Gusobanukirwa amanota ya IP y'umuvugizi w'inganda kuri sisitemu y'indangururamajwi idakingirwa na waterproof PA

Uburyo amanota ya IP agira ingaruka ku guhitamo indangururamajwi z'inganda

Gushyiraho uburyo buhamye bwo gupima imbuga za IP nk'igipimo cy'ibanze cya sisitemu ya PA y'indangururamajwi idapfa amazi mu nganda, mu nganda zikora peteroli, no mu nganda zikomeye. Muri ibi bihe, sisitemu zo kuvugira mu ruhame si ibintu byorohereza imikorere gusa; ni ibikorwa remezo by'ingenzi mu kubungabunga ubuzima bikenewe mu gutanga amakuru yihutirwa, gahunda zo guhunga no gutangaza amakuru buri munsi. Kubera iyo mpamvu, ubushobozi bwo kwihanganira ibidukikije bw'ibikoresho by'indangururamajwi bugena neza uburyo umuyoboro wose w'itumanaho wizewe.

Guhitamo amanota akwiye yo kurinda ikoranabuhanga (IP) ni inzira ikomeye cyane ihuza ubuhanga mu by'amajwi n'ubudahangarwa bw'ikoranabuhanga. Abahanga mu by'imashini bagomba gusuzuma uduce tw'ikirere, imiterere y'amazi, n'ubushuhe bw'ikirere kugira ngo bagaragaze ibikoresho bishobora gukomeza kwangirika kw'inganda. Kudahuza neza amanota ya IP y'indangururamajwi n'aho ikorera bituma ibice byayo byangirika vuba, ubushobozi bwo gusobanukirwa buke, ndetse amaherezo, no kunanirwa kwa sisitemu mu gihe itumanaho riba rikomeye cyane.

Impamvu amanota ya IP ari ingenzi mu kaga no mu gihe cyo gukora

Inshingano y'ibanze yasisitemu y'ubugenzuzi bw'ingandani ugukomeza gukora amasaha y'akazi kenshi, cyane cyane mu bihe by'ibibazo aho gutsindwa atari amahitamo. Ibipimo bya IP bitanga igipimo gishoboka cyo gusuzuma ingaruka zishobora guterwa n'ibidukikije, ari nabyo bitera gutsindwa vuba mu bikoresho by'ikoranabuhanga mu nganda. Umukungugu uturuka mu kirere ushobora kwirundanya ku byuma bikoresha ijwi bya transducer, bigatera gucika intege k'ubushyuhe cyangwa gufatana kwa mekanike, mu gihe ukwinjira k'ubushuhe bitera imiyoboro migufi, kwangirika kw'ikoranabuhanga ry'imbere, no kwangirika kw'udupira tw'amajwi dushingiye ku mpapuro.

Amakuru y’imibare agaragaza ingaruka mbi z’amafaranga n’imikorere y’ibikoresho bidashyirwa ku rutonde rw’ibikoresho. Indangururamajwi zitashyizwe mu nganda zifite ubushyuhe buri hejuru ya 70% zigaragaza igipimo cy’inanirwa cya 45% mu mezi 18 ya mbere yo kuzikoresha. Ibinyuranye n’ibyo, indangururamajwi za IP zitagira amazi zigaragaza neza zigabanya ihungabana rishingiye ku bidukikije kugeza munsi ya 2% mu gihe cy’imyaka itanu. Iri gabanuka rikomeye ry’igabanuka ry’ihungabana rigira ingaruka zitaziguye ku nganda, bigabanya ikiguzi kinini cyane giterwa no kubungabunga byihutirwa, guhagarika gukora, ndetse n’ibihano bishobora guterwa no kubahiriza amategeko agenga umutekano mu karere cyangwa OSHA.

