TL;DR: Isixhumi esijikelezayo esingangeni manzi se-IP55 sivimba uthuli kunye neejethi zamanzi ezinoxinzelelo oluphantsi, nto leyo eyenza ukuba ibe yeyona nqanaba liphantsi elisebenzayo kwiindawo zombane zangaphandle eziveziweyo. Izixhumi zentambo ze-M12 (IEC 61076-2-101) zezona zikhethwayo zibalaseleyo kwiindawo zokunxibelelana ngaphandle kwesiginali kunye namandla kuba umsonto wazo wokudibanisa we-12 mm, odibene nesitywina se-O-ring, unika uxinzelelo oluhambelanayo lokudibana. Uninzi lwezinto ezifakelweyo zangaphandle azidingi i-IP67. I-IP55 ingabizi kakhulu, kulula ukuyigcina, kwaye yanele imvula, uthuli, kunye nokuhlamba ngamanye amaxesha. Ifomathi ye-M12 inikezela ngeenguqulelo zekhowudi (A, B, D, X) ezithintela ukungalingani. Ukuba indawo yakho ebiyelweyo ijongene neemeko zemvula ezithe ngqo okanye umngcipheko wokuntywila, nyuka uye kwi-IP65 okanye kwi-IP67. Ngaphandle koko, isixhumi se-IP55 M12 esakhiwe kakuhle esinezindlu ezifakwe i-nickel kunye ne-silicone O-ring siya kuhlala iminyaka emihlanu ukuya kwesibhozo ngaphandle.

Isixhumi esijikelezayo esingangeni manzi esine-IP55 asisosixhumi esomeleleyo kwimarike. Asinakuntywiliselwa emanzini. Asiyi kusinda kwi-washer yoxinzelelo xa sikufutshane. Kodwa sesona silinganiso siqhelekileyo esichazwe kwiindawo zombane zangaphandle, iibhokisi ze-junction, ii-LED drivers, kunye neekhabhathi ze-telemetry kwihlabathi liphela. Ngoba? Kuba uninzi lwee-elektroniki zangaphandle azize zintywiliswe ngamanzi. Ziyana, zicocwe, kwaye ngamanye amaxesha zifakwe ngepayipi ngabasebenzi bokulungisa. I-IP55 iphatha kanye loo nto.

Igama elithi "IP" kwi-IP55 limele uKhuseleko lokungena, elibhalwe phantsi I-IEC 60529. Inombolo yokuqala, u-5, ithetha ukuba indawo evalekileyo ikhuselwe luthuli — ukungena okulinganiselweyo kuvumelekile, kodwa akwanelanga ukuphazamisana nokusebenza. Inombolo yesibini, u-5, ithetha ukuba iyakwazi ukumelana neejethi zamanzi ezinoxinzelelo oluphantsi ezivela kwi-nozzle ye-6.3 mm kwi-12.5 litres ngomzuzu imizuzu emithathu. Oko akusiyo i-splash. Loo nto yi-jet eqondisiweyo. Ukuba indawo yakho evalekileyo ihlala phantsi kwe-eave, i-canopy, okanye ivezwe nje kwimvula eqhutywa ngumoya, i-IP55 yeyona ndawo isetyenziswa kakhulu ngabasebenza ngombane kunye nabachazi.

Izihlanganisi zemisonto ye-M12 ziphambili kolu didi kuba zincinci, zisemgangathweni, kwaye zithembekile ngoomatshini. Umsonto wokudibanisa we-12 mm, ochazwe kwi I-IEC 61076-2-101, yasungulwa nguLumberg ngo-1985 yaza kamva yamkelwa yi-IEC ngo-2003. Yaba yindlela emiselweyo yokujonga iisensa zemizi-mveliso, ii-actuators, kunye ne-I/O esasazwayo. Xa ubona ikhabhinethi yokulawula yangaphandle enesixhobo esincinci esijikelezayo sigqobhoza kwiphaneli esecaleni, amathuba okuba yi-M12. Umsonto ngokwawo awusiwo umtywino. Umtywino yi-O-ring ecinezelweyo phakathi kweplagi kunye ne-receptacle njengoko umsonto uqina. Xa yenziwe ngokuchanekileyo, loo mxinano udala umqobo we-IP55 — odla ngokuba yi-IP65 okanye i-IP67 —.

