Maintenance

We designed the machine evaluator with a comprehensive range of functions and the ability to select specific features to suit your particular needs. Using intuitive menus, functions are selected via the keypad or the touch screen. The fast processor and expanded memory enhance data logging. Measurement routes are easily downloaded from the PC to the instrument. You receive immediate, evaluated condition readings as measurement results

Green for good, red for bad, yellow for early warning. High-tech, yet easy to use.

are displayed on a green-yellow-red condition scale. This enables you to quickly investigate the cause of a reading in the red or yellow zone.

Technical solutions for a variety of operating conditions

The backbone of all predictive maintenance is up-to-date data on machine status, obtained with two well-tested frontline techniques to identify problem areas. Shock-pulse monitoring provides early detection of bearing damage and marginal lubrication conditions. Overall vibration severity monitoring, according to ISO standards, detects common mechanical faults such as imbalance, misalignment and loose parts.

Vibration severity

The machine evaluator measures overall vibration velocity, acceleration and displacement according to ISO 10816 standards, with menu selection of all specified machine classes and their alarm limits on a green-yellow-red scale. Historical trends are available both on the instrument and in the software.

Vibration analysis

With vibration analysis, you can diagnose machine problems such as imbalance, misalignment, and bearing and gear damage. The vibration time waveform is recorded and summarized by nine statistical parameters, including crest factor, kurtosis and skewness. FFT analysis produces a 12,800-line spectrum up to 40,000 Hz with true zoom and enveloping. The resulting FFT spectrum can be overlaid with machine-specific fault frequencies both in the instrument and the software.

Shock-pulse analysis for bearing evaluation

The shock-pulse method is a reliable and proven technique for monitoring ball- and roller-type bearings. It provides accurate information on the mechanical health and

lubrication condition within the bearing. The measurement results are displayed numerically and on a green-yellow-red scale for immediate evaluation of the bearing and lubrication condition.

Shock-pulse spectrum

Shock-pulse spectrum is a high-frequency technique for performing a detailed analysis of the bearing condition. A time record of the signal from a shock pulse transducer is subjected to an FFT analysis. This provides a spectrum that is compared with the rotational frequencies of the bearing components. In addition, it can analyze other periodic shock sources, such as gear damage.

Orbit analysis

For all machines with journal bearings, simultaneous measurement with two vibration transducers supplies an accurate graph of the shaft center line movement.

Structural resonances

Run up/Coast down measurement and bump test are tools for root cause analysis. They show the machine frame vibration characteristics, resonance frequencies and the reaction at critical speeds.

RFID tags

As labor-saving devices, RF identification tags can store measurement point data and the latest measurement results. The machine evaluator is programmed by reading tags via radio transponders.

A poorly aligned or out-of-balance machine wastes energy and causes premature failure. The machine evaluator is a state-of-the-art maintenance tool for fast and easy alignment and balancing.

Laser shaft alignment Machine evaluator uses a special line laser technique for the alignment of both horizontal and vertical machines. The LineLazerTM kit contains detector units and fixtures.

For easy and accurate targeting, the detector units send horizontally spread laser beams against large vertical receptors. Only one connecting cable to the instrument is needed. The laser beam is coded to guard against interference from other light sources. Automatic precision inclinometers constantly measure the angular shaft position. Three measurements over a shaft rotation angle well below 180 degrees determine present alignment. The graphical interface guides the user through the alignment process.

Dynamic balancing With the machine evaluator, single- and dual-plane rotor balancing in accordance with modern standard methods are easy operations. One can apply the traditional four-run technique or the two-run method with time synchronous measurement triggered by a tachometer connected to the instrument.

The machine evaluator supporting functions make it easy and reliable to conduct field balancing. It saves an influence matrix, which allows fast re-balancing calculations without stopping the machine to attach a test weight. An initial vibration measurement with spectrum analysis clearly show the existence and extent of imbalance, and thus the need and probable success of a balancing operation. The machine evaluator calculates the suitable trial weight and suggests a number of alternatives for correcting the imbalance. Correction mass, with the trial weight removed or remaining in place, can be radially displaced and split between two of the rotor partitions. For weight removal, drill hole diameter and depth for various materials are given. Weight position is displayed as the angle or distance measured along the rotor circumference. All trial weights on the rotor can be replaced by one final weight. For all methods, a final run can be made to check the balancing results and, if needed, a data file can be saved for future references.

Condmaster®Nova Software (supplied with ME-I and ME-II)

Condmaster®Nova

Condmaster®Nova software platform is designed to be used in conjunction with the machine evaluator to provide an efficient condition monitoring solution. With Condmaster®Nova software you can obtain practical solutions for condition diagnosis suited to your environment and applications.

Your primary tool for fast fault detection is the graphical overview, which identifies potential trouble spots.

The software accepts data from most Timken handheld and online condition monitoring systems. The software's modular design allows it to be fitted to your selected hardware. It supports preventive maintenance activities, such as time planning, trend graphics, statistics and reports. The system interacts with other maintenance software. Alarms via email and text messages can be configured.

Click on a point to view the details: measurement results, graphical trends, comments and more.

Condmaster®Nova contains an extensive bearing catalog and evaluation models for shock pulse, vibration and lubrication condition. Preprogrammed fault frequencies assist in pinpointing machine fault signatures in spectrum graphs.

Alarm lists are generated on the basis of automatically applied evaluation rules that can be modified by customer-defined thresholds.

Green-yellow-red coding at every surveillance level, from plant to individual measuring point, supplies a fast overview of all monitored equipment.

The FFT Spectrum can be overlayed with machinespecific vibration fault frequencies.

Condition monitoring requires an investment in personnel, instrumentation and training. You can start with a standard machine evaluator set and add functionality as your needs and experience grow.

Machine Evaluator I Set

The ME-I set consists of a data-logging instrument to measure speed, temperature, shock pulse and overall RMS vibration. It communicates with Condmaster®Nova software and also accepts manual data input. Individual functions may be added to the instrument to best meet your particular requirements. You can buy upgrade functions with the initial purchase or in the future in the form of an update file. Purchasing upgrades in the future would allow you to expand slowly as you gain experience and grow your reliability program.

Machine Evaluator II Set

The ME-II set has all the same features as the ME-I with the addition of advanced vibration analysis functions that include time wave form, FFT spectrum and fault symptom analysis.