Aho Indangururamajwi zifite IP-Rated zihurira muri sisitemu ya PA y'ibikomoka ku bimera

Sisitemu za PA zo mu nganda zose ntizikunze gukora ahantu hamwe; ahubwo, zikora ahantu hatandukanye mu kirere kimwe. Igishushanyo mbonera cyuzuye cy'amajwi gikoresha uburyo butandukanye bwo gupima amajwi ya IP mu nganda, gikoresha ibikoresho birinzwe cyane aho bikenewe gusa kugira ngo ingengo y'imari rusange irusheho kuba nziza hatabayeho gutakaza icyizere. Urugero, ibyumba byo kugenzura n'aho abayobozi bayobora ubusanzwe bisaba amajwi asanzwe yo mu rwego rw'ubucuruzi cyangwa ay'ikoranabuhanga riciriritse, kuko agenzurwa n'ikirere kandi nta tunyangingo tw'inganda dufite.

Iyo bigiye hanze mu kigo, urwego rw'uburinzi rukenewe rurazamuka. Aho gupakira ibikoresho n'ahantu ho kubika ibintu hafunze neza bisaba uburinzi bw'ibanze ku mukungugu uterwa n'umuyaga n'ubushuhe butaziguye. Ahantu ho gutunganya ibikoresho, cyane cyane ahakorerwa ibiribwa n'ibinyobwa cyangwa hatunganywa imiti, hakenera indangururamajwi zikomeye zidashobora kuvogerwa n'amazi zishobora kwihanganira amazi asukurwa n'umuvuduko mwinshi. Mu gushyira ku murongo ingaruka mbi ku bidukikije bya buri gace k'ikigo ku gipimo cya IP gikwiye, ibikoresho bihuza sisitemu bishobora gukora umuyoboro wa PA uhuza uruganda, utuma amajwi akwirakwira mu buryo bumwe kandi ibidukikije bigakomeza kubaho.

Icyo amanota ya IP y'umuvugizi w'inganda yemeza

Sisitemu yo gupima Ingress Protection (IP), igenwa ku isi yose n'amahame mpuzamahanga ya IEC 60529, itanga uburyo bukomeye kandi buhamye bwo gushyira mu byiciro urwego rw'uburinzi butangwa n'ibikoresho by'amashanyarazi. Ku bavuga rikijyana mu nganda, iyi ngingo ikuraho urujijo ku magambo nka "adashobora gutwarwa n'amazi" cyangwa "adashobora kwihanganira ikirere," isimbura amagambo yo kwamamaza n'ibipimo by'ibizamini bya laboratwari bishobora kongera gukoreshwa.

Gusobanukirwa neza icyo amanota ya IP y’umuvuduko w’inganda yemeza bituma abahanga mu by’amasoko bashobora kwemeza ko ibikoresho bizagumana n’imimerere runaka y’ibikoresho. Ayo manota asuzuma ubuziranenge bw’aho umuvuduko w’umuvuduko ukorera, gufunga imiyoboro y’insinga, n’inzitizi zirinda umuvuduko w’amajwi.

Uburyo Imibare ya mbere n'iya kabiri ya IP ikora

Kode ya IP igizwe n'imibare ibiri itandukanye, buri imwe ihagarariye icyiciro gitandukanye cy'ubudahangarwa bw'ibidukikije. Umubare wa mbere, kuva kuri 0 kugeza kuri 6, ugaragaza urwego rw'uburinzi bw'agace k'ibice bikomeye by'amahanga byinjiramo, kuva ku bikoresho binini n'intoki kugeza ku duce duto tw'umukungugu. Inota ya 6 igaragaza uburinzi bw'umukungugu wose, bisaba ikizamini cy'ubusa aho nta mukungugu ushobora kwinjira mu gace k'ibice mu gihe runaka.

Umubare wa kabiri, kuva kuri 0 kugeza kuri 9K, upima urwego rw'uburinzi ku mazi yinjira. Iki gipimo ntabwo ari umurongo ugororotse; gikubiyemo ubwoko butandukanye bw'amazi ahura na bwo, harimo guhumeka, amazi anyura mu kirere, gusuka amazi mu mazi, umuvuduko mwinshi, no kwibira mu mazi burundu. Urugero, umubare wa kabiri wa 5 ugaragaza uburinzi ku mazi anyura mu kirere (litiro 12.5 ku munota) uturutse mu cyerekezo icyo ari cyo cyose, mu gihe 6 isobanura uburinzi ku mazi anyura mu kirere (litiro 100 ku munota ku muvuduko wa kPa 100).

