目前皮帶脫水機適用于顆粒度小,并且能將濾料厚度達到3mm以上,并且真空作用下連續進行吸濾和干燥的情況下,能將濾布自動調偏等優點,對此這樣的設備要是出現故障該怎么辦,今日小編就來為大家一起來分享一下吧!
一、皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)跑(pao)(pao)(pao)(pao)偏(pian):皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)跑(pao)(pao)(pao)(pao)偏(pian)是(shi)(shi)(shi)真(zhen)空(kong)皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)機常(chang)見的(de)(de)(de)問題(ti)(ti),也是(shi)(shi)(shi)難解(jie)決的(de)(de)(de)問題(ti)(ti).為了保(bao)護系(xi)統(tong)(tong),一般(ban)(ban)都會在(zai)皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)兩邊(bian)設置皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)跑(pao)(pao)(pao)(pao)偏(pian)的(de)(de)(de)傳感器(qi).當(dang)皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)跑(pao)(pao)(pao)(pao)偏(pian)后(hou),傳感器(qi)就會發送(song)信(xin)號到DCS,發出皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)跑(pao)(pao)(pao)(pao)偏(pian)報警信(xin)號,皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)逐漸偏(pian)離中(zhong)心,真(zhen)空(kong)度明顯上升(sheng)且濾(lv)餅含水量增(zeng)大.當(dang)皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)跑(pao)(pao)(pao)(pao)偏(pian)達到一定程度后(hou),出于(yu)保(bao)護系(xi)統(tong)(tong)的(de)(de)(de)目的(de)(de)(de),系(xi)統(tong)(tong)會自動緊(jin)(jin)急停車.皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)跑(pao)(pao)(pao)(pao)偏(pian)一般(ban)(ban)是(shi)(shi)(shi)由于(yu)以(yi)下幾種(zhong)原(yuan)(yuan)因(yin)(yin)(yin)造成(cheng):皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)驅動輥(gun)(gun)(gun)(gun)和(he)皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)張緊(jin)(jin)輥(gun)(gun)(gun)(gun)的(de)(de)(de)問題(ti)(ti).這(zhe)可(ke)能有兩個(ge)(ge)原(yuan)(yuan)因(yin)(yin)(yin),一是(shi)(shi)(shi)皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)驅動輥(gun)(gun)(gun)(gun)和(he)皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)張緊(jin)(jin)輥(gun)(gun)(gun)(gun)不平(ping)行(xing);二是(shi)(shi)(shi)皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)張緊(jin)(jin)輥(gun)(gun)(gun)(gun)和(he)皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)驅動輥(gun)(gun)(gun)(gun)雖然平(ping)行(xing),但是(shi)(shi)(shi)卻沒(mei)有對(dui)中(zhong),也即輥(gun)(gun)(gun)(gun)的(de)(de)(de)軸線(xian)和(he)真(zhen)空(kong)室(shi)不垂直.這(zhe)個(ge)(ge)問題(ti)(ti)在(zai)工廠組裝的(de)(de)(de)時候就應該注意.