螺(luo)(luo)旋(xuan)輸(shu)(shu)(shu)送(song)(song)(song)機(ji)(ji)葉片(pian)材(cai)質不(bu)同(tong)性能的材(cai)料對螺(luo)(luo)旋(xuan)輸(shu)(shu)(shu)送(song)(song)(song)機(ji)(ji)的葉片(pian)形狀有不(bu)同(tong)的要求。我們在輸(shu)(shu)(shu)送(song)(song)(song)物料時不(bu)能掉以輕心，螺(luo)(luo)旋(xuan)輸(shu)(shu)(shu)送(song)(song)(song)機(ji)(ji)的速(su)(su)度(du)(du)越(yue)快，伸縮輸(shu)(shu)(shu)送(song)(song)(song)機(ji)(ji)多(duo)少錢，輸(shu)(shu)(shu)送(song)(song)(song)效(xiao)果越(yue)好，但螺(luo)(luo)旋(xuan)輸(shu)(shu)(shu)送(song)(song)(song)機(ji)(ji)的輸(shu)(shu)(shu)送(song)(song)(song)效(xiao)果取決于設(she)備(bei)本身的設(she)計，其速(su)(su)度(du)(du)應(ying)符合標準的臨界速(su)(su)度(du)(du)。當許多(duo)設(she)備(bei)的螺(luo)(luo)桿速(su)(su)度(du)(du)超過臨界速(su)(su)度(du)(du)時，物料將在輸(shu)(shu)(shu)送(song)(song)(song)方向上(shang)跳躍并(bing)垂直(zhi)滾動，這(zhe)降低了輸(shu)(shu)(shu)送(song)(song)(song)效(xiao)率，消耗大量并(bing)加速(su)(su)設(she)備(bei)的磨(mo)損。

在工(gong)業(ye)發達國家，滾(gun)筒(tong)(tong)輸(shu)送(song)(song)機的(de)(de)(de)(de)各種通用和(he)輥子的(de)(de)(de)(de)規格品(pin)種應(ying)有(you)盡(jin)有(you)，在機械、化工(gong)、輕工(gong)、食品(pin)、冶金、建材、倉(cang)庫(ku)、郵電、物資分配中心等(deng)(deng)都得到了廣(guang)泛應(ying)用。在滾(gun)筒(tong)(tong)輸(shu)送(song)(song)機的(de)(de)(de)(de)結(jie)(jie)(jie)構(gou)設計方(fang)面，包括滾(gun)筒(tong)(tong)輸(shu)送(song)(song)機的(de)(de)(de)(de)輥子本身結(jie)(jie)(jie)構(gou)、輥子的(de)(de)(de)(de)傳動方(fang)式、輥子的(de)(de)(de)(de)安裝(zhuang)固定結(jie)(jie)(jie)構(gou)、彎曲輸(shu)送(song)(song)段的(de)(de)(de)(de)結(jie)(jie)(jie)構(gou)、實(shi)現(xian)物品(pin)積放的(de)(de)(de)(de)結(jie)(jie)(jie)構(gou)方(fang)式，伸縮輸(shu)送(song)(song)機廠，以及類似回(hui)轉臺、轉載(zai)裝(zhuang)置(zhi)、極限(xian)力(li)矩聯(lian)軸器、傳感(gan)控制器等(deng)(deng)其(qi)它附件的(de)(de)(de)(de)結(jie)(jie)(jie)構(gou)設計，美國德國、英國、法國、前蘇聯(lian)等(deng)(deng)工(gong)業(ye)發達國家均(jun)有(you)許多發明。例如，德國研究(jiu)發明了一(yi)種減少積放壓力(li)的(de)(de)(de)(de)輥子輸(shu)送(song)(song)機結(jie)(jie)(jie)構(gou)，其(qi)在如何(he)減少積放壓力(li)方(fang)面是(shi)相當(dang)杰出的(de)(de)(de)(de)。

螺旋輸(shu)送(song)(song)(song)機的(de)螺旋葉(xie)片(pian)是(shi)(shi)輸(shu)送(song)(song)(song)機一重(zhong)要部(bu)件，其在形式上，伸縮(suo)輸(shu)送(song)(song)(song)機價(jia)格(ge)，是(shi)(shi)有(you)有(you)軸(zhou)(zhou)(zhou)葉(xie)片(pian)和(he)(he)無(wu)軸(zhou)(zhou)(zhou)葉(xie)片(pian)這兩種，并(bing)且，它(ta)們是(shi)(shi)有(you)不同特點和(he)(he)應(ying)用范圍。有(you)軸(zhou)(zhou)(zhou)葉(xie)片(pian)，其適用于水平或輕微傾斜的(de)輸(shu)送(song)(song)(song)中，主要是(shi)(shi)用來輸(shu)送(song)(song)(song)松散狀(zhuang)(zhuang)(zhuang)、粉狀(zhuang)(zhuang)(zhuang)或顆粒狀(zhuang)(zhuang)(zhuang)物(wu)料，而無(wu)軸(zhou)(zhou)(zhou)葉(xie)片(pian)，在帶狀(zhuang)(zhuang)(zhuang)、塊狀(zhuang)(zhuang)(zhuang)和(he)(he)易(yi)纏(chan)繞(rao)物(wu)料的(de)輸(shu)送(song)(song)(song)上有(you)一定優勢。

想(xiang)要(yao)避免螺旋輸送(song)(song)機(ji)(ji)的(de)(de)(de)堵(du)塞(sai)問題，我們應做到的(de)(de)(de)有：首先(xian)，是(shi)對需要(yao)輸送(song)(song)的(de)(de)(de)物料進(jin)行(xing)清理，清掉(diao)其中大的(de)(de)(de)雜質和纖維(wei)性雜質;其次(ci)，溧陽伸縮(suo)輸送(song)(song)機(ji)(ji)，盡可能減(jian)小懸掛軸(zhou)承(cheng)的(de)(de)(de)橫向尺寸，以降低物料通過中間軸(zhou)承(cheng)時發生堵(du)塞(sai)的(de)(de)(de)幾率。此外，合理和正確確定(ding)輸送(song)(song)機(ji)(ji)的(de)(de)(de)技術參數，保(bao)證輸送(song)(song)機(ji)(ji)的(de)(de)(de)正常運(yun)行(xing)。
