Cost Justification Worksheet For Motors

“On the plant floor, when it comes to a failed motor, the expense of the repair or replacement is, in reality, a minor cost. The real cost is in the downtime, labor, loss of production and disruption of production schedules.”

Rock Island, IL (PRWEB) December 3, 2009

Inpro/Seal Company has revised its Cost Justification Worksheet (CJW) For Motors. This Excel module identifies energy and operational savings a plant can attain through the use of bearing isolators.

UNIQUE REFERENCE
The Inpro/Seal CJW is a valuable tool for top management, engineering, operations, maintenance and other professionals involved in the maintenance, repair and operation (MRO) of motors for industrial and process applications. The elements of this module can also be used with pumps, machine tool spindles, turbines, fans, gear boxes, paper machine rolls, conveyors, shafts, VFDs and other types of rotating equipment.

EASY TO CONFIGURE ROI CALCULATOR
End users simply supply the number of motors, current costs to repair and other pertinent performance data. The CJW allows plants to calculate their own ROI (return on investment) factoring in the use of bearing isolators, including benchmarks of current repair costs and ways to increase the reliability of their rotating equipment.

The CJW also includes such information as: accumulated savings; total investment; net return; data for life-cycle costing; the use of more efficient motors; net costs to run motors more efficiently; and more. The benchmarking of Bearing Isolator performance referenced in the CJW relies on data compiled from thousands of actual bearing isolator applications.

THE BEARING ISOLATOR
In his quest to find a permanent means of protecting bearings while enhancing and extending the service life of rotating equipment, David C. Orlowski developed the worlds first Bearing Isolator. Patented in 1977 (#4,022,479), the year he founded Inpro/Seal, the Bearing Isolator (a term coined by Orlowski) finally gave process plants permanent bearing protection while eliminating the need for continual maintenance.

The Inpro/Seal Bearing Isolator is a non-contacting labyrinth seal comprised of a unitized rotor and stator that do not contact one another. It does not consume energy, never wears out, and it can be used over and over for many years. Protected bearings have proven to run 150,000 hours (17 years) or more; Bearing Isolators eliminate costly maintenance and repair.

PROTECTED BEARINGS SAVE DOLLARS AND MOTORS
According to Orlowski, “On the plant floor, when it comes to a failed motor, the expense of the repair or replacement is, in reality, a minor cost. With process industry downtime running as high as $80,000 per hour, the real cost is in the downtime, labor, loss of production and disruption of production schedules.”

“With over three decades of experience working with OEMs and end users,” Orlowski continues, “we know what it takes to keep motors running. We also know that contact seals, fibrous packing, flingers, lip seals, labyrinth seals, ‘sealed for life’ bearings and other devices simply do not keep out contaminants over time. To attain the highest levels of protection and eliminate more than half of all motor breakdowns, all an end user has to do is install Inpro/Seal Bearing Isolators. The Cost Justification Worksheet For Motors shows how important this product can be to a plant’s bottom line”.

Orlowski concludes, “Protect your bearings and you’ll save your motors–it’s as simple as that. Once installed, Bearing Isolators have proven to eliminate the root causes of motor failure: moisture, dirt and abrasives contaminating the bearing environment.”

BEARING ISOLATORS AND IEEE-841 MOTORS
Recognizing the importance of motor bearing protection, the IEEE began to recommend the use of bearing protection and developed a specification that evolved into the IEEE motor, which offers at least twice the reliability of other motors. As part of its specification, all IEEE-841 motors incorporate Inpro/Seal™ Bearing Isolators as standard equipment. The newer NEMA Premium motor, which has at least a one point energy edge, is available with Inpro/Seal Bearing Isolators as a standard option.

NEWEST BEARING ISOLATORS FOR MOTORS
Earlier this year, Inpro/Seal unveiled its Motor Grounding Seal (MGS) and Current Diverter Ring (CDR) to deal with the damaging effects of shaft current on motors controlled by Variable Frequency Drives (VFDs). VFD systems inherently generate residual shaft current or shaft voltage that accumulates on the rotor and discharges (shaft to frame) through the motor bearing. This random and frequent discharging is referred to as the EDM effect, a phenomenon that causes pitting on the bearing’s rolling elements and raceways and leads to destructive bearing failure.

The MGS and CDR–an enhanced Bearing Isolator–eliminate this damaging shaft current by providing a "virtual short" between the shaft and motor frame that keeps shaft current and voltage from building up before bearing damage can occur. The MGS prevents pitting, fluting and fusion craters to eliminate catastrophic motor failure while permanently protecting bearings from contamination. Its key component, the CDR (available as a separate component) works to keep damaging shaft currents away from coupled equipment.

