Emkhakheni wokuphathwa kwemithombo yamanzi, amamitha amanzi asebenza ngomshini asebenza njengesixazululo esithembekile nesivivinywe isikhathi eside sokulandelela ukusetshenziswa kwamanzi. Ngokungafani nozakwabo be-elekthronikhi noma abahlakaniphile, la madivayisi asebenzisa izingxenye zemishini ukukala amazinga okugeleza kwamanzi, enikeza ukuqina, ukusebenza kahle kwezindleko, kanye nobulula obuwenza abe yinto ebalulekile ezindaweni zokuhlala, zezentengiselwano, kanye nezezimboni. Sekungamashumi eminyaka, abe yinto ekhethwa kakhulu yizinsizakusebenza, abaphathi bezindawo, kanye nabaninikhaya, bevala igebe phakathi kokulinganisa okunembile kanye nokusetshenziswa okusebenzayo.
Enhliziyweni yemitha yamanzi yomshini kukhona isimiso sokusebenza esiqondile kodwa esisebenzayo: siguqula amandla e-kinetic amanzi agelezayo abe ukunyakaza komshini, okube sekuhunyushwa kube amayunithi alinganiswayo evolumu (ngokuvamile amamitha ama-cubic noma amagaloni). Izingxenye ezibalulekile eziqhuba le nqubo zifaka phakathi igumbi lokulinganisa, ama-impeller noma ama-turbine, isitimela segiya, kanye nerejista. Lapho amanzi edlula kumitha, ajikeleza i-impeller (i-rotor encane, enezinti) noma i-turbine—ngejubane lokujikeleza elihambisana ngqo nesilinganiso sokugeleza kwamanzi. Lokhu kunyakaza kokujikeleza kudluliselwa ngesitimela segiya kuya kurejista, isibonisi se-dial noma sedijithali esiqopha inani eliphelele lamanzi asetshenzisiwe.
Izinhlobo ezimbili eziyinhloko zamamitha amanzi anomshini zibusa emakethe, ngayinye iklanyelwe izimo ezithile zokugeleza: amamitha okuhambisa amanzi amahle kanye namamitha ejubane. Amamitha okuhambisa amanzi amahle (ngokuvamile abizwa ngokuthi “amamitha e-nutating disc”) ahamba phambili ezindaweni zokugeleza eziphansi kuya kweziphakathi, njengezindlu zokuhlala. Asebenzisa idiski ejikelezayo ebamba amanzi amaningi njengoba ejikeleza, ukuqinisekisa ukulinganiswa okunembile ngisho nangamazinga okugeleza ahamba kancane—afanele ukulandelela ukusetshenziswa kwansuku zonke njengama-drip empompi noma ukugijima kweshawa. Ngakolunye uhlangothi, amamitha ejubane (kufaka phakathi amamitha e-turbine kanye nama-jet amaningi) aklanyelwe amazinga aphezulu okugeleza ezakhiweni zezentengiselwano, ezimbonini, noma ezinhlelweni zokunisela. Amamitha e-turbine asebenzisa isondo le-turbine elijikelezayo, kuyilapho amamitha e-jet amaningi eqondisa amanzi ngama-jet amaningi ukuze ajikeleze i-impeller, kokubili enikeza ukufundwa okusheshayo nokunembile kwezimo ezifunwa kakhulu.
Elinye lamandla amakhulu amamitha amanzi omshini ukuqina kwawo kanye nokugcinwa kwawo okuphansi. Akhiwe ngezinto eziqinile njengethusi, insimbi ephonswe, noma ipulasitiki yezinga eliphezulu, ayamelana nokugqwala nokuguguleka, ngisho nasezimweni zamanzi ezinzima (isb., amanzi aqinile noma inhlabathi encane). Ngokungafani namamitha kagesi, awanawo amabhethri okushintsha noma amabhodi wesekethe okulungisa, okunciphisa izindleko zokusebenza zesikhathi eside. Imitha yomshini efakwe kahle ingahlala iminyaka engu-15-20, okwenza kube utshalomali olusebenzisa izindleko eziphansi kubanikazi bezindawo kanye nezinsizakusebenza.
Ubulula bungenye inzuzo ecacile. Amamitha omshini awadingi umthombo wamandla wangaphandle—asebenza kuphela ngamandla amanzi agelezayo—okususa ingozi yokuphazamiseka kukagesi okuphazamisa ukulinganisa. Ukwakheka kwawo kwenza kube lula ukuwafaka nokuhlola: amamodeli amaningi afanelana nosayizi wamapayipi ajwayelekile (isb., ½ intshi kuya ku-2 intshi ukusetshenziswa ekhaya), futhi irejista ibonakala ngokushesha, okuvumela ukufundwa okusheshayo ngesandla noma ukuhlanganiswa nezinhlelo zokufunda ezizenzakalelayo eziyisisekelo (ama-AMR) ngezinzwa zamagnetic.
Nakuba amamitha ahlakaniphile athole ukuthandwa eminyakeni yamuva ngenxa yamakhono awo edatha yesikhathi sangempela, amamitha amanzi emishini asabalulekile ngenxa yokungabizi kwawo nokuthembeka kwawo. Abaluleke kakhulu ezindaweni ezinengqalasizinda elinganiselwe yobuchwepheshe obuhlakaniphile, noma kubasebenzisi abafuna ikhambi lokulinganisa elingenazinkinga, elingenangozi ephansi. Ngezinsizakusebenza, zinikeza ibhalansi yokunemba nezindleko, ziqinisekisa ukukhokhiswa okufanele ngaphandle kwesidingo sokuthuthukiswa kwedijithali okubizayo.
Ekuphetheni, amamitha amanzi asebenza ngomshini awawona nje amadivayisi okulinganisa ukusetshenziswa kwamanzi—ayisisekelo sokuphathwa kwamanzi okusimeme. Izindlela zawo ezilula, isikhathi eside sokuphila, kanye nokusebenza kahle kwezindleko kuzenza zibe ukukhetha okusebenzayo kwezicelo ezahlukahlukene, kusukela emakhaya omndeni owodwa kuya emabhizinisini amancane. Njengoba umhlaba uqhubeka nokubeka phambili ukongiwa kwamanzi, la mamitha angaphelelwa yisikhathi azohlala eyithuluzi elibalulekile, esebenza buthule ngemuva kwezigcawu ukuqinisekisa ukulandelwa kokusetshenziswa kwamanzi okusebenzayo nokusobala iminyaka ezayo.
