鑒于軸流風機有紊流區的性能特點，在選型和使用時，需要注意以下兩點：渝北風機建議使用在空曠環境中,軸流風機的輸入功率隨系統靜壓的增大而增大，而在紊流區，輸入功率的增大幅度會更大。因此，軸流風機一般多應用在有較大空曠環境的場合下，可以使其工作在靜壓較低的環境下，降低功耗，保證穩定性和壽命。風機批發定期(qi)清理(li)(li)風道(dao),當軸流風機(ji)應用在(zai)較為封(feng)閉的(de)(de)(de)風道(dao)系統中時，長期(qi)運行(xing)后風道(dao)中的(de)(de)(de)積灰、垃圾逐漸(jian)變多，會使(shi)風道(dao)內(nei)的(de)(de)(de)靜壓逐漸(jian)增(zeng)加，使(shi)得風機(ji)的(de)(de)(de)運行(xing)工況(kuang)(kuang)點(dian)逐漸(jian)左移。這不(bu)僅會降(jiang)低風機(ji)性能，更重要(yao)的(de)(de)(de)是(shi)會增(zeng)加軸流風機(ji)進(jin)入(ru)紊流區的(de)(de)(de)風險(xian)。因此必須要(yao)定期(qi)清理(li)(li)風道(dao)，保證風機(ji)工況(kuang)(kuang)點(dian)不(bu)產(chan)生較大偏移。