Kodwa ibali lokwenyani alilo eliqhelekileyo. Ibali lokwenyani lelo liyenzeka xa uphosisa.

Ingozi Yokwenene Ekungekho Mntu Uthetha Ngayo

Uninzi lokusilela kwezixhumi zangaphandle akubi kakhulu. Ziyacotha. Amanzi angena kwi-O-ring eyonakeleyo kwiinyanga ezintandathu. Ukufuma kwakha ngaphakathi kweqokobhe lesixhumi. Izixhumi ziyanyibilika. Ukumelana kuyanyuka. Ekugqibeleni isignali iyawa, okanye i-breaker iyawa, kwaye iqela lokulungisa liqhuba iiyure ezimbini ukuya kwikhabhinethi ekude ukuze lifumanise ukuba isixhumi se-$4 sitshabalalise isilawuli se-$2,000.

Ndiyibonile le ndlela iphindaphinda kumashishini onke. Ifama yelanga eNevada isebenzisa izihlanganisi ze-IP55 kwiibhokisi zayo zokudibanisa. Uthuli lwasentlango lulungile ngokwaneleyo ukuba ludlule kwiindawo ezivalwe kakubi. Kwiminyaka emibini, ukumelana noqhagamshelwano kwizihlanganisi zamandla ze-M12 kunyuka ngokwaneleyo ukuvelisa ubushushu. Ubushushu bukhawulezisa ukuwohloka kwe-O-ring. Umjikelo uzondla ngokwawo. Kwindawo efakelweyo elunxwemeni eFlorida, ityuwa yi-salt mist yenza into efanayo ngokukhawuleza. Isihlanganisi yayiyi-IP55, kodwa izinto zokuhlala zaziyi-zinc alloy eqhelekileyo ngaphandle kwe-nickel plating. Ukubola kudla umsonto. Umfakeli akasakwazi ukuqinisa isihlanganisi kwi-torque echaziweyo. Isitywino siyasilela.

Ezi mpazamo azibangelwa kukuba i-IP55 "ibuthathaka kakhulu." Zibangelwa kukuba i-IP55 isetyenziswe kwizinto ezingalunganga, ukufakwa okungalunganga, okanye ishedyuli yokulungisa engalunganga. Umgangatho uchaza iimeko zovavanyo. Awuqinisekisi ukusebenza kwentsimi. Ngumsebenzi wakho lowo.

Ingxaki yindleko, hayi iinkcukacha. Umphathi weprojekthi uthenga izihlanganisi ze-IP55 kuba zisiqingatha sexabiso leeyunithi ze-IP67. Iphepha lokuthenga libonakala licocekile. Emva kweminyaka emithathu, amabango ewaranti aqala. Ixabiso lilonke lobunini liyatshintsha kancinci. Oko kwakubonakala ngathi ukonga kwaba yingxaki. Imbono yam: ukuba ufaka ngaphandle kwaye awukwazi ukuchukumisa izihlanganisi iminyaka emithathu, musa ukuthenga iyunithi ye-IP55 engabizi kakhulu. Thenga leyo ine-O-ring material engcono kunye ne-nickel plating etyebileyo. Awusoze uzisole.

Oko Kuthethwa Yi-IP55 Ngokwenene

I-IP55 sisithembiso esithile, asilobango elingacacanga lokuba "ukumelana namanzi." Ngokutsho kwe-IEC 60529, uvavanyo lothuli (inombolo yokuqala 5) lusebenzisa igumbi le-talc elinomgubo okhupha i-vacuum. Isixhumi sivavanywa ukuya kuthi ga kwiiyure ezisibhozo. Ukungena kothuli okulinganiselweyo kuvumelekile, kodwa akufuneki kuphazamise ukusebenza okanye ukhuseleko. Uvavanyo lwamanzi (inombolo yesibini 5) lutshiza amanzi kwi-nozzle ye-6.3 mm kwi-12.5 litres ngomzuzu ukusuka nakweyiphi na indlela kangangemizuzu emithathu. Umgama wovavanyo umalunga neemitha ezi-3. Isixhumi akufuneki sivumele amanzi ngobuninzi obuphazamisa ukusebenza.

