离心风机是一种驱动流体机械，依靠输入机械能来提高气体压力和输送气体。离心风机广泛用于工厂、矿山、隧道、冷却塔、车辆、船舶和建筑物的通风、除尘和冷却。锅炉和工业炉的通风和引风机；空调设备和家用电器中的冷却和通风；烘干选粮；风洞中的风源、气垫船的充气和推进等。使用注意事项:关机程序1.紧急停车:机组调试过程中，出现下列情况之一时，应立即进行紧急停车。急停的操作是按下主电机的停止按钮，然后处理停止后的善后工作。a、离心风机突然强烈振动，并已超过跳闸值。b、机体内部有划痕或异常摩擦声。c、任何轴承或密封冒烟现象，或轴承温度急剧上升到报警值。d、油压低于报警值，无法恢复正常。e、油箱液位低，存在吸空现象。f、轴向位移值不断增大，达到报警值。2.正常停机:机组正常停机应按以下程序进行。a、逐渐打开排气阀(或出口旁通阀)，并逐渐关闭排气阀。b、逐渐调低进气节流阀至20~25。c、按下停机按钮，并注意停机过程中有无异常现象。d、机组停机5~10分钟后，或轴承温度降至45℃以下时，可停止供油。对于带有浮动环密封的装置，密封油泵必须继续供油，直到阀体温度低于80℃。机组停机后，转子应在2~4小时内定期旋转180度。安装很重要1.整个离心风机装置的安装应直接放在基础上，并用成对的斜垫找平。2.对于现场组装的离心风机，底座上的切割面应得到适当保护，不得生锈或操作。底座放在基础上时，要用成对的斜垫找平。3.轴承座与(yu)(yu)底(di)座(zuo)应(ying)(ying)连接(jie)紧密，纵(zong)向(xiang)不(bu)(bu)(bu)(bu)(bu)平度不(bu)(bu)(bu)(bu)(bu)应(ying)(ying)超(chao)过0.2/1000。用水平仪在主(zhu)轴(zhou)(zhou)(zhou)上(shang)测(ce)量(liang)时(shi)(shi)(shi)(shi)(shi)，水平不(bu)(bu)(bu)(bu)(bu)平度不(bu)(bu)(bu)(bu)(bu)应(ying)(ying)超(chao)过0.3/1000。4.磨刮(gua)轴(zhou)(zhou)(zhou)瓦(wa)前，应(ying)(ying)校正(zheng)(zheng)转(zhuan)子轴(zhou)(zhou)(zhou)线(xian)(xian)和(he)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)壳(qiao)(qiao)轴(zhou)(zhou)(zhou)线(xian)(xian)，同(tong)时(shi)(shi)(shi)(shi)(shi)调(diao)(diao)整叶轮(lun)与(yu)(yu)进气(qi)(qi)口(kou)的(de)(de)(de)(de)(de)(de)间隙(xi)(xi)和(he)主(zhu)轴(zhou)(zhou)(zhou)与(yu)(yu)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)壳(qiao)(qiao)后侧板轴(zhou)(zhou)(zhou)孔的(de)(de)(de)(de)(de)(de)间隙(xi)(xi)，以(yi)(yi)(yi)符(fu)(fu)合(he)设备技术(shu)文(wen)件(jian)(jian)的(de)(de)(de)(de)(de)(de)规定(ding)。5.主(zhu)轴(zhou)(zhou)(zhou)和(he)轴(zhou)(zhou)(zhou)瓦(wa)组(zu)装(zhuang)(zhuang)时(shi)(shi)(shi)(shi)(shi)，应(ying)(ying)按设备技术(shu)文(wen)件(jian)(jian)的(de)(de)(de)(de)(de)(de)规定(ding)进行(xing)(xing)(xing)(xing)检(jian)(jian)(jian)查(cha)(cha)(cha)。轴(zhou)(zhou)(zhou)承(cheng)盖与(yu)(yu)轴(zhou)(zhou)(zhou)瓦(wa)的(de)(de)(de)(de)(de)(de)过盈量(liang)应(ying)(ying)为(wei)(wei)(wei)0.03~0.04mm(测(ce)量(liang)轴(zhou)(zhou)(zhou)瓦(wa)外(wai)径和(he)轴(zhou)(zhou)(zhou)承(cheng)座(zuo)内(nei)径)。6.组(zu)装(zhuang)(zhuang)风(feng)(feng)(feng)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)壳(qiao)(qiao)时(shi)(shi)(shi)(shi)(shi)，机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)壳(qiao)(qiao)的(de)(de)(de)(de)(de)(de)位(wei)(wei)置应(ying)(ying)以(yi)(yi)(yi)转(zhuan)子的(de)(de)(de)(de)(de)(de)轴(zhou)(zhou)(zhou)线(xian)(xian)为(wei)(wei)(wei)准(zhun)，叶轮(lun)进气(qi)(qi)口(kou)与(yu)(yu)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)壳(qiao)(qiao)进气(qi)(qi)口(kou)之间的(de)(de)(de)(de)(de)(de)轴(zhou)(zhou)(zhou)向(xiang)和(he)径向(xiang)间隙(xi)(xi)应(ying)(ying)加(jia)速(su)到设备技术(shu)文(wen)件(jian)(jian)规定(ding)的(de)(de)(de)(de)(de)(de)范(fan)围内(nei)。