Momwe Mungasamalire Cholankhulira Cha Mafakitale ndi Cholankhulira Cha Fakitale cha Dongosolo La Cholankhulira

• Kukonza kuyenera kukhala patsogolo kumvetsetsa, osati kuchuluka kokha, chifukwa mauthenga adzidzidzi ndi opanga ayenera kumvedwa pansi pa phokoso lalikulu.
• Kulephera kwa ma sipika a mafakitale nthawi zambiri kumabwera chifukwa cha kupsinjika kwa chilengedwe: chinyezi, kupopera mchere, fumbi, kugwedezeka, ndi kusintha kwa kutentha.
• Ndondomeko yabwino yosamalira imaphatikizapo kuyeretsa, kuyang'anira mphamvu ya magetsi, kuyang'anira chingwe, kuyesa mawu, ndi kukonzekera kusintha pogwiritsa ntchito log.
• Gwiritsani ntchito miyezo monga IEC 60268-16 poyesa kufalitsa mawu ndi IEC 60529 potsimikizira chitetezo cha kulowa.
• Pa malo a polojekiti, kukonza kumakhala kosavuta ngati dongosololi lalembedwa ndi zone, amplifier, mtundu wa sipika, ndi nthawi yogwirira ntchito.

Kusamalira zokuzira mawu zamafakitale n'kofunika chifukwa kumveka bwino kwa mawu nthawi zambiri kumakhala cholinga chenicheni cha ntchito, osati kutulutsa mawu osaphika. IEC 60268-16 imagwiritsidwa ntchito kwambiri poyesa ubwino wa mawu otumizidwa, pomwe IEC 60529 imatanthauzira milingo yotetezera malo monga IP65 ndi IP66 kuti asagwere fumbi ndi madzi; ziwerengerozi zimathandiza kufotokoza chifukwa chake mayunitsi ena a zokamba nkhani zamafakitale amakhalabe panja kwa zaka zambiri pomwe ena amalephera msanga. Pa malo opangira phokoso, ngakhale makina amphamvu a zokamba mawu amatha kugwira ntchito molakwika ngati ma grille atseka, kutseka ukalamba, kapena zokonzera za amplifier zikuchepa. Ngati tsamba lanu likugwiritsa ntchitozida zolumikizirana zamafakitale, zipangizo zoteteza nyengokapenazida za m'dera loopsa, mfundo yofanana yosamalira imagwiranso ntchito: kuteteza malo otchingira, kutsimikizira njira ya chizindikiro, ndikulemba zowunikira zilizonse.

Zimene kukonza zokuzira mawu m'mafakitale kumateteza kwenikweni mu makina okuzira mawu

Kusamalira zokuzira mawu zamafakitale kumateteza zinthu zitatu: kumveka bwino, nthawi yogwira ntchito, ndi kutsatira malamulo.

M'machitidwe, magulu ambiri a mafakitale amaona vuto pokhapokha mauthenga atakhala ovuta kumvetsetsa, koma panthawiyo chifukwa chake nthawi zambiri chimakhala chochuluka. Kuchuluka kwa fumbi kumachepetsa kutulutsa kwa mawu, ma terminals owonongeka amawonjezera kukana, ndipo kulowa kwa madzi kumasintha khalidwe la dalaivala. Sipika ya fakitale yomwe imawoneka bwino imatha kutaya kumveka bwino ngati diaphragm yatopa kapena transformer ikutentha kwambiri.

Pa malo opangira mafakitale, cholinga chokonzera chiyenera kuyesedwa. Kutumiza mawu nthawi zambiri kumayesedwa ndi njira zolondola, ndipo IEC 60268-16 imapereka njira yokhazikika yowunikira chizindikiro cha kutumiza mawu. Izi ndizofunikira chifukwa uthenga wokweza womwe wasokonekera ungakhale wothandiza pang'ono kuposa uthenga wodekha koma womveka bwino. Pakulankhulana mwadzidzidzi, kumveka bwino kumasunga nthawi, kumachepetsa chisokonezo, komanso kumachepetsa mwayi wosokoneza ogwira ntchito panthawi yochoka.

