管道過(guo)濾(lv)器是管道輸送(song)液體過(guo)程中清除(chu)固體雜(za)質的設(she)備(bei)(bei)。液體流經過(guo)濾(lv)器時，其中的雜(za)質被濾(lv)出(chu)，可保護機(ji)泵、壓(ya)縮(suo)機(ji)、儀表和其它設(she)備(bei)(bei)正(zheng)常工作。當需(xu)要(yao)(yao)清洗時，只要(yao)(yao)將可拆卸的濾(lv)筒取出(chu)，去除(chu)濾(lv)出(chu)的雜(za)質后，重新裝入即可，使用維護極(ji)為方便。
1.手動控制:
將手動/自動選(xuan)擇(ze)開關(guan)旋(xuan)轉(zhuan)至手動位置(zhi)，見圖8，電機和水力控制(zhi)閥(fa)接通電源，水力控制(zhi)閥(fa)打開，開始排污。選(xuan)擇(ze)開關(guan)旋(xuan)轉(zhuan)至自動位置(zhi)，進入自動狀態。
手(shou)動(dong)控(kong)制(zhi)狀(zhuang)態(tai)是檢(jian)查電機和水(shui)力(li)控(kong)制(zhi)閥能否正常工作(zuo)的手(shou)段，如(ru)果在(zai)手(shou)動(dong)控(kong)制(zhi)狀(zhuang)態(tai)不能正常排(pai)污自動(dong)控(kong)制(zhi)狀(zhuang)態(tai)也不會正常工作(zuo)。
2.自動控制:
將手動/自動選擇開關旋(xuan)轉至自動位置，首先設定過濾時(shi)間和排(pai)污時(shi)間定時(shi)器。定時(shi)器的下排(pai)數碼管(guan)顯示設定值，上排(pai)數碼管(guan)顯示計時(shi)值。
定時(shi)(shi)器(qi)設定方(fang)法(fa):按一(yi)下位選鍵，下排一(yi)個(ge)數碼管閃爍(shuo)(shuo)，用增(zeng)加(jia)鍵調(diao)整數值(zhi)，調(diao)整好再按一(yi)下位選鍵，第二個(ge)數碼管閃爍(shuo)(shuo)，用增(zeng)加(jia)鍵調(diao)整數值(zhi)，依次(ci)(ci)類推(tui)。設定好時(shi)(shi)間(jian)，數碼管繼續(xu)閃爍(shuo)(shuo)8秒，8秒后(hou)數值(zhi)存入(ru)內(nei)存，且掉(diao)電不丟(diu)失。調(diao)整好數值(zhi)后(hou)，按一(yi)下啟(qi)動(dong)(dong)鍵，開始計時(shi)(shi)。如果機器(qi)斷電，下一(yi)次(ci)(ci)上電，定時(shi)(shi)器(qi)自(zi)動(dong)(dong)啟(qi)動(dong)(dong)，按照設定時(shi)(shi)間(jian)進行計時(shi)(shi)。
過(guo)濾(lv)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)以分(fen)為(wei)單位，大到9999分(fen)鐘(zhong);排(pai)(pai)污(wu)(wu)(wu)(wu)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)以秒為(wei)單位，大時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)到99.99秒。機(ji)(ji)(ji)器上電，用(yong)選擇開(kai)(kai)(kai)關進(jin)(jin)入(ru)自動(dong)狀態，首先進(jin)(jin)行過(guo)濾(lv)，過(guo)濾(lv)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)定時(shi)(shi)(shi)(shi)(shi)(shi)(shi)器開(kai)(kai)(kai)始(shi)計(ji)(ji)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)，同時(shi)(shi)(shi)(shi)(shi)(shi)(shi)壓差(cha)開(kai)(kai)(kai)關也將實際(ji)壓差(cha)與設(she)定壓差(cha)進(jin)(jin)行比較(jiao)，如(ru)果(guo)設(she)定的(de)過(guo)濾(lv)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)到了(le)，而(er)壓差(cha)沒有到，機(ji)(ji)(ji)器也打(da)開(kai)(kai)(kai)排(pai)(pai)污(wu)(wu)(wu)(wu)閥進(jin)(jin)行清(qing)洗(xi)排(pai)(pai)污(wu)(wu)(wu)(wu)，過(guo)濾(lv)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)停(ting)(ting)(ting)止(zhi)(zhi)計(ji)(ji)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)，排(pai)(pai)污(wu)(wu)(wu)(wu)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)開(kai)(kai)(kai)始(shi)計(ji)(ji)時(shi)(shi)(shi)(shi)(shi)(shi)(shi);當(dang)排(pai)(pai)污(wu)(wu)(wu)(wu)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)到，關閉(bi)排(pai)(pai)污(wu)(wu)(wu)(wu)閥，停(ting)(ting)(ting)止(zhi)(zhi)清(qing)洗(xi)排(pai)(pai)污(wu)(wu)(wu)(wu)，排(pai)(pai)污(wu)(wu)(wu)(wu)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)停(ting)(ting)(ting)止(zhi)(zhi)計(ji)(ji)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)，過(guo)濾(lv)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)開(kai)(kai)(kai)始(shi)計(ji)(ji)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)，進(jin)(jin)入(ru)下(xia)一(yi)個(ge)循環(huan)(huan)，如(ru)果(guo)設(she)定的(de)過(guo)濾(lv)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)沒到，而(er)壓差(cha)到了(le)，機(ji)(ji)(ji)器打(da)開(kai)(kai)(kai)排(pai)(pai)污(wu)(wu)(wu)(wu)閥進(jin)(jin)行清(qing)洗(xi)排(pai)(pai)污(wu)(wu)(wu)(wu)，過(guo)濾(lv)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)停(ting)(ting)(ting)止(zhi)(zhi)計(ji)(ji)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)，排(pai)(pai)污(wu)(wu)(wu)(wu)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)開(kai)(kai)(kai)始(shi)計(ji)(ji)時(shi)(shi)(shi)(shi)(shi)(shi)(shi);當(dang)排(pai)(pai)污(wu)(wu)(wu)(wu)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)到，關閉(bi)排(pai)(pai)污(wu)(wu)(wu)(wu)閥，停(ting)(ting)(ting)止(zhi)(zhi)清(qing)洗(xi)排(pai)(pai)污(wu)(wu)(wu)(wu)，排(pai)(pai)污(wu)(wu)(wu)(wu)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)停(ting)(ting)(ting)止(zhi)(zhi)計(ji)(ji)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)，過(guo)濾(lv)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)(jian)開(kai)(kai)(kai)始(shi)計(ji)(ji)時(shi)(shi)(shi)(shi)(shi)(shi)(shi)，如(ru)此(ci)循環(huan)(huan)往復。
