排污泵设计及应用问题解决

时间:2018-03-24 作者:admin

 

一、前言

潜水排污泵腾讯欢乐捕鱼主要用于石油、化工、钢铁、冶金、电力、环保、市政及建筑等行业,用于输送带固体颗粒及各种长纤维的废水、城市生活污水和雨水,还包括原水的输送、水产养殖、灌溉等。配以特种材质,可用于有一定腐蚀性介质的场合。

潜水排污泵是一种泵与电动机连体,并同时潜入液下工作的泵类产品,与一般卧式泵或立式排污泵相比,具有结构紧凑、占地面积小;安装维护方便;不用灌引水直接起动水泵;振动噪声小、电动机温升低、对环境无污染等优点,越来越受到重视,使用范围也越来越广。水泵厂(i4calais.com)浅谈QW型潜水排污泵的设计及相关经验,为设计者提供参考。
