Lubricated machines require clean, dry oil to work properly.

Enveloping is a tool that can give more information about the life and health of important plant assets. It is primarily used for early detection of faults in rolling element bearings and gearboxes. Enveloped acceleration is an especially valuable parameter to trend, as the progression of machine condition can be evaluated. Armed with good information and assisted by service experts, plant engineers can be confident in the proper operation and management of the important assets in their care.

Although the use of transmitters in pressure measurement is growing, mechanical pressure gauges are still used on most systems as local pressure display to back up electrical readings. The selection and installation of these gauges can be difficult in certain locations. Harsh conditions that can require special consideration include vibration, pressure pulsation, overpressure, corrosive media and extreme process and ambient temperatures. This article is designed to address harsh conditions with best practice recommendations to extend gauge life and provide for the safest installation possible.

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

Of the technologies available for condition monitoring of rotating equipment, the quickest return on investment is from vibration analysis. For the novice, vibration data seems complex and is generally difficult to assess compared to other techniques. Once trained, however, the novice can recognize the patterns and diagnose a machine problem.

Pressure gauges are a versatile way to monitor pump operation.

Last month we reviewed the pump selection criteria for a closed loop circulation system (Vp-Vf). This month we will take a look at a similar application that adds some elevation to the equation.

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.

Pumps are sent to rebuilding and remanufacturing companies because buying new can be expensive and require long lead times. For instance, a 39 in diameter, 1,000 lb bronze impeller may cost $28,000 and take many weeks to deliver. In these cases, the impellers involved in an overhaul are often built back up to the required specifications and rebalanced.

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.

Growing infrastructures are creating more complex problems for municipalities than ever before, forcing them to search for a diverse range of system solutions to issues involving energy savings, maintenance savings and total life cycle cost analysis.

Frequency Hopping Spread Spectrum (FHSS) radio was invented during World War II by the military for communicating information and strategic plans to allied forces in a way that would counter enemy efforts to "jam" or intercept traditional radio communication frequencies.

Holistic pump system designs optimize system efficiency and life cycle performance.

The service department of a variable frequency drives manufacturer frequently sees the following scenario: A frustrated user calls with what he perceives to be a defective piece of equipment. As the technician begins probing for information, the user's frustration boils over, often with an exclamation along the lines of "what a piece of junk!" As the service technician asks the pertinent questions, the exasperated user relays the details of a drive that is continually tripping on a fault until the user is at the end of his rope, not knowing what to do.

"An ounce of prevention is worth a pound of cure" may have been coined by process and plant engineers tired of repairing or replacing pumps. Pumps are often the most under-serviced pieces of equipment in process automation when it comes to maintenance and prevention best practices. Unfortunately, nothing moves without the humble pump, and a process becomes inefficient when a pump doesn't operate properly or completely shuts down. Many times the pump manufacturer is seen to be the problem, when in fact the process or the surrounding equipment configuration is the cause.

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.

It required only a couple notes of the haunting soundtrack to signal an imminent shark attack in the movie Jaws. As the theme began to swell, it became obvious that someone was going to “get it.” It would be nice to have a sixth sense that allowed us to hear "warning" music in daily situations. Condition monitoring systems provide a means of sensing when sharks are skulking toward your critical machines.

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

How a monitoring alarm system with control and shutdown capabilities prevented costly pump damage and environmental hazards and made the job of the pump operator safer and easier.

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