Ukuqinisekisa ubuqotho nokuphepha kokufakwa kukagesi, kubalulekile ukukhetha indlala yekhebula efanele. Izindlala zekhebula ziyizinto ezivala futhi zinqamule izintambo ezivikela ezicini zemvelo ezinjengomswakama, uthuli kanye nokucindezeleka kwemishini. Kodwa-ke, ngezinhlobonhlobo zezinto ze-cable gland ezitholakalayo emakethe, ukukhetha impahla ye-cable gland efanele endaweni yakho yohlelo lokusebenza kungaba umsebenzi onzima. Lesi sihloko sizokuqondisa ezintweni ezibalulekile zokukusiza wenze isinqumo unolwazi.
1. Qonda indawo yohlelo lokusebenza
Isinyathelo sokuqala ekukhetheni i-cable gland material efanele ukuqonda kahle indawo ezosetshenziswa kuyo. Izinto ezinjengamazinga okushisa, umswakama, ukuchayeka kumakhemikhali, nemisebe ye-UV zidinga ukucatshangelwa. Isibonelo, uma indlala yekhebula isetshenziswa endaweni yasolwandle, idinga ukumelana namanzi anosawoti kanye nokugqwala. Ngokuphambene, endaweni yezimboni ezisezingeni eliphezulu, impahla kumele ikwazi ukumelana nokushisa okukhulu ngaphandle kokuwohloka.
2. Izinto ezijwayelekile zokuxhuma ikhebula
Izindlala zekhebulangokuvamile zenziwa ngezinto ezihlukahlukene, ngayinye inezici zayo:
Ipulasitiki (i-polyamide, i-PVC): Izindlala zekhebula lepulasitiki azisindi, azikwazi ukugqwala, futhi ziyonga. Zifanele izicelo zasendlini kanye nezindawo ezinokucindezeleka okuphansi kwemishini. Kodwa-ke, zingase zingasebenzi kahle emazingeni okushisa aphakeme noma ezindaweni ezinokhahlo zamakhemikhali.
Insimbi (I-Aluminum, Insimbi Engagqwali, Ithusi): Izindlala zekhebula lensimbi zinikeza amandla amahle kakhulu nokuqina, okuzenza zilungele ukusetshenziswa komsebenzi osindayo. Insimbi engagqwali ikakhulukazi imelana nokugqwala futhi ifanele indawo yasolwandle namakhemikhali. I-Aluminium ayisindi futhi inokumelana nokugqwala okuhle, kuyilapho ithusi linamandla amangalisayo okusebenza kodwa lingadinga ukuvikeleka okwengeziwe kokugqwala.
Izinto ezikhethekile (inayiloni, i-Delrin, njll.): Izinhlelo zokusebenza ezithile zingadinga izinto ezikhethekile. Isibonelo, izindlala zezintambo zenayiloni zinamakhemikhali amahle kakhulu kanye nokumelana ne-UV, okuzenza zilungele ukusetshenziswa kwangaphandle.
3. Cabangela izilinganiso zemvelo
Lapho ukhetha indlala yekhebula, kufanele ucabangele izilinganiso zayo zemvelo, njengesilinganiso se-IP (Ingress Protection) kanye nesilinganiso se-NEMA (National Electrical Manufacturers Association). Lezi zilinganiso zibonisa izinga lokuvikela indlala yekhebula elinikezayo othulini namanzi. Isibonelo, isilinganiso se-IP68 sisho ukuthi indlala yekhebula ayiqinile uthuli futhi ingamelana nokucwiliswa okuqhubekayo emanzini, okuyenza ifaneleke ukufakwa ngaphansi kwamanzi.
4. Linganisa izidingo zemishini
Ngaphezu kwezici zemvelo, izidingo zemishini zohlelo lokusebenza nazo zidinga ukucatshangelwa. Lokhu kuhlanganisa ububanzi bekhebula, uhlobo lwekhebula elisetshenziswayo, namandla okuba nokucindezeleka komshini. Qiniseka ukuthi indlala yekhebula ekhethiwe ingakwazi ukuthwala usayizi wekhebula futhi inikeze ukukhululeka okwanele ukuvimbela ukulimala kwekhebula.
5. Ukuhambisana nezindinganiso
Okokugcina, qiniseka ukuthi izindlala zekhebula zithobela izindinganiso nemithetho yemboni efanele. Lokhu kungase kuhlanganise izitifiketi ezifana ne-UL (Underwriters Laboratories), CE (CE Mark Europe), noma i-ATEX (Isitifiketi Se-Explosive Atmospheres). Ukuthobelana nalawa mazinga kuqinisekisa ukuthi izindlala zekhebula ziyahlangabezana nezidingo zokuphepha nokusebenza kohlelo lwakho lokusebenza oluthile.
Ekuphetheni
Ukukhetha okulungileindlala yekhebulaimpahla yohlelo lwakho lokusebenza ibalulekile futhi ithinta ukuphepha nokuthembeka kokufaka kwakho ugesi. Ngokuqonda uhlelo lwakho lokusebenza, ucabangela izakhiwo zezinto ezihlukahlukene, ukuhlola izidingo zemvelo nezomshini, nokuqinisekisa ukuthobelana nezindinganiso zomkhakha, ungakhetha ngempumelelo indlala yekhebula ehlangabezana nezidingo zakho. Ukuthatha isikhathi sokwenza ukukhetha okunolwazi ekugcineni kuzothuthukisa ukusebenza nokuphila kwesistimu yakho kagesi.
