Thaum lub sijhawm ua haujlwm ntev, cov polyethylene melted thiab butane -foaming residue tuaj yeem carbonize hauv lub taub hau tuag ntawm koj cov khoom. Ib lo lus nug ntau los ntawm cov neeg ua haujlwm yog: ua li cas koj ntxuav lub taub hau tuag ntawm aPE ua npuas ncauj tshuabkom raug? Kev tu thiab kho kom raug ntawm lub taub hau tuag ntawm lub tshuab pe ua npuas ncauj yog qhov tseem ceeb los tiv thaiv cov xim dub, tsis sib xws mesh tsim, thiab ua tiav cov blockages. Kev siv cov cuab yeej tsis raug lossis hla cov kauj ruam tuaj yeem ua rau puas tsuaj mus tas li rau qhov tseeb -machined flow channels. Hauv qab no yog cov txheej txheem txheej txheem los ntxuav lub taub hau tuag ntawm pe ua npuas ncauj tshuab.
1. Muaj kev nyab xeeb kaw thiab disassembly
Tom qab nres qhov extrusion, koom nrog LOTO (Lockout-Tagout) txhawm rau tiv thaiv kev pib ua yuam kev. Cia lub taub hau tuag kom txias rau qhov ntsuas kub zoo (kwv yees li 60-80 degree) - sov txaus uas cov seem PE yog mos tab sis tsis kub txaus los hlawv. Loosen lub flange bolts tusyees nyob rau hauv ib tug ntoo khaub lig qauv thiab tshem tawm cov tuag mandrel, txheej tuag nplhaib, thiab tej breaker daim hlau. Duab los yog daim ntawv lo qhov chaw thaum lub sij hawm disassembly los xyuas kom meej reassembly ntawm koj pe foam net tshuab.
2. Tshem tawm cov khoom seem
Siv atooj liab scraper, tooj dag spatula, los yog hardwood stick - Tsis txhob siv cov cuab yeej hlau lossis cov ntsia hlau ntsia hlau - kom maj mam nqa cov PE residue los ntawm cov ntws ntws thiab daim di ncauj tuag. Hlau tuaj yeem khawb qhov polished nto, tsim micro-grooves uas yuav ntxiab cov khoom thiab ua rau cov pa roj carbon ntau ntxiv. Rau cov nplua radial slits uas tsim cov net strands ntawm pe ua npuas ncauj net tshuab, siv lub mos tooj dag los yog compressed cua (tsis tshua muaj siab) kom tshem tawm cov teeb meem.
3. Kev cuam tshuam nrog Carbonized (Kub) tso nyiaj
Yog tias cov khoom siv hluav taws xob tseem tshuav, koj tuaj yeem rov ua kom luv luv cov khoom seem tuag nyob rau hauv qhov cub tshwj xeeb kom siab tshaj qhov melting point ntawm LDPE (~ 130-150 degree) thiab so cov residue softened. Xwb, tsau cov khoom hauv cov khoom lag luam polymer-purging compound lossis ib qho kev pom zoo tuag- ntxuav muab tshuaj txhuam. Rau cov tawv nqaij tawv, maj mam txhuam nrog 600-800 grit uas tsis yog- cov ntaub qhwv abrasive - zam cov ntawv xuab zeb hnyav uas hloov cov duab geometry tuag.
4. Kev tshuaj xyuas, so, thiab rov ua dua
So txhua qhov chaw nrog lint -dawb daim ntaub dampened nrog isopropyl cawv los yog ib tug me me degreaser. Tshawb xyuas daim di ncauj tuag thiab sealing ntsej muag rau khawb, corrosion, los yog deformation. Siv cov yeeb yaj kiab nyias nyias ntawm siab - kub los tiv thaiv - ntes roj rau bolt threads ua ntej rov sib dhos. Torque lub flange bolts tusyees ntawm pe npuas net tshuab chaw tsim tshuaj paus cov specification kom tsis txhob tuag distortion los yog yaj to. Preheat qhov tuag maj mam ua ntej restarting ntau lawm.
5. Cov lus qhia tiv thaiv
Ua lub teeb sab nraud so-down ntawm lub ntsej muag tuag ntawm txhua qhov kev hloov pauv. Teem caij ib tug tag nrho tuag disassembly thiab sib sib zog nqus ntxuav txhua txhua 3-6 lub hlis nyob ntawm lub sij hawm khiav. Tsis txhob nyob ntev ntev ntawm qhov kub thiab txias yam tsis muaj purging, vim qhov no ua rau cov pa roj carbonization hauv lub taub hau tuag ntawm koj lub tshuab ua npuas ncauj.
Hauv cov ntsiab lus, kev tu kom zoo ntawm pe ua npuas ncauj tshuab tuag lub taub hau yuav tsum tsis yog - cov cuab yeej ferrous, ua tib zoo tswj thermal, thiab cov txheej txheem reassembly. Ua raws li cov txheej txheem no txuas ntxiv lub neej tuag, tswj cov mesh zoo, thiab txo qis lub sijhawm tsis tau npaj tseg.
