Bellows rau precision txuam ntawm ntsuas thiab meters
Bellows rau precision sib piv ntawm cov twj paj nruag thiab meters yog qhov tseem ceeb ntawm cov khoom siv hauv kev ntsuas. Lawv cov txiaj ntsig tseem ceeb yog nyob rau hauv qhov tseeb thiab ntseeg tau hloov pauv ntawm lub cev kom muaj nuj nqis rau hauv kev ntsuas kev siv tshuab, lossis muab kev sib khi, kev sib txuas, lossis kev them nyiaj. Lawv ua lub luag haujlwm txiav txim siab hauv qhov tseeb, ruaj khov, thiab kev pabcuam lub neej ntawm cov cuab yeej.
Cov ntawv thov tseem ceeb, cov kev xav tau, thiab cov yam ntxwv ntawm lub tshuab raj rau precision ntsuas yog raws li hauv qab no:
Core Functions & Roles
Nyob rau hauv cov twj paj nruag, bellows feem ntau ua lub luag haujlwm tseem ceeb hauv qab no:
Precision Measuring Element
- Muaj nuj nqi:Ua hauj lwm raws li lub ntsiab lus ncaj qha rau siab, nqus tsev, los yog quab yuam.
- Txoj Cai:Hloov cov feeb hloov hauv siab lossis quab yuam mus rau qhov tseeb axial hloov chaw. Qhov kev hloov pauv no tuaj yeem kis tau los ntawm kev ua kom nrov nrov xws li levers lossis lub zog rau lub pointer (hauv cov cuab yeej siv tshuab), lossis hloov mus rau hauv cov teeb liab hluav taws xob los ntawm cov khoom siv hluav taws xob (xws li LVDT - Linear Variable Differential Transformer).
- Piv txwv:Precision pressure gauges, absolute siab gauges, sib txawv siab transmitters.
Sealing thiab Isolation Element
- Muaj nuj nqi:Tiv thaiv lub ntsuas qhov tseem ceeb ntawm lub tshuab txav thaum ntsuas corrosive, viscous, crystallizing, lossis siab -purity media.
- Txoj Cai:Lub tshuab nqus tsev cais tawm tag nrho cov cuab yeej ntsuas ntsuas los ntawm cov txheej txheem kev tshaj tawm, thaum hloov pauv hloov siab.
- Piv txwv:Diaphragm foob ntsuas ntsuas, cov khoom tseem ceeb hauv cov tshuab foob.
Kub Compensation Element
- Muaj nuj nqi:Counteracts yuam kev nyob rau hauv ntsuas ntsuas los ntawm ambient kub hloov.
- Txoj Cai:Siv cov ntaub ntawv uas muaj cov thermal expansion coefficients los ua kom compensating bellows los yog bimetallic strips, uas nws hloov chaw cia li offsets qhov ntxiv hloov chaw ntawm lub hauv paus sensing caij vim kub variations.
- Piv txwv:Sab hauv siab -precision siab ntsuas thiab sensors.
Flexible Connection thiab Vibration Absorption
- Muaj nuj nqi:Kev them nyiaj rau qhov tsis raug me me, kev nthuav dav thermal, lossis kev co hauv cov kav dej.
- Txoj Cai:Siv nws yooj yim los nqus cov microscopic displacements thiab vibrations nyob rau hauv ntau cov lus qhia, tiv thaiv precision ntsuas kev sib txuas thiab cov qauv sab hauv.
- Piv txwv:Kev sib txuas piping ua ntej sensors, lub tshuab nqus tsev connectors.
Kev xav tau siab heev rau Bellows
Raws li lawv siv nyob rau hauv precision ntsuas ntsuas, qhov yuav tsum tau rau cov bellows yog deb npaum li cas stringent tshaj cov kev siv rau kev lag luam tswj kev siv:
High Precision thiab rhiab heev
- Tsawg Hysteresis: Qhov kev hloov pauv - lub zog nkhaus thaum lub zog siab thiab depressurization yuav tsum zoo sib xws, tsis txhob thim rov qab.
- Kev rov ua tau zoo dua: Tom qab suav tsis txheeb, qhov tso tawm tawm rau tib tus nqi siab yuav tsum nyob twj ywm.
- Linearity: Kev sib raug zoo ntawm kev hloov pauv thiab siab yuav tsum yog qhov zoo tshaj plaws kom ua tau yooj yim calibration thiab nyeem ntawv.
Zoo heev Elastic Properties
- Stiffness: Lub zog coefficient ntawm lub tshuab nqus tsev yuav tsum nyob ruaj khov nyob rau hauv cov khoom tag nrho cov kev pab cuam lub neej.
- Zero Creep / Low Relaxation: Kev hloov pauv tsawg kawg hauv cov duab thiab kev ua haujlwm nyob rau hauv lub sijhawm ntev - load.
Super Long Fatigue Lub Neej
Ntau lub cuab yeej xav tau kev ua haujlwm tas mus li, thiab lub tshuab nqus tsev sab hauv tau txais micro-amplitude vibrations nrog cov txheej txheem siab hloov pauv. Yog li ntawd, lawv yuav tsum tiv taus ntau lab lossis ntau pua lab lub voj voog yam tsis muaj kev qaug zog.
Sealing zoo heev
Gas nruj nruj los yog kua nruj yuav tsum tau lav. Ib qho me me tuaj yeem ua rau qhov ntsuas tsis raug lossis ntsuas ntsuas tsis ua haujlwm. Txoj kev tshawb nrhiav nruj xws li helium huab hwm coj spectrometry xau nrhiav pom feem ntau yog ua haujlwm.
Khoom Compatibility thiab Stability
Cov ntaub ntawv yuav tsum tau sib haum nrog cov xov xwm uas lawv hu, nyob ruaj khov, tsis yog - sib nqus los yog qis - sib nqus (kom tsis txhob cuam tshuam), thiab corrosion- tiv taus.
Cov khoom siv feem ntau muaj xws li:300 series stainless hlau (xws li, 304, 316L), Hastelloy, Inconel, phosphor bronze, beryllium tooj liab, thiab lwm yam. Beryllium tooj liab yog dav siv nyob rau hauv siab -kawg seev vim nws zoo heev elasticity, lub zog, thiab qaug zog kuj.
