I. Hnav Teeb meem nrog lub hau thiab lub thoob
Qhov no yog qhov teeb meem tseem ceeb tshaj plaws nrog kev siv extruders thiab ib qho nrog cov nqi kho siab tshaj plaws.
Cov tsos mob thiab ua rau: Thaum lub sijhawm ua haujlwm, cov ntsia hlau thiab lub thoob tau hnav tsis tu ncua los ntawm cov khoom ntim hauv cov khoom, xws li calcium carbonate thiab iav fiber. Raws li kev hnav zoo zuj zus, qhov kev tshem tawm ntawm cov ntsia hlau thiab lub thoob yuav nce ntxiv, ua rau cov yas tsis zoo, cov khoom siv extrusion tsis ruaj khov, thiab txo qis ntau lawm. Hauv qhov xwm txheej hnyav, "slippage" tuaj yeem tshwm sim- qhov twg cov khoom tsis raug xa mus rau pem hauv ntej hauv seem pub.
Cov Ntsiab Lus Tshawb Fawb: Thaum lub sijhawm sim khiav, saib seb qhov tam sim no tseem nyob ruaj khov; tshawb xyuas qhov saum npoo ntawm cov ntawv tsim rau cov pob tsis muaj crystalline; Yog tias tsim nyog, siv lub ntsuas ntsuas qhov ntsuas siab lossis ua qhov "tso zis sib piv ntsuas" (tseem ntsuas cov zis ib lub sijhawm ntawm tib lub sijhawm sib hloov thiab muab piv rau tus qauv tus nqi rau lub tshuab tshiab). Yog tias hnav ntau dua 0.5% ntawm cov ntsia hlau txoj kab uas hla, kev kho lossis hloov pauv feem ntau yuav tsum tau, uas sawv cev rau tus nqi tseem ceeb.
II. Kev laus thiab tsis ua haujlwm ntawm cov cua sov thiab cua txias
Cov Cuab Yeej Cuab Yeej: Hauv cov cuab yeej siv, cov khoom siv cua sov feem ntau pom muaj teeb meem xws li qhov chaw tsis muaj cua sov, cua sov tsis sib xws, lossis txo cov rwb thaiv tsev (tsawg hluav taws xob). Cov no tuaj yeem raug tshuaj xyuas los ntawm kev siv lub koob yees duab thermal imaging lossis los ntawm kev ua lub zog segmented - ntawm kev sim. Kev laus cua sov ntsiab lus tsis tsuas yog cuam tshuam rau qhov kub thiab txias qhov tseeb tab sis kuj ua rau muaj kev hloov pauv hauv daim ntawv tuab thiab qhov tsis sib xws ntawm qhov gloss.
Cov Cuab Yeej Cuab Yeej Cuab Yeej: Cov cua txias (cua- txias lossis dej- txias) hauv extruders feem ntau tsis saib xyuas. Cov teeb meem tshwm sim muaj xws li txhaws qhov cua txias, daig solenoid li qub, thiab kiv cua tsis txaus. Yog tias lub tshuab ua kom txias tsis ua haujlwm, qhov kub ntau dhau tuaj yeem ua rau cov khoom tawg, ua rau cov kab dub lossis cov khoom siv hluav taws xob, uas cuam tshuam ncaj qha rau daim ntawv zoo.
III. Ncua kev puas tsuaj nyob rau hauv lub Gearbox thiab Transmission System
Gearbox: Qhov no yog "lub plawv" ntawm cov khoom siv. Ua tib zoo mloog cov suab nrov txawv txav (xws li lub suab txawv txawv los ntawm cov iav meshing lossis kev sib tsoo qhuav los ntawm cov kabmob); xyuas lub gearbox roj ntsaws ruaj ruaj rau cov xau; soj ntsuam cov xim ntawm cov roj lubricating- yog tias nws zoo li mis nyuj dawb, qhov no qhia tias muaj dej paug, thiab yog tias nws muaj cov khoom siv hlau, nws qhia tias muaj kev hnav hnyav heev. Yog tias cov hniav txhuam hniav tawg lossis cov kabmob tsis ua haujlwm, cov nqi kho yuav siab thiab cov txheej txheem kho yuav siv sijhawm ntev.
Cov couplings: Tom qab ua haujlwm ntev, lub hnub qub - zoo li cov elastomeric couplings lossis universal couplings ua rau qaug zog thiab tawg, ua rau kev sib kis kev vibration thiab txo qhov raug, uas ntxiv nrawm rau hnav ntawm cov ntsia hlau thiab chim.
