Izixhumi Ezingangeni Manzi Zentambo ye-M12 Zidlula i-IP55 Zokufakwa Kokufakwa Kokulawula Kwangaphandle

Eminyakeni emithathu edlule, ngathola ucingo oluthukile oluvela kumqhubi wepulazi lelanga eSifundazweni saseJiangsu. Uhlelo lwakhe lwe-SCADA lwalungasebenzi ngesikhathi kunemvula enkulu. Indawo yokulawula kwelinye lamabhokisi okuhlanganisa yayivuza, futhi izinhlangano zesixhumi se-M8 ngaphakathi zahluleka. Amahora angamashumi amane nesishiyagalombili okungasebenzi, iqembu lenkonzo yasensimini labantu abayisithupha, kanye nesigaba sesijeziso esibalulekile esivela kumqhubi wegridi kamuva, wangibuza umbuzo ebengilokhu ngiwuzwa ngezindlela ezahlukene kusukela ngaleso sikhathi: "Ngingaqinisekisa kanjani ukuthi lokhu akuphinde kwenzeke?" Impendulo, njengoba ngimchazele ngaleso sikhathi futhi njengoba ngizochaza kulesi sihloko, ayikho nje ekukhetheni isilinganiso se-IP esifanele sendawo yakho, kodwa ekuqondeni ukuthi imininingwane yesixhumi - ikakhulukazi indinganiso yesixhumi esingangeni manzi ye-M12 - isebenzisana kanjani nomklamo wesistimu yakho iyonke, imikhuba yakho yokufaka, kanye nezinqubo zakho zokulungisa.

Ngemva kokusebenza nabafaki bemishini ezenzakalelayo yezimboni kanye nezinkontileka zikagesi ezindaweni eziningi zokufaka ngaphandle - amapulazi elanga, amabhokisi okulawula i-wind turbine, amakhabethe esignali yethrafikhi, izinhlelo zokulawula ukukhanya kwangaphandle, kanye nezindawo zokuvala izikhungo zokuhlanza amanzi - ngithuthukise isithombe esicacile sokuthi imininingwane yesixhumi se-M12 iqondwa kahle kuphi nokuthi ihunyushwa kanjani ngokungeyikho. Izindaba ezinhle ukuthi izixhumi ze-M12 ezihlangabezana ne-IEC 61076-2-101 ziphakathi kwezingxenye zokuxhuma ezithembeke kakhulu ezitholakalayo zokusetshenziswa ngaphandle kwezimboni. Izindaba ezimbi ukuthi "ukuhlangana ne-IP55" kudathashethi akuhumushi ngokuzenzakalelayo ukuthi "kuzohlala iminyaka emihlanu kukhabhinethi eseceleni komgwaqo eSifundazweni saseGuangdong ngesikhathi sesizini yesiphepho" uma isixhumi singachazwanga kahle, sifakiwe, futhi sinakekelwa.

Kulesi sihloko, ngizohamba ngendinganiso yobuchwepheshe echaza ukusebenza kwesixhumi se-M12, ngichaze ukuthi kusho ukuthini ngempela i-IP55 kanye nezilinganiso eziphakeme ngokwemigomo esebenzayo, nginikeze uhlaka lokukhetha oluchaza izimo zokufakwa zangempela, futhi ngabelane ngalokho engikufundile ngokwehluleka - kufaka phakathi ibhokisi lokuhlanganisa ipulazi lelanga eliqale le ngxoxo.

Kungani Ukuvuza Kwakho Kwendawo Yangaphandle Kungaba Inkinga Yesixhumi Empeleni

Ake ngiqale ngombono ongalungile ovamile engiwuthola cishe kuzo zonke izihlaziyi zokuhlolwa kwangemva kokufa engizenzayo mayelana nokwehluleka kokungena kwamanzi e-enclosure: umcabango wokuthi i-enclosure ngokwayo yehlulekile. Ezimweni eziningi engizihlolayo, i-enclosure gasket ayiphelele. Indawo yokungena kwamanzi yangempela isemaphuzwini okungena ngekhebula - ikakhulukazi esibonakalayo sokuxhuma-kuya-enclosure kanye nasesibonakalayo sokuxhuma-kuya-device. Yingakho nje isixhumi esicacisiwe futhi esifakwe kahle ngokuvamile siyisici esibaluleke kakhulu sokuqina kwamanzi kuyo yonke inhlangano ye-enclosure.

