Preventive maintenance prevents unnecessary machine downtime and excessive wear on machine parts. This minimizes the risk of unplanned, often high repair costs. You therefore prevent machine failure by cleverly and regularly checking and maintaining your machine (or having it maintained).
ELMA’s range of preventive checks
Preventive inspections are the most important part of preventive maintenance. They identify wear and imbalance at an early stage, thereby preventing future malfunctions. It is essential that these inspections are carried out systematically and professionally. That is why Elma Services offers preventive maintenance and periodic inspections, performed by highly qualified service technicians.
Elma service engineers will assess your machine or setup for installation technical qualities. Our experts accurately map the results of a visual inspection. They check all motors, gearboxes, and pumps and describe their status in an inventory list. This is followed, if desired, by a suitable action or maintenance plan.
With the help of thermography, poor contacts and connections in control cabinets are detected. Hotspots in bearings and cabling of electric motors and generators also become visible. Damage and fire due to overheating are now prevented. You know exactly if and which corrections need to be implemented.
With an alignment check, you prevent malfunctions and wear to bearings, mechanical seals, couplings, and gears through adequate alignment control. Poorly aligned machines guarantee malfunctions. Elma Services alignment checks keep your machines in top condition.
The ideal machine produces no vibrations: all energy is utilized for the task for which the machine was designed. The reality, however, is different. Every machine will eventually start to vibrate due to wear. These vibrations, in turn, cause wear to other parts. And this leads to other defects. A chain reaction.
As long as the forces exerted are constant, or remain within certain limits, the measured vibrations will form a constant. A machine in good condition has its own typical vibration pattern. The frequency spectrum shows this typical and characteristic vibration pattern. This is obtained by analyzing the vibration signal in frequencies. When defects begin to develop within a machine, the dynamic processes change. This also shifts the forces exerted on certain parts. It is therefore not surprising that the level and pattern of vibrations also change.
Vibration signals contain a lot of information about the condition of a rotating machine. Elma Services maps this information by performing vibration analyses. The collected measurement results are processed into a professional report. Based on this, the service engineer makes the necessary recommendations.
