Intengo Eqondile Yesipikha Sezimboni Isilinganiso se-IP Isandisi Sezimboni Uhlelo lwe-PA

• Isilinganiso se-IP sesipikha sezimboni sithinta ukuqina, hhayi nje ukuvimbela amanzi.
• Intengo yangempela incike ezingeni lomkhiqizo, izinto zokwakha, ukuvala, kanye nobubanzi besitifiketi.
• Ezitshalweni ezinomsindo, ukwakheka kohlelo lwe-PA kufanele kubeke phambili ukuqondakala kanye nokumbozwa, hhayi amandla kuphela.
• Ukuqhathaniswa kwezincazelo kulula uma uhlukanisa izimo zokusetshenziswa ngaphakathi, ngaphandle, kanye nendawo eyingozi.

Isilinganiso se-IP sesipikha sezimboni, isipikha sezimboni, kanye nentengo yesistimu ye-PA kuhlobene kakhulu ngoba isipikha esisinda egcekeni lefektri asinayo intengo efana neyunithi eyisisekelo yangaphakathi. Ngokusho kohlaka lwe-IEC IP Code, i-IP65 isho ukuvalwa kothuli futhi ivikelwe kumajethi amanzi, kuyilapho i-IP66 ithuthukisa ukuvikelwa kumajethi amanzi anamandla; lowo mehluko uvame ukushintsha ukwakheka kwe-gasket, izindlala zekhebula, kanye nezindleko zomsebenzi njengoba kunjalo nendawo ebiyelwe ngokwayo. Kubathengi bephrojekthi, umbuzo obalulekile awugcini nje ngokuthi "kubiza malini," kodwa "yimuphi umsindo wokumbozwa, ukuthembeka, kanye nesitifiketi engikudingayo ngempela?" Uma isayithi lakho liphinde lihlanganise izexwayiso eziphuthumayo noma izimemezelo zenqubo, ungaqhathanisa izinketho zesistimu ezibanzi kuikhasi lesipikha sezimboni, iIkhasi lesistimu ye-PA, kanyeikhasi lesipikha sangaphandleukuqonda ukuthi ikilasi le-enclosure lishintsha kanjani i-bill yezinto zokwakha.

Lokho okushiwo yisilinganiso se-IP sesipikha sezimboni ohlelweni lwe-PA

Isilinganiso se-IP siyinkomba yokuvikela, hhayi amaphuzu ekhwalithi yomsindo.

Ekuthengeni izipikha zezimboni, abathengi abaningi baqala ngombono ongalungile: ukuthi ikhodi ye-IP ephezulu isho ngokuzenzakalelayo uhlelo lwe-PA olungcono. Empeleni, ikhodi ye-IP ikutshela ukuthi indlu imelana kahle kangakanani nezinto eziqinile kanye nokungena kwamanzi. Ayikutsheli ukuthi isipikha singanqoba yini umsindo we-ambient ongu-85 dB, ukuthi inkulumo ihlala iqondakala yini uma ikude, noma ukuthi i-mounting bracket ingasinda yini ekudlidlizeni. Uhlelo lwe-IEC lusebenzisa izinombolo ezimbili: inombolo yokuqala ichaza ukuvikelwa okuqinile, kanti inombolo yesibili ichaza ukuvikelwa koketshezi. Lokho kusho ukuthi isipikha sezimboni se-IP66 senzelwe ukuhlanza kanzima noma ukuvezwa ngaphandle kuneyunithi ye-IP54, kodwa ukwakheka kwe-acoustic kusamele kuqinisekiswe ngokwehlukile.

Kumaqembu okuthenga, lokhu kubalulekile ngoba isilinganiso se-IP sithinta ingozi yomjikelezo wokuphila. Isipikha esise-chemical loading bay, ipulatifomu yesitimela, noma igceke lokucubungula singase singasebenzi kahle kusenesikhathi uma izivalo, izikhonkwane, noma ukufakwa kwekhebula kungacaciswanga kahle. Kulawo maphrojekthi, abathengi bavame ukukhokhela hhayi kuphela isipikha esikhulu kodwa futhi nomkhawulo wobunjiniyela osigcina sisebenziseka ngemva kokuchayeka kaningi emvuleni, othulini, ekudlidlizeni, nasekujikelezeni kokushisa.

Indlela okwakhiwa ngayo amanani aqondile ezikhulwini zezimboni

Intengo yesipikha sezimboni ngokuvamile iyinqwaba yezindleko zezingxenye kunokuba ibe yintengo yesitikha esisodwa.