Ngesikhathi ngivakashela lelo pulazi lelanga eJiangsu, ibhokisi lokuhlanganisa lalilinganiselwe i-IP65 lodwa. I-gasket ezungeze umnyango yayiphelele. I-condensate drain yayicacile. Kodwa izindlala zekhebula lapho izintambo zasensimini zangena khona ebhokisini kwakuyizindlala zekhebula ze-nylon ezijwayelekile ngaphandle kokufaka ezinye izihlanzi zokuvala, kanti izixhumi ezibunjiwe kusengaphambili ezintanjeni zenzwa zazihleli endaweni yokufaka iphaneli ene-O-ring seal eyisisekelo kuphela. Ngesikhathi sesiphepho, imvula eqhutshwa ngumoya yaphoqeleka ukungena ezintanjeni zokufaka iphaneli ngesenzo se-capillary, futhi ukusuka lapho yangena ngaphakathi kwendawo ebiyelwe. Indawo ebiyelwe ngokwayo yayilungile. Izixhumi zaziyisixhumanisi esibuthakathaka.

Le ndlela iphindaphinda kuzo zonke izinhlobo zokufakwa. Ngibone imodi efanayo yokwehluleka kumakhabethe ezimpawu zomgwaqo eFujian (lapho izimvula zemvula zidala izimo zomswakama ophezulu eziqhubekayo), emabhokisini okulawula izitshalo zokwelashwa kwamanzi eShandong (lapho ukuminyana okuvela ekushiseni kuhlangana khona nokuvezwa kokungcola), kanye nasezindaweni zokushaja ze-EV eZhejiang (lapho ukuwasha ukucindezela kokuhlanza kudala ukuvezwa kwamanzi okucindezela okuphezulu okwesikhashana). Kuzo zonke izimo, isixhumi sasiyindawo yokuqala yokwehluleka - hhayi indawo ebiyelwe.

Ukuqonda i-IEC 61076-2-101: Izinga Elichaza Ukusebenza kwe-M12

Uma ucacisa izixhumi ze-M12 zezinhlelo zokusebenza zangaphandle zezimboni, udinga ukuqonda ukuthi indinganiso ye-IEC 61076-2-101 ihlanganisani ngempela, futhi okubaluleke ngokulinganayo, lokho engakuqinisekisi. Le ndinganiso, enesihloko esithi "Izixhumi zemishini kagesi — Ingxenye 2-101: Izixhumi eziyindilinga — Imininingwane yemininingwane yezixhumi ze-M12 ezinezikulufo ezikhiywayo," iwumbhalo oyisisekelo ochaza ubukhulu bemishini, ukuhlelwa kokuxhumana, kanye nezidingo zokusebenza kwezixhumi ze-M12 ezisetshenziswa ekwenziweni kwezicelo zokwenza izinto ngokuzenzakalela kwezimboni kanye nokulawula.

Indinganiso ichaza izici eziningana ezibalulekile amaqembu okuthenga kanye nonjiniyela okudingeka bazihlole ngokucophelela. Okokuqala, icacisa indlela yokukhiya: Izixhumi ze-M12 zisebenzisa umklamo wokukhiya ngezikulufo onentambo yesilisa emzimbeni wesixhumi efaka umgodi wephaneli elinomucu wesifazane, noma indlela yokukhiya ngesitayela se-bayonet. Uhlobo lokukhiya ngezikulufo yilokho abantu abaningi abakushoyo uma bethi "isixhumi esinomucu we-M12," futhi yilo mklamo ohlinzeka ngokusebenza kokuvala okuthembekile kakhulu ezindaweni zangaphandle. Intambo yesikulufo idala uphawu oluvela ensimbini luye ensimbini noma oluvela ensimbini luye epolimeni olungamelani nokukhululeka okubangelwa ukudlidliza - isidingo esibalulekile kunoma yiluphi uhlelo lokusebenza lapho kukhona khona ukujikeleza kokushisa noma ukudlidliza komshini.

