Thaum lub sij hawm tsim cov txheej txheem ntawm PE yeeb nkab fittings, vim muaj kev cuam tshuam ntawm ib puag ncig, tej yam tsis xws luag yuav raug tsim nyob rau saum npoo ntawm cov yeeb nkab, xws li ntxhib nto los yog zawj defects.
Yog tias qhov chaw ntawm cov khoom ntawm PE yeeb nkab haum cov chaw tsim khoom yog qhov ntxhib, nws yuav yog vim qhov kub ntawm lub taub hau ntawm lub cav tseem ceeb yog siab dhau lossis qis dhau, ua rau lub ntsej muag ntxhib.Lub hauv paus pwm kub yog qhov tsawg, thiab lub cev kub yog qhov tsawg heev, uas yog ib qho yooj yim ua rau lub puab nto yuav ntxhib.Qhov txias txias yog siab dhau lawm thiab qhov saum npoo yog ntxhib.Nyob rau hauv cov ntaub ntawv no, PE yeeb nkab haum chaw tsim tshuaj paus yuav tsum tau xyuas cov dej, xyuas seb puas muaj blockage thiab tsis txaus dej siab, xyuas seb lub cua sov nplhaib puas puas, xyuas cov kev ua tau zoo ntawm cov khoom raw, sab laj tus neeg muag khoom raw khoom, ntxuav cov pwm kub. core, thiab qhib lub pwm yog tias qhov kub thiab txias siab tshaj qhov pwm seem.Core kub hloov cuab yeej los xyuas thiab ntxuav cov pwm rau impurities.
Yog tias muaj qhov zawj hauv cov yeeb nkab, PE yeeb nkab haum cov chaw tsim khoom yuav tsum xyuas thiab kho qhov hluav taws xob ntawm cov ntaub thaiv dej ntawm lub casing, sib npaug lub siab, kho lub kaum sab xis ntawm lub nozzle kom cov yeeb nkab txias sib npaug, thiab xyuas seb puas muaj khib nyiab los yog burrs nyob rau hauv lub casing, txiav tshuab thiab lwm yam khoom.
Kev kho cov txheej txheem ntawm PE yeeb nkab fittings: Thaum qhov puas ntawm cov phab ntsa sab nrauv ntawm PE yeeb nkab yog nyob rau hauv 0.1m ntawm cov yeeb nkab phab ntsa tawg los yog lub qhov tawg, siv lub scraper kom tshem tawm cov yeeb nkab phab ntsa tawg lossis qhov tawg.Siv cyclic ketone los ntxuav qhov chaw nyob ib puag ncig hauv 0.05m, thiab txhuam nrog cov kua nplaum yas nrog cov dej tsis zoo.Tom qab ntawd, muab lub phaj arc-shaped nrog ob zaug ntawm qhov chaw puas los ntawm qhov sib txuas ntawm tib cov yeeb nkab, siv velcro muab tshuaj txhuam rau ntawm phab ntsa sab hauv ntawm qhov puas, thiab khi nrog cov hlau lead.Yog hais tias muaj cov hlua txuas ntxiv rau ntawm phab ntsa ntawm cov yeeb nkab, tshem tawm cov hlua txuas ntxiv hauv 0.05m nyob ib ncig ntawm qhov chaw puas, khawb tawm cov kab uas tsis muaj cov hlua khi, thiab siv tib txoj kev raws li saum toj no los kho.
Thaum muaj cov kab nrib pleb hauv zos lossis me me los yog qhov nyob ntawm phab ntsa sab nrauv ntawm PE yeeb nkab li ntawm 0.02m, cov dej hauv cov yeeb nkab tuaj yeem ntws tawm ua ntej, qhov puas tuaj yeem ntxuav nrog paj rwb xov, thiab tom qab ntawd lub hauv paus nto yog txhuam nrog cyclic. ketone, uas muaj cov dej tsis zoo.Lub rooj tsavxwm nrog cov duab zoo sib xws thiab qhov loj me yog muab los ntawm qhov sib txuas ntawm cov kav dej tsis siv, sib txuas, qhwv thiab kho nrog geotextile, thiab cov av tuaj yeem rov qab los tom qab 24 teev ntawm kev kho.
