Izihlanganisi ezingangeni manzi ze-M12 Thread Pass IP55 zoFakelo lwe-Outdoor Control Enclosure

Kwiminyaka emithathu eyadlulayo, ndafumana umnxeba oxhalabileyo ovela kumqhubi wefama yelanga kwiPhondo laseJiangsu. Inkqubo yakhe ye-SCADA yayingasebenzi ngexesha lemvula enkulu. Indawo yokulawula kwenye yeebhokisi zokudibanisa yayivuza, kwaye iindibano zesixhumi se-M8 ngaphakathi zasilela. Iiyure ezingamashumi amane anesibhozo zokungasebenzi, iqela lenkonzo yasentsimini labantu abathandathu, kunye nesiqendu sesohlwayo esibalulekileyo esivela kumqhubi wegridi kamva, wandibuza umbuzo ebendiwuva ngeendlela ezahlukeneyo ukusukela ngoko: "Ndingaqinisekisa njani ukuba oku akuphinde kwenzeke kwakhona?" Impendulo, njengoko ndamchazela ngoko kwaye njengoko ndiza kuchaza kweli nqaku, ayikho nje ekukhetheni umlinganiselo we-IP ofanelekileyo wendawo yakho yokuvala, kodwa ekuqondeni indlela iinkcukacha zesixhumi - ingakumbi umgangatho wesixhumi esingangeni manzi we-M12 - ezisebenzisana ngayo noyilo lwenkqubo yakho iyonke, iindlela zakho zokufaka, kunye neenkqubo zakho zokulungisa.

Emva kokusebenza nabafaki be-automation yemizi-mveliso kunye nabakhi bombane kwiindawo ezininzi zokufakelwa ngaphandle - iifama zelanga, iibhokisi zolawulo lwe-wind turbine, iikhabhathi zesignali zendlela, iinkqubo zokulawula izibane zangaphandle, kunye neendawo zokuvala izityalo zonyango lwamanzi - ndiye ndayila umfanekiso ocacileyo wendawo apho iinkcukacha zesixhumi se-M12 ziqondwa ngokuchanekileyo khona kunye nendawo apho zitolikwa gwenxa khona ngokucwangcisiweyo. Iindaba ezimnandi zezokuba izixhumi ze-M12 ezihlangabezana ne-IEC 61076-2-101 ziphakathi kwezona zinto zithembekileyo zokunxibelelana ezikhoyo zokusetyenziswa ngaphandle kwemizi-mveliso. Iindaba ezimbi zezokuba "ukudibana ne-IP55" kwiphepha ledatha akuthethi ngokuzenzekelayo ukuba "kuya kuhlala iminyaka emihlanu kwikhabhathi esecaleni kwendlela kwiPhondo laseGuangdong ngexesha le-typhoon" ukuba isixhumi asichazwanga ngokuchanekileyo, asifakwanga, kwaye asigcinwanga.

Kweli nqaku, ndiza kuhamba ngomgangatho wobuchwephesha ochaza ukusebenza kwesixhumi se-M12, ndichaze ukuba ithetha ukuthini i-IP55 kunye neereyithingi eziphezulu ngokwemigaqo esebenzayo, ndibonelele ngesakhelo sokukhetha esichaza iimeko zokufakelwa kwehlabathi lokwenyani, kwaye ndabelane ngoko ndikufundileyo kwiimpazamo - kuquka ibhokisi yokudibanisa ifama yelanga eyaqala le ngxoxo.

Kutheni Ukuvuza Kwakho Kwangaphandle Kunokuba Yingxaki Yokuqhagamshela

Mandiqale ngengcamango ephosakeleyo endiyifumanisa phantse kuzo zonke iinkcazo zovavanyo emva kokufa endizenzayo malunga nokusilela kokungena kwamanzi kwindawo evalekileyo: ingcinga yokuba indawo evalekileyo ngokwayo ayiphumelelanga. Kwiimeko ezininzi endiphanda ngazo, i-gasket yendawo evalekileyo ayiphelelanga. Indawo yokungena kwamanzi ikwiindawo zokungena kwintambo - ngakumbi kwindawo yokudibanisa ukuya kwindawo evalekileyo nakwindawo yokudibanisa ukuya kwisixhobo. Yiyo kanye le nto isixhumi esichaziweyo nesifakwe ngokuchanekileyo sidla ngokuba sesona sixhobo sibalulekileyo sokuthintela amanzi kuyo yonke indawo evalekileyo.

