1. Taw qhia: Vim li cas Thermal nthuav dav hauv cov kav dej yas
Hauv kev lag luam piping tshuab, tswj hwmThermal nthuav davyog tseem ceeb - Tshwj xeeb tshaj yog thaum cuam tshuam nrog cov khoom siv thermoplastic xws liPPH (polypropylene homopolymer)Cov. Raws li qhov kub hloov ua tiav, cov kav dej nthuav dav thiab cog lus, uas tuaj yeem ua rauKev ntxhov siab, deformation, lossis tsis ua tiavYog tias tsis yog nyob. PPH cov fittings raug tsim los tsis tsuas yog siv rau cov tshuaj tiv thaiv kev tiv thaiv thiab cov tshuab muaj zog tab sis kuj tseemMuv qhov cuam tshuam ntawm thermal expansion, txhawm rau kev nyab xeeb system thiab ntev.

2. Thermal nthuav kev coj cwj pwm ntawm PPH cov ntaub ntawv
Pph, xws li txhua yam thermoplastics, nthuav dav ntau dua li hlau thaum raug kom sov. NwsLINEAR THERMAL PROVAL nthuav tawm coefficientyog kwv yees li0.15 mm / m / degree, uas txhais tau tias yog 10-meter yeeb nkab tuaj yeem nthuav tawm ntau dua 15 hli nrog tsuas yog 10℃Kub nce. Tus cwj pwm no yuav tsum yogXav Tau Hauv Kev Tsim Qauv Txheej Txheem, tshwj xeeb tshaj yog nyob rau hauv cov dej kub siv cov kab. Yog tias tsis muaj lwm tus, qhov kev nthuav dav no tuaj yeem ua raucov yeeb nkab buckling, kev ua haujlwm tsis ua haujlwm, lossis misalignmentSijhawm dhau sijhawm.

3. Kev tsim kho cov tswv yim rau kev tswj cov cua sov
Txhawm rau hais txog kev nthuav dav thiab kev cog lus hauv cov kab ppping pping, ob peb cov kev txhim kho kev txhim kho engineering) yog siv:

Kev nthuav dav dav thiab offsets: Cov no cia cov yeeb nkab txav ib txwm tsis muaj kev cuam tshuam kev ntxhov siab ntawm fittings lossis txhawb nqa.

Anchors thiab cov lus qhia: Tawg thauj tog rau nkoj cov ntsiab lus thiab cov lus qhia taw qhia kev tswj cov yeeb nkab cov qauv hluav taws xob thiab ua kom muaj kev nthuav dav tshwm sim hauv kev nyab xeeb.

Saj zawg zog sib txuas thiab nthuav tawm pob qij txha: Cov feem sib xyaw nqus cov zog nthuav dav thiab tiv thaiv cov fittings rigid los ntawm kev txav ntau dhau.

Tsim nyog spacing ntawm kev txhawb nqa: Minimizing yeeb nkab thiab tso cai rau cov kev tshem tawm thermal txuag hluav taws xob.

Cov tswv yim no yog qhov tseem ceeb tshaj plaws hauvsaum toj - av thiab siab -} kub txhim kho.

4. Lub luag haujlwm ntawm pph fittings hauv kev tswj cov hluav taws xob thermal
PPH cov fittings yog tsim nrogQhov tseeb ntawm qhov tseeb thiab kev kub siab kub, ua rau lawv kom tswj cov ntsaws ruaj ruaj thiab cov kev sib ncag txawm tias thaum lub sij hawm nthuav dav. Cov txiaj ntsig tseem ceeb muaj xws li:

Raws li Weld Zoo(hauv qhov (hauv) thiab pob tw fusion pob qij txha) uas tuaj yeem ua kom haum cov kev ntxhov siab thermal tsis muaj kev tawg.

Tsawg thermal conductivity, uas yuav pab txo tus nqi ntawm cov cua sov hloov thiab cua sov.

Muaj cov khoom siv muaj zoguas tiv thaiv kev tawm tsam lossis distortion.
Ua ke, cov khoom no pab kom puas ntseegMuaj kev nyab xeeb ntev - kev ua haujlwm, txawm tias nyob rau hauv cov cua tshuab cua sov thiab cua txias.

5. Kev siv kev lag luam uas thermal nthuav kev tswj yog qhov tseem ceeb
PPH cov txheej txheem tau siv dav hauv cov ntawv thov uas xav tau ob qho tib siTshuaj KujthiabKev Ua Si Kub Kub, xws li:

Tshuaj Kub Tshuaj Pab KabHauv kev ua cov nroj tsuag

Kev Tso Cai Nuj Nqis Tso Tsheb Hlau Luamqhov twg ua rau cov tshuaj tiv thaiv exothermic tshwm sim

Hnub Ci Cua Sov Tshuab

Khoom Noj Khoom Haus thiab Dej Hausqhov twg tu yog dej kub lossis dej
Hauv txhua ntawm cov no, ceev faj thermal nthuav kev tsim qauv siv pph ntseeg txoj kev ntseeg tau, tiv thaiv kev tu tus nqi, thiab txhawb nqa kev ua raws cai nrog cov qauv engineering.

Kev tswj kom zoo ntawm kev nthuav dav hluav taws xob yog qhov tseem ceeb rau covkev ua tau zoo thiab cov kav dej ruaj khov ntawm cov roj hmab yas, tshwj xeeb tshaj yog nyob rau hauv kev txhoj puab heev thiab siab - qhov chaw ib puag ncig. PPH cov fittings muab kev sib txuas ntawmTshuaj lom neeg Kuj, Kub Daus, thiab Cov Qauv Txheej Txheem, ua rau lawv zoo tagnrho rau cov kab ke uas thermal txav yuav tsum tau tswj hwm. Los ntawm kev sib xyaw ua ke cov qauv tsim kom zoo thiab high- Cov khoom tuab}} paab cov kws engetents no tuaj yeem tsim cov kav dej uas yog ob qho tib siresilient thiab ntev - kav{{0- Txawm nyob rau hauv feem ntau xav tau cov mob.
