管道屏蔽电泵
一、管道屏蔽电泵的由来
屏蔽电泵开始出现和发展于二次世界大战后,1952年美国化工泵公司研制了世界上*台工业用管道屏蔽电泵,可以完全无泄漏,虽然价格昂贵,但已得到广泛应用和发展。20世纪60年代,欧洲市场出现了小型管道屏蔽电泵,大大改进了当时的加热系统,节省了大量的配管装置,回收了大量的热能,为工业、民用的热水循环提供了现代化装置。英国屏蔽电动机有限公司经过长期的研究,制成了结构紧凑,符合现代化、微型化的各种工业和民用循环。20世纪70年代,丹麦格兰富公司( Grundfos)的暖水循环电泵在欧洲市场上跃然,并在世界各地建立了子公司,他们的成功之处在于发展了的新工艺、新材料,提高了标准化程度。中国在20世纪50年代从美国引进了的技术并应用于原子能工业、石油化工工业和采暖设施等,虽然生产初期销售量很低,但经过半个多世纪的发展,目前我们已成为*制造的公司。

三、的概述
对于各类离心泵来说,填料密封、机械密封不可避免地存在轴封的泄漏问题。原子能工业、石油化工工业等输送高温高压液体、放射性液体、有毒有害液体、易燃易爆液体等特殊介质,不允许被输送液体的点滴泄漏,否则将危害到人和设备的安全。在这种特定的要求下,开发了无泄漏泵(Non一leakage Pump)或称之为无轴封泵( Nonseal Pump or Sealless Pump),也有人称之为无填料泵( Clandless Pump),我国习惯性称之为屏蔽电泵,是一种技术发展zui为成熟的无泄露泵。由于应用工程的技术要求不同,输送的介质各异,所以无泄漏泵的种类也就多种多样,以满足生产中安全、可靠、经济等综合要求。

以上只是部分性能参数,如需查看详细性能参数可以查看我公司的立式屏蔽泵产品。
屏蔽泵主要分为:卧式屏蔽泵和立式屏蔽泵两种系列。
目前屏蔽电泵耐腐蚀材质还只制作各类不锈钢材质的屏蔽电泵,如果需要用氟塑料材质制作而成的无泄露泵我们建议选用氟塑料磁力泵系列更合适。