Xa ndandityelele elo famu yelanga eJiangsu, ibhokisi yokudibanisa yayine-IP65 yodwa. I-gasket ejikeleze ucango yayiphelele. Umsele womoya wawucocekile. Kodwa ii-cable glands apho iintambo zasentsimini zazingena khona ebhokisini yayizii-cable glands ze-nylon eziqhelekileyo ezingenazo ezinye ii-washers zokuvala, kwaye izihlanganisi ezibunjiweyo kwangaphambili kwiintambo ze-sensor zazihleli kwi-receptacle yephaneli enesitywina se-O-ring esisisiseko kuphela. Ngexesha lenkanyamba, imvula eqhutywa ngumoya yanyanzeliswa ukuba ingene kwii-receptacle zephaneli ngesenzo se-capillary, kwaye ukusuka apho yangena ngaphakathi kwe-enclosure. I-enclosure ngokwayo yayilungile. Izihlanganisi zazilikhonkco elibuthathaka.

Le ndlela iphindaphinda kuzo zonke iintlobo zofakelo. Ndibone indlela efanayo yokusilela kwiikhabhathi zemiqondiso yendlela eFujian (apho iimvula zemvula zibangela iimeko ezihlala ziphezulu zomswakama), kwiibhokisi zolawulo lwezityalo zonyango eShandong (apho ukufuma ngenxa yokujikeleza kobushushu kudibana nokuvezwa kwe-splash), nakwiindawo zokuvalela izikhululo zokutshaja ze-EV eZhejiang (apho ukuhlamba ngoxinzelelo lokucoca kudala ukuvezwa kwamanzi okwethutyana oxinzelelo oluphezulu). Kuzo zonke iimeko, isixhumi yayiyindawo yokuqala yokusilela - hayi indawo evalekileyo.

Ukuqonda i-IEC 61076-2-101: Umgangatho ochaza ukusebenza kwe-M12

Ukuba uchaza izihlanganisi ze-M12 kwizicelo zangaphandle kwimizi-mveliso, kufuneka uqonde ukuba umgangatho we-IEC 61076-2-101 ugubungela ntoni na, kwaye okubaluleke ngokulinganayo, oko ungakuqinisekisiyo. Lo mgangatho, obizwa ngokuba "Izihlanganisi zezixhobo ze-elektroniki — Icandelo 2-101: Izihlanganisi ezijikelezayo — Iinkcukacha zeenkcukacha zezihlanganisi ze-M12 ezine-screw-locking," luxwebhu olusisiseko oluchaza ubukhulu boomatshini, ulungiselelo loqhagamshelwano, kunye neemfuno zokusebenza kwezihlanganisi ze-M12 ezisetyenziswa kwizicelo zokwenza izinto ngokuzenzekelayo kunye nolawulo kwimizi-mveliso.

Umgangatho uchaza iimpawu ezibalulekileyo ekufuneka amaqela okuthenga kunye neenjineli bazihlole ngononophelo. Okokuqala, ucacisa indlela yokutshixa: Izihlanganisi ze-M12 zisebenzisa uyilo lokutshixa ngezikrufu olunomsonto wesilisa emzimbeni wesihlanganisi olutshixa lungena kumngxuma wephaneli enemisonto yabasetyhini, okanye indlela yokutshixa ngesikrufu. Uhlobo lokutshixa ngezikrufu yinto abantu abaninzi abayithethayo xa besithi "isihlanganisi esinemisonto ye-M12," kwaye luyilo olubonelela ngokusebenza okuthembekileyo kokutywina kwiindawo zangaphandle. Umsonto wesikrufu udala isitywina sesinyithi-ukusuka kwisinyithi okanye sesinyithi-ukusuka kwipolymer esingamelaniyo nokukhululeka okubangelwa kukungcangcazela - imfuneko ebalulekileyo kuyo nayiphi na indlela apho kukho ukujikeleza kobushushu okanye ukungcangcazela koomatshini.

