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(yi)(yi)、皮(pi)(pi)帶(dai)(dai)(dai)(dai)跑偏(pian):皮(pi)(pi)帶(dai)(dai)(dai)(dai)跑偏(pian)是(shi)真空皮(pi)(pi)帶(dai)(dai)(dai)(dai)機常見的(de)(de)問(wen)(wen)題(ti),也是(shi)難解決(jue)的(de)(de)問(wen)(wen)題(ti).為了(le)保(bao)護系(xi)(xi)統(tong),一(yi)(yi)般(ban)都會在(zai)皮(pi)(pi)帶(dai)(dai)(dai)(dai)兩邊設置皮(pi)(pi)帶(dai)(dai)(dai)(dai)跑偏(pian)的(de)(de)傳感器(qi).當(dang)(dang)皮(pi)(pi)帶(dai)(dai)(dai)(dai)跑偏(pian)后(hou),傳感器(qi)就(jiu)會發(fa)(fa)送信號到(dao)DCS,發(fa)(fa)出皮(pi)(pi)帶(dai)(dai)(dai)(dai)跑偏(pian)報警(jing)信號,皮(pi)(pi)帶(dai)(dai)(dai)(dai)逐漸(jian)偏(pian)離中(zhong)心(xin),真空度明(ming)顯上升(sheng)且濾餅含(han)水量(liang)(liang)增(zeng)大.當(dang)(dang)皮(pi)(pi)帶(dai)(dai)(dai)(dai)跑偏(pian)達到(dao)一(yi)(yi)定(ding)程度后(hou),出于(yu)保(bao)護系(xi)(xi)統(tong)的(de)(de)目的(de)(de),系(xi)(xi)統(tong)會自(zi)動(dong)(dong)(dong)緊急停(ting)車.皮(pi)(pi)帶(dai)(dai)(dai)(dai)跑偏(pian)一(yi)(yi)般(ban)是(shi)由于(yu)以(yi)下(xia)幾種(zhong)原(yuan)因(yin)造成:皮(pi)(pi)帶(dai)(dai)(dai)(dai)驅(qu)(qu)(qu)動(dong)(dong)(dong)輥(gun)和(he)皮(pi)(pi)帶(dai)(dai)(dai)(dai)張(zhang)(zhang)(zhang)緊輥(gun)的(de)(de)問(wen)(wen)題(ti).這(zhe)(zhe)可(ke)能有(you)兩個(ge)(ge)原(yuan)因(yin),一(yi)(yi)是(shi)皮(pi)(pi)帶(dai)(dai)(dai)(dai)驅(qu)(qu)(qu)動(dong)(dong)(dong)輥(gun)和(he)皮(pi)(pi)帶(dai)(dai)(dai)(dai)張(zhang)(zhang)(zhang)緊輥(gun)不平(ping)(ping)行(xing);二是(shi)皮(pi)(pi)帶(dai)(dai)(dai)(dai)張(zhang)(zhang)(zhang)緊輥(gun)和(he)皮(pi)(pi)帶(dai)(dai)(dai)(dai)驅(qu)(qu)(qu)動(dong)(dong)(dong)輥(gun)雖然平(ping)(ping)行(xing),但是(shi)卻沒有(you)對中(zhong),也即輥(gun)的(de)(de)軸線和(he)真空室不垂直(zhi).這(zhe)(zhe)個(ge)(ge)問(wen)(wen)題(ti)在(zai)工廠(chang)組裝的(de)(de)時(shi)(shi)候就(jiu)應該注意.如果是(shi)正在(zai)運行(xing)中(zhong),對于(yu)原(yuan)因(yin),則可(ke)以(yi)在(zai)停(ting)車后(hou)通過(guo)拉對角(jiao)線和(he)水平(ping)(ping)管或是(shi)水平(ping)(ping)儀來測(ce)定(ding)后(hou)調整,但要保(bao)證驅(qu)(qu)(qu)動(dong)(dong)(dong)輥(gun)的(de)(de)位(wei)置正確(que);對于(yu)第(di)二種(zhong)原(yuan)因(yin)則需要重新(xin)(xin)測(ce)量(liang)(liang)中(zhong)心(xin)點(dian),根據(ju)中(zhong)心(xin)點(dian)調整輥(gun)筒直(zhi)至(zhi)合(he)格.