Increase Pump Uptime, Decrease Costs With Water Management System For Mechanical Seals

by Chris Rehmann

Rising cost and shrinking availability of clean water for operating industrial pumps are of concern to many plant managers, as is as the high cost of treating this water for disposal.  For over a half-century, the accepted method of providing cooling and flush water for mechanical seals and packing has been to pipe plant water through the seal or packing, and then to drain.  Under this scenario, the normal consumption of water is 1.7 million gallons of water per pump, per year. 

Looking Back to See the Future

I recall a pump failure that occurred in the early years of my career. I was part of the mechanical equipment group in a large refinery. We received a call telling us that the transfer pump next to one of the tanks in the tank farm was not working and they needed it fixed immediately. For some reason, a mechanical engineer was the first person sent out to determine what was wrong so I got to see things from a different perspective.

Managing a Successful Condition Monitoring Program

Managing a successful condition monitoring program may seem easy to begin with. The technologies may be presented (by the sales companies) as being easy to use, and with a number of the technologies, it is not immediately obvious if they are not being used correctly. In the early days of a program, fault conditions will be easier to detect (there are probably a lot of them) so it is likely that management will be pleased with the results.

PdM Centralization for Significant Energy Savings

Dale P. Smith, CMRP
Predictive Service, LLC

Abstract

All facilities lose energy dollars through overheated electrical distribution systems, overloaded and misaligned rotating assets as well as lose expensive compressed air and steam through leaking pipes/fittings. Couple this with the increasing pressures of global competition, thinning workforce, and budget constraints are forcing us to improve equipment reliability by fully leveraging predictive maintenance (PdM) technologies.

This paper focuses on how the successful integration of standard PdM technologies can capture significant energy savings and simplify ROI calculations. By the way, any associated benefits of increased safety, reliability and enhanced facility capacity are purely coincidental.

Predictive Maintenance ROI for Waste Water Treatment Facilities

Presented by Saul Cizek

Basic Premises

Understanding that the world is not logical, organized or consistent is fundamental to improving maintenance applications for industry. The moment our cave dwelling ancestors had a chance to pause and reflect in relative safety marked the beginning of philosophical thinking. No doubt, these ancestors realized in some fashion that organization is a key to survival. They might also realize that substantial knowledge was important. With the power of organization and the power of substance recognized the age of enlightenment is born.

Procedure for establishing an effective Oil Analysis program

Oil is often times known as the bloodline of industrial facilities. Defining oil in this manner definitely emphasizes the importance it has on the health of equipment. So just how much do you know about your oil?

Pump Bearing Distress & Seal Failure New Statistics on the Value of Bearing Housing Protection

By: Heinz Bloch & Alan Roddis

It has been known for years that bearing malfunction often precedes mechanical seal failure in centrifugal process pumps. Statistical information to that effect has recently been published in a technical paper; it facilitates assessing the benefits of sound remedial action. The data of interest were presented at the Mechanical Sealing Technology Seminar, IMechE, London under the title "Mechanical Seal Reliability - What Realistically can be Achieved"1.

Reliability Improvement for the New Millenium

By Chris Traianou

In an increasingly litigious world, providers of utilities and services must do everything they can to ensure uninterrupted provision of water, sewerage, electric power or gas.

Road to Gold

Hamilton Sunstrand quest to achieve UTC's Ace Gold Status by Steven Piazza, Hamilton Sunstrand (Winner Uptime Magazine PdM Program of Year Award Best Ultrasound Program for 2007)

The maintenance aspect of our jobs would be easy if we could have the advanced knowledge of machinery and equipment failures. By closely predicting the life cycle of parts and equipment it would be simple to schedule the repairs and the replacement of equipment and manufacturing systems. As we all know, accurate and timely scheduling team up to drive the effectiveness and efficiency of our maintenance resources.

Rolling Element Bearing Acceptance and Life Testing

The Rolling Element Bearing Acceptance Test (BAT) includes, the testing Methodology, the Testing Apparatus and the Software that are used to predict the Relative Bearing Life (RBL) from the results of a non-destructive, impact hammer test of the bearings. These results are to be taken from a well known procedure of modal parameter identification and extraction using Vibration Analyzers, hammer, and response transducer. The Important feature of (BAT) is its capability of obtaining Relative Bearing Life of bearings (new or used) which are to be tested together with a known life bearing called (Reference bearing). The results of tests can compare the life of any tested bearing to the life of the Reference Bearing. The software, hardware(s) and Methodology are explained in figs 1,2 and 3 together with the description and procedure.

SKF Predictive Maintenance (PdM) Benefits Overall Maintenance Strategy at Linde Gas Plants in China

The Linde Group is a world leading gases and engineering company operating in more than 100 countries. With such large and widespread successful operations it is no surprise that maintenance activities are well run and that the company is no stranger to advanced monitoring techniques and equipment. In USA and UK particularly, but also elsewhere in the world, on-line machine monitoring has been used for a number of years at Linde plants. And, at its Shanghai headquarters it has a large and impressive ‘remote operations centre' where it monitors and tracks the process operations of all it's major gas plants in China 24 hours a day.

Successful Solution to the Challenge of Low RPM Bearing Monitoring

By Tim Sundström

Low RPM applications have been notoriously difficult to monitor with traditional vibration-based techniques. The energy involved at RPMs below 50 is very low, making it a difficult task to extract meaningful information from the measured signal.

Taking Charge

Increase Safety & Reliability with Integrative Predictive Maintenance

by  Dale P. Smith, CMRP

MaintenanceElectricity, and its uninterrupted distribution through our nation, facilities and lives, is an inescapable requirement and the backbone of progress in today’s society.  The resurgence of US commerce is not possible without it.  Safe and reliable electrical distribution systems typically start out as being well engineered, with bright futures provided they receive regular, adequate maintenance and periodic testing.