Okwesibini, umgangatho uchaza amalungiselelo oqhagamshelwano. Eyona ixhaphakileyo kwii-sensor zemizi-mveliso kunye noqhagamshelwano lwe-actuator yi-A-coded (4-pins kwi-DC sensors kunye namandla), i-B-coded (5-pins kwi-Fieldbus Foundation kunye ne-Profibus), kunye ne-D-coded (4-pins kwi-100M Ethernet). Kwii-applications zangaphandle eziquka ukusasazwa kwamandla kunye nesignali, ulungiselelo lwe-A-coded 4-pin lolona lusetyenziswa kakhulu, ludla ngokulinganiselwa kwi-250V AC okanye i-250V DC kunye ne-4A continuous current ngoqhagamshelwano ngalunye. Izihlanganisi ze-X-coded (8-pin, ezisetyenziselwa i-gigabit Ethernet) ziya zixhaphaka ngakumbi kwi-applications ze-smart enclosure apho kufuneka unxibelelwano lwedatha olukhawulezayo kunye namandla.

Okwesithathu, kwaye le yinxalenye ebaluleke kakhulu kwizicelo ze-IP55 zangaphandle: I-IEC 61076-2-101 ichaza inqanaba lokhuseleko lwe-IP elilinganisiweyo ngokusekelwe kuyilo lwesixhumi kunye nolwakhiwo lokutywina. Nangona kunjalo, umgangatho uchaza iimeko zovavanyo — ezihlala zenziwa phantsi kweemeko zelebhu ezilawulwayo ezinezixhumi ezicocekileyo kunye namaxabiso e-torque athile — ezingabonisi ngokuyimfuneko iimeko zofakelo lwangaphandle lokwenyani kwiinyanga ezintandathu emva kokuba isixhumi sichatshazelwe yimitha ye-UV, ukujikeleza kobushushu, kunye noxinzelelo loomatshini lokufakelwa kwentsimi.

Eli nqaku lokugqibela libalulekile. Xa umenzi esithi "IP67 ilinganiswe ngokwe-IEC 61076-2-101," into abayibangayo kukuba isixhumi esitsha, esicocekileyo, esidityaniswe ngokufanelekileyo ngokwemiyalelo yokufakela, siphumelele uvavanyo lwe-IP67 phantsi kweemeko zelebhu. Ukusebenza kwelo qhagamshelo emva kweminyaka emibini yokuvezwa ngaphandle kuxhomekeke ngokupheleleyo kwizinto ezingaphandle komgangatho: ukuzinza kwe-UV kwezinto zokuhlala, ukungafani kokwanda kobushushu phakathi komzimba wesixhumi kunye nephaneli yokuqhoboshela, ukugcinwa kwe-torque yendlela yokutshixa izikrufu, kunye nomgangatho woyilo lwe-cable clamp oluthintela ukutsalwa kwentambo ekudluliseni uxinzelelo kwisitywina.

IP55, IP67, kunye ne-IP69K: Oko Kuthethwa Ngamanani Ngokwenyani Kwifakelo Lakho

Inkqubo yokulinganisa i-IP (Ingress Protection) ichazwa yi-IEC 60529 kwaye inika indlela emiselweyo yokuchaza inqanaba lokhuseleko olunikezelwa ziindawo zombane ezivalekileyo kwizinto eziqinileyo kunye nolwelo. Uvavanyo lunamanani amabini: elokuqala libonisa ukhuseleko kwizinto eziqinileyo (0-6), kwaye elesibini libonisa ukhuseleko kwizinto ezimanzi (0-9K).

Kwizicelo zokudibanisa izixhobo zokulawula ngaphandle, amanqaku amathathu oza kudibana nawo rhoqo yi-IP55, i-IP67, kunye ne-IP69K. Ukuqonda oko kuqinisekiswa linqanaba ngalinye kunye noko lingakuqinisekisiyo kubalulekile ekwenzeni ukhetho olufanelekileyo.

I-IP55 ithetha ukuba isixhumi sikhuselekile ekungeneni kothuli okulinganiselweyo (umlinganiselo "5": "sikhuselekile eluthulini" — ukungena kothuli akuthintelwanga ngokupheleleyo, kodwa asingeni ngobuninzi obaneleyo ukuphazamisa ukusebenza okwanelisayo) kwaye sikhuselekile ekungeneni kwamanzi kwiijethi zamanzi ezivela nakweyiphi na indlela (u "5" emva kuka "x" wokukhusela ulwelo). Uvavanyo lwejethi yamanzi lwe-IPX5 lusebenzisa i-nozzle ene-orifice ye-6.3mm, itshiza amanzi ngesantya sokuhamba seelitha ezili-12.5 ngomzuzu kuxinzelelo lwe-30 kPa ukusuka kumgama weemitha ezi-3. Oku kulinganisa ukuvezwa kwemvula okanye ukuchaphaza kodwa akulinganisi ukuntywiliselwa okanye ukuhlamba ngoxinzelelo oluphezulu.

