Koj puas paub tias yam twg yog tus yuam sij rau kev lag luam thiab kev ua haujlwm ntawm anemometer?
Anemometer, raws li lub npe qhia, yog ib qho cuab yeej rau ntsuas huab cua tshaj tawm. Nws muaj ntau hom, thiab anemometer yog ib qho anemometer. Lub rotating khob anemometer yog thawj zaug tsim los ntawm Robinson hauv tebchaws Askiv. Thaum ntawd, muaj plaub lub khob, ces peb khob tau siv xwb. Peb lub khob parabolic lossis hemispherical 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 khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Peb-khob anemometer feem ntau yog siv 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. Lub concave nto ntawm lub khob khoob yog tag nrho nyob rau hauv ib qho kev taw qhia. Tag nrho cov induction ib feem yog ntsia rau ntawm ntsug rotating ncej, thiab nyob rau hauv qhov kev txiav txim ntawm cua quab yuam, lub khob cua rotates nyob ib ncig ntawm lub ncej ntawm ib tug ceev proportional rau cua ceev. Lwm lub anemometer rotary yog lub kiv cua anemometer, uas muaj peb-hniav los yog plaub-hluav taws propeller raws li qhov kev xav, uas yog ntsia rau pem hauv ntej kawg ntawm lub 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.
Cov teb ntawm kev siv cov anemometers
Anemometers tau siv dav thiab tuaj yeem siv tau yooj yim hauv txhua qhov chaw. Anemometers tuaj yeem siv dav hauv hluav taws xob, hlau, petrochemical, txuag hluav taws xob thiab lwm yam lag luam. Muaj lwm daim ntawv thov hauv Beijing Olympic Games, kev sib tw caij nkoj, kev sib tw rowing, teb Anemometers yog xav tau rau kev sib tw tua thiab lwm yam. Lub anemometer tam sim no yog qhov siab heev, ntxiv rau kev ntsuas cua nrawm, nws tuaj yeem ntsuas cua kub thiab cua ntim. Muaj ntau qhov kev lag luam uas yuav tsum tau siv cov anemometers, kev lag luam pom zoo: kev lag luam nuv ntses, ntau yam kev lag luam kiv cua, kev lag luam uas yuav tsum tau muaj cua tshuab thiab tso pa tawm, thiab lwm yam.
A. Kev ntsuas huab cua thiab cua ceev yuav tsum tau ua ua ntej. Tag nrho cov teebmeem purification tau txais raws li qhov tsim ntawm huab cua ntim thiab cua ceev.
B. Ua ntej kuaj, xyuas seb lub kiv cua puas ua haujlwm li qub. Qhov loj ntawm lub qhov hluav taws xob thiab cov pa cua yuav tsum tau ntsuas ntawm qhov chaw.
C. Rau ib qho unidirectional flow (laminar flow) chav huv si, cov huab cua ntim yog txiav txim siab los ntawm cov khoom ntawm qhov nruab nrab cua ceev ntawm chav tsev thiab cov khoom ntawm qhov chaw huv.
(Nyob rau ntu {{0}}.3m deb ntawm lub lim perpendicular mus rau airflow raws li qhov piv txwv, thiab teem tsis pub tsawg tshaj 5 xeem cov ntsiab lus ntawm seem raws li qhov ntsuas qhov sib nrug yuav tsum tsis txhob ntau tshaj. 0.6m, thiab tus lej lej ntawm txhua qhov kev nyeem tau raug coj los ua qhov nruab nrab cua ceev.) Vertical ib leeg Qhov ntsuas ntawm qhov kev taw qhia ntws (laminar flow) chav huv huv yog nyob ntawm kab rov tav ntawm {{8} }.8m ~ 1m hauv av; qhov ntsuas ntawm kab rov tav unidirectional ntws (laminar flow) chav huv yog nyob ntawm qhov ntsug ntawm cov khoom siv cua ntawm 0.5m ~ 1m; Tus naj npawb ntawm cov ntsiab lus xeem yuav tsum tsis pub tsawg tshaj 10, thiab qhov kev ncua deb ntawm lawv yuav tsum tsis txhob siab tshaj 2m, thiab lawv yuav tsum tau muab sib npaug.
D. Rau lub tuyere nruab nrog lub lim, cov huab cua ntim yog txiav txim los ntawm cov khoom ntawm qhov nruab nrab cua ceev ntawm tuyere seem thiab net cross-sectional cheeb tsam ntawm tuyere. (Qhov nruab nrab cua ceev tau txais los ntawm tsis pub tsawg tshaj 6 qhov sib npaug ntawm cov ntsiab lus ntsuas ntawm ntu ntawm tuyere lossis ntu xa mus rau qhov chaw pabcuam huab cua.)
E. Thaum muaj cov kav dej ntev ntev ntawm lub qhov cua ntawm lub tuyere thiab lub qhov tau los yog tuaj yeem drilled, cov cua ntim tuaj yeem txiav txim siab los ntawm txoj kev cua duct. (Txoj qhov tsis pub tsawg dua 3 npaug ntawm cov yeeb nkab txoj kab uas hla lossis 3 npaug ntawm qhov ntev ntawm sab loj ua ntej lub qhov hluav taws xob cua;)
F. Rau cov kab hluav taws xob sib npaug, faib cov ntsuas ntsuas mus rau ntau qhov sib npaug me me, txhua ntu me me yog nyob ze rau ib square li sai tau, sab ntev tsis ntau tshaj 200mm, qhov ntsuas qhov ntsuas yog nyob rau hauv nruab nrab ntawm qhov me me. , tab sis tag nrho cov seem yuav tsum tsis pub tsawg tshaj 3 qhov kev xeem Rau lub voj voog cua ducts, cov seem ntsuas yuav tsum tau muab faib thiab cov naj npawb ntawm cov ntsiab lus xeem yuav tsum tau muab faib raws li qhov sib npaug ntawm cheeb tsam; Cov qhov yuav tsum tau qhib rau ntawm phab ntsa sab nrauv ntawm cov pa cua, thiab cov thermal anemometer probes lossis pitot hlab yuav tsum tau muab tso rau. (Hloov mus rau huab cua ntim los ntawm kev ntsuas dynamic siab.)
