安装草莓视频app黄:离心风机后如何调试：

①试运行时，仔细(xi)(xi)阅读产品说明书，检查接线(xian)方(fang)法(fa)是否(fou)(fou)与(yu)接线(xian)图(tu)一致，仔细(xi)(xi)检查供电(dian)(dian)(dian)(dian)风机电(dian)(dian)(dian)(dian)源(yuan)的工作电(dian)(dian)(dian)(dian)压(ya)是否(fou)(fou)符合(he)要(yao)求，电(dian)(dian)(dian)(dian)源(yuan)是否(fou)(fou)不同或相(xiang)同，配电(dian)(dian)(dian)(dian)部件的容量是否(fou)(fou)符合(he)要(yao)求。

②鼓(gu)风机允许全(quan)(quan)压(ya)(ya)(ya)启动(dong)(dong)(dong)或降压(ya)(ya)(ya)电动(dong)(dong)(dong)，但(dan)应注(zhu)意额定电流在(zai)全(quan)(quan)压(ya)(ya)(ya)启动(dong)(dong)(dong)时(shi)(shi)约(yue)为5-7倍。降压(ya)(ya)(ya)启动(dong)(dong)(dong)扭矩与电压(ya)(ya)(ya)平方成正比，电网容量不足时(shi)(shi)应采用降压(ya)(ya)(ya)启动(dong)(dong)(dong)。

③试运行(xing)时(shi)，首(shou)先启动低速(su)，检查旋转方向是(shi)否正确，启动高速(su)时(shi)，风机静止后启动，避(bi)免(mian)高速(su)反转，开关跳闸，电机损坏。

④试运行时，人数超过2人，1人控制电源，1人观察鼓风机的运行情况，发现异常现象立即停止检查。首先，检查旋转方向是否正确。离心鼓风机开(kai)始运(yun)行后，检查(cha)各相运(yun)行电(dian)流(liu)是(shi)否平(ping)衡(heng)，电(dian)流(liu)是(shi)否超过额定电(dian)流(liu)运(yun)行5分钟(zhong)后，停止检查(cha)鼓风机是(shi)否有异常现象(xiang)，确认无异常后再启动运(yun)行。

⑤对于离心风机和风机(ji)(ji)箱，当进气口完(wan)全打开时，需要大(da)(da)量的(de)电(dian)(dian)(dian)力。如果进气口完(wan)全打开，电(dian)(dian)(dian)机(ji)(ji)有损坏的(de)危险。鼓风机(ji)(ji)试运行时，尽(jin)量关(guan)闭鼓风机(ji)(ji)的(de)入口和出口管道(dao)的(de)阀门，运行后逐渐(jian)打开阀门，直至达(da)到必要条件，注意(yi)鼓风机(ji)(ji)的(de)运行电(dian)(dian)(dian)流是否大(da)(da)于额定(ding)电(dian)(dian)(dian)流。

⑥当离(li)(li)心风(feng)机(ji)达到正常速度时，应(ying)测量风(feng)机(ji)的输入电(dian)(dian)流(liu)(liu)是否(fou)正常，离(li)(li)心风(feng)机(ji)的运(yun)行电(dian)(dian)流(liu)(liu)不得超过(guo)额(e)定(ding)(ding)电(dian)(dian)流(liu)(liu)。当运(yun)行电(dian)(dian)流(liu)(liu)大(da)于(yu)额(e)定(ding)(ding)电(dian)(dian)流(liu)(liu)时，请(qing)检(jian)查(cha)提(ti)供的电(dian)(dian)压(ya)是否(fou)正常。
