鑒(jian)于軸(zhou)流(liu)(liu)風(feng)機有(you)紊流(liu)(liu)區的(de)(de)(de)性能(neng)特(te)點，在(zai)(zai)選型(xing)和使(shi)用時，需要(yao)注意(yi)以(yi)下兩(liang)點：建議(yi)使(shi)用在(zai)(zai)空曠(kuang)(kuang)環境中,軸(zhou)流(liu)(liu)風(feng)機的(de)(de)(de)輸入(ru)功率隨(sui)系統靜壓(ya)的(de)(de)(de)增(zeng)大(da)而增(zeng)大(da)，而在(zai)(zai)紊流(liu)(liu)區，輸入(ru)功率的(de)(de)(de)增(zeng)大(da)幅度會(hui)更大(da)。因此，軸(zhou)流(liu)(liu)風(feng)機一般多(duo)應用在(zai)(zai)有(you)較大(da)空曠(kuang)(kuang)環境的(de)(de)(de)場(chang)合下，可以(yi)使(shi)其工作在(zai)(zai)靜壓(ya)較低(di)(di)的(de)(de)(de)環境下，降低(di)(di)功耗，保(bao)證穩(wen)定性和壽命。定期(qi)清理(li)風(feng)道(dao)(dao),當(dang)軸(zhou)流(liu)(liu)風(feng)機應用在(zai)(zai)較為(wei)封閉的(de)(de)(de)風(feng)道(dao)(dao)系統中時，長期(qi)運(yun)行(xing)后(hou)風(feng)道(dao)(dao)中的(de)(de)(de)積灰(hui)、垃圾(ji)逐漸(jian)(jian)變多(duo)，會(hui)使(shi)風(feng)道(dao)(dao)內的(de)(de)(de)靜壓(ya)逐漸(jian)(jian)增(zeng)加，使(shi)得風(feng)機的(de)(de)(de)運(yun)行(xing)工況點逐漸(jian)(jian)左移。這(zhe)不僅會(hui)降低(di)(di)風(feng)機性能(neng)，更重要(yao)的(de)(de)(de)是(shi)會(hui)增(zeng)加軸(zhou)流(liu)(liu)風(feng)機進入(ru)紊流(liu)(liu)區的(de)(de)(de)風(feng)險。因此必須(xu)要(yao)定期(qi)清理(li)風(feng)道(dao)(dao)，保(bao)證風(feng)機工況點不產生較大(da)偏(pian)移。

1. 技術背(bei)景(jing),在(zai)焊(han)(han)接(jie)接(jie)頭(tou)中(zhong)由(you)于焊(han)(han)接(jie)所引(yin)起的(de)(de)各(ge)種(zhong)裂(lie)(lie)紋，統稱焊(han)(han)接(jie)裂(lie)(lie)紋。焊(han)(han)接(jie)裂(lie)(lie)紋在(zai)焊(han)(han)縫(feng)金屬與熱(re)影響區中(zhong)都(dou)可能產(chan)(chan)(chan)生(sheng)(sheng)，是焊(han)(han)接(jie)凝固冶(ye)金和(he)固相冶(ye)金過程中(zhong)產(chan)(chan)(chan)生(sheng)(sheng)為(wei)危(wei)險的(de)(de)一(yi)種(zhong)缺陷。焊(han)(han)接(jie)結(jie)構產(chan)(chan)(chan)生(sheng)(sheng)的(de)(de)破壞事故大部(bu)分都(dou)是焊(han)(han)接(jie)裂(lie)(lie)紋所引(yin)起的(de)(de)。隨著現(xian)代工業的(de)(de)發展(zhan)，焊(han)(han)接(jie)結(jie)構也趨向大型化、大容量和(he)高(gao)參(can)數發展(zhan)。有的(de)(de)在(zai)低溫(wen)、腐蝕介質下(xia)工作(zuo)，也有的(de)(de)在(zai)高(gao)溫(wen)高(gao)壓下(xia)工作(zuo)，廣(guang)泛都(dou)用到各(ge)種(zhong)高(gao)合金鋼(gang)、不銹鋼(gang)，以(yi)及種(zhong)種(zhong)合金材料。這些材料往往都(dou)對裂(lie)(lie)紋十分敏感，而裂(lie)(lie)紋卻(que)又是大多(duo)重(zhong)大事故的(de)(de)誘(you)因，必須十分重(zhong)視。焊(han)(han)接(jie)裂(lie)(lie)紋種(zhong)類繁多(duo)，產(chan)(chan)(chan)生(sheng)(sheng)的(de)(de)條(tiao)件和(he)原因各(ge)不相同(tong)。有些裂(lie)(lie)紋在(zai)焊(han)(han)后(hou)立即產(chan)(chan)(chan)生(sheng)(sheng)了，有些在(zai)焊(han)(han)后(hou)延續(xu)一(yi)定(ding)(ding)時間再(zai)(zai)產(chan)(chan)(chan)生(sheng)(sheng)，甚(shen)至在(zai)使用過程中(zhong)，在(zai)一(yi)定(ding)(ding)的(de)(de)外界條(tiao)件誘(you)發下(xia)再(zai)(zai)產(chan)(chan)(chan)生(sheng)(sheng)。裂(lie)(lie)紋既出現(xian)在(zai)焊(han)(han)縫(feng)和(he)熱(re)影響區表面，也產(chan)(chan)(chan)生(sheng)(sheng)在(zai)其內部(bu)。它對焊(han)(han)接(jie)結(jie)構的(de)(de)危(wei)害有以(yi)下(xia)幾點(dian)。
