Kev faib tawm los ntawm cov qauv.
1. Ib hom zoo tib yam expansion sib koom ua ke
(1) Ib hom zoo tib yam expansion sib koom tes nrog khi pas nrig: siv los nqus cov kev hloov pauv sab nraud thiab axial hloov chaw hauv cov pas nrig.Qhov tshwj xeeb yog tias cov pas nrig rub tuaj yeem nqus tau lub zog tsim los ntawm lub siab, tab sis qhov ntev ntawm lub hauv siab yog me me, uas tuaj yeem nqus tau me me rau sab nraud.
(2) Ib hom zoo tib yam expansion sib koom ua ke yam tsis muaj hlua khi: siv los nqus axial hloov chaw.Lub thrust tsim los ntawm lub siab tsis tuaj yeem nqus tau.
2. Ob chav universal expansion sib koom ua ke
(1) Ob chav universal expansion sib koom ua ke nrog khi pas nrig: siv los nqus cov kev hloov pauv sab nraud thiab axial hloov chaw hauv cov pas nrig.Qhov ntev ntawm qhov ntev ntawm ob pawg ntawm ripples yog, ntau qhov kev hloov pauv sab nraud yuav raug nqus, tab sis qhov nro kuj yuav nce ntxiv.Vim qhov kev txwv nruj, lub pas nrig rub tsis tuaj yeem ntev dhau.
(2) Compound square expansion sib koom ua ke nrog luv nro: siv los nqus rau sab nraud thiab axial hloov chaw.Txij li thaum tsis muaj kev txwv ntawm rub pas nrig, qhov ntev ntawm ob pawg ntawm bellows tuaj yeem ntev heev, yog li nws tuaj yeem nqus tau loj rau sab nraud thiab axial hloov chaw.Txawm li cas los xij, qhov thrust generated los ntawm lub siab yuav tsum tau yug los ntawm lub ntsiab ruaj ruaj.
3. Ib hom saw expansion sib koom ua ke
(1) Planar ib leeg saw expansion pob qij txha: feem ntau siv nyob rau hauv L-shaped, n-shaped thiab planar 2-puab cov kav dej, ntau tshaj li ob txoj hlua txuas txuas ntxiv tau teeb tsa kom nqus cov kev hloov pauv sab nraud thiab axial hloov chaw, thiab qhov thrust tsim los ntawm lub siab. yog absorbed los ntawm cov saw hlau.
(2) Universal ib leeg hom kev nthuav dav sib koom ua ke tuaj yeem nqus cov angular txav mus rau txhua qhov kev taw qhia.Nws feem ntau yog ua ke nrog ib qho kev sib txuas sib txuas rau cov khoom z-shaped yeeb nkab, uas yog tuab thiab loj.
4. Rov ua dua cov saw txuas ntxiv
(1) Lub dav hlau txuas txuas txuas txuas txuas yog siv rau L-shaped thiab dav hlau 2-zoo li cov kav dej kom nqus cov xaim sab nraud.Lub rub phaj yog nruj dua li qhov ntev rub pas nrig ntawm cov khoom sib xyaw universal.Lub phaj rub ntev ntev tuaj yeem siv los nqus ntau qhov kev hloov pauv sab nraud thiab axial hloov chaw.Nws qhov tsis zoo yog tias nws tsuas tuaj yeem nqus tau qhov txav ntawm lub dav hlau.
(2) Universal compound saw hom expansion sib koom ua ke tuaj yeem nqus cov kev hloov pauv hauv txhua qhov kev taw qhia vim siv cov pin blocks hauv cov saw hlau.Nws yog feem ntau siv rau qhov siab z-shaped kav.
Kev faib tawm los ntawm kev siv.
1. Axial expansion sib koom ua ke
Ib qho expansion sib koom siv los nqus axial hloov chaw.Feem ntau muaj ob hom ntawm ib qho yooj yim expansion pob qij txha tsis khi rods thiabaxial expansion pob qij txha.Nyob rau hauv qhov kev txiav txim ntawm sab nraud txhais tes siab, cov kem stability ntawm expansion sib koom ua ke zoo dua li nyob rau hauv lub siab.Txawm li cas los xij, cov qauv ntawm axial expansion sib koom ua ke nyob rau hauv lub siab sab nraud yog qhov nyuaj dua.Ib zaug, axial expansion sib koom ua ke nyob rau hauv lub siab sab nraud yog siv tsuas yog thaum muaj ntau yoj tus lej yuav tsum tau thiab kem instability yuav tshwm sim nyob rau hauv lub siab.
2. Transverse displacement expansion sib koom ua ke
Ib qho expansion sib koom siv los nqus transverse hloov chaw.Feem ntau muaj ntau yam kev nthuav dav thoob ntiaj teb, cov pob qij txha nthuav dav zoo tib yam nrog cov hlua khi, thiab ntau cov hlua txuas ntxiv.
3. Angular displacement expansion sib koom ua ke
Ib qho expansion sib koom siv los nqus angular hloov chaw.Nws yog feem ntau chain expansion sib koom ua ke.Ob los yog ntau tshaj yog feem ntau siv ua ke los nqus lateral displacement.
4. Siab sib npaug expansion sib koom ua ke
Nws tuaj yeem sib npaug ntawm qhov kev sib tw uas tsim los ntawm lub siab, thiab siv rau hauv cov xwm txheej uas tsis tso cai loj.Cov hom tseem ceeb yog lub luj tshib siab balanced expansion sib koom ua ke, ncaj yeeb nkab siab expansion sib koom thiab bypass siab balanced expansion sib koom.
5. Kub kub expansion sib koom ua ke
Nyob rau hauv dav dav, lub hauv paus ntsiab lus ntawm expansion sib koom ua ke, ua hauj lwm nyob rau hauv high-kev ntxhov siab, thiab cov khoom siv bellows yog nquag nkag mus rau ntawm qhov kub thiab txias, uas zoo heev txo lub neej qaug zog.Yog li ntawd, thaum qhov nruab nrab kub siab tshaj qhov kub ntawm cov khoom siv corrugated yeeb nkab, yuav tsum tau siv cov txheej txheem rwb thaiv tsev, xws li kev sib koom ua ke ntawm lub tshuab hluav taws xob tawg lossis cov txheej txheem ntawm chav txias, xws li kev sib koom ua ke, kom txo tau. phab ntsa kub ntawm cov khoom siv corrugated yeeb nkab thiab ua rau cov yeeb nkab corrugated ua haujlwm ntawm qhov kub thiab txias.