Nantsi inkcukacha ebalulekileyo: uvavanyo lwe-IP55 luthatha ukuba isixhumi sikwindawo yaso yokusebenza eqhelekileyo. Ukuba indawo yakho ebiyelweyo ibekwe phezulu, okanye ukuba isixhumi sijonge phezulu, amanzi anokuhlangana ngeendlela ebezingalindelwanga ngumgangatho. Umxhuzulane awuyonxalenye yenkqubo yovavanyo. Ndibone izixhumi ze-M12 zifakelwe i-receptacle ijonge phezulu, iqokelela amanzi kwindawo enomsonto. Kwaneeyunithi ze-IP67 ziya kuba nzima ngaloo nto.

Ngoku thelekisa i-IP55 nabamelwane bayo. I-IP54 ikhusela emanzini atshizayo, hayi iijethi. I-IP65 ayivali uthuli kwaye ikhuselwe yijethi. I-IP67 yongeza ukuntywiliselwa okwethutyana. Umsantsa ophakathi kwe-IP55 kunye ne-IP65 mncinci kunomsantsa ophakathi kwe-IP55 kunye ne-IP54. I-IP55 luvavanyo lokuqala apho amanzi anyanzelwa khona kwindawo ebiyelweyo, engavumelekanga nje ukuba iwele kuyo. Kwiindawo ezibiyelweyo zangaphandle phantsi kweengca okanye kwimozulu ephakathi, i-IP55 idla ngokuba yindawo entle. Kwiindawo ezinxweme, ezishushu, okanye ezinoxinzelelo oluphezulu, i-IP65 ngumgangatho okhuselekileyo.

I-equivalent yaseMntla Melika yi-NEMA 3 okanye i-3R, ehambelana ne-IP55 phantsi kwe- NO 250 umgangatho. Nangona kunjalo, ukulinganiswa kwe-NEMA kuquka uvavanyo olongezelelweyo lokwakheka komkhenkce, ukugqwala, kunye nokuqhekeka kwe-conduit yangaphandle okungagutyungelwa yi-IEC 60529. Ezi nkqubo zimbini azitshintshi. Ukuba uthengisa eMntla Melika, udinga uluhlu lwe-NEMA. Ukuba uthengisa eYurophu, i-IEC 60529 ngumthetho. Abavelisi abaninzi behlabathi ngoku baqinisekisa zombini ezi zinto ukuze baphephe ukungqubana kwemarike.

Ingxoxo ye-M12: Kutheni Yaba Yinto Engagqibekanga

Isixhumi se-M12 asiso sodwa ifomathi ejikelezayo engangeni manzi. I-M8 incinci kodwa inqunyelwe kumbane ophantsi. I-M16 kunye ne-M23 ziphethe amandla amaninzi kodwa zifuna indawo engaphezulu kwephaneli kwaye zibiza ngaphezulu. I-M12, enobubanzi bentambo ye-12 mm, iphakathi. Ithwala umbane owaneleyo wezixhobo zokuvavanya kunye nee-actuator ezincinci (ukuya kuthi ga kwi-16A kwiindidi zamandla). Incinci ngokwaneleyo ukuba ingene kumngxunya wephaneli ye-16 mm. Ixabiso liphantsi ngokwaneleyo ukuba ungayitshintsha ngaphandle kwengxoxo malunga ne-oda yokuthenga.

