Cov teeb meem suab nrov hauv cov tshuab siv yeeb nkab extrusion feem ntau yog qhov nyuaj dua li cov khoom siv tshiab, ua cov cim tseem ceeb rau kev ntsuas lub tshuab qhov xwm txheej thiab cov nqi seem. Lub suab nrov feem ntau tshwm sim los ntawm ntau qhov chaw, suav nrog kev tsav tsheb (lub cev muaj zog, gearbox), kev sib cuam tshuam ntawm cov ntsia hlau thiab lub thoob, nrog rau kev teeb tsa thiab hnav.
I. Cov teeb meem kev sib kis
Cov kab ke sib kis ua haujlwm ua lub zog tseem ceeb ntawm extruder, nrog rau nws cov xwm txheej ncaj qha cuam tshuam rau kev ua haujlwm ruaj khov thiab suab nrov.
1. Lub cev muaj zog: lub suab nrov ntawm lub cev muaj zog tuaj yeem tshwm sim los ntawm kev hnav hnyav lossis qhov tsis tshua muaj siab ntawm rotor bearings, deformation ntawm rotor ncej, kev txhim kho txhuam tsis zoo, lossis kiv cua cov hniav scraping tiv thaiv kev ruaj ntseg. Rau cov cuab yeej siv, lub cev muaj zog hnav yog qhov nrov nrov.
2. Gear Reducer: Qhov no yog ib qho ntawm cov suab nrov nrov. Hauv kev siv cov khoom siv, kev ua haujlwm ntev feem ntau ua rau cov iav sab hauv, txo qhov tseeb, thiab qhov ua yuam kev tseem ceeb. Tsis tas li ntawd, kev puas tsuaj, lubrication tsis txaus, lossis cov roj nplua nyeem tsis txaus tuaj yeem ua rau muaj suab nrov txawv txav ntawm lub reducer. Yog hais tias lub gearbox tau kho qhov loj, kev sib dhos tsis zoo, cov iav tsis zoo, lossis sib xyaw cov iav tshiab thiab qub kuj tuaj yeem tsim lub suab nrov "clanging".
3. Siv Tsav: Rau txoj siv-tsav extruders, xoob V- siv lub rubeys, tshem tawm ntau dhau, lossis kev teeb tsa tsis raug ntawm cov tsav tsheb / tsav tsheb rub tawm ua rau V- txoj siv sia txav tawm ntawm lub dav hlau yuav ua rau muaj suab nrov.
II. Screw-Barrel Fit
Cov ntsia hlau thiab lub thoob yog cov khoom tseem ceeb ntawm extruder. Lawv haum ncaj qha cuam tshuam rau kev ruaj ntseg extrusion, thiab txhua yam teeb meem yuav ua rau pom kev sib txhuam suab nrov.
1. Concentricity thiab Perpendicularity Deviations: Thaum cov ntsia hlau tig nyob rau hauv lub thoob, tsis zoo concentricity ntawm ob lub Cheebtsam los yog ib tug tseem ceeb deviations nyob rau hauv lub perpendicularity ntawm lub thoob kawg lub ntsej muag thiab lub connecting flange yuav ua rau scraping ntawm cov ntsia hlau thiab lub thoob sab hauv phab ntsa. Qhov no ua rau lub suab nrov "squeaking" lossis "chirping".
2. Screw deformation: Siv cov cuab yeej siv nrog keeb kwm ntawm kev ua haujlwm tsis raug lossis "ntsuas ntsia hlau" (qhov twg cov khoom siv xauv cov ntsia hlau) tuaj yeem raug khoov deformation. Kev sib txawv ntau dhau ntawm cov ntsia hlau qhov axial ncaj tuaj yeem ua rau lub suab nrov thaum tig vim lub thoob khib nyiab.
3. Kev sib dhos ntau dhau: Kev tshem tawm ntau dhau ntawm cov ntsia hlau thiab nws txoj kev txhawb nqa tsav ua rau tsis zoo ntawm ob lub tog raj kheej thaum lub sijhawm sib hloov, uas ua rau muaj kev cuam tshuam tsis tu ncua lossis kev sib txhuam suab.
III. Txheej txheem thiab kev ua haujlwm Factors
Qee lub sij hawm lub suab nrov tsis yog los ntawm cov neeg kho tshuab hnav, tab sis muaj feem xyuam rau kev ua haujlwm thiab cov khoom siv.
1. Kev ntsuas kub tsis zoo: Yog tias lub thoob ntsuas kub tau qis dhau lawm, cov khoom yas pellets yuav tsis soften txaus, ua rau muaj kev sib txhuam ntau dhau ntawm cov ntsia hlau thiab lub thoob phab ntsa thiab ua suab nrov.
2. Cov khoom txawv teb chaws hauv Cov Khoom Siv: Yog tias cov khoom txawv teb chaws nyuaj lossis cov hlau tsis huv muaj nyob rau hauv cov khoom siv raw, lawv tuaj yeem tsim lub suab txawv txav thaum ntsia hlau compression thiab shearing, thiab tej zaum yuav ua rau cov ntsia hlau thiab chim.
Rau siv cov yeeb nkab extrusion tshuab, cov teeb meem suab nrov feem ntau tshwm sim los ntawm kev sib xyaw ua ke ntawm kev siv tshuab, kev sib dhos precision, thiab kev ua haujlwm. Thaum muas lossis tshuaj xyuas cov cuab yeej siv, nws raug nquahu kom them nyiaj tshwj xeeb rau kev ua haujlwm lub suab ntawm lub gearbox, qhov ua tiav ntawm qhov chaw thiab qhov ncaj ntawm cov ntsia hlau, thiab cov xwm txheej ntawm cov kabmob hauv txhua qhov sib kis. Ua ib qho kev sim khiav ntawm qhov sib txawv ntawm qhov sib txawv thiab nyob rau hauv qhov sib txawv ntawm cov loads yuav pab tau kom muaj kev ntsuam xyuas ntau dua ntawm cov khoom siv qhov tseeb.
