Indlela Yokuthola Umkhiqizi Wezipikha Ongcono Kakhulu Webhizinisi Lakho

Umkhiqizi wesipikha esenziwe ngokwezifiso usiza amasayithi ezimboni ukuthi asuke ekukhipheni umsindo ojwayelekile aye ekuxhumaneni okuqondene nohlelo lokusebenza. Ezindaweni ezinomsindo, zangaphandle, noma eziyingozi, umklamo ofanele unganquma ukuthi umlayezo uzwakala kahle futhi usetshenziswa ngokushesha.

Kungani Umkhiqizi Wesipikha Esingokwezifiso Ebalulekile Kumaphrojekthi Esipikha Sezimboni

Ukusebenza kwezipikha zezimboni kuncike endaweni ezungezile, hhayi nje ilebula lomkhiqizo. Iyunithi ejwayelekile ingasebenza ehhovisi elithule, kodwa amafektri, amachweba, imigudu, kanye nezitshalo zidinga ukuphuma okuhlukile kwe-acoustic, ukuvikelwa kokuvala, kanye nezindlela zokufaka.

Ukulawulwa komsindo kuyinkinga eyinhloko yokuklama umsindo wezimboni. I-OSHA iphawula ukuthi izindawo zokusebenza ezinomsindo omkhulu kumele zisebenzise izilawuli zobunjiniyela lapho kungenzeka khona, futhi indinganiso yayo yomsindo ibeka imikhawulo yokuchayeka eqokomisa ukuthi kunzima kangakanani ukuxhumana ezindaweni ezinomsindo.Ukubuka Konke Kokuchayeka Komsindo Emsebenzini we-OSHAfuthiI-OSHA 29 CFR 1910.95bonisa ukuthi kungani ukuqinisa izwi okucacile kungeyona into yokuzikhethela ezindaweni eziningi.

Ukwakheka ngokwezifiso kunciphisa nengozi yokuhlanganiswa. Ithimba lephrojekthi livame ukudinga uhlelo olulodwa ukuze lisebenze nge-paging, i-intercom, ukushaya ucingo oluphuthumayo, kanye nezilawuli zokuthumela. Yingakho abathengi abaningi bekhetha umhlinzeki ongavumelanisa ukuphuma kwesipikha, isilinganiso se-enclosure, kanye ne-logic yokulawula ku-specification eyodwa.

Izigaba Zomkhiqizo Eziyinhloko Okufanele Zibuyekezwe Ngaphambi Kokukhetha Umhlinzeki

Abahlinzeki bezokuxhumana kwezimboni bavame ukuhlela iphothifoliyo yabo ngezigaba ezimbalwa eziyinhloko. Isibonelo, isayithi likaJoiwo lihlanganisa imikhiqizo ibe izinhlelo zocingo zezimboni, izingcingo ezingaqhumi futhi eziphephile ngokwemvelo, izingcingo ezingamelani nesimo sezulu nezilimazayo, izinhlelo ze-intercom nezishayela ucingo eziphuthumayo, kanye nezinhlelo zekheli lomphakathi kanye nezinhlelo zomsindo zesayithi.Iwebhusayithi eyinhloko yeJoiwokuyisiqalo esiwusizo sokubuyekeza lezo zigaba.

Ithebula Lokuqhathanisa: Izigaba Zomkhiqizo Eziyinhloko kanye Nezimo Zokusetshenziswa Ezijwayelekile

Lezi zigaba zibalulekile ngoba zihambisana ngqo nezidingo zokuthenga. Umthengi ofuna isipikha sefektri yokuhluza akadingi indawo efanayo, isitifiketi, noma ihadiwe yokufaka njengomthengi wesistimu ye-PA yekhampasi.

Imigomo Yobuchwepheshe Echaza Isikhulumi Esihle Sezimboni

Ukuvikelwa kokungena kungenye yezihlungi zokuqala zobuchwepheshe. I-IEC ichaza ukuthi izilinganiso ze-IP zihlukanisa ukumelana kokuvala uthuli namanzi ngaphansi kwe-IEC 60529, kanti inombolo yokuqala ihlanganisa izinto eziqinile kanti eyesibili ihlanganisa uketshezi.Umhlahlandlela wokulinganisa i-IP we-IECyiyona ndlela ecacile yokuhumusha lezo zinombolo.

Ezindaweni ezingaphandle noma ezihlanza amanzi, i-IP66 ivame ukuba yinhloso ewusizo ngoba ibonisa ukuvikelwa okuqinile kothuli kanye nokuvikelwa kumajethi amanzi anamandla. Ezindaweni eziyingozi, ukuvikelwa kwendawo ebiyelwe kuphela akwanele; idivayisi idinga futhi indlela efanele yokuqinisekiswa komkhathi oqhumayo. Amakhasi e-ATEX eKhomishini yaseYurophu achaza uhlaka lwemishini ehloselwe izimo eziqhumayo.Ukubuka konke kweKhomishini yaseYurophu i-ATEXfuthiIziqondiso ze-ATEX 2014/34/EUyizinkomba ezibalulekile.

