Isiguquli se-SZH esiwuchungechunge lwe-gas-liquid damping sisebenzisa ubuchwepheshe obuthuthukisiwe bokuguqula uketshezi lwegesi kusilinda saso somoya, esingaguqula amandla omoya abe amandla omshini futhi sizuze ukulawula isivinini esinembile nokulawula isikhundla ngesilawuli esimanzisa amanzi.Lolu hlobo lwesiguquli lunezici zokuphendula okusheshayo, ukunemba okuphezulu, nokuthembeka okuqinile, okungahlangabezana nezidingo zokulawula ukunyakaza ngaphansi kwezimo ezihlukahlukene zokusebenza eziyinkimbinkimbi.
