Umsesane womhlaba we-MTE19201216
Umsesane wokumisa umi njengokhuseleko olubalulekileyo kunye necandelo lokukhusela elisetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo zemizi-mveliso kunye nezombane, kunye nokusebenza kwayo okungundoqo kugxile ekunciphiseni iingozi zombane ezinokubeka esichengeni imfezeko yezixhobo kunye nokhuseleko lokusebenza. Indima yayo ephambili yokuphambukisa imisinga yokuvuza ibaluleke kakhulu kunolawulo olulula lwangoku-ukuvuza kwemisinga, okuhlala kuvela ekuthotyweni kwe-insulation, ukunxitywa kwecandelo, okanye iziphene zombane ezingalindelekanga kwiinkqubo ezinjengeenjini, iijenereyitha, okanye izixhobo zombane ophezulu, zibeka umngcipheko omkhulu ukuba zishiywe zingaqwalaselwa. Le misinga ilahlekileyo ayinakuvusa kuphela ii-alam zobuxoki kwiinkqubo zokubeka iliso kodwa ikwakhokelela ekutshiseni ngokugqithisileyo kwezixhobo zombane, ukophuka kwe-insulation ekhawulezileyo, kunye neengozi zomlilo ezinokubakho. Iringi yokumisa isebenza njengendlela ezinikeleyo, yokuxhathisa okuphantsi kule misinga yokuvuza, iwahambisa ngokukhuselekileyo emhlabeni okanye kwinkqubo emiselweyo yokumisa endaweni yokuvumela ukuba ihambe ngeendlela ezingacetywanga (ezinje ngeendawo ezivalekileyo zentsimbi, iintambo zeengcingo, okanye izixhobo ezikufuphi), ngaloo ndlela ikhusela zombini inkqubo yombane ngokwawo kunye nabasebenzi abanokuthi bangene kumphezulu ovelileyo.
Umsesane wokumisa ujongana nale ngxaki ngokuseka uxhulumaniso oluthe ngqo, oluphantsi lombane olune-impedance phakathi kweshaft ejikelezayo kunye nesakhelo esimileyo sesixhobo (okanye inkqubo yokumisa). Ngokubonelela ngale ndlela inikezelweyo, iringi yokumisa ilingana ngokufanelekileyo amandla ombane kuwo wonke umngxuma kunye neebheringi, ukuthintela ukwakhiwa kombane we-shaft onokuthi ukhokelele kwimisinga eyingozi yokuthwala. Lo msebenzi wokukhusela ubaluleke kakhulu kwiinkqubo zombane eziphezulu okanye eziphezulu-ezifana nezo zisetyenziselwa ukuvelisa, ukuveliswa kwamandla, okanye umatshini onzima-apho nokuba umonakalo omncinci wokuthwala unokwenyuka ube yingxaki enkulu yokusebenza okanye imingcipheko yokhuseleko.