I-IP67 ithetha ukuba isixhumi sikhuselekile ngokupheleleyo ekungeneni kothuli ("6": "siqinile eluthulini") kwaye sikhuselekile kwimiphumo yokuntywiliselwa okwethutyana emanzini phakathi kwe-15cm kunye nobunzulu bemitha e-1. Uvavanyo lwe-IPX7 lubandakanya ukuntywiliselwa kwesampulu yovavanyo emanzini kubunzulu bemitha e-1 imizuzu engama-30. Olu vavanyo lufanelekile kwizixhumi ezinokuba phantsi kwezikhukula okwethutyana okanye ukuntywiliselwa ngengozi, kodwa alubaleli amanzi ashushu kakhulu okanye ukuvezwa kwamanzi ngoxinzelelo oluphezulu.

I-IP69K yeyona ndlela iphezulu yokukhusela kwinkqubo ye-IEC 60529 kwaye yaqalwa yenzelwe izixhobo zokulungisa ukutya ezifuna ukuhlamba rhoqo ngoxinzelelo oluphezulu kunye nobushushu obuphezulu. Uvavanyo lwe-IP69K lubandakanya ukutshiza ngamanzi kuxinzelelo lwe-116 ukuya kwi-145 PSI (8-10 MPa) ukusuka kwii-engile ezine (0, 30, 60, 90 degrees) ngesantya sokuhamba seelitha ezili-14-16 ngomzuzu, kunye nobushushu bamanzi kwi-80C. Kwiindawo zokuvala zangaphandle, i-IP69K idla ngokuchazwa kuphela kwiindawo zokusetyenziswa apho izihlanganisi ziya kuhlamba ngoxinzelelo njengenxalenye yokucoca izixhobo rhoqo - umzekelo, kwiindawo zokucoca ukutya neziselo, okanye kwiindawo zokucoca amanzi amdaka apho ucoceko lweendawo zokuvala lubalulekile.

Enyanisweni, kwikhabhathi eqhelekileyo yokulawula ngaphandle kwindawo engeyiyo eyokulungisa ukutya, i-IP55 iqhelekile ukuba imvula eqhelekileyo kunye nokuvezwa kwe-splash, ngelixa i-IP67 iba yinto efanelekileyo ukuba ukufakelwa kukwindawo enokukhukuliswa zizikhukula, kwinqanaba okanye ngaphantsi kwenqanaba, okanye kwindawo apho amanzi ajikeleze isiseko sendawo ebiyelweyo kuyingozi eyaziwayo. Isigqibo phakathi kwe-IP55 kunye ne-IP67 kufuneka siqhutywe luvavanyo lomngcipheko olujoliswe kwindawo ethile oluqwalasela iipateni zemvula zasekuhlaleni, ukuphakama kokufakwa kwendawo ebiyelweyo, iimeko zokukhupha amanzi ezijikeleze indawo efakelweyo, kunye nesiphumo sokungaphumeleli kwesixhumi ekusebenzeni kwenkqubo iyonke.

Uluhlu Lokujonga Olusebenzayo Lwee-M12 Connectors Kwii-Enclosures Zangaphandle

Emva kokusebenza kwiincwadana ezininzi zeenkcukacha kunye neencwadi zokufaka, ndizihlalutyile iikhrayitheriya zovavanyo ezibalulekileyo ndaza ndazibeka kuluhlu lokuhlola olusebenzayo endilucebisayo kuyo yonke injineli echaza izihlanganisi ze-M12 zokusetyenziswa ngaphandle. Oku akuthathi indawo yophononongo olupheleleyo lobunjineli, kodwa yindawo yokuqala egubungela izinto eziqhele ukujongwa.

