Pump monitoring instrumentation is often not included with installations, but proper sensors can protect a pump and help with efficient operation.
This article will define a business case for achieving significant rotating equipment maintenance and energy cost reduction at industrial and municipal facilities.
Water system operators know the challenges of keeping municipal drinking water consistently and safely chlorinated. Increased safety concerns regarding common disinfectants and mandated chlorine residual targets make maintaining large or small water systems difficult.
While it is valid to state that energy efficiency is defined as the same level of production achieved at an overall lower energy cost, it is equally important for today's machine builders and automation engineers to remember an energy efficient system can actually translate into higher productivity. This is achievable through a comprehensive approach to energy management.
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.
Many items must be considered when designing pump station control systems with power requirements, level control method and control panel location often among the most important.
Economic pressures to minimize production downtime and improve operating efficiency are increasing the emphasis to accomplish on-site problem detection, analysis, and resolution as fast as possible. These requirements place a great deal of pressure on maintenance personnel to have all the right tools readily available in one place.
Explore hermetically sealed gauging probes for hostile environments like saw mills and wood processing plants.
A crucial triumvirate for improving the bottom line. pump system optimization, pump efficiency
If pump cavitation is not detected and quickly eliminated, significant damage can occur to the impeller and other internal components. Since cavitation (the formation and collapse of vapor bubbles in the pumped fluid as it passes through the pump impeller) is often temporary or even induced by the process, timely knowledge of the condition is extremely important so operators can act to alleviate the problem and prevent damage.
A Nashville-based hunting club required the flooding of several acres of land. A shallow area approximately 1.5-ft deep needed to be flooded to help attract wild game.
Most VFD systems use some form of closed-loop feedback to avoid surging, excessive noise, and in extreme cases, vibration. A reliable encoder signal is one method that minimizes speed variance and helps eliminate these unwanted effects. Here's how it works.
Back in the old days, level control had little or nothing to do with saving energy. In fact, it was often a necessary evil. Today, that is no longer true - the VFD offers the potential for power savings in lift station applications that range from a few hundred gallons per minute to those that have to move thousands of gallons each minute.
One electrical equipment specialist is relying on a cleaning system to ensure that a variety of stamped and turned parts are thoroughly degreased at their production facility.
When measuring vibration, one of the most important factors in obtaining accurate information involves selecting the proper vibration transducer. Selecting the wrong vibration transducer can yield results that are misleading or, worse, mask a problem.
Questions are answered about monitoring power consumption and noise level parameters for pumps.
Your company has recently purchased a laser based alignment system. Your newly trained technicians are asked to align a critical process pump. You witness the alignment. They save the final alignment data. You review the data, but what does it mean? How does it compare to dial indicators? Why did they rotate both shafts when measuring the misalignment? Why are the numbers at the feet higher than you would like? How do you KNOW the alignment is good? The debate begins.
Here is a primer on the proper locations for surge protection in water and wastewater facilities.
When the City of Delaware, Ohio, expanded its wastewater treatment plant, it looked to increase more than just capacity. It also wanted to increase its efficiency and automation capabilities to benefit the plant's operators and taxpayers.
