9907-164 Woodward 505 Digital Governor New

I-Woodward 9907-164 505 I-Digital Governor yama-Steam Turbines ane-Actuator eyodwa noma e-split-Range

Incazelo evamile
I-505E iyisilawuli esisekelwe ku-32-bit microprocessor esidizayinelwe ukulawula ukukhishwa okukodwa, ukukhipha/ukungenisa, noma ukungenisa izinjini zesitimu. I-505E iyahleleka ensimini, ivumela umklamo owodwa ukuthi usetshenziselwe izinhlelo eziningi zokulawula ezahlukene kanye nokunciphisa izindleko nesikhathi sokuhola. Isebenzisa isofthiwe eqhutshwa yimenyu ukuze iqondise unjiniyela wensimu ekuhleleni isilawuli kujeneretha ethile noma uhlelo lokusebenza lwedrayivu eyimishini. I-505E ingalungiselelwa ukuthi isebenze njengeyunithi ezimele noma ingasetshenziswa ngokuhambisana nesistimu yokulawula esabalalisiwe yeplanti.

I-505E iyinkambu elungisekayo yokulawula i-steam turbine kanye nephaneli yokulawula u-opharetha (OCP) kuphakheji eyodwa. I-505E inephaneli yokulawula ye-opharetha ebanzi kuphaneli yangaphambili ehlanganisa isibonisi semigqa emibili (izinhlamvu ezingu-24 ngomugqa ngamunye) kanye nesethi yokhiye abangu-30. Le OCP isetshenziselwa ukulungisa i-505E, ukwenza izinguquko zohlelo lwe-inthanethi, nokusebenzisa i-turbine/system. Isibonisi semigqa emibili ye-OCP sinikeza imiyalelo eqondakala kalula ngesiNgisi, futhi u-opharetha angakwazi ukubuka amanani wangempela kanye nephoyinti lokusetha esikrinini esifanayo.

I-505E ihlangana namavalvu okulawula amabili (i-HP ne-LP) ukuze ilawule amapharamitha amabili futhi ikhawulele ipharamitha eyodwa eyengeziwe uma kudingeka. Amapharamitha amabili alawulwayo ngokuvamile isivinini (noma umthwalo) kanye nokucindezela kokudonsa / ukungena (noma ukugeleza), nokho, i-505E ingasetshenziswa ukulawula noma ukukhawulela: ingcindezi yokungena kwe-turbine noma ukugeleza, ukukhipha (ingcindezi yangemuva) ingcindezi noma ukugeleza, isigaba sokuqala. ingcindezi, amandla ejeneretha aphumayo, indawo yokungena esitshalweni kanye/noma amazinga wokuphuma, i-compressor inlet noma i-exhaust pressure noma ukugeleza, imvamisa yeyunithi/yesitshalo, izinga lokushisa lenqubo, nanoma iyiphi enye ipharamitha yenqubo ehlobene ne-turbine.

I-505E ingaxhumana ngokuqondile nesistimu yokulawula esakazwa yisitshalo kanye/noma iphaneli yokulawula opharetha esekelwe ku-CRT ngezimbobo ezimbili zokuxhumana ze-Modbus. Lawa machweba asekela ukuxhumana kwe-RS-232, RS-422, noma RS-485 kusetshenziswa i-ASCII noma i-RTU MODBUS yokudlulisa izivumelwano. Ukuxhumana phakathi kwe-505E nesitshalo i-DCS nakho kungenziwa ngoxhumo oluqinile. Ngoba wonke ama-setpoints we-505E PID angalawulwa ngezimpawu zokufaka ze-analog, ukulungiswa kwesixhumi esibonakalayo nokulawula akwenziwa umhlatshelo.

I-505E iphinde inikeze izici ezilandelayo: Inkomba yohambo lokuphuma lokuqala (ingqikithi yohambo olu-5), ukugwema isivinini esibalulekile (amabhendi esivinini ama-2), ukulandelana kokuqala okuzenzakalelayo (isiqalo esishisayo nesibandayo), isivinini esimbaxambili/amandla omthwalo, ukutholwa kwejubane elinguziro, ukuphakama inkomba yesivinini yohambo lwesivinini esikhulu, nokwabelana ngomthwalo okuvumelanisa phakathi kwamayunithi.
