一、管道屏蔽電泵的由來(lái)
屏蔽電泵開始出現(xiàn)和發(fā)展于二次世界大戰(zhàn)后,1952年美國(guó)化工泵公司研制了世界上*臺(tái)工業(yè)用管道屏蔽電泵,可以*無(wú)泄漏,雖然價(jià)格昂貴,但已得到廣泛應(yīng)用和發(fā)展。20世紀(jì)60年代,歐洲市場(chǎng)出現(xiàn)了小型管道屏蔽電泵,大大改進(jìn)了當(dāng)時(shí)的加熱系統(tǒng),節(jié)省了大量的配管裝置,回收了大量的熱能,為工業(yè)、民用的熱水循環(huán)提供了現(xiàn)代化裝置。英國(guó)屏蔽電動(dòng)機(jī)有限公司經(jīng)過(guò)長(zhǎng)期的研究,制成了結(jié)構(gòu)緊湊,符合現(xiàn)代化、微型化的各種工業(yè)和民用循環(huán)。20世紀(jì)70年代,丹麥格蘭富公司( Grundfos)的暖水循環(huán)電泵在歐洲市場(chǎng)上躍然,并在世界各地建立了子公司,他們的成功之處在于發(fā)展了的新工藝、新材料,提高了標(biāo)準(zhǔn)化程度。中國(guó)在20世紀(jì)50年代從美國(guó)引進(jìn)了的技術(shù)并應(yīng)用于原子能工業(yè)、石油化工工業(yè)和采暖設(shè)施等,雖然生產(chǎn)初期銷售量很低,但經(jīng)過(guò)半個(gè)多世紀(jì)的發(fā)展,目前我們已成為*制造的公司。

三、的概述
對(duì)于各類離心泵來(lái)說(shuō),填料密封、機(jī)械密封不可避免地存在軸封的泄漏問(wèn)題。原子能工業(yè)、石油化工工業(yè)等輸送高溫高壓液體、放射性液體、有毒有害液體、易燃易爆液體等特殊介質(zhì),不允許被輸送液體的點(diǎn)滴泄漏,否則將危害到人和設(shè)備的安全。在這種特定的要求下,開發(fā)了無(wú)泄漏泵(Non一leakage Pump)或稱之為無(wú)軸封泵( Nonseal Pump or Sealless Pump),也有人稱之為無(wú)填料泵( Clandless Pump),我國(guó)習(xí)慣性稱之為屏蔽電泵,是一種技術(shù)發(fā)展zui為成熟的無(wú)泄露泵。由于應(yīng)用工程的技術(shù)要求不同,輸送的介質(zhì)各異,所以無(wú)泄漏泵的種類也就多種多樣,以滿足生產(chǎn)中安全、可靠、經(jīng)濟(jì)等綜合要求。

以上只是部分性能參數(shù),如需查看詳細(xì)性能參數(shù)可以查看我公司的立式屏蔽泵產(chǎn)品。
屏蔽泵主要分為:臥式屏蔽泵和立式屏蔽泵兩種系列。
目前屏蔽電泵耐腐蝕材質(zhì)還只制作各類不銹鋼材質(zhì)的屏蔽電泵,如果需要用氟塑料材質(zhì)制作而成的無(wú)泄露泵我們建議選用氟塑料磁力泵系列更合適。
