TL;DR: Cholumikizira chozungulira chosalowa madzi cha IP55 chimatseka fumbi ndi madzi otsika mphamvu, zomwe zimapangitsa kuti chikhale chovomerezeka kwambiri pa malo olumikizira magetsi akunja. Zolumikizira ulusi wa M12 (IEC 61076-2-101) ndizosankha zazikulu pa kulumikizana kwa chizindikiro chakunja ndi mphamvu chifukwa ulusi wawo wolumikizira wa 12 mm, wolumikizidwa ndi chisindikizo cha O-ring, umapereka mphamvu yogwirizana nthawi zonse. Malo ambiri okhazikitsa akunja safuna IP67. IP55 ndi yotsika mtengo, yosavuta kusamalira, komanso yokwanira mvula, fumbi, komanso nthawi zina kusamba. Mtundu wa M12 umapereka mitundu yosiyanasiyana ya ma code (A, B, D, X) yomwe imaletsa kusagwirizana. Ngati malo anu olumikizirana akukumana ndi nyengo yamvula kapena chiopsezo cha kumizidwa, pitani ku IP65 kapena IP67. Kupanda kutero, cholumikizira cha IP55 M12 chomangidwa bwino chokhala ndi nyumba yophimbidwa ndi nickel ndi silicone O-ring chidzakhalapo kwa zaka zisanu mpaka zisanu ndi zitatu panja.

Cholumikizira chozungulira chosalowa madzi chomwe chili ndi IP55 sichili cholumikizira cholimba kwambiri pamsika. Sichingathe kumizidwa. Sichingapulumuke ndi chotsukira cha pressure chomwe chili pafupi. Komabe ndi chizindikiro chodziwika bwino chomwe chimaperekedwa pa malo osungira magetsi akunja, mabokosi olumikizira magetsi, ma LED driver, ndi makabati a telemetry padziko lonse lapansi. Chifukwa chiyani? Chifukwa zamagetsi ambiri akunja samira. Amanyowa, kutsukidwa fumbi, komanso nthawi zina kutsukidwa ndi anthu okonza. IP55 imagwira ntchito bwino kwambiri.

"IP" mu IP55 imayimira Chitetezo cha Kulowa, yomwe yalembedwa pansi pa IEC 60529. Manambala oyamba, 5, amatanthauza kuti malo obisikawo ali ndi fumbi lotetezedwa — kulowetsedwa kochepa kumaloledwa, koma sikokwanira kusokoneza ntchito. Manambala achiwiri, 5, amatanthauza kuti amapirira majeti amadzi otsika mphamvu kuchokera ku nozzle ya 6.3 mm pa malita 12.5 pamphindi kwa mphindi zitatu. Si madzi okwanira. Umenewo ndi jeti yolunjika. Ngati malo anu obisikawo amakhala pansi pa denga, denga, kapena angokumana ndi mvula yoyendetsedwa ndi mphepo, IP55 ndiye malo oyambira amagetsi ndi zida zowunikira zomwe amafikira.

Zolumikizira ulusi wa M12 ndizofunika kwambiri m'gululi chifukwa ndi zazing'ono, zokhazikika, komanso zodalirika pamakina. Ulusi wolumikizira wa 12 mm, womwe wafotokozedwa mu IEC 61076-2-101, idapangidwa ndi Lumberg mu 1985 ndipo pambuyo pake idagwiritsidwa ntchito ndi IEC mu 2003. Idakhala njira yolumikizirana yokhazikika ya masensa amafakitale, ma actuator, ndi I/O yogawidwa. Mukawona kabati yowongolera yakunja yokhala ndi cholumikizira chaching'ono chozungulira ikulowa m'mbali mwa bolodi, mwayi ndi wakuti ndi M12. Ulusi wokha si chisindikizo. Chisindikizo ndi mphete ya O yomwe yapanikizidwa pakati pa pulagi ndi cholandirira pamene ulusiwo ukulimba. Mukachita bwino, kukanikiza kumeneko kumapanga chotchinga cha IP55 — nthawi zambiri IP65 kapena IP67 —.

Koma nkhani yeniyeni si muyezo. Nkhani yeniyeni ndi zomwe zimachitika mukalakwitsa.

Chiwopsezo Chenicheni Chimene Palibe Amene Amalankhulapo

Kulephera kwa ma connector ambiri akunja sikwachilendo. Kumachitika pang'onopang'ono. Madzi amalowa mu O-ring yomwe yawonongeka kwa miyezi isanu ndi umodzi. Kuundana kumapangika mkati mwa chipolopolo cha cholumikizira. Zolumikizirazo zimasungunuka. Kukana kumakwera. Pamapeto pake chizindikiro chimatsika, kapena chosweka chimagwa, ndipo gulu lokonza limayendetsa maola awiri kupita ku kabati yakutali kuti lipeze cholumikizira cha $4 chomwe chawononga chowongolera cha $2,000.