Eyona ngqondo ye-M12 yinkqubo yokubhala ikhowudi. Izihlanganisi ezinekhowudi ye-A ziphethe iisensa kunye namandla e-DC. Ikhowudi ye-B yenzelwe iProfibus. Ikhowudi ye-D iphatha i-Ethernet ye-100 Mbps. Ikhowudi ye-X ityhala ukuya kwi-10 Gbps. Iikhowudi ze-K, L, S, kunye ne-T ziphatha amandla e-AC ukuya kuthi ga kwi-630V. Olu phawu lokufaka isitshixo luthintela ukungasebenzi kakuhle. Awunakufaka ngempazamo intambo ye-Ethernet kwi-receptacle yamandla ye-230V. Kwiifektri zangaphandle, apho iingcali zisebenza ebusuku, xa imvula ina, kwaye phantsi koxinzelelo lwexesha, oku akuyonto ilula. Luphawu lokhuseleko.

Indlela esebenza ngayo intambo ngokwayo ilula. Iplagi yesilisa inomsonto wangaphandle we-M12 x 1.0. Isitya sebhinqa sine-coupling nut yokudibana. Njengoko i-nut iqina, ubuso bangaphambili beplagi bucinezela i-O-ring ehleli kwi-receptacle groove. Umsonto ubonelela ngokugcinwa koomatshini kunye nokumelana nokungcangcazela. I-O-ring ibonelela ngesitywino. Umgangatho wesitywino uxhomekeke kwizinto ezintathu: izinto ze-O-ring, ipesenti yokucinezelwa, kunye nokugqitywa komphezulu.

Iiringi ze-silicone O zezona zisetyenziswa ngaphandle. Ziyakwazi ukumelana ne--40°C ukuya kwi-+200°C, ziyamelana ne-UV, kwaye zihlala ziguquguquka. I-Fluoroelastomer (FKM/Viton) iyafuneka ukuze ifuthwe, iioyile, okanye amaqondo obushushu aphezulu ahlala ixesha elide. I-EPDM iphatha umphunga kodwa ayilungelanga xa ithelekiswa nepetroli. I-NBR ixabisa kancinci kodwa yonakala xa ikhanyiswe lilanga. Kwiindawo zombane zangaphandle, i-silicone yeyona ndlela ikhuselekileyo. Kwiindawo zolwandle okanye zaselwandle, i-FKM yeyona ndlela ikhuselekileyo.

Izinto zendlu zibalulekile. I-brass nickel-plated inika ukuxhathisa ukugqwala okungcono kunye nokuqina kwemisonto. I-alloy ye-zinc ene-nickel plating ixabisa kancinci kwaye iyamkeleka kwiindawo ezininzi zoshishino. I-PA66 egcwele iglasi yindlela engabizi kakhulu kwizicelo ezingabalulekanga. Ilula kwaye inokubunjwa kodwa inokuqhekeka phantsi kwe-torque engaphezulu. Intsimbi engatyiwayo 316 ngumgangatho wegolide wolwandle. Ixabisa ngokuphindwe kathathu ukuya kahlanu kune-brass nickel-plated.

Izihlanganisi zihlala zi-phosphor bronze kunye ne-gold plating phezu kwe-nickel. Ubukhulu begolide buqala kwi-0.1 ukuya kwi-1.0 microns. I-thicker plating isinda kwimijikelo emininzi yokudibana. I-M12 connector eqhelekileyo ilinganiswa kwimijikelo yokudibana eyi-100 ukuya kwi-500. Iindidi eziphezulu zifikelela kwi-5,000 nangaphezulu. Kwiifektri zangaphandle ezizinzileyo ezichukunyiswa kanye ngonyaka ngexesha lokulungiswa, imijikelo eyi-100 yanele. Kwizixhobo zovavanyo okanye oomatshini abaphathwayo, i-500 yeyona incinci.

Xa i-IP55 Yanele, kwaye Xa Inganelanga

I-IP55 yanele xa indawo ebiyelweyo imile nkqo, imvula yeyona mithombo yamanzi iphambili, kwaye uthuli luyinto eqhelekileyo yasezidolophini okanye kwimizi-mveliso. Izibane zasezitalatweni, iikhabhathi zokulawula izithuthi, iiyunithi zetelemetry ezikude, kunye neebhokisi ze-solar combiner zonke ziwela kolu didi. Isixhumi asikho phantsi kwamanzi. Asicocwa ngomphunga. Siyana kwaye ngamanye amaxesha siyasulwa.