Okwesibili, indinganiso ichaza amalungiselelo okuxhumana. Okuvame kakhulu ekuxhumeni kwezinzwa zezimboni kanye ne-actuator yi-A-coded (4-pin yezinzwa ze-DC namandla), i-B-coded (5-pin ye-Fieldbus Foundation kanye ne-Profibus), kanye ne-D-coded (4-pin ye-100M Ethernet). Kuzinhlelo zokusebenza zokuvala zangaphandle ezihilela ukusatshalaliswa kwamandla kanye nesignali, ukucushwa kwe-A-coded 4-pin yikho okusetshenziswa kakhulu, ngokuvamile kulinganiswa kuze kufike ku-250V AC noma i-250V DC kanye ne-4A continuous current ngokuxhumana ngakunye. Izixhumi ze-X-coded (8-pin, ezisetshenziselwa i-gigabit Ethernet) ziya ngokuya zivamile ezinhlelweni zokusebenza zokuvala ezihlakaniphile lapho kudingeka khona ukuxhumana kwedatha okusheshayo kanye namandla.

Okwesithathu, futhi lena yingxenye ebaluleke kakhulu ekusetshenzisweni kwe-IP55 yangaphandle: I-IEC 61076-2-101 ichaza izinga lokuvikelwa kwe-IP elilinganiselwe ngokusekelwe ekwakhiweni kwesixhumi kanye nokwakhiwa kokuvala. Kodwa-ke, indinganiso icacisa izimo zokuhlola — ngokuvamile ezenziwa ngaphansi kwezimo zelebhu ezilawulwayo ezinezixhumi ezihlanzekile kanye namanani e-torque acacisiwe — ezingabonisi ngempela izimo ekufakweni kwangempela kwangaphandle ezinyangeni eziyisithupha ngemuva kokuba isixhumi sivezwe emisebeni ye-UV, ukujikeleza kokushisa, kanye nokucindezeleka komshini kokufakwa kwensimu.

Leli phuzu lokugcina libalulekile. Uma umenzi ethi "isilinganiso se-IP67 ngokwe-IEC 61076-2-101," empeleni abakushoyo ukuthi isixhumi esisha, esihlanzekile, esihlanganiswe kahle ngokwemiyalelo yabo yokufaka, siphumelele ukuhlolwa kwe-IP67 ngaphansi kwezimo zelebhu. Ukusebenza kwensimu kwaleso sixhumi ngemva kweminyaka emibili yokuchayeka ngaphandle kuncike ngokuphelele ezintweni ezingaphandle kobubanzi bezinga: ukuzinza kwe-UV kwezinto ezihlala, ukungafani kokukhula kokushisa phakathi komzimba wesixhumi kanye nephaneli yokufaka, ukugcinwa kwe-torque yendlela yokukhiya izikulufo, kanye nekhwalithi yomklamo we-clamp yekhebula ovimbela ukukhishwa kwekhebula ekudluliseni ukucindezeleka esivalweni.

I-IP55, i-IP67, kanye ne-IP69K: Okushiwo Yizinombolo Empeleni Ekufakweni Kwakho

Uhlelo lokulinganisa lwe-IP (Ingress Protection) luchazwa yi-IEC 60529 futhi lunikeza indlela ejwayelekile yokuchaza izinga lokuvikelwa elinikezwa yizimbobo zikagesi ezimelene nezinto eziqinile kanye noketshezi. Isilinganiso siqukethe izinombolo ezimbili: esokuqala sibonisa ukuvikelwa ezintweni eziqinile (0-6), kanti esesibili sibonisa ukuvikelwa koketshezi (0-9K).

Kuzinhlelo zokusebenza zokuxhumanisa i-control enclosure yangaphandle, izilinganiso ezintathu ozohlangana nazo njalo yi-IP55, IP67, kanye ne-IP69K. Ukuqonda ukuthi isilinganiso ngasinye siqinisekisa ini nokuthi yini esingayiqinisekisi kubalulekile ekwenzeni ukukhetha okufanele.

