Vibro - thermo - tribo - diagnostic analysis and energy audits.

Every device vibrates. Each vibration is machine-specific, and this vibration changes from changing the conditions under which the machine operates. The noise that is emitted is only a partial information about the state of the machine. Vibration analysis helps you to detect a wide range of machine fault conditions. Increasing vibration may indicate normal component wear, or may indicate the origin of the problem, and may indicate the need for necessary maintenance intervention. Understanding vibration and its course is a key information for the following troubleshooting steps.
Thermal energy is always present when operating machines. It arises from the frictional movement of parts with each other, by electrical resistance, in the machining of materials, production, etc., resulting in energy losses.

When is vibration a problem?

VIBRODIAGNOSTICS is a non-dismantling method of diagnosing rotary machinery, which is a set of methods for obtaining vibration information. Using vibrodiagnostics, we can quite accurately determine the cause and location of a disorder. The vibrations are associated with the dynamic state of the equipment, technical condition, bearings, bearing condition, alignment, rotor parts unbalance, wear, loosening, and so on.

Vibration in machines can be characteristic or cause failure. Increased vibration should not be reflected in electric motors, pumps, compressors, fans and air conditioning. In these devices, smooth running is generally considered better, and devices operating at minimum vibration are ideal.

What Causes Vibration?

  • Increased energy consumption.
  • Increased repair and replacement cost.
  • Increased negative effects of the device on the working environment (noise, vibration, heat).
  • Increased component temperature due to malfunction.
  • Reduced bearing and component life.
  • Unexpected failures and downtime (reduced productivity)

Vibration Analysis Benefits.

  • Comprehensive overview of device status.
  • Possibility to anticipate component lifetime and thus possible downtime, repairs.
  • Accurate definition of the problem, the origin of the disorder.
  • Reduced vibration - increased lifetime, increased productivity, improved product quality.
  • Elimination of downtime.
  • Eliminate the source of vibration - a safe and quality work environment.
  • Reduced lubrication costs (reduced vibration - reduced temperature with wear - lower need for lubrication).
  • Environmental and economic aspect of predictive maintenance.

Instruments for vibrodiagnostics

 

We use top quality equipment for the diagnosis of ADASH and FIXTURLASER.

Why thermography as a service for you?

Thermodiagnostics can accurately, clearly and visibly show mechanical errors that are manifested by increased temperature. Non-contact temperature measurement is used: in industry, electrical engineering, construction, medicine, food, military, etc. We offer you thermodiagnostics with the help of a professional thermal imager that you can control:

  • Bearing overheating
  • belts
  • Conveyor belts
  • Temperatures of the processed material
  • Fasteners (clamps, couplings, ...) on power lines of virtually all voltage systems
  • Glands and shells including power transformer coolers
  • Check switches, switches.

Energy audits

The cooling channel test is important in liquid-cooled electrical machines. Avoid the risk of air trapped inside the cooling system or to create a fistula that gets caught in this type of audit in time and prevents damage.

 
        

Energetické audity uloženia ložísk.

Thermal imaging tests determine bearing overheating when mounted in electric motors and prevent damage.

This may be due to:

  • lubricants do not match
  • the lubricant level is too low or too high
  • bearing tight fit
  • uneven support surface
  • exhaustion of the seal
  • rotor unbalance
  • vibration and shaft currents

 

Energy audits of airflow.

This type of audit is used to assess the airflow through individual distribution elements and to find possible short circuits in the air flow.
So we can reduce the system's energy instability and prevent element damage.

 

Tribodiagnostic

TRIBOTECHNICAL DIAGNOSTICS is a non-dismantling method of technical diagnosis that uses lubricant as a medium to obtain information about changes in friction nodes. The results of the measurements are information about the state of foreign matter in the lubricant. In tribodiagnostics, we monitor the aging of the oil in service and assess the magnitude of the change in intensity and degree of oil degradation to change performance and hence the ability of the oil to ensure trouble-free operation.
