Monitoring vibration—a valuable tool in predictive/preventive maintenance programs

Named after frontiersman Kit Carson, Carson City, Nev., is known for its fresh air, rugged natural surroundings and its proximity to the casinos of Reno and skiing in Lake Tahoe. Carson City, the capital of Nevada, has been a self-governing municipality since 1972. The Carson City Public Works Dept. manages all the water for Carson City and County. Its mission is to be completely self-sufficient-acquiring, using and reusing 100 percent of its own water.

Find the right flow meter for your process and plant.

Explore hermetically sealed gauging probes for hostile environments like saw mills and wood processing plants.

Variable frequency drive technology is more efficient and accurate, which leads to increased energy savings.

Last month, we discussed thermal radiation and material properties and the thermal nature of materials. We also looked at the emissivity of real objects using a stainless steel block. This month, we will discuss other characteristics demonstrated by the steel block example.

A sewage lift pump that pumps millions of gallons per day simply can't go down. To prevent this from happening, this pair of electricians went about testing some new electrical systems for those pumps with a new insulation multimeter.

Released in January 2010, the SDT270 Ultrasonic Detector, in conjunction with its powerful database software, gives the earliest indication of bearing re-lubrication requirements, bearing failure, and pump cavitation.

In the U.S. industrial sector, motor-driven systems consume 70 percent of all electricity. Motor-driven pumps account for more than 30 percent of that amount-more than any other application. Considering energy and maintenance represent more than 80 percent of total motor life cycle costs, a growing number of system designers, specifying engineers, maintenance professionals and end users are turning to variable speed motor control systems that can save up to 60 percent in energy costs as well as significantly reduce maintenance and equipment costs, improve process control and enhance system reliability.

Why question the PLC? For many, questioning the application of a PLC to the pump station panel is surprising. After all, the pump station panel was once controlled with a range of relays, timers, and other devices - the exact type of application where the PLC has had such success in industrial automation. pump efficiency

Explore the current condition of SCADA reports and some new technology that will improve the quality of those reports.

Pressure gauges are a versatile way to monitor pump operation.

Gulf Chemical & Metallurgical Corporation (Freeport, Texas), a subsidiary of the Eramet Group, is a recycler of spent petroleum catalysts and a leading producer of ferroalloys. The company applies hydrometallurgical and pyrometallurgical operations to recover molybdenum, vanadium, nickel and cobalt for reuse by major catalyst producers and steel manufacturers. Embarking on the road to improved equipment reliability represents a key aspect of a concerted strategic initiative for Gulf Chemical. The introduction of wireless technology and additional support has yielded successful outcomes for its facility.

Choosing the right differential pressure flow meter for an application can be challenging. This article outlines the considerations and trade-offs in selecting the optimal technology.

Industry analysts predict that in the near future, most motors will be controlled by variable frequency drives. Here are the reasons why.

When selecting a pump for variable speed operation, a number of conditions must be evaluated.

The next generation solution for variable speed pumping applications are variable frequency drives (VFDs) with integrated advanced pumping software that solves various control applications without the need for a PLC or separate controller.

The second part of this three-part series explores the types of protection applied to specific equipment installed at water and wastewater facilities and some typical criteria used to develop protective settings.

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

Read how WirelessHART can be implemented in large process plants despite the distances needed for the network.
