Khiav lub auger sai dua tsis tau zoo dua. Kev nrawm dua tuaj yeem ua rau muaj peev xwm ntau lawm, tab sis nws kuj tuaj yeem ua rau cov txheej txheem tshuaj ntau nyuaj rau kev tswj xyuas qee cov hmoov.
Ib txoj hauv kev zoo dua yog nrhiav kev ua haujlwm ruaj khov nyob rau hauv uas cov hmoov ntws tsis tu ncua thiab kev siv tshuaj tuaj yeem teb tau zoo.
Rau kev tsim khoom tsis siv neeg, lub tshuab tuaj yeem siv cov theem sib txawv los yog tswj cov tswv yim kom ncav cuag lub hom phiaj hnyav dua. Ib theem ntxhib puv tuaj yeem txav mus rau feem ntau ntawm cov khoom sai sai, ua raws li theem kev noj tshuaj zoo dua thaum lub hom phiaj mus txog.
Lub tswv yim tswj xyuas yog nyob ntawm lub tshuab tsim thiab kev ua kom tiav.
Calibrate thiab tuav lub Weighing System
Thaum lub tshuab filling siv lub tshuab hnyav, cov khoom hnyav dhau los ua ib feem tseem ceeb ntawm cov saw hlau raug.
Lub ntsuas tsuas tuaj yeem muab cov lus qhia txhim khu kev qha yog tias lub xov tooj ntawm tes, qhov hnyav, kev sib txuas hluav taws xob, thiab cov khoom sib txuas tau raug ntsia, ntsuas, thiab tswj xyuas.
NIST Phau Ntawv 44 qhia txog qhov tseem ceeb ntawm qhov raug thiab rov ua dua qhov hnyav thiab muab cov kev cai rau kev ntsuas thiab ntsuas cov cuab yeej. Tam sim no tsab 2026 tseem muab cov txheej txheem rau kev ntsuas qhov tsim nyog, raug, thiab rov ua kom zoo sib xws ntawm cov khoom hnyav.
Rau cov khoom ntim khoom lag luam, calibration yuav tsum tsis txhob raug kho raws li ib qho - lub sijhawm teeb tsa. Lub cev hnyav yuav tsum tau kuaj xyuas ib ntus thiab thaum twg muaj kev hloov pauv tseem ceeb hauv cov khoom siv, cov khoom, lossis kev ua haujlwm.
Yog hais tias qhov hnyav tawm tswv yim tsis ruaj khov, hloov lub auger ceev ib leeg yuav tsis daws qhov teeb meem hauv qab.
Txo cov hmoov txhuam hniav thiab tsis sib xws
Hmoov tsis zoo yog ib qho laj thawj rau kev noj tshuaj tsis sib xws.
Cov hmoov sib xyaw ua ke tuaj yeem tsim cov txuas txuas hauv lub hopper, thaum lwm cov hmoov tuaj yeem tsim cov nas tsuag -holing los yog tsis sib xws. Cov xwm txheej no tuaj yeem ua rau lub tshuab pub mis kom tau txais cov khoom siv tsis sib xws.
Kev tshawb fawb tau pom tias cov hmoov ntws yog nyob ntawm cov khoom siv thiab kev ua haujlwm, nrog rau cov dej noo, qhov kub thiab txias, tus nqi zoo li qub, aeration, thiab keeb kwm ntawm kev ntxhov siab.
Cov kev daws teeb meem yuav suav nrog hopper agitators, tshwj xeeb tsim hopper geometries, tswj kev noj zaub mov, tshuab kev co, lossis lwm yam khoom siv khiav - pab.
Txawm li cas los xij, cov khoom siv no yuav tsum tau xaiv kom zoo. Excessive vibration or agitation can sometimes change powder density or promote segregation, so simply adding more mechanical movement is not necessarily the correct solution.
Tswj Hmoov Segregation
Kev sib cais hmoov tuaj yeem tsim lwm hom kev hloov pauv.
Yog tias cov hmoov sib xyaw muaj cov khoom sib txawv, qhov ntom ntom, lossis lwm yam ntawm lub cev, kev tuav thiab kev xa khoom tuaj yeem ua rau cov khoom sib cais. Qhov no tuaj yeem hloov cov yam ntxwv ntawm cov khoom mus txog lub tshuab filling.
