粉體氣力輸送機一般根據物(wu)料搬運系統(tong)的要求，物(wu)料裝卸(xie)地(di)點的各種條件，有關的生產工藝過程和物(wu)料的特性(xing)等來確定(ding)各主要參數。

　　1、輸(shu)(shu)送(song)能(neng)力：輸(shu)(shu)送(song)機械的輸(shu)(shu)送(song)能(neng)力是指(zhi)單位時(shi)(shi)間(jian)內輸(shu)(shu)送(song)的物料(liao)量。在輸(shu)(shu)送(song)散狀物料(liao)時(shi)(shi)，以每小時(shi)(shi)輸(shu)(shu)送(song)物料(liao)的質量或(huo)體積計算(suan)；在輸(shu)(shu)送(song)成件(jian)物品時(shi)(shi)，以每小時(shi)(shi)輸(shu)(shu)送(song)的件(jian)數計算(suan)。

　　2、輸(shu)送(song)(song)速度：提(ti)高(gao)輸(shu)送(song)(song)速度可(ke)以提(ti)高(gao)輸(shu)送(song)(song)能力。在以輸(shu)送(song)(song)帶作牽引(yin)(yin)件且輸(shu)送(song)(song)長度較(jiao)大(da)(da)時，輸(shu)送(song)(song)速度日趨增大(da)(da)。但高(gao)速運轉的帶式(shi)輸(shu)送(song)(song)機(ji)需注意振(zhen)動(dong)(dong)、噪聲和啟動(dong)(dong)、制動(dong)(dong)等問題。對于以鏈條(tiao)作為(wei)牽引(yin)(yin)件的輸(shu)送(song)(song)機(ji)，輸(shu)送(song)(song)速度不宜過(guo)大(da)(da)，以防(fang)止增大(da)(da)動(dong)(dong)力載(zai)荷。同時進行工藝(yi)(yi)操(cao)作的輸(shu)送(song)(song)機(ji)，輸(shu)送(song)(song)速度應按生(sheng)產(chan)工藝(yi)(yi)要求確定。

　　3、構件尺寸：氣力輸送機械的構件尺寸(cun)包括(kuo)輸(shu)送(song)帶寬度(du)、板條寬度(du)、料(liao)斗容(rong)積、管(guan)道直(zhi)徑和容(rong)器大小等。這些構件尺寸(cun)都直(zhi)接(jie)影響輸(shu)送(song)機的輸(shu)送(song)能力(li)。

　　4、輸送(song)長(chang)度和傾角：輸送(song)線(xian)路(lu)長(chang)度和傾角大小直接影響輸送(song)機(ji)的總(zong)阻力和所(suo)需要的功率(lv)。
