Cov yam ntxwv thiab kev siv tseem ceeb ntawm anemometers
Nta
1. Qhov loj me, me me cuam tshuam rau qhov chaw ntws;
2. Kev siv ntau yam. Nws tuaj yeem siv tsis tau tsuas yog rau cov pa roj xwb tab sis kuj rau cov kua dej, thiab tuaj yeem siv rau hauv subsonic, transonic thiab supersonic flows ntawm gases.
3. Cov lus teb zaus yog siab, mus txog 1 MHz.
4. Siab ntsuas qhov tseeb thiab zoo repeatability. Qhov tsis zoo ntawm qhov kub-xaim anemometer yog tias qhov kev sojntsuam cuam tshuam nrog qhov chaw ntws mus rau qee qhov thiab cov hlau kub yog qhov yooj yim tawg.
5. Ntxiv rau qhov ntsuas qhov nruab nrab ceev, nws tseem tuaj yeem ntsuas qhov ntsuas pulsation thiab qhov ntsuas kub; Ntxiv nrog rau kev ntsuas cov lus tsa suab hauv ib qho kev taw qhia, nws tseem tuaj yeem ntsuas qhov nrawm nrawm hauv ntau cov lus qhia ib txhij.
Lub hom phiaj tseem ceeb
1. Ntsuas qhov ceev thiab kev taw qhia ntawm qhov nruab nrab ntws.
2. Ntsuas lub pulsation tshaj tawm thiab spectrum ntawm cov khoom ntws.
3. Ntsuas qhov kev ntxhov siab ntawm Reynolds nyob rau hauv turbulent flow thiab lub nrawm sib raug zoo thiab lub sij hawm correlation ntawm ob lub ntsiab lus.
4. Ntsuas phab ntsa shear kev ntxhov siab (feem ntau yog ua los ntawm kev siv cov yeeb yaj kiab kub sojntsuam tso dej yaug nrog cov phab ntsa, lub hauv paus ntsiab lus zoo ib yam li kev ntsuas kub xov hluav taws xob).
5. Ntsuas cov kua dej kub ( ntsuas qhov hloov nkhaus ntawm qhov kev sojntsuam tsis kam nrog cov kua dej ua ntej, thiab tom qab ntawd txiav txim siab qhov ntsuas kub raws li qhov ntsuas qhov ntsuas tsis kam.
6 Kev ceev faj rau kev siv Anemometer
1. Lub anemometer yog txwv tsis pub siv nyob rau hauv ib puag ncig ntawm cov pa taws kub hnyiab vim nws yuav ua rau hluav taws kub lossis tawg.
2. Thov nyeem cov lus qhia rau kev siv ua ntej siv thiab siv lub anemometer nruj me ntsis raws li cov lus qhia.
3. Thaum lub sij hawm siv, yog lub anemometer emissions tsis hnov tsw, suab los yog pa luam yeeb, los yog cov kua ntws mus rau hauv lub anemometer, thov tsum txhob siv nws thiab tshem tawm lub roj teeb.
4. Tsis txhob kov qhov sensor hauv qhov kev sojntsuam thaum siv.
5. Tsis txhob siv cov kua dej tsis haum los so lub anemometer.
6. Yog tias tsis siv lub roj teeb ntev, lub roj teeb yuav tsum tau muab tshem tawm thiab khaws cia kom raug. Tsis txhob nias nws hnyav.