Ithebula Lokuqhathanisa: Ukuhlolwa Kwezincazelo Ezivamile Zomsindo Wezimboni

Izinga lokucindezela komsindo kufanele lifaniswe nendawo, hhayi ukuqagela. Njengomthetho olula, umphumela wesipika kufanele udlule umsindo ozungezile ngomkhawulo osebenzisekayo ukuze inkulumo ihlale iqondakala. Empeleni, onjiniyela bavame ukulinganisa umkhawulo odingekayo kusukela esimweni sokusebenza esiphezulu kakhulu, bese bewuqinisekisa ngesikhathi sokusebenza.

Indlela Umkhiqizi Wesipikha Esenziwe Ngokwezifiso Athuthukisa Ngayo Ukwakheka Kwesistimu Ye-PA

Ubunjiniyela obungokwezifiso buthuthukisa izinhlelo ze-PA ngokufanisa ukumbozwa, amandla, kanye nokulawula nokwakheka kwendawo. Indawo yokugcina impahla, umhubhe, noma isitshalo sokucubungula kungadinga amaphethini ahlukene ophondo, ubukhulu be-amplifier, kanye ne-logic yokuhlukanisa ukuze kugwenywe izindawo ezifile kanye ne-echo.

Ukucaca kwezwi ngokuvamile kubaluleke kakhulu kunevolumu eluhlaza. Isiqondiso se-OSHA mayelana nokulawula umsindo sigcizelela izilawuli zobunjiniyela, futhi leso simiso sisebenza nasekwakheni kwe-PA: uhlelo kufanele lunikeze inkulumo eqondakalayo endaweni yokulalela, hhayi nje inombolo ephezulu ye-decibel.Ukuvezwa Nokulawulwa Kwe-OSHAisekela leyo ndlela yobunjiniyela kuqala.

Izivalo ezenziwe ngokwezifiso nazo zinciphisa amazinga okuhluleka. Izindlu ezingamelani nokugqwala, ukufakwa kwekhebula elivaliwe, kanye namabhuleki abekezelela ukudlidliza ngokuvamile kuyadingeka emachwebeni, emagcekeni angaphandle, nasezindaweni zezimboni ezisindayo. Umhlinzeki olawula uchungechunge lokuklama nokukhiqiza ngokuvamile angagcina le mininingwane ihambisana kuwo wonke amaphrojekthi.

Lokho Okufanele Kubuzwe Amathimba Okuthenga Ngaphambi Kokufaka Abahlinzeki Abakhethiwe

Amaqembu okuthenga kufanele abuze ngezindinganiso, ukufakwa, kanye nokugcinwa ngaphambi kokuqhathanisa amanani. Umhlinzeki ongcono kakhulu akahlali eshibhile; nguyena ongabhala phansi ukufaneleka kwendawo futhi asekele uhlelo ngemva kokulethwa.

• Yikuphi ukuhlolwa kwesilinganiso se-IP kanye nokuhlolwa kwemvelo okutholakalayo kwemodeli eqondile?
• Ingabe umkhiqizo udinga i-ATEX, uphephile ngokwemvelo, noma olunye ugunyazo oluqondene nesayithi?
• Ingabe isikhulumi singahlangana ne-PA ekhona, i-intercom, noma uhlelo oluphuthumayo?
• Yiziphi izinto zokufakelwa kanye nezesekeli ezifakiwe?
• Izingxenye ezisele, ukulungiswa, kanye nokufakwa kwezinye ziphathwa kanjani phakathi nomjikelezo wokuphila kwephrojekthi?

Le mibuzo ibaluleke kakhulu kubathengi abasekelwe kumaphrojekthi. Umhlanganisi wesistimu angadinga umthengisi oyedwa wetheminali, omunye we-amplifier, kanye nowesithathu wezesekeli, okwandisa izindleko zokuxhumanisa kanye nengozi yokulethwa.

Indlela Yokufaka Uhlu Olufushane Lwabahlinzeki Bezikhulumi Zezimboni kanye Nemisebenzi Yesistimu ye-PA

Uhlu olufushane olusebenzayo kufanele lufake abakhiqizi abangochwepheshe kanye nemikhiqizo yomsindo yezimboni eseyivele ikhona. Iwebhusayithi eqondiwe ibalulekile ngoba inikeza uhla olubanzi lwemikhiqizo yokuxhumana yezimboni, kanti abanye abahlinzeki abaziwayo emakethe ebanzi bangase bafaneleke kuye ngesifunda, izidingo zesitifiketi, kanye nesabelomali.

