Expansion pob qij txha, tseem hu ua compensators los yog expansion pob qij txha, muaj ib tug bellows (ib tug elastic element) raws li nws lub ntsiab ua hauj lwm tivthaiv, nrog rau kawg kav, kev txhawb nqa, flanges, conduits, thiab lwm yam accessories. Cov pob qij txha nthuav dav yog cov qauv hloov pauv tau nruab rau ntawm lub thawv ntim lossis cov kav dej kom them nyiaj rau kev ntxhov siab ntxiv los ntawm qhov kub thiab txias thiab kev vibrations. Lawv siv qhov kev nthuav dav zoo thiab kev cog lus deformation ntawm lub hauv siab kom nqus qhov hloov pauv hauv cov kav dej, cov kav dej, thiab cov ntim khoom los ntawm thermal expansion thiab contraction, los yog los them rau axial, lateral, thiab angular displacements. Lawv kuj tuaj yeem siv rau kev txo suab nrov thiab kev co damping, thiab hauv cov tshuab cua sov. Txhawm rau tiv thaiv cov raj xa dej deformation lossis kev puas tsuaj vim thermal expansion lossis kub ntxhov siab thaum cov kav dej kub cua sov, cov khoom siv nyiaj tau los raug ntsia rau hauv cov kav dej kom them nyiaj rau thermal expansion, yog li txo cov kev ntxhov siab ntawm cov yeeb nkab phab ntsa thiab cov rog ua haujlwm ntawm cov khoom siv los yog kev txhawb nqa.
Expansion pob qij txha muaj ib tug kuj yooj yim qauv, muaj xws li ib tug txheej ntawm hlau bellows thiab flanges. Cov hauv qab no yog ua los ntawm cov ntawv nyias nyias thiab muaj corrugated, tso cai rau kev nthuav dav thiab kev cog lus raws li cov kav dej ib txwm ua haujlwm.
Flanges txuas qhov txuas txuas txuas mus rau cov kav dej thiab muaj nyob rau hauv hom ruaj khov thiab txav tau.
Lub ntsiab zoo ntawm expansion pob qij txha yog:
1. Lawv tuaj yeem nthuav dav thiab sib cog lus, txo cov kev ntxhov siab thiab tiv thaiv cov kav dej, li qub, thiab cov khoom siv.
2. Lawv tuaj yeem tiv taus qhov hnyav ib puag ncig xws li kub siab, siab siab, thiab corrosive media, txuas ntxiv cov khoom siv lub neej.
3. Lawv yooj yim rau nruab, tswj, thiab hloov.
4. Lawv kuj yog tus nqi qis thiab muaj lub neej ua haujlwm ntev, ua rau lawv siv thiab tseem ceeb hauv cov raj xa dej.
Txawm li cas los xij, expansion pob qij txha kuj muaj qee qhov tsis zoo:
1. Lawv nce qhov hnyav ntawm lub cev, ua kom cov kev xav tau ntawm cov kav dej txhawb nqa thiab cov qauv.
2. Nws yog ib qho nyuaj rau tswj qhov kev vibration thiab qaug zog tsis ua hauj lwm ntawm lub tshuab nqus tsev twj, uas yuav ua rau muaj kev sib tsoo thiab kev sib tsoo.
Hom ntawm Expansion Joints
- Raws li lawv cov ntaub ntawv thiab cov qauv, cov pob qij txha nthuav dav tuaj yeem muab faib ua ob hom: cov hlau txuas ntxiv thiab cov roj hmab nthuav dav.
- Hlau expansion pob qij txha feem ntau yog ua los ntawm cov ntaub ntawv hlau xws li stainless hlau, tooj liab, thiab txhuas. Lawv cov qauv muaj xws li corrugated expansion pob qij txha, axial expansion pob qij txha, thiab angular expansion pob qij txha.
- Roj hmab expansion pob qij txha feem ntau yog ua los ntawm cov khoom siv roj hmab. Lawv cov qauv muaj xws li spherical expansion pob qij txha, square expansion pob qij txha, thiab cylindrical expansion pob qij txha.