Ndaona izi zikubwerezabwereza m'mafakitale osiyanasiyana. Famu yamagetsi yamagetsi ku Nevada imagwiritsa ntchito zolumikizira za IP55 pamabokosi ake ophatikiza. Fumbi la m'chipululu ndi labwino mokwanira kudutsa m'malo olumikizira osatsekedwa bwino. Kwa zaka ziwiri, kukana kwa kulumikizana kwa zolumikizira zamagetsi za M12 kumakwera mokwanira kuti kupange kutentha. Kutentha kumathandizira kuwonongeka kwa O-ring. Kuzungulira kumeneku kumadzidyetsa lokha. Pakuyika kwa m'mphepete mwa nyanja ku Florida, utsi wamchere umachita chimodzimodzi mwachangu. Cholumikiziracho chinali IP55, koma zinthu zomwe zinali mkati mwake zinali zinc alloy wamba popanda nickel plating. Dzimbiri limadya ulusi. Wokhazikitsa sangathenso kulimbitsa cholumikiziracho ku torque yomwe yatchulidwa. Chisindikizocho chimalephera.

Kulephera kumeneku sikumachitika chifukwa cha IP55 kukhala "yofooka kwambiri." Kumachitika chifukwa cha IP55 kugwiritsidwa ntchito pazinthu zolakwika, kuyika kolakwika, kapena nthawi yokonza yolakwika. Muyezowu umafotokoza momwe mayeso amayendere. Sizitsimikizira kuti ntchito yamunda ikuyenda bwino. Ndi ntchito yanu imeneyo.

Vuto lalikulu ndi mtengo, osati mfundo zenizeni. Woyang'anira polojekiti amagula zolumikizira za IP55 chifukwa ndi theka la mtengo wa mayunitsi a IP67. Pepala logulira limawoneka loyera. Patatha zaka zitatu, zopempha za chitsimikizo zimayamba. Mtengo wonse wa umwini umasinthasintha pang'onopang'ono. Zomwe zimawoneka ngati ndalama zosungidwa zinakhala vuto. Maganizo anga: ngati mukuyika panja ndipo simungathe kukhudza zolumikizira kwa zaka zitatu, musagule chipangizo chotsika mtengo kwambiri cha IP55. Gulani chomwe chili ndi zinthu zabwino kwambiri za O-ring komanso nickel plating yokhuthala kwambiri. Simudzadandaula nazo.

Kodi IP55 Imatanthauza Chiyani Kwenikweni?

IP55 ndi lonjezo lenileni, osati mawu omveka bwino akuti "sagwira madzi." Malinga ndi IEC 60529, kuyesa fumbi (chiwerengero choyamba 5) kumagwiritsa ntchito chipinda cha ufa chokhala ndi vacuum chotulutsa. Cholumikizira chimayesedwa kwa maola asanu ndi atatu. Kulowa pang'ono kwa fumbi kumaloledwa, koma sikuyenera kusokoneza magwiridwe antchito kapena chitetezo. Kuyesa kwa madzi (chiwerengero chachiwiri 5) kumapopera madzi kuchokera ku nozzle ya 6.3 mm pa malita 12.5 pamphindi kuchokera mbali iliyonse kwa mphindi zitatu. Mtunda woyeserera ndi pafupifupi mamita atatu. Cholumikiziracho sichiyenera kuloleza madzi ambiri omwe amalepheretsa kugwira ntchito.

Nayi mfundo yofunika: mayeso a IP55 akuganiza kuti cholumikizira chili pamalo ake oyenera. Ngati cholumikizira chanu chayikidwa mozondoka, kapena ngati cholumikiziracho chaloza mmwamba, madzi amatha kusonkhana m'njira zomwe muyezo sunayembekezere. Mphamvu yokoka si gawo la njira yoyesera. Ndawona zolumikizira za M12 zitayikidwa ndi chotengera choyang'ana molunjika mmwamba, chikusonkhanitsa madzi m'chibowo cholumikizidwa. Ngakhale mayunitsi a IP67 adzavutika ndi zimenezo.

