四(si)川圓管輸送機(ji)缺點（二）

(5)輸(shu)送(song)帶扭(niu)轉

盡管從結構上(shang)來看，圓管帶式輸(shu)送機不會(hui)產生如同通用帶式輸(shu)送機的輸(shu)送帶跑偏問(wen)題

是(shi)存在輸(shu)送(song)(song)帶的(de)(de)扭轉問題，嚴重時，會使輸(shu)送(song)(song)帶的(de)(de)邊緣進入兩個托輥的(de)(de)間隙內，造成(cheng)輸(shu)送(song)(song)帶的(de)(de)損壞。

(6)托輥受力集中，導致磨損嚴重

由于運行(xing)中圓管帶式輸送機的(de)每(mei)個托輥(gun)(gun)(gun)(gun)(gun)組中的(de)每(mei)節(jie)托輥(gun)(gun)(gun)(gun)(gun)與輸送帶接觸為點接觸，圓管帶式輸送機運行(xing)一段時(shi)(shi)間后，將會造成每(mei)節(jie)托輥(gun)(gun)(gun)(gun)(gun)中部磨損以致托輥(gun)(gun)(gun)(gun)(gun)報廢(fei)。在輸送機設計時(shi)(shi)，在增強托輥(gun)(gun)(gun)(gun)(gun)的(de)性能及(ji)結構上(shang)應(ying)采取措施(shi)，以增加(jia)托輥(gun)(gun)(gun)(gun)(gun)的(de)使用壽命。

原理與結構(gou)：

圓管帶(dai)式輸(shu)送(song)(song)(song)機(ji)(ji)的(de)(de)(de)工作(zuo)原理與普(pu)(pu)通(tong)帶(dai)式輸(shu)送(song)(song)(song)機(ji)(ji)相(xiang)同(tong)，也是依靠(kao)摩擦驅動使(shi)輸(shu)送(song)(song)(song)帶(dai)及物料(liao)(liao)移動，用按一定間距布置(zhi)的(de)(de)(de)正六邊托(tuo)(tuo)輥(gun)組強制把輸(shu)送(song)(song)(song)帶(dai)卷成(cheng)圓管狀，將(jiang)(jiang)散狀物料(liao)(liao)包裹起(qi)來(lai)輸(shu)送(song)(song)(song)。圓管帶(dai)式輸(shu)送(song)(song)(song)機(ji)(ji)的(de)(de)(de)頭部、尾部、受(shou)料(liao)(liao)點(dian)(dian)、卸料(liao)(liao)點(dian)(dian)、拉緊(jin)裝置(zhi)等在(zai)(zai)(zai)結構上(shang)與普(pu)(pu)通(tong)帶(dai)式輸(shu)送(song)(song)(song)機(ji)(ji)基(ji)本相(xiang)同(tong)，輸(shu)送(song)(song)(song)帶(dai)在(zai)(zai)(zai)尾部過(guo)(guo)渡段受(shou)料(liao)(liao)后(hou)，逐漸將(jiang)(jiang)其卷成(cheng)圓管狀進行(xing)物料(liao)(liao)密閉輸(shu)送(song)(song)(song)，到(dao)(dao)頭部過(guo)(guo)渡段再逐漸展(zhan)開(kai)成(cheng)平形(xing)(xing)直至卸料(liao)(liao)。除輸(shu)送(song)(song)(song)機(ji)(ji)中間部分把輸(shu)送(song)(song)(song)帶(dai)卷成(cheng)圓管狀與普(pu)(pu)通(tong)輸(shu)送(song)(song)(song)機(ji)(ji)不(bu)同(tong)外，而過(guo)(guo)渡段的(de)(de)(de)長度及其槽形(xing)(xing)托(tuo)(tuo)輥(gun)組的(de)(de)(de)布置(zhi)形(xing)(xing)式也不(bu)同(tong)，每一組槽形(xing)(xing)托(tuo)(tuo)輥(gun)的(de)(de)(de)角度和寬度都要隨著輸(shu)送(song)(song)(song)帶(dai)變化，使(shi)每組托(tuo)(tuo)輥(gun)的(de)(de)(de)輪廓線與輸(shu)送(song)(song)(song)帶(dai)在(zai)(zai)(zai)任意斷面上(shang)的(de)(de)(de)形(xing)(xing)狀吻合，使(shi)托(tuo)(tuo)輥(gun)起(qi)到(dao)(dao)支撐(cheng)作(zuo)用。
