The diagram in Figure 3 shows one of the defects that may be introduced in plant operations during maintenance. identify and describe the various possible ways by which the defect shown in Figure 3 can be introduced in plant operations briefly discuss the possible consequences of the defect illustrated in Figure 3 as a reliability engineer what suggestions and procedures can you put in place to avoid accepting this type of defect?

Solution

This defect is known as misalignment.

It is not easy to detect misalignment on machinery that is running.

Using vibration analysis or infrared thermography, it is possible to identify primary symptoms of misalignment such as high vibration readings on radial and axial direction , abnormal temperature gradient in machine casing.

There are number of different methods whereby acceptable rotating machine alignment can be achieved .We can condense these methods into three catagory:
