Raws li cov khoom siv tseem ceeb hauv cov plastics ua kev lag luam, yas ultrasonic machine 'kev ua haujlwm cov txheej txheem ncaj qha tsawg dua, khoom zoo, thiab cov khoom siv tau ua haujlwm. Mastering kev tshawb fawb ua haujlwm thiab cov tswv yim txij nkawm yog qhov tseem ceeb los ua kom tiav ntau lawm.
1. Pib thiab parameter teeb txheej txheem
Ua ntej pib lub tshuab yas yas, kom huv si xyuas cov roj hauv hydraulic, pwm teeb tsa, thiab cua sov. Thaum lub sijhawm pib ua haujlwm, nws raug nquahu kom sim lub tshuab ntawm qis ceev thiab tsis muaj thauj khoom siv, maj mam hloov kho rau cov khoom ntsuas. Kev tswj qhov kub thiab txias yog qhov tseem ceeb heev. Lub qhov kub yaj ntawm cov ntaub ntawv yas sib txawv (xws li PVC thiab PE) sib txawv ntau, xav tau cov khoom muaj tseeb raws li cov khoom siv. Piv txwv li, pvc profile ua feem ntau yuav tsum tau lub cav kub ntawm 160 - 190 degree. Kev kub dhau heev tau yooj yim ua rau kev txiav txim siab, thaum muaj kev kub ntau dhau tuaj yeem cuam tshuam fluidity. Tsis tas li ntawd, kev txhaj tshuaj nyem siab thiab nrawm yuav tsum tau ua raws li cov qauv pwm kom tsis txhob muaj eeb kom tsis txhob muaj qhov tsis taus lossis luv luv txiav tsis xws luag los ntawm parameter tsis xwm yeem.
2. Cov tswv yim txhim kho thaum lub sijhawm ntau lawm
Lub sij hawm ua lag luam nrom, cov khoom siv tau yooj yim xeev thiab puab cov kev sib tw kub yuav tsum tau saib xyuas lub sijhawm tiag tiag. Yog tias qhov sib txawv ntawm cov kev sib txawv lossis qhov sib txawv sib txawv tau pom nyob rau hauv daim ntawv qhia, ua ntej kuaj xyuas cov pob zeb txias rau kev thaiv lossis kho cov dej txias ntws. Rau cov khoom siv nquag tiv thaiv, nws raug pom zoo kom tsis tu ncua ntxuav cov kis ntawm ntsia hlau thiab chim thiab siv cov qauv cua sov station kom txhim kho cov khoom siv. Operators should be familiar with the equipment's pressure-flow curve and fine-tune backpressure parameters to optimize plasticizing quality and reduce energy consumption.
3. Txij Nkawm thiab Kev daws teeb meem
Thaum niaj hnub saib xyuas, tsom rau kev kuaj xyuas cov kev nyiam huv ntawm cov roj hydraulic thiab ntim cov hnav. Nws raug nquahu kom hloov lub lim keeb thiab rov ua cov roj nplua nyeem txhua txhua 500 teev. Ua ntej ntev - lub sij hawm downtime, yuav tsum tau huv si kom tiv thaiv cov roj hmab uas muaj carbon monoxide los tiv thaiv cov khoom siv roj carbon monoxeting. Feem ntau cov kev ua txhaum xws li tsis muaj suab nrov lossis siab hloov pauv yog feem ntau tshwm sim los ntawm cov khoom siv hluav taws xob lossis kev tswj hluav taws xob tsis zoo, xav tau kev tshawb nrhiav sai thiab kev tshawb nrhiav. Nquag calibring ntsuas kub thiab siab gauges kom ntseeg tau cov ntaub ntawv raug thiab txuas ntxiv cov cuab yeej siv sijhawm.
Mastering cov kev qhia no yuav tsis tsuas yog txhim kho cov khoom tsim tau yooj yim ntawm cov khoom siv yas, tab sis kuj txo cov nqi siv zog thiab cov nqi kho. Cov neeg ua haujlwm yuav tsum muaj kev ua haujlwm sib txuas nrog cov kev ua haujlwm tiag tiag kom haum cov tswv yim no kom haum siv tau thiab ruaj khov kev lag luam.