I-IP55 isho ukuthi isixhumi sivikelwe ekungeneni okulinganiselwe kothuli (isilinganiso "5": "sivikelwe othulini" — ukungena kothuli akuvinjelwanga ngokuphelele, kodwa akungeni ngobuningi obanele ukuphazamisa ukusebenza okwanelisayo) futhi kuvikelwe ekungeneni kwamanzi okuvela kumajethi amanzi avela kunoma iyiphi indlela (i-"5" ngemuva kuka-"x" yokuvikela uketshezi). Ukuhlolwa kwejethi yamanzi kwe-IPX5 kusebenzisa i-nozzle ene-orifice engu-6.3mm, ukufafaza amanzi ngesivinini sokugeleza esingamalitha ayi-12.5 ngomzuzu ngokucindezela okungu-30 kPa ukusuka ebangeni elingamamitha ama-3. Lokhu kulingisa ukuvezwa kwemvula noma ukuchayeka emanzini kodwa akulingisi ukucwiliswa noma ukugeza ngokucindezela okuphezulu.

I-IP67 isho ukuthi isixhumi sivikelwe ngokuphelele ekungeneni kothuli ("6": "siqinile uthuli") futhi sivikelwe emiphumeleni yokucwiliswa okwesikhashana emanzini phakathi kuka-15cm no-1 imitha ukujula. Ukuhlolwa kwe-IPX7 kuhilela ukucwilisa isampula yokuhlola emanzini ekujuleni kwemitha eli-1 imizuzu engama-30. Lesi silinganiso sifanele izixhumi ezingase zibe ngaphansi kwezikhukhula zesikhashana noma ukucwiliswa ngengozi, kodwa asibaleli amanzi ashisa kakhulu noma ukuchayeka emanzini anomfutho ophezulu.

I-IP69K iyisilinganiso sokuvikelwa esiphezulu kakhulu ohlelweni lwe-IEC 60529 futhi yasungulwa ekuqaleni kwemishini yokucubungula ukudla edinga ukuhlanza njalo ngokucindezela okuphezulu kanye nokushisa okuphezulu. Ukuhlolwa kwe-IP69K kuhilela ukufuthwa kwamanzi ngokucindezela okungu-116 kuya ku-145 PSI (8-10 MPa) kusuka kuma-engeli amane (0, 30, 60, 90 degrees) ngesilinganiso sokugeleza esingamalitha ayi-14-16 ngomzuzu, kanti izinga lokushisa lamanzi lingu-80C. Ezindaweni ezivalekile zangaphandle, i-IP69K ivame ukucaciswa kuphela ezisetshenzisweni lapho izixhumi zizogezwa ngokucindezela njengengxenye yokuhlanza imishini njalo - isibonelo, ezitshalweni zokucubungula ukudla neziphuzo, noma ezindaweni zokuhlanza amanzi angcolile lapho ukuhlanzeka kwendawo evalekile kubalulekile khona.

Empeleni, kwikhabhinethi evamile yokulawula yangaphandle endaweni engadingi ukucubungula ukudla, i-IP55 ngokuvamile yanele ukuchayeka emvuleni evamile kanye nokuchayeka emanzini, kuyilapho i-IP67 iba yinto efanele uma ukufakwa kusendaweni evame ukukhukhulwa yizikhukhula, ezingeni noma ngaphansi kwebanga, noma endaweni lapho amanzi ahlangana khona eduze kwesisekelo sendawo evalekile kuyingozi eyaziwayo. Isinqumo phakathi kwe-IP55 ne-IP67 kufanele siqhutshwe ukuhlolwa kwengozi ethile endaweni ethile okucabangela amaphethini emvula endawo, ukuphakama kokufakwa kwe-enclosure, izimo zokukhipha amanzi eduze kwendawo yokufaka, kanye nomphumela wokwehluleka kwesixhumi ekusebenzeni kwesistimu iyonke.

Uhlu Lokuhlola Lokukhetha Okusebenzayo Lwezixhumi ze-M12 Ezindaweni Zangaphandle

Ngemva kokusebenza ngamashidi amaningi okucacisa kanye nezincwadi zokufaka, ngihlukanise izindlela zokuhlola ezibalulekile zaba uhlu lokuhlola olusebenzayo engiluncoma kubo bonke onjiniyela abachaza izixhumi ze-M12 zokusetshenziswa ngaphandle. Lokhu akusikho indawo yokubuyekezwa okuphelele kobunjiniyela, kodwa kuyindawo yokuqala ehlanganisa izici ezivame ukunganakwa.