Icyo IP54, IP55, IP65, IP66, IP67, na IP68 bisobanuye

Kugira ngo bamenye uburyo bwo guhitamo sisitemu za PA z’indangururamajwi zidapfa amazi, injeniyeri bagomba gusobanukirwa ibipimo byihariye byo gupima amanota asanzwe ya IP mu nganda. Imbonerahamwe iri hepfo igaragaza ibipimo nyabyo by’izi nzego.

Igipimo cya IP66 muri rusange gifatwa nk'ibanze ku bikorwa nyabyo mu nganda no hanze, kuko gihamya ko gishobora kubaho mu gihe cy'imvura nyinshi no mu gihe cy'amazi ataziguye. IP67 na IP68 bigenerwa ibikorwa byihariye aho indangururamajwi zishobora kuba zitwikiriwe n'amazi by'agateganyo cyangwa burundu, nko muamacumbi y'ubucukuzi bw'amabuye y'agaciro akunze kwibasirwa n'imyuzurecyangwa inyubako zo gufatiramo ubwato mu mazi.

Ibyo Isuzuma rya IP ritagaragaza

Nubwo amanota ya IP y’umuvuduko w’inganda atanga amakuru y’ingenzi yerekeye ivumbi n’amazi, ntabwo ari ikimenyetso cyuzuye cy’uko ibidukikije biramba muri rusange. Ikibazo gikunze kugaragara mu buhanga ni uko amanota ya IP menshi agaragaza ko adashobora guhangana n’ibyago byose byangiza imikorere y’inyubako. IEC 60529 ntisuzuma uburyo icyuma gikingira imirasire ya ultraviolet (UV), ishobora kwangiza vuba pulasitiki isanzwe ya ABS mu bikoresho byo hanze.

Byongeye kandi, amanota ya IP ntabwo akubiyemo ingese cyangwa ingaruka z'umubiri. Indangururamajwi ishobora kuba idapfa amazi na gato (IP67) ariko igakomeza kugwa mu nyubako iyo ihuye n'umwuka uhumanya mu ruganda rwa peteroli. Mu buryo nk'ubwo, ubudahangarwa bw'ingaruka bupimirwa ukwabwo hakurikijwe igipimo cya IK (IEC 62262). Indangururamajwi ikomeye ishobora gusaba igipimo cya IK08 (ishobora kwihanganira ingaruka za 5-Joule) hiyongereyeho igipimo cya IP66 kugira ngo ikomeze kubaho mu bubiko burimo abantu benshi.

Guhitamo amanota ya IP hakurikijwe imikorere

Kugena amanota ya IP y’umuvuduko w’inganda bisaba kumenya neza ingaruka nyazo ku bidukikije by’agace runaka k’ikigo hakurikijwe ibipimo by’ibizamini bihuye n’ibipimo ngenderwaho bya IEC 60529. Kugena cyane bitera ikoreshwa ry’imari ritari ngombwa, mu gihe kugena ingano y’ibikoresho bidahagije byemeza ko byangiritse vuba. Uburyo bwo guhitamo bugomba kuba bushingiye ku mikorere isanzwe ndetse n’ibibazo bikomeye byo kubungabunga.

Inganda zitandukanye zifite imbogamizi zidasanzwe zigena atari gusa imiterere ya IP ahubwo n'imiterere ya sisitemu ya PA y'indangururamajwi idapfa amazi. Mu gushyira mu byiciro uduce tw'inganda mu byiciro bitandukanye by'ikoreshwa, abahanga bashobora gushyiraho uburyo bwo gutanga amasoko no kwemeza ko amajwi ahoraho mu bikorwa bitandukanye.

