Vim muaj kev siv dav hauv cov khoom siv yas hauv kev lag luam thiab kev ua liaj ua teb, cov tshuab yas tau dhau los ua kev lag luam tseem ceeb hauv kev lag luam machinery. Tom qab siv lub tshuab hloov zaus los kho qhov nrawm, cov tshuab yas tuaj yeem txuag hluav taws xob (txog 20-60}% tuaj yeem txuag tau), txo qhov cuam tshuam ntawm daim phiaj hluav taws xob, ua tiav kev siv hluav taws xob ntsuab, thiab txhim kho cov khoom zoo thiab cov khoom siv.
Muaj ntau hom yas tshuab, suav nrog calenders, zaj duab xis tshuab tshuab, sealing thiab txiav tshuab, txhaj tshuaj molding tshuab, yas hlau trough tshuab, yas buckle tshuab, yas yeeb extruders, zaj duab xis extruders, molding tshuab, yas txheej thiab compounding tshuab, hlau tshuab kos duab, tshuab kneading, tshuab tshuab yas, tshuab auxiliary machinery (cua blowers, kua xa, nplawm, sib tov), thiab lwm yam. Ntawm cov khoom siv yas hais saum toj no, tshwj tsis yog rau plaub-yob calender, uas yuav tsum tau muaj kev sib koom ua haujlwm siab, lwm tus yog cov neeg siv khoom siv ntau heev. Cov kev cai rau lub traction system yog qhov tseem ceeb tib yam.
1. Nws tuaj yeem kho qhov nrawm nrawm hauv qee qhov ntau los pab txhawb kev noj cov khoom sib txawv.
2. Ua haujlwm yooj yim pib thiab nres. Yas machinery feem ntau yog ib qho torque load tas li. Thaum pib ntawm qhov qis qis, nws kuj yuav tsum muaj qee qhov torque kom lub tshuab pib ua haujlwm zoo.
3. Kev ua haujlwm ruaj khov thiab txhim khu kev qha. Txhawm rau kom ntseeg tau tias cov khoom yas zoo, kev ua haujlwm ntawm traction system yuav tsum ruaj khov heev.
Siv qhov sib txawv zaus tswj qhov system ntawm zaj duab xis tshuab tshuab ua piv txwv los ua cov lus qhia luv luv:
Qhov sib txawv zaus ceev tswj traction system ntawm zaj duab xis tshuab tshuab muaj ob ntu: ib qho yog qhov sib txawv ntawm qhov ceev ceev ntawm lub tshuab extrusion lub ntsiab, thiab lwm qhov yog qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm lub tshuab traction. Lawv tswj tau yooj yim heev. Qhov ceev ntawm lub cev muaj zog tuaj yeem hloov kho los ntawm cov keyboard ntawm lub vaj huam sib luag lossis lwm qhov muab potentiometer. Kev ua haujlwm presets ntawm zaus converter feem ntau yog cov hauv qab no:
1. Kev teeb tsa zaus: Cov keyboard lossis lwm lub potentiometer tuaj yeem siv rau kev teeb tsa.
2. Sab sauv thiab qis qis zaus: Cov zaus txwv sab saud yog feem ntau me ntsis siab dua qhov ntsuas zaus, thiab qis qis zaus feem ntau yog teem rau 3hz.
3. Inching zaus: Feem ntau, nws tuaj yeem raug preset rau 8hz.
4. Ceev thiab ceev lub sij hawm: Txij li cov tshuab yas tsis tas yuav pib thiab nres ntau zaus, tsis muaj qhov yuav tsum tau ua kom nrawm nrawm thiab nrawm. Lub hauv paus ntsiab lus tsis yog kom tshaj qhov ntsuas tam sim no, tab sis rau kev sib khi thiab txiav cov cav tov, nws yuav tsum tau preset kom luv li sai tau.
5. Torque them nyiaj: Txij li cov tshuab yas tsis muaj qhov yuav tsum tau ua rau lub hardness thiab dynamic teb ntawm txhua yam yam ntxwv, v / f tswj hom yuav siv tau.
6. Presetting ntawm DC braking muaj nuj nqi: Ordinary yas machinery tsis tas yuav preset DC braking muaj nuj nqi, tab sis rau sealing thiab txiav tshuab, thiaj li yuav txo tau lub sij hawm deceleration, presetting DC braking yog tsim nyog.
