Yuav ua li cas los daws qhov teeb meem thaum lub discharging ceev ntawm lub thawv ntim scale slows down?

Nyob rau hauv cov txheej txheem ntim khoom, qhov smoothness ntawm cov khoom tawm los ntawm lub thawv ntim ntim nplai (ton bag scale) ncaj qha cuam tshuam rau kev ua haujlwm ntawm tag nrho cov kab ntau lawm. Thaum cov neeg ua haujlwm pom tias lub ntim ntim tau dhau los ua qhov tsis zoo los yog cov khoom siv tsis zoo, qhov no feem ntau yog ib qho kev qhia tias kev ua haujlwm ntawm cov khoom siv, lub cev ntawm cov khoom siv, lossis cov xwm txheej ntawm cov khoom siv tshuab tau hloov pauv.
Hauv qhov xwm txheej no, peb tuaj yeem siv cov kauj ruam-los ntawm- kauj ruam mus kom ze, ua ntau- kev tshuaj xyuas qhov ntev thiab kev hloov kho los ntawm cov khoom siv mus rau cov khoom siv tshuab, txhawm rau rov ua haujlwm zoo ntawm cov khoom siv.
I. Kev cuam tshuam thiab kev hloov ntawm cov yam ntxwv ntawm cov khoom
Feem ntau, kev ua haujlwm qeeb ntawm cov khoom siv tsis yog vim kev puas tsuaj rau cov khoom siv nws tus kheej, tab sis qhov hloov pauv ntawm lub cev ntawm cov khoom siv.
1. Kev hloov pauv ntawm cov khoom siv av noo thiab viscosity: Yog tias cov hmoov los yog cov khoom siv granular yuav ntim tau tsis ntev los no tau raug ya raws, lossis muaj viscosity siab, nws muaj peev xwm tsim "bridging" tshwm sim ze ntawm qhov chaw nres nkoj tawm (uas yog, cov khoom raug thaiv ntawm lub qhov hluav taws xob thiab tsim ib qho kev sib tsoo ({1}).
• Kev tiv thaiv: Txheeb xyuas qhov chaw khaws cia ntawm cov ntaub ntawv thiab, yog tias tsim nyog, nruab cov khoom siv dehumidification ntxiv. Yog tias tus txheej txheem tso cai, xav txog qhov tsim nyog kho cov dej noo ntawm cov ntaub ntawv. Tsis tas li ntawd, ntxiv qhov tsim nyog ntawm cov tshuaj tiv thaiv -caking flow- pab cua cushions lossis cov khoom siv vibration hauv cov kab tawm ntawm cov ntim ntim tuaj yeem txhim kho cov dej ntws ntawm cov ntaub ntawv.
2. Particle loj thiab cov ntsiab lus roj: Cov khoom siv hmoov zoo yog qhov ua rau txhaws vim yog hluav taws xob zoo li qub adsorption lossis huab cua permeability tsis zoo; thaum hmoov cov ntaub ntawv uas muaj huab cua ntau yuav ntsib "gas resistance" thaum tawm mus.
• Kev tiv thaiv: Ua kom zoo dua cov plua plav tshem tawm kom ntseeg tau tias kev ua haujlwm zoo ntawm qhov tsis zoo ntawm ib puag ncig; los yog ntxiv cov txheej txheem tso pa ua ntej noj kom tshem tawm cov pa ntau dhau hauv cov ntaub ntawv.
II. Kev tshuaj xyuas ntawm Mechanical Cheebtsam 'Cov Cai
Cov khoom siv kho tshuab hauv lub ntim ntim yuav muaj kev hnav lossis hloov pauv mus rau lub sijhawm ntev ntawm kev ua haujlwm, uas tuaj yeem cuam tshuam rau kev pub mis ceev.
1. Tshem tawm qhov chaw nres nkoj thiab kev sib txuas yooj yim: Puas yog qhov loj ntawm qhov chaw nres nkoj tawm poob vim deformation? Puas yog cov kev sib txuas tau yooj yim ntawm cov ntsiab lus sib txuas (xws li cov raj roj hmab lossis cov hnab canvas) thinner, wrinkled, lossis txawm tias qee qhov sib tsoo thiab thaiv qhov kev hla vim yog kev sib txhuam ntev ntev?
• Cov tswv yim teb: Tom qab lub tshuab nres, manually xyuas qhov smoothness ntawm qhov chaw nres nkoj tawm, tshem tawm cov nplai los yog cov khoom seem uas txuas rau sab hauv phab ntsa. Tshawb xyuas thiab ncaj nraim cov kev sib txuas yooj yim, thiab hloov cov khoom hnyav hnyav yog tias tsim nyog los xyuas kom meej tias cov khoom siv dav dav thiab tsis muaj kev cuam tshuam.
