1、定義：

過濾器(filter)是輸送介質管道上不可缺少的一種裝置，通常安裝在減壓閥、泄壓閥、定水位閥 ,方工過濾器其它設備的進口端設備。過濾器由筒體、不銹鋼濾網、排污部分、傳動裝置及電氣控制部分組成。待處理的水經過過濾器濾網的濾筒后，其雜質被阻擋，當需要清洗時，只要將可拆卸的濾筒取出，處理后重新裝入即可，因此，使用維護極為方便。

2、工作原理：

液體通過濾(lv)渣(zha)層和過濾(lv)介質必(bi)須(xu)克服阻力(li)，因此在過濾(lv)介質的(de)兩側必(bi)須(xu)有壓(ya)(ya)力(li)差，這是實現過濾(lv)的(de)推動力(li)。增大壓(ya)(ya)力(li)差可以(yi)加(jia)速(su)過濾(lv)，但(dan)受壓(ya)(ya)后變形的(de)顆(ke)粒(li)在大壓(ya)(ya)力(li)差時易(yi)堵塞(sai)過濾(lv)介質孔(kong)隙，過濾(lv)反而減(jian)慢(man)。

懸浮液過(guo)濾有濾渣層過(guo)濾、深層過(guo)濾和(he)篩(shai)濾 3種方式。

①濾(lv)渣(zha)層(ceng)過濾(lv)：過濾(lv)初期過濾(lv)介質(zhi)只能截留大的固體顆粒，小顆粒隨濾(lv)液穿過過濾(lv)介質(zhi)。在形成(cheng)初始濾(lv)渣(zha)層(ceng)后(hou)，濾(lv)渣(zha)層(ceng)對過濾(lv)起主要作(zuo)用(yong)，這時大、小顆粒均被截留，例如板框壓濾(lv)機的過濾(lv)。

②深層過濾：過濾介質較厚(hou)，懸浮液中含固體(ti)顆粒較少，且(qie)顆粒小(xiao)于過濾介質的孔道(dao)。過濾時，顆粒進入后(hou)被吸附在(zai)孔道(dao)內(nei)，例如多孔塑料管過濾器(qi)、砂濾器(qi)的過濾。

③篩濾(lv)(lv)：過(guo)(guo)(guo)濾(lv)(lv)截留的(de)固體顆粒(li)都大(da)于過(guo)(guo)(guo)濾(lv)(lv)介質的(de)孔隙，過(guo)(guo)(guo)濾(lv)(lv)介質內部不(bu)吸附固體顆粒(li)，例如轉筒式過(guo)(guo)(guo)濾(lv)(lv)篩濾(lv)(lv)去污水中的(de)粗粒(li)雜質。在實際的(de)過(guo)(guo)(guo)濾(lv)(lv)過(guo)(guo)(guo)程中，三種方式常(chang)常(chang)是同(tong)時或相繼出現(xian)。

3、性能特點(dian)：

1.高效(xiao)，精確過(guo)濾(lv)：特殊結構的(de)(de)(de)濾(lv)盤(pan)過(guo)濾(lv)技術，性能精確靈(ling)(ling)敏，確保只有(you)粒徑小于要求(qiu)的(de)(de)(de)顆粒才(cai)能進入系(xi)統，是最有(you)效(xiao)的(de)(de)(de)過(guo)濾(lv)系(xi)統;規(gui)格有(you)5μ、10μ、20μ、55μ、100μ、130μ、200μ等多(duo)種，用(yong)戶可(ke)根據用(yong)水要求(qiu)選擇不同精度的(de)(de)(de)過(guo)濾(lv)盤(pan)。系(xi)統流(liu)量可(ke)根據需要靈(ling)(ling)活調(diao)節。

2.標準(zhun)模塊化，節省占(zhan)(zhan)地:系統(tong)(tong)基于(yu)標準(zhun)盤(pan)式過濾(lv)單元，按模塊化設計(ji),用(yong)戶(hu)可(ke)(ke)按需(xu)取舍,靈(ling)(ling)活(huo)可(ke)(ke)變,互換(huan)性強。系統(tong)(tong)緊湊，占(zhan)(zhan)地極(ji)小，可(ke)(ke)靈(ling)(ling)活(huo)利用(yong)邊角空(kong)間進(jin)行(xing)安裝(zhuang)，如處理水量300m3/h左右的設備(bei)占(zhan)(zhan)地僅約6m2(一(yi)般水質，過濾(lv)等(deng)級100μ)。

3.全(quan)自動運(yun)行,連續(xu)出(chu)水：在(zai)過濾器組合(he)(he)中(zhong)的(de)各(ge)單(dan)元之間(jian)，反(fan)(fan)洗過程輪流(liu)交(jiao)替進行，工(gong)作(zuo)、反(fan)(fan)洗狀(zhuang)態之間(jian)自動切換，可(ke)(ke)確保連續(xu)出(chu)水;反(fan)(fan)洗耗水量極少，只占出(chu)水量的(de)0.5%;如配合(he)(he)空氣輔(fu)助反(fan)(fan)洗，自耗水更可(ke)(ke)降到0.2%以(yi)下(xia)。高速而徹(che)底的(de)反(fan)(fan)洗，只需數十秒(miao)即可(ke)(ke)完成

