进口循环管道泵-进口品牌哪个好
选型：
1、循环管道泵的总流量不应小于管网总设计流量，当热水锅炉出口至循环管道泵的吸入口装有旁通管时，应计入流经旁通管的流量。
2、循环管道泵的流量-扬程特性曲线，在水泵工作点附近应比较平缓，以便在网路水力工况发生变化时，循环管道泵的扬程变化较小。一般单级水泵特性曲线比较平缓，宜选用单级水泵作为循环管道泵用。
3、循环管道泵的承压、耐温能力应与热网的设计参数相适应。循环管道泵多安装在热网回水管上。循环管道泵允许的工作温度，一般不能低于80℃。如安装在热网供水管上，则必须采用耐高温的热水循环管道泵。
4、循环管道泵的工作点应在水泵高效工作范围内。
5、循环管道泵台数的确定，与热水供热系统采用的供热调节方式有关。循环管道泵的台数不得少于两台，其中一台备用。当四台或四台以上水泵并联运行时，可不设置备用水泵，采用集中质调节时，宜选用相同型号的水泵并联工作。
6、多热源联网运行或采用中央质量-流量调节的单热源供热系统，热源的循环管道泵应采用变频调速泵。
7、当热水供热系统采用分阶段改变流量的质调节时，各阶段的流量和扬程不同。为节约电能，宜选用流量和扬程不等的泵组。
8、对具有热水供应热负荷的热水供热系统，在非供暖期间网路流量远小于供暖期流量，可考虑增设专用热水负荷用的循环管道泵。
9、当多台水泵并联运行时，应绘制水泵和热网水力特性曲线，确定其工作点，进行水泵选择。

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)，从中获得产品优先资讯和泵的相关知识。
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。
如果您正在市场上寻找高度可靠的水处理解决方案，阿卡迪亚的专业知识可以满足您的每一种期望。作为完整的生产线供应商，我们涵盖了从供应、处理和分配的整个水循环过程，并确保了每一步都可以获得所需的确切水质。
阿卡迪亚提供的水处理解决方案专为优化复杂和要求苛刻的工业流程而定制，同时阿卡迪亚的专业支持一直就在您的身边。从而确保了您和您的客户可以轻松地获得当地语言的专业知识和技术支持。

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.
