Nyob rau hauv lub tshuab ntim khoom ntim khoom siv rau lub hnab ntim (cov thawv ntim khoom), cov txheej txheem ntim khoom nquag ntsib cov khoom sib tsoo (feem ntau hu ua "bridge tsim"), uas tsis yog tsuas yog txo qis kev tsim khoom tab sis kuj ua rau cov khoom siv txawv txav thiab tseem ua rau kev ua tsis tiav. Thaum lub ntim ntim tau ntsib teeb meem hauv cov ntaub ntawv pov tseg, tsis sib xws los yog ua tiav stagnation thaum lub sij hawm ntim cov txheej txheem, nws feem ntau tsis tshwm sim los ntawm ib qho, tab sis qhov tshwm sim los ntawm kev sib xyaw ua ke ntawm cov khoom siv lub cev, cov khoom siv kev ua haujlwm, thiab kev teeb tsa.
Hauv qab no, los ntawm plaub qhov loj me, peb yuav ua cov ncauj lus kom ntxaws rau koj ntawm cov laj thawj uas ua rau cov khoom siv tsis tu ncua hauv cov nplai ntim thiab cov kev daws teeb meem sib xws:
1. Lub cev lub cev thiab cov xwm txheej ntawm cov ntaub ntawv lawv tus kheej muaj kev cuam tshuam.
Cov khoom ntawm cov ntaub ntawv yog qhov tseem ceeb ntawm qhov nyuaj ntawm kev txiav cov khoom. Feem ntau, cov qauv ua ntej -kev kho mob rau cov khoom siv los ntawm cov kab ntau lawm txawv ntawm cov khoom siv tiag tiag.
• Moisture cov ntsiab lus thiab viscosity hloov: Qhov no yog ib qho tshwm sim heev. Yog hais tias cov dej noo ntawm cov khoom yog siab dhau lawm, los yog cov khoom muaj zog adsorption thiab viscosity, nws muaj peev xwm tsim clumps thiab lo ua ke nyob rau hauv lub silo los yog lub hopper. Raws li qhov loj ntawm cov clumps nce, nws yuav thaiv cov kab tawm tawm.
• Particle puab thiab hardness: cov khoom hais tsis zoo nyob rau hauv cov duab, heev finely crushed, los yog muaj siab hardness nrog ntse npoo. Thaum muaj kev sib txhuam thiab cov txheej txheem sib xyaw ua ke, lawv yooj yim tsim cov qauv arched (piv txwv li, "bridges").
• Electrostatic adsorption effect: Qee cov khoom hnyav thiab cov hmoov qhuav yog nquag tsim hluav taws xob zoo li qub thaum lub sijhawm siab - nrawm nrawm thiab kev sib txhuam, ua rau cov ntaub ntawv ua raws cov phab ntsa sab hauv ntawm lub silo lossis cov phab ntsa sab hauv ntawm qhov chaw nres nkoj tawm, ua rau cov paug tawm tsis zoo.
II. Mechanical Structure ntawm cov cuab yeej siv thiab hnav cov yam ntxwv ntawm cov khoom
Yog hais tias cov khoom siv kho tshuab ntawm lub ntim ntim tau dhau los lossis hnav tawm, lawv yuav cuam tshuam ncaj qha rau cov khoom noj khoom haus qub.
• Kev ua kom tsis zoo ntawm qhov kev sib tsoo / xa tawm qhov ua tau zoo: Feem ntau tuj- cov nplais tam sim no tuaj nrog pneumatic so 拱 cov khoom siv lossis cov tshuab ua kua dej. Yog tias huab cua siab ntawm cov khoom siv pneumatic tsis txaus, muaj cov xau hauv cov raj xa dej, lossis cov cua vents ntawm cov phaj fluidization raug thaiv los ntawm cov khoom txawv teb chaws, cov ntaub ntawv yuav tsis muaj peev xwm ua kom muaj dej txaus, thiab nws muaj peev xwm ua rau cov khoom siv tuag.
• Hnav cov ntaub ntawv sab hauv thiab qhov chaw nres nkoj tawm: Tom qab ua haujlwm ntev - lub sijhawm ua haujlwm, cov phab ntsa sab hauv ntawm lub silo lossis daim duab peb sab - thaj chaw zoo li ntawm qhov chaw nres nkoj tawm tuaj yeem hnav thiab deformation, ua tsis sib xws. Qhov saum npoo ntxhib no yuav ua rau muaj kev sib txhuam ntawm cov ntaub ntawv, tsim kom muaj chaw yug me nyuam rau cov khoom thaiv.
• Kev sib txuas tsis zoo ntawm kev hloov pauv: Cov kev sib txuas muag muag (xws li lub hnab roj hmab hloov tau yooj yim) nruab nrab ntawm lub hopper thiab lub hnab ntim qis lossis qhov chaw noj mov yuav luv dhau, tsis tsim nyog, lossis muaj creases. Thaum cov khoom ntog ntawm kev kub ceev, nws yuav raug thaiv lub cev.
III. Tswj System Parameters thiab Logic Settings
Yog tias tsis muaj cov cuab yeej siv hluav taws xob tsis raug teeb tsa raws li cov khoom siv tiag tiag, nws feem ntau ua rau cov cuab yeej ua haujlwm ntawm "ntug ntawm qhov teeb meem".
