March 02, 2006 Alignment Tip
PIPE STRAIN
When performing an alignment on a new pump installation, check to make sure that pipe stress acting on the pump is within reasonable amounts.
To check for this, take a set of zero-reference readings with your laser alignment system, and start the move function, monitoring both the vertical and horizontal planes simultaneously. Slowly unbolt the piping and check to make sure that no more than .002” movement occurs at the shaft. In addition, the retightening can be monitored, to establish the repeatability of the pipe strain. If movement greater than .002” is observed, the piping must be modified to take care of this problem.

March 02, 2006 Electrical Safety Tip
Always double check your circuit voltage tester before and after using it prior to working on anything electrical, to make sure it is de-energized. Remember, a non-working tester says its dead and then you might be for not double checking the tester!

March 02, 2006 Motor Testing Tip
Electric motor winding shorts develop over time. According to studies developed by D.E. Crawford of General Electric, the most common fault is the breakdown of insulation between conductors that result from movement of the coils during startup and under load. The wear and tear, coupled with other issues such as temperature, contamination, etc., cause the insulation system properties to change over time at random points within the insulation system, rarely the first few turns. The purpose of Motor Circuit Analysis is to evaluate the condition of the insulation system throughout the complete motor winding circuit with the ability to detect the changes in the insulation system indicating an impending winding short.
Developing winding shorts can be detected many months in advance of the actual winding short. This allows the ability for the company to utilize MCA to detect winding contamination and winding shorts with enough time to schedule repair or replacement without having a negative impact on production. The process involved in determining the availability of the motor over time is Time To Failure Estimation.

March 02, 2006 Belt Driven Equipment Tip
The two Achilles heals of belt driven equipment are sheave
alignment, and belt tension.
Dramatically increase performance with the following installation procedures.
1. Use taper-lock bushing type sheaves. Bushings with 3 bolts.
2. Use magnetic base dial indicator to dial axial runout to within .003”. Well within M.P.T.A. or R.M.A. specs.
3. Use a torque wrench to bring the sheave into spec.
4. Alignment-Yes these $1,000 lasers are very nice, but not
necessary. Forget the string, and forget the straight edge. Use (two) straight edges, one against the drive sheave face, and the other against the driven sheave face. It will instantly give you the parallel offset and the angularity! As far as the vertical, a torpedo level on each sheave will give satisfactory results. Use pre-cut shims to match the motor to the driven sheave.
5. Belt tension. Looser is better than tighter. Equipment run
across the line can expect belt squeal at startup. Equipment on variable frequency drives should ramp up smoother.
Remember if you double the radial load on the bearings, you get the inverse cube of the wear! That’s 1/8th the life.

March 02, 2006 Maintenance Tip
Treat your Maintenance organization as a 3-Legged Stool equal partnership among Operations, Stores and Maintenance. If any leg is not functioning properly, the job will fail.
Operations is still the customer but their role is to provide the “When”. Have the equipment ready when the mechanics arrive and don’t turn them away when they show up as scheduled.
The planner working with Stores handles the “What”. Have the parts, materials and resources available before starting the job.
The scheduler and Maintenance supervision provide the “Who”. Have the right person with the right skills to do each scheduled job. This must apply for all non-emergency work.
Establish a daily communication process to ensure that you get really good at predicting Today what you will do Tomorrow and stick to it. This must be a true team effort to develop the trusting relationships to allow each of us to prove that we will do what we say we will do. It requires changing old habits and getting back to the basics.