Inzu, Inzu zo hanze, Inzu yo kozamo amazi, n'Inzu yo mu mazi

Ibidukikije ni byo bigena uburyo bwo kwirinda kwinjira no kubaka ibikoresho. Ahantu ho gukorera ibikoresho mu nzu hatarimo amazi, ubusanzwe hakenera gusa uburinzi bwa IP54 kugira ngo birinde ivumbi ryo mu kirere. Ahantu ho hanze, nko mu byuma bipakira ibintu cyangwa ahantu ho guhungira, hahura n'imvura n'amazi bituruka ku muyaga, bigasaba nibura IP65.

Ku bidukikije bikomeye, ibisabwa birazamuka cyane. Ahantu ho gusukura ibiribwa cyangwa mu bigo bikora imiti hahura n'isuku ya buri munsi hakoreshejwe amazi ashyushye cyane avanze n'imiti ihumanya. Utu duce dukenera amanota ya IP66 cyangwa IP69K. Ibidukikije byo mu mazi, harimo n'ibikomoka ku bimera, harimo n'ibimera bisukura.ahantu hakorerwa peteroli mu mahangan'ibyambu byo ku nkombe, bihura n'ikibazo cy'umunyu ukomeza gutera ndetse n'ingaruka z'umuraba zishobora guterwa n'imiraba, bikaba bisaba uburinzi bwa IP66 cyangwa IP67.

Uburyo bwo kugereranya ibipimo bya IP, ibikenewe mu gufunga no gushyiramo amakuru

Igipimo cya IP cyizewe gusa nk'ibikoresho byo mu gipangu n'ibikoresho byo kuyishyiraho. Indangururamajwi ifite igipimo cya IP66 ntacyo imaze iyo inzu yayo yacitse bitewe n'ubushyuhe cyangwa icyuma cyo kuyishyiraho cyangiritse. Mu kugereranya amahitamo, injeniyeri bagomba gusuzuma ubufatanye hagati y'igipimo cya IP n'icyuma cyo mu gipangu. Urugero, icyuma gisanzwe cya 304 gishobora guhomba no kwangirika mu bidukikije byo mu mazi nubwo gifite indangururamajwi ifite igipimo cya IP67; bityo rero, icyuma cya 316L gifite umubare uhwanye na Pitting Resistance Equivalent Number (PREN) urenze 32 kirakenewe.

Ibikenewe mu gushyiraho insinga bigira ingaruka ku buziranenge bw'isuzuma rya IP. Aho insinga zinjira niho hakunze kugaragara ko indangururamajwi zidapfa kwinjira. Abashyiraho insinga bagomba gukoresha insinga zikwiye (urugero: insinga za M20 IP68 brass glands) kandi bakareba neza ko insinga zidasaba gucukurwa mu nzu y'indangururamajwi ifunze, ibyo bikaba byahita bikuraho icyemezo cya IP cy'uwakoze insinga.

Uburyo kwirinda amazi bishobora kugira ingaruka ku mikorere y'ijwi

Kugira ngo umuntu agere ku gipimo cya IP cy’umuvuduko wo hejuru mu nganda, akenshi bisaba ko habaho ubwumvikane buke mu by’ikoranabuhanga bushobora guhindura imikorere y’umuvuduko w’ijwi ry’icyuma. Kugira ngo agere ku gipimo cya IP66 cyangwa IP67, abakora bagomba kurinda uduce tw’umuvuduko w’amazi duto cyane. Ibi bikunze kugerwaho hakoreshejwe uburyo bwihariye bwo gufunga umuvuduko w’ijwi bw’amazi (nk’uduce twa PTFE) cyangwa bagafunga umushoferi inyuma y’agace k’imbere gakomeye kandi gatanga ijwi.

Ubu buryo bwo kwirinda amazi butuma habaho impedance y'amajwi. Amajwi afite frequency nyinshi nta ngufu zo kwinjira mu buryo bworoshye mu ruhu rw'amazi. Kubera iyo mpamvu, indangururamajwi ifite urwego rwa IP66 ishobora kugabanuka hagati ya dB 2 na 4 ku rugero rw'umuvuduko w'amajwi (SPL) ku nshuro zirenze 8 kHz ugereranije n'indi idafite point. Abashushanya sisitemu bagomba kwita kuri ubu buryo bwo kugabanya frequency nyinshi mu gihe cyo gukora modelling y'amajwi, akenshi bishyura binyuze mu kongera imiterere ya amplifier cyangwa gushyiraho indangururamajwi zifite uburebure bwinshi kugira ngo zikomeze intego za Speech Transmission Index (STI) zo gutabara mu buryo bwihutirwa.