I-IP55 ayanelanga xa indawo ebiyelweyo ikufutshane nomhlaba kwiindawo ezithandwa zizikhukula, xa ukuhlamba ngoxinzelelo oluphezulu kuyinto eqhelekileyo (ukulungiswa kokutya, ezolimo), okanye xa isixhumi singafakwanga kwindawo emanzi. Njengoko iingcali zekhonkco ziphawula, ireyithingi ye-IP yenkqubo yesixhumi idla ngokubhekisa kwimeko yokudibana. Nje ukuba ikhutshwe kwiplagi, i-receptacle yehla iye kwi-IP55 okanye ezantsi ngaphandle kokuba kufakwe isiciko sothuli esivaliweyo. Yingakho izixhumi zokutshaja ze-EV kufuneka zigcine i-IP55 nokuba isiphatho sisusiwe kwisithuthi. Uvavanyo lunzima, kwaye ixabiso liyabonakalisa oko.

Ingcebiso yam ngokuthenga: qala nge-IP55 kwimeko engama-80%. Sebenzisa i-IP65 kwiindawo zasentlango ezikunxweme, ezishushu, okanye ezinothuli oluninzi. Sebenzisa i-IP67 kuphela xa ukuntywiliselwa okwethutyana kuyingozi yokwenyani - amagumbi angaphantsi komhlaba, imingxunya, iidekhi zaselwandle. I-IP68 yeyokuntywiliselwa okuqhubekayo kwaye igqithisile kwi-95% yeendawo zombane zangaphandle. Inyathelo ngalinye liphinda kabini ixabiso lesixhumi. Ixabiso lokuntywiliselwa likwanyuka kuba izinto zegasket, indlela yokutshixa, kunye nokunyamezela kokwenziwa kwemveliso kuyaqina.

Kukho umgibe wokuthenga endiwubona ngokuphindaphindiweyo: ukuthenga izihlanganisi ze-IP67 nokuzifakela kwindawo evalekileyo ye-IP55. Ikhonkco elibuthathaka yindawo evalekileyo. Amanzi angena nge-gasket yomnyango, aqubhe ezantsi, aze antywilisele indawo evalekileyo. Ikhonkco le-IP67 liyasinda. Indawo evalekileyo ayiphumeleli. Inkqubo iyasilela. Tshatisa isihlanganisi nendawo evalekileyo. Tshatisa indawo evalekileyo nendawo engqongileyo. Musa ukuqwalasela kakhulu inxalenye enye uze uqwalasele ezinye.

Ityala elivela ebaleni

Ngowama-2023, iprojekthi yokukhanyisa i-LED yemizi-mveliso eTexas isebenzise izihlanganisi ze-IP55 M12 kwiikhabhathi zolawulo zangaphandle ezingama-300. Ingcaciso yayicacile: IP55, ikhowudi ye-A, iiphini ezi-4, indlu ye-nickel egqunywe yibrass, i-silicone O-ring. Umthengisi unikezele nge-spec. Ufakelo belucocekile. Kwiinyanga ezisibhozo, iingxelo zokungaphumeleli zaqala ukufika zivela kumda osentshona wesiza.

Uphando lutyhile unobangela olulula: iikhabhinethi zasentshona zijongene nomoya okhoyo, owawuthwele uthuli lwe-caliche olucolekileyo oluvela kwindawo yokwakha ekufutshane. Uvavanyo lothuli lwe-IP55 lusebenzisa i-talc. Uthuli lwe-Caliche lubukhali, lurhabaxa ngakumbi, kwaye lune-calcium carbonate. Uthuli lungene kwindawo yokudibanisa ngobuninzi obungalindelwanga ngumgangatho. Aluzange lubangele ukusilela kwangoko. Endaweni yoko, lwaqokelelana lujikeleze umngxuma we-O-ring, lwenza intlama yokusila. Ngalo lonke ixesha ulungiso luqhawula intambo yokuvavanya, uthuli lwalufaka umphezulu we-O-ring. Emva kokuqhawulwa kathandathu, isitywina sasichaphazeleka. Amanzi angena ngexesha lesiganeko semvula esilandelayo. Izikhonkwane zatsha. Izibane zacima.

