Kev txhim kho HDPE (High-Density Polyethylene) yeeb nkab fittings yuav tsum tau ua tib zoo npaj thiab ua tib zoo saib kom meej. Ntawm no yog ib tug step-by-step qhia los pab koj nrog cov txheej txheem installation:
1. Sau cov khoom tsim nyog
Koj yuav xav tau cov khoom hauv qab no los nruab HDPE yeeb nkab fittings:
- HDPE kav thiab fittings
- Cov yeeb nkab clamps
- Fusion tshuab (lub taub qab fusion lossis electrofusion)
- Cov cuab yeej siv yeeb nkab
- Cov ntaub ntawv ntxuav (xws li cov ntaub so dej cawv)
- Cov cuab yeej cim (marker lossis chalk)
2. Npaj thaj chaw ua haujlwm
Xyuas kom meej tias thaj chaw ua haujlwm yog huv, zoo-ventilated, thiab tsis muaj cov khib nyiab. Xyuas kom koj muaj chaw txaus los ua haujlwm yooj yim.
3. Ntsuas thiab kos cov yeeb nkab
Ntsuas qhov ntev ntawm cov yeeb nkab thiab kos nws raws li siv lub cim lossis chalk. Nco ntsoov tso qee qhov chaw kom haum rau kev ntxig.
4. Txiav cov yeeb nkab
Siv cov yeeb nkab txiav cov cuab yeej tsim nyog (xws li cov yeeb nkab cutter lossis pom) los txiav cov yeeb nkab HDPE raws li lub cim ntev. Xyuas kom tseeb tias qhov txiav yog huv si thiab square.
5. Ntxuav cov yeeb nkab kawg
Ntxuav qhov kawg ntawm cov yeeb nkab uas siv cov tshuaj cawv los yog cov tshuaj ntxuav kom haum. Cov kauj ruam no yog qhov tseem ceeb kom tshem tawm cov av, roj, lossis cov kab mob uas tuaj yeem cuam tshuam cov txheej txheem fusion.
6. Npaj lub tshuab fusion
Yog tias koj siv lub tshuab taub qab fusion, ua raws li cov chaw tsim khoom cov lus qhia los teeb lub tshuab. Xyuas kom meej tias lub phaj cua sov yog huv si thiab nyob rau ntawm qhov tsim nyog kub rau cov yeeb nkab loj thiab haum hom.
7. Cua sov cov yeeb nkab kawg
Ntxig cov yeeb nkab xaus rau hauv lub tshuab fusion clamps, kom ntseeg tau tias lawv tau ua kom raug. Siv cov cua sov rau cov yeeb nkab kawg uas siv lub tshuab fusion cua sov phaj. Lub sijhawm cua sov yuav nyob ntawm qhov loj ntawm cov yeeb nkab thiab cov chaw tsim khoom cov lus qhia.
8. Koom nrog cov yeeb nkab thiab haum
Thaum cov yeeb nkab xaus mus txog qhov tseeb fusion kub, tshem tawm ntawm lub tshuab fusion thiab tam sim ntawd koom nrog HDPE haum. Xyuas kom muaj kev sib raug zoo thiab siv lub siab maj mam thawb qhov haum rau hauv cov yeeb nkab kom txog thaum nws ncav cuag qhov tob qhov tob ntawm qhov predetermined.
9. Cia lub fusion kom txias
Tom qab koom nrog cov yeeb nkab thiab haum, cia lub fusion kom txias raws li cov neeg tsim khoom cov lus qhia. Zam kom tsis txhob txav mus los lossis cuam tshuam thaum lub caij txias no.
10. Tshawb xyuas qhov sib koom ua ke
Thaum lub fusion tau txias lawm, pom kev tshawb xyuas qhov sib koom ua ke kom paub tseeb tias nws tsim tau zoo thiab tsis muaj qhov tsis xws luag. Saib rau tej qhov khoob, qhov tsis sib xws, lossis cov cim qhia txog kev xau. Yog tias koj pom muaj teeb meem, nrog rau cov chaw tsim khoom cov lus qhia lossis nrhiav kev pab cuam.
11. Rov ua cov txheej txheem
Yog tias koj muaj cov fittings ntxiv rau nruab, rov ua cov kauj ruam 4 txog 10 rau txhua qhov haum.
Nco ntsoov, nws yog ib qho tseem ceeb kom ua raws li cov chaw tsim khoom cov lus qhia thiab cov lus qhia tshwj xeeb rau cov yeeb nkab HDPE tshwj xeeb thiab haum koj siv. Tsis tas li ntawd, yog tias koj tsis tau paub txog hauv HDPE yeeb nkab installation, nws raug nquahu kom sab laj tus kws tshaj lij lossis xa mus rau cov lus qhia txog kev teeb tsa los ntawm cov chaw tsim khoom.
