Bellows feem ntau suav nrog cov hlau hauv qab, corrugated expansion pob qij txha, corrugated heat exchange tubes, diaphragm capsules, thiab hlau hoses. Hlau corrugated yeeb nkab yog tsuas yog siv rau kev them nyiaj rau pipeline thermal deformation, poob siab absorbing, thiab absorbing pipeline sinking deformation, thiab yog dav siv nyob rau hauv petrochemical, instrumentation, aerospace, tshuaj, hwj chim, dej txuag, metallurgy thiab lwm yam lag luam. Nws tau ua. Cov kav dej corrugated ua los ntawm cov yas thiab lwm yam khoom siv ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv thaj chaw xws li kev thauj mus los hauv xov xwm, xov hluav taws xob, cov cuab yeej siv tshuab, thiab cov khoom siv hauv tsev.
Bellows: Elastic qhov chaw rau kev ntsuas siab hauv cov cuab yeej ntsuas siab. Lub raj corrugated yog ib lub cylindrical nyias-walled corrugated plhaub nrog ntau yam transverse corrugations, uas yog elastic thiab ua rau kev hloov pauv nyob rau hauv qhov kev txiav txim ntawm siab, axial quab yuam, transverse quab yuam, los yog dabtsi yog khoov lub sij hawm. Masu. Bellows tau siv dav hauv kev ntsuas, thiab lawv lub hom phiaj tseem ceeb yog los ntsuas qhov ntsuas hauv cov twj ntsuas siab uas hloov siab mus rau hauv kev hloov pauv lossis quab yuam. Lub tshuab nqus tsev muaj cov phab ntsa nyias nyias thiab siab rhiab heev, thiab qhov ntsuas ntau yog los ntawm kaum tawm Pascals mus rau ntau kaum ntawm MPa. Tsis tas li ntawd, bellows tuaj yeem siv los ua cov khoom siv hermetic insulating los cais ob qhov xov xwm lossis tiv thaiv cov kua dej tsis zoo los ntawm kev ntsuas qhov ntsuas ntawm lub cuab yeej. Nws kuj tseem siv tau los ua ib qho nyiaj them poob haujlwm uas siv qhov sib txawv ntawm qhov ntim los them rau qhov kub thiab txias hauv cov khoom siv. Qee zaum, nws kuj yog siv los ua ib qho kev sib txuas elastic ntawm ob feem. Cov kav dej corrugated tau muab faib ua cov kav hlau corrugated thiab cov kav hlau tsis yog hlau corrugated raws li lawv cov khoom siv, thiab muab faib ua ib txheej corrugated kav thiab ntau txheej corrugated kav raws li lawv cov qauv. Ib txheej corrugated kav yog dav siv. Multilayer corrugated kav yog siv rau kev ntsuas tseem ceeb vim lawv lub zog siab, ua haujlwm ntev, thiab tsis tshua muaj kev ntxhov siab. Cov khoom siv dav siv rau hauv qab yog tooj liab, tooj dag, stainless hlau, Monel alloy, thiab Inconel alloy.
◆ Siv thaj chaw zoo
Rau cov ntsiab lus elastic uas hloov siab rau hauv kev quab yuam lossis quab yuam rau hauv siab, lwm qhov tseem ceeb ntawm kev ua haujlwm yog qhov chaw zoo. Qhov chaw muaj txiaj ntsig yog hais txog qhov muaj zog ntawm lub zog uas lub zog elastic tuaj yeem hloov mus rau hauv lub zog muaj zog thaum nws qhov kev hloov pauv yog xoom hauv chav tsev siab.
