Ingaphakathi lombhobho we uhlaka lwejethi yamanzi isesekeli simise okwendandatho. Intambo ye-weft yethulwa isuka eshubhuni yomhlahlandlela we-weft eduze nendawo ye-axial, futhi amanzi anomfutho ophezulu ageleza esuka emzimbeni we-nozzle, futhi alungiswe umkhono wokulungisa ukuze kuncishiswe isimo se-vortex sendiza futhi kuthuthukiswe ukuhlangana kwayo. Lapho i-jet ikhishwa emgodini we-nozzle, kuncike emandleni okungqubuzana phakathi kokugeleza kwamanzi kanye nentambo ye-weft, intambo yokufaka i-weft izodlula eshedini. I-Nozzle ingenye yezingxenye ezibalulekile zezesekeli zejethi yamanzi, futhi ukuhlanganisa kwayo kuhlobene eduze nokusebenza kokulukwa kokufakwa kwe-jet weft yamanzi.
Ububanzi bombhobho wendandatho bungalungiswa ngokuhambisana nokucoleka nokuhlukahluka kwentambo ye-weft. Ukuzungezisa ishubhu lomhlahlandlela we-weft futhi ulungise indawo yalo ehlobene nomzimba we-nozzle 3 kungashintsha indawo eyi-annular yokuvula umlomo wombhobho. Imibhobho ye-jet looms yamanzi yenziwe ngensimbi engagqwali kanye ne-ceramics. Zinezidingo eziphakeme zokushelela kwe-conical cavity yangaphakathi nodonga lwangaphandle, futhi zinezidingo eziphakeme zokugxila komzimba we-nozzle kanye nomhlahlandlela we-weft, ikakhulukazi lapho ulungisa ububanzi bombhobho. Ngalesi sikhathi, ukuchezuka kwe-concentricity kuzothinta kakhulu indlela yokuhlanganisa nokufutha yokugeleza kwamanzi, futhi kwenze ukusebenza kwejethi yamanzi kube kubi kakhulu.
Isivinini sejethi endaweni yokukhipha umbhobho wezinsiza zokuluka ijethi yamanzi sinqunywa ukucindezela kwamanzi. Uma umfutho wamanzi uphezulu, isivinini sejethi endaweni yokuphuma siphezulu. Njengoba ukumelana kwendiza yamanzi kuhambisana nesikwele sejubane layo lejethi, lapho isivinini sejethi siphezulu endaweni yokukhipha umlomo, yilapho indiza izokwehla ngokushesha ngemva kokundiza. Lapho ijubane eliphambi kwejethi lehla ngaphansi kwejubane lentambo ye-weft, izohamba eduze kwentambo ye-weft ekugcineni, kuyilapho intambo ye-weft elandelayo isathuthuka ngesivinini esikhulu, okuholela ekuncipheni kwe-weft " ukuphithizela phambili nokucindezela ngemuva". Ngakho-ke, kubaluleke kakhulu ukukhetha ukucindezela kwamanzi kanye nesivinini sokuqala se-jet ngokunengqondo.
Nakuba i-viscosity yamanzi inkulu kakhulu kunomoya, ngemva kokuba i-jet ishiya umlomo wombhobho, iyakhula ibe yi-conical shape; ijethi lamanzi elinembile elifuthwe ngombhobho onobubanzi obungu-2-3mm, ngemva kokundiza okungu-1. 8m, ububanzi bayo buba ngu-20mm. Ngenxa yethonya lamandla adonsela phansi, i-axis yejethi yamanzi iyi-parabola, ngakho-ke i-axis yomlomo kufanele ihlehliselwe phezulu nge-engeli efanele.
