Pogwira ntchito ndi magetsi, makamaka m'madera omwe madzi kapena chinyezi chilipo, kusankha zolumikizira zingwe zoyenera ndikofunikira. Chinthu chimodzi chofunikira pakusankha zolumikizira ndikumvetsetsa ma IP awo (Ingress Protection). Izi zikuwonetsa momwe cholumikizira chimatetezedwa ku fumbi, madzi, ndi zinthu zina zakunja. M'nkhaniyi, tiwona zomwe ma IP amatanthauza komanso momwe tingasankhire zoyeneracholumikizira chosalowa madzikwa makina anu otsika magetsi.
Kumvetsetsa ma IP mavoti
Miyezo ya IP imatanthauzidwa ndi International Electrotechnical Commission (IEC) ndipo imakhala ndi manambala awiri. Nambala yoyamba imayimira chitetezo ku zinthu zolimba (monga fumbi), pomwe nambala yachiwiri ikuwonetsa chitetezo ku zakumwa (monga madzi). Mwachitsanzo, muyezo wa IP68 umatanthauza kuti cholumikizira ndichotetezedwa mokwanira kuti fumbi lilowe ndipo chitha kupirira kumizidwa kwanthawi yayitali m'madzi.
Ma IP wamba a Zolumikizira Chingwe
• IP65: Muyezo uwu ukuwonetsa chitetezo ku fumbi lolowera ndi jeti lamadzi. Zolumikizira zokhala ndi votejizi ndizoyenera kugwiritsidwa ntchito panja pomwe zimatha kukumana ndi mvula kapena madzi otayira.
• IP67: Zolumikizira izi zimatetezedwa ku fumbi ndipo zimatha kupirira kumizidwa kwakanthawi m'madzi (mpaka mita imodzi kwa mphindi 30). Iwo ndi abwino kwa ntchito kumene madzi ingress ndi nkhawa.
• IP68: Ichi ndiye chiyerekezo chapamwamba kwambiri cha zolumikizira zopanda madzi, zomwe zikuwonetsa kutetezedwa ku fumbi komanso kumizidwa mosalekeza m'madzi. Zolumikizira zokhala ndi IP68 ndizoyenera kugwiritsa ntchito pansi pamadzi kapena malo okhala ndi madzi okwanira.
Kusankha Cholumikizira Choyenera Chopanda Madzi
Posankha cholumikizira chingwe chosalowerera madzi pamakina otsika mphamvu, ganizirani izi:
• Mikhalidwe Yachilengedwe: Yang'anani malo omwe cholumikizira chidzagwiritsidwa ntchito. Ngati cholumikizira chikhala ndi madzi, sankhani ma IP apamwamba ngati IP67 kapena IP68.
• Voltage ndi Current: Onetsetsani kuti cholumikizira chavotera mphamvu yamagetsi ndi zomwe mukufuna pakugwiritsa ntchito. Kwa makina otsika mphamvu, zolumikizira zokhala ndi voliyumu ya 450V ndi ma 15A mpaka 17.5A omwe amagwiritsidwa ntchito kwambiri.
• Kugwirizana kwa Chingwe: Sankhani zolumikizira zomwe zimagwirizana ndi kukula kwa chingwe chomwe mukugwiritsa ntchito. Mwachitsanzo, zolumikizira zimatha kukhala ndi zingwe zolimba kapena zosinthika kuyambira 0.5 mm² mpaka 2.5 mm².
• Mtundu Woyikira: Sankhani pakati pa zolumikizira zam'mbali zolumikizira chingwe cholunjika ku chingwe kapena zolumikizira zolumikizira kuti muyike pamapanelo a zida.
Zitsanzo Zothandiza
Kwa makina otsika mphamvu m'malo akunja, cholumikizira chokhala ndi IP67 chingakhale chokwanira. Zolumikizirazi zimatha kuthana ndi madzi kwakanthawi kochepa ndipo sizikhala ndi fumbi. Komabe, ngati pulogalamu yanu ikukhudzana ndi madzi mosalekeza, monga kuyika pansi pamadzi, cholumikizira chovotera IP68 ndichofunika.
Kusamalira ndi Kuyendera
Kuti muwonetsetse kutalika ndi kudalirika kwa zolumikizira zingwe zopanda madzi, kukonza nthawi zonse ndikuwunika ndikofunikira. Yang'anani zizindikiro zilizonse zowonongeka, zowonongeka, kapena zowonongeka. Bwezerani zisindikizo zilizonse zowonongeka kapena zolumikizira mwachangu kuti musunge ma IP ndikupewa zovuta zamagetsi.
Mapeto
Kumvetsetsa ma IP ndikofunika kwambiri posankha zolumikizira zingwe zopanda madzi pamakina amagetsi otsika. Posankha zolumikizira zomwe zili ndi IP yoyenera, mutha kuwonetsetsa kuti magetsi anu amakhala otetezedwa ku fumbi ndi kulowa kwa madzi. Ganizirani momwe chilengedwe chimakhalira, ma voliyumu ndi zomwe zikuchitika pano, kugwirizana kwa chingwe, ndi mtundu wa kukhazikitsa posankha zolumikizira zanu. Ndi chisankho choyenera, mutha kuwonjezera kudalirika ndi chitetezo cha makhazikitsidwe anu amagetsi.
Kuti mudziwe zambiri komanso malangizo a akatswiri, pitani patsamba lathu lahttps://www.jdtelectron.com/kuti mudziwe zambiri zazinthu zathu ndi mayankho.
