Energy Savings Through Pump Refurbishment and Coatings

Paul Maier, project manager of the NYSERDA study, states that “Pump sandblasting and coating should be a required step of any pump. refurbishment program.” MCWA has also included interior pump coatings as a requirement in its new pump specifications. The goal is that. requiring coatings on the inside of. new pumps will eliminate, or significantly delay, the seemingly inevitable decline in pump performance and efficiency from internal corrosion and tuberculation buildup inside unlined pumps.

Top Tips for Selecting Pressure Measurement Transmitters

When selecting pressure measurement transmitters, the first stage is whether to opt for a transducer or a transmitter. Although the terms are often confused, there are several differences between transducer and transmitter devices. A transducer creates a low-level electronic signal in response to changes in applied or differential pressure. As with transmitters, transducers feature an internal sensor that converts the applied force into an electrical signal, from which the measurement is derived.

Weibull Point Process Applied to Repairable Subsystems

Let’s suppose that we have recorded the time when each failure of a repairable subsystem has happened during a season. The arrangement of these failures (black points in Figure 1) along the time axis is called a stochastical realization of failure events.

Can You Really Justify Reliability Centered Maintenance (RCM)?

Reliability Centered Maintenance is a step-by-step instructional tool for how to analyze a system’s failure modes and define how to prevent or find those failures early. RCM become a very detailed study of things we already know, you will often hear the justification “it’s to make sure we don’t miss anything.” If you are considering implementing a reliability centered maintenance program, you. should be aware of the problems you may run into.

Corrective Maintenance Task Generation

Corrective Maintenance Task. Generation is best performed by the. same personnel who perform corrective maintenance. The normal. technician’s time schedule does not. allow the time to document tasks in. detail. Some companies rely on the maintenance supervisor to document. and implement new preventative and corrective maintenance tasks.

An Integrated Process for System Maintenance, Fault Diagnosis and Support

This paper presents an overview of an integrated process for system maintenance, fault diagnosis and support. The solution is based on Qualtech System, Inc.’s (QSI’s) TEAMS toolset for integrated diagnostics and involves several key innovations. As a showcase of the integrated solution, QSI, along with Antech Systems and Carnegie Mellon University (CMU), have recently completed a research project for the Information Technology Branch at the Naval Air Warfare Center–Aircraft Division (NAWC-AD) in St. Inigoes, MD. The entire system, termed ADAPTS (Adaptive Diagnostic And Personalized Technical Support), provides a comprehensive solution to integrated maintenance and training.

Does Lubrication Belong in the CMMS?

Most, if not all, companies use CMMS systems to oversee their maintenance activities. From home-grown systems to complete ERP systems, leveraging technology allows companies to more efficiently and effectively manage their maintenance, repair and operations activities. So as a core maintenance function, surely routine, lubrication-related preventive and predictive activities such as regreasing motor bearings, taking oil samples, and executing oil top-offs and inspections belong in the CMMS system like any other maintenance task, right?
