I.
Application:
HW Spiral
Mixed-flow pump is a horizontal type, single stage, single suction and
cantilever spiral mixed flow pump, which is used for farmland irrigation and drainage,
industry, town water supply and drainage and water diversion of docks.


3、安装基础:要求土质坚实牢固。
4、水泵安装时,必须保证泵轴的水平位置。
5、进水管末端应浸入水平面以下一米左右,但须离开泥底半米左右。
6、水泵安装好后,计算允许吸上高度和扬程,在水位稳定的条件下,要求为规定数量值的0.8~1.2倍范围,否则水泵不会正常运行
Installation Principle
1. Installation
Height: Cidering the height according to the rainy season or dry season.The suction
vacuum
height can
not be higher than the adsorbing height.
2. Installation
Location:The location is better to close to the water source as p as
should be not
only
keeping the safety but also shortening the water inlet pipe and reduce the
headloss
轴流泵的工作原理及特点
1、轴流泵的工作原理
轴流泵与离心泵的工作原理不同,它主要是利用叶轮的高速旋转所产生的推力提水。轴流泵叶片旋转时对水所产生的升力,可把水从下方推到上方。
轴流泵的叶片一般浸没在被吸水源的水池中。由于叶轮高速旋转,在叶片产生的升力作用下,连续不断的将水向上推压,使水沿出水管流出。叶轮不断的旋转,水也就被连续压送到高处。
