一、卷揚機的卷筒是什么部位
卷揚機是一(yi)種輕小(xiao)型起重設備,卷筒(tong)是它的(de)一(yi)個(ge)重要(yao)部件,那么(me)卷筒(tong)是哪個(ge)部位呢?
據了(le)解,卷(juan)(juan)(juan)揚機的卷(juan)(juan)(juan)筒就是卷(juan)(juan)(juan)揚機上(shang)容(rong)納鋼(gang)絲(si)繩的筒狀物(wu)體,也是卷(juan)(juan)(juan)揚機的主體,鋼(gang)絲(si)繩就纏繞在(zai)上(shang)面。一(yi)般(ban)卷(juan)(juan)(juan)揚機的卷(juan)(juan)(juan)筒要求節(jie)徑應不小于所(suo)使用(yong)鋼(gang)絲(si)繩公稱直徑的19倍,邊緣外周至最外層鋼(gang)絲(si)繩的距(ju)離應不小于鋼(gang)絲(si)繩直徑的1.5倍。
二、卷揚機一般有幾個卷筒
卷(juan)(juan)揚(yang)機(ji)的(de)卷(juan)(juan)筒(tong)(tong)(tong)作為(wei)其核心(xin)部件(jian),一般(ban)有(you)多(duo)種規格:常見的(de)小型(xing)卷(juan)(juan)揚(yang)機(ji)一般(ban)是只有(you)一個(ge)卷(juan)(juan)筒(tong)(tong)(tong)的(de),也稱單(dan)卷(juan)(juan)筒(tong)(tong)(tong)卷(juan)(juan)揚(yang)機(ji);也有(you)的(de)卷(juan)(juan)揚(yang)機(ji)有(you)兩個(ge)卷(juan)(juan)筒(tong)(tong)(tong),這(zhe)種就叫雙(shuang)卷(juan)(juan)筒(tong)(tong)(tong)卷(juan)(juan)揚(yang)機(ji);還有(you)一些大型(xing)的(de)卷(juan)(juan)揚(yang)機(ji)具有(you)三個(ge)或三個(ge)以上的(de)卷(juan)(juan)筒(tong)(tong)(tong),這(zhe)種稱為(wei)多(duo)卷(juan)(juan)筒(tong)(tong)(tong)卷(juan)(juan)揚(yang)機(ji)。
三、雙卷筒卷揚機與單卷筒卷揚機哪個好
雙卷(juan)(juan)筒(tong)卷(juan)(juan)揚(yang)機和單(dan)卷(juan)(juan)筒(tong)卷(juan)(juan)揚(yang)機相比,哪(na)個更好主(zhu)要看使(shi)用環境:
從性能方面看,雙卷筒和單卷筒好比車道一樣,雙車道肯定比單車道效率更高,單卷筒的卷揚機只能連接做上下升降運動,雙卷筒的卷揚機在工作時(shi)可以(yi)一個(ge)上升(sheng)一個(ge)下(xia)降,提高使用效率。
雙(shuang)(shuang)卷(juan)(juan)筒卷(juan)(juan)揚(yang)(yang)機效率(lv)更(geng)高(gao)(gao),主(zhu)要適用于提升量大的(de)場所,但(dan)相對來說,它的(de)體積也更(geng)大,價(jia)格更(geng)高(gao)(gao),如果(guo)單卷(juan)(juan)筒卷(juan)(juan)揚(yang)(yang)機可以搞(gao)定的(de)話(hua),就沒有(you)必要用雙(shuang)(shuang)卷(juan)(juan)筒卷(juan)(juan)揚(yang)(yang)機了(le)。
