雙曲面(mian)攪拌機能有效地(di)消除攪拌死角(jiao)
雙曲(qu)面攪拌(ban)機工作原理
雙(shuang)曲(qu)(qu)面(mian)(mian)(mian)(mian)(mian)攪拌機(ji)曲(qu)(qu)面(mian)(mian)(mian)(mian)(mian)葉(xie)輪(lun)體上表面(mian)(mian)(mian)(mian)(mian)為雙(shuang)曲(qu)(qu)線(xian)(xian)母線(xian)(xian)繞葉(xie)輪(lun)體軸線(xian)(xian)旋(xuan)(xuan)轉(zhuan)形成的(de)(de)(de)(de)雙(shuang)曲(qu)(qu)面(mian)(mian)(mian)(mian)(mian)結構,其(qi)*的(de)(de)(de)(de)葉(xie)輪(lun)結構設計,zui大限(xian)度(du)地(di)將流(liu)(liu)體特(te)性與機(ji)械運(yun)(yun)動(dong)相結合。雙(shuang)曲(qu)(qu)線(xian)(xian)的(de)(de)(de)(de)方(fang)(fang)程為xy=b曲(qu)(qu)線(xian)(xian)沿(yan)y軸旋(xuan)(xuan)轉(zhuan)而(er)構成的(de)(de)(de)(de)曲(qu)(qu)面(mian)(mian)(mian)(mian)(mian)體;為了迎合水(shui)(shui)(shui)體流(liu)(liu)動(dong),設計從葉(xie)輪(lun)的(de)(de)(de)(de)中心進(jin)水(shui)(shui)(shui),這一(yi)方(fang)(fang)面(mian)(mian)(mian)(mian)(mian)減少了進(jin)水(shui)(shui)(shui)紊流(liu)(liu),另一(yi)方(fang)(fang)面(mian)(mian)(mian)(mian)(mian)保證了液(ye)(ye)體對葉(xie)輪(lun)表面(mian)(mian)(mian)(mian)(mian)的(de)(de)(de)(de)壓力(li)(li)均勻(yun),從而(er)保證整機(ji)在(zai)運(yun)(yun)動(dong)狀態下(xia)的(de)(de)(de)(de)平衡。在(zai)漸開雙(shuang)弧面(mian)(mian)(mian)(mian)(mian)上均布有八條(tiao)導流(liu)(liu)葉(xie)片,借助液(ye)(ye)體自重(zhong)壓力(li)(li)作(zuo)補充進(jin)水(shui)(shui)(shui)獲得的(de)(de)(de)(de)勢能與葉(xie)輪(lun)旋(xuan)(xuan)轉(zhuan)時產(chan)生(sheng)的(de)(de)(de)(de)離心力(li)(li)形成動(dong)能,液(ye)(ye)體在(zai)重(zhong)力(li)(li)加速(su)度(du)的(de)(de)(de)(de)作(zuo)用下(xia)經(jing)雙(shuang)曲(qu)(qu)面(mian)(mian)(mian)(mian)(mian)結構過渡沿(yan)葉(xie)輪(lun)圓周方(fang)(fang)向(xiang)作(zuo)切線(xian)(xian)運(yun)(yun)動(dong),在(zai)池壁的(de)(de)(de)(de)反射作(zuo)用下(xia),形成自上而(er)下(xia)地(di)循環水(shui)(shui)(shui)流(liu)(liu),故可獲得在(zai)軸向(xiang)(y)和徑向(xiang)(x)方(fang)(fang)向(xiang)的(de)(de)(de)(de)交(jiao)叉水(shui)(shui)(shui)流(liu)(liu)(如雙(shuang)曲(qu)(qu)面(mian)(mian)(mian)(mian)(mian)流(liu)(liu)態圖)。
正是由于G/QSJ型系列雙曲(qu)面(mian)(mian)攪拌機葉輪的(de)結構特性和接近池底安裝的(de)特點,其工(gong)作位置決定了它(ta)對懸(xuan)浮物的(de)防(fang)沉降作用(yong)是直接的(de),在(zai)工(gong)作中(zhong)可獲得理想的(de)攪拌效(xiao)果,能有效(xiao)地消除攪拌死角。較大(da)的(de)比表(biao)面(mian)(mian)積可獲得大(da)面(mian)(mian)積的(de)水(shui)體交(jiao)換。
