負壓羅茨真空泵-氣力輸送行業輸送物料-廠家定做
在水(shui)(shui)泥廠中(zhong)，使用zui多的(de)(de)設備(bei)是輸(shu)送設備(bei)，其中(zhong)水(shui)(shui)平(ping)輸(shu)送設備(bei)占60%以上。輸(shu)送粉狀物料zui常見的(de)(de)水(shui)(shui)平(ping)輸(shu)送設備(bei)有螺旋輸(shu)送機、FU鏈板輸(shu)送機、風力輸(shu)送斜槽(cao)等。為了提高大(da)家對水(shui)(shui)平(ping)輸(shu)送設備(bei)的(de)(de)認識和選擇，大(da)宇機械(xie)將三種設備(bei)的(de)(de)特點進行了比較如下：
(1)螺旋輸送機
螺旋氣力輸送機具(ju)有應用廣泛的(de)優點。可輸(shu)送(song)原料、水泥、煤粉(fen)等，可水平輸(shu)送(song)或20°以(yi)內傾斜輸(shu)送(song)；可輸(shu)送(song)干(gan)粉(fen)狀物料和粘(zhan)性濕物料。材料。但其(qi)阻力大(da)(da)、耗電量大(da)(da)、易損件多、維(wei)修工作量大(da)(da)、安裝精度高、密封(feng)困難。
(2)FU鏈(lian)式輸送(song)機(ji)
FU鏈板輸(shu)(shu)送(song)(song)(song)機噪音低(di)，能耗低(di)，運行過程中無粉(fen)體污染。此外，它不需(xu)要像螺旋輸(shu)(shu)送(song)(song)(song)機那樣每隔2~3m放一個(ge)油(you)杯，因此維護保(bao)養(yang)非常方便，近年來(lai)得到廣(guang)泛應用(yong)。特別適用(yong)于輸(shu)(shu)送(song)(song)(song)距離長、磨損大的場合。地(di)面螺旋輸(shu)(shu)送(song)(song)(song)機輸(shu)(shu)送(song)(song)(song)距離超過30m時，輸(shu)(shu)送(song)(song)(song)軸長，不易同心。往(wang)往(wang)需(xu)要兩(liang)端傳(chuan)輸(shu)(shu)，功耗比較(jiao)大。雖然FU鏈板輸(shu)(shu)送(song)(song)(song)機替代蝶(die)形回轉輸(shu)(shu)送(song)(song)(song)機有很多優點，但實踐證明(ming)FU鏈板輸(shu)(shu)送(song)(song)(song)機的維護成本并不低(di)。
(3)空(kong)氣輸送斜(xie)槽
空氣(qi)輸(shu)送(song)(song)斜槽(cao)是(shi)利用(yong)空氣(qi)使(shi)固體顆粒在流(liu)化狀態下(xia)流(liu)動(dong)的(de)輸(shu)送(song)(song)設備。屬于密相流(liu)化輸(shu)送(song)(song)。與螺(luo)旋輸(shu)送(song)(song)機和FU鏈板輸(shu)送(song)(song)機相比，它(ta)具有以(yi)(yi)下(xia)優點(dian)：結(jie)構簡(jian)單，維(wei)修方(fang)便，無活(huo)動(dong)部件(jian)，磨損小(xiao)，經久耐用(yong)；滌綸布(bu)(bu)為(wei)透(tou)氣(qi)層，使(shi)用(yong)壽命長；密封性*、無噪音(yin)、輸(shu)送(song)(song)量大；可(ke)改變輸(shu)送(song)(song)方(fang)向(xiang)，方(fang)便多點(dian)進料(liao)(liao)、多點(dian)卸料(liao)(liao)；動(dong)力消耗小(xiao)，運行安(an)*可(ke)靠(kao)等優點(dian)。缺(que)點(dian)是(shi)不(bu)能輸(shu)送(song)(song)塊狀粘濕(shi)物料(liao)(liao)，不(bu)能向(xiang)上輸(shu)送(song)(song)。只能以(yi)(yi)一定的(de)向(xiang)下(xia)坡度運輸(shu)。一般(ban)運輸(shu)距離(li)不(bu)超過100m。輸(shu)送(song)(song)距離(li)大時，落差(cha)大，給工藝布(bu)(bu)置和土建設計帶來困(kun)難。另外，為(wei)了排(pai)(pai)氣(qi)，還需在風槽(cao)末端加裝(zhuang)(zhuang)簡(jian)易排(pai)(pai)氣(qi)裝(zhuang)(zhuang)置，如采用(yong)單臺除塵器或簡(jian)易布(bu)(bu)袋排(pai)(pai)氣(qi)。