Rau cov khoom uas formulation uniformity yog ib qho tseem ceeb, tswj cov ntaub ntawv txoj kev los ntawm cia mus filling yog li ntawd tseem ceeb heev.
Kev noj zaub mov, kev hloov khoom siv, kev tsim lub hopper, thiab kev ua haujlwm yuav tsum raug suav tias yog ib qho txheej txheem es tsis yog cov tshuab ywj pheej.
Txo kev vibration thiab sab nraud cuam tshuam
Mechanical vibration tuaj yeem cuam tshuam qhov hnyav ruaj khov, tshwj xeeb tshaj yog thaum lub tshuab filling tso siab rau ntawm lub xov tooj ntawm tes los txiav txim siab qhov kawg ntim qhov hnyav.
Nyob ze conveyors, motors, ntim tshuab, los yog cov qauv kev co tuaj yeem ua rau muaj kev cuam tshuam rau lub teeb liab. Yog li ntawd, lub platform hnyav yuav tsum tau muab cais tawm raws li qhov tsim nyog rau cov khoom tsim.
Tib txoj cai siv rau cov tshuab pneumatic. Cov huab cua tsis ruaj tsis khov lossis tswj tsis raug pneumatic Cheebtsam tuaj yeem cuam tshuam cov khoom txav thiab, hauv qee qhov kev siv, hmoov coj cwj pwm.
Ib puag ncig ruaj khov thiab pneumatic ib puag ncig ua rau nws yooj yim dua rau kev tswj hwm kom paub qhov txawv ntawm cov khoom hnyav los ntawm kev cuam tshuam sab nraud.
Siv cov khoom siv -Tshwj xeeb Machine Settings
Tsis muaj universal tshuab teeb tsa uas muab tib lub filling raug rau txhua tus hmoov.
Two products with the same target weight may behave very differently because their bulk density, flowability, particle size, moisture content, and cohesion are different.
Vim li no, muaj cov hmoov filling tshuab yuav tsum tau sim siv cov khoom tiag tiag thaum twg los tau.
Cov txheej txheem ua haujlwm ua haujlwm yuav tsum ntsuas qhov ua tiav raws li cov txheej txheem tsim khoom thiab tom qab ntawd kho qhov cuam tshuam raws li ntsuas kev ua tau zoo.
OIML R 61, uas suav nrog cov khoom siv gravimetric tsis siv neeg puv, kuj lees paub tias qhov kev xav tau raug cuam tshuam nrog rau cov khoom xws li cov khoom raug hnyav, kev teeb tsa, kev sau nqi, thiab kev khiav hauj lwm tus nqi.
Saib xyuas qhov tseeb thaum tsim khoom
Kev ua tiav qhov raug zoo thaum lub tshuab ua haujlwm tsuas yog ib feem ntawm txoj haujlwm.
Kev tsim khoom tuaj yeem hloov pauv raws sijhawm. Cov hmoov tuaj yeem los ntawm cov khoom sib txawv, qhov chaw nyob ib puag ncig yuav hloov pauv, cov khoom siv yuav hnav, lossis cov khoom siv thiab cov khoom noj yuav txawv.
Kev kuaj xyuas ntau lawm tuaj yeem pab txheeb xyuas cov kev hloov pauv no ua ntej lawv dhau los ua teeb meem loj.
Es tsis txhob saib tsuas yog qhov nruab nrab qhov hnyav hnyav, cov tuam txhab tsim khoom yuav tsum tau them sai sai rau kev faib tawm ntawm tus neeg sau cov txiaj ntsig. Cov txheej txheem ruaj khov yuav tsum tsim cov txiaj ntsig uas nyob ib puag ncig ze rau lub hom phiaj es tsis yog qee zaus ua qhov sib txawv loj.
Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum cov txheej txheem filling yog khiav ntawm kev kub ceev.
Match Machine Capacity rau Daim Ntawv Thov
Lwm qhov yuam kev yog xaiv lub tshuab raws li nws qhov kev tshaj tawm siab tshaj plaws filling peev.
Daim ntawv thov tiag tiag yuav tsum raug soj ntsuam raws li lub hom phiaj qhov hnyav, xav tau tus nqi ntau lawm, cov yam ntxwv ntawm cov hmoov, hom pob, sau qhov tseeb, thiab kev pub mis.
Lub tshuab ua haujlwm ze rau nws qhov kev txwv tsis pub siv yuav nyuaj rau kev tswj ntau dua li qhov loj me rau daim ntawv thov.