IV. Kev puas tsuaj thiab deformation ntawm Pwm (Tuag) Runners
Lub precision ntawm cov ntawv hlau pwm ncaj qha txiav txim siab qhov ntev ntawm cov nplooj ntawv.
Khiav Kev Puas Tsuaj: Kev tuav tsis raug thaum lub sijhawm teeb tsa lossis tshem tawm daim di ncauj tuag tuaj yeem yooj yim khawb qhov chaw ntawm cov neeg khiav dej num. Kev siv cov khoom siv ntev ntev uas muaj cov khoom siv corrosive tuaj yeem ua rau xeb lossis pitting ntawm phab ntsa sab hauv ntawm cov neeg khiav dej num. Cov teeb meem no tuaj yeem ua rau muaj qhov tsaus nti, cov cim ntws, lossis cov tuab tsis sib xws ntawm daim ntawv.
Die Dip Deformation: Kev hloov kho tsis tu ncua rau qhov qhib qhov ncauj tuag yuav ua rau lub zos deformation ntawm daim di ncauj tuag los yog stripped bolts. Thaum yuav khoom tuag, nws yog qhov zoo tshaj plaws los thov kev sim ntau lawm khiav ntawm lub tshuab thiab ntsuas cov ntawv transverse thickness kam rau ua. Yog hais tias qhov sib txawv ntau tshaj 5% -10%, nws qhia tau hais tias qhov tuag yog nyob rau hauv tsis zoo.
V. Cov Teeb Meem Muaj Peev Xwm nrog Cov Hluav Taws Xob Tswj Hluav Taws Xob thiab Cov Tsav Tsheb Tsis Txaus Siab (VFDs)
Cov tshuab hluav taws xob ntawm cov cuab yeej siv feem ntau muaj hnub nyoog hnyav thiab tej zaum yuav raug "them ua ke" los ntawm ntau qhov chaw.
Variable Frequency Drives (VFDs): Cov khoom siv hluav taws xob sab hauv hauv VFDs qub yog hnub nyoog, uas tuaj yeem ua rau cov khoom tsis ruaj khov, tshaj lub tswb nrov, lossis nquag tawm mus. Thaum lub sij hawm sim, khiav cov cuab yeej ntawm qhov sib txawv ntawm qhov ceev kom pom seb qhov ceev tseem nyob ruaj khov thiab xyuas seb cov lus yuam kev txawv txav.
Thermostats thiab Sensors: Kev poob qis hauv cov thermocouples lossis cov ntsuas kub tuaj yeem ua rau qhov sib txawv ntawm ntau tshaj kaum degrees ntawm qhov kub thiab txias. Nws raug nquahu kom siv tus tiv tauj - hom ntsuas kub ntsuas qhov ntsuas qhov ntsuas lub tog raj kheej thiab muab piv nrog lub ntsuas ntsuas kev nyeem ntawv.
Kev Tiv Thaiv Kab Mob: Saib xyuas cov kab hluav taws xob kom pom cov cim ntawm kev laus lossis tawg tawg, thiab xyuas lub vaj huam sib luag hluav taws xob kom pom qhov kub hnyiab, vim tias cov no yog qhov muaj feem xyuam rau kev nyab xeeb.
VI. Cov teeb meem nthuav dav pom hauv cov khoom zoo
Yog tias muaj kev tso cai, nws yog qhov zoo tshaj los khiav cov cuab yeej tsis tu ncua rau 2-4 teev thiab ua tau cov nplooj ntawv; qhov no yog txoj hauv kev ncaj qha tshaj plaws los kuaj cov khoom siv. Ua tib zoo saib xyuas cov teeb meem hauv qab no:
Cov tuab tuab tsis sib xws: Qhov no yuav tshwm sim los ntawm kev hloov pauv hauv kev tuag ceev, ntsia hlau nrawm, lossis tsis ruaj khov nro.
Cov kab dub lossis cov khoom siv hluav taws kub nyhiab ntawm qhov chaw: Qhov no feem ntau tshwm sim los ntawm cov khoom siv degradation vim qhov chaw tuag hauv cov ntsia hlau, chim, lossis tuag, lossis los ntawm kev tawm ntawm - ntawm - tswj cov cua sov.
Qhov dav dav shrinkage lossis hnyav warping: Qhov no yuav suav nrog kev teeb tsa tsis raug ntawm kev tsim tuag, lub tank dej txias, lossis lub tshuab traction siab. Cov teeb meem no tsis tshua muaj kev daws teeb meem los ntawm kev hais txog ib leeg ib leeg.