Tsopano yerekezerani IP55 ndi mayiko ena. IP54 imateteza madzi otuluka, osati ma jet. IP65 ndi yolimba ngati fumbi ndipo imatetezedwa ndi jet. IP67 imawonjezera kumiza kwakanthawi. Mpata pakati pa IP55 ndi IP65 ndi wocheperako kuposa mpata pakati pa IP55 ndi IP54. IP55 ndiye mlingo woyamba pomwe madzi amakakamizidwa mwamphamvu pamalo otsekedwa, osati kungololedwa kugwa pa iwo. Pa malo otsekedwa akunja pansi pa makoma kapena m'malo ocheperako, IP55 nthawi zambiri imakhala malo abwino. Pamalo otsekedwa m'mphepete mwa nyanja, otentha, kapena malo otsukira madzi okhala ndi mphamvu zambiri, IP65 ndiye pansi potetezeka.

Chofanana ndi cha ku North America ndi NEMA 3 kapena 3R, chomwe chikuwonetsa IP55 pansi pa NO 250 muyezo. Komabe, ziwerengero za NEMA zikuphatikizapo mayeso ena okhudza mapangidwe a ayezi, dzimbiri, ndi kugwedezeka kwa machubu akunja omwe IEC 60529 siikuphimba. Machitidwe awiriwa sasinthasintha. Ngati mukugulitsa ku North America, muyenera kulembetsa ku NEMA. Ngati mukugulitsa ku Europe, IEC 60529 ndiye lamulo. Opanga ambiri padziko lonse lapansi tsopano akuvomereza zonsezi kuti apewe kukangana pamsika.

Ulusi wa M12: Chifukwa Chake Unakhala Wokhazikika

Cholumikizira cha M12 sichokhacho chomwe chimakhala chozungulira chosalowa madzi. M8 ndi yaying'ono koma imangokhala ndi mphamvu yochepa. M16 ndi M23 zimagwira ntchito ndi mphamvu zambiri koma zimafuna malo ambiri a panel ndipo zimadula mtengo. M12, yokhala ndi ulusi wa 12 mm m'mimba mwake, ili pakati. Imakhala ndi mphamvu yokwanira masensa ndi ma actuator ang'onoang'ono (mpaka 16A pamagetsi osiyanasiyana). Ndi yaying'ono yokwanira kulowa m'bowo la panel la 16 mm. Ndi yotsika mtengo yokwanira kuisintha popanda mkangano wokhudza kugula.

Luso lenileni la M12 ndi makina olembera ma code. Zolumikizira za A-coded zimakhala ndi masensa ndi mphamvu ya DC. B-coded ndi ya Profibus. D-coded imagwirira 100 Mbps Ethernet. X-coded imakankhira ku 10 Gbps. Ma code a K, L, S, ndi T amagwirira mphamvu ya AC mpaka 630V. Kuyika makiyi kumeneku kumaletsa kusagwirizana. Simungathe kulumikiza chingwe cha Ethernet mwangozi mu cholandirira chamagetsi cha 230V. Mu malo oyika panja, komwe akatswiri amagwira ntchito usiku, mvula, komanso nthawi ikagwa, izi sizothandiza. Ndi chitetezo.

Kapangidwe ka ulusi ndi kowongoka. Pulagi yaimuna ili ndi ulusi wakunja wa M12 x 1.0. Chotengera chachikazi chili ndi nati yolumikizirana. Pamene natiyo ikulimba, nkhope yakutsogolo ya pulagiyo imakanikiza mphete ya O yomwe ili mumzere wolumikizira. Ulusiwo umapereka mphamvu yosunga ndi kugwedezeka. Mphete ya O imapereka chisindikizo. Ubwino wa chisindikizocho umadalira zinthu zitatu: Chida cha mphete ya O, kuchuluka kwa kupsinjika, ndi kutha kwa pamwamba.

Zingwe za silicone O-rings ndizogwiritsidwa ntchito panja nthawi zonse. Zimatha kugwira ntchito ndi -40°C mpaka +200°C, zimalimbana ndi UV, ndipo zimakhala zosinthasintha. Fluoroelastomer (FKM/Viton) imafunika kuti igwiritsidwe ntchito ndi mafuta, mafuta, kapena kutentha kwambiri. EPDM imasamalira nthunzi koma siili bwino ku mafuta. NBR ndi yotsika mtengo koma imawonongeka ndi dzuwa. Pazitseko zamagetsi zakunja, silicone ndi yabwino kwambiri. Pazitseko zamadzi kapena zakunja, FKM ndi yabwino kwambiri.