還有(you)一(yi)(yi)種(zhong)原(yuan)因(yin)是(shi)皮(pi)(pi)帶(dai)(dai)(dai)(dai)對接有(you)問(wen)(wen)題(ti).這(zhe)(zhe)是(shi)皮(pi)(pi)帶(dai)(dai)(dai)(dai)跑偏(pian)中(zhong)嚴重的(de)(de)問(wen)(wen)題(ti),主要有(you)斜接和(he)喇叭(ba)口(kou)兩種(zhong)問(wen)(wen)題(ti).出現這(zhe)(zhe)種(zhong)問(wen)(wen)題(ti),除了(le)更換(huan)新(xin)(xin)的(de)(de)皮(pi)(pi)帶(dai)(dai)(dai)(dai),無法采取其(qi)他的(de)(de)方法消除這(zhe)(zhe)個(ge)(ge)誤差.一(yi)(yi)般(ban)在(zai)皮(pi)(pi)帶(dai)(dai)(dai)(dai)對接時(shi)(shi),應該多選擇幾個(ge)(ge)點(dian)進行(xing)測(ce)量(liang)(liang),以(yi)保(bao)證皮(pi)(pi)帶(dai)(dai)(dai)(dai)對接正確(que).二、濾(lv)布(bu)跑偏(pian)(pian)(pian)(pian):濾(lv)布(bu)跑偏(pian)(pian)(pian)(pian)也是(shi)(shi)真(zhen)空皮帶機常見問題.一(yi)般的(de)皮帶機都會有濾(lv)布(bu)跑偏(pian)(pian)(pian)(pian)報警裝(zhuang)(zhuang)(zhuang)置(zhi),并(bing)有自動(dong)糾偏(pian)(pian)(pian)(pian)裝(zhuang)(zhuang)(zhuang)置(zhi).自動(dong)糾偏(pian)(pian)(pian)(pian)裝(zhuang)(zhuang)(zhuang)置(zhi)一(yi)般由電動(dong)或(huo)是(shi)(shi)氣(qi)(qi)(qi)(qi)動(dong)兩(liang)種方式(shi),啟動(dong)糾偏(pian)(pian)(pian)(pian)裝(zhuang)(zhuang)(zhuang)置(zhi)由傳感器(qi)(qi)、氣(qi)(qi)(qi)(qi)源分配器(qi)(qi)、調(diao)(diao)(diao)節(jie)氣(qi)(qi)(qi)(qi)囊(nang)組成.當濾(lv)布(bu)走(zou)偏(pian)(pian)(pian)(pian)時(shi)(shi)(shi),氣(qi)(qi)(qi)(qi)源分配器(qi)(qi)會根(gen)據濾(lv)布(bu)走(zou)偏(pian)(pian)(pian)(pian)的(de)方向(xiang)向(xiang)兩(liang)個調(diao)(diao)(diao)節(jie)氣(qi)(qi)(qi)(qi)囊(nang)分配壓縮空氣(qi)(qi)(qi)(qi),進而調(diao)(diao)(diao)節(jie)輥筒角度(du),達(da)到糾正濾(lv)布(bu)走(zou)向(xiang)的(de)作(zuo)用.一(yi)般情況(kuang)下,調(diao)(diao)(diao)整(zheng)好的(de)糾偏(pian)(pian)(pian)(pian)裝(zhuang)(zhuang)(zhuang)置(zhi)能夠保證(zheng)濾(lv)布(bu)自動(dong)糾偏(pian)(pian)(pian)(pian).這里要(yao)注(zhu)意的(de)是(shi)(shi),濾(lv)布(bu)在空轉(zhuan)、加(jia)水(shui)空負(fu)荷運(yun)轉(zhuan)轉(zhuan)和負(fu)荷運(yun)轉(zhuan)時(shi)(shi)(shi)均(jun)需調(diao)(diao)(diao)整(zheng)傳感器(qi)(qi)的(de)位置(zhi)和角度(du).如果只是(shi)(shi)在空轉(zhuan)或(huo)是(shi)(shi)加(jia)水(shui)空負(fu)荷運(yun)轉(zhuan)的(de)時(shi)(shi)(shi)候調(diao)(diao)(diao)整(zheng)糾偏(pian)(pian)(pian)(pian)裝(zhuang)(zhuang)(zhuang)置(zhi),就(jiu)會發生濾(lv)布(bu)跑偏(pian)(pian)(pian)(pian)現象,此時(shi)(shi)(shi)不須(xu)停車,只須(xu)再對糾偏(pian)(pian)(pian)(pian)裝(zhuang)(zhuang)(zhuang)置(zhi)進行調(diao)(diao)(diao)整(zheng)即可.