Palinso mtengo wogulira zinthu. Malinga ndi malangizo a US OSHA, mauthenga adzidzidzi ayenera kukhala odalirika mokwanira kuti athandize anthu othawa kwawo komanso kukonzekera bwino malo ogwirira ntchito, ndichifukwa chake zolemba zowunikira ndi macheke ogwira ntchito sizosankha m'malo olamulidwa. Kwa magulu a mainjiniya, kukonza ndi gawo lowongolera zoopsa, osati ntchito yokongoletsa.

Njira zomwe muyenera kuyembekezera kuti mawu okweza mawu a mafakitale ndi okamba nkhani a fakitale alephereke

Mavuto ambiri okhudza ma sipika a mafakitale ndi odziwikiratu ngati chilengedwe chikudziwika.

Chinyezi chochuluka, kupopera mchere, fumbi, ndi kugwedezeka ndi zinthu zomwe zimadetsa nkhawa kwambiri poika ma speaker m'fakitale. Ngati malowo ali pafupi ndi mizere yotsukira, madoko a m'nyanja, malo okonzera chakudya, kapena malo otulutsira katundu panja, malo olumikizirana ndi ma connector amakhala malo oyamba ofooka. Unyolo wamba wolephera umayamba ndi kuwonongeka kwa chisindikizo, kenako kulowa kwa chinyezi, kenako kusungunuka, kenako phokoso losakhazikika kapena kulephera kwathunthu kwa dalaivala.

Kugwedezeka ndi chinthu china chobisika. M'mafakitale opanga zinthu, kugwedezeka mobwerezabwereza kwa makina kumatha kumasula zomangira ndi zotchingira pakapita nthawi. Ichi ndichifukwa chake sipika ya fakitale yoyikidwa pa chimango chachitsulo iyenera kuyang'aniridwa kuti ione ngati pali mphamvu yolimba komanso kuti chingwecho chichepetse kupsinjika, makamaka pamene makina okweza mawu aikidwa pafupi ndi makina osindikizira, ma conveyor, kapena makina olemera.

Kusintha kwa kutentha nakonso n'kofunika. Zolankhulira zakunja ndi zakunja zimatha kukulirakulira ndikuchepa tsiku lililonse, pang'onopang'ono kufooketsa zisindikizo ndikupanga mipata yaying'ono yomwe imalola fumbi ndi chinyezi kulowa. Pazochitika zimenezo, yankho lolondola lokonza silikungoyeretsa; ndi kubwezeretsanso nthawi ndi nthawi umphumphu wa malo obisika ndikusintha ma gasket okalamba asanagwe.

Momwe mungasungire makina olankhulira mawu pang'onopang'ono

Kuyang'anira bwino nthawi zonse ndiyo njira yabwino kwambiri yosungira netiweki ya ma loudspeaker m'mafakitale kukhala yodalirika.

1. Yambani ndi kuyang'ana m'maso malo ozungulira, ma grille, mabracket, ndi ma cable glands.
2. Yang'anani ngati pali ming'alu, dzimbiri, zizindikiro za madzi, kuwonongeka kwa UV, ndi zida zomwe zikusowa.
3. Tsimikizirani momwe amplifier ilili, zilembo za zone, ndi zizindikiro zilizonse zolakwika pa chowongolera.
4. Sewerani chilengezo cha mayeso ndipo mvetserani ngati pali kusokonekera, kugwedezeka, kapena kufalikira kosagwirizana.
5. Yesani zotsatira m'malo ofunikira kwambiri ndipo yerekezerani ndi ziwerengero zoyambira.
6. Lembani tsiku loyendera, malo omwe akhudzidwa, ndi njira zowongolera.

Magulu abwino kwambiri okonza zinthu nthawi zonse amagwira ntchito motsatira chigawo. Izi zikutanthauza kuti cholankhulira chilichonse cha mafakitale chimagwirizana ndi malo, cholinga, ndi magwiridwe antchito oyenera. Mwachitsanzo, cholankhulira cha pansi chopangira zinthu chingakhale chovomerezeka pamlingo wosiyana wa phokoso kuposa cholankhulira cha m'mbali chifukwa phokoso lakumbuyo silili lofanana pamalo onse. Njira imeneyi yochokera ku chigawo imapangitsa kuti mavuto azitha msanga komanso imathandiza kupewa kusintha kosafunikira.

