Umphakeli weyunithi yempendulo uyakukhumbuza ukuthi izimbangela zokwehluleka kwesiguquli sefrikhwensi zihlobene eduze nendawo yokukhiqiza, ikakhulukazi okuhlanganisa okulandelayo:
1. Imbangela yokwehluleka kwesiguquli se-frequency igesi egqwalayo. Abanye abakhiqizi bamakhemikhali banamagesi abolayo kuma-workshops abo, okungaba esinye sezimbangela zokwehluleka kwesiguquli semvamisa, ngale ndlela elandelayo:
(1) Ukungasebenzi kahle kwesiguquli sefrikhwensi kudalwe ukuthintana okungalungile phakathi kweswishi yokuguqula nokudluliswa kwemali ngenxa yamagesi abolayo.
(2) Iphutha lesiguquli semvamisa libangelwa ukujikeleza okufushane phakathi kwamakristalu ngenxa yamagesi agqwalayo.
(3) Ukugqwala kwetheminali kubangele isekethe emfushane kusekethe enkulu, okuholele ekungasebenzini kahle kwesiguquli sefrikhwensi.
(4) Ukugqwala kwebhodi lesifunda kubangela umjikelezo omfushane phakathi kwezingxenye ezihlukahlukene, okuholela ekungasebenzi kahle kwesiguquli semvamisa.
2. Ukungasebenzi kahle kweziguquli zefrikhwensi okubangelwa uthuli olwenziwayo olufana nezinsimbi nothuli. Izinto ezibangela ukwehluleka kokuguqula imvamisa yalolu hlobo zitholakala ikakhulukazi emabhizinisini agxile ekukhiqizeni anothuli oluphezulu njengezimayini, ukucubungula usimende, nezindawo zokwakha.
(1) Uthuli olwedlulele olwedlulele olufana nensimbi lungabangela ukuzungeza okufushane kumjikelezo oyinhloko, okuholela ekungasebenzini kahle kwesiguquli sefrikhwensi.
(2) Uthuli lwavala amaphiko okupholisa, lwawabangela ukuba akhubeke futhi ashise ngenxa yokushisa okuphezulu, okubangele ukungasebenzi kahle kwesiguquli sefrikhwensi.
3. Ukujiya, umswakama, ukuswakama, nezinga lokushisa eliphezulu kungabangela amaphutha kusiguquli samafrikhwensi. Lezi zici ezibangela ukwehluleka kwesiguquli semvamisa kungenxa yesimo sezulu noma izindawo ezikhethekile endaweni yokusetshenziswa.
(1) Ngenxa yomswakama, isigxobo somnyango singashintsha umbala, kubangele ukuthintana kabi futhi kubangele ukungasebenzi kahle kwesiguquli semvamisa.
(2) I-inverter yakhubeka ngenxa yokushisa ngokweqile okubangelwa izinga lokushisa eliphezulu.
(3) Ukungasebenzi kahle kwe-frequency converter kwabangelwa into evuthayo phakathi kwamapuleti ethusi ebhodi lesifunda eliyinhloko ngenxa yomswakama.
(4) Umswakama udala ukugqwala kukagesi kokumelana kwangaphakathi kwesiguquli semvamisa, okuholela ekuqhekekeni kwentambo futhi kubangele ukuthi isiguquli semvamisa singasebenzi.
(5) Ukuminyanisa ngaphakathi kwephepha lokufakwa ngaphakathi kubangela ukuwohloka kokukhishwa, okuholela ekungasebenzini kahle kwesiguquli sefrikhwensi.
Isizathu esiyinhloko sokwehluleka kwesiguquli semvamisa ngenxa yezizathu zomuntu ukukhetha okungalungile kanye nokwehluleka ukulungisa amapharamitha esimweni sokusebenzisa esifanele.
1. Ukukhethwa okungalungile kweziguquli zemvamisa kungabangela ukulayishwa ngokweqile futhi ekugcineni kuholele ekuhlulekeni kokuguqula imvamisa.
2. Amapharamitha awakalungiswa ukuze abe sesimweni sokusetshenziswa esifanele, okuholela ekuvikelweni okuvamise ukudlula i-overcurrent, overvoltage nokunye ukukhubeka kwesiguquli sefrikhwensi, okuholela ekugugeni ngaphambi kwesikhathi kanye nokungasebenzi kahle kwesiguquli sefrikhwensi.
