Extruder Mechanical Txoj Cai
Aug 03, 2024| Txoj cai ntawm ib qho ntsia hlau extruder
Ib leeg ntsia hlau feem ntau muab faib ua peb ntu hauv qhov ntev. Qhov ntev ntawm peb ntu yog txiav txim siab los ntawm txoj kab uas hla, lub suab thiab qhov tob ntawm cov ntsia hlau, thiab feem ntau muab faib ua ib feem peb.
Cov xov kawg ntawm cov khoom siv chaw nres nkoj hu ua seem conveying: cov khoom ntawm no yuav tsum tsis txhob yuav plasticized, tab sis yuav tsum tau preheated thiab nias. Yav dhau los, txoj kev xav extrusion qub ntseeg tias cov khoom ntawm no yog lub cev xoob. Tom qab ntawd, nws tau ua pov thawj tias kev txav ntawm cov khoom ntawm no zoo ib yam li cov khoom piston. Yog li ntawd, ntev npaum li cas txoj haujlwm conveying tiav, nws yog nws txoj haujlwm.
Qhov thib ob yog hu ua ntu compression. Lub sijhawm no, qhov ntim ntawm cov ntsia hlau zawj maj mam txo qis los ntawm qhov loj mus rau me me, thiab qhov kub yuav tsum ncav cuag qib ntawm plasticization ntawm cov khoom. Lub compression generated ntawm no yog los ntawm conveying seem peb mus rau ib qho ntawm no. Qhov no yog hu ua compression piv ntawm cov ntsia hlau - 3: 1. Qee lub tshuab kuj muaj kev hloov pauv. Cov khoom siv plasticized nkag mus rau ntu thib peb.
Ntu peb yog ntu ntsuas ntsuas. Cov khoom ntawm no tuav lub plasticizing kub. Nws tsuas yog raug thiab ntau thauj cov khoom yaj zoo li lub twj tso kua mis ntsuas los muab lub taub hau. Lub sijhawm no, qhov kub tsis tuaj yeem qis dua qhov kub ntawm plasticizing, thiab feem ntau yog siab dua me ntsis.