Kuyeretsa kuyenera kusamalidwa. Grille ya sipika ya fakitale iyenera kutsukidwa pogwiritsa ntchito njira zogwirizana ndi zinthu zomangira komanso IP rating. Madzi amphamvu sayenera kugwiritsidwa ntchito pokhapokha ngati kapangidwe ka chinthucho kakugwirizana ndi izi. M'malo mwake, gwiritsani ntchito njira zotsukira zosaopsa zomwe zimachotsa fumbi, mafuta oundana, ndi zotsalira za mchere popanda kukakamiza zodetsa kulowa m'nyumba.

Malinga ndiISO 7240-16, makina ochenjeza mawu akuyembekezeka kuthandizira kulankhulana kodalirika kwadzidzidzi, ndipo chiyembekezo chimenecho chimakhudza momwe kukonza kumakonzedwera. Ngati makina olankhulira mawu akugwiritsidwa ntchito pochotsa anthu kapena zidziwitso za fakitale, kuchuluka kwa mayeso kuyenera kukhala kocheperako kuposa momwe amagwirira ntchito nthawi zonse.

Miyezo yofunika kwambiri pa chisamaliro cha ma speaker a mafakitale ndi ma speaker a fakitale

Miyezo imapatsa magulu okonza zinthu chilankhulo chofanana chowunikira ndi kuvomereza.

IEC 60529 imatanthauzira madigiri a chitetezo chomwe chimaperekedwa ndi ma enclosure, kuphatikizapo ma rating wamba monga IP65 ndi IP66. Pa sipika ya fakitale yomwe imayikidwa m'malo afumbi kapena onyowa, ma rating amenewo si kungolemba kabukhu kokha; ndi muyezo wokonzera. Ngati madzi kapena fumbi likulowa m' enclosure, chipangizochi chingapangebe mawu, koma sichikugwira ntchito bwino.

IEC 60268-16 ndi yofunika chifukwa imafotokoza za ubwino wotumizira mawu. Pa ma paging a mafakitale, malangizo adzidzidzi, ndi zilengezo za alamu, kumveka bwino ndiye KPI yeniyeni. Dongosolo lokweza koma losamveka bwino lingachedwetse kutuluka kapena kuyambitsa malangizo osowa, makamaka m'malo aphokoso komwe phokoso lakumbuyo lingapitirire 85 dB m'malo ena malinga ndi njira zosungira kumva za OSHA.

Pakukhazikitsa ndi kusunga zikalata, magulu ambiri amadaliranso zolemba zoyeserera ndi njira zolandirira malo. Mwachidule, izi zikutanthauza kulemba mtundu wa sipika, mphamvu yolumikizira, malo ophimbira, kutalika kwa malo oikira, ndi zotsatira za mayeso. Zolemba zimenezo ndi zomwe zimapangitsa kuti kukonza pambuyo pake kukhale kogwira mtima.

Posankha zinthu, zimathandiza kuyerekeza magulu a zida pa kulimba ndi kugwirira ntchito bwino. Ngati tsamba lanu likukula, mungafunike kuphatikizazipangizo zolumikizirana za analogi, Zipangizo zochokera ku IPndimagawo olumikizirana mwadzidzidziMfundo yomweyi imagwiranso ntchito pokonza sipika: khazikitsani muyezo momwe zingathekere, koma lembani komwe mitundu ya zida zimasiyana.

Momwe mungathetsere mavuto a ma loudspeaker a mafakitale asanayambe kuzimitsidwa

Njira yachangu yothetsera vuto la makina olankhulira ndikupeza ngati vutolo ndi lamagetsi, la mawu, kapena la chilengedwe.

Ngati sipika ili chete, yang'anani kaye njira ya amplifier, kusinthasintha kwa mzere, ndi fuse ya zone. Ngati kutulutsa kuli kofooka koma kulipo, yang'anani matampu a transformer, kukana kwa chingwe, ndi kuwonongeka komwe kungachitike chifukwa cha madzi. Ngati phokoso lasokonekera, vuto likhoza kukhala dalaivala wowonongeka, kudula kwa amplifier, kapena grille yotayirira yomwe imayambitsa kumveka bwino.

