Uhlolo oluqhelekileyo kufuneka luquke ukujonga ngokubonakalayo izinto zokwambathisa ubushushu, ii-arc chutes, kunye neendlela zokusebenza. Iindawo zoomatshini kufuneka zihlolwe ukuba zishukuma kakuhle kwaye zilungelelaniswe kakuhle, ngelixa uqhagamshelo lombane kufuneka luhlolwe ukuba alunanto okanye iimpawu zobushushu obuphezulu. Ucoceko nalo lubalulekile, njengoko uthuli kunye nenkunkuma zinokuchaphazela kakubi ukwambathisa ubushushu kwaye ziphazamise ukusebenza.

3. Iindlela zoVavanyo oluSebenzayo kunye noQinisekiso lokuSebenza

Uvavanyo olusebenzayo luqinisekisa ukuba iindlela zokukhusela zisebenza ngokuchanekileyo phantsi kweemeko ezilinganisiweyo. Oku kuquka uvavanyo lokusebenza koomatshini, ukuqinisekiswa komsebenzi wohambo, kunye novavanyo lwexesha lokuphendula. Uvavanyo luqinisekisa ukubaIsixhobo sokwaphula isekethe yomoya (i-ACB)ingaphendula ngokuchanekileyo kwiimeko zokugqithisa okanye iimeko ze-short-circuit kwaye ihambelane ngokufanelekileyo nezinye izixhobo zokukhusela kwinkqubo.

4. Iingxaki zoLondolozo oluQhelekileyo kunye namaqhinga okusombulula iingxaki

Iingxaki eziqhelekileyo ziquka ukukhukuliseka koqhagamshelwano, ukuguguleka koomatshini, kunye nokuziphatha okungafanelekanga kokukhubeka. Ezi ngxaki zinokubangelwa kukutshintsha rhoqo imisebenzi, amanqanaba aphezulu eempazamo, okanye ukunganeli kwamaxesha okulungisa. Ukujongana neengxaki ezinjalo ngokukhawuleza ngokulungisa, ukulungisa, okanye ukutshintshwa kwecandelo kunceda ukubuyisela ukusebenza okuqhelekileyo kwaye kuthintele iimpazamo ezinkulu zenkqubo.

5. Amanyathelo okhuseleko kunye namaxwebhu ngexesha lokugcinwa kwe-ACBe

Ukhuseleko lubaluleke kakhulu ngexesha lemisebenzi yokulungisa. Kufuneka kulandelwe iinkqubo ezifanelekileyo zokutshixa nokukhupha umbane ngaphambi kokuhlolwa okanye ukuvavanywa. Iirekhodi zolondolozo, iziphumo zovavanyo, kunye neengxelo zokuhlolwa kufuneka zibhalwe ngononophelo ukuxhasa ukuthotyelwa kwemigangatho yokhuseleko kunye nokubonelela ngembali ecacileyo yolondolozo. Amaxwebhu ahambelanayo akwanceda ukuphucula ucwangciso lolondolozo lwexesha elizayoIsixhobo sokwaphula isekethe yomoya (i-ACB).

Isiphelo

Ukugcinwa novavanyo olusebenzayo kubalulekile ukuqinisekisa ukusebenza okuthembekileyo kwezixhobo zokukhusela amandla ezisebenzisa umbane ophantsi. Ngokusebenzisa iinkqubo zokuhlola ezicwangcisiweyo, uvavanyo olusebenzayo, kunye neendlela ezifanelekileyo zokubhala amaxwebhu, izixhobo zinokuphucula kakhulu ukuthembeka kwenkqubo kunye nokhuseleko. Indlela yokulungisa eqeqeshekileyo ekugqibeleni ixhasa ukuqhubeka kokusebenza kwexesha elide kunye nokuqina kwenkqubo yombane.
