A lokacin kula da na'urar samar da injinan ...
Ana iya raba hatimin aiki na injin turbin hydraulic zuwa:
(1) Hatimin lebur. Hatimin lebur ɗin ya haɗa da hatimin lebur ɗin labule ɗaya mai faɗi da hatimin lebur ɗin labule biyu. Hatimin lebur ɗin labule ɗaya mai faɗi yana amfani da faranti na roba mai faɗi ɗaya don samar da hatimin tare da ƙarshen fuskar zoben bakin ƙarfe mai juyawa a kan babban shaft. An rufe shi da matsin ruwa. Tsarinsa mai sauƙi ne, amma tasirin hatimin bai yi kyau kamar na hatimin farantin lebur ɗin labule biyu ba, kuma tsawon aikinsa bai kai na hatimin farantin lebur ɗin labule biyu ba. Faranti mai faɗi mai faɗi biyu yana da kyakkyawan tasirin hatimin, amma tsarinsa yana da rikitarwa kuma ruwa yana ɗigawa lokacin ɗagawa. A halin yanzu, ana amfani da shi a cikin ƙananan da matsakaici na axial-flow raka'a.
(2) Hatimin Radial. Hatimin Radial ya ƙunshi tubalan carbon da yawa masu siffar fanka da aka matse su sosai a kan babban ramin ta hanyar maɓuɓɓugan ruwa a cikin tubalan da ke siffar ƙarfe don samar da wani yanki na hatimi. Ana buɗe ƙaramin ramin magudanar ruwa a cikin zoben hatimi don fitar da ruwan da ya zube. Yawanci ana rufe shi da ruwa mai tsabta, kuma juriyarsa ba ta da kyau a cikin laka da ke ɗauke da ruwa. Tsarin hatimin yana da rikitarwa, shigarwa da kulawa suna da wahala, aikin bazara ba shi da sauƙin tabbatarwa, kuma daidaita kansa na radial bayan gogayya ƙarami ne, don haka an kawar da shi kuma an maye gurbinsa da hatimin fuska na ƙarshe.
(3) Hatimin marufi. Hatimin marufi ya ƙunshi zoben hatimi na ƙasa, marufi, zoben hatimin ruwa, bututun hatimin ruwa da gland. Yana taka rawa wajen rufewa ta hanyar marufi a tsakiyar zoben hatimi na ƙasa da hannun matse gland. Ana amfani da hatimin sosai a ƙananan na'urori masu kwance.
(4) Hatimin fuska. Hatimin fuska * * * nau'in inji da nau'in hydraulic. Hatimin fuska na ƙarshen injiniya ya dogara ne akan maɓuɓɓugar ruwa don ɗaga faifan da aka sanya masa toshe roba mai zagaye, don haka toshe roba mai zagaye yana kusa da zoben bakin ƙarfe da aka gyara akan babban shaft don taka rawar rufewa. An sanya zoben rufe robar a saman murfin (ko murfin tallafi) na injin turbin hydraulic. Irin wannan tsarin rufewa yana da sauƙi kuma mai sauƙin daidaitawa, amma ƙarfin bazara ba shi da daidaito, wanda ke da saurin ɗaurewa, lalacewa da aikin rufewa mara ƙarfi.
(5) Hatimin zoben labyrinth. Hatimin zoben labyrinth sabon nau'in hatimi ne a cikin 'yan shekarun nan. Ka'idar aikinsa ita ce a sanya na'urar farantin famfo a saman mai gudu na turbine. Saboda tasirin tsotsar farantin famfo, babban flange na shaft koyaushe yana cikin yanayi. Babu hulɗa tsakanin shaft da hatimin shaft, kuma akwai kawai Layer na iska. Hatimin yana da tsawon rai mai tsawo. Babban hatimin shaft nau'in labyrinth ne wanda ba ya taɓawa, wanda ya ƙunshi hannun riga mai juyawa kusa da shaft, akwatin rufewa, babban bututun magudanar ruwa na hatimin shaft da sauran abubuwan haɗin gwiwa. A ƙarƙashin aikin turbine na yau da kullun, babu matsin ruwa a kan akwatin rufewa a cikin dukkan kewayon kaya. Farantin famfo akan mai gudu yana juyawa tare da mai gudu don hana ruwa da daskararru shiga babban hatimin shaft. A lokaci guda, bututun magudanar ruwa na farantin famfo yana hana yashi ko abubuwa masu ƙarfi taruwa a ƙarƙashin murfin saman injin turbin ruwa, kuma yana fitar da ƙaramin adadin ruwan da ke kwarara ta hanyar zoben dakatarwar sama zuwa ruwan wutsiya ta hanyar bututun magudanar ruwa na farantin famfo.
Waɗannan su ne manyan rukunoni huɗu na hatimin turbine. A cikin waɗannan rukunoni huɗu, hatimin zobe na labyrinth, a matsayin sabuwar fasahar hatimi, zai iya hana kwararar ruwa a kan akwatin hatimi yadda ya kamata, wanda tashoshin wutar lantarki da yawa suka yi amfani da shi kuma suka yi amfani da shi, kuma tasirin aiki yana da kyau.
