Le khasiSteam Turbine Emergency Trip SystemIngabe idivaysi yakhelwe ngokukhethekile ukunciphisa ngokushesha uphethiloli noma ukunikezwa komoya ku-turbine uma kwenzeka kunesimo esiphuthumayo, ukuze kuvikeleke i-turbine, imishini ezungezile kanye nokuphepha kwabasebenzi. Lapho i-turbine ye-Steam Turbine ihlangabezana nezimo ezibucayi njengokushisa ngokweqile, izinga lokushisa eliphakeme, ingcindezi kawoyela ephansi, njll., Kungadlala indima ebalulekile.

Ingxenye ebalulekile yohlelo lwezimo eziphuthumayo yilonaIValve Yezimo Eziphuthumayo. Ngokulawula i-valve ukuvala, umjikelezo wokuvala wasebenza ngokuzenzakalela, kanye nama-inolet ama-valves asemqoka kanye nama-valves alawulayo) avalwa ngokushesha. Lapho nje i-Volenoid valve ephuthumayo ibangelwa, opharetha kumele bahlole ngokushesha futhi bayilungise ukuthola imbangela yenkinga futhi bathathe izinyathelo ezifanele zokuxazulula inkinga.

Ukutholwa kwamaphutha abucayi kuma-turbines athululayo kungenziwa ngezindlela ezimbili: Mechanical and Electrical. Ngokuya ngohlobo lohambo, kukhona nezindlela ezahlukahlukene zokuhamba ama-valve. I-Yoyik yethula ikakhulukazi izinhlobo ezimbili ezisetshenziswa kakhulu: ama-valves aqondiswa uhambo kanye nama-electromagnets avaliwe.

I-Mechan Trip Isolation Valve F3DG5S2-062A-220AC-50DFZK-VB-08

Le khasiI-Mechan Trip Isolation Valve F3DG5S2-062A-220AC-50DFZK-VB-08iyi-valve ye-solenoid decreal ikakhulukazi esetshenziswa kakhulu ezinhlelweni eziphuthumayo ze-hydraulic eziphuthumayo. Lolu hlelo lungumshini we-mechanic overperpeed amaphutha. Lapho ijubane le-turbine ye-steam lingaphezulu kwama-3300r / min, indandatho indiza ngaphansi kwesenzo se-Centrifugal Force, okwenza ukuthi uhambo oluphuthumayo lube luhambo. Idivaysi yohambo oluphuthumayo ishayela i-valve ye-valve e-Trip Valve Valve Group ukuze ibuyise futhi ususe uwoyela wokuphepha wengcindezi ephezulu. Ngemuva kokuthi kukhishwe uwoyela wokuphepha wengcindezelo ephezulu, kuzokhululwa i-valve yendlela eyodwa enomkhawulo we-Overppeed Security Security, ebangela ukucindezelwa kwamafutha ezindaweni zokulayisha i-inlet valdwaulic servodor ye-tubirve turbine ukuze inyama turbine. Ngakho-ke, uwoyela ongaphezulu futhi ophansi we-Steam Valve Hydraulic Actuator Piston uxhumeke echwebeni lokukhipha uwoyela ngokusebenzisa i-valve yayo yokulayisha evulekile, ngaleyo ndlela uvale ngokushesha i-valve ngayinye. Ngemuva kokuthi i-valve ye-main steam ivaliwe ngokuphelele, kuzonikezwa isibonakaliso sokushintshana komkhawulo, futhi i-valve ngayinye yesheke izovalwa ngokujikeleza kukagesi nokulawula.

Ama-Magnetic Trip Ithuluzi 3YV

Ngokungafani nohlobo lwe-Mechanical Trip Valve, idivaysi ye-Magnetic Trip 3YV isetshenziselwa izinhlelo zohambo oluphuthumayo kagesi. Isebenzisa izindlela zikagesi ukuthola amaphutha ahlukahlukene we-turbine turbine, kanye namaphutha afana ne-generator ekhipha kanye namafutha amakhulu kaphethiloli, bese kusebenza kanyekanye kusebenza uhambo lukagesi ku-Mechanical Trip Solenoid (3YV). Nika amandla i-Iron ye-3YV Electromagnetic ye-3YV bese wenza kusebenze indlela yokuvala ukuhambisa idivaysi yohambo oluphuthumayo. Yize isiginali ngemuva kokuthi i-valve ye-main steam ivaliwe ngokuphelele ingadala ukuthi i-valve yokuhlola ukuvala, amasiginali wohambo ahlukahlukene azosebenza ngokuqondile ku-valve ngayinye ye-solenoid ngenkathi enza ama-solenoid valve ashiwo, abenze bavale ngokushesha.

Yize lezi zinhlobo ezimbili zama-valves zinemigomo ehlukene yokusebenza, ukubaluleka kwazo ekusebenzeni okuphephile kwama-turbines e-steam kubalulekile ngokulinganayo. I-Yoyik ihlinzeka ngezimo eziphuthumayo valves F3DG5S2-062A-22062A-2203-50DFZK-VB-08 kanye ne-3yv ngokuqinile ngokuhambisana nezidingo zobuchwepheshe ze-Steam Turbic unit, okuyisinqumo esithembekile sabasebenzisi bamandla.