Ulungiso belungeyiyo ukuhlaziya ukuya kwi-IP67. Bekukukutshintshela kwizihlanganisi eziqinileyo zothuli ze-IP65 ezine-O-ring compression ratio eqinileyo kancinci kwaye kongezwe isigqubuthelo sothuli kuyo nayiphi na i-receptacle engaguqukiyo. Ukunyuka kweendleko bekuyi-$0.40 kwisihlanganisi ngasinye. Izinga lokusilela lehle laya kwi-zero. Isifundo: I-IP55 iphatha uvavanyo. Ayiphathi yonke imeko yentsimi. Ulwazi lwengingqi lubaluleke ngaphezu kwephepha leenkcazo.

Ukuthenga Ngaphandle Kokuzisola

Xa ufuna izihlanganisi ezijikelezayo ezingangeni manzi kwiindawo zokugquma zangaphandle, buza umthengisi imibuzo emihlanu. Okokuqala: ithini ireyithingi ye-IP echanekileyo, kwaye ngaba iqinisekisiwe yilebhu yomntu wesithathu okanye iyazibhengeza? Okwesibini: ithini impahla ye-O-ring, kwaye ingakanani iqondo lobushushu? Okwesithathu: ingakanani ireyithingi yomjikelo wokudibana, kwaye ngaba ubukhulu beplati yokunxibelelana buhlangabezana neshedyuli yakho yokugcinwa? Okwesine: ngaba izinto zokuhlala ziyahambelana nendawo ohlala kuyo — i-zinc alloy yemizi-mveliso eyomileyo, i-brass nickel yangaphandle ngokubanzi, intsimbi engatyiwayo yolwandle? Okwesihlanu: ingakanani ubungakanani bomngxuma wephaneli kunye nobude bokudityaniswa kwentambo, kwaye iyahambelana noyilo lwakho lwendawo yokugquma?

Musa ukwamkela iimpendulo ezingacacanga. "I-IP55 elinganiswe" ngaphandle kwesatifikethi sovavanyo libango nje. Umthengisi othembekileyo uya kunika ingxelo yovavanyo lwe-IEC 60529, isatifikethi sokuthobela i-RoHS, kunye nephepha ledatha elibalulekileyo. Ukuba abakwazi, qhubeka ukhangela. Ixabiso lesixhumi esingasebenziyo kwikhabhinethi ekude alikho nje ixabiso lesixhumi. Lixabiso lomsebenzi, uhambo, ixesha lokungasebenzi, kunye nesikhalazo somthengi.

Imigca yemveliso enxulumene nabakhi beepaneli ibandakanya iibhloko zesiphelo kunye neenkqubo zolawulo lweengcingo ezenza kube lula ukufakelwa kweengcingo kwindawo ebiyelweyo. Umzekelo, Ibhloko yesiphelo sendlela yokutyhala uloliwe ye-PCT-211 DIN kunciphisa ixesha lokuxhuma ngokuphelisa ukujonga i-screw torque. Uqhagamshelo lwe-spring-clamp lugcina uxinzelelo loqhagamshelwano ngokungcangcazela kunye nokujikeleza kobushushu, nto leyo ibalulekileyo kwiikhabhathi zangaphandle apho ubushushu bukhula khona imihla ngemihla. Khangela yonke into. ikhathalogu yesixhumi kunye nebhloko yesiphelo kwiindawo ezidityanisiweyo zokuvala.

Into yokugqibela kwi-torque. Umsonto we-M12 kufuneka uqiniswe ngokweemfuno zomenzi, ngesiqhelo i-0.8 ukuya kwi-1.2 Nm. I-over-torque icinezela i-O-ring ngaphaya komda wayo we-elastic. Iyaguquguquka ngokusisigxina kwaye ayiphindi ibuyele esiqhelweni. I-Under-torque ishiya izikhewu. Sebenzisa isikrufu se-torque. Musa ukuqikelela. Umahluko phakathi koqhagamshelo oluqinileyo kunye noqhagamshelo oluvaliweyo ulinganiswa, awubonakali lula.
