Vibration Analysis

The vibration analysis consists in determining the progressive and evident deterioration of rotating machinery through the taking of readings with portable or online equipment.

The vibration analysis services we offer are:

  • Vibration analysis based on periodic routes.
  • Studies to detect natural frequencies. (Impact tests)
  • Critical velocity detection through Bode graphs and Nyquist graphs
  • Orbital study with displacement sensors
  • Transmittance study with triaxial sensors.
  • Installation of fixed sensors and online monitoring.

The four basic steps in condition monitoring are:

  • Monitoring     
  • Analysis     
  • Correction     
  • Check.

Some problems that can be detected with vibration analysis:

  • Misalignment – Mechanical clearance – Gear problems
  • Bearing failure – Unbalance. – Pushups.
  • Cracks – friction – Lubrication problems. 
  • Problems in electric motors (stator and eccentric rotor)     
  • Power grinding problems in direct current motors.     
  • Resonances – Transmitted vibrations.     
  • Lack of rigidity in foundations, structures and supports.     
  • Vibration induced by flow. (cavitation, loosening in accessories)

Dynamic Balancing

Balancing is recommended primarily to improve the following aspects:

Increase the lifespan of:

Bearings, supports, housing and foundations that receive greater load and suffer greater wear due to poor balancing and consequently reduce their useful life.

Improve Security

High vibrations due to imbalance can loosen screws and nuts, until the machines are released. Switches and electrical connections can be damaged by vibrations. The imbalance can negatively influence the correct and safe operation and increases the danger to people and machines.

Quality

Working with a machine with high vibrations the result of what it produces will not have much precision and the efforts to produce are greater. An example is spindles or machine tools where vibrations negatively influence the result. A grinding machine or machine tool of high revolutions poorly balanced leaves the surface of poor quality or oval problems and produces more losses.

Effectiveness in the machines.

Smooth operation without noise will always be a sign of quality. In this way the imbalance can significantly lower your competitiveness. A vibrating appliance or a crankshaft of a car with high vibrations will not succeed in the market. Vibrations and annoying noises can be eliminated by balancing the rotating parts. In this way the distribution of its mass is improved, so that minor forces act on the supports

Laser alignment

The continuous increase of the speed of production, has increased the demand in the reliability of the machinery. Each manufacturing process requires that power be transmitted, whether to a pump, roller, impeller, etc. This force is usually transmitted by a motor which transmits the force of its axis to another axis.

The arrows must be assembled by some type of coupling, the purpose of the coupling is to minimize energy losses. When there is misalignment the axes will try to find a common axis of rotation, energy will be lost in the coupling and the loads on the machine components (seals, bearings, housings) will increase.

The laser alignment services we offer are:   

  • Alignment of Pulleys and Sprockets     
  • Alignment of axes.     
  • Machine train alignment     
  • Alignment of cardan arrows.     
  • Vertical axis alignment.     
  • Flatness check.     
  • Rail alignment (parallelism and leveling).     
  • Alignment of cranes wheels.     
  • Roller parallelism check.     

Leveling services Misalignment can manifest these 5 problems:     

  • Increase of vibration Misalignment. – Mechanical clearance – Gear problems     
  • Loss of energy.     
  • Increase in the loads of bearings, seals and other mechanical components.     
  • Reduce production capacity.     
  • Reduce production quality.

Geometric Measurements

Geometric measurement technology covers a wide range of applications. Among the measurements that can be performed by SCI are:

  • Straightness measurement of a component.     
  • Perpendicularity measurements of machine tools.     
  • Alignment in extruders.     
  • Verification of the centering of holes in boats.     
  • Hole centering check of power generating turbines.     
  • Roller Parallelism Verification

Easy-Laser® systems are excellent for performing all these types of measurements quickly and easily. Its universal and intelligent design offers many application possibilities, because laser transmitters and detectors are designed to be subjected to torsion, rotation and be installed in every possible way, and also the impossible ones!

Thermography

Thermographic Analysis is a professional diagnostic service offered by Reliability Solutions. The periodic evaluation of the operating conditions of the systems and equipment of the plant, through infrared thermography, has proven to be a very efficient tool that generates immediate results.

We can mention the following benefits of our service:     

  • Greater efficiency and availability of your assets.     
  • Decrease in unplanned shutdowns in electrical and mechanical machines and equipment.     
  • A better and more successful planning of your maintenance.     
  • Lower repair costs and consequently lower maintenance costs.     
  • Increase in the productivity of your processes.

Bearing Assembly and Disassembly Service

We have the tools and knowledge necessary to carry out disassembly and assembly of any type of bearings. The importance of having the right tools lies in not damaging the elements during handling and having the optimal life for which they were designed.

Among the tools that we have we have:     

  • Induction heaters.     
  • Hydraulic and mechanical extractors.     
  • Hydraulic pumps for extraction by oil injection method.

Bearing Failure Analysis

This service consists in determining the root cause of some bearing failure. The bearings will be cut and analyzed to determine the cause that caused the failure and thus correct the problem.

Some problems that can be observed with bearing failure analysis are:

  • Bad lubrication    
  • Bad mounting of the bearings.     
  • Current flow     
  • Contamination in the lubricant.     
  • Excessive adjustments     
  • Lack of load     
  • Misalignment     
  • Ovality in seats and accommodation

Lubricant Inspection

It is performed to the equipment that is lubricated with oil, this inspection will help us to observe the content of metal particles or contaminants that the equipment had to inspect and which give us evidence of the degree of deterioration of the machine and confirm the severity.

The inspection will be carried out by taking a sample between 30 and 50 mml of lubricant, passing it through a filter, to later be analyzed in a microscope and observe the content of particles that are present.

Bearing Selection and Engineering

Have you encountered the problem that your bearing supplier gives you a very long delivery time for a bearing that URGES you?.

Do not worry we can offer you a study of the application and propose a suitable bearing that is probably more easily found in the market.

Useful beyond the manufacturing environment

The SKF Microlog Inspector system is not limited to the manufacturing environment and can handle inspections related to planning, the environment, the Occupational Safety and Health Administration (OSHA) or other regulatory requirements or company interns.

The four basic steps in condition monitoring are:

Monitoring Analysis Correction Verification.

Some problems that can be detected with vibration analysis:

  • Misalignment – Mechanical clearance – Gear problems