◆ Lub sijhawm ua neej
Muaj ob lub xeev thaum lub caij elastic ua haujlwm: ib qho yog ua haujlwm nyob rau hauv ib qho kev thauj khoom thiab kev txav chaw, thaum ua kom lub load thiab txav mus tas li lossis tsis tshua hloov, uas yog hu ua kev ua haujlwm zoo li qub; Lwm qhov yog siv load thiab txav chaw. hauv lub voj voog. Cov tivthaiv yog nyob rau hauv ib qho kev ua haujlwm cyclic. Vim muaj kev khiav hauj lwm sib txawv, txoj hauv kev uas cov khoom ua puas los yog ua tsis tau kuj txawv. Lub elastic sensing Cheebtsam ntawm cov cuab yeej ua haujlwm nyob rau hauv lub elastic ntau yam thiab feem ntau yog nyob rau hauv ib tug zoo li qub kev khiav hauj lwm lub xeev, thiab muaj ib tug ntev kev pab cuam lub neej, feem ntau mus txog kaum tawm txhiab thiab ntau pua txhiab zaus. Corrugated yeeb nkab qhov chaw siv hauv tshuab qee zaum ua haujlwm hauv elastoplastic ntau lossis nyob rau hauv lub xeev kev ntxhov siab, thiab lawv lub neej kev pabcuam tsuas yog ntau pua zaus. Yog tias cov khoom siv ua haujlwm cyclically, lub neej kev pabcuam yuav tsum tau teev tseg, nrog rau cov lej ntawm lub voj voog, sijhawm thiab zaus.
Lub neej kev pabcuam nominal ntawm lub cev muaj zog yog lub neej kev pabcuam kev xav tau txiav txim siab ntawm tus qauv tsim, uas yuav tsum muaj lub caij kom tsis txhob qaug zog, kev puas tsuaj lossis tsis ua haujlwm thaum lub sijhawm ntawd.
◆ foob
Sealing zog xa mus rau lub peev xwm ntawm cov khoom kom ntseeg tau tias tsis muaj qhov to hauv qab qee qhov sib txawv ntawm sab hauv thiab sab nraud. Thaum lub hauv paus ntsiab lus ua haujlwm, cov kab noj hniav sab hauv yog ntim nrog cov pa roj lossis kua nruab nrab thiab muaj qee qhov siab, yog li nws yog qhov tsim nyog los xyuas kom meej sealing. Cov txheej txheem kev kuaj pom muaj xws li kev ntsuas huab cua siab, ntsuas dej xau, ntsuas kua siab, thiab xab npum dej lossis helium huab cua spectrometer leak detector test.
◆Natural zaus
Qhov chaw ua haujlwm ntawm cov khoom siv elastic siv hauv kev lag luam feem ntau muaj qee qhov kev vibration, thiab qee cov khoom siv los ua kev vibration cais tawm. Nws tus kheej yog nyob rau hauv vibration tej yam kev mob. Rau cov khoom siv elastic siv nyob rau hauv cov ntawv tshwj xeeb, nws yog ib qho tsim nyog yuav tsum ua kom lub cev muaj zog (tshwj xeeb tshaj yog cov zaus zaus) los ntawm kev txav mus rau qhov kev vibration zaus ntawm txhua qhov kev vibration hauv lub cev kom tsis txhob muaj kev cuam tshuam thiab kev puas tsuaj. Bellows Cheebtsam yog dav siv nyob rau hauv ntau yam teb. Txhawm rau kom tsis txhob muaj kev puas tsuaj rau lub tshuab nqus tsev, lub ntuj zaus ntawm lub tshuab nqus tsev yuav tsum qis dua qhov system vibration zaus lossis tsawg kawg 50% siab dua qhov system vibration zaus.
◆ Ua haujlwm kub
Kev khiav hauj lwm kub ntawm cov hlau bellows yog dav heev, uas feem ntau yog teev ua ntej cov khoom elastic yog tsim thiab tsim. Qee qhov tshwj xeeb hauv plab kis tau cov pa oxygen (-196 degree) lossis qis dua cov kua nitrogen los ntawm cov kab noj hniav sab hauv, tiv taus siab txog 25 MPa. Loj corrugated expansion pob qij txha (nominal txoj kab uas hla qee zaum tshaj 1 m) siv los txuas cov kav dej yuav tsum tiv taus siab ntawm 4 MPa, qhov kub ntawm 400 degree thiab qee qhov kev tiv thaiv corrosion. Qhov kub hloov ntawm cov khoom elastic nyob ntawm qhov kub tsis kam ntawm cov khoom siv elastic siv. Yog li, raws li kev khiav hauj lwm kub ntawm cov khoom elastic, tsuas yog xaiv cov ntaub ntawv elastic nrog cov yam ntxwv ntawm qhov kub thiab txias tuaj yeem tsim cov khoom sib xws.
