Emazweni ahlukahlukene emhlabeni jikelele, kunesidingo sokuthuthukiswa kwezolimo kanye nokugeleza kwamanzi emadolobheni, futhi amaphampu amanzi ayimikhiqizo ebalulekile. Ngakho-ke, iphampu yamanzi yenjini kaphethiloli ngaphansi kwe-Ouyixin Electromechanical nayo ingahlangabezana ngokunembile nalesi sidingo.
Iphampu yamanzi yenjini kaphethiloli iyiphampu ye-centrifugal. Isimiso sokusebenza sephampu ye-centrifugal ukuthi lapho iphampu igcwele amanzi, injini ishayela i-impeller ukuthi ijikeleze, ikhiqize amandla aphakathi.
