Cov kev siv tseem ceeb ntawm anemometers
Lub anemometer yog ib qho cuab yeej uas ntsuas qhov ntws ntawm huab cua. Nws muaj ntau hom, nrog cua khob anemometers feem ntau siv nyob rau hauv cov chaw nres tsheb huab cua;
Nws muaj peb lub khob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khawm Lub concave nto ntawm lub khob khoob tag nrho lub ntsej muag nyob rau hauv tib txoj kev.
Tag nrho qhov kev nkag siab yog ntsia rau ntawm txoj kab ntsug rotating, thiab nyob rau hauv qhov kev txiav txim ntawm cua, lub khob cua rotates nyob ib ncig ntawm lub axis ntawm ib tug ceev proportional rau cua ceev.
Lwm hom rotary anemometer yog lub tshuab raj hom anemometer, uas muaj peb lub ntsej muag lossis plaub lub ntsej muag propeller ua ib qho khoom siv induction;
Nruab nws nyob rau pem hauv ntej kawg ntawm ib tug cua vane kom nws ib txwm ua raws li cov kev taw qhia ntawm cua. Cov hniav tig ib ncig ntawm kab rov tav axis ntawm qhov nrawm proportional rau cua ceev.
Anemometers tau siv dav thiab tuaj yeem siv tau yooj yim hauv txhua qhov chaw, dav siv hauv kev lag luam xws li lub zog, steel, petrochemical, thiab kev txuag hluav taws xob;
Muaj lwm yam kev siv hauv Beijing Olympics, xws li kev sib tw caij nkoj, kev sib tw rowing, thiab kev sib tw tua, uas txhua tus yuav tsum tau siv cov anemometers rau kev ntsuas.
Cov anemometers tam sim no yog qhov siab heev, uas tuaj yeem ntsuas tsis tau tsuas yog cua ceev, tab sis kuj ntsuas cua kub thiab huab cua ntim.
Muaj ntau qhov kev lag luam uas yuav tsum tau siv cov anemometers, thiab cov kev lag luam pom zoo kom siv xws li kev nuv ntses offshore, ntau yam kiv cua tsim, kev lag luam uas yuav tsum tau siv lub tshuab tso pa tawm, thiab lwm yam.
Lub hom phiaj tseem ceeb ntawm anemometer yog:
1. Ntsuas qhov ceev thiab kev taw qhia ntawm qhov nruab nrab ntws.
2. Ntsuas lub pulsation tshaj tawm ntawm cov khoom ntws thiab nws cov spectrum.
3. Ntsuas qhov Reynolds kev ntxhov siab nyob rau hauv turbulence thiab lub nrawm thiab lub sij hawm sib raug zoo ntawm ob lub ntsiab lus.
4. Ntsuas cov phab ntsa shear stress (feem ntau yog siv cov zaj duab xis kub sojntsuam tso dej yaug nrog phab ntsa, zoo ib yam li lub hauv paus ntsiab lus ntawm kev ntsuas kab nrawm).
5. Ntsuas cov kua dej kub (los ntawm kev ntsuas qhov hloov pauv ntawm qhov kev sojntsuam tsis zoo nrog cov kua dej ua ntej, thiab tom qab ntawd txiav txim siab qhov ntsuas kub raws li qhov ntsuas qhov ntsuas qhov ntsuas).
