1.Definition thiab Function

Lub thawv ntim tau tuav txoj haujlwm tseem ceeb hauv kev lag luam papermaking thiab yog ib qho tseem ceeb ntawm cov ntawv tshuab. Nws lub luag haujlwm tseem ceeb yog txhawm rau faib cov ntaub ntawv npaj rau hauv seem xaim ntawm lub tshuab ntawv nyob rau hauv ib qho zoo, ruaj khov, thiab tswj tau. Los ntawm kev tswj xyuas tus nqi txaus, qhov ntim ntim, thiab kev faib cov fiber ntau ntawm cov ntaub so ntswg, lub thawv ntws tso rau hauv lub hauv paus rau kev tsim cov ntawv txuas ntxiv thiab cov ntaub ntawv ntub dej zoo ib yam, uas ua lub luag haujlwm txiav txim siab hauv qhov zoo thiab kev ua haujlwm ntawm daim ntawv kawg. .

2.Basic Cheebtsam

Lub Cev Lub Cev: Raws li cov qauv tseem ceeb ntawm lub thawv ntws, nws feem ntau yog ua los ntawm cov khoom siv hlau muaj zog xws li cov hlau tsis muaj steel lossis cov hlau zoo hlau. Nws tsis tsuas yog yuav tsum tau muab qhov chaw txaus kom haum rau lub pulp tab sis kuj yuav tsum muaj peev xwm tiv taus lub siab tsim los ntawm cov ntaub so ntswg sab hauv thiab cov neeg kho tshuab kev ntxhov siab los ntawm ib puag ncig sab nraud. Kev tsim thiab kev tsim khoom zoo ntawm lub thawv lub cev ncaj qha cuam tshuam rau tag nrho kev ruaj ntseg thiab kav ntev ntawm lub thawv ntws.

Pulp Distributor: Qhov no yog ib feem tseem ceeb los xyuas kom meej qhov kev faib tawm ntawm cov pulp nyob rau hauv cov kev taw qhia ntawm lub tshuab. Los ntawm kev ua tib zoo tsim cov channel thiab cov khoom xa tawm, nws sib npaug faib cov khoom xa tuaj thoob plaws tag nrho cov tshuab dav dav. Qhov kev ua tau zoo ntawm cov khoom siv pulp ncaj qha txiav txim siab qhov sib xws ntawm cov ntaub so ntswg nyob rau hauv qhov kev taw qhia ntawm lub tshuab ntoo khaub lig, yog li cuam tshuam lub hauv paus hnyav thiab thickness uniformity ntawm daim ntawv nyob rau hauv cross-tshuab kev taw qhia.

Rectification Elements: suav nrog homogenizing rolls, turbulence generators, thiab lwm yam. Lub homogenizing rolls do thiab homogenize lub pulp los ntawm kev sib hloov, tshem tawm tej zaum hauv zos concentration sib txawv thiab fiber ntau agglomeration. Cov turbulence generators tsim turbulence tsim nyog los txhawb cov dispersion thiab sib tov ntawm fibers thaum tsis txhob turbulence ntau heev uas ua rau fiber ntau flocculation los yog kev puas tsuaj rau cov fibers. Cov ntsiab lus rectification no ua haujlwm ua ke los coj cov ntaub so ntswg mus rau lub xeev zoo tagnrho ua ntej nkag mus rau hauv seem hlau, yog li ua kom cov ntawv zoo thiab ua haujlwm tau zoo.

Daim di ncauj: Nyob ntawm qhov hluav taws xob ntawm lub thawv ntws, cov duab thiab qhov qhib ntawm daim di ncauj ncaj qha tswj qhov nrawm thiab lub kaum sab xis ntawm lub pulp yog ejected mus rau seem hlau. Los ntawm kev kho qhov qhib thiab cov duab ntawm daim di ncauj, kev tswj xyuas meej ntawm qhov chaw tsaws thiab ejection ceev ntawm cov ntaub so ntswg ntawm cov xov hlau tuaj yeem ua tiav, yog li cuam tshuam rau kev tsim thiab cov yam ntxwv zoo ntawm daim ntawv.

3. Txoj Cai Ua Haujlwm

Lub pulp yog thawj zaug nkag rau hauv lub thawv lub cev ntawm lub thawv ntws. Tom qab kev faib tawm tsis sib xws los ntawm cov khoom siv pulp, nyob rau hauv qhov kev txiav txim ntawm cov ntsiab lus rectification, turbulence thiab non-uniformity raug tshem tawm, thiab lub pulp ncav cuag ib tug ruaj khov thiab uniform flow xeev. Thaum kawg, los ntawm kev tswj xyuas meej ntawm daim di ncauj, nws yog ejected mus rau hauv seem xaim ntawm daim ntawv tshuab ntawm ib qho kev ceev thiab lub kaum ntse ntse, thiab ib daim ntawv ntub dej yog tsim nyob rau hauv qhov pom thiab dewatering kev txiav txim ntawm cov hlau seem.

4.Performance Parameters

Flow Rate Control Accuracy: Txiav txim siab lub hauv paus hnyav sib xws thiab fiber ntau faib uniformity nyob rau hauv tus ntoo khaub lig-tshuab kev taw qhia ntawm daim ntawv.

Flow Volume Stability: Ua kom muaj kev ruaj ntseg ntawm daim ntawv zoo thaum lub sij hawm tsim khoom thiab txo cov ntawv tsis xws luag los ntawm qhov ntws ntim hloov pauv.

Fiber Dispersion Effect: Cov fiber ntau dispersion zoo tuaj yeem txhim kho lub zog thiab sib xws ntawm daim ntawv.

5.Kev tu thiab tu

Kev Tu Tsis tu ncua: Tshem tawm cov khib nyiab, impurities, thiab fiber ntau residues hauv lub thawv lub cev kom tiv thaiv kev txhaws thiab cuam tshuam rau kev ntws ntawm cov tawv nqaij.

Kev Tshuaj Xyuas Cheeb Tsam: Tsis tu ncua tshuaj xyuas cov khoom tseem ceeb xws li cov khoom siv hluav taws xob, cov khoom siv kho kom zoo, thiab daim di ncauj kom ntseeg tau tias tsis hnav, deformation, lossis puas.

Calibration thiab Kho: Tsis tu ncua calibrate thiab kho cov tsis xws li txaus tus nqi, ntws ntim, thiab di ncauj phaj qhib kom ntseeg tau tias qhov kev ua tau zoo ntawm lub thawv ntws yog ib txwm nyob rau hauv qhov zoo tshaj plaws lub xeev.

6.Kev xaiv thiab daim ntawv thov

Thaum xaiv lub thawv ntws, kev txiav txim siab dav dav yuav tsum tau ua raws li cov yam ntxwv xws li hom ntawv tshuab, ntau yam thiab cov lus qhia tshwj xeeb ntawm cov ntawv tsim, cov khoom nrawm, thiab cov kev xav tau zoo. Cov thawv ntim sib txawv (xws li hom qhib, hom cua cushion, hom hydraulic, thiab lwm yam) muaj cov yam ntxwv ntawm kev ua haujlwm sib txawv thiab daim ntawv thov. Piv txwv li, rau high-speed, high-quality ntawv ntau lawm, ib tug txaus lub thawv nrog ntau tshaj kev tswj technology thiab siab dua precision yuav raug xaiv; thaum rau kev tsim cov ntaub ntawv zoo tib yam, yuav xaiv cov qauv kev lag luam ntau dua thiab siv tau.