Isilinganiso esiqondile sivame ukukhombisa izendlalelo ezinhlanu: ihadiwe ye-acoustic, i-enclosure kanye ne-sealing, ukufakwa kanye nokufakwa, imibhalo yokuthobela imithetho, kanye nenani le-oda. Isipikha sophahla sangaphakathi esingu-10 W kanye nesipikha sophondo esingu-60 W IP66 singase sibukeke sifana kukhathalogi, kodwa isakhiwo sazo sezindleko asifani. Uhlobo lophondo lungadinga indlu ebanzi, izibambo ezingagqwali, i-polymer engamelana ne-UV, kanye nomzila wekhebula ovalwe yisimo sezulu. Lezo zengezo ziphakamisa izindleko zezinto, kodwa futhi zinciphisa izingcingo zokulungisa kanye nemvamisa yokushintsha.

Kumaphrojekthi angempela, isicelo sentengo eqondile siwusizo kakhulu lapho umthengi ecacisa umsindo ozungezile, ibanga lokufaka, ukuchayeka esimweni sezulu, nokuthi ngabe iyunithi ingeyokufaka ama-page, ukuthutha, noma izimemezelo zenqubo. Yingakho isandisi-zwi esifanayo sezimboni singathola izingcaphuno ezihluke kakhulu kusuka endaweni eyodwa kuya kwenye.

Amazinga okulinganisa i-IP yesipikha sezimboni kanye nalokho abathengi okufanele bakulindele

Amazinga e-IP ahlukene ahambisana nezindawo zokusebenza ezahlukene.

Ngokukhetha uhlelo lwe-PA lwezimboni, i-IP54 ivame ukwamukeleka ezindaweni ezivikelekile zangaphakathi, kuyilapho i-IP65 ne-IP66 zivame kakhulu ezindaweni zangaphandle noma zokuhlanza. Indawo evalekile ye-IP65 ayivali uthuli futhi ivikelwe ezindizeni zamanzi; i-IP66 ayivali uthuli futhi ivikelwe ezindizeni zamanzi ezinamandla, ngokusho kweKhodi ye-IP ye-IEC. Uma indawo ibhekene nokuhlanza njalo, imvula evunguzayo, noma ukuhlanzwa kwamapayipi, i-IP66 ivame ukuba yindawo ephephile. Uma indawo ingaphansi kophahla noma ngaphakathi kwegumbi lesitshalo elivikelwe, i-IP54 ingaba yanele futhi inganciphisa izindleko.

Intengo kufanele futhi ibonise ukucindezeleka kwemvelo. Isipikha esivezwe ku-UV, inkungu kasawoti, kanye nokushintshashintsha kwezinga lokushisa sidinga okungaphezu kwe-gasket engangeni manzi. Kungadinga ama-polymer azinzile ku-UV, izikulufo ezingagqwali, kanye nezindlala zekhebula ezigcina isilinganiso se-IP ngemva kokufakwa. Yingakho intengo eqondile yezipikha zezimboni ivame ukuba nemba kakhulu kuphela ngemva kokuba uhlu lokuhlola indawo seluqediwe.

Ukucindezela komsindo, ukumbozwa, kanye nezindleko zangempela zokucaca

Ukuzwakala kahle kwenkulumo kuvame ukuba yigugu kakhulu kunevolumu ephezulu.

Esitshalweni esinomsindo, uhlelo lwe-PA luhlulelwa ngokuthi abasebenzi bayawuqonda yini umyalezo ngesikhathi esisodwa. I-OSHA iphawula ukuthi ukuvezwa ku-85 dBA noma ngaphezulu kwesilinganiso sesikhathi samahora angu-8 kudinga uhlelo lokulondolozwa kokuzwa, oluqokomisa ukuthi zingaki izindawo zezimboni ezingaba nomsindo omkhulu. Kulowo mongo, isikhulumi kumele sinikeze umfutho womsindo owanele ngaphezu komsindo wangemuva ukuze sigcine inkulumo iqondakala. Isikhulumi se-horn esingu-30 W singase sanele umzila, kuyilapho isakhiwo se-60 W noma izikhulumi eziningi ezisatshalaliswe singadingeka egcekeni elinemishini esindayo.

