夹套式磁力泵在苯酐装置中的应用

水泵原理 卧泉泵业 871浏览 0评论

YI、QIANYAN

苯酐,全称邻苯二甲酸酐,是重要的有机化工原料之一,广泛的用作增塑剂、树脂、医药、染料及农药等的原料和中间体。常温下,苯酐结晶为片状白色固体,熔点131.6℃。苯酐工业生产采用的是邻二甲苯的气相催化氧化法,它是在易燃、易爆、高温、有毒等条磁力泵件进行的,氧化温度高达440℃,液体苯酐的精制温度也高达180-250℃。生产过程中,若液态苯酐溅到皮肤上,除烫伤外,它还易吸水生成具有强腐蚀性的邻苯二甲酸;气态苯酐,具有强烈的刺激性,吸入后,咳嗽、咽喉疼痛、粘膜充血、眼睛红肿流泪等对人体危害很大,在明火条件下还可导致燃烧爆炸等严重事故。因此,苯酐装置的设备技术要求很高,关键设备多为进口。比如苯酐泵,国内装置一般选择德国KSB公司、美国DURCO公司等的产品,全为夹套式机械密封离心泵皇冠即时比分。但由于苯酐物化特性的原因,该类型机泵密封寿命短,维护费用高,而且在设备维修过程中,苯酐对人体和环境的危害都很大。

三、夹套式磁力泵的优点

选用静密封机泵替代动密封的离心泵,首先考虑屏蔽泵,它是一种常用的无密封式机泵,但是存在高温介质对屏蔽电机运行的不利和初次开车前无法判断滑动轴承处有无不熔固体介质的困难,故不适合输送高熔点苯酐产品的要求。相对磁力驱动的无密封泵却能满足以上条件。
