Dab tsi yog qhov tseem ceeb ceev ntawm lub pob zeb

Qhov tseem ceeb ceev (Nc) ntawm lub pob zeb yog qhov kev sib hloov ceev uas lub zog centrifugal ntawm cov xov xwm sib tsoo (pob) hauv lub zeb yog sib npaug rau lub zog ntawm lub ntiajteb txawj nqus ua rau lawv. Ntawm qhov ceev ceev no, cov xov xwm sib tsoo tau tuav tawm tsam sab hauv phab ntsa ntawm lub zeb los ntawm lub zog centrifugal, tiv thaiv lawv los ntawm kev poob dawb thiab ua rau muaj kev cuam tshuam nrog lub plhaub zeb.

Qhov tseem ceeb ceev ntawm lub pob zeb tuaj yeem suav nrog cov qauv hauv qab no:

Qhov twg:

Nc yog qhov tseem ceeb ceev ntawm lub zeb (hauv revolutions ib feeb, rpm).

g yog qhov acceleration vim lub ntiajteb txawj nqus (kwv yees li 9.81 m/s²).

R yog lub vojvoog ntawm lub zeb (hauv meters).

Qhov tseem ceeb ceev ntawm lub pob zeb nyob ntawm nws txoj kab uas hla thiab lub vojvoog ntawm cov xov xwm sib tsoo. Feem ntau, cov pob zeb ua haujlwm ntawm qhov nrawm ntawm 65% mus rau 75% ntawm qhov tseem ceeb ceev rau kev sib tsoo zoo. Tshaj qhov nrawm nrawm tuaj yeem ua rau muaj kev hnav ntau dhau ntawm lub plhaub zeb thiab kev sib tsoo xov xwm, nrog rau kev sib tsoo tsis zoo. Yog li ntawd, kev khiav hauj lwm lub pob zeb ntawm los yog ze nws qhov tseem ceeb ceev yog feem ntau pom zoo rau kev ua tau zoo.
