怎样选择过滤器

　在生产过(guo)(guo)程中，选(xuan)择好的过(guo)(guo)滤器(qi)以(yi)及(ji)怎样选(xuan)择过(guo)(guo)滤器(qi)至关重要，我们会根(gen)据(ju)您(nin)的设(she)备要求进行设(she)计，专门为您(nin)量(liang)身(shen)定做(zuo)。

3.1材(cai)质(zhi)(zhi)要精：前(qian)置过(guo)滤(lv)器(qi)的(de)滤(lv)网(wang)(wang)好(hao)(hao)不(bu)好(hao)(hao)，也决定了它的(de)品质(zhi)(zhi)好(hao)(hao)坏。有些前(qian)置过(guo)滤(lv)器(qi)用(yong)(yong)(yong)的(de)是尼龙滤(lv)网(wang)(wang)；有的(de)则是触(chu)感不(bu)佳的(de)不(bu)锈钢(gang)滤(lv)网(wang)(wang)（内部没(mei)有用(yong)(yong)(yong)来加固(gu)的(de)塑料结构）这样的(de)滤(lv)网(wang)(wang)容(rong)易变(bian)形，且不(bu)牢固(gu)、不(bu)耐用(yong)(yong)(yong)。建议消(xiao)费者应选购(gou)不(bu)容(rong)易生锈、变(bian)形的(de)过(guo)滤(lv)器(qi)材(cai)质(zhi)(zhi)产(chan)品，尤其采(cai)用(yong)(yong)(yong)食品级SUS316L不(bu)锈钢(gang)钢(gang)滤(lv)网(wang)(wang)为佳。铜主体材(cai)质(zhi)(zhi)优先考虑采(cai)用(yong)(yong)(yong)低铅(qian)铜材(cai)的(de)产(chan)品，避免使用(yong)(yong)(yong)劣质(zhi)(zhi)铜材(cai)长(zhang)期使用(yong)(yong)(yong)铅(qian)析出含量超(chao)标。

　3.2技术(shu)(shu)先进(jin)(jin)：前置(zhi)过(guo)滤(lv)(lv)器的(de)冲(chong)(chong)(chong)(chong)洗(xi)(xi)方式(shi)有直(zhi)冲(chong)(chong)(chong)(chong)和反(fan)冲(chong)(chong)(chong)(chong)两种，反(fan)冲(chong)(chong)(chong)(chong)的(de)技术(shu)(shu)更先进(jin)(jin)，市(shi)场占有优势。因为直(zhi)冲(chong)(chong)(chong)(chong)型在冲(chong)(chong)(chong)(chong)洗(xi)(xi)时(shi)，会用含有杂(za)质的(de)自来(lai)水(shui)从上往下冲(chong)(chong)(chong)(chong)洗(xi)(xi)，这样杂(za)质容(rong)易积留(liu)在滤(lv)(lv)网表层，而反(fan)冲(chong)(chong)(chong)(chong)技术(shu)(shu)可以用上层过(guo)滤(lv)(lv)后的(de)水(shui)进(jin)(jin)行(xing)反(fan)冲(chong)(chong)(chong)(chong)，并同时(shi)进(jin)(jin)行(xing)360度(du)自动旋转(zhuan)，这样滤(lv)(lv)网的(de)各个角度(du)都能冲(chong)(chong)(chong)(chong)洗(xi)(xi)到。另(ling)带滤(lv)(lv)网雨刮的(de)又比单纯反(fan)冲(chong)(chong)(chong)(chong)洗(xi)(xi)效果更好

　3.3过(guo)滤(lv)(lv)精(jing)度(du)(du)是指(zhi)过(guo)滤(lv)(lv)网(wang)的(de)孔径大小(xiao)(xiao)，尽量(liang)选择(ze)精(jing)度(du)(du)高(gao)(gao)也(ye)(ye)就(jiu)是数值小(xiao)(xiao)的(de)，但精(jing)密度(du)(du)越高(gao)(gao)的(de)产(chan)品，对滤(lv)(lv)网(wang)的(de)耐(nai)用性要求则更(geng)高(gao)(gao)，低于40微米(mi)较容易造成滤(lv)(lv)网(wang)堵塞，同时影(ying)响出水(shui)量(liang)。前置过(guo)滤(lv)(lv)器，过(guo)滤(lv)(lv)精(jing)度(du)(du)达(da)到40-50微米(mi)同时，出水(shui)量(liang)也(ye)(ye)可达(da)到3立方米(mi)/小(xiao)(xiao)时大流量(liang)。不仅能将(jiang)泥沙、水(shui)锈、红虫(chong)、大颗粒(li)有害物(wu)质(zhi)通通滤(lv)(lv)走，也(ye)(ye)能满足一般家庭用水(shui)量(liang)需求，不会出现“出水(shui)慢，水(shui)变小(xiao)(xiao)”等情况(kuang)。如果精(jing)度(du)(du)大于100μm的(de)过(guo)滤(lv)(lv)器效果就(jiu)比较差了，尽量(liang)不要选择(ze)。
