(1)启动前的准备工作
①检查轴承箱内润滑油脂，加注太多反而因搅拌而发热。若润滑油不足时应予补足。 ②检查地脚螺栓等固定连接件有无松动，电机接地是否良好。
③盘泵，检查泵轴是否转动灵活，有无零部件相互摩擦的声响。
④打开泵壳和吸入管路高点的放气阀，利用吸入罐液位静水压力自流灌泵，或用真空泵引油灌泵，确认泵壳和吸入管路中没有气体后关闭放气阀。
⑤关闭泵的出口阀门，准备启动。
(2)启动启动电机，待排出管路上的压力表达到额定值并稳定后慢慢打开泵的出口阀，调整到所需工况。泵的空转时间不宜太长，“以免密封环干摩擦生热，—般以不超过1～2min 为宜。
(3)运行离心泵稳定运行后要随时观察泵的真空表、压力表和电气系统的电流表，如果出现异常应及时对其原因作出判断，并采取相应措施。如不见效，应停泵做进一步检查。同时，要注意观测轴封的泄漏情况，监听运转是否平稳，有无不正常的声音。
(4)泵的切换其操作步骤是，按泵的启动方法启动备用泵，缓慢打开备用泵出口阀，并保持短时间两台泵并联运行，待运转平稳后缓慢关闭第一台泵的出口阀，然后停泵。泵的切换操作中，阀门的开启或关闭都不能太快，以免引起水击。
(5)停泵先缓慢关闭出口阀，然后切断电源，再关闭进口阀；待泵体温度下降到室温后，关闭冷却水和封液阀门；最后做好运行记录。
装配顺序
1、转子组装
(1) 叶轮应装在轴的正确位置上，不能偏向一侧，否则会造成与泵壳的轴向间隙不均而产生摩擦。
(2) 装上轴套并拧紧轴套螺母。为防止水顺轴漏出，在轴套与螺母间要用密封胶圈填塞。组装后应保证胶圈被轴套螺母压紧且螺母与轴套已靠紧。
(3) 将密封环、填料套、水封环、填料压盖及挡水圈装在轴上。
(4) 装上轴承端盖和轴承，拧紧轴承螺母，然后装上轴承体并将轴承体和轴承端盖紧固。
(5) 装上联轴器。
2、吊入转子
(1) 将前述装好的转子组件平稳地吊入泵体内。
(2) 将密封环就位后，盘动转子，观察密封环有无摩擦，应调整密封环直到盘动转子轻快为止。
3、扣泵盖
将泵盖扣上后，紧固泵结合面螺栓及两侧的轴承体压盖。然后，盘动转子看是否与以前有所不同，若没有明显异常，即可将空气管、密封水管等连接上，把填料加好，接着，就可以进行对联轴器找正了。
3、单吸双吸离心泵安装精度
这里给出的主要是联轴器对中的精度要求。泵与电机联轴器装好后，其间应保持2～3mm间隙，两联轴器的外圆上下、左右的偏差不得超过0.1mm，两联轴器端面间隙的最大、最小值差值不得超过0.08mm。

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.
