Corrugated yeeb nkab compensator tseem hu ua expansion sib koom ua ke thiab expansion sib koom ua ke, feem ntau yog siv los xyuas kom meej pipeline lag luam.
Bellows compensator yog ib qho yooj yim, nyias-walled, transversely corrugated ntaus ntawv nrog expansion muaj nuj nqi, uas yog tsim los ntawm hlau bellows thiab cov khoom.Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab nqus dej twj tso kua mis yog tsuas yog siv nws cov elastic expansion muaj nuj nqi los them cov axial, angular, lateral thiab sib xyaw ua ke ntawm cov kav dej vim thermal deformation, mechanical deformation thiab ntau yam kev vibrations.Cov kev them nyiaj ua haujlwm suav nrog kev ua haujlwm siab, kev sib khi, kev tiv thaiv corrosion, kub tsis kam, cuam tshuam tsis kam, kev poob siab thiab suab nrov txo, uas tuaj yeem txo cov kav dej deformation thiab txhim kho lub neej kev pab cuam ntawm cov kav dej.
Txoj Cai Ua Haujlwm
Lub ntsiab elastic ntawm lub corrugated compensator yog stainless hlau corrugated yeeb nkab, uas yog siv los them nyiaj rau axial, transverse thiab angular kev taw qhia ntawm cov kav dej nyob ntawm qhov nthuav thiab khoov ntawm cov yeeb nkab corrugated.Nws txoj haujlwm tuaj yeem yog:
1. Txhawb cov axial, transverse thiab angular thermal deformation ntawm cov yeeb nkab haum.
2. nqus cov khoom vibration thiab txo qhov cuam tshuam ntawm cov khoom siv vibration ntawm cov kav dej.
3. Ncua qhov deformation ntawm cov raj xa dej los ntawm av qeeg thiab av qeeg.
Lub compensator tuaj yeem muab faib ua unconstrained bellows compensator thiab constrained bellows compensator raws li seb nws puas tuaj yeem nqus tau lub siab thrust (dig muag phaj quab yuam) tsim los ntawm qhov nruab nrab siab hauv cov kav dej;Raws li daim ntawv hloov chaw ntawm lub tshuab nqus tsev, nws tuaj yeem muab faib ua axial type compensator, transverse type compensator, angular type compensator thiab pressure balance type bellows compensator.
Cov xwm txheej ntawm kev siv
Hlau bellows compensator yog tsim los ntawm kev tsim, kev tsim khoom, kev teeb tsa, kev tswj xyuas kev ua haujlwm thiab lwm yam txuas.Yog li ntawd, kev ntseeg siab yuav tsum tau txiav txim siab los ntawm cov yam no.Ntxiv rau nws cov kev ua haujlwm zoo, nws qhov nruab nrab, qhov kub thiab txias ntawm qhov chaw sab nraud, nrog rau kev ntxhov siab corrosion, tus neeg saib xyuas dej, thiab lwm yam, yuav tsum tau txiav txim siab thaum xaiv cov khoom siv rau corrugated yeeb nkab compensator hauv cov khoom siv hluav taws xob.
Raws li ib txwm muaj, cov ntaub ntawv corrugated yeeb nkab yuav tsum ua raws li cov hauv qab no:
(1) Siab elastic txwv, lub zog tensile thiab qaug zog lub zog los xyuas kom meej lub tshuab ua haujlwm.
(2) Zoo plasticity los pab txhawb kev tsim thiab ua cov kav dej corrugated, thiab los ntawm kev ua haujlwm tom ntej kom tau txais cov hardness txaus thiab lub zog.
(3) Zoo corrosion kuj kom tau raws li qhov chaw ua haujlwm sib txawv ntawm cov kav dej corrugated.
(4) Kev ua haujlwm vuam zoo kom ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem vuam los tsim cov kav dej corrugated.Rau lub trench nteg cua sov yeeb nkab network, thaum lub corrugated yeeb nkab compensator yog immersed nyob rau hauv tsawg-lying kav, los nag los yog dej phwj tuaj, cov ntaub ntawv ntau resistant corrosion tshaj hlau yuav tsum tau xav txog, xws li npib tsib xee alloy, siab nickel alloy, thiab lwm yam.
