1.Kev tshuaj xyuas qhov tsis xws luag ntawm PE yeeb nkab kub yaj welder

PE yeeb nkab kub yaj vuam tshuab yog siv nyob rau hauv lub installation ntawm ib tug yeeb nkab network project.Txoj kab uas hla ntawm cov kav dej tseem ceeb yog ntau dua 63 hli thiab phab ntsa thickness ntau dua 5 hli.Nyob rau hauv cov txheej txheem ntawm vuam xws li cov yeeb nkab ntsiab lus, qhov siab tshaj plaws dej siab ntawm cov yeeb nkab network yog nyob rau hauv 60m, thiab vuam precision yuav raug ignored.Txawm li cas los xij, hauv kev ua haujlwm zoo, vim yog thaj tsam roob.Yog tias cov dej siab xav tau los ntawm cov av siab dhau lawm thiab cov tshuab vuam tsis txaus, qee qhov tsis xws luag yuav tshwm sim, yog li nws yog qhov nyuaj rau kev txhim kho nws cov qib ua haujlwm thiab ua tau raws li nws cov kev xav tau. kev cai ua haujlwm.

1) Qhov tsis xws luag hauv vuam txoj kev.

Feem ntau, qhov tsis xws luag ntawm welded sib koom ua ke yog vim qhov sib txawv ntawm crimping geometry thiab cov qauv, uas tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua.

Ua ntej, yog hais tias muaj stains los yog txawv teb chaws teeb meem ntawm lub vuam kawg lub ntsej muag, nws yuav ua rau lub deviation ntawm lub thickness ntawm lub vuam phab ntsa ntawm ob sab.Nyob rau hauv cov ntaub ntawv ntawm cov cua sov tsis sib xws, yuav muaj asymmetry nyob ib ncig ntawm lub vuam interface, thiab qhov luaj li cas yuav ua tsis tau raws li cov kev cai, xws li notch, gap thiab lwm yam tsis xws luag.

Qhov thib ob, yog lub ntsej muag kawg ntawm lub vuam chaw nres nkoj ntub dej thaum vuam, qhov chaw nres nkoj vuam tsis yog pob tshab thiab ruaj khov;Los yog muaj dej vapor, uas yuav ua rau cov teeb meem vuam zoo thiab cov dej xau.

Thib peb, yog hais tias lub ovality ntawm welded kav tsis tau raws li cov kev cai, kev ntseeg ntawm lub pob tw pob qij txha yuav tsis tau guaranteed, thiab cov teeb meem ntawm misalignment yuav tshwm sim.

Plaub, yog hais tias lub fixture stroke deviates, los yog thaum melting, docking kub thiab siab yog tsawg thiab lub vuam lub sij hawm luv luv, qhov zoo ntawm vuam interface yuav raug txo.Yog hais tias qhov ceev ntawm lub fixture yog ceev, los yog qhov kub thiab txias yog siab, qhov siab ntawm lub vuam interface yog siab los yog dav heev, uas artificially txo cov dej ntws seem thiab txo nws cov tsim txaus.

2) Micro defect teeb meem.

Micro defects yog cov teeb meem zoo hauv kev sib txuas vuam, xws li cov kab nrib pleb, tawg, tsis zoo nkag mus thiab lwm yam.

Ua ntej, yog tias qhov zoo ntawm cov yaj kub uas siv los ntawm cov kws tsim kho kev tsim kho tsis zoo lossis muaj qhov sib txawv ntawm qhov ntws, lub pob tw zoo ntawm cov kav dej yuav raug txo.Piv txwv li, thaum qhov sib txawv ntawm qhov txaus txaus siab tshaj li ntawm 0.6g / 10min, qhov tsis zoo ntawm vuam interface yuav tshwm sim.Yog hais tias lub melting kub yog tsawg los yog lub vuam ib puag ncig tsis zoo, kuj yuav muaj vuam interface tawg thiab tawg.

Qhov thib ob, hauv kev tsim kho tiag tiag, lub ntsej muag kawg ntawm cov raj xa dej tsis sib npaug, lossis lub ntsej muag kawg tsis tau welded los ntawm kev siv lub tshuab cua sov, uas ua rau cov vuam tsis zoo permeability.

3) Microscopic defects.

Nyob rau hauv qhov tseeb welding ua hauj lwm, vim lub kub kub los yog lub sij hawm ntev cua sov, cov yeeb nkab yuav oxidized thiab puas.Hauv qhov xwm txheej hnyav, carbonization yuav tshwm sim, tom qab ntawd los ntawm cov khoom siv deterioration.Rau vuam tsis xws luag, muaj ntau yam teeb meem sib cuam tshuam.Yog tias cov neeg ua haujlwm thiab cov kws tshaj lij tsis muaj peev xwm thiab lub luag haujlwm

Txhua qhov kev nkag siab ntawm lub luag haujlwm, tsis ua haujlwm cuam tshuam raws li cov khoom siv thiab cov kev xav tau ntawm vuam yuav maj mam txo qhov zoo ntawm vuam engineering.
