四川圓管輸送機缺點（二）

核心提示：盡管從結構上來看，圓管帶式輸送機不會

四川(chuan)圓管輸送(song)機缺(que)點（二）

(5)輸送帶(dai)扭轉

盡管從結構上來(lai)看，圓管帶式(shi)輸(shu)(shu)送機不會產生(sheng)如同通用帶式(shi)輸(shu)(shu)送機的輸(shu)(shu)送帶跑(pao)偏(pian)問(wen)題

是存在輸送帶(dai)的(de)(de)扭轉問題，嚴重時(shi)，會使輸送帶(dai)的(de)(de)邊緣進入兩個(ge)托輥的(de)(de)間隙內，造(zao)成輸送帶(dai)的(de)(de)損壞(huai)。

(6)托(tuo)輥受力集(ji)中，導致磨損嚴重

由于運行中圓(yuan)管(guan)帶式輸(shu)(shu)送(song)(song)機(ji)的(de)每個(ge)托(tuo)輥(gun)組中的(de)每節托(tuo)輥(gun)與輸(shu)(shu)送(song)(song)帶接(jie)觸(chu)為(wei)點接(jie)觸(chu)，圓(yuan)管(guan)帶式輸(shu)(shu)送(song)(song)機(ji)運行一段(duan)時間后，將會(hui)造成(cheng)每節托(tuo)輥(gun)中部磨損以致托(tuo)輥(gun)報廢。在(zai)輸(shu)(shu)送(song)(song)機(ji)設計時，在(zai)增強托(tuo)輥(gun)的(de)性能及結構(gou)上應采取(qu)措施(shi)，以增加托(tuo)輥(gun)的(de)使用(yong)壽(shou)命。

原理與結構：

圓(yuan)管(guan)(guan)帶(dai)(dai)(dai)式(shi)輸(shu)送(song)(song)(song)(song)(song)機(ji)的(de)工(gong)作原(yuan)理與普(pu)通帶(dai)(dai)(dai)式(shi)輸(shu)送(song)(song)(song)(song)(song)機(ji)相同(tong)(tong)，也(ye)是依(yi)靠摩擦驅動(dong)使輸(shu)送(song)(song)(song)(song)(song)帶(dai)(dai)(dai)及物料(liao)(liao)(liao)移動(dong)，用(yong)按一定間距布置的(de)正六邊托輥(gun)(gun)(gun)(gun)組(zu)強制把(ba)輸(shu)送(song)(song)(song)(song)(song)帶(dai)(dai)(dai)卷成(cheng)圓(yuan)管(guan)(guan)狀(zhuang)，將散狀(zhuang)物料(liao)(liao)(liao)包裹起(qi)來輸(shu)送(song)(song)(song)(song)(song)。圓(yuan)管(guan)(guan)帶(dai)(dai)(dai)式(shi)輸(shu)送(song)(song)(song)(song)(song)機(ji)的(de)頭(tou)部(bu)、尾部(bu)、受料(liao)(liao)(liao)點、卸(xie)料(liao)(liao)(liao)點、拉緊(jin)裝置等(deng)在(zai)結(jie)構(gou)上與普(pu)通帶(dai)(dai)(dai)式(shi)輸(shu)送(song)(song)(song)(song)(song)機(ji)基本相同(tong)(tong)，輸(shu)送(song)(song)(song)(song)(song)帶(dai)(dai)(dai)在(zai)尾部(bu)過(guo)渡段受料(liao)(liao)(liao)后，逐漸將其(qi)卷成(cheng)圓(yuan)管(guan)(guan)狀(zhuang)進行物料(liao)(liao)(liao)密(mi)閉輸(shu)送(song)(song)(song)(song)(song)，到頭(tou)部(bu)過(guo)渡段再逐漸展開成(cheng)平形(xing)直至卸(xie)料(liao)(liao)(liao)。除輸(shu)送(song)(song)(song)(song)(song)機(ji)中(zhong)間部(bu)分把(ba)輸(shu)送(song)(song)(song)(song)(song)帶(dai)(dai)(dai)卷成(cheng)圓(yuan)管(guan)(guan)狀(zhuang)與普(pu)通輸(shu)送(song)(song)(song)(song)(song)機(ji)不同(tong)(tong)外(wai)，而(er)過(guo)渡段的(de)長度及其(qi)槽形(xing)托輥(gun)(gun)(gun)(gun)組(zu)的(de)布置形(xing)式(shi)也(ye)不同(tong)(tong)，每一組(zu)槽形(xing)托輥(gun)(gun)(gun)(gun)的(de)角度和寬(kuan)度都要隨(sui)著輸(shu)送(song)(song)(song)(song)(song)帶(dai)(dai)(dai)變化，使每組(zu)托輥(gun)(gun)(gun)(gun)的(de)輪廓線與輸(shu)送(song)(song)(song)(song)(song)帶(dai)(dai)(dai)在(zai)任(ren)意斷面上的(de)形(xing)狀(zhuang)吻合(he)，使托輥(gun)(gun)(gun)(gun)起(qi)到支(zhi)撐作用(yong)。
