混流泵

首页 > 产品 > 混流泵

详细说明:

产品概述: HW型泵为卧式、单级、单吸、涡壳式混流泵。

适用于输送清水或物理、化学性质类似于水的其它液体。

被输送的液体温度不宜高于50℃。

广泛用于农田排灌、工业和城市给排水等多种场合。

型号意义: 以300HW-8A为例

300——泵进、出口直径(mm)

HW——卧式涡壳混流泵

8——设计扬程(m)

A——切割叶轮外径或换用不同性能的叶轮。

性能范围: 流量:70~6500m3/h

扬程:4~20m

口径:150~900mm

结构特点: 1、HW型泵主要由泵盖、叶轮、泵体、泵轴、轴套及轴承体(口径≤350mm)或轴承架(口径≥400mm)等主要零件构成。

2、泵盖分别与泵体和进水管相接。泵盖平面与叶轮平面之间应有适当间隙。间隙过小会产生摩擦;间隙过大,会导致泵体内的压力水大量回流、使泵的效率降低。实际使用的适宜间隙为0.3-0.7mm(将泵轴推向泵的进口端),间隙可用增减纸垫厚度来调整。

3、轴封装置由填料、填料压盖、填料环和泵体上的调料函组成(150HW和200HW型泵无填料环)。其作用是防止空气吸入泵内和防止水从泵内过多地沿轴流出。
