Rankine voj voog chav turbine

Txawm tias kev siv technology tshiab kev kawm yog heev ceev, koj muaj peev xwm feem ntau pom ib tug teeb meem uas lub hauv paus ntsiab lus uas siv nyob rau hauv niaj hnub nroj tsuag uas twb tshwm sim nyob rau hauv lub xeem caug xyoo. Piv txwv li, ib tug Rankine voj voog, uas twb yees ua nyob rau hauv lub xyoo pua puv 19, yog siv nyob rau hauv lub chav turbines thiab tam sim no.

Qhov zoo inventor

Rankine voj voog twb tshwm sim los ntawm Scottish physicist thiab engineer uas nyob thiab ua hauj lwm nyob rau hauv lub thib kaum cuaj caug xyoo. Tus invention tau muaj npe nyob rau hauv Honor ntawm tus poj tus paub txog, uas kuj yog ib tug co-founder ntawm kev thermodynamics.

Renkin Uilyam Yauhas yug los nyob rau hauv 1820 nyob rau hauv Edinburgh, qhov uas nws kawm nyob rau tom lub koom haum rau peb lub xyoos. Txawm li cas los, kom tiav no qhov chaw tus paub txog yuav tsis vim hais tias ntawm lub nyuaj nyiaj txiag qhov teeb meem no. Tab sis qhov no tsis tiv thaiv tub ntxhais ntse physicist siv ib tug xov tooj uas pab tau discoveries. Yog li ntawd, nyob rau hauv 1849 nws tau txais qhov sib npaug ntawm thermodynamics, uas piav qhia txog txoj kev sib raug ntawm cov neeg kho tshuab zog thiab tshav kub. Tsis tas li ntawd nqa tawm kev tsim kho ntawm lub chav engine kev tshawb xav thiab tsim cov qauv uas tsim lub hauv paus ntawm lub chaw ua hauj lwm ntawm no unit. Cov cai no tshwm sim tawm lub txheej txheem uas tau muab lub npe nyob rau hauv Honor ntawm tus paub txog - Rankine voj voog.

highlights

Qhov no voj voog ntawm lub lag luam yog cov theoretical kev qhia txog lub thermodynamic dab noj qhov chaw thaum lub sij hawm lub chav fais fab nroj tsuag nyob rau hauv repetition hom. Peb yuav paub qhov txawv xws yooj yim ua hauj lwm muaj nyob rau hauv no voj voog:

• cov kua suab ntawm ib tug kub siab;
• Dej lwg me me nyob rau hauv lub gaseous xeev yog expanding;
• ntub chav condenses rau ntawm phab ntsa ntawm cov hlab;
• kua siab yog ntau zog (xa rov qab mus rau thawj lub tus nqi).

Nws kuj yuav raug muab sau tseg tias thermal efficiency ntawm no mus los yog ncaj qha xwm yeem mus rau thawj zaug kub. Tsis tas li ntawd, cov efficiency ntawm tus txheej txheem no yog tshwm sim los ntawm siab thiab thermal lub xeev ntawm cov qhov taw qhia nyob rau hauv reference txoj hauj lwm thiab lub qhov hluav taws xob.

chav turbine

Qhov no unit yog ib tug kub engine, raws li ib tug tshwm sim ntawm uas hluav taws xob hwj chim yog generated. Lub ntsiab Cheebtsam ntawm no installation yuav tsum sawv cev nyob rau hauv cov nram qab no daim ntawv teev:

• rooj noj ib feem, uas muaj ib tug rotor thiab tuaj txuas thereto;
• ib tug ruaj ruaj neeg muaj yam xws li nozzle thiab stator.

installation ua hauj lwm yuav tsum yus nyob rau hauv no txoj kev. Cov dej nyob rau hauv lub gaseous lub xeev thaum muaj kev kub kub thiab siab yog noj mus rau hauv lub turbine nozzle. Ntawm no, nyob supersonic tshaj tawm tej zaum zog transforms rau hauv kinetic khub, nyob rau lub khub ntawm tsav particle. Qhov no, nyob rau hauv lem, tsim ib tug roj kwj uas ua rau lub turbine hniav. Kev sib hloov ntawm cov ntsiab ua rau lub rotor yuav tawm mus, li no ua hluav taws xob. Ntxiv hws ntawm chav, thiab nws settles nyob rau hauv ib tug tshwj xeeb receiver chilled dej los ntawm cov kua catches dua mus rau hauv lub tshav kub exchanger. Yog li, muaj ib tug repetition ntawm kev ua hauj lwm, uas yog nqa tawm Rankine voj voog.

Qhov no txoj ntsiab cai no siv nyob rau hauv tshuab rau hauv nuclear fais fab nroj tsuag, raws li nws yog siv nyob rau hauv stand-alone turbine chav nyob rau hwj chim tiam. Qhov no tswvyim yog nyob deb ntawm cov feem ntau npaum thiab yig. Nroj tsuag kev khiav hauj lwm nyob rau hauv lub hauv paus ntsiab lus ntawm Rankine, faib thoob plaws hauv lub ntiaj teb no.
