Kev txhim kho PPR (Polypropylene Random Copolymer) cov yeeb nkab fittings yog ib txoj hauv kev yooj yim uas tuaj yeem ua tiav nrog cov cuab yeej thiab cov txheej txheem. PPR fittings feem ntau yog siv hauv cov kav dej vim lawv cov kav ntev, kev tiv thaiv corrosion, thiab yooj yim ntawm installation. Cov lus qhia no yuav coj koj mus txog cov txheej txheem ib ntus ntawm kev txhim kho PPR yeeb nkab fittings.
Sau cov cuab yeej thiab cov khoom tsim nyog
Ua ntej pib lub installation, xyuas kom tseeb tias koj muaj tag nrho cov cuab yeej tsim nyog thiab cov ntaub ntawv:
- PPR kav thiab fittings
- Tube cutter lossis hacksaw
- PPR vuam tshuab (fusion cuab yeej)
- Ntsuas daim kab xev
- Marker
- Cov hnab looj tes tiv thaiv thiab tsom iav
Muaj tag nrho cov cuab yeej thiab cov ntaub ntawv npaj yuav ua rau cov txheej txheem installation smoother thiab ntau npaum li cas.
Ntsuas thiab txiav cov yeeb nkab
Pib los ntawm kev ntsuas qhov ntev ntawm PPR yeeb nkab xav tau rau koj lub installation. Siv daim kab xev ntsuas kom paub tseeb thiab kos lub ntsiab lus txiav nrog tus cim. Siv cov yeeb nkab cutter los yog hacksaw los txiav cov yeeb nkab kom ntev li ntev tau. Xyuas kom qhov txiav yog ncaj thiab huv si kom haum rau cov fittings. Kev txiav kom huv si yog qhov tseem ceeb rau kev ruaj ntseg thiab kev sib tsoo-pov thawj.
Npaj cov yeeb nkab thiab fittings
Thaum cov yeeb nkab raug txiav, ntxuav qhov kawg kom tshem tawm cov burrs lossis khib nyiab. Qhov no tuaj yeem ua tiav siv lub cuab yeej deburring lossis riam siv hluav taws xob. Ntxuav sab hauv thiab sab nraud ntawm cov yeeb nkab kawg kom ntseeg tau tias qhov chaw du rau vuam. Ib yam li ntawd, ntxuav cov PPR fittings kom tshem tawm cov plua plav lossis cov khoom paug. Kev npaj kom raug ua kom muaj kev sib raug zoo thaum lub sij hawm vuam txheej txheem.
Teem Lub Tshuab Vuam
Teeb tsa koj lub tshuab PPR vuam raws li cov chaw tsim khoom cov lus qhia. Cia lub tshuab ua kom sov txog qhov ntsuas kub, feem ntau nyob ib ncig ntawm 260 degree (500 degree F). Lub tshuab vuam yuav muaj qhov sib txawv me me kom haum rau txoj kab uas hla ntawm cov kav dej thiab fittings koj siv. Txuas cov nozzles tsim nyog rau koj cov yeeb nkab loj thiab cia lawv ncav cuag qhov kub thiab txias.
Weld cov yeeb nkab thiab Fittings
Thaum lub tshuab vuam yog rhuab, ntxig cov yeeb nkab kawg thiab qhov haum rau cov nozzles ib txhij. Tuav lawv nyob rau hauv qhov chaw rau ob peb feeb kom cia cov khoom yaj. Tom qab lub sij hawm cua sov pom zoo, feem ntau nyob ib ncig ntawm 5-7 vib nas this, tshem ob lub yeeb nkab thiab haum ntawm lub nozzles. Ceev nrooj thiab ua tib zoo sib dhos thiab nias lawv ua ke. Tuav qhov sib koom ua ke rau ob peb feeb kom nws txias thiab fuse kom zoo. Rov ua cov txheej txheem no rau tag nrho cov pob qij txha hauv koj lub kav dej.
Tshawb nrhiav Leaks
Tom qab ua tiav qhov kev teeb tsa, nws yog ib qho tseem ceeb los xyuas qhov system rau cov dej xau. Tig rau cov dej xau thiab saib xyuas tag nrho cov pob qij txha kom paub meej tias muaj cov pa tawm. Yog tias pom muaj cov dej xau, xyuas kom cov pob qij txha raug fused kom raug thiab ua kom tsim nyog kho. Kev kuaj xyuas cov dej xau kom ntseeg tau tias muaj kev ntseeg siab thiab kev ncaj ncees ntawm cov kav dej.
Insulate thiab ruaj ntseg cov kav dej
Txhawm rau txhim kho qhov kev ua tau zoo thiab kev ua haujlwm ntev ntawm koj cov kav dej PPR, xav txog kev thaiv cov kav dej. Rwb thaiv tsev pab tswj qhov kub ntawm cov kua uas raug thauj thiab tiv thaiv kom tsis txhob muaj cua sov. Tsis tas li ntawd, ruaj ntseg cov kav dej nrog cov clamps tsim nyog los yog cov hlua khi kom tiv thaiv kev txav thiab kev ntxhov siab ntawm cov pob qij txha. Kev rwb thaiv tsev kom zoo thiab kev ruaj ntseg ntawm cov kav dej ua rau muaj kev ua haujlwm zoo thiab ua haujlwm ntev ntawm lub cev.
Xaus
Kev txhim kho PPR yeeb nkab fittings suav nrog kev ntsuas thiab txiav cov kav dej, npaj qhov chaw, vuam cov pob qij txha, thiab tshuaj xyuas cov dej xau. Nrog rau cov cuab yeej zoo thiab ua tib zoo saib xyuas kom meej, koj tuaj yeem ua tiav cov kav dej ruaj khov thiab ruaj khov. Ua raws li cov kauj ruam no ua kom muaj kev txhim kho tiav thiab kev ua haujlwm ntev ntawm koj cov kav dej PPR. Txawm hais tias siv hauv tsev lossis kev lag luam, PPR yeeb nkab fittings muab cov kev daws teeb meem zoo thiab muaj txiaj ntsig rau cov kav dej niaj hnub xav tau.