如果是(shi)(shi)(shi)正在(zai)運行(xing)中(zhong),對(dui)于(yu)一種(zhong)原(yuan)(yuan)因(yin)(yin)(yin),則可(ke)以(yi)在(zai)停車后(hou)通過拉(la)對(dui)角線(xian)和(he)水平(ping)管或是(shi)(shi)(shi)水平(ping)儀來測定后(hou)調(diao)整,但要(yao)保(bao)證(zheng)(zheng)驅動輥(gun)(gun)(gun)(gun)的(de)(de)(de)位置正確;對(dui)于(yu)第二種(zhong)原(yuan)(yuan)因(yin)(yin)(yin)則需(xu)要(yao)重(zhong)新測量中(zhong)心點,根據中(zhong)心點調(diao)整輥(gun)(gun)(gun)(gun)筒直至合(he)格.還(huan)有一種(zhong)原(yuan)(yuan)因(yin)(yin)(yin)是(shi)(shi)(shi)皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)對(dui)接(jie)有問題(ti)(ti).這(zhe)是(shi)(shi)(shi)皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)跑(pao)(pao)(pao)(pao)偏(pian)中(zhong)嚴重(zhong)的(de)(de)(de)問題(ti)(ti),主要(yao)有斜接(jie)和(he)喇叭(ba)口(kou)兩種(zhong)問題(ti)(ti).出現這(zhe)種(zhong)問題(ti)(ti),除(chu)了更換新的(de)(de)(de)皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai),無法采取其他的(de)(de)(de)方法消除(chu)這(zhe)個(ge)(ge)誤(wu)差.一般(ban)(ban)在(zai)皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)對(dui)接(jie)時,應該多選(xuan)擇(ze)幾個(ge)(ge)點進行(xing)測量,以(yi)保(bao)證(zheng)(zheng)皮(pi)(pi)(pi)(pi)(pi)帶(dai)(dai)(dai)對(dui)接(jie)正確.二、濾(lv)布(bu)(bu)跑偏(pian)(pian)(pian)(pian):濾(lv)布(bu)(bu)跑偏(pian)(pian)(pian)(pian)也(ye)是(shi)真空(kong)皮(pi)帶機(ji)常見問題.一(yi)般(ban)的(de)(de)(de)(de)(de)(de)(de)皮(pi)帶機(ji)都會有濾(lv)布(bu)(bu)跑偏(pian)(pian)(pian)(pian)報警(jing)裝(zhuang)置(zhi)(zhi),并有自(zi)(zi)動(dong)糾(jiu)(jiu)偏(pian)(pian)(pian)(pian)裝(zhuang)置(zhi)(zhi).自(zi)(zi)動(dong)糾(jiu)(jiu)偏(pian)(pian)(pian)(pian)裝(zhuang)置(zhi)(zhi)一(yi)般(ban)由電動(dong)或是(shi)氣動(dong)兩種方(fang)式,啟動(dong)糾(jiu)(jiu)偏(pian)(pian)(pian)(pian)裝(zhuang)置(zhi)(zhi)由傳感(gan)器、氣源(yuan)分(fen)配器、調節(jie)氣囊組成.當濾(lv)布(bu)(bu)走偏(pian)(pian)(pian)(pian)時,氣源(yuan)分(fen)配器會根據濾(lv)布(bu)(bu)走偏(pian)(pian)(pian)(pian)的(de)(de)(de)(de)(de)(de)(de)方(fang)向向兩個(ge)調節(jie)氣囊分(fen)配壓(ya)縮空(kong)氣,進而調節(jie)輥(gun)筒(tong)角(jiao)度,達到糾(jiu)(jiu)正濾(lv)布(bu)(bu)走向的(de)(de)(de)(de)(de)(de)(de)作用.一(yi)般(ban)情況下(xia),調整(zheng)(zheng)好的(de)(de)(de)(de)(de)(de)(de)糾(jiu)(jiu)偏(pian)(pian)(pian)(pian)裝(zhuang)置(zhi)(zhi)能夠保(bao)證濾(lv)布(bu)(bu)自(zi)(zi)動(dong)糾(jiu)(jiu)偏(pian)(pian)(pian)(pian).這(zhe)里要(yao)注意(yi)(yi)的(de)(de)(de)(de)(de)(de)(de)是(shi),濾(lv)布(bu)(bu)在空(kong)轉、加水(shui)(shui)空(kong)負(fu)荷運轉轉和負(fu)荷運轉時均需調整(zheng)(zheng)傳感(gan)器的(de)(de)(de)(de)(de)(de)(de)位(wei)置(zhi)(zhi)和角(jiao)度.