Ekusebenzeni kwansuku zonke kweSteam Turbine, ngaphezu kokuhlolwa okujwayelekile kokugqoka nokulungiswa, kukhona nezinkomba zokuqapha ezingasiza ukuthi sixwayise ukwehluleka okungaba khona kwendandatho ye-Steam Seal Ring ngaphambi kwesikhathi, ngaleyo ndlela kuvimbele ukuvalwa okungalindelekile. Ngokubheka ngokuqhubekayo lezi zinkomba, ukusebenza okuzinzile kwe-turbine ye-steam kungaqinisekiswa, futhi izindlela ezifika ngesikhathi zingathathwa ukugwema ukulahleka kwezomnotho okungadingekile. Lokhu okulandelayo kuzokwethula lezi zinkomba zokuqapha ezibalulekile nokubaluleka kwazo ngokuningiliziwe.

Ngesikhathi sokusebenza kweTurbine Steam Turbine, TheIndandatho ye-Steam Seal, Njengengxenye ye-High-Pressure Shift Shift Seal, ihlobene ngokuqondile nokusebenza kahle okusebenzayo kanye nokuphepha kweTurbine Turbine. Ngakho-ke, kubalulekile ukuqapha futhi uhlaziye imininingwane elandelayo ngesikhathi sangempela:

Okokuqala, ukuqapha izinga lokushisa. Imvelo esebenzayo ye-Steam Seal Ring inokhahlo kakhulu, futhi imvamisa isesimweni sokushisa okuphezulu nokujikeleza okusheshayo. Uma indandatho ye-seal ishibilika, ingadala ukonakala noma ukulimala kokuqukethwe, ngaleyo ndlela kuthinte ukusebenza kokubekwa uphawu. Ngakho-ke, ngokufaka inzwa yokushisa ukuqapha amazinga okushisa eduze kwendandatho ye-Steam seal ngesikhathi sangempela, ngaleyo ndlela kutholwe opharetha ukuthi athathe ukulimala kwendandatho ye-wal okubangelwa yindandatho eyeqile okubangelwa yindandatho eyeqile okubangelwa yindandatho ngokweqile.

Okwesibili, ukuhlaziya okudlidliza. I-turbine ye-steam izokhiqiza ukunyakaza okuthile ngesikhathi sokusebenza, futhi ukugqoka noma ukulimala kwendandatho yeSteam Seal kuvame ukuholela ezinguquko emaphethini wokudlidliza. Ngokufaka imishini yokuqapha ukudlidliza, lezi zinguquko ezicashile zingabanjwa futhi izinkinga ezingaba khona zingakhonjwa ngokuhlaziywa kwedatha. Isibonelo, uma ukwanda kokudlidliza ngemvamisa ethile kutholwa, kungahle kudalwe ukwanda kwegebe phakathi kwendandatho ye-sal kanye ne-rotor noma ukuxhumana kabi. Kulokhu, inkinga ingaxazululeka ngokulungisa igebe le-seal noma ukufaka esikhundleni se-seal elonakalisiwe.

Ngaphezu kwalokho, ukuqapha ingcindezi. Eminye yemisebenzi esemqoka yendandatho ye-Steam Seal ukuvikela ukuvuza komusi. Isimo sokusebenza sendandatho ye-sal singahlulelwa ngokubheka izinguquko zokucindezela esikhathini esingamasilinda aphezulu. Uma ingcindezi emaphethelweni angaphambili we-cylinder yengcindezi ephezulu yehla ngokungajwayelekile, kungasho ukuthi kunenkinga yokuvuza ngendandatho yesivalo. Ngasikhathi sinye, ingcindezi ye-Steam engena ebhokisini elinemvume ingabhekwa futhi, ngoba uma kunenkinga ngendandatho ye-seal, ukuvuza ngokweqile kwebhokisi kungadala ukuthi kube nokwenziwa kwamafutha okugcotshwa kwamafutha.

Ngaphezu kwalokho, ukuqapha ukugeleza. Ngokuqapha ukugeleza komusi ngendandatho ye-Steam Seal, isimo sokusebenza sendandatho yesivalo singahlulelwa ngokungaqondile. Ngaphansi kwezimo ezijwayelekile, ukugeleza komoya ngendandatho yeselula kufanele kube ezinzile. Uma izinga lokugeleza likhula ngokuzumayo, lingakhombisa ukuthi ukusebenza kokubekwa uphawu kwendandatho ye-sal kwehle, futhi okunye ukuhlola kuyadingeka ngomonakalo noma ezinye izinkinga.

Ngaphezu kwalokho, ukuqapha okuzwakalayo. Yize kungeyona enembile njengezindlela ezingenhla, ezinye izinkinga ezingaba khona zingatholakala ngokuqapha umsindo. Isibonelo, imisindo engajwayelekile noma imisindo ingakhombisa ukuthi kukhona ukuxhumana okungajwayelekile phakathi kwendandatho ye-samba kanye ne-rotor, noma iringi ye-seal ngokwayo igqokwa noma ilimele. Kusetshenziswa ubuchwepheshe obuphambili bokuqapha be-acoustic ukuqapha, lezi zinkinga zingakhonjwa ekuqaleni ukugwema ukwehluleka okukhulu.

Ngokuhlanganisa izindlela ezingenhla, isimo sokusebenza se-Steam Seal Ring singabhekwa ngempumelelo, izinkinga ezingaba khona zingatholakala futhi ziphathwe ngendlela efike ngesikhathi, futhi ukusebenza okuzinzile kweTurbine ye-Steam kungaqinisekiswa. Inganciphisa kakhulu izindleko zokusebenza futhi yandise impilo yensiza yemishini, okuyisilinganiso esibalulekile sokuqinisekisa ukusebenza kwesikhathi kwesikhathi eside kweTurbine Turbine.
