Ukukhetha iswishi yomkhawulo efanele kubalulekile ukuqinisekisa ukusebenza kahle nokuphepha ezinhlelweni ezahlukene zezimboni. Amaswishi omkhawulo angamadivayisi kagesi asetshenziselwa ukubona ukuba khona noma ukungabikho kwento futhi anikeze impendulo ezinhlelweni zokulawula. Avame ukusetshenziswa ezinhlelweni zokwenza izinto ngokuzenzakalela, ukukhiqiza, kanye nokulawula izinqubo ukuqapha nokulawula ukunyakaza kwemishini nemishini. Kulo mhlahlandlela, sizochaza izinto ezibalulekile okufanele uzicabangele lapho ukhetha iswishi yomkhawulo.
Izimo Zemvelo:
Into yokuqala okufanele icatshangelwe lapho ukhetha iswishi yomkhawulo yizimo zemvelo lapho izosetshenziswa khona. Izindawo ezahlukene zingadala izinselele ezifana namazinga okushisa aphezulu, umswakama, uthuli, ukudlidliza, noma ukuchayeka kumakhemikhali. Qinisekisa ukuthi iswishi yomkhawulo yenzelwe ukumelana nezimo ezithile zemvelo zesicelo. Bheka iziswishi ezinezilinganiso ezifanele zemvelo, njengezilinganiso ze-IP (Ingress Protection) zokumelana nothuli nomswakama, noma izilinganiso ze-NEMA (National Electrical Manufacturers Association) zokuvikela imvelo.
Isivinini Sokusebenza Namandla:
Cabanga ngesivinini sokusebenza kanye namandla adingekayo kuhlelo lwakho lokusebenza. Amanye amaswishi omkhawulo aklanyelwe izinhlelo zokusebenza zesivinini esikhulu, kanti amanye afaneleka kakhulu ekusebenzeni okuhamba kancane noma okunzima. Nquma isivinini lapho into noma umshini uzohamba khona bese ukhetha iswishi yomkhawulo engaphendula ngokunembile nangokuthembekile ngaphakathi kwalelo banga lesivinini. Ngokufanayo, cabanga ngamandla noma ingcindezi iswishi ezohlangana nayo bese uqinisekisa ukuthi ingakwazi ukusingatha umthwalo odingekayo.
Isishintshi Somkhawulo We-Plunger Esivaliwe
Uhlobo lwe-Actuator:
Ama-Limit switch afika nezinhlobo ezahlukene zama-actuator, okuyizindlela ezenza ukuthintana ngokomzimba nento ezwayo. Izinhlobo ezivamile zama-actuator zifaka phakathi i-plunger, i-roller lever, i-whisker, i-rod lever, kanye ne-spring-loaded. Ukukhetha uhlobo lwe-actuator kuncike ezintweni ezifana nesimo, usayizi, kanye nokunyakaza kwento ezotholakala. Cabanga ngezici zomzimba zento bese ukhetha i-actuator ezonikeza ukuthintana okuthembekile nokungaguquguquki.
Ukucushwa Koxhumana Nathi:
Amaswishi omkhawulo anikeza ukucushwa okuhlukile kokuxhumana, okuhlanganisa oxhumana nabo abavame ukuvula (CHA), abavame ukuvalwa (NC), kanye nokushintsha (CO). Ukucushwa koxhumana nabo kunquma isimo seswishi uma singavuselelwanga nokuthi sivuselelwa nini. Khetha ukucushwa koxhumana nabo okufanele ngokusekelwe ezidingweni zohlelo lwakho lokusebenza kanye nokuziphatha okufiselekayo kohlelo lokulawula.
Izilinganiso Zikagesi:
Hlola izilinganiso zikagesi zeswishi yomkhawulo ukuqinisekisa ukuhambisana nohlelo lwakho lukagesi. Cabangela izici ezifana ne-voltage, i-current, kanye nomthamo wokushintsha omkhulu. Qinisekisa ukuthi iswishi ingaphatha umthwalo kagesi kanye namazinga e-voltage adingwa yisicelo sakho. Naka umthamo wokushintsha omkhulu ukuze uvimbele umonakalo noma ukwehluleka kwangaphambi kwesikhathi kweswishi lapho uphatha ama-current noma ama-voltage aphezulu.