Iphutha lokuthenga elingokoqobo ukuqhathanisa ama-watts kuphela. I-Wattage umthamo wokufaka kagesi, akuyona indlela eqondile yokulinganisa ukuzwakala. Isipikha esiqondiswe kahle esingu-30 W singenza kahle kakhulu kuneyunithi engu-100 W engaqondiswanga kahle uma ukusabalala kwe-horn kufana nendawo. Ngakho-ke abathengi kufanele bacele i-geometry yokumbozwa, isiqondiso sokuphakama kokukhweza, kanye nokucaca kwezwi okulindelekile endaweni eqondiwe.

Njengereferensi, umkhawulo we-OSHA ongu-85 dBA awuyona inhloso yokuklama izipikha, kodwa uyisikhumbuzo esiwusizo sokuthi izinhlelo zomsindo zezimboni kumele zincintisane namazinga omsindo anganciphisa ukucaca kwenkulumo ngokushesha.

Izinto zokwakha, ukufakwa, kanye nokugcinwa kwamanani ohlelweni lwe-PA lwezimboni

Umklamo wemishini uvame ukunquma izindleko zesikhathi eside ngaphezu komshayeli wesipikha uqobo.

Ukuhlanganiswa kwesikhulumi sezimboni kuyahluleka ensimini ngenxa yokugqwala, ukukhululeka kokudlidliza, ukungena kwekhebula, kanye nokuwohloka kwe-UV. Ibhulakhethi yensimbi engagqwali ingabiza kakhulu uma uyithenga, kodwa ezindaweni ezisogwini noma zamakhemikhali inganciphisa imvamisa yokushintsha futhi igweme ukulahlekelwa isikhathi sokusebenza. Ngokufanayo, izindlala zekhebula ezivalekile kanye nokukhululeka kokucindezeleka okufanele kusiza ukugcina isilinganiso se-IP ngemuva kokufakwa. Uma isikhulumi sifakwe esakhiweni esidlidlizayo, ukuqina kwebhulakhethi kanye nezinga le-fastener kuba yingxenye yentengo iyonke yesistimu.

Ukufinyelela ekulungiseni nakho kubalulekile. Iphrojekthi enokuhlolwa okuvamile noma ukuprakthiza i-alamu izuza ngomklamo ovumela ukuhlolwa okusheshayo ngaphandle kokudiliza yonke iyunithi. Ezindaweni ezilawulwayo, lokho kunganciphisa abasebenzi benkonzo futhi kuvimbele ukuhlolwa kokuhambisana nomthetho ekubeni umthwalo wokusebenza ophindaphindayo.

• Hlola ukuthi indawo ebiyelwe isebenzisa yini izinto ezingamelani ne-UV ukuze ibonakale ngaphandle.
• Qinisekisa ukuthi okufakiwe kwekhebula kugcina isilinganiso se-IP esishiwo ngemuva kokufakwa kwensimu.
• Hlanganisa izinto ezisetshenziswa ebhulakini nendawo ezungezile: i-galvanized, i-aluminium, noma insimbi engagqwali.
• Qinisekisa ukuthi izingxenye ezithathelwa indawo ziyatholakala yini kuma-driver, ama-gasket, kanye nama-mounts.

Izindinganiso kanye nokuhambisana nomthetho okuthinta amanani ezikhulumi zezimboni

Ukuthobela imithetho kungashintsha kokubili ukuzethemba kwentengo kanye nokuthengwa kwempahla.

Isilinganiso se-IP ngokwaso sichazwa uhlaka lwe-IEC IP Code, futhi abathengi kufanele bacele isilinganiso esiqondile kunesimangalo esingacacile njengokuthi “asivimbeli manzi.” Ohlangothini oluvaliwe lwesinqumo, isiqondiso samazwe ngamazwe sicacile: i-IP65 ne-IP66 zisho amazinga ahlukene okuchayeka emanzini, ngakho-ke akufanele kufakwe okunye esikhundleni senye ngesikhathi sekhotheshini. Uma iphrojekthi idinga ukusetshenziswa endaweni eyingozi, ububanzi bamanani buyanda kakhulu ngoba imishini evikelwe ukuqhuma kumele ihlangabezane nezidingo ezengeziwe zesitifiketi ngale kokuvikela isimo sezulu okuvamile.

Kumaphrojekthi aphuthumayo noma esixwayiso somphakathi, imishini yomsindo ingadinga ukuhambisana nemithetho yokuphepha yendawo kanye nokuphuma. Uma i-loudspeaker iyingxenye yenethiwekhi yesaziso ebanzi, ukuhambisana nama-amplifier, abalawuli, kanye nokufakwayo okubangela umsindo kubaluleke kakhulu njengomzimba we-loudspeaker. Yingakho abathengi abaningi bezimboni bebukeza imindeni yemikhiqizo kuqala, njengeikhasi lesipikha se-horn, iikhasi lesipikha elingangenisi manzi, kanyeikhasi lesistimu yesimemezelo esiphuthumayo, ngaphambi kokucela ikhotheshini eqondile.