Uburyo bwo kwemeza ibirego bya IP rating

Nubwo abakora ibicuruzwa bakunze kwamamaza amanota menshi ya IP ku bahanga mu byuma, abahanga mu by’ubucuruzi n’inzobere mu gutanga amasoko bagomba kwemeza neza ibi birego binyuze mu nyandiko zisanzwe no gusesengura igereranya. Isoko ry’amajwi mu nganda rikubiyemo ubwoko bwinshi bw’ibikoresho byiza, kandi gufata ibipimo byo kwamamaza ku giciro cyabyo bishobora guteza ibibazo bikomeye muri sisitemu za PA zishinzwe umutekano w’ubuzima.

Igenzura risaba gusobanukirwa byimbitse amabwiriza mpuzamahanga y’ibizamini n’ubushobozi bwo gutandukanya ibirego byizewe n’amakuru ya laboratwari. Gushyiraho amabwiriza ahamye yo kugenzura byemeza ko sisitemu ya PA y’indangururamajwi idapfa amazi izakora neza nk’uko byateguwe mu gihe cy’imikorere yayo.

Raporo z'ibizamini n'amahame yo gusaba

Kugira ngo hemezwe amanota ya IP, amatsinda ashinzwe gutanga amasoko agomba gutegeka ko hatangwa raporo zemewe z’ibizamini ziturutse muri laboratwari zemewe n’abandi. Kwiyemeza n’uruganda ni ibisanzwe ku manota make (IP54), ariko ibirego byo ku rwego rwo hejuru (IP66, IP67, IP68) bigomba gushyigikirwa n’igenzura ryigenga. Laboratwari ipima igomba kuba ifite icyemezo cya ISO/IEC 17025, yemeza ko ikigo gifite ibikoresho bigenzuwe n’ubushobozi bwa tekiniki bwo gukora ikizamini cya IEC 60529 neza.

Mu gusuzuma raporo y'ikizamini, injeniyeri zigomba kugenzura imiterere y'ikizamini cyihariye. Kuri raporo ya IP66, inyandiko zigomba kugaragaza neza ko indangururamajwi yashyizwemo umunwa wa mm 12.5 itanga litiro 100 z'amazi ku munota ku ntera iri hagati ya metero 2.5 na 3 mu gihe cy'iminota 3, kandi ko igenzura ry'imbere ryakurikiyeho ryagaragaje ko nta mazi yangiza yinjira.

Uburyo amanota ya IP agereranywa n'andi mabwiriza

Mu masoko yo muri Amerika y'Amajyaruguru, injeniyeri zikunze guhura n'ibipimo ngenderwaho bya NEMA 250 hamwe cyangwa aho kuba ibipimo ngenderwaho bya IEC 60529 IP. Nubwo hari aho bihurira, ibipimo ngenderwaho byombi ntibishobora guhindurwa neza. Ibipimo ngenderwaho bya IP by'umuvuduko w'inganda bipima neza uburyo bwo kwirinda ibintu bikomeye n'amazi, mu gihe ibipimo bya NEMA byongera ibindi bintu bihungabanya ibidukikije nko kurwanya ingese, gukonja, no gusohora amavuta.

Urugero, amanota ya NEMA 4X akunze gufatwa nk'angana na IP66 ku bijyanye no kurinda umukungugu n'amazi. Ariko, "X" muri NEMA 4X igaragaza ko nta kwangirika kw'ibintu byagaragaye, akenshi bisaba ko agace gakingira kugira ngo kagume mu kizamini gikomeye cyo gusukura umunyu amasaha 200. Indangururamajwi ya IP66 yakozwe muri plastiki isanzwe ya ABS yananirwa gukurikiza amabwiriza ya NEMA 4X yo kwangirika. Kubwibyo, iyo hagenzurwa ibisabwa ku bidukikije byangiza cyane, injeniyeri zigomba kureba kure y'amanota ya IP hanyuma zigasaba ibyangombwa by'inyongera bya NEMA cyangwa ibisubizo byihariye bya ASTM B117 by'ibizamini by'umunyu.