Okokuqala, qinisekisa ukuba ikhowudi kunye nolungiselelo loqhagamshelwano luhambelana nesicelo sakho. Njengoko kuphawuliwe ngaphambili, i-A-coded 4-pin yeyona ixhaphakileyo kwizicelo zamandla kunye nesignali yeDC. I-B-coded 5-pin isetyenziselwa iiprotokholi ze-fieldbus. Izibambo ze-D-coded 4-pin ze-100M Ethernet. Izibambo ze-X-coded 8-pin ze-gigabit Ethernet zinokubangela ukungahambelani koomatshini kwi-interface yokudibana, okunokunyanzela abafaki ukuba basebenzise ii-adapters okanye, okubi ngakumbi, batshintshe isixhumi esisentsimini - zombini ezi zinto zibeka emngciphekweni ukusebenza kokutywina.

Okwesibini, qinisekisa ukuba izinto zokwakha zifanelekile kwindawo yakho yokufakela. Izinto zokwakha eziqhelekileyo kwizihlanganisi ze-M12 yi-polyamide (PA, eyaziwa ngokuba yi-nylon) kunye nentsimbi engatyiwayo. Iindlu ze-polyamide zilula, zingabizi kakhulu, kwaye zibonelela ngokumelana okuhle kweekhemikhali kwiinyibilikisi ezininzi kunye neeoyile zoshishino. Nangona kunjalo, i-PA isengozini yokuwohloka kwe-UV ngokuhamba kwexesha xa ivezwa elangeni ngqo, okunokubangela ukuqhekeka kunye nokuqhekeka kwindawo yokuvala emva kweminyaka emi-3-5 yokuvezwa ngaphandle. Kwiifektri zangaphandle ixesha elide, chaza izindlu ze-PA ezizinzisiweyo ze-UV okanye zentsimbi engatyiwayo (AISI 303 okanye 316). Izihlanganisi zentsimbi engatyiwayo zibiza ixabiso eliphakamileyo - ngesiqhelo ixabiso eliphindwe kathathu ukuya kahlanu kune-PA - kodwa ubomi benkonzo obude kwiindawo ezivezwe yi-UV budla ngokuthethelela utyalo-mali.

Okwesithathu, jonga uyilo lwe-cable clamp. Indawo yokungena yentambo idla ngokuba yeyona khonkco libuthathaka kwi-M12 connector assembly. Izihlanganisi ezinee-cable clamps ezidityanisiweyo ezisebenzisa i-compression fitting okanye i-spring-loaded clamping mechanism zibonelela ngokumelana okungcono kokutsalwa kwentambo kunye nokutywinwa okungcono kwindawo yokungena yentambo kunezihlanganisi ezineebhutsi ezilula zokunciphisa uxinzelelo. Oku kubaluleke kakhulu kwiindawo zangaphandle apho iintambo zichaphazeleka kukujikeleza kobushushu, intshukumo ebangelwa ngumoya, kunye noxinzelelo olunokwenzeka loomatshini oluvela ekubambekeni kwentambo ngengozi.

Okwesine, jonga uluhlu lobushushu bokusebenza. Izihlanganisi ze-M12 eziqhelekileyo ezinee-PA housings zihlala zinoluhlu lobushushu bokusebenza oluphakathi kwe--25C ukuya kwi-+85C. Iinguqulelo zohlobo lobushushu olude (ngesiqhelo -40C ukuya kwi-+105C) zisebenzisa izixhobo ezahlukeneyo zezindlu kunye neekhompawundi zokutywina kwaye zifanelekile ukufakwa kwiindawo ezinemozulu enotshintsho olukhulu lobushushu okanye kwiindawo ezivalekileyo ezifakwe elangeni ngqo apho ubushushu bangaphakathi bunokudlula kwi-15-20C. Kwiikhabhathi zangaphandle kumbindi weTshayina, apho ubushushu behlobo bunokufikelela kwi-40C kwiindawo ezivalekileyo kunye neendawo ezimnyama elangeni ngqo bunokufikelela kubushushu bangaphakathi be-60C nangaphezulu, ukucacisa izihlanganisi ezinoluhlu lobushushu olude akunyanzelekanga - kubalulekile.

Indlela Yokuqinisekisa Amaxwebhu Esiqinisekiso Ngaphambi Kokuba Uthenge

Eli linyathelo eliyekiswa rhoqo kunokuba kufanele ukuba linjalo, kwaye yimbangela eyintloko yokusilela kwezixhobo ezininzi endiziphandile. Amaqela okuthenga ayamkela ibango ledatha elithi "IP67 elinganiswe ngokwe-IEC 61076-2-101" njengesiqinisekiso esaneleyo, ngaphandle kokucela ingxelo yovavanyo okanye isatifikethi sokwenyani. Le yimpazamo kuba ibango ledatha yingxelo yokuthengisa, ayiloxwebhu lokuqinisekisa umgangatho.

