Factors Involved In Determining Pump Performance

Factors Involved In Determining Pump Performance When working with pumps, you are sure to encounter instances where the pump curve is referenced along with a number of parameters associated with it.  A key parameter of the pump curve is the Best Efficiency Point (BEP).   For electric motors, efficiency varies with the load, the best [...]

Recording Motor Baselines Provides Early Warning Of Electric Motor Failures

Changes in motor / system vibration readings provide the best early warning of developing problems in the motor or system component.  Other parameters to monitor may include the operating temperature of critical components, mechanical tolerances, and overall system performance including outputs like flow rate, tonnage, and volume.  To avoid premature electric motor repairs, keep motor baseline [...]

How To Read An Electric Motor Nameplate

Knowing how to read the information on a motor nameplate will allow you to identify performance characteristics and applications of a motor, as well as potentially solve unexpected performance issues. NEMA requires the following information on a nameplate (although more info may be included) Frame Designation (FR) - this is typically a two or three [...]

Re-lubrication of Bearings

We've done several important articles about bearing lubrication (see them here and here).  It is an important issue, because faulty bearings are the cause of the majority the electric motor failures that come into our shop for repair. Lubricants are critical because they: Reduce wear Prevent corrosion Reduce heat Prevent contaminants To keep electric motors running [...]

Baseplates and Rotating Equipment Reliability

Many of the pump failures we see on a daily basis are caused due to an issue with a mechanical seal or bearing. The lifespan of seals and bearings will be dramatically reduced when shafts are misaligned or excess vibration is present. A sometimes overlooked cause of misalignment or vibration is due to the failure [...]

How To Grease A Bearing

If rolling bearings are to operate reliably and realize their full service life, the must be adequately lubricated. The function of the lubricant is to form a protective oil file that separates the bearing components and prevent metal to metal contact. The lubricant also protects the bearing and related components against corrosion. When grease is [...]

U.S. Department of Energy Funding Industrial Electric Motor Research

The U.S. Department of Energy is funding a three-year $6.7-million research project that could dramatically reduce energy consumption worldwide by developing more efficient industrial motors. Clemson University is leading the project together with TECO-Westinghouse Motor Company and Rensselaer Polytechnic Institute. Their goal is to reduce greenhouse gas emissions, while helping industry reduce costs and increase [...]
