鑒于軸(zhou)流風(feng)(feng)機(ji)有(you)(you)紊(wen)流區的性能特點(dian)，在(zai)選型和使(shi)(shi)(shi)用(yong)時(shi)，需(xu)要注意以下兩點(dian)：建議使(shi)(shi)(shi)用(yong)在(zai)空(kong)曠環境(jing)中(zhong),軸(zhou)流風(feng)(feng)機(ji)的輸(shu)入(ru)功(gong)率隨系統靜(jing)壓的增大(da)而增大(da)，而在(zai)紊(wen)流區，輸(shu)入(ru)功(gong)率的增大(da)幅度會更(geng)大(da)。因(yin)此(ci)，軸(zhou)流風(feng)(feng)機(ji)一般多(duo)應(ying)用(yong)在(zai)有(you)(you)較大(da)空(kong)曠環境(jing)的場(chang)合下，可以使(shi)(shi)(shi)其工(gong)作在(zai)靜(jing)壓較低的環境(jing)下，降(jiang)(jiang)低功(gong)耗，保(bao)證穩定性和壽命。定期清理風(feng)(feng)道,當軸(zhou)流風(feng)(feng)機(ji)應(ying)用(yong)在(zai)較為封(feng)閉(bi)的風(feng)(feng)道系統中(zhong)時(shi)，長期運行后風(feng)(feng)道中(zhong)的積灰、垃(la)圾逐(zhu)漸(jian)變多(duo)，會使(shi)(shi)(shi)風(feng)(feng)道內的靜(jing)壓逐(zhu)漸(jian)增加(jia)，使(shi)(shi)(shi)得風(feng)(feng)機(ji)的運行工(gong)況點(dian)逐(zhu)漸(jian)左(zuo)移。這不(bu)僅會降(jiang)(jiang)低風(feng)(feng)機(ji)性能，更(geng)重要的是會增加(jia)軸(zhou)流風(feng)(feng)機(ji)進入(ru)紊(wen)流區的風(feng)(feng)險。因(yin)此(ci)必須(xu)要定期清理風(feng)(feng)道，保(bao)證風(feng)(feng)機(ji)工(gong)況點(dian)不(bu)產生較大(da)偏移。