Xa ndifanelekela umthengisi omtsha we-M12 connector, ndicela amaxwebhu amathathu: ingxelo yovavanyo kwilebhu yomntu wesithathu evunyiweyo (njenge-TUV, i-UL, okanye iqumrhu lovavanyo elivunyiweyo le-IEC 60529) eliqinisekisa ukuba umlinganiselo we-IP uqinisekisiwe phantsi kweemeko zovavanyo eziqhelekileyo, idatha yomenzi ngokwakhe yolawulo lomgangatho wemveliso ebonisa ukuba i-100% yezixhumi zivavanywa ukusebenza kokutywina ngexesha lokwenziwa (hayi nje ukuhlolwa kwenqaku lokuqala), kunye nephepha ledatha yezinto zokwakha eziqinisekisa ukuba isongezo sokuzinzisa i-UV sifakiwe kwifomyula yezinto.

Ngokuphathelele ukusilela kwebhokisi yokudibanisa ifama yelanga endikukhankanyileyo ekuqaleni kweli nqaku, iphepha ledatha lomthengisi wesixhumi libonise ukusebenza kwe-IP67. Ingxelo yovavanyo ibonise ukuba i-IP67 iqinisekisiwe — kodwa kwisampulu yezixhumi ezintathu, ezivavanywe phantsi kweemeko ezifanelekileyo zelebhu, zikwimeko entsha. Akukho datha yovavanyo lwemveliso, akukho datha yokuguga kwe-UV, kwaye akukho datha yovavanyo lokutsalwa koomatshini. Emva kweminyaka emibini yokuvezwa ebaleni, i-silicone sealing gasket kwi-receptacle yephaneli yayiqalile ukonakala ngenxa yokuvezwa yi-UV, kwaye isitywino esisebenzayo sonakaliswe ukusuka kwi-IP67 ukuya kwi-IP54. Inkanyamba ayizange ibangele ukungaphumeleli okutsha — ityhile ukonakala okwakusele kukho kangangeenyanga.

Iindlela zoFakelo ezichonga ukusebenza kwentsimi

Nesixhumi se-M12 esingcono kakhulu siya kusilela ukuba asifakwanga kakuhle. Ndifuna ukugxininisa ezona mpazamo zixhaphakileyo zokufakelwa endizibonayo kunye nento endifanele ndiyenze endaweni yoko.

Impazamo yokuqala neyona ixhaphakileyo yi-torque engachanekanga kwindlela yokutshixa izikrufu. Umgangatho we-IEC 61076-2-101 ucacisa i-torque yokudibana ecetyiswayo — ngesiqhelo i-0.4 ukuya kwi-0.6 Nm yezihlanganisi ezinemisonto ye-M12 — elinganisela ukusebenza kokugcinwa koomatshini ngokuchasene nomngcipheko wokonakalisa i-interface yokutywina. Uku-torque engaphelelanga kudala isitywina esingazinzanga ngokomatshini kwaye esinokukhululeka ngenxa yokungcangcazela. Uku-torque engaphelelanga kunokucinezela kwaye konakalise i-O-ring okanye i-gasket yokutywina, oko konakalise ukusebenza kokutywina ngokusisigxina. Ngokwenyani, ndicebisa ukusebenzisa i-torque wrench okanye i-torque-limiting driver ebekwe kwixabiso le-torque elichaziweyo lomenzi, endaweni yokuxhomekeka kwi-"hand tight kunye ne-quarter turn."

