Kukonza sipika yolimba kuti igwiritsidwe ntchito pomanga migodi ya PA ndi kuyika sipika ya PA kumatanthauza kumanga mawu amphamvu, osati kuti zigwiritsidwe ntchito powonetsera malo. Malo omanga migodi amatha kukhala ndi phokoso lalikulu, fumbi, mvula, kutentha, komanso kugwiritsa ntchito chingwe kwa nthawi yayitali, kotero zolinga zothandiza kwambiri ndi kumveka bwino kwa mawu, chitetezo cha m'nyumba, komanso kudalirika kwa nthawi yayitali. Mu makina ochenjeza anthu, kumveka bwino nthawi zambiri kumayesedwa ndi njira monga STI, pomwe kulimba kwa chilengedwe nthawi zambiri kumatsimikiziridwa kudzera m'njira mongaASTM G85kuyesa kwa dzimbiri kwa cyclic ndiISO 9227Kuthira mchere. Pokonzekera bwino ntchito, makina amawu omwe sangathe kupirira kufalikira bwino kwa malo ogwirira ntchito, m'mphepete mwa malo osungira, ndi m'malo osungira zinthu sakonzedwa bwino, ngakhale mphamvu yake itakhala yodabwitsa papepala.

Zimene dongosolo la PA la migodi yotseguka ndi okamba nkhani a PA ayenera kuthetsa

Vuto lalikulu ndi mpikisano wa mawu kuchokera ku makina, mtunda, ndi kuwala kwa malo. Migodi yotseguka si malo ofanana; imaphatikizapo malo otsetsereka, mabenchi, zotsukira, malo onyamulira katundu, ndi malo oyang'anira, iliyonse ili ndi mawonekedwe osiyanasiyana a phokoso ndi zoletsa zowonera mzere. Wokamba nkhani wolemera ayenera kuthana ndi zonse zitatu popanda kupanga kusokoneza kwakukulu komwe kumapangitsa kuti kulankhula kukhale kovuta kumva. Ichi ndichifukwa chake mainjiniya ambiri amasankha zokweza mawu zamafakitale zokhala ndi honi kapena zogwira ntchito bwino kwambiri kuti zigwiritsidwe ntchito nthawi yayitali, kenako nkuziphatikiza ndi zoning zakomweko kuti antchito amve mauthenga olunjika m'malo molengeza kutali, kobwerezabwereza.

Kumveka bwino kwa mawu n'kofunika kwambiri chifukwa kuyika mapeji adzidzidzi kumadalira nthawi. NFPA 72 ikugogomezera momwe machitidwe olumikizirana adzidzidzi amagwirira ntchito, ndipo m'malo ambiri ofunikira chitetezo, kuyesa kumvetsetsa kumakhala kofunikira kwambiri kuposa kungoyesa kuchuluka kwa zomwe zatulutsidwa. Ngati uthengawo sungabwerezedwe molondola ndi wantchito pa 100 m phokoso la mphepo ndi makina, dongosololi lalephera cholinga chake. Umenewo ndiye muyezo wothandiza, kaya ntchitoyo ndi njira yotsegulira migodi ya PA, netiweki yotulutsira anthu ku fakitale yonse, kapena siteshoni yowongolera kutali.

Zinthu zomangira zolemera zomwe zimapangitsa kuti phokoso ndi mtunda wa migodi zimveke

Cholankhulira chabwino kwambiri chogwiritsira ntchito migodi ya PA chimalinganiza kutulutsa, kuwongolera, ndi kulimba. Cholankhulira chomwe chimamveka mokweza koma chachikulu kwambiri pofalikira chimawononga mphamvu kupita panja ndi pamalo owunikira. Cholankhulira chomwe chili chopapatiza kwambiri chingapangitse mipata yophimba pamalo osalinganika. Cholinga chake ndi kuwonetsa mawu mowongoka ndi mutu wokwanira kuti ukhale womveka bwino kuposa phokoso lozungulira.

Mu malo enieni osungiramo zinthu, zinthuzi zimagwirira ntchito limodzi. Cholankhulira cha PA chotulutsa mphamvu kwambiri chomwe chili bwino chingatuluke pamalo ofunikira pambuyo pogwedezeka mobwerezabwereza. Chipolopolo cholimba ndi dzimbiri chokhala ndi kapangidwe kofooka ka mawu chingakhale cholimba koma chikalephera kugwira ntchito. Ichi ndichifukwa chake magulu ogula ayenera kufunsa deta yonse ya dongosolo, kuphatikiza ma curve otulutsa, tsatanetsatane woyika, ndi ziwerengero zachilengedwe, osati mphamvu yokha. Kuti mulumikizane ndi mafakitale ambiri, tsamba lingafunikenso zida zogwirizana mongamafoni a mafakitale, mafoni osaphulikandimafoni osagwedezeka ndi nyengokuti ma alarm ndi kulankhulana kwa mawu zikhale zogwirizana.

