Hydrocyclone imvura-yemvura yekuparadzanisa michina inowanzoshandiswa kugadzira mvura inogadziriswa muminda yemafuta. Inonyanya kushandiswa kupatsanura iwo emahara madonhwe emafuta akamiswa mumvura kuti asangane nemiyero inodiwa yekuraswa nemirairo. Iyo yakasimba centrifugal masimba anogadzirwa nekudonhedza kudonhedza ndeyekuzadzisa kukurumidza-kumhanya kutenderera kwemvura mudutumuchubhu, nekudaro centrifugally kusundira mvura inorema (mvura) kusvika mukati memukati, nepo mvura yakareruka (mafuta) inosvinwa pakati pedutu chubhu. Nemukati mepressure gradient iyo inobva yasaidzira mvura inorema (mvura) ichifamba ichidzika pasi apo mvura yakareruka (oiri) ichienda kumusoro. Saka nekudaro, zvimedu zvemafuta zvine simba rakareruka rakapatsanurwa kubva kumvura yekudyisa uye kuzadzisa chinangwa chekuparadzaniswa kwemafuta-mvura. Hydrocyclones inoshandiswa zvakanyanya mu petroleum, makemikari indasitiri, kuchengetedza kwezvakatipoteredza uye mamwe minda kana maindasitiri. Vanokwanisa kubata zvinwiwa zvakasiyana-siyana zvine giravhiti yakasiyana, kuvandudza kushanda zvakanaka kwekugadzira uye kuderedza kusvibiswa kwemhepo.