Indlela yokuqhathanisa izingcaphuno zesipikha sezimboni ngaphandle kokwenza ukuqhathanisa intengo okungamanga

Isilinganiso esishibhile ngokuvamile asiphelele.

Uma abathengi beqhathanisa izingcaphuno zesilinganiso se-IP yesipikha sezimboni, iphutha elivame kakhulu ukuqhathanisa iyunithi engenalutho nephakheji eklanywe ngokugcwele. Omunye umhlinzeki angafaka i-horn enclosure, i-stainless bracket, kanye nokufakwa kwekhebula elivaliwe, kanti omunye ubala umzimba wesipikha kuphela. Umphumela ubukeka njengentengo ephansi, kodwa izindleko zokufaka nokulungisa zifihliwe. Ukuze ugweme lokhu, cela wonke umthengisi ukuthi acaphune ububanzi obufanayo, izinga elifanayo le-IP, isilinganiso samandla esifanayo, kanye nendlela efanayo yokufaka.

1. Chaza indawo ezungezile: ngaphakathi, ngaphandle, endaweni yokugeza, esogwini, noma enothuli.
2. Cacisa isilinganiso se-IP esidingekayo nokuthi ngabe ukuchayeka kuqondile noma kuvikelwe.
3. Shano usayizi wendawo okuqondiwe kuyo, ukuphakama kokuyifaka, kanye nezinga lomsindo wangemuva.
4. Cela isilinganiso samandla, i-impedance, kanye nokuqhathaniswa kwe-amplifier okunconyiwe.
5. Cela ikhotheshini ephelele ehlanganisa i-bracket, ama-glands, kanye nemibhalo.

Lolu hlu lokuhlola lukusiza ukuthi uqhathanise amanani aqondile ngokwesisekelo sama-apula nama-apula futhi lunciphisa ingozi yokuthenga iyunithi ebukeka ingabizi kodwa yehluleka emkhakheni.

Ungakhetha nini isilinganiso se-IP esiphezulu noma ngabe intengo eqondile iphakeme

Ukuvikelwa okuphezulu kuyakufanelekela intengo ephezulu uma isikhathi sokuphumula sibiza kakhulu.

Uma indawo yakho inemvula evame ukuna, ukukhukhuleka kwamanzi, noma uthuli oluhamba emoyeni, ukukhetha i-IP66 esikhundleni se-IP54 kungaba yisinqumo esishibhile eminyakeni emibili kuya kwemihlanu yokuphila, ikakhulukazi lapho ukufinyelela kunzima noma ukuvalwa kubiza kakhulu. Izindleko ezengeziwe zangaphambilini zingase zincishiswe ngokufakwa kwezindawo ezintsha ezimbalwa, ukuvakashelwa kwezinsizakalo ezimbalwa, kanye nengozi yokwehluleka kokuxhumana ephansi ngesikhathi sama-alamu noma izinguquko zeshifti. Ezindaweni eziningi zezimboni, i-loudspeaker iyinto encane ebhajethini yephrojekthi kodwa incike kakhulu ekuxhumaneni ngokuphepha.

Umthetho osebenzayo ulula: uma ukwehluleka kwesipika kungabambezela ukuphuma, ukuxhumanisa inqubo, noma ukubhalwa kwekhasi okuphuthumayo, khokha izinga eliphezulu lokuvikela. Uma iyunithi ivikelekile ngokuphelele futhi kulula ukuyinakekela, isigaba se-IP esiphansi singase sanele. Ukukhetha okulungile yilowo ohambisana nengozi, hhayi lowo omane unciphise i-invoyisi yokuqala.

Izimpawu zamanani eziqondile abathengi okufanele bazicele ohlelweni lwe-PA yezimboni

Isilinganiso esihle kakhulu yilesi esisusa ukungaqiniseki.