Momwe mungasankhire chivundikiro cha makina otseguka a PA

Kukonzekera nkhani ndi gawo limodzi losaiwalika kwambiri pakupanga migodi ya PA. Ogula ambiri amayang'ana kwambiri mphamvu ya sipika, koma funso lenileni ndi lakuti anthu amaima pati, zomwe amamva, komanso kangati mauthenga ayenera kuletsa phokoso la zida. M'malo otseguka, kutayika kwa mawu kumakwera mofulumira malinga ndi mtunda, komwe mphepo imalowera, komanso momwe nthaka imayamwa, kotero sipika imodzi yayikulu nthawi zambiri simathetsa vuto lonse.

Njira yabwino ndiyo kugawa malo m'magawo. Kulemba mapeji pogwiritsa ntchito malo kumalola wogwiritsa ntchito kutumiza machenjezo olunjika ku malo ophwanyira, malo onyamulira katundu, kapena msewu wonyamula katundu payekha. Izi zimachepetsa phokoso losafunikira ndipo zimawonjezera kumveka bwino kwa uthenga. Zimathandizanso kukonza, chifukwa malo olephera ndi osavuta kuwasiyanitsa kuposa kulephera kwa dongosolo limodzi lokha.

Ngati mtunda uli wautali, zokuzira mawu zogawidwa nthawi zambiri zimakhala bwino kuposa chipangizo chimodzi chachikulu. Mwachidule, opanga makina nthawi zambiri amagwiritsa ntchito zokamba zingapo za PA zamafakitale pamlingo wotsika m'malo mogwiritsa ntchito gwero limodzi lokha lomwe limayendetsedwa pafupi ndi kusokonekera. Zimenezi zimathandiza kuti chokamba chimodzi chowonongeka chisamathe kulankhulana m'dera lonselo.

Miyezo ndi njira zoyesera zomwe ndizofunikira pa kudalirika kwa okamba nkhani m'mafakitale

Miyezo imasintha zonena zosamveka bwino kukhala zofunikira zoyesedwa. Pa migodi ndi malo ena ovuta a mafakitale, chofunikira ndikutsimikizira kuti cholankhulira ndi choyikiracho zipulumuka malo omwe zidzakumane nawo. Kuyesa dzimbiri nthawi zambiri kumatchulidwa pogwiritsa ntchitoASTM G85, yomwe imafotokoza njira zozungulira zowononga zinthu ndi zokutira. Kupezeka kwa mchere nthawi zambiri kumayesedwa pansi paISO 9227Pa njira zamagetsi ndi zolumikizirana zadzidzidzi,NFPA 72imagwiritsidwa ntchito kwambiri pankhani ya chitetezo cha moyo.

Maumboni awa ndi ofunika chifukwa zida zamigodi sizimakumana ndi mvula yokha. Kulowa kwa fumbi, kuwonongeka kwa UV, kutopa ndi kugwedezeka, ndi kuzizira zonse zimatha kuchepetsa nthawi yogwirira ntchito. Wokamba nkhani amene wapambana mayeso ogwirira ntchito mkati akhoza kulepherabe ngakhale atakumana ndi nyengo. Chifukwa chake, ogula ayenera kufunsa ogulitsa malipoti oyesa, ma ratings a enclosure, ndi malangizo oyika omwe akugwirizana ndi momwe malo alili m'malo movomereza zonena za "kunja".

Poyerekeza, eni malo a mafakitale omwe amayang'aniranso chitetezo cha m'mbali mwa malo akhoza kugwiritsa ntchito zipangizo mongamafoni adzidzidzi a mafakitalendima intercom owongolera mwayipamodzi ndi okamba nkhani a PA. Izi zimapangitsa kuti pakhale njira yolankhulirana yolimba chifukwa zochitika za mawu, alamu, ndi zolumikizira zitha kulumikizidwa m'malo mothandizidwa ndi zida zapadera.

Kuchita bwino kwa mawu: chifukwa chake kumveka bwino kumaposa mphamvu yamagetsi

Mphamvu yopepuka siifanana ndi magwiridwe antchito abwino. Ma speaker awiri a 100 W amatha kuchita zinthu mosiyana kwambiri ngati wina ali ndi mphamvu yabwino, kufalikira kwamphamvu, komanso kusokonezeka pang'ono. Pakulemba page yadzidzidzi, kumveka bwino ndiye chinthu chofunikira kwambiri chifukwa ogwira ntchito ayenera kumvetsetsa komwe kuli, kuchitapo kanthu, ndi changu mu uthenga umodzi.

