Xaiv cov lus qhia ceev koj tsuas yog muab txoj kab uas hla ntawm lub impeller los ntawm pi (3.14159) uas muab rau koj qhov ncig ntawm lub impeller ntawm sab nraud. Tom qab ntawd koj muab faib los ntawm kev sib hloov ceev ntawm lub impeller (feem ntau rpm, lossis rps) thiab qhov tshwm sim no yog qhov ceev ceev.
txhais li cas los ntawm kev nrawm?
: qhov nrawm ntawm ntug sab nraud ntawm lub log lossis lub taub hau.
Koj ua li cas xam qhov nrawm ntawm RPM?
Koj cov lus qhia meej nrawm tuaj yeem txiav txim siab los ntawm kev siv cov kab zauv hauv qab no: FPM=RPM x. 262 x Hniav Dia (inch).
Nyob ceev ntawm agitator yog dab tsi?
Tip Speed / Peripheral Speed
Blade Speed (ntsis nrawm), ntsuas deb npaum li cas ntawm ib qho taw tes ntawm ntug sab nrauv feem ntau ntawm cov hniav tawg mus rau lub sijhawm teem sijhawm.
compressor ntsis ceev yog dab tsi?
Ib txoj cai dav dav ntawm tus ntiv tes xoo yog tias impeller tip ceev yuav tsum ib txwm muaj nruab nrab ntawm 650 thiab 900 ft / sec (198 thiab 274 m / sec)rau kev tsim cov impeller tag nrho. Impeller tip ceev muaj feem xyuam rau ob qho tib si txhua yam thiab aerodynamic txwv cuam tshuam nrog compressor tsim.
