Proper condition monitoring and intervention could have prevented a pump breakdown

August 29, 2012

PUMPS & SYSTEMS • August 2012 By James Laxson,  Hi-Speed Industrial Services in collaboration with Mike Fitch,  LUDECA, Inc. In May 2010, an electric motor repair service provider in Little Rock, AR, began a condition monitoring program for a new customer. The customer opted for quarterly data collection. Read the article Pump Train Component Failure, […]

Setting the proper Lines of Resolution (LOR) is essential for effective vibration analysis

August 20, 2012

Setting the proper LOR is essential to be able to separate closely spaced defect frequencies.  An example would be a pump with 5 vanes that could generate a “Vane Pass” frequency equal to the number of vanes,  or 5 times rotational speed; if the impeller end of the pump had an SKF 7301BEP bearing, it could […]

Overall Vibration Values versus Band Alarms, which to use?

August 15, 2012

Overall values are the most common measurements and calculations used in vibration analysis. The purpose of this measurement and calculation is to identify changes in the condition of the equipment being measured. Overall measurements are an important tool for the vibration analyst. However,  generic overall values can actually be deceptive if their limitations are not […]

Don’t Forget Gear Coupling Lubrication

August 8, 2012

When machines are set in place,  aligned,  and buttoned down, it becomes too easy to forget about the gear couplings that may be used to transmit power between the machines. Gear couplings are tough workhorses that perform well in many applications because they operate quietly and efficiently. Since they are so reliable, we tend to […]

Cooling Company Stays Cool with Condition Monitoring

August 6, 2012

An air conditioning and heating systems manufacturer in Texas is challenged to continue providing the industry with leading products,  while meeting high-reliability standards, maintaining affordable prices, and meeting increasing worldwide demand for the products they manufacture.  All of this must be done in a way that provides the expected financial return for stakeholders.  An internal […]

Advanced Alignment Data Collection Methods in High-Vibration Environments

August 1, 2012

Alignment readings, whether they are taken with dial indicators, or high precision laser shaft alignment equipment, can be susceptible to outside interference. Among the most notable of these circumstances is high vibration coming off of equipment that is next to, or nearby, the machinery that is currently being aligned. Dial indicators can fluctuate several thousandths; […]