同(tong)时(shi)(shi)(shi)(shi)(shi)，检(jian)(jian)(jian)查(cha)(cha)(cha)地脚螺栓是否(fou)(fou)(fou)(fou)紧固(gu)。如(ru)(ru)果(guo)设备技术(shu)文(wen)件(jian)(jian)中没(mei)有(you)规定(ding)间隙(xi)(xi)值(zhi)，轴(zhou)(zhou)(zhou)向(xiang)间隙(xi)(xi)一(yi)般应(ying)(ying)为(wei)(wei)(wei)叶轮(lun)外(wai)径的(de)(de)(de)(de)(de)(de)1/100，径向(xiang)间隙(xi)(xi)应(ying)(ying)均匀分布，其(qi)值(zhi)应(ying)(ying)为(wei)(wei)(wei)叶轮(lun)外(wai)径的(de)(de)(de)(de)(de)(de)1.5/1000~3/1000(以(yi)(yi)(yi)较小者为(wei)(wei)(wei)准(zhun))。调(diao)(diao)整时(shi)(shi)(shi)(shi)(shi)尽(jin)量(liang)减小间隙(xi)(xi)值(zhi)，提高风(feng)(feng)(feng)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)效率。7.风(feng)(feng)(feng)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)对中时(shi)(shi)(shi)(shi)(shi)，风(feng)(feng)(feng)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)轴(zhou)(zhou)(zhou)与(yu)(yu)电(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)轴(zhou)(zhou)(zhou)的(de)(de)(de)(de)(de)(de)不(bu)(bu)(bu)(bu)(bu)对中:径向(xiang)定(ding)位(wei)(wei)运(yun)(yun)动(dong)(dong)不(bu)(bu)(bu)(bu)(bu)应(ying)(ying)超(chao)过0.05mm，倾斜度不(bu)(bu)(bu)(bu)(bu)应(ying)(ying)超(chao)过0.2/1000。8.对于装(zhuang)(zhuang)有(you)滚(gun)动(dong)(dong)轴(zhou)(zhou)(zhou)承(cheng)的(de)(de)(de)(de)(de)(de)离(li)(li)(li)心(xin)(xin)风(feng)(feng)(feng)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)，转(zhuan)子安装(zhuang)(zhuang)后，两(liang)个轴(zhou)(zhou)(zhou)承(cheng)架上(shang)的(de)(de)(de)(de)(de)(de)轴(zhou)(zhou)(zhou)承(cheng)孔的(de)(de)(de)(de)(de)(de)错位(wei)(wei)会(hui)(hui)发生灵活转(zhuan)动(dong)(dong)。调(diao)(diao)试(shi)方(fang)(fang)法离(li)(li)(li)心(xin)(xin)风(feng)(feng)(feng)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)是一(yi)种复杂(za)的(de)(de)(de)(de)(de)(de)设备，主(zhu)要(yao)由(you)进气(qi)(qi)口(kou)、气(qi)(qi)阀(fa)、叶轮(lun)、电(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)和(he)出(chu)气(qi)(qi)口(kou)组(zu)成。在不(bu)(bu)(bu)(bu)(bu)同(tong)的(de)(de)(de)(de)(de)(de)条(tiao)(tiao)件(jian)(jian)下(xia)(xia)，离(li)(li)(li)心(xin)(xin)风(feng)(feng)(feng)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)(de)(de)(de)效果(guo)是不(bu)(bu)(bu)(bu)(bu)同(tong)的(de)(de)(de)(de)(de)(de)。因此(ci)，不(bu)(bu)(bu)(bu)(bu)同(tong)部件(jian)(jian)的(de)(de)(de)(de)(de)(de)运(yun)(yun)行(xing)(xing)(xing)(xing)条(tiao)(tiao)件(jian)(jian)不(bu)(bu)(bu)(bu)(bu)一(yi)致(zhi)(zhi)，会(hui)(hui)影响离(li)(li)(li)心(xin)(xin)风(feng)(feng)(feng)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)(de)(de)(de)效果(guo)。离(li)(li)(li)心(xin)(xin)风(feng)(feng)(feng)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)(ji)调(diao)(diao)试(shi)到良好状态可(ke)以(yi)(yi)(yi)从多方(fan
