一、ZW型无堵塞自吸式排污泵产品概述：ZW型无堵塞自吸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***、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，完全减轻工人的劳动强度，而且使用、移动、安装方便、***维修、性能稳定。二、ZW型系列无堵塞自吸式排污泵使用范围：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***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、ZW型系列无堵塞自吸式排污泵结构及工作原理ZW型无堵塞自吸泵主要由泵体、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。四、ZW自吸无堵塞排污泵型号参数：型号口径（mm）流量扬程功率吸程转速进口出口(m3/h)(m)(KW)(m)(r/min)ZW25-8-1525258151.55.52900ZW25-8-30252583035.52900ZW32-5-2032325202.25.52900ZW32-10-20323210202.25.52900ZW32-9-30323293035.52900ZW40-10-20404010202.25.52900ZW40-20-15404020152.25.52900ZW40-15-304040153035.52900ZW50-10-20505010202.25.52900ZW50-20-12505020122.25.52900ZW50-15-305050153035.52900ZW50-18-205050182035.52900ZW50-20-35505020355.55.52900ZW50-25-30505025305.55.52900ZW50-20-40505020407.55.52900ZW50-20-5050502050115.52900ZW65-30-186565301845.52900ZW65-30-186565301845.51450ZW65-25-30656525305.55.52900ZW65-25-40656525407.55.52900ZW65-40-25656540257.55.51450ZW65-50-30656550307.55.52900ZW65-65-25656565257.55.52900ZW65-25-5065652550115.52900ZW80-40-168065401645.02900ZW80-40-168065401645.01450ZW80-50-20806550205.55.01450ZW80-40-25806540257.55.51450ZW80-25-40806525407.55.52900ZW80-65-25806565257.55.52900ZW80-80-20806580357.55.51450ZW80-80-3580658035155.52900ZW80-40-508065405018.55.51450ZW80-50-6080655060225.02900ZW100-100-1510080100157.55.51450ZW100-80-201008080207.55.51450ZW100-100-201008010020115.51450ZW100-100-301008010030225.51450ZW100-80-45100808045305.52900ZW100-80-60100808060375.52900ZW100-80-80100808080455.52900ZW125-120-2012512512020155.51450ZW150-180-1415012518014155.51450ZW150-150-2015012515020155.51450ZW150-200-151501252001518.55.51450ZW150-200-2015012520020225.51450ZW150-180-2015012518020225.01450ZW150-160-3015012516030305.01450ZW150-180-3015012518030375.01450ZW150-180-3815012518038555.51450ZW150-150-4515012515045555.51450ZW200-280-1420015028014225.01450ZW200-280-2020015028020375.01450ZW200-300-2520015030025455.01450ZW200-280-2820015028028555.21450ZW250-420-2025020042020554.51450ZW300-800-1430025080014554.51450)