New Inpro/Seal Literature

Inpro/Seal Company, the worldÂs largest producer of industrial bearing isolators, has published literature that provides a detailed overview of its Bearing Isolators and Bearing Isolator-based shaft seals

The Inpro/Seal CDR Ring

A bearing protection device, the CDR prevents contamination from entering the motor bearing enclosure of VFD controlled motors and impedes stray shaft currents from traveling to coupled equipment such as rotary feed valves, mixers, blenders, agitators, pumps, fans and related centrifugal equipment.

Water Mizer Shaft Seal

Using A Water Barrier, The Inpro/Seal Water Mizer Shaft Seal Provides Sealing Efficiencies Other Methods Cannot Attain. No Moving Parts, No Friction, No Wear, No Contact, No Energy Consumption.

The Inpro/Seal manufacturing complex is the largest of its kind in the world devoted to the engineering, research, improvement, testing and manufacture of bearing isolators.

Green Is The Color

The OM32 Series was developed exclusively for Oil Mist applications to contain stray mist and keeping it from entering the environment. Once installed end users receive levels of protection previously unattainable. With the oil mist bearing isolator, the lubricant is coalesced to a liquid and drains back into a system sump or reservoir instead of into the environment. Bearings are protected, shafts are sealed and environmental housekeeping problems are solved.

The Mine Safety and Health Administration (MSHA) has recognized Inpro/SealÂs Belt Conveyor Idler/Roller Bearing Isolator, assigned it tag #AP2007-93304 and posted it on their websiteÂ www.msha.gov. Once installed it will protect idler bearings in mining operations and provide additional safety and reliability.

While they are engaged with a rotating shaft and effectively sealing, contact seals, including lip seals and face seals, consume significant energy. According to industry sources, that rate of power consumption is, on average, 147 watts per seal.

Inpro/Seal, the manufacturer of bearing isolators, has significantly revised - www.inpro-seal.com - their long standing website. Dedicated solely to bearing protection technology, it is the only website devoted exclusively to bearing isolator technology and incorporates illustrations, charts, diagrams, installations, product photography, documentation, product literature, feature articles, FAQÂs, guarantees and much more into a product rich website designed to educate, inform and simplify the bearing isolator selection process.

The VBXX-DÂ is the next generation in Inpro/SealÂs bearing isolators. It offers the latest and best non-contacting labyrinth sealing technology to improve plant uptime and reliability with levels of bearing protection previously unavailable. It is the only bearing isolator on the market with a vapor blocking ring that provides a barrier to keep humidity from entering the bearing enclosure. With no friction wear, it may well last past itÂs documented 20 year service life and last indefinitely. Only time will tell.

Brochure details the misapplication of lip seals and why they should not be installed on rotating equipment. Written for maintenance, repair and operations personnel at process plants, it goes on to provide information on the History Of Lip Seals, Lip Seals In The Mechanical Universe, Life Cycle Aspects, 100% Failure Rate, Misapplication, Real Costs, The Real World, Alternatives, Permanent Bearing Protection and much more, as well as charts, graphs and illustrations.

This is a brochure, authored by David C. Orlowski, well known for his knowledge of bearings, bearing protection and tribilogy and the inventor of the bearing isolator. It is a valuable source of information and useful tool to anyone involved in the management, maintenance, repair and operations (MRO) of motors, machine tool spindles, turbines, fans, gear boxes, paper machine rolls, pumps and other types of rotating equipment used in industrial/process plants. It includes important and useful information on the evolution of the bearing isolator, including: how and why it was invented; how it works; how and why contact seals fail in a short period of time; how to eliminate catastrophic failure; how to reduce power consumption in rotating equipment; costs; maintenance; configurations and much more.

The Inpro/Seal bearing isolator is a permanent replacement for contact seals that wear out in a matter of months.

The Air MizerÂ-PS was developed to seal shafts where dry particulates, powders and bulk solids are handled, processed, packaged and stored. Examples include: screw conveyors, mixers, blenders, rotary valves, feeders and related.

The bearing isolator is a non-contact, non-wearing, permanent bearing protection device. It has a rotor and a stator, and the two are unitized so that they donÂt separate from one another while in use. Typically, the rotor turns with the rotating shaft, while the stator is pressed into a bearing housing. The two components interact to keep contamination out of the bearing enclosure and the lubricant in. While a lip seal or contact seal operates with contact, the bearing isolator makes no contact, never wears out and can be used over and over for many years. Contact seals, on the other hand, have a 100% failure rate.