Impazamo yesibini eqhelekileyo kubunzulu obungafanelekanga bokufakelwa kwephaneli. Xa isixhumi se-M12 sifakwe kwiphaneli eludongeni olubiyelweyo, ubukhulu bodonga olubiyelweyo buchaphazela ubunzulu bokufakelwa kwentambo yesixhumi. Ukuba iphaneli incinci kakhulu, ukufakelwa kwentambo kusenokunganeli ukumelana namandla okutsalwa alinganisiweyo. Ukuba iphaneli ityebile kakhulu, umzimba wesixhumi ungaphuma ezantsi ngaphambi kokuba ubuso bokuvala buqhagamshelane ngokupheleleyo nomphezulu wokuvala. Uninzi lwabavelisi luchaza uluhlu oluncinci noluphezulu lobukhulu bephaneli kwiireceptacle zabo zokufaka iiphaneli - ngokuqhelekileyo ukusuka kwi-1.5mm ukuya kwi-4mm kwiinguqulelo eziqhelekileyo. Ukusebenzisa ubukhulu bephaneli ngaphandle kolu luhlu ngaphandle kokubonisana nomenzi kunokubangela ukungaphumeleli kwesitywini okungabonakaliyo ngexesha lokufakwa kwaye kubonakale kuphela emva kwemvula yokuqala.

Impazamo yesithathu kukusebenzisa uhlobo lwentambo olungalunganga. Izihlanganisi ze-M12 zenzelwe ukusetyenziswa ngobubanzi bentambo kunye neentlobo zokwakha ezithile. Ukusebenzisa intambo enobubanzi obungaphandle obuncinci kunobubanzi bentambo yesihlanganisi kuya kubangela ukuba i-clamp ekhululekileyo inganiki ukuvalwa okanye ukukhululeka koxinzelelo olufanelekileyo. Ukusebenzisa intambo enkulu kakhulu akuyi kufaneleka okanye kuya kufuna amandla amaninzi anokonakalisa umzimba wesihlanganisi okanye ijakethi yentambo ngexesha lokuhlanganiswa. Soloko uqinisekisa uluhlu lobubanzi bentambo oluchazwe ngumvelisi wesihlanganisi kwaye uqinisekise ukuba ukwakhiwa kwentambo yakho yasentsimini (umtya omnye vs. oxineneyo, ijakethi ye-PVC vs. PUR, ekhuselweyo vs. engagqunywanga) iyahambelana noyilo lwesihlanganisi.

IiProtokholi zoLondolozo ezandisa ubomi benkonzo yoQhagamshelo

Kwiindawo zokufaka izixhobo zokulawula ngaphandle, ndicebisa ukuba kusekwe inkqubo yokukhusela equka ukuhlolwa rhoqo kwazo zonke izihlanganisi ze-M12. Ukuphindaphinda kuxhomekeke kubunzima bendawo yokufakela, kodwa kwiindawo ezininzi zokufaka izixhobo ngaphandle kwiindawo ezinemozulu eshushu okanye enemozulu yemvula, uhlolo lonyaka ngexesha lemvula lufanelekile.

Uluhlu lokuhlola kufuneka luquke ukujonga ngokubonakalayo indlu yesixhumi ukuze kubonwe iimpawu zokuwohloka kwe-UV (ukuqhekeka, ukutshixa, ukutshintsha kombala), ukuqinisekisa ukuba indlela yokutshixa izikrufu isekwixabiso le-torque elichaziweyo (kusetyenziswa isikrufu se-torque, kungekhona ngokuziva), ukuhlola indawo yokungena kwentambo ukuze kubonwe iimpawu zokuwohloka kwejakethi okanye ukungena komswakama ecaleni kwentambo, kunye nokuqinisekisa ukuba ubuso bokuvala izixhumi zephaneli zicocekile kwaye azinazo inkunkuma, i-sealant endala, okanye iimveliso zokubola ezinokuthi zonakalise ujongano lwesitywina.

Icebiso elinye elisebenzayo lokulungisa: faka i-bead encinci ye-silicone dielectric grease ebusweni bokuvala bee-M12 connectors ngaphambi kokuba ihlanganiswe. Oku kufeza iinjongo ezimbini. Okokuqala, kubonelela ngomqobo owongezelelweyo nxamnye nokungena komswakama kwindawo yokutywina. Okwesibini, isebenza njengesithambisi ngexesha lokuhlanganiswa, okwenza kube lula ukufikelela kwi-torque echanekileyo ngaphandle kokufaka uxinzelelo olongezelelweyo kwizinto zokuvala. Sebenzisa i-dielectric grease eyenzelwe ngokukodwa izihlanganisi zombane - i-grease yemoto eqhelekileyo inokuhlasela ezinye izinto zendlu kwaye inokonakalisa izinto zokuvala zerabha ngokuhamba kwexesha.
