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

Identifying the source of vibration by following the amplitude: the case of a company that thought the problem was a pump impeller, but, in fact, the problem was over 15-ft away and not a pump at all.

Introduced in August 2008, the Retroflo RPC_2000 Pump Control System was designed to control pump stations as a whole, rather than just the individual components within them. Through continuous dynamic monitoring of the characteristics through a range of wet well levels and pump speeds, the system uses the full range of pumping data available to optimize performance. It can be retrofitted to existing stations or installed in new stations.

Since municipal codes frequently deal with the most crucial areas of public life-covering the safety of life and property-it is understandable that preference is given to tools and methods that are "tried and true" over ones that are untested. The challenge becomes how to take advantage of new advances in technology while recognizing the importance of maintaining an uncompromising level of safety and security. The answer can lie in close cooperation between officials who champion the integrity of the municipal code system and individuals experienced in the implementation of innovative technologies.

Increased efficiency, higher air handling and fast, automatic priming are provided with new technology.

Dynamic pressure sensors and accelerometers are frequently used for precision measurements in oil, gas and petrochemical industries, as well as for natural gas supply monitoring applications. The development of piezoelectric sensor technology with integral charge amplifier, as well as the development of high temperature charge output designs, has been especially important for dynamic sensing applications. To truly understand the benefits of this technology, one must first review the evolution of this type of sensing.

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.

As a public water provider, Loudon Water, a water and wastewater authority in Loudon, Va., must be able to supply water to meet the community's needs.

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

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.

When it comes to pressure and flow, variable speed pumping applications can be divided into three basic categories. Constant pressure-variable flow (Cp-Vf) attempts to keep pressure relatively constant over a range of flows. Constant flow-variable pressure (Cf-Vp) tries to achieve the opposite by using varying pressure to keep flow constant. Variable pressure-variable flow (Vp-Vf) applications can accommodate a change in both.

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.

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.