值得注(zhu)意的(de)是(shi)(shi),在上濾(lv)布(bu)之(zhi)前,要(yao)將所有的(de)濾(lv)布(bu)托輥復查一(yi)遍,防止因運(yun)輸或(huo)是(shi)(shi)其(qi)他原因造(zao)成的(de)濾(lv)布(bu)托輥位移.保證(zheng)濾(lv)布(bu)托輥的(de)平行時(shi)(shi)(shi)很重(zhong)要(yao)的(de).三(san)、真(zhen)(zhen)(zhen)空(kong)度偏低(di):出現(xian)這(zhe)個問(wen)(wen)(wen)題(ti)(ti)(ti)時(shi),在控制室(shi)(shi)(shi)上可(ke)以看(kan)到,整個系(xi)統真(zhen)(zhen)(zhen)空(kong)度低(di),脫(tuo)水后(hou)(hou)的(de)(de)石(shi)膏濾(lv)餅含水量明顯偏高.出現(xian)這(zhe)種問(wen)(wen)(wen)題(ti)(ti)(ti)的(de)(de)主(zhu)要(yao)原(yuan)因有(you)(you):一是真(zhen)(zhen)(zhen)空(kong)室(shi)(shi)(shi)對接(jie)處(chu)脫(tuo)膠.真(zhen)(zhen)(zhen)空(kong)室(shi)(shi)(shi)一般(ban)由高分子聚(ju)合物制造,這(zhe)種材料伸(shen)縮變形很厲(li)害,如果(guo)沒有(you)(you)及時(shi)固(gu)定或是沒有(you)(you)固(gu)定好,那么就有(you)(you)可(ke)能造成(cheng)脫(tuo)膠.此種情(qing)況(kuang)下(xia),只(zhi)有(you)(you)等停(ting)車后(hou)(hou),放下(xia)真(zhen)(zhen)(zhen)空(kong)室(shi)(shi)(shi)重新補(bu)膠并(bing)固(gu)定每段真(zhen)(zhen)(zhen)空(kong)室(shi)(shi)(shi).二是真(zhen)(zhen)(zhen)空(kong)室(shi)(shi)(shi)下(xia)方法蘭連接(jie)處(chu)泄漏(lou),這(zhe)通常會有(you)(you)吹哨聲.解決這(zhe)種問(wen)(wen)(wen)題(ti)(ti)(ti)時(shi),需(xu)要(yao)停(ting)車后(hou)(hou)放下(xia)真(zhen)(zhen)(zhen)空(kong)室(shi)(shi)(shi),檢查(cha)墊片(pian)情(qing)況(kuang),如果(guo)墊片(pian)有(you)(you)問(wen)(wen)(wen)題(ti)(ti)(ti)則(ze)更換(huan)(huan)墊片(pian),如果(guo)不是墊片(pian)問(wen)(wen)(wen)題(ti)(ti)(ti),那么只(zhi)須將泄露處(chu)的(de)(de)法蘭螺栓擰緊即可(ke).三(san)是濾(lv)液總(zong)管泄露,只(zhi)須擰緊泄露處(chu)的(de)(de)螺栓,如果(guo)是墊片(pian)有(you)(you)問(wen)(wen)(wen)題(ti)(ti)(ti)則(ze)需(xu)要(yao)停(ting)車后(hou)(hou)更換(huan)(huan)墊片(pian).預防真(zhen)(zhen)(zhen)空(kong)泄露,需(xu)要(yao)在系(xi)統安(an)裝(zhuang)好后(hou)(hou)、濾(lv)布安(an)裝(zhuang)前(qian)(qian)進(jin)行真(zhen)(zhen)(zhen)空(kong)度測試.這(zhe)樣可(ke)以把(ba)問(wen)(wen)(wen)題(ti)(ti)(ti)控制在開車之前(qian)(qian),避免開車后(hou)(hou)的(de)(de)麻煩.
以上,就是關于皮帶脫水(shui)機出現問題后(hou)如何判斷故障和(he)排修的一些妙招,不知(zhi)道是不是能(neng)夠(gou)幫助到大(da)家,后(hou)大(da)家對(dui)此(ci)還有什么(me)好(hao)的建議或者意見,歡(huan)迎大(da)家留言.
