Tsab chav turbine

Leej twg yog "lub plawv", muab txoj sia rau feem ntau txiv neej-tshuab yog ib tug nrog combustion engine (ICE). Txawm li cas los, nws tsis yog ib txwm.

Los ntawm yav tag los pov

Ua ntej lub era ntawm lub internal combustion engine rau ib ntev lub sij hawm, lub hauv paus ntawm kev siv technology tshiab kev kawm yog ib tug chav turbine. Qhov no yog cov tsis tshua muaj cov ntaub ntawv nyob qhov twg lub invention yog pom tias yuav zoo li ntawd uas tseem yuav tsum siv hnub no, albeit nrog ib tug xov tooj ntawm kev txhim kho. Nws yuav tsum tau muab sau tseg hais tias ua hauj lwm rau ib tug ob peb tias yuav tsum tsis txhob yuav tsis meej pem nrog chav turbines thiab classic tsheb (tib yam tshem ciav hlau). Lawv muaj ib tug txawv ua hauj lwm hauv paus ntsiab lus, thiab cov efficiency yog incomparable.

Chav turbine. invention

Nws yog ntseeg hais tias cov thawj lub sij hawm xws li ib tug turbine tsim thiab siv nyob rau hauv lub hlau Swede P. Laval. Rov qab nyob rau hauv 1889 muaj ib tug xav tau ib tug zoo engine rau cov mis nyuj separator, muaj peev xwm tsim tau txoj kev sib hloov ceev ntawm tsawg kawg yog 100 revolutions ib ob. Lub hauv paus ntsiab lus ntawm cov lag luam ntawm lub turbine yog heev yooj yim: nyob rau hauv ib tug saum npoo tsau mus rau lub tog raj kheej axis ntawm tus hniav muab tso rau hauv uas ntaus lub dav hlau ntawm superheated chav los ntawm sab nraum pem hauv ntej ntawm lub boiler. Tej zaum lub zog ntawm cov khub transformed rau hauv kinetic zog, ua rau cov tog raj kheej tig. Laval empirically txiav txim hais tias qhov zoo tshaj plaws kev tshwm sim yog tau yog hais tias tus khiav ntawm chav yuav khiav los ntawm cov khob hliav qab-zoo li tus nozzle, es ncaj hlab.

Txawm li cas los, ib tug paub chav turbine Englishman C. A. Parsons. Nws tsim nws yog yuav luag thaum uas tig mus nrog Laval, tab sis tsis tau tsuas yog zoo, tab sis kuj guessed kev cob cog rua rau ib tug hluav taws xob generator (qhov chiv keeb ntawm cov niaj hnub system ntawm GD).

Nyob rau hauv 1894, nws tsim lub nkoj, uas tau tsav los ntawm lub engine raws li nyob rau hauv ib tug chav turbine (nyiaj pab ntau tshaj ceev ntawm txog 60 km / h). Lub tswv yim yog zoo li ntawd hais tias tom qab 1900 feem ntau ntawm cov warships tau nruab nrog uas zoo sib xws xyaw.

peb lub sij hawm

Ntawm cov hoob kawm, txij li thaum lub invention thiab cov thawj chav turbine qauv tau tshiab, thiab tsim qauv drawbacks yog tshem tawm. Classical chav turbine system muaj xws li ob lub Cheebtsam: ib taag stator nrog nozzles thiab ib yam rotor unit (lub tog raj kheej) nrog tuaj tsis muaj tsev nyob rau hauv nws cov vaj tse nyob. Nyob ntawm seb cov kev taw qhia ntawm chav tsab ntawv tsa suab txawv ob hom rotor siv - radial thiab axial. Cov yav tas los yog echoes ntawm tus thawj ntsiab: lawv ob peb hais tawm vector perpendicular mus rau lub tog raj kheej axis, thiab cov vanes yog thaum uas tig mus rau nws. Nyob rau hauv lub axial kev taw qhia ntawm tus khub coincides nrog lub axis, thiab kev sib hloov yog generated vim tshwj xeeb orientation ntawm lub nplooj pu.

Ntau npaum siv zog tej zaum ob peb los ncu turbines nrog ob peb thooj voos kheej kheej (multihull). Txawm li cas los, vim rau qhov cumbersome xwm thiab complexity ntawm tus tsim xws ntsiab yog siv qhov twg lawv siv yog kev lag kev luam justified. Thooj Voos Kheej Kheej housings yuav tsum tau nyob rau ib qho axis thiab yuav mechanically ywj siab. Lub system ntawm cov ntsaws ruaj ruaj thiab diaphragms tiv thaiv txawv txav lag luam ntawm lub tag nrho qhov system (lwm huab cua kom tsawg, cov to chav bypassing degrees thiab li ntawd.).

Txoj kev loj hlob ntawm chav turbine technology

Thaum uas tsis muaj ntau ntau cov siab zog thiab tsis tshua muaj hwj chim turbine classical insufficiently zoo. Lawv hloov los ntawm chav ntsia hlau tshuab. Qhov no Lavxias teb sab kev loj hlob yog ib tug natural evolution ntawm tus thawj qauv. Hauv lub vaj tse yog cov txheej txheem ntawm rotors nrog helical lobes. Cov khoom chav nyob rau hauv lub qhov chaw ntawm tus hniav ntawm lub tom ntej no screws, muaj lub turnover thiab ntxiv pub nres. Ntxiv mus, cov kab noj hniav feem ntawm lub chav ua txhab thiab ua hauj lwm nyob rau kev sib hloov ntawm lub ntsia hlau rotor. Qhov no tsim pub rau cov zoo dua kev siv ntawm muab zog chav.
