Abstract

本实用新型涉及一种离心泵，包括泵体、装配在泵体中的叶轮及泵体后侧的后座，泵体上设有进液口和出液口，泵体内衬聚四氟乙烯层，叶轮外衬聚四氟乙烯层。本实用新型克服了现有的离心泵耐腐蚀性差、适用范围较窄、使用寿命短的缺陷，通过衬聚四氟乙烯层的具体设计，大大增强了离心泵的耐腐蚀性能，具有结构简单、适用范围广、使用寿命长的优点。

Description

离心泵
本实用新型涉及一种离心泵。
离心泵是一种用于输送液体介质的专用设备，不仅在民用领域如城市给排水、高层建筑增压送水、园林喷灌、消防增压、远距离输送和暖通制冷循环中具有重要作用，同时适用于石油、化工、冶金、电力、造纸、食品制药和合成纤维等工业部门。它一般由泵体、装配在泵体中的叶轮及泵体后侧的后座构成，泵体上设有进液口和出液口。这种普通的离心泵，由于其泵体和叶轮缺乏有效的防护，因此并不适合输送一些腐蚀性较强的介质，使其适用范围受到一定的限制。
本实用新型的目的是解决现有的离心泵耐腐蚀性差、适用范围较窄、使用寿命短的问题。本实用新型包括泵体、装配在泵体中的叶轮及泵体后侧的后座，泵体上设有进液口和出液口，泵体和后座的内侧壁上衬聚四氟乙烯层。
叶轮外衬聚四氟乙烯层。
本实用新型通过上述具体设计，大大增强了离心泵的耐腐蚀性能，具有结构简单、适用范围广、使用寿命长的优点。
以下结合附图和实施例说明本实用新型的详细内容。
附图是本实用新型的结构示意图。
如图所示，本实用新型包括泵体1、装配在泵体1中的叶轮2及泵体1后侧的后座3，泵体1上设有进液口4和出液口5，在泵体1和后座3的内侧壁上衬聚四氟乙烯层6，在叶轮2外衬聚四氟乙烯层7。在使用状态下，从进液口4端进入的介质液体在高速旋转叶轮的离心力作用下获得了能量提高压强，并从出液口5端输出。
