Huringa Rankine mīhini huri hiko mamaoa

Ahakoa hangarau te ahunga whakamua, ko te tino nohopuku, ka taea e maha e kite koe i te āhuatanga i reira whakamahia te mau parau tumu i roto i ngā tipu hou i kitea i roto i te rau tau whakamutunga. Hei tauira, he huringa Rankine, i whakaaro i roto i te rau tau 19, whakamahia te i roto i te kapohau steam me inaianei.

Te ma'imi nui

i kitea huringa Rankine i ahupūngao Kotimana me te mataaro pūkaha e noho a mahi i roto i te rautau tekau mā iwa. Kua ingoa te tenenga kua i roto i te kororia o te pūtaiao nui, ko wai i hoki he tahi-kaiwhakarewa o thermodynamics hangarau.

whanau William John Rankin i roto i 1820 i roto i Edinburgh, i reira ako ai ia i te Institute mō ngā tau e toru. Heoi, ki te whakaoti tenei wahi e kore te kaipūtaiao taea no te mea o te āhuatanga pūtea uaua. Otiia kihai i tenei ārai ahupūngao aravihi whakatinana i te maha o ngā āhuatanga whai hua. Na, i roto i te 1849 riro ia te whārite o thermodynamics, e whakaahua te hononga i waenganui i te pūngao pūkaha me te wera. I mauria ano e i roto i te hanga o te ariā mamaoa-engine, ka whakawhanakehia te mau parau tumu i hanga e te pūtake o te mahi o tenei kōwae. Enei tikanga kėia te tukanga, i i homai te ingoa i roto i te kororia o te kaiputaiao - huringa Rankine.

Highlights

Tenei huringa o mahi ko te faaiteraa ariā o te tukanga thermodynamic tango wahi i roto i te otaota steam mana i roto i te aratau tāruarua. Ka taea e tatou te wehe taua ngā mahi taketake ngā i roto i tenei huringa:

• evaporates te wai i te pēhanga teitei;
• Kei te whakawhänui rāpoi wai i roto i te āhua haurehu waihā;
• condenses korohū maku i runga i te taiepa o te oko;
• pēhanga inu te nui haere (hoki ki te uara tuatahi).

Kia kï hoki, e te tōtika waiariki o tenei huringa ko tika hautanga ki te pāmahana tuatahi. Ano, meinga te tōtika o tenei tukanga e pēhanga me te āhua ngāwhā o te tohu i runga i te tūranga tohutoro me te putanga.

mīhini huri hiko mamaoa

Tenei kōwae Ko te pūkaha wera, kia rite ki te hua o nei hangaia mana hiko te. Ka taea te māngai nga wāhanga matua o tenei tāutanga i roto i te rārangi e whai ake:

• wahi turanga, e ngā o te taua rotor me matatahi piri;
• he mema pahoho he wae pērā i pupuha me stator.

Ka taea te āhuatanga mahi tāuta i tenei ara. whangai te wai i roto i te āhua haurehu waihā i tiketike pāmahana me te pēhanga e ki te pupuha mīhini huri hiko. Here, i tere paorangi He panoni pūngao moe ki rua nekeneke, ai te rua o te matūriki aia. Tenei, i roto i te tahuri, hanga he awa hau e mahi i runga i te uruuru. Huringa o enei āhuatanga ai te rotor ki te neke, reira whakaputa hiko. tōtā atu o korohū, a mutu ai te reira i roto i te kaiwhiwhi wai mātao motuhake i te wai mau ake ano ki te exchanger wera. Ko te kupu, i reira te mea he tukurua o ngā mahi, kawea e te roto i huringa Rankine.

whakamahia tēnei parau tumu i roto i ngā pūnaha i roto i ngā tipu te mana karihi, kia rite ki te whakamahia te reira i roto i ngā waeine mīhini huri hiko tu-anake mō te mana whakatupuranga. Tenei kaupapa Ko e tawhiti te tōtika tino me economical. Plants whakahaere i runga i te mau parau tumu o Rankine, tohaina puta noa i te ao.