2. Kev ua tau zoo ntawm cov cuab yeej tawg: Ntau qhov ntim ntim tau nruab nrog pneumatic arch - cov khoom tawg lossis cov khoom sib tov sib xyaw kom tawg muaj peev xwm thaiv tau thaum cov ntaub ntawv so.
• Cov tswv yim teb: Ua raws li kev ua haujlwm ntawm lub cuab yeej tawg, xyuas seb cov cua siab puas ua tau raws li tus qauv, thiab xyuas seb qhov kev tawm tsam puas tsim nyog. Xyuas kom meej tias lub ram tawg yog nyob rau hauv kev sib cuag nrog cov khoom thiab tuaj yeem ua tiav cov nyhuv loosening.
III. Optimization ntawm Control System Parameters
Automated ntim cov nplai feem ntau yog nruab nrog cov kev tswj hwm qib siab, thiab qhov kev teeb tsa ntawm qhov tsis ncaj qha cuam tshuam rau kev pub noj ceev.
Pub cov ntsia hlau sib hloov ceev: Teem qhov kev sib hloov ceev ntawm cov ntsia hlau conveyor qis dhau los tswj cov paug tawm yog qhov ncaj qha ua rau cov khoom tso tawm qeeb.
• Countermeasures: Thaum lub sij hawm kom ntseeg tau qhov tseeb ntawm ntim thiab ruaj khov ntawm qhov hnyav, sim ua kom nruab nrab ntawm qhov chaw ceev ntawm lub hau ntswj. Ua tib zoo mloog cov lus tawm tswv yim los ntawm qhov ntsuas qhov ntsuas kom tsis txhob muaj qhov nrawm nrawm nrawm vim qhov nrawm nrawm thiab cov khoom txhaws.
2. Hloov qhov taw tes rau kev pub noj sai thiab qeeb: Cov nplai ntim ntim feem ntau yog siv ob qho - ceev tswj hom "fast feeding + slow feeding". Yog tias qhov kawg ntawm qhov pib (hloov taw tes) rau kev pub noj ceev yog teem tsis raug, nws yuav ua rau cov cuab yeej nyob twj ywm hauv qis - lub xeev ua haujlwm ceev rau lub sijhawm ntev.
• Countermeasures: Re-calibrate lub ntsuas qhov hnyav thiab kho qhov ntsuas qhov ntsuas raws li cov yam ntxwv ntawm cov khoom. Sim me ntsis ua ntej qhov kawg ntawm kev pub noj sai, tso cai rau cov khoom siv khiav ntawm kev kub ceev rau lub sijhawm ntev, yog li txhim kho tag nrho cov khoom noj kom zoo.
IV. Kev kho ntawm Pneumatic System
Rau cov nplais ntim uas siv pneumatic actuators (xws li pneumatic rooj vag li qub thiab npauj npaim li qub), kev huv huv ntawm huab cua thiab kev ruaj ntseg ntawm huab cua siab yog qhov tseem ceeb tshaj plaws.
• Cov tswv yim teb: Tshawb xyuas cov kev ua haujlwm ntawm lub tshuab cua compressor thiab xyuas kom meej tias huab cua txoj kev triad (filter, siab txo valve, roj av generator) ua haujlwm li qub. Tsis tu ncua tso cov dej condensate los ntawm lub lim thiab ntxiv cov roj lubricating rau lub tog raj kheej kom tiv thaiv cov li qub los ntawm kev daig thiab tsis tuaj yeem qhib tag nrho, yog li ua kom cov ntaub ntawv du.
Los ntawm cov kev tshawb fawb saum toj no los ntawm sab hauv tawm thiab los ntawm qhov muag mus rau qhov nyuaj, feem ntau nws yog qhov ua tau los txheeb xyuas qhov tshwj xeeb ntawm qhov ua rau qeeb ntawm qhov tso tawm ntawm lub hnab ntim ntim. Hauv kev tsim khoom tiag tiag, nws raug nquahu kom tsim kom muaj kev tshuaj xyuas cov cuab yeej tsis tu ncua thiab cov txheej txheem kaw lus kom pom qhov txawv txav sai sai thiab ua kom muaj kev tiv thaiv kev saib xyuas, ua kom lub sijhawm ntev - lub sijhawm ua haujlwm ruaj khov ntawm cov kab ntau lawm.