Njira yosavuta yogwiritsira ntchito ndi kuyerekeza sipika imodzi yokayikiridwa ya fakitale ndi chipangizo chodziwika bwino chomwe chili pamalo omwewo. Ngati vuto likutsatira sipika, vuto ndi lapafupi. Ngati vuto likukhalabe pamalowo, mawaya kapena amplifier mwina ndiye chifukwa chachikulu. Kuyerekeza kumodzi kumeneku kungapulumutse maola ambiri mu netiweki ya sipika yamafakitale yokhala ndi malo ambiri.

Magulu okonza ayeneranso kuyang'ana ngati akuyendetsa mopitirira muyeso. Mu makina a 100 V, makonda olakwika a tap amatha kudzaza amplifier ndikupanga kusokonekera nthawi yayitali asanayambe kulephera kugwira ntchito bwino. Chizindikirocho chingawoneke ngati sipika yoyipa, koma vuto lenileni nthawi zambiri limakhala kusintha kwa kapangidwe ka makina pambuyo pokulitsa kapena kukonzanso malo.

Ngati zolephera zikubwerezabwereza m'dera lomwelo, yang'anani zomwe zimayambitsa chilengedwe. Cholankhulira cha padoko chodzaza chomwe chikuwonetsedwa ku spray, kugwedezeka kwa forklift, ndi kusintha kwa kutentha chidzalephera mosiyana ndi chipinda choyera chamkati. Kukonza koyenera kungakhale malo abwino obisala, bulaketi yosiyana yoyikira, kapena kusuntha m'malo mosintha mobwerezabwereza.

Kusankha nthawi yokonza netiweki ya sipika ya fakitale

Nthawi zosamalira ziyenera kusonyeza kuopsa kwa malo, osati kungosangalala ndi kalendala yokha.

Chomera choyera chamkati nthawi zambiri chimatha kugwira ntchito pakatha kotala, pomwe malo akunja kapena otsukira angafunike kuyang'aniridwa mwezi uliwonse. Malo oopsa kapena adzidzidzi ayenera kuyang'aniridwa pafupipafupi chifukwa mtengo wake ndi wokwera. Ngati makina olankhulira mawu amathandizira ma alamu, kutuluka, kapena kulengeza kofunikira kwambiri, chigwiritseni ntchito ngati zida zotetezera moyo osati zida wamba za AV.

Pa chitsanzo chokonzekera chothandiza, malo ambiri amafakitale amagwiritsa ntchito ndondomeko ya magawo atatu:

• Kufufuza mwezi uliwonse malo omwe ali panja, onyowa, afumbi, kapena ogwedezeka kwambiri.
• Kufufuza kwa kotala lililonse kwa malo ogwirira ntchito ndi malo akunja okhala ndi zokutidwa.
• Utumiki wapachaka wa deep wowunikiranso mawu onse, kusintha zisindikizo, ndi kuwunika zikalata.

Njira imeneyi imathandizanso kukonza bajeti. M'malo mosintha mawu onse a mafakitale nthawi yoyamba kuwonongeka, mumasintha okhawo omwe akuwonetsa kuwonongeka koyezeka. Pakapita nthawi, zimenezo zimachepetsa kuthamanga kwa zinthu zomwe zilipo ndipo zimapewa nthawi yopuma yosayembekezereka.

Kwa magulu opeza zinthu zaukadaulo, sipika yabwino kwambiri yosamalitsa siili yokwera mtengo kwambiri. Ndi yomwe ili ndi mwayi woyika bwino, zida zosinthika, chithandizo chokhazikika cha zinthu, komanso kalasi yoteteza yolembedwa. Ichi ndichifukwa chake magulu ambiri a mapulojekiti amayerekezera osati kutulutsa mawu kokha komanso kuthekera kogwira ntchito, kupezeka kwa zinthu zina, komanso kapangidwe kake asanamalize makina olumikizira mawu.

