结构：
泵的主要零件有泵体、泵盖、叶轮、轴、双吸密封环、轴承和轴承体等。泵体与泵盖为铸铁制成，共同构成叶轮的工作室，泵体进、出水法兰盘上有安装压力计和真空计的管螺孔，管径低处有的管螺孔。叶轮为双侧进水。其形状是对称的，出厂时经静平衡试验。轴承：本系列泵的结构分甲、乙两种形式，甲式的采用滚动轴承，用黄油润滑；乙式采用滑动轴承，用稀油润滑。靠近联轴器一端的通称轴承甲部件，另一端称轴承乙部件由于叶轮是对称的，其本身就平衡了轴向力，由于制造误差等产生的残余轴向力由轴承乙部件中的单列向心轴承平衡。甲式结构的轴承体部件是籍轴承体压盖固定在泵体上，由于该压盖是装配后与泵体同时镗孔，不具备互换性，所以压盖损坏后不能更换。轴封：泵的轴封由填料室、填料压盖、填料环、填料套、填料、轴套共同构成。泵盖内的少量高压水通过水封管及填料环流入填料室中。有些泵没有外装水封管，在泵盖的中开向上有预先铸出的两条沟槽，代替了外装水封管。填料的松紧程度，以液体能一滴一滴渗出为准。填料压得过紧，轴套易发热，轴套表面很快就被磨损。泵的传动是通过弹性联轴器由电动机驱动。从传动端看，泵为逆时针方向旋转
特性：
包括外壳结构和转子部件结构，所述外壳结构的中部形成共中心线的进水口和出水口，所述进水口和出水口相背设备；从所述中心线到所述离心泵的两端，所述外壳结构依次包括分别各自关于所述中心线对称的装有末级导叶的进出水段、装有导叶的导流中段、吸入泵盖和轴承体；所述转子部件结构包括主轴以及设置在所述主轴上的轴承、轴承挡套、轴套、正流道叶轮组、反流道叶轮组和叶轮衬套，所述正流道叶轮组和反流道叶轮组以叶轮衬套的中点对称布置；所述正流道叶轮组和反流道叶轮组都包括多个间隔设置的叶轮，所述叶轮、导叶和末级导叶共同形成多个相互连通的高压腔，连通后的高压腔一端与出水口相连通，另一端通过低压腔与进水口相连通。
优势：
轴向力和径向力完全平衡，无平衡水，通过双壳体的结构，进出水管线在同一条管线的中心线上，维修保养不需要拆卸管道，压力腔内置，提高了水泵运行的安全性，比同一种参数的水泵效率要提高5%以上；另外，流量是同样叶轮数的普通多级泵2倍，而压力只有一半。进水和出水在同一条中心线上，安装拆卸方便，压力腔内置，使用更安全，维修保养不需要拆卸进出水管道，十分方便。

我们会对建筑物进行审慎的思考，并藉此创造出懂得思考的建筑物
阿卡迪亚商用建筑服务(CBS)赖以生存的理念在于对建筑物的深入思考。我们的使命是不断对建筑进行思考和重新审视，从而帮助客户解决大大小小的挑战。所以，我们要为全球咨询工程师提供能够使其工作更迅速轻松的工具。每天咨询工程师可以轻松访问我们的网络工具和电子杂志蓝图(BLUEPRINT)，从中获得产品优先开云电子链接 和泵的相关知识。
准备好迎接未来的挑战
商用建筑行业面临着一系列的挑战，这些挑战将会重新定义未来数年我们对于建筑的思考方式。
宏观上看，全球气候变化呼吁我们每个人采取行动来改变现有状况。这意味着建筑物必须遵守严格的可持续发展标准以保持低能耗和高灵活性。微观处，咨询工程师们却面临着工程多，监理时间严重不足的难题。因此，快速方便地获取正确的信息显得尤为重要。
对建筑物进行思考时的优秀拍档
思考建筑也意味着我们不仅把自己当作泵的供应商，而且还视为创造成功建筑的合作伙伴。同时这还意味着我们尝试用深入的泵和系统知识以及优异的智能泵来创建建筑。

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.
