吸入管可用软管和硬管,管路的材料必须适用输送液体,软管壁必须有足够的刚度,以防止吸入管凹瘪;
吸入管尽可能保持短而直,少用弯管及附件,弯管应使用较大半径的弯管;
浸入集水坑的吸入管离坑壁的距离应大于管径的1.5倍。吸入管不得安装在水流(可能存 在□涡)附近,否则应在吸入管与水流间增设一挡板,距离1.5倍的管径;
同一个集水坑如有二根以上吸入管,则管与管之间的距离应大于3倍管径;
吸入管液下深度:吸入管浸入液下深度与吸入管内液体流速有关,见图1。
可以通过扩大吸入管径,降低进水流速来减小吸入管浸入液下深度。 通过安装标准异径接头来扩大吸入管径,垂直扩径采用同心异径接头,水平扩径采用偏心异径接头,扩大管径比推荐1.3?1.5倍管径。
倒灌状态即泵的进口有压力,该进口压不得大于50%最大允许工作压力。
泵如配置滤网,滤网的过流面积是吸入管过流面积的4 - 6倍,而且保证滤网的最大通过颗粒直径小于泵的最大通过颗粒直径。
