Shaft Alignment: Rim & Face Method | CD Industrial Group Inc.

When speaking of a pumping system, proper alignment of two different types is important: the alignment of the pump shaft and the drive shaft, and the alignment of the pump flanges with the connecting piping. The alignment of the pump shaft to the drive shaft of the motor, gear, or engine driving the pump is called shaft alignment. The alignment of the pump flanges to the connecting piping is called flange alignment. The shafts of the pump and drive unit must be closely aligned. Failure to achieve proper alignment, a condition referred to as misalignment, will result in increased pump vibration, decreased bearing life, and has the potential to cause mechanical seal leakage and issues with the coupling.

Frequently Asked Questions

Maximize the sweep distance of the face dial indicator for the geometry of the machine being aligned. Achieving sub-pixel accuracy with face alignment algorithms is a difficult task given the diversity of appearance in real world facial profiles. Face alignment - the problem of automatically locating detailed facial landmarks across different subjects, illuminations, and viewpoints - is critical to face analysis applications, such as identification, facial expression analysis, robot-human interaction, affective computing, and multimedia. Several approaches process on 2D texture image but most of them perform decently only with small pose variation. Two methods will be covered: straight edge alignment, and rim and face alignment. Corrects improper face alignment. Robert Frischholz.


Figure 1. Corrects improper face alignment. A high-temperature deg F refinery pump may have a spool-piece coupling to accommodate thermal movement, and would require an operational assessment of target values. Fixture Mounting Precautions.
