Steam Turbine shuff valve hf02-02-01y

Incazelo emfushane:

I-HF02-02-01Y Shut-Off valve isetshenziswa ikakhulukazi njenge-actuator yohlelo lokulawula uwoyela we-EH, olufanele ama-660mw nangaphansi amayunithi. Isetshenziselwa ikakhulukazi ukunquma ngokushesha i-oyela ye-oyela ye-hydraulic serlodor ngesikhathi sokuchitha umthwalo noma izimo zohambo, ukugwema ukwehla kokucindezelwa kowoyela wesistimu ngenxa yokuphuza okusheshayo kwe-hydraulic. Uhlobo lokulawula i-actuator, owaziwa nangokuthi uhlobo lwe-servo, lungalawula i-steam valve kunoma yisiphi isikhundla esiphakathi nendawo futhi ngokulinganayo ukulungisa ivolumu ye-inlet steam ukuze ahlangabezane nezidingo. Ihlanganiswe ngemoto ye-hydraulic, inzwa yokusuka emugqeni, i-valve evulekile, i-valve esheshayo ye-solenoid, i-servo valve, i-valve ye-valve, ingxenye yokuhlunga, njll.

Imininingwane Yomkhiqizo

Le khasiI-Shutff valveHf02-02-01y, ebizwa nangokuthi i-wetful valve, njengoba igama libonisa, i-valve elayisha iphampu ye-hydraulic ngaphansi kwemibandela ethile. I-shutroff valve hf02-02-01y imvamisa i-valve echichimayo enesikhundla ezimbili ngendlela emibili ye-valve (imvamisa aI-Solenoid valve). Umsebenzi wayo ukusetha ingcindezi enkulu yohlelo (iphampu yamafutha) lapho ingalayishi. Lapho umbuso wokulayisha (oguqulwa ngesenzo salezi zikhundla ezimbili zendlela emibili ye-valve), uwoyela wokucindezela ubuyela ngqo ethangini lamafutha, kanyeiphampu yamafuthaIngcindezi yehle ku-zero ukufeza ukulawulwa okuthile kwesifunda, thuthukisa impilo yepompo kawoyela, futhi unciphise ukusetshenziswa kwamandla. Kungokwesifunda esihlanganisiwe esifundeni. I-shutroff valve hf02-02-01y, eyaziwa nangokuthi ingcindezi yokunciphisa i-valve, isetshenziselwa ukulungisa ingcindezi edingekayo ku-actuator. Ixhumeke ochungechungeni esifundeni futhi ngokuvamile akuguquki.

Sebenza

I-HF02-02-01Y Shuloff Valve ikakhulukazi inemisebenzi elandelayo kuhlelo lwe-turbine Ehword:

1. Lawula ukuhamba kukawoyela bese ulungisa amapharamitha wokusebenza kohlelo. Ngomqondo noma ukuvula ngokuzenzakalela nokuvala i-shutroff valve, izinga lokugeleza kwamafutha egatsheni ngalinye lohlelo lwe-EH kawoyela lulawulwa, futhi amapharamitha asebenzayo anjengengcindezi yesistimu kanye nengcindezi yokugeleza alungiswa ukuze aqinisekise ukusebenza okuphephile futhi okuzinzile kohlelo.

2. Hlukanisa uhlelo lokulungiswa nokulungisa. Ngokuvala i-shutroff valve, ingxenye ethile noma imishini yomuntu ngamunye yohlelo lwe-EH kawoyela ingahlukaniswa ukuze kulungiswe, okunye esikhundleni, kanye neminye imisebenzi ngaphandle kokuthinta ukusebenza okujwayelekile kohlelo.

3. Vikela izingozi futhi uvikele ukuphepha kwemishini. Uma kwenzeka kuqhuma kwamapayipi noma ezinye izingozi ezingalindelekile ohlelweni lwamafutha e-EH, ukuvala okufika ngesikhathi i-shutroff valve inganqamula ukugeleza kwamafutha, ukuvikela izingozi ukuthi zingandisi, futhi zivikele ukuphepha kwemishini yohlelo.

I-4. Ukulawulwa kokuphambukiswa kokwenza kahle ukusebenza kohlelo. Ngokubeka ukuvulwa kwama-valves ahlukene ashubile, kungenzeka ukufeza ukulawulwa kokugeleza okuhlukanisayo kokugeleza kwamafutha ohlelweni lwe-EH, uthuthukise ukuhanjiswa kohlelo, futhi uthuthukise ukusebenza kohlelo.

5. Sebenzisa ukulawula kwe-cascade kohlelo. Ama-valves ama-roff amaningi afakiwe ohlelweni lwe-EH OL ukuze afinyelele khona ukulawulwa kwe-Cascade kohlelo, ngaleyo ndlela ngokulawula isimo esisebenzayo sohlelo nokuhlangabezana nezidingo zezimo ezisebenzayo zokusebenza.