Okokuqala, qinisekisa ukuthi ilungiselelo lokubhala ikhodi kanye nokuxhumana lihambisana nohlelo lwakho lokusebenza. Njengoba kuphawuliwe ngaphambili, i-A-coded 4-pin iyona evame kakhulu kuzinhlelo zokusebenza zamandla kanye nesignali ye-DC. I-B-coded 5-pin isetshenziselwa amaphrothokholi e-fieldbus. Izibambo ze-D-coded 4-pin ze-100M Ethernet. Izibambo ze-X-coded 8-pin ze-gigabit Ethernet. Ukusebenzisa uhlobo lwekhodi olungalungile kungabangela ukungahambisani komshini esibonakalayo sokuxhumanisa, okungaphoqa abafaki ukuthi basebenzise ama-adapter noma, okubi nakakhulu, ukuguqula isixhumi ensimini - kokubili okuphazamisa ukusebenza kokuvala.

Okwesibili, qinisekisa ukuthi impahla yokuhlala ifanele indawo yakho yokufaka. Izinto zokuhlala ezivame kakhulu zezixhumi ze-M12 yi-polyamide (PA, eyaziwa kakhulu ngokuthi i-nylon) kanye nensimbi engagqwali. Izixhumi ze-polyamide zilula, ziyasebenza kahle, futhi zinikeza ukumelana okuhle kwamakhemikhali kumakhemikhali amaningi kanye namafutha ezimboni. Kodwa-ke, i-PA isengozini yokuwohloka kwe-UV ngokuhamba kwesikhathi uma ivezwa elangeni eliqondile, okungabangela ukuqhekeka kanye nokuqhekeka endaweni yokuvala ngemuva kweminyaka engu-3-5 yokuchayeka ngaphandle. Ekufakweni kwesikhathi eside ngaphandle, chaza izindlu ze-PA ezizinzile ze-UV noma zensimbi engagqwali (AISI 303 noma 316). Izixhumi zensimbi engagqwali zibiza iprimiyamu enkulu yentengo - ngokuvamile izindleko eziphindwe kathathu kuya kahlanu kune-PA - kodwa impilo yesevisi ende ezindaweni ezivezwe yi-UV ivame ukufaneleka ekutshalweni kwezimali.

Okwesithathu, hlola ukwakheka kwe-clamp yekhebula. Indawo yokungena yekhebula ivame ukuba yisixhumanisi esibuthakathaka kakhulu ekuhlanganisweni kwesixhumi se-M12. Izixhumi ezine-clamp yekhebula ezihlanganisiwe ezisebenzisa i-compression fitting noma indlela yokubopha efakwe entwasahlobo zinikeza ukumelana okungcono kokudonsa ikhebula kanye nokuvala okungcono endaweni yokungena yekhebula kunezixhumi ezinezihlangu ezilula zokukhulula ukucindezeleka. Lokhu kubaluleke kakhulu ekufakweni kwangaphandle lapho izintambo zivezwa khona ekujikelezeni kokushisa, ukunyakaza okubangelwa umoya, kanye nokucindezeleka okungenzeka komshini ngenxa yokubanjwa kwekhebula ngengozi.

Okwesine, hlola izinga lokushisa lokusebenza. Izixhumi ezijwayelekile ze-M12 ezinezindlu ze-PA zivame ukuba nezinga lokushisa lokusebenza elisukela ku--25C kuya ku-+85C. Izinguqulo zezinga lokushisa elandayo (ngokuvamile -40C kuya ku-+105C) zisebenzisa izinto zokwakha ezahlukene kanye nezinhlanganisela zokuvala futhi zifanelekile ukufakwa ezimweni zezulu ezinokushintshashintsha okukhulu kwezinga lokushisa noma ezindaweni ezivalekile ezifakwe elangeni eliqondile lapho izinga lokushisa langaphakathi lingadlula khona indawo ngo-15-20C. Emakhabetheni angaphandle enkabeni yeShayina, lapho izinga lokushisa lasehlobo lingafinyelela ku-40C ezindaweni ezivalekile kanye nezimnyama elangeni eliqondile lingafinyelela izinga lokushisa langaphakathi elingu-60C noma ngaphezulu, ukucacisa izixhumi ezinezinga lokushisa elandayo akuyona into ongayikhetha - kubalulekile.

