Dab ntxwg nyoog buzzing ntawm dampening rollers thiab number case piling? Tsuas pom lub hauv paus ntawm qhov kub thiab txias sib txawv.
Hauv qhov chaw luam ntawv sab hauv tsev nrog qhov kub ntawm 20 degree, thaum Heidelberg xovxwm ceev tau nce mus rau ntau dua 12,000 nplooj ntawv hauv ib teev, cov neeg ua haujlwm tau pom qhov txawv 'buzzing' suab los ntawm cov dampening rollers, nrog rau cov qauv yoj thiab hauv zos number case piling ntawm cov menyuam nto. Kev tshuaj xyuas thawj zaug tsis pom cov khoom siv hluav taws xob lossis cov khoom siv xoob xoob, thiab nws tau txiav txim siab tias qhov teeb meem yog tshwm sim los ntawm kev ua haujlwm tsis zoo ntawm cov tshuab luam ntawv.
Teeb meem tsom xam thiab daws teeb meem txheej txheem
01/ Cov Kev Ntsuas Thaum Ntxov
Txhawm rau txhim kho cov kua dej ntawm tus number case, cov dej kub ntawm lub hauv paus system tau hloov kho thawj zaug ntawm 8 txog 12 degrees. Nyob rau hauv txoj kev xav, qhov nruab nrab nce tus ciav dej kub tuaj yeem txhim kho tus lej hloov pauv kev ua tau zoo, tab sis hauv kev xyaum nws tsuas yog txhim kho tus cwj mem fluidity me ntsis, nrog rau cov piling ntawm tus number case nyob ze ntawm cov menyuam dej thiab cov qauv rippling tsuas yog me ntsis relieved.
02/ Nyob rau hauv -Qhov Kev Ntsuas Qhov Ntsuas
Los ntawm kev soj ntsuam kaw thiab ntau qhov kev soj ntsuam, cov hauv paus ntsiab lus ntawm qhov teeb meem tau txheeb xyuas raws li hauv qab no:
(1) Tus ciav dej kub qis dhau lawm: Cov kua roj hmab (tshwj xeeb tshaj yog daim ntawv chais) yog nyob rau hauv kev sib cuag nrog qis -kub qhov hluav taws xob, ua rau lawv qhov kub thiab txias poob qis, cov roj hmab txheej kom tawv, thiab elasticity kom txo, ua rau cov kua dej tsis sib xws. Thaum tus number case rollers hu rau lub phaj, "slipping" lossis "tsis txaus shearing" tshwm sim, tiv thaiv kom tsis txhob muaj cov number case stripping thiab ua rau cov number case khaws cia thiab khaws cia.
(2) Daim pam kub siab dhau: Vim lub sij hawm ntev heev -kev khiav hauj lwm ceev ntawm lub tshuab luam ntawv, daim pam generates tshav kub los ntawm kev sib txhuam, ua rau nws kub thiab tsim ib tug tseem ceeb kub txawv nrog rau qhov qis - kub number case rollers, ua rau lub viscosity imbalance thaum hloov number case. Tus cwj mem tsis tuaj yeem hloov pauv los ntawm lub phaj mus rau daim pam, ua rau ib feem ntawm tus number case rov qab los yog tsub zuj zuj nyob ze ntawm qhov chaw cov menyuam.
(3) Kev ntxhov siab tsis sib xws ua rau cov dej tsis zoo rau cov menyuam yaus: Cov menyuam cov dej rov ua rau cov menyuam txias thiab cov pam sov, ua rau cov thermal expansion thiab contraction tsis sib xws, uas ua rau muaj kev vibration thiab humming suab nrov, thaum tseem tsim cov rippled number case rau saum npoo.
Kev daws teeb meem thiab kev siv
Lub tswv yim tseem ceeb ntawm txoj kev daws teeb meem yog kom sib npaug ntawm qhov sib txawv ntawm qhov kub thiab txias hloov pauv, hloov qhov kev hloov kho kom pom tseeb los ntawm "tsuas yog nce dej kub" mus rau "tswj daim pam kub thiab ua tiav qhov system thermal tshuav." Cov kev ntsuas tshwj xeeb yog raws li hauv qab no:
(1) Kho cov huab cua ntim: Hauv qhov kev teeb tsa thawj zaug, kom muaj kev ruaj ntseg luam ntawv, daim pam cheeb tsam daim ntawv - cua siab nyob rau hauv lub xeev kaw tag nrho. Tam sim no, lub pam txias cua channel qhib 30% ~ 50% siv cua convection rau maj mam txias, aiming kom txo tau qhov kub ntawm daim pam los ntawm lub overheated lub xeev saum toj no 45℃mus rau ib tug zoo tagnrho ua hauj lwm ntau yam ntawm 38 ~ 42 degree.
