(3) Shirya hatimin.Hatimin shiryawa ya ƙunshi zoben hatimin ƙasa, shiryawa, zoben hatimin ruwa, bututun hatimin ruwa da gland.Yana taka muhimmiyar rawa ta hanyar haɗawa a tsakiyar zoben hatimin ƙasa da hannun rigar matsewa.Ana amfani da hatimin ko'ina a cikin ƙananan raka'a a kwance.
(4) Rubutun fuska.Hatimin fuska * * * nau'in injina da nau'in hydraulic.Hatimin ƙarshen fuska na injina ya dogara da bazara don cire diski ɗin da aka sanye da shingen roba madauwari, ta yadda shingen roba madauwari ya kasance kusa da zoben bakin karfe da aka kafa akan babban ramin don taka rawar rufewa.Ana gyara zoben rufewa na roba akan saman murfin (ko murfin goyan baya) na injin turbine.Irin wannan tsarin rufewa yana da sauƙi kuma mai sauƙi don daidaitawa, amma ƙarfin bazara ba daidai ba ne, wanda ke da wuyar haɗuwa da eccentric, lalacewa da rashin kwanciyar hankali.
(5) Hatimin zobe na Labyrinth.Hatimin zobe na Labyrinth sabon nau'in hatimi ne a cikin 'yan shekarun nan.Ka'idar aikinsa ita ce an saita na'urar farantin famfo a saman mai gudu turbine.Saboda tasirin tsotsa na farantin famfo, babban shaft flange koyaushe yana cikin yanayi.Babu lamba tsakanin shaft da hatimin shaft, kuma akwai kawai Layer na iska.Hatimin yana da tsawon rayuwar sabis.Babban hatimin hatimi shine nau'in labyrinth mara lamba, wanda ya ƙunshi hannun hannu mai juyawa kusa da shaft, akwatin rufewa, babban bututun hatimin hatimin magudanar ruwa da sauran abubuwa.A ƙarƙashin aikin yau da kullun na injin turbine, babu matsa lamba na ruwa akan akwatin rufewa a cikin kewayon nauyin duka.Farantin famfo a kan mai gudu yana juyawa tare da mai gudu don hana ruwa da daskararru daga shiga babban hatimin shaft.A lokaci guda kuma, bututun magudanar ruwa na farantin famfo yana hana yashi ko ƙaƙƙarfan abubuwa taruwa a ƙarƙashin murfin saman injin injin ɗin, kuma yana fitar da ɗan ƙaramin ɗigon ruwa ta cikin zoben tsayawa na sama zuwa ruwan wutsiya ta bututun magudanar ruwa. na famfo farantin.
Waɗannan su ne manyan nau'ikan nau'ikan injin turbine guda huɗu.A cikin waɗannan nau'ikan nau'ikan guda huɗu, hatimin zobe na labyrinth, a matsayin sabuwar fasahar hatimi, na iya yin tasiri yadda ya kamata ya hana zubar ruwa a cikin akwatin rufewa, wanda yawancin tashoshin wutar lantarki suka karɓe kuma ana amfani da su, kuma tasirin aiki yana da kyau.
