Micro-perforated phaj silencers yog dav siv nyob rau hauv qhov cua thiab cua txias systems, gas turbine intake thiab tso systems, thiab industrial pipeline suab tswj vim lawv cov qauv yooj yim, kub tsis kam, corrosion kuj, thiab dav -band suab nrov txo cov yam ntxwv. Txhawm rau kom lawv ua tiav qhov kev xav tau ntawm lub suab nrov txo cov txiaj ntsig hauv kev ua haujlwm tiag tiag thiab ua tau raws li kev tsim qauv tsim qauv, cov txheej txheem kev soj ntsuam nruj thiab kev tshawb fawb yog qhov tseem ceeb. Kab lus no yuav tham txog cov kauj ruam tseem ceeb ntawm kev sim rau micro-perforated phaj silencers.
Thawj kauj ruam hauv cov txheej txheem sim yog qhov kev tshuaj xyuas zoo. Cov neeg ua haujlwm yuav tsum txheeb xyuas qhov ntsuas qhov ntev, phaj tuab, thiab qhov ntsuas aperture tiv thaiv cov duab kos. Lub hom phiaj yog los xyuas seb qhov perforation npaum li cas ntawm micro-perforated phaj ua tau raws li qhov yuav tsum tau ua, seb qhov kev npaj lub qhov zoo li cas thiab zoo, thiab seb puas muaj kev thaiv lossis deformations. Nyob rau tib lub sijhawm, qhov zoo ntawm lub plhaub welds yuav tsum tau kuaj xyuas kom ntseeg tau tias tsis muaj qhov tsis tiav welds, cuav welds, los yog tawg, thiab flange interface flatness yuav tsum ua tau raws li cov qauv kev sib khi. Qhov kev ntsuam xyuas yooj yim no yog qhov yuav tsum tau ua ua ntej kom ntseeg tau tias tus neeg nyob hauv lub cev daim foos ua tau raws li qhov yuav tsum tau ua ntawm daim ntawv thov engineering.
Tom qab ntawd, qhov tseem ceeb acoustic kev ua tau zoo theem pib pib. Kev ntsuam xyuas feem ntau yog ua nyob rau hauv impedance raj los yog semi- anechoic chamber ib puag ncig, nrog rau kev xeem zaus bands teem raws li lub teb chaws tus qauv. Thaum kuaj, ob qhov kawg ntawm lub suab yuav tsum tau muab khi rau lub suab nrov thiab tau txais cov kav dej kom tshem tawm cov suab nrov ntawm ib puag ncig. Ib lub suab nthwv dej tshwj xeeb yog tsim los siv lub tshuab hluav taws xob teeb liab, thiab qhov xwm txheej thiab kev xa suab nrov raug ntsuas los ntsuas qhov kev sib kis. Ib tug tsim nyog micro-perforated phaj silencer yuav tsum muaj ib tug ruaj khov thiab siab insertion poob nkhaus nyob rau hauv nws tsim zaus band, tshwj xeeb tshaj yog qhia tau hais tias zoo resonant suab absorption yam ntxwv nyob rau hauv qis - zaus ntau. Yog hais tias cov ntaub ntawv ntsuas deviates los ntawm tus nqi tsim los ntawm ntau tshaj qhov tso cai, qhov ua rau yuav tsum tau soj ntsuam thiab cov qauv optimized.
Kev ntsuas kev ua haujlwm aerodynamic raws li nram no. Cov kauj ruam no tsuas yog ntsuas lub suab nrov qhov cuam tshuam ntawm airflow tsis kam, tshwj xeeb los ntawm kev ntsuas nws qhov poob siab ntawm cov ntsuas cua. Lub kaw lus xeem muaj xws li kiv cua, ntws tswj valve, micromanometer, thiab lub nplhaib siab. Lub airflow tshaj tawm yog tswj los ntawm kev kho lub valve, thiab qhov sib txawv ntawm qhov sib txawv ntawm cov dej ntws sib txawv tau sau tseg. Vim hais tias micro-perforated phaj silencers tsis muaj suab-absorbing khoom, lawv cov ndlwg tsis kam yog feem ntau qis, tab sis nws yuav tsum tau xyuas kom meej tias lub siab poob tsis cuam tshuam rau lub zog noj thiab airflow faib ntawm lub qhov cua. Rau qhov loj -size silencers, flow velocity distribution uniformity verification tseem yuav tsum tau tiv thaiv kom tsis txhob muaj suab nrov los ntawm lub zos eddies.
Thaum kawg, kev txheeb xyuas qhov kev hloov pauv ib puag ncig yog ua rau cov ntawv thov tshwj xeeb. High -kub silencers yuav tsum tau kuaj thermal aging nyob rau hauv tas li -temperature chamber los ntsuam xyuas lawv structural stability thiab acoustic kev ua tau zoo degradation tus nqi nyob rau hauv sustained kub. Corrosion-cov khoom tiv thaiv tau dhau los kuaj cov tshuaj ntsev kom simulate ib puag ncig hnyav thiab txheeb xyuas qhov ua haujlwm ntev ntawm txheej txheej txheej txheej. Tag nrho cov ntaub ntawv xeem yuav tsum tau sau kom ntxaws, txheeb xyuas, thiab muab piv rau daim ntawv tshaj tawm kev xeem, uas yog lub hauv paus rau kev lees paub cov khoom thiab kev xaiv engineering.
Hauv cov ntsiab lus, cov txheej txheem sim rau micro-perforated phaj silencers npog tag nrho cov txheej txheem los ntawm geometric parameter pov thawj mus rau acoustic thiab aerodynamic kev ua tau zoo validation. Kev ua raws li cov txheej txheem no tsis yog tsuas yog ua kom cov khoom zoo xwb tab sis kuj muab kev txhawb nqa tseem ceeb rau kev ua tiav cov suab nrov nrov thiab txhim kho lub zog ua haujlwm. Cov kws tshaj lij hauv kev lag luam yuav tsum hais txog cov txheej txheem ntawm kev sim cov txheej txheem thiab cov ntaub ntawv traceability los sib koom ua ke txhawb kev nce qib thiab kev siv cov cuab yeej siv suab nrov.