如果只是(shi)在空(kong)轉或是(shi)加水(shui)(shui)空(kong)負(fu)荷運轉的(de)(de)(de)(de)(de)(de)(de)時候調整(zheng)(zheng)糾(jiu)(jiu)偏(pian)(pian)(pian)(pian)裝(zhuang)置(zhi)(zhi),就會發生濾(lv)布(bu)(bu)跑偏(pian)(pian)(pian)(pian)現象,此(ci)時不須停車(che),只須再(zai)對(dui)糾(jiu)(jiu)偏(pian)(pian)(pian)(pian)裝(zhuang)置(zhi)(zhi)進行(xing)調整(zheng)(zheng)即可.值得注意(yi)(yi)的(de)(de)(de)(de)(de)(de)(de)是(shi),在上濾(lv)布(bu)(bu)之(zhi)前,要(yao)將所(suo)有的(de)(de)(de)(de)(de)(de)(de)濾(lv)布(bu)(bu)托(tuo)輥(gun)復查一(yi)遍,防止因運輸或是(shi)其他原(yuan)因造成的(de)(de)(de)(de)(de)(de)(de)濾(lv)布(bu)(bu)托(tuo)輥(gun)位(wei)移.保(bao)證濾(lv)布(bu)(bu)托(tuo)輥(gun)的(de)(de)(de)(de)(de)(de)(de)平行(xing)時很(hen)重要(yao)的(de)(de)(de)(de)(de)(de)(de).三、真(zhen)(zhen)空(kong)(kong)度偏低(di):出現這個(ge)問(wen)(wen)題(ti)(ti)時,在控制(zhi)室(shi)上可(ke)以看(kan)到,整個(ge)系統(tong)真(zhen)(zhen)空(kong)(kong)度低(di),脫水后的石膏濾餅(bing)含水量明顯偏高.出現這種(zhong)問(wen)(wen)題(ti)(ti)的主要(yao)原(yuan)因(yin)有(you)(you):一(yi)(yi)是(shi)真(zhen)(zhen)空(kong)(kong)室(shi)對接處(chu)脫膠.真(zhen)(zhen)空(kong)(kong)室(shi)一(yi)(yi)般由高分子(zi)聚合物(wu)制(zhi)造(zao)(zao),這種(zhong)材料(liao)伸(shen)縮變形很厲害,如(ru)(ru)(ru)果沒(mei)有(you)(you)及時固(gu)(gu)定(ding)或(huo)是(shi)沒(mei)有(you)(you)固(gu)(gu)定(ding)好(hao),那么就有(you)(you)可(ke)能造(zao)(zao)成脫膠.此種(zhong)情況下(xia),只有(you)(you)等停(ting)車(che)(che)(che)后,放下(xia)真(zhen)(zhen)空(kong)(kong)室(shi)重新補膠并(bing)固(gu)(gu)定(ding)每(mei)段真(zhen)(zhen)空(kong)(kong)室(shi).二是(shi)真(zhen)(zhen)空(kong)(kong)室(shi)下(xia)方法蘭連接處(chu)泄漏,這通常會有(you)(you)吹哨聲(sheng).解(jie)決這種(zhong)問(wen)(wen)題(ti)(ti)時,需要(yao)停(ting)車(che)(che)(che)后放下(xia)真(zhen)(zhen)空(kong)(kong)室(shi),檢查墊(dian)片(pian)情況,如(ru)(ru)(ru)果墊(dian)片(pian)有(you)(you)問(wen)(wen)題(ti)(ti)則(ze)更換墊(dian)片(pian),如(ru)(ru)(ru)果不是(shi)墊(dian)片(pian)問(wen)(wen)題(ti)(ti),那么只須將泄露(lu)(lu)處(chu)的法蘭螺(luo)栓(shuan)擰緊(jin)即可(ke).三是(shi)濾液(ye)總管泄露(lu)(lu),只須擰緊(jin)泄露(lu)(lu)處(chu)的螺(luo)栓(shuan),如(ru)(ru)(ru)果是(shi)墊(dian)片(pian)有(you)(you)問(wen)(wen)題(ti)(ti)則(ze)需要(yao)停(ting)車(che)(che)(che)后更換墊(dian)片(pian).預防真(zhen)(zhen)空(kong)(kong)泄露(lu)(lu),需要(yao)在系統(tong)安裝好(hao)后、濾布安裝前(qian)進(jin)行真(zhen)(zhen)空(kong)(kong)度測試.這樣可(ke)以把問(wen)(wen)題(ti)(ti)控制(zhi)在開車(che)(che)(che)之前(qian),避免(mian)開車(che)(che)(che)后的麻(ma)煩.
以上,就是(shi)關于皮(pi)帶脫水機(ji)出現問題(ti)后如(ru)何判(pan)斷(duan)故(gu)障和排修的(de)一些(xie)妙招,不知道是(shi)不是(shi)能夠幫助到大家(jia),然后大家(jia)對此還有什么(me)好的(de)建(jian)議或(huo)者意見,歡(huan)迎(ying)大家(jia)留言(yan).
