一、ZWB型自吸式防爆排污泵产品概述：
ZWB型自吸式防爆排污泵集自吸和无堵塞排污于一身，既可象一般清水自吸泵那样不需按底阀，不需引灌水、又可抽吸含有大颗粒固体块、长纤维的污物、沉淀物废矿杂质、粪便处理及一切工程污水物，配合防爆电机即可在一些特殊环境下工作。完全减轻工人的劳动强度，大大提高安全系数，而且使用、移动、安装方便、极少维修、性能稳定。
二、ZWB型自吸式防爆排污泵使用范围：
①环境温度≤45℃，介质温度≤60℃。
②介质PH值铸铁泵为6～9，不锈钢泵为1～14。
③通过颗粒最大直径为泵口径的60%，纤维长度为口径的5倍。
④介质中杂质总重量不超过介质总重量的15%，介质比重不超过1240千克/立方米。
三、ZWB型自吸式防爆排污泵结构及工作原理
ZWB型自吸式防爆排污泵主要由泵体、叶轮、后盖、机械密封、泵轴、轴承座、进口阀、气液分离管、加水阀门、进、排接管等组成。泵的结构见图。泵的工作原理：泵体内设有储液腔，并通过上方的回流孔和下方的循环孔与泵工作腔相通，构成泵的轴向回流外混式系统。泵停止工作后，泵内腔已储有一定容积的液体。当泵起动时，泵内的储液在叶轮的作用下，夹带着空气被向上抛出，液体通过气液分离管的网格回流到工作腔，气体被排出泵外，使泵内形成一定的真空度，达到自吸的作用。
