螺(luo)旋(xuan)輸(shu)送(song)(song)(song)機設備(bei)從(cong)外型上來區(qu)分的話(hua)，主要(yao)可(ke)分為U型和管式(shi)兩種；U型螺(luo)旋(xuan)輸(shu)送(song)(song)(song)機的密(mi)封性相對不如管式(shi)螺(luo)旋(xuan)輸(shu)送(song)(song)(song)機設備(bei)；如果(guo)是輸(shu)送(song)(song)(song)粉料的話(hua)，建議(yi)采(cai)用(yong)圓管式(shi)螺(luo)旋(xuan)輸(shu)送(song)(song)(song)機設備(bei)，顆粒狀物料可(ke)以采(cai)用(yong)U型螺(luo)旋(xuan)輸(shu)送(song)(song)(song)機設備(bei)；如果(guo)里面壓力，則需(xu)提(ti)前說明，加工時候需(xu)要(yao)廠家定制(zhi)！

管(guan)(guan)式螺(luo)(luo)旋輸送(song)(song)(song)機(ji)(ji)設(she)備(bei)的機(ji)(ji)身直接是(shi)采用一(yi)根(gen)圓型鋼管(guan)(guan)，因此密(mi)封(feng)性(xing)相(xiang)對比較好(hao)；U型螺(luo)(luo)旋輸送(song)(song)(song)機(ji)(ji)設(she)備(bei)的機(ji)(ji)蓋為瓦(wa)片式并用蓋扣夾緊在機(ji)(ji)殼上，若需改進密(mi)封(feng)性(xing)能，用戶(hu)可(ke)自行(xing)在機(ji)(ji)蓋與機(ji)(ji)殼間加粗帆布；兩種螺(luo)(luo)旋輸送(song)(song)(song)機(ji)(ji)各(ge)有(you)(you)利弊(bi)，U型螺(luo)(luo)旋輸送(song)(song)(song)機(ji)(ji)設(she)備(bei)的密(mi)封(feng)性(xing)沒有(you)(you)管(guan)(guan)式的好(hao)，但是(shi)其結構，利于用戶(hu)清理里(li)面(mian)堆積的物料，方便(bian)觀察、檢測、維修(xiu)。

螺(luo)旋輸(shu)(shu)(shu)送(song)機設備對(dui)于粉狀物(wu)料(liao)的輸(shu)(shu)(shu)送(song)是比較常見的，螺(luo)旋輸(shu)(shu)(shu)送(song)機設備不僅要(yao)(yao)保證物(wu)料(liao)輸(shu)(shu)(shu)送(song)持續、穩定，輸(shu)(shu)(shu)送(song)速度滿足相應的要(yao)(yao)求，而(er)且物(wu)料(liao)在輸(shu)(shu)(shu)送(song)過程中沒有遺灑(sa)、飛散等現象。

針對以(yi)上要(yao)求，并在充分考慮了粉(fen)狀物料特性的基礎上，對螺旋輸送機(ji)的密封性是(shi)一個比較重(zhong)要(yao)的問題：即如果螺旋輸送機(ji)設(she)備(bei)的軸(zhou)(zhou)(zhou)與軸(zhou)(zhou)(zhou)承(cheng)座密封效果不好，細粉(fen)經(jing)常順軸(zhou)(zhou)(zhou)漏出而進入軸(zhou)(zhou)(zhou)承(cheng)座內，造成(cheng)軸(zhou)(zhou)(zhou)承(cheng)的損(sun)壞，導致(zhi)檢(jian)修(xiu)頻繁，影響(xiang)設(she)備(bei)的穩定運行；所以(yi)設(she)法解決(jue)螺旋輸送機(ji)設(she)備(bei)的軸(zhou)(zhou)(zhou)承(cheng)密封問題，是(shi)減少維(wei)修(xiu)工作量，提高螺旋輸送機(ji)設(she)備(bei)穩定運行效率的關鍵。
