Umgaqo osebenzayo wokwahlula amanzi
Kuhlala kukho abantu abaninzi abangabaziyo emangalisayo ebomini, kwaye kukho izinto ezinxulumene ngokusondeleyo ebomini, ezifana umgangatho ukufudumeza manifold.Water umgangatho ukufudumeza kwakhona inkqubo yokufudumeza umgangatho.Enye yamasebe omgangatho wokufudumeza isahluli samanzi sisixhobo esingundoqo esifakwe kwinkqubo yokufudumeza umgangatho ukudibanisa umbhobho oyintloko wokufudumeza, umbhobho wokuhambisa amanzi kunye nombhobho wokubuyisela.
Umgangatho wokufudumeza umhluli wamanzi unokwahlulwa ngokurhabaxa ube ngamacandelo amabini ahlukeneyo, isahluli samanzi kunye nomqokeleli wamanzi, ngokomsebenzi wokungena kwamanzi kunye ne-return.Imisebenzi nayo ihluke.Imisebenzi emine ephambili kukwandiswa, ukuchithwa, kunye nokuzinzisa. Kwaye ukuphambukisa, ukwenzela ukufudumeza umgangatho, ikakhulu ukuhlangabezana neemfuno zonikezelo lwamanzi kunye nokuthutha.Ukuba uhlalutya umgaqo osebenzayo womgangatho wokufudumeza isahluli samanzi ngokwethiyori, ayikwazi ukulawula ubushushu bangaphakathi, kodwa kunokwenzeka kwiprakthikhali.Isahluli samanzi esifudumeza emgangathweni sahlula amanzi ashushu okanye umphunga othunyelwe kumbhobho wokufudumeza ophambili kwimibhobho encinci. Ukuhamba, ukuba uvula ukuhamba kwamanzi ngokupheleleyo, ukujikeleza kuya kukhawuleza, kwaye ubushushu bangaphakathi buya kuba phezulu, kodwa ukuba ivalve nganye ivuleke ngesiqingatha, okanye i-valve enye ivuliwe, ivalve yakho enesiqingatha-evulekileyo iyalawulwa. Ukuhamba kwamanzi kumbhobho kuncinci, ukuhamba kwamanzi kuyacotha, kwaye ubushushu obungaphakathi ngaphakathi buphantsi. I-manifold inokulawula ubushushu bangaphakathi, ngoko ke owona msebenzi uphambili wokufudumeza umgangatho kukulawula ubushushu bangaphakathi.
