鑒于(yu)軸(zhou)(zhou)流風(feng)機(ji)(ji)(ji)有(you)紊流區(qu)的(de)(de)(de)性(xing)(xing)能(neng)特點，在(zai)(zai)選型和(he)使用(yong)時(shi)，需要(yao)注意(yi)以(yi)下兩點：建議使用(yong)在(zai)(zai)空曠(kuang)環境中(zhong),軸(zhou)(zhou)流風(feng)機(ji)(ji)(ji)的(de)(de)(de)輸(shu)入(ru)功率隨系統(tong)靜(jing)(jing)壓的(de)(de)(de)增大(da)(da)而增大(da)(da)，而在(zai)(zai)紊流區(qu)，輸(shu)入(ru)功率的(de)(de)(de)增大(da)(da)幅度會更(geng)大(da)(da)。因此(ci)，軸(zhou)(zhou)流風(feng)機(ji)(ji)(ji)一般多應用(yong)在(zai)(zai)有(you)較大(da)(da)空曠(kuang)環境的(de)(de)(de)場合下，可以(yi)使其工作在(zai)(zai)靜(jing)(jing)壓較低(di)(di)(di)的(de)(de)(de)環境下，降低(di)(di)(di)功耗，保證穩定(ding)性(xing)(xing)和(he)壽命(ming)。定(ding)期清(qing)理(li)(li)風(feng)道(dao)(dao)(dao),當軸(zhou)(zhou)流風(feng)機(ji)(ji)(ji)應用(yong)在(zai)(zai)較為(wei)封(feng)閉的(de)(de)(de)風(feng)道(dao)(dao)(dao)系統(tong)中(zhong)時(shi)，長期運(yun)(yun)行(xing)后(hou)風(feng)道(dao)(dao)(dao)中(zhong)的(de)(de)(de)積灰、垃圾逐漸(jian)(jian)變多，會使風(feng)道(dao)(dao)(dao)內(nei)的(de)(de)(de)靜(jing)(jing)壓逐漸(jian)(jian)增加，使得風(feng)機(ji)(ji)(ji)的(de)(de)(de)運(yun)(yun)行(xing)工況(kuang)點逐漸(jian)(jian)左移。這不僅會降低(di)(di)(di)風(feng)機(ji)(ji)(ji)性(xing)(xing)能(neng)，更(geng)重(zhong)要(yao)的(de)(de)(de)是會增加軸(zhou)(zhou)流風(feng)機(ji)(ji)(ji)進入(ru)紊流區(qu)的(de)(de)(de)風(feng)險。因此(ci)必須要(yao)定(ding)期清(qing)理(li)(li)風(feng)道(dao)(dao)(dao)，保證風(feng)機(ji)(ji)(ji)工況(kuang)點不產(chan)生較大(da)(da)偏移。
