While scheduled downtime is different from unscheduled, both can take away from a company.

Data and life cycle management technology helps refineries maintain equipment and reduce the total cost of ownership.

Precision laser alignment can help end users avoid multiple problems in wind turbine applications.

Soft foot is one of the most prevalent conditions found in rotating machinery. This condition, if not corrected, makes an alignment job much more difficult and sometimes impossible. If the internal alignment is not correct, the external alignment will not matter.

In my experience, there are three types of maintenance philosophy regarding vibration programs: No philosophy at all, utmost attention with zeal, attention to particularly problematic units

With the growth of wind farms, users are turning to condition monitoring and automatic lubrication systems for increased reliability.

The past may be prologue to the future, but the time between the two seems increasingly short. In the past, labor, capital and raw materials were considered the underpinnings of wealth creation. Today, real-time process knowledge and innovative management strategies have become far more important for creating value, as evident in the headlines above. Accordingly, the time for systemic change is now. . . the opportunity to reinvent industrial manufacturing and the products and services that surround it have never been greater since the beginning of the industrial revolution.

Beating occurs when two dynamic excitation sources (forces) are close together in frequency, and a pathway allows the two excitation forces to transfer to each other. The beating effect results because the frequencies are so close to each other that the waveforms alternately reinforce each other at some times and cancel each other at other times. When the vibration from each source adds constructively, the vibration increases. When the vibration adds destructively, the vibration decreases.

VFDs replace mechanical devices and PLCs for lead-lag pump control.

Any time a measuring instrument is used in a plant, it is expected to provide reliable results.

Electric drives are used in various applications in the oil and gas industry for varying motor speeds driving critical components, including pumps, fans and compressors.

Questions are answered about monitoring power consumption and noise level parameters for pumps.

An automated monitor provides a live, continuous picture of exactly what is happening inside a turbine for protection, prediction, performance monitoring, and integration of the data with process control.

Starting can have a significant effect on the life of the winding insulation of an AC motor.

Explore best practices for securing SCADA systems in remote sites. This article addresses threats and corresponding implementation measures with a focus on SCADA RTU installations and the processes they monitor and control.

In today's growing industrialized market, the need for reciprocating pumps is increasing daily. As technology drives modernization, the demand placed on the pumping systems is continually rising.

Yuba County Water Agency in Marysville, Calif., recently chose a wireless system as a solution for a water pump problem. Here are some of benefits they discovered.

Last month we reviewed the pump selection criteria for a typical constant pressure-variable flow (Cp-Vf) application that utilized variable speed (VFD) control. This month we will explore an application where pressure varies in proportion to a change in flow.

As oil prices and gasoline usage have increased, the demands on U.S. oil and gas wells have grown dramatically. In the past, there was a low cost supply from the Middle East, and U.S. oil wells were not used as frequently due to low reservoirs and the energy cost associated with extracting the oil. A large number of U.S. wells were shut down in reaction to high electric costs, low oil prices, the need for monitoring the oil reservoir and machine maintenance. As of 2004, there were just over 800,000 onshore oil wells in the world, with about two-thirds of them in the United States.
