FAN and BLOWER REPAIR Services

 Electromechanex is highly skilled in the repairing, rebuilding, modifying and retrofitting of   existing fan equipment. We take the performance criteria from the existing system to produce   a fan that meets or exceeds the dimensional and performance requirements of the customer.   Fan assemblies can be quickly tested in the field or at our repair facility for a quick diagnosis of   air, sound and vibration problems. As with all repair services, Electromechanex offers turnkey   service including; removal, repair, installation, laser-alignment, and machine start-up testing.

1.0 Vibration Analysis

At some time during the life of a fan or blower, it is likely to experience high vibration levels. What’s behind this maintenance phenomenon? The cause may be an electromagnetic or mechanical imbalance, loose components, rubbing parts, bearing failure, or resonance.When a problem occurs, it is critical to quickly identify the source and take corrective action. Using EMX’ latest vibration analysis diagnostic techniques can save you money and downtime. EMX’ uses VibePro 7.3.5 which is a portable device, route-based instrument used for collecting vibration data on rotating machinery. It reduces collection, analysis and reporting time, compared with similar devices. This allows EMX to determine the severity of the stress level of bearing or gear wear on your equipment. The data is recorded from each machine and uploaded on the software, providing quick recognition of change in the vibration pattern, as an indicator of deterioration. Corrective actions are then taken.

2.0 Die Penetrant Test

With a fan running at such a high speed, a die penetrant test uses a die, sprayed on the fan blades to detect a crack. Our team can either repair or recommend the equipment be removed from operation due to safety issues. Repairs can be made, both in the Shop and in the Field.

3.0 Shaft Repair

By working with our machine shop to manufacture or repair a shaft used in a fan or blower, customers experience a cost savings since this is more affordable than purchasing from a factory. In many cases, we prefer to machine the parts ourselves using our In-House Machine Shop. Many fan parts such as shafts and seal sleeves, as well as bearing housings can be sleeved and finish machined in our own machine shop. Additionally some worn fan parts can be coated with a polymer composite that can be easily machined in a lathe, drilled, tapped, filed, sanded and polished. This gives us ultimate control over the timeframe and finished quality of these fan components.

4.0 Housing Inspection & Repair

Cracked equipment causes vibration that leads to inefficient and unsafe operations. With a thorough inspection, Our technicians can detect issues and bring equipment back to its original specifications.

5.0 Fan and Blade Balancing

By reducing the vibration, fan and blade balancing extends the life of your equipment. EMX’ Balancing Systems are designed to perform measurements of vibrations and calculations within horizontal shop balancing machines, and in the field. The fan and blade shall be dynamically balanced in a balance stand before assembly of the unit.

Fan Wheels are supported at the bearing position. Ref EASA AR 100 Dynamic balancing of the rotating element should be to the level specified by the customer. In the absence of a requested level, dynamic balancing to balance quality grade G2.5 (ISO 1940/1) should enable the machine to meet final vibration limits.
