cov ntsiab lus
Thaum lub siab ntawm lub tshuab pellet khoom noj dev siab dhau lawm (siab dua 5.5 MPa), lub tswv yim hloov kho tseem ceeb yog "txo qis extrusion tsis kam + txo cov khoom siv raw khoom," thaum tib lub sij hawm daws qhov teeb meem ntawm qhov ua haujlwm tsis zoo. Ua ntej, siv "tuag tu + orifice hloov" txoj kev hloov kho: Tom qab nres lub tshuab thiab tshem tawm lub hwj chim, disassemble lub taub hau tuag thiab ntxuav tawm cov khoom siv raw khoom (cov dej noo ntau dhau los yog qhov loj me me hauv cov ntaub ntawv nyoos yooj yim ua rau tuag lub taub hau, ua kom tawm tsis kam). Yog hais tias lub taub hau tuag yog hnav me me dhau, hloov nws nrog lub taub hau tuag nrog lub qhov ncauj loj dua. Thib ob, siv "kev txo qis qis + kub nce" txoj kev hloov kho: Txo cov khoom noj ceev los ntawm 10-15% kom txo cov khoom siv raw nkag mus, thaum tib lub sijhawm nce cua sov los ntawm 5-10℃txhawm rau txhim kho cov dej ntws ntawm cov khoom siv raw thiab txo cov khoom siv extrusion. Yog tias lub siab tseem siab dhau tom qab hloov kho, xyuas cov ntsia hlau hnav. Hnav cov npoo ntawm cov ntsia hlau tuaj yeem ua rau cov khoom xa tuaj tsis sib xws, kev sib txuam hauv cheeb tsam, thiab nce siab, yuav tsum tau hloov cov ntsia hlau.
Thaum lub siab ntawm me me qhuav aub ua tshuab ua zaub mov qis dhau (qis dua 2 MPa), lub tswv yim kev hloov kho tseem ceeb yog "nce extrusion resistance + nce raw khoom ntim nyiaj," thaum tib lub sij hawm daws qhov teeb meem. Ua ntej, "kev hloov pauv tuag + nce tus nqi noj" yog siv txoj kev hloov kho: hloov nrog tuag nrog ib qho ntawm txoj kab uas hla me me kom ua rau muaj kev tawm tsam, thiab ib txhij nce tus nqi pub los ntawm 10-15% kom nce tus nqi ntawm cov khoom siv raw ua rau lub tshuab extrusion thiab nce siab. Qhov thib ob, "txo qhov kub thiab txias + raw cov ntaub ntawv noo noo hloov" txoj kev yog siv: txo cov cua sov los ntawm 5-10℃los ua kom cov viscosity ntawm cov khoom siv raw thiab nce extrusion kuj. Yog tias cov khoom siv raw cov dej noo tsawg dhau (qis dua 12%), txau cov dej sov kom tsim nyog los kho cov dej noo mus rau 12-15%, txhim kho cov khoom ruaj khov thiab nce siab. Yog tias qhov siab tseem qis dhau tom qab hloov kho, cov khoom siv tuag yuav tsum tau kuaj xyuas. Kev hnav khaub ncaws ntau dhau (dhau ntawm tus qauv orifice txoj kab uas hla los ntawm 0.2mm) yuav ua rau muaj kev tawm tsam tsis txaus, yuav tsum tau hloov tuag. Piv txwv li, thaum ua cov khoom noj miv, yog tias tuag hnav ua rau lub siab tsuas yog 1.8MPa, hloov qhov tuag thiab nce tus nqi pub rau 38Hz yuav nce siab mus rau qhov qub ntawm 4MPa.
Thaum lub siab hloov pauv ntawm cov khoom tsim khoom noj dev loj dhau lawm, "kev noj zaub mov ruaj khov + kev sib koom ua ke ntawm qhov kub thiab txias" yuav tsum tau txais kev pom zoo: xyuas seb qhov kev pub noj puas raug thaiv, xyuas kom meej tias cov khoom siv raw nkag mus rau ntawm qhov sib xws, thiab zam kev hloov pauv sai ntawm cov khoom siv raw; stabilize cov cua sov kub nrog lub ntsuas kub kom tsis txhob muaj qhov kub thiab txias ua rau muaj kev hloov pauv ntawm cov ntaub ntawv raw, uas ua rau muaj kev hloov pauv siab. Nyob rau tib lub sijhawm, xyuas seb cov khoom siv lub hauv paus bolts puas xoob, vim cov khoom siv vibration tuaj yeem ua rau lub siab tsis ruaj khov, thiab cov bolts yuav tsum tau nruj.
