影響(xiang)振動(dong)篩篩分的因(yin)素有哪些?
振(zhen)動篩篩分(fen)過(guo)程中會受(shou)外(wai)界(jie)的(de)因(yin)素影(ying)響(xiang),外(wai)界(jie)的(de)影(ying)響(xiang)會造成(cheng)振(zhen)動篩產量上出(chu)現(xian)問(wen)題(ti),而且(qie)還會造成(cheng)壽(shou)命上的(de)減(jian)少,那(nei)么(me)今天(tian)小編就給大家介紹下(xia),影(ying)響(xiang)篩分(fen)過(guo)程的(de)因(yin)素大體可以分(fen)為三類:
1、物(wu)(wu)料(liao)本身的流(liu)動(dong)性,物(wu)(wu)料(liao)本身若(ruo)是流(liu)動(dong)性差,相(xiang)對(dui)于振(zhen)動(dong)篩(shai)(shai)來說,篩(shai)(shai)分效(xiao)果就并不是很(hen)好;若(ruo)是在篩(shai)(shai)分過程中,網上(shang)物(wu)(wu)遠(yuan)遠(yuan)小于網下物(wu)(wu)的話,篩(shai)(shai)分就會很(hen)容易。
2、篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)性質機器(qi)結構參(can)數的(de)影(ying)響,振動(dong)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)時(shi)使粒(li)子和篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)作(zuo)垂直運動(dong),所以(yi)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)分(fen)效率高,生(sheng)(sheng)產能力大。而粒(li)子與篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)相對運動(dong)主要是平行運動(dong)的(de)棒條(tiao)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)、平面(mian)(mian)振動(dong)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)、筒篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)等,其篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)分(fen)效率和生(sheng)(sheng)產能力都低。對于(yu)一定的(de)物(wu)料而言(yan),篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)子的(de)生(sheng)(sheng)產率和篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)分(fen)效率決(jue)(jue)定于(yu)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)孔尺寸。生(sheng)(sheng)產率取決(jue)(jue)于(yu)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)寬(kuan)(kuan)度,篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)寬(kuan)(kuan)生(sheng)(sheng)產率高。
3、精(jing)細篩(shai)(shai)分(fen)(fen)設(she)備的(de)篩(shai)(shai)分(fen)(fen)效(xiao)率(lv)取決(jue)于(yu)篩(shai)(shai)面(mian)長(chang)(chang)度(du),振動(dong)篩(shai)(shai)篩(shai)(shai)面(mian)長(chang)(chang)篩(shai)(shai)分(fen)(fen)效(xiao)率(lv)高(gao),一般長(chang)(chang)寬比(bi)為2。有效(xiao)的(de)篩(shai)(shai)子面(mian)積愈(yu)大(da),則篩(shai)(shai)面(mian)的(de)單位面(mian)積生(sheng)產率(lv)和篩(shai)(shai)分(fen)(fen)效(xiao)率(lv)愈(yu)高(gao)。
4、物料(liao)的(de)(de)(de)粘(zhan)(zhan)性。正常(chang)情況來說,物料(liao)是沒(mei)有(you)粘(zhan)(zhan)性的(de)(de)(de),這個時(shi)候篩分就(jiu)(jiu)處于(yu)正常(chang)篩分,若是物料(liao)有(you)粘(zhan)(zhan)性,在篩分過(guo)程中就(jiu)(jiu)會出現糊網的(de)(de)(de)情況,糊網是比較難解決的(de)(de)(de)一個問(wen)題,若是糊網嚴重的(de)(de)(de)話,需要考慮更換設備。
5、篩(shai)孔(kong)的大小。若是設備(bei)在(zai)選(xuan)擇篩(shai)孔(kong)時,選(xuan)擇錯(cuo)誤,會(hui)導致(zhi)(zhi)物料篩(shai)分(fen)受影(ying)響,嚴重的話(hua)會(hui)導致(zhi)(zhi)機器不能夠用(yong),這個(ge)時候需(xu)要(yao)考慮(lv)到更換篩(shai)網。
另(ling)外(wai)還(huan)有(you)(you)一些情況可能(neng)導致設(she)備篩(shai)(shai)(shai)分效率出現(xian)問題,啟(qi)動(dong)前要檢(jian)(jian)(jian)查篩(shai)(shai)(shai)網(wang)有(you)(you)無破損(sun),每一組束環是否(fou)(fou)鎖緊;啟(qi)動(dong)時(shi)注意觀察(cha)機器有(you)(you)無異常聲響,如果有(you)(you)應立即停車檢(jian)(jian)(jian)查。另(ling)外(wai)還(huan)要注意觀察(cha)電(dian)流和振(zhen)動(dong)是否(fou)(fou)正常;設(she)備使(shi)用后要及時(shi)進行清理;定(ding)時(shi)檢(jian)(jian)(jian)查篩(shai)(shai)(shai)網(wang)、彈(dan)簧有(you)(you)無破損(sun),如果發現(xian)破損(sun)應及時(shi)修復或者更換;電(dian)機運(yun)行兩周左右,補充一次(ci)適時(shi)的(de)鋰基(ji)潤(run)滑(hua)脂。累計運(yun)行1500小時(shi),檢(jian)(jian)(jian)查軸承,若(ruo)損(sun)壞時(shi)立即清理干(gan)凈;要對振(zhen)動(dong)篩(shai)(shai)(shai)的(de)各部(bu)的(de)螺栓定(ding)期進行檢(jian)(jian)(jian)查、緊固。
激(ji)振(zhen)器一般運行4至6個月小修(xiu)(xiu)一次,一年大修(xiu)(xiu)一次,小修(xiu)(xiu)時清(qing)除(chu)機體上的積塵、污垢,檢(jian)查螺栓(shuan)是否松(song)動,及時清(qing)除(chu)隱患。大修(xiu)(xiu)時將(jiang)激(ji)振(zhen)器拆卸下來,行小修(xiu)(xiu)項目,然后將(jiang)激(ji)振(zhen)器全(quan)部拆開,清(qing)洗各個零件,定(ding)時檢(jian)查軸承和軸的磨(mo)損程(cheng)度,更換損壞的零件,再進(jin)行組裝,裝配完畢(bi),需進(jin)行空(kong)轉(zhuan)試車在正式(shi)投入(ru)使用。
