石英砂過濾器
石(shi)英(ying)砂過濾器屬于機械過濾器的(de)一種，又被稱為(wei)壓力式過濾器，簡稱為(wei)：砂濾器。采用ABS蘑菇型(xing)(xing)水(shui)帽或用(yong)球冠型(xing)(xing)多孔板配石(shi)英砂墊層(ceng)級配布水(shui)，內(nei)裝若(ruo)干(gan)種規格精制石(shi)英砂濾(lv)(lv)(lv)(lv)料，阻(zu)力(li)小，通量(liang)大。利用(yong)過(guo)濾(lv)(lv)(lv)(lv)器(qi)內(nei)所(suo)裝的填料來截留(liu)去除水(shui)中懸(xuan)浮微粒和膠(jiao)體雜質。當過(guo)濾(lv)(lv)(lv)(lv)器(qi)因濾(lv)(lv)(lv)(lv)層(ceng)污臟(zang)，出入口壓(ya)差(cha)增(zeng)大時，可(ke)用(yong)水(shui)（或水(shui)+壓(ya)縮(suo)空氣）反(fan)沖洗，使(shi)濾(lv)(lv)(lv)(lv)層(ceng)重新具有截獲懸(xuan)浮物的能力(li)。石(shi)英砂過(guo)濾(lv)(lv)(lv)(lv)器(qi)按控(kong)制類型(xing)(xing)可(ke)分為手動(dong)(dong)型(xing)(xing)和全自(zi)動(dong)(dong)型(xing)(xing)。手動(dong)(dong)型(xing)(xing)主要(yao)是通過(guo)閥門(men)的調節(jie)來控(kong)制過(guo)濾(lv)(lv)(lv)(lv)器(qi)的運行(xing)、正(zheng)洗、反(fan)洗；而(er)全自(zi)動(dong)(dong)型(xing)(xing)是通過(guo)自(zi)動(dong)(dong)過(guo)濾(lv)(lv)(lv)(lv)型(xing)(xing)控(kong)制器(qi)來進行(xing)對過(guo)濾(lv)(lv)(lv)(lv)器(qi)運行(xing)，正(zheng)洗、反(fan)洗等狀態的控(kong)制，按罐體材質可(ke)分為玻璃鋼(gang)罐、碳鋼(gang)罐、不銹鋼(gang)罐，罐內(nei)壁可(ke)根據(ju)用(yong)戶要(yao)求做內(nei)涂環氧涂層(ceng)或襯(chen)膠(jiao)防腐。
