静态指标术语

1、相数：产生不同对极N、S磁场的激磁线圈对数。常用m表示。

2、拍数：完成一个磁场周期性变化所需脉冲数或导电状态用n表示，或指步进电机转过一个齿距角所需脉冲数，以四相电机为例，有四相四拍运行方式即AB-BC-CD-DA-AB，四相八拍运行方式即 A-AB-B-BC-C-CD-D-DA-A。

今天为大家介绍一下旋转机械轴承振动和发热的原因分析及处理。旋转机械（特别是高速旋转机械）在运行过程中影响因素较多，比如：设备制造质量、使用正确与否、装配质量、润滑等。故障发生时，往往最直接的体现就是旋转机械设备振动发生了异常变化。某公司两台11MW机组各配两台Y4—73No.28F（右旋45°/135°）型引风机，叶轮回转体（机械侧）用滚动轴承支撑并承载转动，轴承润滑采用浸油润滑方式，冷却采用油室加设环绕冷却水的方式。

由于阀门的用途是广泛的，因此它起的作用也是很大的。：在发电厂中阀门能够控制锅炉和汽轮机的运转；在石油、化工生产中，阀门同样也起着控制全部生产设备和工艺流程的正常运转。在其它部门也是这样。尽管如此，阀门同其它产品比较往往被人们忽视。：在安装机器设备时，人们往往把重点放在主要机器设备方面，如：压缩机、高压容器、锅炉等；也有的选用不当。这些作法都会使整个生产效率降低或停产、或造成种种其它事故发生。