Uhla Lwezinsizakalo: Imigomo Yohlu Olufushane Lwezinhloso

Kubathengi abadinga indlela yomthombo owodwa, iwebhusayithi eyinhloko ingabuyekezwa kanye nemindeni yemikhiqizo yayo efanaizinhlelo zocingo zezimboni, ocingo olungangenisi isimo sezulu, izixazululo zocingo eziphuthumayo, futhiizinhlelo zekheli lomphakathiLezi zixhumanisi zisiza ukuhlanganisa izigaba zomkhiqizo nezidingo zangempela zephrojekthi.

Lapho Umklamo Owenziwe Ngokwezifiso Udala Inani Eliphezulu Kakhulu

Ukwakheka ngokwezifiso kudala inani elikhulu ezindaweni ezinzima, ezilawulwayo, noma ezinabantu abaningi. Izitshalo zamakhemikhali, izindawo zokumba, amajele, amakhampasi, izindawo zokuthutha, kanye namagumbi okuhlanza konke kubeka izidingo ezahlukene emandleni okuvalelwa, ukuhlanzeka, isivinini sokuphendula, kanye nokusebenza kwe-acoustic.

Isibonelo, isipikha sangaphandle esingamelani nesimo sezulu singadinga ukumelana nokugqwala kanye nokufakwa kwekhebula elivaliwe, kuyilapho i-terminal ye-PA yasejele ingadinga ukumelana nokucekelwa phansi kanye nehadiwe engaphazanyiswa. I-intercom yegumbi lokuhlanza ingadinga izindawo ezihlanzwa kalula kanye nokulungiswa kwezinhlayiya ezincane, okushintsha izinto kanye nendlela yokufaka.

Yingakho ingxoxo engcono kakhulu yomhlinzeki iqala ngesimo sokusetshenziswa. Uma isimo sendawo sesicacile, indawo efanele yokuvala, izinga lokukhipha, kanye nendlela yokulawula kuba lula kakhulu ukuyichaza.

Imibuzo Evame Ukubuzwa

Iyini inzuzo eyinhloko yomkhiqizi wezipikha ezenziwe ngokwezifiso kumaphrojekthi ezimboni?

Inzuzo eyinhloko ukulingana. Ubunjiniyela obungokwezifiso buvumelanisa ukuvikelwa kwendawo ebiyelwe, izinga lokukhipha, ukufakwa, kanye nokuhambisana kwesistimu nezimo zangempela zesayithi. Lokho kunciphisa ukwehluleka kokuxhumana, ukulungiswa kabusha kokufakwa, kanye nezinkinga zokugcinwa ezindaweni ezinomsindo noma eziveziwe.

Ngingakhetha kanjani phakathi kwe-IP66 kanye namazinga okuvikela aphezulu?

Qala ngendawo ezungezile. I-IP66 ivame ukufanelana nokuchayeka kakhulu othulini noma emanzini, kodwa izingozi zokuwasha noma zokucwiliswa kakhulu zingadinga isilinganiso esiphezulu. I-IEC 60529 ichaza ikhodi ye-IP, ngakho-ke ukukhetha kokugcina kufanele kulandele iphrofayili yokuchayeka kwesayithi.

Kungani ukuqondakala kwenkulumo kubaluleke kakhulu kunomthamo?

Umsindo wodwa awuqinisekisi ukuqonda. Ezindaweni zezimboni, ama-echo, umsindo wemishini, kanye nebanga kungaphazamisa inkulumo. Uhlelo lwe-PA oluklanywe kahle kufanele lunikeze okuqukethwe kwezwi okucacile endaweni yokulalela, hhayi nje ezingeni lomsindo eliphakeme.

I-ATEX ifaneleka nini ohlelweni lwezikhulumi zezimboni noma lwe-PA?

I-ATEX iba yinto efanele uma imishini ihloselwe izimo ezingase ziqhume. Kulezo zimo, indawo ebiyelwe kanye nomklamo kagesi kumele kulandele uhlaka olufanele lomoya oqhumayo, hhayi nje izidingo ezijwayelekile zokuqina kwangaphandle.

Yini okufanele umthengi ayicele ngaphambi kokufaka i-oda lephrojekthi?

Umthengi kufanele acele incazelo eqondile yemodeli, isilinganiso se-IP, amadokhumenti esitifiketi, imininingwane yokufaka, inqubomgomo yezingxenye ezisele, kanye namanothi okuhlanganisa. Lawo madokhumenti asiza ukuqinisekisa ukuthi umkhiqizo uhambisana nendawo, uhlelo lokulawula, kanye nohlelo lokulungisa.
