Ukuqinisekisa ukuthembeka kunye nokukhuseleka kofakelo lombane, kubalulekile ukukhetha intambo yentambo efanelekileyo. Amadlala ekhebhu atywina kwaye aphelise izixhobo zeentambo ezikhusela kwizinto zokusingqongileyo ezifana nokufuma, uthuli kunye noxinzelelo lomatshini. Nangona kunjalo, ngeentlobo ezininzi zezixhobo ze-cable gland ezikhoyo kwimarike, ukukhetha i-cable gland imathiriyeli efanelekileyo kwindawo yakho yesicelo kunokuba ngumsebenzi onzima. Eli nqaku liza kukukhokela kwiingcamango eziphambili zokukunceda wenze isigqibo esinolwazi.
1. Qonda imeko yesicelo
Isinyathelo sokuqala ekukhetheni izinto ezifanelekileyo zentambo yentambo kukuqonda kakuhle indawo eza kusetyenziswa kuyo. Izinto ezinjengobushushu, ukufuma, ukuchanabeka kwimichiza, kunye nemitha yeUV kufuneka ziqwalaselwe. Ngokomzekelo, ukuba idlala lekheyibhile lisetyenziswa kwindawo ehlala elwandle, kufuneka lixhathise kumanzi anetyuwa nakumhlwa. Ngokwahlukileyo, kwindawo yoshishino oluphezulu, izinto eziphathekayo kufuneka zikwazi ukumelana nokushisa okukhulu ngaphandle kokuthotywa.
2. Izinto eziqhelekileyo zokudibanisa ikhebula
Amadlala ekhebhulazihlala zenziwe ngezinto ezahlukeneyo, nganye ineempawu zayo:
Iplastiki (i-polyamide, i-PVC): Amadlala entambo yePlastiki alula, awanyangeki ku-corrosion, kwaye ayongayo. Zifanelekile kwizicelo zangaphakathi kunye neendawo ezinoxinzelelo oluphantsi lomatshini. Nangona kunjalo, zisenokungasebenzi kakuhle kumaqondo obushushu agqithisileyo okanye kwimo engqongileyo yeekhemikhali eziqatha.
Isinyithi (iAluminiyam, iStainless Steel, iBrass): Amadlala entambo yentsimbi anika amandla agqwesileyo kunye nokuqina, okwenza ukuba alungele usetyenziso olunzima. Intsimbi estainless iyakwazi ukumelana nomhlwa kwaye ifanelekile kwimo engqongileyo yaselwandle neyekhemikhali. I-aluminiyam ikhaphukhaphu kwaye inokumelana nokuthotywa okulungileyo, ngelixa ubhedu lunamandla abalaseleyo omatshini kodwa lunokufuna ukhuseleko olongezelelweyo lokutya.
Izinto ezikhethekileyo (inayiloni, iDelrin, njl.): Ukusetyenziswa okuthe ngqo kunokufuna izinto ezikhethekileyo. Umzekelo, amadlala ekheyibhile enayiloni anemichiza egqwesileyo kunye nokuxhathisa kwe-UV, ezenza zilungele ukusetyenziswa kwangaphandle.
3. Qwalasela amanqanaba okusingqongileyo
Xa ukhetha i-cable gland, kufuneka uqikelele ukulinganiswa kwayo kokusingqongileyo, njenge-IP (Ingress Protection) yokukala kunye ne-NEMA (National Electrical Manufacturers Association) yokukala. Ezi zilinganiso zibonisa iqondo lokukhusela i-cable gland enikezela ngothuli kunye namanzi. Umzekelo, ukulinganisa kwe-IP68 kuthetha ukuba intambo yentambo ayiqinile uthuli kwaye inokumelana nokuntywiliselwa ngokuqhubekayo emanzini, iyenze ilungele ukusetyenziswa phantsi kwamanzi.
4. Vavanya iimfuno zoomatshini
Ukongeza kwizinto ezisingqongileyo, iimfuno zoomatshini zesicelo nazo kufuneka ziqwalaselwe. Oku kubandakanya i-diameter yekhebula, uhlobo lwekhebula elisetyenzisiweyo, kunye nokukwazi ukuxinzelela ngomatshini. Qinisekisa ukuba i-cable gland ekhethiweyo inokuthatha ubungakanani bentambo kwaye ibonelele ngokufanelekileyo ukukhululeka koxinzelelo ukukhusela umonakalo wentambo.
5. Ukuthotyelwa kunye nemigangatho
Ekugqibeleni, qiniseka ukuba i-cable glands ihambelana nemigangatho yeshishini elifanelekileyo kunye nemimiselo. Oku kunokubandakanya iziqinisekiso ezifana ne-UL (Underwriters Laboratories), i-CE (CE Mark Europe), okanye i-ATEX (iSiqinisekiso se-Atmospheres eqhumayo). Ukuthotyelwa kwale migangatho kuqinisekisa ukuba i-cable glands ihlangabezana neemfuno zokhuseleko kunye nokusebenza kwesicelo sakho esithile.
ukuququmbela
Ukukhetha okulungileyoidlala lentamboimathiriyeli yesicelo sakho ibalulekile kwaye inefuthe kukhuseleko nokuthembeka kofakelo lwakho lombane. Ngokuqonda isicelo sakho, ukuqwalasela iipropati zezinto ezahlukeneyo, ukuvavanya iimfuno zokusingqongileyo kunye noomatshini, kunye nokuqinisekisa ukuthotyelwa kwemigangatho yoshishino, unokukhetha ngokufanelekileyo i-cable gland ehlangabezana neemfuno zakho. Ukuthatha ixesha lokwenza ukhetho olunolwazi ekugqibeleni luya kuphucula ukusebenza kunye nobomi benkqubo yakho yombane.
