Yuav ua li cas xaiv ib tug yas extruder

Thaum cov neeg siv khoom siv txhaj tshuaj molding tshuab thiab pwm, peb inevitably yuav tsum tau siv yas extruder
Kev xaiv ntawm extruder feem ntau yog hais txog cov txheej txheem hauv qab no:

Screw txoj kab uas hla yog hais txog sab nraud txoj kab uas hla ntsia hlau xov. Qhia los ntawm D, unit yog mm
Qhov sib piv ntawm qhov ntev-rau-inch ntawm cov ntsia hlau yog hais txog qhov sib piv ntawm qhov ntev ntawm cov ntsia hlau xov rau txoj kab uas hla ntawm cov ntsia hlau., qhia hauv L/D.
Qhov ceev ntawm cov ntsia hlau yog hais txog qhov siab tshaj plaws thiab qis tshaj ntawm cov kiv puag ncig thaum cov ntsia hlau ua haujlwm
Lub cev muaj zog yog hais txog lub zog ntawm lub cev muaj zog uas tsav lub hau ntswj kom tig, sawv cev los ntawm P
Lub hwj chim hluav taws xob yog hais txog lub zog hluav taws xob thaum lub thoob yog cua sov los ntawm kev ua haujlwm, unit is KW

Nyob rau hauv cov ntaub ntawv ntawm tib configuration, nws nyob ntawm qhov zoo thiab kev ua haujlwm

Nws yog qhov zoo tshaj los yuav ib tshuab los tshuaj xyuas qhov ntsuas thiab lub zog ntawm lub Hoobkas. Kuv xav koj tshuab zoo thiab khoom siv
2.Yuav ua li cas yog tias qhov kub ntawm qhov chaw nres nkoj ntawm cov yas extruder siab dhau lawm

Muaj lub tsho dej ntawm lub thoob hauv qab qhov qhib pub, ib qho inlet thiab lwm qhov hluav taws xob, feem ntau los tiv thaiv qhov kub ntawm lub thoob los ntawm siab dhau lawm, tsim ib tug choj phenomenon, thiab muaj txoj cai los txhim kho cov dej ntws mus rau ntawm lub thawv txo qis. Lub luag haujlwm yog los tiv thaiv kub siab dhau.
Yog hais tias koj yog ib tug tsis tshua muaj siab pellet, koj tsis tas yuav nce qhov kub ntawm lub hopper siab heev, yog li qhov kub ntawm qhov chaw nres nkoj tawm kuj yuav poob. Yog tias qhov xwm txheej tseem tsis zoo, nws raug pom zoo kom nruab ib lub pwm kub tswj kom ntsuas qhov kub ntawm cov ntsia hlau ntawm tus nqi tas li.

3.Vim li cas cov ntsia hlau ntawm cov yas extruder tawg?

Nws yog ib qho tsim nyog los txheeb xyuas cov kab ntawm cov kab tawg hauv kev nthuav dav. Yog tias muaj hlau ua npuas ncauj lossis hlau av nyob ze, nws yog tshwm sim los ntawm kev sib txhuam mus ntev. Saib seb puas muaj qhov chaw uas muaj kev sib txhuam tshwm sim nyob ib puag ncig. Yog cov seem huv si thiab tshiab, Nws tuaj yeem tshwm sim los ntawm kev ua tsis tiav tam sim ntawd.

4.Yuav ua li cas xam cov extrusion ntim ntawm cov yas extruder

Rau extruder, seb nws yog ib tug ntsia hlau los yog ib tug ntxaib ntsia hlau, ob lub tswv yim yuav tsum tau piav qhia thaum nws los txog rau lub peev xwm extrusion:
1. Theoretical txwv extrusion
2. Qhov tseeb extrusion ntim

Lub theoretical txwv ntawm extrusion yog xam los ntawm cov ntsia hlau geometry (cross-sectional area of ​​the internal space of the chim-cross-sectional area of ​​the screw = cross-sectional area ntawm tus khiav) thiab tom qab ntawd muab faib los ntawm cov hlau lead ntawm cov hlau lead loj hauv cov khoom noj. Nrog lub ntsiab cav ceev, tag nrho nyob rau hauv thoob ntiaj teb standard units, qhov tau m³ / h yog qhov theoretical txwv extrusion ntim ntawm qhov ceev no.

Qhov tseeb extrusion ntim tsis tas yuav suav. Feem ntau hais lus, nws yog metered pub. Lub ntim extrusion yog lub ntim ntim uas koj tau teem tseg. Yog nws tshaib plab (qhov tseeb, Nws tsis tshua muaj vim tias qhov pub mis tsis ruaj khov txaus), nws yuav tsum tau muab cov yam ntxwv ntawm cov khoom siv, xws li hmoov los yog pellets, Dab tsi yog qhov fluidity ntawm cov khoom siv, thiab cov qauv ntawm cov khoom siv pub mis Qhov loj yog cuam tshuam, tab sis feem ntau qhov tseeb extrusion ntim ntawm cov khoom noj tshaib plab yuav tsis tshaj 80% ntawm theoretical txwv extrusion ntim

Thaum tsim cov metering pub ntim, nws yog feem ntau tsim nyog yuav 60% ntawm theoretical txwv extrusion ntim, thiab tsis tas yuav kho qhov ntim pub rau hauv ib qho chaw tswj hwm ceev.

Vam tias yuav pab tau rau sawv daws, haha, Kuv thov kom koj ua tiav.