Mabungwe apadziko lonse nthawi zambiri amagwiritsa ntchito lingaliro la Speech Transmission Index kuti aone momwe uthenga umamvekera bwino pamene pali phokoso ndi ma reverberation. Mwachidule, dongosololi liyenera kusunga makonsonanti ndi zizindikiro za nthawi, osati kungopanga mawu okweza. Wokamba nkhani wolemera wokhala ndi yankho loyera lapakati amatha kuchita bwino kuposa wokamba nkhani wokweza koma wosokoneza, makamaka pamene uthengawo uli ndi mayina a madera, malangizo, kapena malangizo othawa.

Mapangidwe a audio omwe amafanana ndi awa:

• Kutulutsa mawu kwambiri kungapangitse kuti anthu azitha kulankhula, koma kumawonjezeranso chiopsezo cha kutopa ndi kutopa kwa omvera.
• Kufalikira kolimba kungathandize kuti zinthu zizimveka bwino m'dera lomwe mukufuna, koma kumafuna kukonzekera bwino.
• Kusokoneza pang'ono nthawi zambiri kumathandizira kumvetsetsa bwino mawu kuposa kupeza mphamvu yochepa.
• Kulinganiza mosamala nthawi zambiri kumapereka zotsatira zabwino kuposa kuwonjezera njira ina yowonjezerera mawu.

Pa migodi yokhala ndi phokoso losinthasintha kumbuyo, njira yosinthira ndiyo yabwino kwambiri. Pa nthawi ya kuphulika, kuphwanya, kapena ntchito zolowetsa, makina osinthira angafunike ma profiles okonzedwa kale kuti azitha kumveka bwino popanda kudula. Imeneyo ndi ntchito yokonza makina, osati kungogula mawu okha.

Kuyika, kukonza, ndi ndalama zogwirira ntchito za migodi

Kuyika makina ndi chinthu chodalirika, osati chowonjezera. Malo opangira migodi amachititsa kugwedezeka kuchokera ku magalimoto, ma conveyor, ndi kayendedwe ka kapangidwe kake, kotero bulaketi ya sipika iyenera kukana kumasuka pakapita nthawi. Ngati ngodya yolunjika isintha ndi madigiri ochepa okha, malo ophimba amatha kusuntha mokwanira kuti apange madera akufa. Ichi ndichifukwa chake ma washer oletsa kugwedezeka, zomangira zosagwira dzimbiri, ndi mabulaketi otsekeka ndizofunikira kutchula momveka bwino.

Kukonzekera kukonza kuyeneranso kuikidwa mu dongosolo kuyambira tsiku loyamba. Magulu a malo nthawi zambiri amafuna ma terminal blocks omwe amapezeka mosavuta, ma gasket osinthika, ndi zida zokhazikika. Ngati kukonza kumafuna kuzimitsa malo onse kapena zida zapadera zomwe sizikupezeka pamalopo, ndalama zogulira nthawi yopuma zimakwera mwachangu. M'mapulojekiti ambiri, sipika yotsika mtengo kwambiri imakhala yokwera mtengo kwambiri ikayikidwa komanso zaka ziwiri zogwirira ntchito.

Kuchokera pa mtengo, kuganiza za moyo wonse n'kofunika kwambiri kuposa mtengo wa unit. Mapulojekiti a mafakitale nthawi zambiri amagula pamtengo wonse wa umwini, womwe umaphatikizapo antchito, kuchuluka kwa nthawi yosinthira, mawaya, kuyesa, ndi kusokoneza kupanga. Mu migodi, komwe kupeza zinthu kungakhale kovuta komanso mawindo a nyengo ndi ochepa, cholankhulira cholimba cha PA chingachepetse maulendo okonza ndi kuchepetsa chiopsezo chogwira ntchito ngakhale mtengo wake woyambirira uli wokwera.

Momwe mungayesere wokamba nkhani wolemera musanagule

Njira yabwino kwambiri yogulira zinthu ndi yokonzedwa bwino komanso yochokera ku umboni. M'malo mofunsa kuti “Kodi ndi yokweza mokwanira?”, wogula ayenera kufunsa ngati cholankhuliracho chili choyenera phokoso la tsambalo, malo, ndi kayendedwe kadzidzidzi. Izi zikutanthauza kuwunikanso mapepala a deta, malipoti oyesera, zojambula zomangirira, ndi ma diagram a dongosolo pamodzi.

1. Yesani phokoso la mlengalenga pamalo ndi nthawi zomwe zimayimira.
2. Fotokozani madera omwe amafunika kufotokozedwa mwachindunji.
