鑒(jian)于(yu)軸(zhou)流(liu)風(feng)(feng)機(ji)(ji)有(you)紊(wen)流(liu)區的(de)性能特(te)點(dian)(dian)，在選型(xing)和使(shi)用(yong)(yong)時，需要注意以下(xia)兩點(dian)(dian)：建議(yi)使(shi)用(yong)(yong)在空(kong)曠環境中(zhong),軸(zhou)流(liu)風(feng)(feng)機(ji)(ji)的(de)輸(shu)入功率隨系統靜壓(ya)的(de)增大(da)而(er)增大(da)，而(er)在紊(wen)流(liu)區，輸(shu)入功率的(de)增大(da)幅度會更(geng)大(da)。因(yin)此，軸(zhou)流(liu)風(feng)(feng)機(ji)(ji)一般多(duo)應(ying)用(yong)(yong)在有(you)較(jiao)大(da)空(kong)曠環境的(de)場(chang)合下(xia)，可以使(shi)其(qi)工作在靜壓(ya)較(jiao)低(di)的(de)環境下(xia)，降低(di)功耗，保證穩定性和壽命。定期(qi)清理風(feng)(feng)道,當軸(zhou)流(liu)風(feng)(feng)機(ji)(ji)應(ying)用(yong)(yong)在較(jiao)為封閉的(de)風(feng)(feng)道系統中(zhong)時，長期(qi)運(yun)行(xing)后風(feng)(feng)道中(zhong)的(de)積(ji)灰(hui)、垃圾逐(zhu)漸(jian)變多(duo)，會使(shi)風(feng)(feng)道內的(de)靜壓(ya)逐(zhu)漸(jian)增加(jia)，使(shi)得風(feng)(feng)機(ji)(ji)的(de)運(yun)行(xing)工況(kuang)點(dian)(dian)逐(zhu)漸(jian)左移。這不(bu)僅會降低(di)風(feng)(feng)機(ji)(ji)性能，更(geng)重要的(de)是會增加(jia)軸(zhou)流(liu)風(feng)(feng)機(ji)(ji)進入紊(wen)流(liu)區的(de)風(feng)(feng)險(xian)。因(yin)此必須要定期(qi)清理風(feng)(feng)道，保證風(feng)(feng)機(ji)(ji)工況(kuang)點(dian)(dian)不(bu)產生較(jiao)大(da)偏(pian)移。

1、在設計靜壓箱時，如果按著規定的風速成進行設計，箱體將會很大；一般的靜壓箱長邊要寬出風管邊400mm，高度要寬出風管高度400mm ；2、選靜壓箱的經驗是5~10db(a)/m，推薦防火閥阻抗復合型（似乎空調通風系統一般都用這個）消聲器10~15db(a)/m；3、控制風速 在2.5以內 若體積太大可適當得提高一下風速 關于長度一般大于1米沒有其他得強制要求 ；4、高度×深度=靜壓箱截面面積，靜壓箱截面面積×2.5m/s=風機風量，至于高度和深度怎么配，自己把握吧；5、用你機組的風量L÷3米/秒，可得到你靜壓箱一個面的面積，然后你根據你房子的高度，假如是4米，可你的機組是2米高，在減去軟接頭大概0.5米，上面留高0.5米，那你的靜壓箱只有1米高，那你就可以確定寬度了，有了兩個數，第三個數也就容易確定了，這里主要的是要看自己的空調機房夠不夠位置，如果防火閥夠位(wei)置就盡(jin)量(liang)的(de)(de)(de)大點(dian)！！長(chang)度(du)的(de)(de)(de)計(ji)算方法(fa)也是一樣的(de)(de)(de)，你(ni)知(zhi)道了寬度(du)，那么你(ni)的(de)(de)(de)寬度(du)乘(cheng)以(yi)長(chang)度(du)不也是有個面(mian)積嗎(ma)？這個面(mian)積也要等于L/3，不過在設(she)計(ji)院(yuan)里的(de)(de)(de)面(mian)風速(su)是取用2m/s的(de)(de)(de)，如(ru)果夠空間，就做大點(dian)吧(ba)；

在(zai)葉輪(lun)(lun)(lun)運(yun)(yun)轉初期(qi)及所(suo)有(you)(you)(you)定(ding)期(qi)檢查的(de)時候，只(zhi)要(yao)一有(you)(you)(you)機會，都必(bi)(bi)(bi)須檢查葉輪(lun)(lun)(lun)是否出現(xian)裂紋、磨損、積塵(chen)等缺(que)陷。只(zhi)要(yao)有(you)(you)(you)可(ke)(ke)能，都必(bi)(bi)(bi)須使葉輪(lun)(lun)(lun)保持清(qing)潔狀態，并定(ding)期(qi)用鋼絲刷刷去上面的(de)積塵(chen)和銹(xiu)皮(pi)等，因為隨(sui)著運(yun)(yun)行時間的(de)加長，這些灰塵(chen)由(you)于不(bu)可(ke)(ke)能均勻地附著在(zai)葉輪(lun)(lun)(lun)上，而造成葉輪(lun)(lun)(lun)平(ping)衡破(po)壞，以(yi)至引起(qi)轉子振(zhen)動(dong)(dong)(dong)。葉輪(lun)(lun)(lun)只(zhi)要(yao)進(jin)行了(le)修理(li)，就需要(yao)對其再作動(dong)(dong)(dong)平(ping)衡。如有(you)(you)(you)條件(jian)，可(ke)(ke)以(yi)使用便(bian)攜試動(dong)(dong)(dong)平(ping)衡儀在(zai)現(xian)場進(jin)行平(ping)衡。在(zai)作動(dong)(dong)(dong)平(ping)衡之前，必(bi)(bi)(bi)須檢查所(suo)有(you)(you)(you)緊定(ding)螺栓是否上緊。因為葉輪(lun)(lun)(lun)已經(jing)在(zai)不(bu)平(ping)衡狀態下運(yun)(yun)行了(le)一段時間，這些螺栓可(ke)(ke)能已經(jing)松動(dong)(dong)(dong)。