Indlela Yokuqinisekisa Amadokhumenti Esitifiketi Ngaphambi Kokuthenga

Lesi yisinyathelo esishiywa kaningi kunalokho okufanele, futhi siyimbangela eyinhloko yokwehluleka okuningi kwesixhumi engikuhlolile. Amaqembu okuthenga amukela isimangalo seshidi ledatha esithi "IP67 elinganiswe ngokwe-IEC 61076-2-101" njengesiqinisekiso esanele, ngaphandle kokucela umbiko wokuhlolwa wangempela noma isitifiketi. Lokhu kuyiphutha ngoba isimangalo seshidi ledatha siyisitatimende sokumaketha, hhayi idokhumenti yokuqinisekisa ikhwalithi.

Uma ngifanelekela umhlinzeki omusha wesixhumi se-M12, ngicela imibhalo emithathu: umbiko wokuhlolwa ovela elabhorethri egunyaziwe yenkampani yangaphandle (njenge-TUV, i-UL, noma inhlangano yokuhlola eqinisekisiwe ye-IEC 60529 efanayo) eqinisekisa ukuthi isilinganiso se-IP siqinisekiswe ngaphansi kwezimo zokuhlola ezijwayelekile, idatha yomkhiqizi uqobo yokulawula ikhwalithi yokukhiqiza ekhombisa ukuthi ama-connectors ayi-100% ahlolwa ukusebenza kokuvala ngesikhathi sokukhiqiza (hhayi nje ukuhlolwa kwesihloko sokuqala), kanye neshidi ledatha lezinto zokwakha eziqinisekisa ukuthi isithasiselo sokuzinza kwe-UV sifakiwe ekwakhiweni kwezinto.

Ngokuhluleka kwebhokisi le-solar farm combiner engikhulume ngalo ekuqaleni kwalesi sihloko, ishidi ledatha lomhlinzeki wesixhumi libike ukusebenza kwe-IP67. Umbiko wokuhlola ukhombisile ukuthi i-IP67 iqinisekisiwe — kodwa kusampula yezixhumi ezintathu, ezihlolwe ngaphansi kwezimo ezifanele zelebhu, zisesimweni esisha. Kwakungekho datha yokuhlola umkhiqizo, akukho datha yokuguga kwe-UV, futhi akukho datha yokuhlola yokukhipha ngomshini. Ngemva kweminyaka emibili yokuchayeka ensimini, i-silicone sealing gasket esitsheni sokufaka iphaneli yayisiqalile ukonakala ngenxa yokuchayeka kwe-UV, futhi isivalo esisebenzayo sase sinciphile kusukela ku-IP67 kuya cishe ku-IP54. Isiphepho asizange sibangele ukwehluleka okusha — sembule ukuwohloka okwakukhona kakade obekuqongelela izinyanga.

Imikhuba Yokufaka Enquma Ukusebenza Kwensimu

Ngisho nesixhumi se-M12 esingcono kakhulu sizohluleka ensimini uma singafakwanga kahle. Ngifuna ukugqamisa amaphutha okufaka avame kakhulu engiwabonayo nokuthi ngenzeni esikhundleni salokho.

Iphutha lokuqala nelivame kakhulu i-torque engalungile endleleni yokukhiya izikulufo. Izinga le-IEC 61076-2-101 licacisa i-torque yokuhlanganisa enconywayo — ngokuvamile engu-0.4 kuya ku-0.6 Nm yezixhumi ezinezintambo ze-M12 — elinganisela ukusebenza kokugcinwa komshini ngokumelene nengozi yokulimaza isikhombimsebenzisi sokuvala. Ukufaka i-torque ngaphansi kwe-torque kudala uphawu olungazinzile ngokomshini futhi olusengozini yokuxega ngenxa yokudlidliza. Ukufaka i-torque ngokweqile kungacindezela futhi kulimaze i-O-ring noma i-gasket yokuvala, okonakalisa unomphela ukusebenza kokuvala. Empeleni, ngincoma ukusebenzisa i-torque wrench noma i-torque-limiting driver esethwe enanini le-torque elicacisiwe lomenzi, kunokuthembela "ekuqiniseni ngesandla kanye nokujika kwekota."

