四川圓管輸送機缺點（二）

核心提示：盡管從結(jie)構上來(lai)看，圓(yuan)管帶式輸送機不會

四川(chuan)圓(yuan)管(guan)輸(shu)送機缺點（二(er)）

(5)輸(shu)送帶扭(niu)轉

盡管從結構(gou)上來看，圓管帶(dai)式輸(shu)送機不會(hui)產生如同(tong)通(tong)用帶(dai)式輸(shu)送機的輸(shu)送帶(dai)跑(pao)偏問題

是存在輸(shu)(shu)送(song)帶的(de)扭轉問題，嚴重時，會使輸(shu)(shu)送(song)帶的(de)邊(bian)緣進入兩(liang)個托輥的(de)間隙內，造(zao)成輸(shu)(shu)送(song)帶的(de)損壞。

(6)托輥受力(li)集中(zhong)，導致磨損嚴重

由于運(yun)行(xing)中(zhong)圓(yuan)管帶(dai)式輸(shu)送(song)機的(de)每個托輥(gun)組中(zhong)的(de)每節托輥(gun)與輸(shu)送(song)帶(dai)接觸為點接觸，圓(yuan)管帶(dai)式輸(shu)送(song)機運(yun)行(xing)一段時間后，將(jiang)會造成每節托輥(gun)中(zhong)部磨損(sun)以(yi)致托輥(gun)報廢。在輸(shu)送(song)機設計(ji)時，在增(zeng)強托輥(gun)的(de)性能及結構上應(ying)采取措施(shi)，以(yi)增(zeng)加(jia)托輥(gun)的(de)使用壽命。

原理(li)與結構：

圓管(guan)帶(dai)式(shi)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)機的(de)(de)(de)工作(zuo)原理與(yu)普(pu)通帶(dai)式(shi)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)機相同(tong)，也(ye)是依(yi)靠摩擦驅動(dong)使輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)帶(dai)及物料(liao)移動(dong)，用按(an)一定間距布置(zhi)(zhi)的(de)(de)(de)正六邊托(tuo)(tuo)輥(gun)組(zu)強制把輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)帶(dai)卷(juan)(juan)成(cheng)圓管(guan)狀，將(jiang)散狀物料(liao)包裹起來輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)。圓管(guan)帶(dai)式(shi)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)機的(de)(de)(de)頭部(bu)(bu)、尾部(bu)(bu)、受(shou)(shou)料(liao)點、卸料(liao)點、拉緊裝置(zhi)(zhi)等在(zai)(zai)結構上與(yu)普(pu)通帶(dai)式(shi)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)機基(ji)本相同(tong)，輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)帶(dai)在(zai)(zai)尾部(bu)(bu)過(guo)(guo)渡(du)段(duan)(duan)(duan)受(shou)(shou)料(liao)后，逐(zhu)漸將(jiang)其(qi)卷(juan)(juan)成(cheng)圓管(guan)狀進(jin)行物料(liao)密閉輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)，到頭部(bu)(bu)過(guo)(guo)渡(du)段(duan)(duan)(duan)再逐(zhu)漸展(zhan)開成(cheng)平(ping)形直至卸料(liao)。除輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)機中間部(bu)(bu)分把輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)帶(dai)卷(juan)(juan)成(cheng)圓管(guan)狀與(yu)普(pu)通輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)機不同(tong)外，而(er)過(guo)(guo)渡(du)段(duan)(duan)(duan)的(de)(de)(de)長度及其(qi)槽(cao)形托(tuo)(tuo)輥(gun)組(zu)的(de)(de)(de)布置(zhi)(zhi)形式(shi)也(ye)不同(tong)，每(mei)一組(zu)槽(cao)形托(tuo)(tuo)輥(gun)的(de)(de)(de)角度和(he)寬度都要(yao)隨著輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)帶(dai)變化(hua)，使每(mei)組(zu)托(tuo)(tuo)輥(gun)的(de)(de)(de)輪廓線與(yu)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)帶(dai)在(zai)(zai)任意斷面上的(de)(de)(de)形狀吻合，使托(tuo)(tuo)輥(gun)起到支撐作(zuo)用。