Piv txwv li, cov hmoov filling system npaj rau lub hnab loj yuav xav tau kev sib txawv ntawm kev siv tshuaj los ntawm ib qho system tsim rau cov ntim me me. Lub tshuab filling, hopper, qhov hnyav, thiab kev tswj lub tswv yim yuav tsum tau sib phim rau qhov kev npaj ua haujlwm.
Ntsuam xyuas cov txheej txheem ua kom tiav
Txoj kev txhim khu kev qha zoo tshaj plaws los txhim kho cov hmoov txhaws qhov tseeb yog los ntsuas cov txheej txheem ua tiav es tsis yog ib feem.
Kev ntsuam xyuas ib txwm yuav tsum xav txog:
Hmoov khoom → Pub → Hopper → Dosing mechanism → Nyhav → Control system → Discharge
Yog tias qhov kawg filling qhov hnyav tsis sib haum, qhov teeb meem tuaj yeem tshwm sim nyob qhov twg ntawm tus txheej txheem no.
Piv txwv li, hloov ib lub xov tooj ntawm tes yuav tsis daws qhov teeb meem txuas rau hauv lub hopper. Kev nce auger ceev yuav tsis daws qhov teeb meem tsis ruaj khov. Hloov lub tshuab filling yuav tsis tas yuav daws tau cov hmoov formulation uas txawv ntawm cov khoom siv.
Qhov no yog vim li cas kev xaiv tshuab thiab kev sim cov txheej txheem yuav tsum tau ua ua ke.
Yuav ua li cas DJ-PACK mus rau Powder Filling Accuracy
Rau kev lag luam hmoov ntim cov ntawv thov, DJ-PACK tsom mus rau kev sib piv cov khoom ntim rau cov yam ntxwv ntawm cov khoom thiab cov neeg siv khoom tsim khoom.
Nyob ntawm daim ntawv thov, lub tshuab ntim hmoov tuaj yeem teeb tsa nrog kev pub noj kom tsim nyog, hopper, auger dosing, hnyav, hnab ntim khoom, lossis cov cuab yeej pabcuam.
Lub hom phiaj tsis yog tsuas yog qhia lub tshuab filling nrog lub siab nominal raug daim duab. Kev siv cov hmoov filling tov yuav tsum muab cov khoom noj ruaj khov, tswj kev noj, rov ua haujlwm dua, thiab muaj peev xwm tsim tau rau cov khoom tiag.
Vim li no, cov khoom kuaj thiab cov ntaub ntawv thov muaj txiaj ntsig zoo thaum xaiv lub tshuab ua hmoov filling. Hom hmoov, lub hom phiaj sau qhov hnyav, pob hom, muaj peev xwm tsim tau, thiab qhov yuav tsum tau muaj tseeb tuaj yeem cuam tshuam rau cov khoom siv pom zoo.
Kev xav zaum kawg
Kev txhim kho hmoov txhaws qhov tseeb yuav tsum tau ntau tshaj li kev kho ib lub tshuab parameter. Cov hmoov nws tus kheej, kev pub mis, filling tshuab, lub cev hnyav, lub tshuab teeb tsa, thiab qhov chaw tsim khoom txhua qhov ua rau qhov kawg tshwm sim.
Txoj hauv kev zoo tshaj plaws yog thawj zaug txheeb xyuas qhov kev hloov pauv, tom qab ntawd txhim kho cov khoom ntws, xaiv cov txheej txheem filling tsim nyog, ntsuas qhov ntsuas qhov ntsuas, ua kom zoo dua lub tshuab tsis zoo, thiab txheeb xyuas qhov ua tau zoo raws li kev tsim khoom tiag tiag.
Rau cov tuam txhab lag luam cuam tshuam nrog qhov hnyav hnyav hnyav, cov lus nug yog yog li tsis yooj yim"Kuv yuav ua li cas thiaj ua tau lub tshuab filling kom raug?"
Ib lo lus nug zoo dua yog:
"Qhov twg ntawm cov txheej txheem ua tiav cov hmoov filling yog tsim cov variation?"
Thaum qhov chaw ntawd raug txheeb xyuas, lub tshuab thiab cov txheej txheem tuaj yeem hloov kho raws li cov khoom siv tiag tiag tsis yog qhov kev xav.
