回(hui)轉式(shi)風機的(de)(de)機器(qi)型號不多，重復的(de)(de)也較少(shao)，因(yin)此選(xuan)擇(ze)型號較為簡單。有以(yi)下(xia)幾點：1、回(hui)轉式(shi)風機型號；2、電機功率；3、風量參(can)數(shu)；4、口徑參(can)數(shu)。

知(zhi)(zhi)道(dao)回轉風(feng)(feng)機(ji)的型(xing)(xing)號(hao)(hao)就可(ke)(ke)以(yi)確(que)(que)定(ding)(ding)(ding)他的價(jia)格，那(nei)么其(qi)他參(can)(can)(can)(can)(can)數(shu)也(ye)就較好確(que)(que)定(ding)(ding)(ding)；如果(guo)沒(mei)有(you)型(xing)(xing)號(hao)(hao)，只有(you)電機(ji)功(gong)率參(can)(can)(can)(can)(can)數(shu)作(zuo)為參(can)(can)(can)(can)(can)考，那(nei)么不能直(zhi)接確(que)(que)定(ding)(ding)(ding)風(feng)(feng)機(ji)型(xing)(xing)號(hao)(hao)，如果(guo)加(jia)上一(yi)個(ge)(ge)風(feng)(feng)量(liang)就可(ke)(ke)以(yi)進行(xing)(xing)型(xing)(xing)號(hao)(hao)選擇了(le)；知(zhi)(zhi)道(dao)風(feng)(feng)量(liang)參(can)(can)(can)(can)(can)數(shu)也(ye)只能進行(xing)(xing)粗(cu)略選型(xing)(xing)，如果(guo)知(zhi)(zhi)道(dao)風(feng)(feng)量(liang)參(can)(can)(can)(can)(can)數(shu)和(he)(he)壓力參(can)(can)(can)(can)(can)數(shu)就可(ke)(ke)以(yi)進行(xing)(xing)精確(que)(que)選型(xing)(xing)；同樣單純知(zhi)(zhi)道(dao)口徑參(can)(can)(can)(can)(can)數(shu)也(ye)是無法確(que)(que)定(ding)(ding)(ding)型(xing)(xing)號(hao)(hao)的，需要確(que)(que)定(ding)(ding)(ding)口徑參(can)(can)(can)(can)(can)數(shu)和(he)(he)風(feng)(feng)量(liang)參(can)(can)(can)(can)(can)數(shu)可(ke)(ke)以(yi)進行(xing)(xing)選型(xing)(xing)。因此，除了(le)單純知(zhi)(zhi)道(dao)回轉風(feng)(feng)機(ji)型(xing)(xing)號(hao)(hao)可(ke)(ke)以(yi)直(zhi)接選擇外，其(qi)他參(can)(can)(can)(can)(can)數(shu)都需要至少兩個(ge)(ge)參(can)(can)(can)(can)(can)數(shu)才可(ke)(ke)以(yi)確(que)(que)定(ding)(ding)(ding)風(feng)(feng)機(ji)型(xing)(xing)號(hao)(hao)進行(xing)(xing)選擇。
