自动反冲洗过滤器
一、外形及结构直通式自动冲洗排污过滤器直角式自动冲洗排污过滤器二、自动冲洗排污原理直通式自动冲洗排污原理:直角式自动冲洗排污原理:1、工作过滤正常工作时,水流转向阀为开启状态。需处理的水通过过滤网后利用惯性原理而将水中的细小颗粒杂质及悬浮物由于惯性作用沉积在排污口附近。2、冲洗排污正常冲洗时,水流转向阀为开启状态。当滤网截留水中的细小颗粒杂质及悬浮物达到一定数量时,将排污口上的阀门打开,即由于水流的作用将粘在过滤器收集段部分的杂质冲质冲洗直到排出水清澈为止。再关闭排污口上的阀门进入正常工作状态。3、反冲洗排污反冲洗时,水流转向阀为关闭状态,排污阀开启,这时水流被迫从过滤网筒的入口段网孔进入过滤筒外侧与壳体夹层,反向从网筒外侧冲洗粘附在网孔上的杂质,达到清洁过滤网的目的。由于转向阀关闭,水经过反冲阀后流带增大,反洗效果好。三、技术参数壳体材质碳钢不锈钢滤框滤网材质不锈钢密封件材质耐油石棉、丁晴橡胶、聚四氟乙烯工作温度(℃)-30~380-80~450公称压力(MPa)0.6~5.0(150Lb~600Lb)过滤精度(目/in)10-300四、规格与型号ZPG-Ⅰ型(直通式)自动排污过滤器单位(mm)型号LABD排污口DNZPG-I-40245185639015ZPG-I-502551907010015ZPG-I-652701958312020ZPG-I-803202329614025ZPG-I-10035026012818032ZPG-I-12543832616220040ZPG-I-15052539018923050ZPG-I-20070052022028065ZPG-I-25087565025533080ZPG-I-3001050780294380100ZPG-I-3501200885331450125ZPG-I-40014001040377480150ZPG-I-45015501145420500150ZPG-I-50017001250462580150ZPG-I-60020001460537650200ZPG-I-70022801720607700200ZPG-I-80025001900685820200ZPG-I-90028002180785880200ZPG-I-100031202470860920250ZPG-I-110034502780915960250ZPG-I-1200370030009651040250ZPG-I-15004470365012201400250ZPG-L型(直角式)自动排污过滤器单位(mm)型号LABCD排污口DNZPG-L-40320170802269015*ZPG-L-503501859024410015*ZPG-L-6538020010027012020*ZPG-L-8044523012031014025*ZPG-L-10053626516036518032*ZPG-L-12562431519044020040ZPG-L-15072837522052023050ZPG-L-20088450026067028065ZPG-L-250112062531083033080ZPG-L-30013107503501000380100ZPG-L-35015148754101180450125ZPG-L-400173010004701350480150ZPG-L-450189611255101500500150ZPG-L-500208012505501680580150ZPG-L-600249015006502000650200ZPG-L-700268016006802150700200ZPG-L-800288017507002300820200ZPG-L-900315018508002480880200ZPG-L-1000337020009002675920250ZPG-L-11003610210010002900960250ZPG-L-120038502250110030501040250ZPG-L-150047002800120038001400250注:a)所有连接法兰尺寸按GB4216-84制造b)“*”号为螺纹连接c)可根据用户需要订制非标准流量的产品和工作压力更高的产品)