Izinketho Zokufaka Nokuxhuma:
Cabanga ngezinketho zokufaka nokuxhuma ezitholakalayo zeswishi yomkhawulo. Izinhlobo ezivamile zokufaka zifaka phakathi ukufakwa kwephaneli, ukufakwa kwendawo, kanye nokufakwa kwesitimela se-DIN. Khetha inketho yokufaka efanela izidingo ezithile zokufaka kanye nendawo etholakalayo. Ngaphezu kwalokho, cabanga ngezinketho zokuxhuma, njengezikulufo noma izikulufo ezisheshayo, bese ukhetha leyo elula kakhulu ekusethweni kwakho kwezintambo.
Ukuphepha kanye nesitifiketi:
Uma isicelo sakho sihilela imisebenzi ebalulekile yokuphepha noma ukuhambisana nezindinganiso ezithile zemboni, qiniseka ukuthi ukushintsha komkhawulo kuhlangabezana nezidingo zokuphepha nezitifiketi ezidingekayo. Funa ukushintsha okuqinisekiswe yizinhlangano eziqashelwayo noma okuhambisana nezindinganiso zemboni njenge-UL (Underwriters Laboratories), i-CE (Conformité Européene), noma i-IEC (International Electrotechnical Commission).
Ukuthembeka Nokuqina:
Ukuthembeka nokuqina kuyizinto ezibalulekile lapho ukhetha iswishi yomkhawulo. Funa amaswishi avela kubakhiqizi abadumile abaziwayo ngokukhiqiza imikhiqizo esezingeni eliphezulu nethembekile. Cabanga ngobude besikhathi sokusebenza esilindelekile seswishi kanye nanoma yiziphi izidingo zokulungisa. Ngaphezu kwalokho, hlola izici ezifana nokuvikelwa kokukhuphuka okwakhelwe ngaphakathi, oxhumana nabo abazihlanzayo, noma izinketho zokuvala ukuqinisekisa ukuthembeka kwesikhathi eside nokunciphisa isikhathi sokungasebenzi.
Izici eziqondene nohlelo lokusebenza:
Kuye ngezidingo zakho ezithile zohlelo lokusebenza, cabanga nganoma yiziphi izici ezengeziwe noma imisebenzi engaba wusizo. Isibonelo, amanye amaswishi omkhawulo anikeza izinkomba ze-LED zokubonisa isimo sokubonakala, ukuzwela okulungisekayo kokulungiswa kahle, noma izinketho zokuxhuma ukuze kube lula ukufaka. Hlola izidingo zohlelo lwakho lokusebenza bese uthola noma yiziphi izici ezengeziwe ezingathuthukisa ukusebenza kanye nokusebenza kweswishi yomkhawulo.
Izinto Okucatshangelwayo Ngezindleko:
Nakuba izindleko kungafanele kube yisona sici esinqumayo kuphela, kubalulekile ukucabangela isabelomali sephrojekthi yakho. Qhathanisa amanani nezici phakathi kokushintsha okulinganiselwe okuhlukene ukuze uthole ibhalansi engcono kakhulu phakathi kwezindleko nokusebenza. Khumbula ukubeka phambili ikhwalithi, ukuthembeka, kanye nokuhambisana nezidingo zohlelo lwakho lokusebenza kunokugxila kuphela entengweni.
Ekuphetheni, ukukhetha iswishi yomkhawulo efanele kuhilela ukucabangela izici ezifana nezimo zemvelo, isivinini sokusebenza kanye namandla, uhlobo lwe-actuator, ukucushwa kokuxhumana, izilinganiso zikagesi, izinketho zokufaka kanye nokuxhumeka, ukuphepha kanye nesitifiketi, ukuthembeka kanye nokuqina, izici ezithile zesicelo, kanye nokucatshangelwa kwezindleko. Ngokuhlola ngokucophelela lezi zici nokukhetha iswishi yomkhawulo ehambisana nezidingo zakho ezithile, ungaqinisekisa ukusebenza kahle, ukuphepha, kanye nokusebenza kahle ezinhlelweni zakho zokusebenza zezimboni.
