螺(luo)(luo)(luo)(luo)桿(gan)(gan)真空(kong)泵在實際使(shi)用(yong)(yong)過程(cheng)中(zhong)運行相(xiang)對(dui)穩定,但有些(xie)用(yong)(yong)戶反映,真正的(de)(de)(de)螺(luo)(luo)(luo)(luo)桿(gan)(gan)真空(kong)泵運行時(shi)間(jian)(jian)長,磨(mo)(mo)損(sun)(sun)(sun)嚴重,影(ying)響(xiang)真空(kong)泵的(de)(de)(de)正常生(sheng)產(chan)和使(shi)用(yong)(yong)效果(guo)。此(ci)時(shi),我們(men)需要知道是什么(me)造成了(le)磨(mo)(mo)損(sun)(sun)(sun),然后盡可能減少(shao)磨(mo)(mo)損(sun)(sun)(sun)。 1.在收縮(suo)和均化(hua)零件(jian)中(zhong),塑(su)(su)料(liao)(liao)(liao)(liao)熔化(hua)狀態(tai)不(bu)有序,不(bu)均勻(yun)會增(zeng)(zeng)加(jia)(jia)磨(mo)(mo)損(sun)(sun)(sun)。 2.由(you)于材(cai)料(liao)(liao)(liao)(liao)沒有塑(su)(su)化(hua)或與(yu)金(jin)(jin)屬異物(wu)混合,螺(luo)(luo)(luo)(luo)桿(gan)(gan)真空(kong)泵的(de)(de)(de)滾(gun)動扭矩(ju)突然增(zeng)(zeng)加(jia)(jia),超(chao)過螺(luo)(luo)(luo)(luo)桿(gan)(gan)的(de)(de)(de)強(qiang)度,然后導(dao)致磨(mo)(mo)損(sun)(sun)(sun)。 3.有些(xie)塑(su)(su)料(liao)(liao)(liao)(liao)是增(zeng)(zeng)強(qiang)的(de)(de)(de),如(ru)玻(bo)璃纖維(wei)、礦物(wu)和其他填料(liao)(liao)(liao)(liao)。這些(xie)物(wu)質(zhi)對(dui)金(jin)(jin)屬材(cai)料(liao)(liao)(liao)(liao)的(de)(de)(de)摩擦(ca)力(li)大(da)于熔融塑(su)(su)料(liao)(liao)(liao)(liao)的(de)(de)(de)摩擦(ca)力(li)。 4.當粒狀塑(su)(su)料(liao)(liao)(liao)(liao)從(cong)料(liao)(liao)(liao)(liao)斗進入的(de)(de)(de)桶中(zhong)排出(chu)時(shi),它(ta)們(men)首(shou)先到達料(liao)(liao)(liao)(liao)斗部分(fen)。干摩擦(ca)不(bu)可避免(mian)地發(fa)生(sheng)在進料(liao)(liao)(liao)(liao)位(wei)置。持久性這些(xie)塑(su)(su)料(liao)(liao)(liao)(liao)熔化(hua)不(bu)均勻(yun),容易形成螺(luo)(luo)(luo)(luo)桿(gan)(gan)內壁(bi)桿(gan)(gan)真空(kong)泵,增(zeng)(zeng)加(jia)(jia)螺(luo)(luo)(luo)(luo)桿(gan)(gan)的(de)(de)(de)外部磨(mo)(mo)損(sun)(sun)(sun)。 5.如(ru)果(guo)在注射成型過程(cheng)中(zhong)采用(yong)(yong)高速轉換來增(zeng)(zeng)加(jia)(jia)剪切(qie)力(li),增(zeng)(zeng)強(qiang)材(cai)料(liao)(liao)(liao)(liao)也會產(chan)生(sheng)相(xiang)應(ying)(ying)的(de)(de)(de)撕(si)裂纖維(wei)。撕(si)裂的(de)(de)(de)纖維(wei)含(han)有尖端(duan),大(da)大(da)提高了(le)耐(nai)磨(mo)(mo)性。 6.當無機(ji)(ji)礦物(wu)在金(jin)(jin)屬表面迅速折疊時(shi),它(ta)們(men)的(de)(de)(de)刮擦(ca)效果(guo)非常大(da)。所以速度不(bu)應(ying)(ying)該太高。 7.碳酸鈣和玻(bo)璃纖維(wei)等填充材(cai)料(liao)(liao)(liao)(liao)會加(jia)(jia)速螺(luo)(luo)(luo)(luo)桿(gan)(gan)和機(ji)(ji)筒(tong)(tong)(tong)的(de)(de)(de)磨(mo)(mo)損(sun)(sun)(sun)。做這種事情的(de)(de)(de)人 8.螺(luo)(luo)(luo)(luo)桿(gan)(gan)真空(kong)泵在筒(tong)(tong)(tong)體中(zhong)滾(gun)動,物(wu)料(liao)(liao)(liao)(liao)與(yu)筒(tong)(tong)(tong)體的(de)(de)(de)沖突逐漸導(dao)致螺(luo)(luo)(luo)(luo)桿(gan)(gan)的(de)(de)(de)工作外觀(guan)和筒(tong)(tong)(tong)體磨(mo)(mo)損(sun)(sun)(sun)。螺(luo)(luo)(luo)(luo)桿(gan)(gan)的(de)(de)(de)直徑(jing)逐漸減小(xiao),圓(yuan)筒(tong)(tong)(tong)的(de)(de)(de)內徑(jing)逐漸增(zeng)(zeng)大(da)。這樣,隨著螺(luo)(luo)(luo)(luo)桿(gan)(gan)和圓(yuan)筒(tong)(tong)(tong)的(de)(de)(de)磨(mo)(mo)損(sun)(sun)(sun),螺(luo)(luo)(luo)(luo)桿(gan)(gan)和圓(yuan)筒(tong)(tong)(tong)之間(jian)(jian)的(de)(de)(de)直徑(jing)間(jian)(jian)隙變大(da)。 9.由(you)于筒(tong)(tong)(tong)體前面的(de)(de)(de)頭部和導(dao)向板的(de)(de)(de)阻力(li)不(bu)變,擠出(chu)材(cai)料(liao)(liao)(liao)(liao)流量的(de)(de)(de)泄漏增(zeng)(zeng)加(jia)(jia),即材(cai)料(liao)(liao)(liao)(liao)流量從(cong)直徑(jing)間(jian)(jian)隙向進料(liao)(liao)(liao)(liao)方向增(zeng)(zeng)加(jia)(jia)。 由(you)于螺(luo)(luo)(luo)(luo)桿(gan)(gan)真空(kong)...