• Kev tsis txaus ntseeg ntawm kev pub mis: Qhov kev pub mis ceev feem ntau yog muab faib ua ob theem: nrawm ntxiv thiab qeeb ntxiv. Yog hais tias qhov ceev ntxiv theem yog kaw ntxov dhau, cov khoom yuav tsis tau compactly piled rau hauv qab; los yog yog hais tias qhov qeeb ntxiv theem teb sluggishly, uas ua rau ib qho kev poob siab ntau dhau ntawm qhov hluav taws xob tawm, nws tuaj yeem hloov cov qauv ntws ntawm cov khoom.
• Pneumatic valve ua lag luam: Rau cov npauj npaim li qub los yog lub rooj vag li qub uas tswj cov kev tawm tswv yim thiab cov zis, yog tias lub tog raj kheej teb ceev qeeb, qhov qhib tsis tiav (muaj ib nrab - qhib qhov chaw tuag), los yog lub tshuab hluav taws xob valve yog qeeb hauv cov lus teb, nws yuav ua rau muaj kev cuam tshuam hauv cov zis channel.
• Qhov hnyav sensor teeb liab cuam tshuam: Yog tias lub sensor cuam tshuam los ntawm kev co sab nraud lossis yog tias lub lim dej coefficient raug teeb tsa tsis raug, nws yuav ua rau lub ntsuas ntsuas ntsuas qhov siab ntawm cov khoom siab thiab txiav tawm qhov kev txiav txim tawm ntxov ntxov.
IV. Cov yam ntxwv ntawm Ntawm -site Ib puag ncig thiab cov txheej txheem ua haujlwm
Cov kev hloov me me hauv ib puag ncig tsim khoom feem ntau raug saib xyuas, tab sis lawv feem ntau ua rau muaj kev cuam tshuam tsis sib xws.
• Ib puag ncig qhov kub thiab av noo hloov pauv: tshwj xeeb tshaj yog nyob rau lub caij nyoog nrog qhov kub thiab txias sib txawv thaum sawv ntxov thiab yav tsaus ntuj, cov dej condensation yuav tsim nyob rau hauv lub silo. Qhov no yuav hloov lub micro- ib puag ncig ntawm cov ntaub ntawv tam sim ntawd, ua rau cov ntaub ntawv uas yav dhau los ua kom nrawm nrawm.
• Cov huab cua tsis zoo: Lub tshuab pneumatic ntawm lub ntim ntim muaj cov kev cai nruj rau huab cua zoo. Yog hais tias cov dej noo nyob rau hauv compressed cua muab los ntawm cov cua compressor siab dhau lawm, nws yuav tsis tsuas corrode lub li qub, tab sis kuj khov nyob rau hauv lub solenoid li qub los yog lub tog raj kheej nyob rau hauv qis - kub ib puag ncig, ua rau lub li qub malfunction.
• Kev coj tus cwj pwm ua haujlwm: Thaum lub sij hawm thauj khoom thiab rov ua cov khoom muag, yog tias tus neeg teb xov tooj tsis ua txhaum cov ntaub ntawv loj ua ntej muab tso rau hauv, lossis yog tias lub loader nqa cov khoom loj txawv teb chaws thaum khawb cov khoom, cov khoom loj no feem ntau yuav daig saum lub qhov hluav taws xob tawm.
V. Cov lus qhia txog kev tshawb nrhiav thiab kev ua kom zoo
Raws li cov laj thawj saum toj no, cov kev ntsuas hauv qab no raug pom zoo rau kev tshawb xyuas qhov systematic:
Kev tswj qhov chaw: Txhim kho cov khoom siv los soj ntsuam, nruj me ntsis tswj cov dej noo thiab particle loj faib ntawm cov ntaub ntawv; yog tias tsim nyog, ntxiv cov cuab yeej pabcuam xws li kev quab yuam nplawm lossis ziab kom qhuav ntawm qhov kawg ntawm cov kab ntau lawm.
2. Kev saib xyuas txhua yam: tsis tu ncua txhuam cov phab ntsa sab hauv ntawm lub silo, tshuaj xyuas thiab tshem tawm cov cua nkag rau dislodging lub damper; hloov cov khaub ncaws hnyav hnyav thiab cov khoom siv hluav taws xob; xyuas kom meej tias qhov kev sib txuas mos yog nyob rau hauv ib txwm so.
3. Parameter fine-tuning: Sim kho qhov kev pub mis ceev nkhaus, tsim nyog ncua sij hawm ntawm lub sij hawm noj qeeb, thiab txo qhov cuam tshuam ntawm qhov poob ntawm qhov pib; xyuas thiab calibrate qhov qhib℃ntawm li qub.
4. Kev ruaj ntseg ib puag ncig: Txhim kho cua kom qhuav cov ntxaij lim dej kom ntseeg tau tias huab cua siv los ntawm cov khoom siv pneumatic yog huv si thiab qhuav; tswj qhov cua kom zoo nyob rau hauv lub rhiav kev tsim khoom kom txo tau cov plua plav thiab qhov cuam tshuam ntawm cov dej noo.
Los ntawm kev ua tiav kev kuaj mob los ntawm plaub yam ntawm cov khoom siv, cov khoom siv, tsis muaj thiab ib puag ncig, nws feem ntau tuaj yeem txheeb xyuas qhov tseeb ntawm lub hauv paus ua rau muaj teeb meem jamming hauv lub hnab ntim cov nplai, yog li rov ua haujlwm du ntawm cov kab ntau lawm.