Kev them nyiaj yug
1. Cov qauv, kev qhia tshwj xeeb thiab kev teeb tsa cov kav dej ntawm lub tshuab hluav taws xob yuav tsum tau kuaj xyuas ua ntej kev teeb tsa, uas yuav tsum ua kom tau raws li cov qauv tsim.
2. Rau compensator nrog lub tes tsho sab hauv, nws yuav tsum tau muab sau tseg tias cov kev taw qhia ntawm lub tes tsho sab hauv yuav tsum ua raws li cov kev taw qhia ntawm nruab nrab ntws, thiab lub pob khawm rotation dav hlau ntawm pob khawm hom compensator yuav tsum zoo ib yam nrog cov kev sib hloov lub dav hlau.
3. Rau cov nyiaj them rov qab uas xav tau "txias txias", cov khoom siv uas siv rau kev deformation ua ntej yuav tsum tsis txhob raug tshem tawm kom txog thaum lub raj xa dej raug teeb tsa.
4. Nws yog txwv tsis pub kho lub installation ntawm lub siab ntev ntawm lub raj xa dej los ntawm kev deformation ntawm lub corrugated compensator, thiaj li tsis cuam tshuam rau lub cev muaj nuj nqi ntawm lub compensator, txo lub neej kev pab cuam thiab nce lub load ntawm lub raj xa dej, khoom siv. thiab txhawb cov tswv cuab.
5. Thaum lub sij hawm installation, vuam slag tsis raug tso cai rau txaws rau saum npoo ntawm yoj rooj plaub, thiab yoj rooj plaub tsis raug tso cai los ntawm lwm yam kev puas tsuaj.
6. Tom qab cov yeeb nkab tau teeb tsa, cov khoom siv hluav taws xob daj daj thiab cov khoom siv txuas ntxiv siv rau kev teeb tsa thiab kev thauj mus los ntawm cov khoom siv hluav taws xob corrugated yuav tsum raug tshem tawm sai li sai tau, thiab cov cuab yeej txwv yuav tsum tau hloov kho mus rau txoj haujlwm tshwj xeeb raws li cov qauv tsim, kom cov yeeb nkab system muaj peev xwm them nyiaj txaus raws li ib puag ncig.
7. Tag nrho cov khoom txav ntawm tus neeg them nyiaj yuav tsum tsis txhob raug thaiv lossis txwv los ntawm cov khoom siv sab nraud, thiab kev ua haujlwm zoo ntawm txhua qhov txav yuav tsum tau ua kom ntseeg tau.
8. Thaum lub sij hawm kuaj hydrostatic, qhov thib ob taag yeeb nkab khib nyob rau hauv qhov kawg ntawm cov kav dej nrog compensator yuav tsum tau ntxiv dag zog los tiv thaiv lub pipeline los ntawm kev txav los yog tig.Rau cov nyiaj them rov qab thiab nws cov kav dej sib txuas siv rau cov pa nruab nrab, ua tib zoo saib seb nws puas tsim nyog ntxiv kev txhawb nqa ib ntus thaum sau dej.Cov ntsiab lus ntawm 96 chloride ion ntawm cov tshuaj ntxuav siv rau kev kuaj hydrostatic yuav tsum tsis pub tshaj 25PPM.
9. Tom qab kev sim hydrostatic, cov dej ntim hauv cov ntaub ntawv yoj yuav tsum tau ntws tawm sai li sai tau thiab cov ntaub ntawv yoj sab hauv yuav tsum tau tshuab kom qhuav.
10. Cov khoom siv rwb thaiv tsev nyob rau hauv kev sib cuag nrog lub hauv siab ntawm lub compensator yuav tsum tsis muaj chlorine.
Cov sijhawm thov
1. Lub raj xa dej nrog loj deformation thiab txwv spatial txoj hauj lwm.
2. Cov kav dej loj loj nrog cov deformation loj thiab hloov chaw thiab ua haujlwm siab.
3. Cov khoom siv uas yuav tsum tau txwv kom thauj khoom.
4. Cov kav dej yuav tsum tau nqus los yog cais cov tshuab hluav taws xob ntau zaus.
5. Cov kav dej yuav tsum tau nqus av qeeg lossis hauv paus kev daws teeb meem.
6. Lub raj xa dej yuav tsum tau nqus cov kev co ntawm lub qhov hluav taws xob ntawm lub raj xa dej.