Ibiranga Umutuku mu Bisobanuro by'Umuvuduko w'Ijwi rya IP

Mu gihe cyo gusuzuma ibipimo, ibimenyetso byinshi bishobora kugaragaza ubuhanga butari bwiza cyangwa kwamamaza ku buryo butari bwiza ku bijyanye n'igipimo cya IP cy'umuvuduko w'inganda. Ikimenyetso gikuru cyane kigizwe n'ibivugwa bya IP68 bidasobanutse neza. Dukurikije IEC 60529, uburebure n'igihe byihariye byo gupima IP68 bigomba gusobanurwa n'uwabikoze, mu gihe birengeje urugero rwa IP67 (metero 1 mu minota 30). Niba urupapuro rw'ibipimo ruvuga "IP68" ariko ntirugaragaze ibipimo nka "kwinjira muri metero 2 mu masaha 24," amanota ntabwo atuzuye kandi nta gaciro afite.

Ikindi kintu cy’ingenzi ni ukuba hari ama-switch ya mekanike adafunze cyangwa ama-terminal blocks agaragara ku ndangururamajwi ifite IP65 cyangwa irenga. Indangururamajwi nyazo zidapfa amazi zikoresha insinga zifunze n'ibyumba by'imbere by'indangururamajwi. Niba igitabo cy'amabwiriza gisaba ko installer ifungura icyumba cy'ibanze cy'indangururamajwi kugira ngo ihuze insinga, amanota ya IP y'uruganda aragabanuka igihe cyose icyuma gikorerwa mu murima. Indangururamajwi nziza zo mu nganda zitandukanya agasanduku k'insinga n'agasanduku k'insinga gakingira transducer kugira ngo zigumane agasanduku k'ibidukikije.

Uburyo bwa nyuma bwo gutoranya abavuga mu nganda

Guhitamo kwa nyuma amanota ya IP y’indangururamajwi mu nganda bisaba uburyo buhuriweho burenze guhitamo gusa umubare munini uboneka. Abahuza sisitemu bagomba guhuza amakuru ajyanye n’ibidukikije, ibisabwa mu ijwi, n’ingengo y’imari kugira ngo bagaragaze sisitemu ya PA y’indangururamajwi idapfa amazi itanga ubumenyi bwizewe mu gihe kirekire cy’imikorere.

Amasoko y’ingamba areba amanota ya IP atari gusa nk’ibipimo bya tekiniki, ahubwo nk’ikintu cy’ingenzi gitera ikiguzi cyose cy’ubwikorezi (TCO) muri sisitemu. Umuyoboro w’itumanaho wagenwe neza ugabanya ibikorwa byo kubungabunga, ukagabanya igihe cyo kudakora, kandi ukareba ko itumanaho rijyanye n’umutekano w’ubuzima rikomeza gukora mu gihe cy’impanuka zikomeye.

Uburyo bwo kuringaniza ibidukikije, imikorere, n'ingengo y'imari

Kunganya ibidukikije, imikorere, n'ingengo y'imari bisaba isesengura ryimbitse rya TCO. Abavuga rikijyana bafite amanota menshi bategeka ko hakoreshwa amafaranga menshi y'ibanze. Urugero, umuntu ukoresha ikoranabuhanga rya IP.Ifite icyemezo cya ATEX, Indangururamajwi y'icyuma kitagira umugese ifite agaciro ka IP66 ishobora kugira igiciro cya 40% kugeza kuri 60% ugereranyije n'iya aluminiyumu isanzwe ya IP54. Ariko, gushyira indyo ya IP54 ihendutse ahantu hanini ho gukaraba bizatera gucika intege kenshi.
