What is a Compound Move and When do I use it to Benefit the Alignment Process?

September 29, 2015

A “Compound Move” is when an aligner performs both a vertical correction by shimming and a horizontal correction by moving a MTBM (movable machine) simultaneously.

Traditionally, during the alignment process, after a rough alignment is made, the aligner will shim the movable machine until it is within the vertical alignment tolerance. Once within vertical tolerance, the aligner will then make the horizontal correction. Sometimes this will result in several moves until the tolerance is reached for both vertical and horizontal.

The “Compound Move” has been used successfully by many aligners for 20+ years. The success of making a vertical and horizontal correction simultaneously is dependent on when to perform this step.

The following steps should be performed before making a Compound Move:

  1. All pre-alignment checks and corrections completed.
  2. Rough align the MTBM.
  3. Perform Rough (Initial) Soft Foot.
  4. Perform Final Soft Foot.
  5. Now, perform the Compound Move and you will find that many times, you will complete the final alignment in just one or two moves.

The benefit of performing a Compound Move is saving time.


How can you make your plant more profitable and stable?

September 22, 2015

Traditionally, company profits have been maintained and increased through three primary means:

  1. Increase the price of goods and services sold.
  2. Increase the amount of goods and services sold.
  3. Reduce the costs of goods and services sold.

Options 1 and 2 can be very difficult or even impossible to implement in a competitive market.  Therefore, option #3 may seem like the only viable option.  Reductions in costs can be accomplished in many ways.  Some are drastic attempts such as reducing product quality or the number of employees.  It is almost impossible for companies to achieve true long term profit gains in these ways, because those gains are usually short-lived.

What can you do to help your company increase profits in the competitive world we live in, and provide greater stability in your job? Reduce the costs of goods and services produced (option #2) in a way that you or your facility may not have previously considered. You can do this by:

  • Improving equipment reliability through implementing Condition Monitoring reliability practices (RCM, FMEA, RCFA, etc).
  • Ensuring the correct maintenance activities are planned, scheduled and completed on-time.
  • Ensuring that the correct spare parts inventory is available and kitted when the work is scheduled and executed.
  • Ensuring that value-added PM’s are created and completed on the equipment.
  • Ensuring that reliability based engineering is completed. Maintenance cannot overcome poor design and installation.
  • Ensuring operational activities that support maintenance and reliability are followed. Maintenance and Operations should work as partners and not competitors.
  • Supporting those in your facility that are working toward these efforts.
  • Making sure that the right work is being done on the right equipment. This requires prioritizing based on a thorough understanding of equipment criticality, understanding how and why your equipment can fail, what really needs to be done to keep it operational upon demand, etc.

All of the above efforts can help your facility reduce maintenance costs and the cost of goods and services produced. This could be the difference between being the leader in your market or watching your job, profit and company suffer.


Proper Alignment for Machines with More than Four Feet Configuration

September 15, 2015

If the machine to be moved has 6, 8 or more anchor bolts, caution needs to be applied when deciding how to shim the middle machine feet.

A method still used by many is to calculate the shimming for the inboard and outboard feet of the MTBM and shim accordingly. Then, use a feeler gauge to determine the amount of shims required to “fill in” under the middle feet. You tighten the inboard and outboard feet before making the shim correction to the middle feet. A common practice is to add a few mils of shim under the middle feet to compensate for any casing sag due to the weight of the machine. The problem with this method is deciding how many mils of shims to add when compensating for casing sag.

Some laser shaft alignment tools can calculate the middle feet shim requirement based on the distance from the front (or inboard) feet to the middle feet. This calculation is based on simple rise over run and assumes that the base is completely flat. Some criticize this method of letting the laser alignment system calculate the middle feet corrections. The argument is that on a normal machine configuration, the four feet nearest the bearings establish the reference plane. But when additional feet are introduced, you should not assume they are in the same exact plane. This is true and shows up as a soft foot condition. Therefore, when a proper Rough soft foot and Final soft foot is performed, the calculated middle feet corrections by the laser alignment system is preferred over just guessing how much to shim the middle machine feet.

How our VIBCONNECT RF Wireless Condition Monitoring System Detected a Broken Belt

September 8, 2015

A customer with a need to monitor machinery remotely and limited to a small budget invested in the VIBCONNECT RF system to keep their machines running. During a routine check of the data, it was noticed that a certain machine was in alarm. The OMNITREND software easily identified the machine that was in alarm by the red indicator (see Fig. 1).

Figure 1

Figure 1

The customer contacted LUDECA to assist in analyzing the issue. The frequency did not match any of the components given for this machine. The waveform data showed extremely high levels of vibration and indicated that something was seriously wrong with this machine (see Fig. 2).

Figure 2

Figure 2

It was suggested that the machine be visually inspected for any abnormalities, including a strobe for the visual inspection. The strobe was locked into the known frequences that were showing in alarm. The customer was able to identify that a broken belt was the cause of the high vibration levels (see Fig. 3).

New belts were installed and the pulleys properly aligned using the DotLine Laser pulley alignment tool to prevent future belt failures due to misaligned pulleys.

Thermal Growth Compensation with Alignment Targets

September 1, 2015

Thermal growth compensation has become fairly routine among laser aligners. For machines that run at high temperatures, most manufacturers will recommend a target to align to that compensates for the thermal growth that the machine is expected to undergo. That target only tells half of the story though. In many of the situations we see, once operating, there may be more horizontal movement than vertical, and both movements often far different from the specified amounts. These differences usually arise from sources such as pipe stress, foundation looseness, operating load variances and other factors.

To ensure perfect alignment under operating conditions, you can monitor the positional change of machines at your plant using the ROTALIGN ULTRA and Live Trend module. During your next shut down, mount the lasers to the machines and monitor the cool down. During the shutdown, align the machines using your newly discovered targets and even verify the accuracy by re-measuring the positional during start up and run up to final operating condition.
