反沖洗


五、工作原理

水由入口進(jìn)入,首先經(jīng)過(guò)粗濾網(wǎng)濾掉較大顆粒的雜質(zhì),然后到達(dá)細(xì)濾網(wǎng)。在過(guò)濾過(guò)程中,細(xì)濾網(wǎng)逐漸累積水中的臟物、雜質(zhì),形成過(guò)濾雜質(zhì)層,由雜質(zhì)層堆積在細(xì)濾網(wǎng)的內(nèi)側(cè),因此在細(xì)濾網(wǎng)的內(nèi)、外兩側(cè)就形成了一個(gè)壓差。

當(dāng)過(guò)濾器的壓差達(dá)到預(yù)設(shè)值時(shí),將開(kāi)始自動(dòng)清洗過(guò)程,此間凈水供應(yīng)不斷流,清洗閥打開(kāi),清洗室及吸污器內(nèi)水壓大幅度下降,通過(guò)濾筒與吸污管的壓力差,吸污管與清洗室之間通過(guò)吸嘴產(chǎn)生一個(gè)吸力,形成一個(gè)吸污過(guò)程。同時(shí),電力馬達(dá)帶動(dòng)吸污管沿軸向做螺旋運(yùn)動(dòng)。吸污器軸向運(yùn)動(dòng)與旋轉(zhuǎn)運(yùn)動(dòng)的結(jié)合將整個(gè)濾網(wǎng)內(nèi)表面完全清洗干凈。整個(gè)沖洗過(guò)程只需數(shù)十秒鐘。排污閥在清洗結(jié)束時(shí)關(guān)閉。過(guò)濾器開(kāi)始準(zhǔn)備下一個(gè)沖洗周期。

六、清洗特點(diǎn)

7、反沖洗過(guò)濾器設(shè)有就地控制,必要時(shí)可設(shè)遠(yuǎn)傳控制轉(zhuǎn)換開(kāi)關(guān),以實(shí)現(xiàn)就地操作和遠(yuǎn)控操作。

8、反沖洗過(guò)濾器留有運(yùn)行狀態(tài)輸出、故障報(bào)警輸出等功能,保證設(shè)備使用在可靠條件下全自動(dòng)反沖排污過(guò)濾器功能作用

反沖洗過(guò)濾器過(guò)濾能力強(qiáng),大流量:煤礦上大量使用的大流量直通式過(guò)濾器,由于結(jié)構(gòu)的限制,流量只能達(dá)到 380L/min,該過(guò)濾器可達(dá) 800L/min 或著更大。全自動(dòng)過(guò)濾器,過(guò)濾器,全程綜合水處理器,電子除垢器反沖洗過(guò)濾器過(guò)濾精度高:反沖洗過(guò)濾器內(nèi)有兩組或多組濾芯,通流面積大,原始?jí)毫p失小,可實(shí)現(xiàn)大流量、高精度過(guò)濾(25 m40 m,傳統(tǒng)過(guò)濾器則很難實(shí)現(xiàn)。反沖洗過(guò)濾器量化污染程度:該過(guò)濾器在液體的流入端 Pi 口、流出端 Po 口可裝有壓力表 K1K2,P=K1-K2 的壓差大小,定量的反應(yīng)了過(guò)濾器被污染的程度,便于隨時(shí)清洗,傳統(tǒng)過(guò)濾器則無(wú)次功能。
