氧化鋁粉輸送料封泵-水泥粉氣力輸送機
粉體氣力輸送機料(liao)封(feng)(feng)泵利用(yong)高速氣(qi)流(liu)(liu)的(de)(de)噴射作用(yong)輸(shu)送(song)(song)粉(fen)狀物料(liao)，在等效距(ju)離(li)450m、高度40m范圍內使(shi)用(yong)效果較(jiao)*。料(liao)封(feng)(feng)泵（氣(qi)力輸(shu)送(song)(song)系(xi)(xi)統）是氣(qi)動壓差原理(li)、射流(liu)(liu)技術和流(liu)(liu)化(hua)技術的(de)(de)結合，充(chong)分吸(xi)收了現代氣(qi)力輸(shu)送(song)(song)兩相流(liu)(liu)理(li)論。經過(guo)多年的(de)(de)運行實踐(jian)，是針對粉(fen)體氣(qi)力輸(shu)送(song)(song)過(guo)程(cheng)中大量中短距(ju)離(li)連續輸(shu)送(song)(song)的(de)(de)特點而開發的(de)(de)專用(yong)設(she)備。用(yong)于火電廠、水泥、冶金(jin)、化(hua)工(gong)、碼(ma)頭等系(xi)(xi)統的(de)(de)除(chu)灰(hui)系(xi)(xi)統及其他行業的(de)(de)氣(qi)力輸(shu)送(song)(song)設(she)備。
氣力輸送機料(liao)(liao)封泵(beng)是(shi)(shi)利用氣(qi)(qi)(qi)流(liu)(liu)(liu)(liu)沿管道輸(shu)送(song)散(san)(san)裝物料(liao)(liao)的(de)設備。其(qi)工作(zuo)原理是(shi)(shi)來自(zi)氣(qi)(qi)(qi)源的(de)低(di)壓空(kong)氣(qi)(qi)(qi)經(jing)調節閥、活動氣(qi)(qi)(qi)管、噴嘴進入泵(beng)內(nei)的(de)擴(kuo)散(san)(san)室(shi)。當落料(liao)(liao)斗落入噴嘴和擴(kuo)散(san)(san)器之間(jian)的(de)高(gao)速(su)氣(qi)(qi)(qi)流(liu)(liu)(liu)(liu)區域時(shi)，它被吹走(zou)。除底部(bu)氣(qi)(qi)(qi)化裝置氣(qi)(qi)(qi)化外(wai)，物料(liao)(liao)氣(qi)(qi)(qi)化成懸浮狀態。之后(hou)由高(gao)速(su)氣(qi)(qi)(qi)流(liu)(liu)(liu)(liu)送(song)入擴(kuo)散(san)(san)器的(de)減速(su)器，流(liu)(liu)(liu)(liu)經(jing)喉(hou)部(bu)擴(kuo)散(san)(san)器，進入輸(shu)送(song)管道，被送(song)到所需(xu)的(de)卸(xie)料(liao)(liao)點(dian)（例如：倉內(nei)），完(wan)成給(gei)料(liao)(liao)過程(cheng)。
由于低壓料封泵的(de)工藝系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)簡(jian)單，所配置的(de)控制系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)的(de)邏輯關系(xi)(xi)(xi)(xi)也簡(jian)單。根據系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)配置，即使PLC控制系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)癱瘓，也不會影響系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)的(de)正常(chang)運(yun)行(xing)，操作維(wei)護(hu)仍然簡(jian)單可(ke)靠。該設(she)(she)備區別于其(qi)(qi)他泵的(de)關鍵點在(zai)于它不同于火(huo)電廠、水(shui)泥(ni)、冶金、化工、碼頭、攪拌站系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)等行(xing)業的(de)氣力輸送(song)設(she)(she)備中的(de)其(qi)(qi)他除(chu)灰(hui)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)(tong)。