Zipangizo za nyumba ndizofunikira kwambiri. Chokutidwa ndi nickel cha mkuwa chimapereka kukana dzimbiri komanso kulimba kwa ulusi. Zinc alloy yokhala ndi nickel plating ndi yotsika mtengo komanso yovomerezeka m'malo ambiri amafakitale. PA66 yodzazidwa ndi galasi ndiyo njira yotsika mtengo yogwiritsira ntchito zinthu zosafunikira. Ndi yopepuka komanso yowumbika koma imatha kusweka chifukwa cha mphamvu ya torque. Chitsulo chosapanga dzimbiri 316 ndiye muyezo wa golide wa m'madzi. Chimawononga ndalama zokwana katatu mpaka kasanu kuposa chokutidwa ndi nickel cha mkuwa.

Zolumikizira nthawi zambiri zimakhala ndi phosphor bronze yokhala ndi golide pamwamba pa nickel. Kukhuthala kwa golide kumakhala pakati pa ma microns 0.1 mpaka 1.0. Kukhuthala kokhuthala kumapitirira nthawi zambiri zolumikizirana. Cholumikizira cha M12 chokhazikika chimayesedwa kuti chigwirizane ndi nthawi 100 mpaka 500 zolumikizirana. Mitundu yapamwamba imafika 5,000 kapena kuposerapo. Pazokhazikitsa zakunja zokhazikika zomwe zimakhudzidwa kamodzi pachaka panthawi yokonza, nthawi 100 ndizokwanira. Pazida zoyesera kapena makina onyamulika, 500 ndiye yocheperako.

Pamene IP55 Yakwanira, Ndipo Pamene Siyokwanira

IP55 ndi yokwanira ngati malo otchingira ali olunjika, mvula ndiye gwero lalikulu la madzi, ndipo fumbi ndi tinthu tambirimbiri ta m'matauni kapena m'mafakitale. Magetsi a mumsewu, makabati owongolera magalimoto, mayunitsi a telemetry akutali, ndi mabokosi ophatikiza dzuwa onse ali m'gululi. Cholumikizira sichili pansi pa madzi. Sichikutsukidwa ndi nthunzi. Chikugwetsedwa mvula ndipo nthawi zina chimapukutidwa.

IP55 sikokwanira ngati malo otchingira ali pafupi ndi nthaka m'malo omwe madzi amatha kusefukira, pamene kusamba ndi mpweya wochuluka kumachitika nthawi zonse (kukonza chakudya, ulimi), kapena pamene cholumikiziracho sichinakhazikitsidwe m'malo onyowa. Monga momwe akatswiri olumikizira amanenera, IP rating ya makina olumikizira nthawi zambiri imatanthauza momwe makinawo amagwirizanirana. Akangotsegula cholumikizira, cholandirira chimatsika kufika pa IP55 kapena kutsika pokhapokha ngati chivundikiro cha fumbi chotsekedwa chayikidwa. Ichi ndichifukwa chake zolumikizira zoyatsira magetsi ziyenera kukhala ndi IP55 ngakhale chogwiriracho chitachotsedwa mgalimoto. Kuyesako kumakhala kovuta, ndipo mtengo wake umasonyeza zimenezo.

Malangizo anga pa kugula: yambani ndi IP55 pa 80% ya malo osungiramo magetsi. Gwiritsani ntchito IP65 m'malo a m'mphepete mwa nyanja, otentha, kapena m'chipululu cha fumbi lambiri. Gwiritsani ntchito IP67 pokhapokha ngati kumiza kwakanthawi kuli pachiwopsezo chenicheni - m'zipinda zapansi, m'maenje, m'mabwalo amadzi. IP68 ndi yomiza kosalekeza ndipo ndi yochulukirapo pa 95% ya malo osungiramo magetsi akunja. Gawo lililonse lokwera limawirikiza kawiri mtengo wa cholumikizira. Mtengo wa malo osungiramo magetsi umakweranso chifukwa zinthu zosungiramo magetsi, makina otsekera, ndi zololera zopangira zimakhala zolimba.

Pali msampha wogula womwe ndimawona mobwerezabwereza: kugula zolumikizira za IP67 ndikuziyika mu chipinda cholumikizira cha IP55. Cholumikizira chofooka ndi chipinda cholumikizira. Madzi amalowa kudzera pa gasket ya chitseko, amathira pansi, ndikumiza cholumikizira. Cholumikizira cha IP67 chimapulumuka. Chipindacho sichimapulumuka. Dongosolo limalephera. Lumikizani cholumikizira ndi chipinda cholumikizira. Lumikizani chipindacho ndi chilengedwe. Musamachulukitse gawo limodzi ndikuchepetsa zina zonse.

Nkhani Yochokera Kumunda

Mu 2023, pulojekiti ya magetsi a LED ku Texas inagwiritsa ntchito zolumikizira za IP55 M12 pa makabati 300 owongolera akunja.