Iphutha lesibili elivamile ukujula okungafanele kokukhwezwa kwephaneli. Uma isixhumi se-M12 sifakwe odongeni oluvalekile, ukujiya kodonga oluvalekile kuthinta ukujula kokukhwezwa kwentambo yesixhumi. Uma iphaneli lincane kakhulu, ukukhwezwa kwentambo kungase kungabi ngokwanele ukumelana namandla okudonsa alinganisiwe. Uma iphaneli lilikhulu kakhulu, umzimba wesixhumi ungase uphume phansi ngaphambi kokuba ubuso bokuvala buthinte ngokuphelele indawo evalekile. Abakhiqizi abaningi bachaza ububanzi obuncane nobuphezulu bobukhulu bephaneli yezitsha zabo zokukhwezwa kwephaneli - ngokuvamile kusuka ku-1.5mm kuya ku-4mm ezinguqulweni ezijwayelekile. Ukusebenzisa ukujiya kwephaneli ngaphandle kwalolu hlu ngaphandle kokubonisana nomkhiqizi kungabangela ukwehluleka kwesivalo okungabonakali ngesikhathi sokufakwa futhi kubonakale kuphela ngemva kwemvula yokuqala.

Iphutha lesithathu ukusebenzisa uhlobo lwekhebula olungalungile. Izixhumi ze-M12 zenzelwe ukusetshenziswa ngobubanzi bekhebula kanye nezinhlobo zokwakha ezithile. Ukusebenzisa ikhebula elinobubanzi bangaphandle obuncane kunobubanzi bekhebula lesixhumi kuzoholela ekubambeni okuxegayo okunganikezi ukuvala okwanele noma ukukhululeka kokucindezeleka. Ukusebenzisa ikhebula elikhulu kakhulu ngeke lilingane noma lizodinga amandla amaningi angalimaza umzimba wesixhumi noma ijakethi yekhebula ngesikhathi sokuhlanganiswa. Njalo qinisekisa ububanzi bobubanzi bekhebula obuchazwe umenzi wesixhumi bese uqinisekisa ukuthi ukwakhiwa kwekhebula lakho lasensimini (umucu owodwa vs. ovalelwe, ijakethi ye-PVC vs. PUR, evikelwe vs. engavikelwe) kuyahambisana nomklamo wesixhumi.

Izinqubo Zokulungisa Ezandisa Impilo Yesevisi Yesixhumi

Ngokufaka izivalo zokulawula zangaphandle, ngincoma ukusungula inqubo yokulungisa yokuvimbela ehlanganisa ukuhlolwa njalo kwazo zonke izixhumi ze-M12. Imvamisa incike ebunzimeni bemvelo bendawo yokufaka, kodwa ezivaloni eziningi zangaphandle ezindaweni ezinesimo sezulu esishisayo noma sezulu semvula, ukuhlolwa kwaminyaka yonke ngesikhathi sesomiso kufanelekile.

Uhlu lokuhlola kufanele lufake ukuhlolwa okubonakalayo kwendlu yesixhumi ukuze kutholakale izimpawu zokuwohloka kwe-UV (ukuqhekeka, ukushova, ukushintsha kombala), ukuqinisekisa ukuthi indlela yokukhiya izikulufo isesenani le-torque elibekiwe (kusetshenziswa i-torque wrench, hhayi ngokuzizwa), ukuhlolwa kwendawo yokungena kwekhebula ukuze kutholakale izimpawu zokuwohloka kwejakethi noma ukungena komswakama ekhebulani, kanye nokuqinisekisa ukuthi ubuso bokuvala bezixhumi zephaneli buhlanzekile futhi abunazo imfucumfucu, i-sealant endala, noma imikhiqizo yokugqwala engase iphazamise isikhombimsebenzisi sesivalo.

Icebiso elilodwa elisebenzayo lokulungisa: faka ucezu oluncane lwegrisi ye-dielectric ye-silicone ebusweni bokuvala izixhumi ze-M12 ngaphambi kokuhlangana. Lokhu kufeza izinjongo ezimbili. Okokuqala, kunikeza isithiyo esengeziwe ekungeneni komswakama esibonakalayo sesixhumi. Okwesibili, kusebenza njengesithambisi ngesikhathi sokuhlangana, okwenza kube lula ukufeza i-torque efanele ngaphandle kokufaka ukucindezeleka okwengeziwe ezintweni zokuvala. Sebenzisa igrisi ye-dielectric eyenzelwe ngqo izixhumi zikagesi - igrisi yezimoto ejwayelekile ingahlasela ezinye izinto zokuhlala futhi ingalimaza izinto zokuvala zerabha ngokuhamba kwesikhathi.