Kodi zikalata zabwino bwanji pokonza zokuzira mawu zamafakitale

Zolemba zabwino zimasintha kukonza kukhala njira yobwerezabwereza.

Cholankhulira chilichonse cha mafakitale chiyenera kukhala ndi cholembedwa chomwe chimaphatikizapo malo, chitsanzo, mphamvu yopopera, tsiku loyika, kalasi yotetezera, zotsatira zomaliza za mayeso, ndi mbiri yakale yosintha. Ngati malowa ali ndi nyumba zingapo kapena madera opangira, onjezani chizindikiro cha mapu kapena chizindikiritso cha katundu. Izi zimapangitsa kuti kufufuza zolakwika kukhale kofulumira kwambiri pamene vuto la tsamba likuwonekera panthawi yosintha kusintha kapena kuchita masewera olimbitsa thupi mwadzidzidzi.

Zolemba zokonzera ziyeneranso kujambula njira yoyesera. Cholemba chomwe chimati "chayesedwa bwino" sichithandiza kwenikweni kuposa chomwe chimalemba zotsatira zoyezedwa, kusokonekera komwe kwawonedwa, ndi kumveka bwino malinga ndi madera. Deta ikagwirizana kwambiri, zimakhala zosavuta kuwona momwe zinthu zilili zowonongeka zisanawonekere.

Pa malo omwe ali ndi njira zosiyanasiyana zolumikizirana, njira yofanana yolembera ingagwiritsidwe ntchito m'magulu onse a zida. Mwachitsanzo, fakitale ikhoza kuyikamakina a intercom, mayunitsi adzidzidzi, ndi maukonde a ma speaker a fakitale pamodzi, kotero kaundula wa katundu ayenera kuwonetsa momwe gawo lililonse limathandizira pa kayendedwe kofanana ka mauthenga.

Malinga ndi malangizo a NIST pankhani yowunikira kutsata, zisankho zobwerezabwereza zosamalira zimadalira kuyeza kosalekeza komanso njira zolembedwa. Mfundo imeneyi imagwira ntchito mwachindunji poyesa mawu: ngati simuyesa mwanjira yomweyo nthawi iliyonse, simungathe kutsimikizira bwino kusintha kapena kuwonongeka.

Njira zabwino kwambiri zowonjezerera nthawi ya ma sipika a mafakitale

Machitidwe omwe amakhala nthawi yayitali ndi omwe amatetezedwa ku nkhawa zomwe zingapeweke.

Gwiritsani ntchito mlingo woyenera wa malo obisika, pewani kugwiritsa ntchito chingwe chocheperako, ndipo onetsetsani kuti sipika yayikidwa kuti madzi asamire pa grille kapena bracket. Sungani njira yolumikizirana yozungulira chipangizocho kuti akatswiri athe kuchiyang'ana popanda kuwononga nyumbayo. Ngati malowo amagwiritsa ntchito zotsukira pafupipafupi, onetsetsani kuti mankhwala oyeretsera akugwirizana ndi zinthu zobisikazo komanso kapangidwe ka gasket.

Zosankha ziwiri za kapangidwe kake zimapangitsa kuti kukonza kukhale kosavuta pakapita nthawi. Choyamba, gwiritsani ntchito zida zokhazikika zomwe zingatheke kuti kusintha kukhale kofulumira. Chachiwiri, sungani zida zosinthira kapena zida zofunika kwambiri m'malo omwe nthawi yogwira ntchito imakhala yokwera mtengo. M'mafakitale ambiri, vuto lalikulu kwambiri si sipika yokha; koma kuchedwa kubwezeretsa kulumikizana.

Ngati polojekiti yanu ikuphatikizapo malo ovuta akunja kapena olamulidwa, mungafunenso zipangizo zopangidwira nyengo kapena kugwiritsa ntchito mwadzidzidzi, mongamayankho a mafoni a mafakitalendi malo olumikizirana okhudzana nawo. Magulu amenewo nthawi zambiri amakhala ndi zinthu zofunika kwambiri zodalirika: kudalirika kwa malo obisika, kuthekera kogwira ntchito, komanso kupezeka kwa nthawi yayitali.
