Raws li cov khoom siv tseem ceeb hauv kev tswj hwm kev lag luam automation,cov khoom xa tawm siabFeem ntau ntsib cov chaw ntsuas hnyav hauv cov txheej txheem niaj hnub xws li roj av, tshuaj lom neeg, fais fab, khoom noj, thiab tshuaj. Nws lub diaphragm sensor tsis yog tsuas yog lub ntsiab lus sensing rau kev xa siab xwb tab sis kuj yog thawj kab ntawm kev tiv thaiv, cais cov txheej txheem nruab nrab ntawm cov kua dej sab hauv thiab tiv thaiv kev puas tsuaj ntawm sensor. Kev tshawb fawb khoom siv thiab kev tsim qauv ntawm diaphragm yog qhov tseem ceeb rau kev daws teeb meem kev ua haujlwm nyuaj. Kev xaiv tsis raug tuaj yeem ua rau muaj teeb meem xws li kev ntsuas tsis sib xws mus rau diaphragm perforation, cov khoom siv pov tseg, thiab txawm tias muaj kev nyab xeeb. Kev xaiv lub tshuab xa siab kom raug yog ib kauj ruam tseem ceeb hauv kev ua kom ntseeg tau tias kev ua haujlwm ruaj khov, txhim khu kev qha thiab pheej yig ntawm tag nrho cov txheej txheem ntsuas.
Cov Yam Ntxim Saib Xyuas Tshuaj ntawm Drive Diaphragm Xaiv
Qhov sib xws ntawm cov tshuaj lom neeg ntawm cov khoom siv diaphragm yog qhov yuav tsum tau ua ua ntej rau kev xaiv qauv. Cov xov xwm sib txawv muaj cov txheej txheem xeb sib txawv ntawm cov khoom siv hlau, xav tau kev tshuaj xyuas raws li lawv cov tshuaj lom neeg thiab cov khoom corrosive. Rau cov xov xwm corrosive heev xws li cov kua qaub muaj zog thiab alkalis, cov hlau tsis xeb 316L feem ntau yuav tsis ua tau raws li qhov yuav tsum tau ua kom ruaj khov mus sij hawm ntev. Piv txwv li, hauv cov chaw muaj sulfuric acid lossis phosphoric acid ntawm chav tsev kub, Hastelloy C-276 dhau los ua qhov kev xaiv zoo tshaj plaws vim nws qhov kev tiv thaiv zoo heev rau corrosion los ntawm kev txo cov xov xwm. Tantalum diaphragm qhia txog yuav luag tag nrho cov tshuaj inertness thaum raug rau cov xov xwm oxidizing muaj zog heev xws li nitric acid, tab sis tus nqi siab feem ntau txwv nws daim ntawv thov rau cov sijhawm tshwj xeeb xws li cov tshuaj zoo lossis cov tshuaj purity siab. Hauv kev tsim kho marine lossis cov chaw muaj chlorides, chloride ions tuaj yeem ua rau pitting corrosion hauv cov hlau tsis xeb ib txwm muaj. Ntawm no, Monel tau txais dav dav vim nws muaj peev xwm passivation zoo heev hauv dej hiav txwv thiab brine kua.
Lub Xeev Lub Cev Nruab Nrab Qhia Txog Cov Qauv Diaphragm
Lub cev ntawm cov khoom nruab nrab (piv txwv li, viscosity, cov khoom khov) cuam tshuam ncaj qha rau kev xaiv cov qauv ntawm diaphragm. Rau cov khoom nruab nrab uas viscous heev lossis yooj yim rau crystallization, cov qauv ib txwm muaj nrog qhov nkag siab me me yuav yooj yim rau kev txhaws, ua rau kev xa mus rau qhov siab tsis ua haujlwm.Tsim cov diaphragm tiaj tussiv tau rau hauv cov xwm txheej zoo li no uas tshem tawm qhov chaw siab thiab tso cai rau lub diaphragm kov lub nruab nrab ncaj qha. Lub qauv flush mount tsis yog tsuas yog tiv thaiv kev txhaws xwb tab sis kuj ua tau raws li qhov yuav tsum tau tsim qauv huv hauv kev lag luam zaub mov thiab tshuaj vim nws tsis muaj thaj chaw tsis khov. Thaum cov nruab nrab muaj cov khoom khov, lub diaphragm ntsib kev pheej hmoo loj ntawm kev hnav. Cov diaphragms ceramic tuaj yeem tiv taus kev yaig ntawm cov khoom me me vim lawv qhov nyuaj heev thiab kev tiv thaiv kev hnav. Qee qhov kev siv hnyav kuj tseem siv cov diaphragms flush tawv kom ntev lub neej kev pabcuam khoom siv hauv qab cov xwm txheej hnyav.
Kev Hloov Kho Rau Cov Xwm Txheej Ua Haujlwm Hnyav
Hauv cov txheej txheem kub siab, kev ua haujlwm thermodynamic ntawm lub rooj sib dhos sensor yog qhov tseem ceeb heev. Cov kua dej sau yuav tsum yog roj silicone kub siab kom tiv thaiv kev ua pa ntawm cov khoom xa tawm siab, ua ke nrogcov ntsaws ruaj ruaj capillary deb, cov khoom txiaslossis lwm yam kev ntsuas cua sov kom tiv thaiv cov khoom siv hluav taws xob los ntawm kev puas tsuaj los ntawm qhov kub siab. Cov ntawv thov uas muaj cov ntsiab lus hydrogen ntau yuav tsum tau cov diaphragms kub-plated kom tiv thaiv hydrogen embrittlement. Hauv cov xwm txheej uas qhov siab nruab nrab hloov pauv hnyav (piv txwv li, thaum lub qhov dej siab nyob ze rau lub twj tso kua mis), kev txhim kho lub pulsation damper yuav tsum tau txiav txim siab los txo qhov kev hloov pauv ntawm lub teeb liab.
