Keeping the diverse requirements of customers in mind, we are instrumental in providing Intelligent Machine Monitor.
Large Fans and Blowers (ID, FD, SA, PA etc.) are used in process plants for moving air or gases; they are essential for cooling, heating or transporting product. They usually are centrifugal or axial driven and commonly develop erosion and/or corrosion and/or deposition on the blades. This results in a progressive increase in vibrations. And build-up of dirt or cake on a fan’s impellor is quite normal. However, not always are these faults progressive and predictive but, should a dirt piece become detached then suddenly the rotor becomes out of balance, and if ignored, consequential damage to the drive motor’s bearings and coupling will result. This can be extremely destructive and threaten personnel and plant safety The loss of asingle line Fan or Blower can shut down the process causing significant production and financial losses The eMT Intelligent MACHINE MONITOR is smart to detect and measure low energy bearing defect energy signals in addition to overall machine vibration and machine temperature of fans and blowers. Alarm and Trip levels can be independently set for each parameter and thus protects the machines on continuous basis by giving an early warning to prevent sudden machine failure resulting into process failure and consequential loss of production and is thus a boon to the industry.The re-transmission analogue signal can be trended in DCS/PLC to monitor defect progression and plan maintenance considering production schedule and fix the problem before catastrophic failure.Typical Measurement Positions:
Locating the vibration sensors as indicated in the schematic will be most sensitive and effective indetecting the above faults listed. The sensor orientations are summarized as follows:
- HORIZONTAL on two motor bearings (A & B) and two fan bearings (C&D). B&C ideally recommended
- VERTICAL on motor & fan drive end bearings (B&C).
- AXIAL on motor & fan drive end bearings (B&C). B or C is recommended
