Imininingwane enzuzo
Indlela yokuthumela:Iposi, ukuthutha ngendiza, ukuthutha ngomkhumbi
Ukubonisa umlingani
Idizayinelwe imishini yokusika ngamanzi yezinsimbi eziyizigaxa ezinkulu ezimbonini zensimbi. Yenziwe ngensimbi ekhethekile yokwenza amathuluzi enezinga eliphezulu lokushuba futhi iqiniswe ngokwelashwa okushisayo okungaphansi kwe-vacuum. Umkhiqizo unamandla okumelana nokushisa okuphezulu nokumelana nomthelela okungcono kakhulu. Awuthambekele ekuqhekekeni emaphethelweni lapho usika izigaxa zensimbi ezinkulu, unokumelana nokugqoka okuhle kakhulu nempilo yokusebenza ende. Njengoba inobukhulu bokwenziwa obunembile, ubukhulu obuhlukahlukene obukhethekile bungafakwa ngokwezidingo ukuze kuhlangatshezwane nezidingo zokusebenza okuqhubekayo okunamandla aphezulu emigqeni yokukhiqiza insimbi.
