管道离心泵是一种常见的离心泵类型,常用于供输送清水及物理化学性质类似于清水的其他液体,广泛适用于能源、冶金、化工、纺织、造纸等行业。想要保障管道离心泵的长期正常使用需注意正确选择并安装管道离心泵,然后还要注意定期维护。

一、正确选择及安装管道离心泵

管道离心泵应该按照所输送的液体进行选择,并校核输送介质需要的性能,分析抽吸,排出条件,是间歇运行还是连续运行等。

安装时要注意管道离心泵的基础的尺寸,位置,标高应符合设计要求,地脚螺栓必须恰当和正确地固定在混凝土地基中,机器不应有缺件,损坏或锈蚀等情况;

安装时应该核对主要零件,轴密封件和垫片的材质;所有与泵体连接的管道,管件的安装以及润滑油管道的清洗要求应符合相关国家标准的规定。

二、定期维护管道离心泵

定期检查管道离心泵机械密封是否失效。因为管道离心泵停机主要是由机械密封的失效造成的,而机械密封失效的表现大都是泄漏。

其次就是密封元件失效最多的部位是动,静环的端面,离心泵机封动,静环端面出现龟裂是常见的失效现象。
