屏蔽泵的性能特点及选型随着化学工业的发展以及人们对环境、安全意识的提高，对化工用泵的要求也越来越高，在一些场合对某些泵提出了绝对无泄漏要求，这种需求促进了屏蔽泵技术的发展。屏蔽泵由于没有转轴密封，可以做到绝对无泄漏，因而在化工装置中的使用已愈来愈普遍。 1 屏蔽泵的原理和结构特点 普通离心泵的驱动是通过联轴器将泵的叶轮轴与电动轴相连接，使叶轮与电动机一起旋转而工作，而屏蔽泵是一种无密封泵，泵和驱动电机都被密封在一个被泵送介质充满的压力容器内，此压力容器只有静密封，并由一个电线组来提供旋转磁场并驱动转子。这种结构取消了传统离心泵具有的旋转轴密封装置，故能做到完全无泄漏。 屏蔽泵把泵和电机连在一起，电动机的转子和泵的叶轮固定在同一根轴上，利用屏蔽套将电机的转子和定子隔开，转子在被输送的介质中运转，其动力通过定子磁场传给转子。 此外，屏蔽泵的制造并不复杂，其液力端可以按照离心泵通常采用的结构型式和有关的标准规范来设计、制造。 2 屏蔽泵的优缺点 2.1 屏蔽泵的优点 (1)全封闭。结构上没有动密封，只有在泵的外壳处有静密封，因此可以做到完全无泄漏，特别适合输送易燃、易爆、贵重液体和有毒、腐蚀性及放射性液体。 (2)安全性高。转子和定子各有一个屏蔽套使电机转子和定子不与物料接触，即使屏蔽套破裂，也不会产生外泄漏的危险。 (3)结构紧凑占地少。泵与电机系一整体，拆装不需找正中心。对底座和基础要求低，且日常维修工作量少，维修费用低。 (4)运转平稳，噪声低，不需加润滑油。由于无滚动轴承和电动机风扇，故不需加润滑油，且噪声低。 (5)使用范围广。对高温、高压、低温、高熔点等各种工况均能满足要求。 2.2 屏蔽泵的缺点 (1)由于屏蔽泵采用滑动轴承，且用被输送的介质来润滑，故润滑性差的介质不宜采用屏蔽泵输送。一般地适合于屏蔽泵介质的粘度为0.1～20mPa.s。 (2)屏蔽泵的效率通常低于单端面机械密封离心泵，而与双端面机械密封离心泵大致相当。
