进口化工屏蔽泵(美国进口品Pai)
产品描述:
屏蔽泵是由屏蔽电动机和泵组成一体的无泄漏泵,主要由泵体、叶轮、定子、转子、前后轴承及推力盘等零部件组成。定子和转子分别用非磁性耐腐蚀薄壁套隔离起来,转子由前后轴承支撑浸在输送介质中,因而不需要任何型式的动密封来防止被输送介质的向外泄漏。 屏蔽泵是离心式无密封泵。这点与磁力泵相同。
屏蔽泵JD无泄漏,在泵内负压情况下,外界气体不会被吸入,特别适用于真空系统运行;同时它适用于高压、高熔点、高低温介质。屏蔽泵结构紧凑,体积小,重量轻;无冷却风扇、噪声较低,使用范围广,运转可靠,能提供一个相对良好的工作环境。屏蔽泵环保安全,非常适合输送易燃、易爆、易挥发、有毒、有腐蚀以及贵重液体,在化工、石化、医药等行业有广泛的用途。
磁力泵
尽管屏蔽泵的初始成本比较高,但由于其运行可靠,使用寿命较长,维护工作量少,因而其经济性并不低于其它类型泵;成本预算及后期维修等问题,用户也可以根据实际需要选择合适磁力泵。
屏蔽泵的工作原理
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。 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。
屏蔽泵的型式及适用范围
根据输送液体的温度、压力、粘度和有无颗粒等情况,屏蔽泵可分为以下几种:
1、基本型:输送介质温度不超过120℃,扬程不超过150m。其它各种类型的屏蔽泵都可以在基本型的基础上,经过变型和改进而得到 。
2、高压型: 高压型屏蔽泵的外壳是一个高压容器,使泵能承受很高的系统压力。为了支承处于内部高压下的屏蔽套,可以将定子线圈用来承受压力 。
3、逆循环型:在此型屏蔽泵中,对轴承润滑、冷却和对电机冷却的液体流动方向与基本型正好相反。其主要特点是不易产生汽蚀,特别适用于易汽化液体的输送,如液化石油气、一氯甲烷等。
4、高温型:一般输送介质温度350℃,流量高300m3/h,扬程高115m,适用于热介质油和热水等高温液体。
5、高熔点型:泵和电机带夹套,可大幅度提高电机的耐热性。适用于高熔点液体,温度高可达250℃。夹套中可通入蒸汽或一定温度的液体,防止高熔点液体产生结晶。
6、多级型: 装有复数叶轮,适用于高扬程流体输送,高扬程可达400m。
7、泥浆型:适用于输送混入大量泥浆的液体。
8、自吸型: 吸入管内未充满液体时,泵通过自动抽气作用排液,适应于从地下容器中抽提液体 。

We will think carefully about buildings and create thinking buildings
Arcadia commercial building services (CBS) relies on the concept of in-depth thinking of buildings. Our mission is to constantly think about and re-examine the building, so as to help customers to solve the big and small challenges. Therefore, we need to provide consulting engineers around the world with tools that can make their work faster and easier. Every day, consulting engineers can easily access our network tools and blueprint to obtain product priority information and pump related knowledge.
Be ready for the challenges of the future
The commercial construction industry is facing a series of challenges that will redefine the way we think about architecture in the next few years.
At the macro level, global climate change calls on all of us to take action to change the current situation. This means that buildings must adhere to strict sustainable development standards to maintain low energy consumption and high flexibility. At the micro level, consulting engineers are faced with the problem of many projects and insufficient supervision time. Therefore, it is very important to get correct information quickly and conveniently.
Excellent partner when thinking about buildings
Thinking about architecture also means that we see ourselves not only as suppliers of pumps, but also as partners in creating successful buildings. At the same time, it also means that we try to create buildings with in-depth pump and system knowledge as well as excellent intelligent pumps.