4.壽命長：新型塑料過濾元件堅固、無磨(mo)損(sun)、無腐蝕、極少結垢，經多年工業實用(yong)驗證，使(shi)用(yong)6~10年也(ye)沒有磨(mo)損(sun)，不(bu)會(hui)(hui)老化，過濾和反(fan)洗(xi)效果(guo)不(bu)會(hui)(hui)因使(shi)用(yong)時間而變差。

5.高質量，維(wei)護量少(shao)(shao):產(chan)品符(fu)合相應質量標準(zhun)，所有(you)產(chan)品在出(chu)廠前均經模擬工(gong)況檢(jian)(jian)測(ce)和試運轉，不需專(zhuan)用工(gong)具(ju),零部(bu)件很少(shao)(shao);易于使用,僅需定期檢(jian)(jian)查(cha)，幾(ji)乎(hu)不需日常維(wei)護。

4、主要分(fen)類：

過(guo)濾(lv)(lv)器(qi)按獲得過(guo)濾(lv)(lv)推動力(li)的方法(fa)不同，分為(wei)重(zhong)力(li)過(guo)濾(lv)(lv)器(qi)、真空(kong)過(guo)濾(lv)(lv)器(qi)和加壓過(guo)濾(lv)(lv)器(qi)三類(lei)。

重(zhong)力：

借助懸浮液(ye)的(de)重力和位差在過濾介質上形成(cheng)的(de)壓力作(zuo)(zuo)為(wei)過濾的(de)推動力，一般為(wei)間歇操作(zuo)(zuo)，如砂(sha)器(qi)。

真(zhen)空：

常用的加(jia)壓過(guo)濾(lv)是利用濾(lv)室容積變小或施加(jia)機械壓榨(zha)力進行過(guo)濾(lv)，濾(lv)渣含濕量較低，適用于固體顆粒濃(nong)度高的懸浮(fu)液(ye)(ye)。在帶(dai)式壓榨(zha)過(guo)濾(lv)器中(zhong)，經重(zhong)力或真空初(chu)步脫(tuo)液(ye)(ye)后的濕濾(lv)渣夾在兩(liang)條濾(lv)帶(dai)之間移(yi)動，再經輥子擠壓脫(tuo)液(ye)(ye)。螺旋(xuan)壓榨(zha)過(guo)濾(lv)機具有帶(dai)孔隙(xi)的圓筒(tong)，其中(zhong)有旋(xuan)轉的螺旋(xuan)，螺旋(xuan)槽深不等，物料(liao)由深槽端(duan)加(jia)入推向(xiang)淺槽端(duan)，濾(lv)室空間逐漸減小，物料(liao)受到壓榨(zha)，濾(lv)液(ye)(ye)由圓筒(tong)的孔隙(xi)排出,濾(lv)渣由小端(duan)排出。

5、選(xuan)型(xing)要素(su)：

1、進出口通(tong)徑：

原(yuan)則(ze)上(shang)過濾器的進出口通徑不應小于相(xiang)配套的泵的進口通徑，一般與進口管路口徑一致(zhi)。

2、公稱壓力：

按照過濾管路可能(neng)出現的最(zui)高壓力確定過濾器的壓力等級。

3、孔(kong)目(mu)數(shu)的(de)選擇(ze)：

主要(yao)(yao)考慮需(xu)攔截的雜(za)質粒徑，依據(ju)介質流程工藝要(yao)(yao)求而(er)定。各種規格絲(si)網可攔截的粒徑尺寸(cun)查下表“濾(lv)網規格”。

4、過濾器(qi)材(cai)質：

過濾器的(de)(de)材質(zhi)一般選擇與所連接(jie)的(de)(de)工藝管(guan)道材質(zhi)相(xiang)同，對于不(bu)同的(de)(de)服(fu)役條件可考慮(lv)選擇鑄(zhu)鐵(tie)、碳(tan)鋼(gang)、低合金(jin)鋼(gang)或不(bu)銹鋼(gang)材質(zhi)的(de)(de)過濾器。

5、過(guo)濾器阻力損失(shi)計算(suan)

水用過(guo)濾(lv)器(qi)，在一般計算額定流速下，壓力損(sun)失為0.52～1.2kpa

6、選型注意點：

選用濾油器時，要考慮下列幾點：

⑴過濾(lv)精(jing)度應滿(man)足預定要(yao)求(qiu)。

⑵能(neng)在(zai)較(jiao)長(chang)時間內(nei)保持足夠的通流能(neng)力。

⑶濾芯具有足夠(gou)的強度，不因液壓的作用而損壞。

⑷濾芯(xin)抗腐蝕性能好(hao)，能在規定的溫(wen)度下(xia)持久(jiu)地(di)工作。

⑸濾(lv)芯(xin)清洗或更換簡便(bian)。

因(yin)此，濾油(you)器應根據液壓(ya)(ya)系(xi)統的技(ji)術(shu)要(yao)求，按過濾精(jing)度、通流能力、工作壓(ya)(ya)力、油(you)液粘度、工作溫(wen)度等條件選定其型號。
