam tshuam ncaj qha rau qhov ua kom qhuav ntawm daim ntawv: qhov siab dua qhov siab (thiab yog li qhov kub thiab txias dua), qhov kub ntau dua raug xa mus rau daim ntawv ib lub sijhawm, ua rau qhov ziab sai dua. Qhov no ua rau nws haum rau cov ntawv uas xav tau kev ziab zoo (xws li daim ntawv so tes thiab cov tshuab ua ntawv ceev ceev).
- Kev Ua Kom Qhuav Zoo Sib Txawv thiab Kev Siv Hluav Taws Xob
Kev ua kom qhuav zoo: Lub tshuab ziab Yankee siab 5kgf/cm², nrog rau qhov kub siab dua, muaj qhov sib txawv ntawm qhov kub thiab txias dua nrog daim ntawv, ua rau muaj kev hloov pauv cua sov sai dua. Nws tuaj yeem ua kom cov dej noo ntau dua tib lub sijhawm thiab hloov kho rau qhov ceev ntawm lub tshuab ntawv.
Tus nqi siv zog: Cov pa roj ntawm 5kgf/cm² siab xav tau cov boiler tso zis ntau dua, ua rau siv zog ntau dua (xws li thee, roj av, thiab lwm yam). Cov pa roj ntawm 3kgf/cm² siab siv zog tsawg dua, ua rau nws tsim nyog rau cov xwm txheej uas qhov ceev ziab tsis tseem ceeb (xws li cov tshuab ntawv ceev qis thiab cov ntawv tuab).
- Cov Hom Ntawv thiab Cov Txheej Txheem Tsim Nyog
3kgf/cm² siab Yankee tshuab ziab khaub ncaws: Nrog qhov kub qis dua, nws tsim nyog rau cov ntawv rhiab heev rau cua sov (xws li qee cov ntawv waxed, cov ntawv nrog cov txheej uas yooj yim rau kev hloov pauv cua sov) lossis cov ntawv tuab dua uas xav tau kev ziab qeeb kom tsis txhob warping thiab tawg (xws li ntawv paperboard, ntawv kraft tuab).
5kgf/cm² siab Yankee lub tshuab ziab khaub ncaws: Nrog rau qhov kub siab dua, nws tsim nyog rau cov ntawv so ntswg (xws li ntawv xov xwm, ntawv sau), cov ntawv kab lis kev cai tsim tawm ntawm qhov ceev ceev, thiab lwm yam. Nws tuaj yeem tshem tawm cov dej noo sai sai, xyuas kom meej tias lub tshuab ntawv ua haujlwm tau zoo, thiab txo qhov kev pheej hmoo ntawm kev tawg ntawv los ntawm kev luv lub sijhawm nyob ntawm daim ntawv hauv cov txheej txheem ziab.
- Cov Kev Cai Sib Txawv rau Cov Khoom Siv thiab Kev Nyab Xeeb
Txawm hais tias ob qho tib si 3kgf/cm² thiab 5kgf/cm² siab yog cov hlab ntsha qis (feem ntau, qhov siab tsim ntawm Yankee lub tshuab ziab khaub ncaws siab dua qhov siab ua haujlwm nrog qhov kev nyab xeeb), qhov siab dua txhais tau tias qhov yuav tsum tau ua siab dua me ntsis rau lub zog ntawm cov khoom siv, kev ua haujlwm sealing, thiab phab ntsa tuab ntawm Yankee lub tshuab ziab khaub ncaws:
Cov khoom siv lub tog raj kheej ntawm 5kgf / cm² siab Yankee lub tshuab ziab khaub ncaws (xws li hlau cam khwb cia, hlau cam khwb cia hlau) yuav tsum ua kom ruaj khov nyob rau hauv qhov siab dua. Qhov tseeb ntawm kev ua cov vuam seams, flange seals, thiab lwm yam khoom yog nruj dua kom tsis txhob muaj pa tawm.
Ob qho tib si yuav tsum ua raws li cov cai tswjfwm kev nyab xeeb ntawm lub thawv siab, tab sis lub tshuab ziab khaub ncaws Yankee siab 5kgf / cm² yuav muaj kev tshuaj xyuas ntau zaus thiab nruj dua (xws li kev sim hydrostatic).
Kev Txheeb Xyuas
Cov tshuab ziab khaub ncaws Yankee uas muaj 3kgf/cm² thiab 5kgf/cm² feem ntau yuav kho qhov kub thiab txias kom qhuav los ntawm qhov sib txawv ntawm lub zog ntawm cov pa. Qhov sib txawv tseem ceeb yog qhov ceev ntawm kev ziab khaub ncaws, tus nqi siv hluav taws xob, thiab hom ntawv uas haum. Yuav tsum txiav txim siab seb puas yuav tsum xaiv raws li qhov ceev ntawm lub tshuab ntawv, cov yam ntxwv ntawm hom ntawv, cov peev nyiaj siv hluav taws xob, thiab lwm yam. Lub zog siab dua tsis yog qhov zoo dua; nws yuav tsum phim cov kev xav tau ntawm cov txheej txheem tsim khoom.