(2) Saib xyuas tus number case rau cov menyuam kub: Siv lub ntsuas kub infrared los saib xyuas qhov kub thiab txias ntawm daim ntawv yob hauv lub sijhawm, xyuas kom nws tsis poob qis dua 28 degree. Yog tias tsim nyog, tus number case roller cua sov system tuaj yeem qhib lossis hloov kho qhov kub thiab av noo ib puag ncig. Lub qhov dej ntsuas kub tau rov qab los rau 10℃(qhov zoo tshaj qhov ntsuas qhov ntsuas) kom tsis txhob muaj dej kub ntau dhau ua rau cov kua nplaum emulsification.
Thaum kawg, ua tib zoo ntxuav daim ntawv foos rau cov menyuam thiab tus cwj mem, tshem tawm cov ntawv sau thiab cov crusting, thiab rov ua kom lub zog ntawm cov dej thiab cov kua nplaum kom paub meej tias kev sib cuag. Khiav cov xovxwm ntawm qis ceev rau 10 feeb kom paub meej tias tsis muaj lub suab txawv txav lossis rippling, ces maj mam nce nrawm mus rau 15,000 nplooj / teev.
Kev siv cov nyhuv
Cov teebmeem ntawm kev siv tau muaj nyob rau hauv cov lus hauv qab no:
Technical Principles thiab Experience Summary
Thermal equilibrium yog tus yuam sij rau siab - ceev luam ntawv. Nyob rau hauv siab - luam ntawv ceev, tus number case hloov pauv tsis yog nyob ntawm qhov siab thiab ntub dej xwb tab sis kuj cuam tshuam zoo heev los ntawm qhov kub thiab txias. Yog hais tias tus number case yog txias dhau, nws yuav ua rau elasticity poob thiab hloov tus number case tsis zoo; Yog tias daim pam kub dhau, tus number case viscosity yuav txo qis, thiab kev hloov pauv yuav tsis tiav. Tsuas yog los ntawm kev ua tiav qhov sib npaug ntawm qhov kub thiab txias thiab tsis txhob muaj qhov sib txawv ntawm qhov kub thiab txias hauv zos tuaj yeem ua kom ruaj khov.
Tsis tas li ntawd, kev xav hauv lub cev yog qhov zoo tshaj rau kev kho ib qho kev txwv. Tsuas yog nce dej kub tsis tuaj yeem daws qhov teeb meem; Ntawm qhov tsis sib xws, nws tuaj yeem ua rau lub cev tsis txaus. Kev sib koom tes yuav tsum tau ua nyob rau hauv ntau qhov ntev, nrog rau cov dampening system, ink path system, pam vov, thiab ib puag ncig.
Qhov teeb meem daws teeb meem no qhia tau tias nyob rau hauv siab - ua haujlwm ceev (15,000 nplooj / teev) ntawm Heidelberg luam ntawv xovxwm, suab nrov txawv txav los ntawm lub phaj dampening roller thiab number case piling tsis yog tsuas yog cov khoom siv los yog lubrication. Lawv tau tshwm sim los ntawm qhov systemic thermodynamic tsis txaus vim qhov kub thiab txias ntawm tus number case roller thiab siab kub ntawm daim pam. Los ntawm kev qhib daim pam daim ntawv siab cua duct kom ua tiav qhov txias txias, ib txwm hloov pauv tus cwj mem tau rov qab zoo, tshem tawm tag nrho cov xwm txheej txawv txav.
Nyob rau hauv siab - luam ntawv ceev, nws yog ib qho tsim nyog tsis yog rau 'kho dej thiab number case' xwb, tab sis kuj yog 'kho qhov kub thiab txias.' Qhov ntsuas kub sib npaug yog qhov pom tsis pom ntawm kev luam ntawv ruaj khov.