Ngaphambi kokuthi ucele intengo, chaza indlela eqondile yokusebenzisa, ngoba intengo yesipikha sezimboni iyashintsha ngayo yonke i-variable oyishiya ingacacile. Ikhotheshini eqondile kufanele isho isilinganiso se-IP, amandla alinganisiwe, impedance ejwayelekile, izinto ezivalekile, uhlobo lwebracket, ububanzi bokushisa bokusebenza, kanye nanoma yimaphi amanothi okuhambisana nomthetho. Uma uhlelo lokusebenza luyi-paging yangaphandle, cela imininingwane ye-UV kanye nokumelana nokugqwala. Uma kungukuxhumana okuphuthumayo, buza ukuthi iyunithi iziphatha kanjani ngaphansi komsebenzi oqhubekayo.

Ukuze kube lula ukukhetha, sebenzisa izendlalelo ezintathu zezinqumo: indawo kuqala, imfuneko ye-acoustic yesibili, kanye nendlela yokufaka yesithathu. Lolo chungechunge luvimbela amaqembu okuthenga ukuthi angathengi kakhulu kuhadiwe ngenkathi lusavikela ukuthembeka.

• Indawo: eyomile ngaphakathi endlini, evezwe ngaphandle, ehlanza ngamanzi, noma egqwalisayo.
• Ama-acoustics: ukumbozwa okudingekayo, ibanga, kanye nokuncintisana komsindo.
• Ukufakwa: ukufakwa odongeni, ensikeni, ophahleni, noma ozimele bomshini.

Ezinhlanganweni ezihlela ukuqaliswa okukhulu, kuvame ukusebenza kahle ukuvumelanisa ukukhethwa kwesipikha nokwakhiwa okubanzi kokuxhumana kwesayithi. Amakhasi e-izixazululo zokuxhumana zezimbonifuthiimikhiqizokungasiza amaqembu ukuthi ahlele ukukhethwa kwezipikha kulo lonke uhlelo lokuxhumana.

Imibuzo Evame Ukubuzwa

Kusho ukuthini isilinganiso se-IP sesipikha sezimboni?

Kusho ukuthi indawo ebiyelwe inezinga elichaziwe lokuvikelwa ekungeneni kothuli namanzi ngaphansi kweKhodi ye-IP ye-IEC. Ayikalingi ikhwalithi yomsindo noma umsindo ngokwawo.

Ingabe i-IP65 yanele isikhulumi sezimboni sangaphandle?

Ngokuvamile yebo uma isetshenziswa ngaphandle, ngoba i-IP65 ayivali uthuli futhi imelana nama-jets amanzi. Uma indawo ibhekene nokufuthwa kwamanzi okunamandla noma ukuhlanza okukhulu, i-IP66 ivame ukuba iphephile.

Kungani isandisi-zwi esingangenisi isimo sezulu sibiza kakhulu?

Izindleko ziyakhuphuka ngenxa yokuvalwa, ihadiwe engagqwali, izinto eziqinile ze-UV, kanye nokuhlolwa okwengeziwe. Ihadiwe yokufaka kanye nemibhalo nakho kunganezela entengweni eqondile.

Ingabe kufanele ngithenge nge-wattage noma nge-coverage?

Ukusabalala kanye nokuzwakala kahle kufanele kuze kuqala. I-Wattage ibalulekile, kodwa isipikha esibekwe kahle esine-watt ephansi singenza kahle kakhulu kuneyunithi ene-watt ephezulu endaweni engafanele.

Yiluphi ulwazi okufanele ngiluthumele ukuze ngithole ikhotheshini enembile?

Thumela uhlobo lwendawo, imfuneko yesilinganiso se-IP, isilinganiso samandla, indlela yokufaka, usayizi wendawo, izinga lomsindo ozungezile, nokuthi ngabe uhlelo lungolwe-paging, i-alamu, noma izimemezelo ezijwayelekile.

Ingabe izilinganiso ze-IP eziphakeme zihlala zisho inani elingcono?

Akunjalo ngaso sonke isikhathi. Izilinganiso ze-IP eziphakeme zifanele izindleko ezengeziwe uma ukuchayeka esimweni sezulu, uthuli, noma ingozi yokuwa ibalulekile. Ezindaweni ezivikelekile, isilinganiso esiphansi singaba ngcono kakhulu.

Ngingakugwema kanjani ukuqhathanisa izingcaphuno ezingaphelele?

Cela wonke umhlinzeki ukuthi asho isilinganiso esifanayo: umzimba wesipikha, ibhulakhethi, izingxenye zokungena kwekhebula, isilinganiso samandla, isilinganiso se-IP, kanye nemibhalo. Bese uqhathanisa izindleko zomjikelezo wokuphila, hhayi nje i-invoyisi yokuqala.
