For many years a paper mill in the Southeast US was struggling with maintenance and reliability on their paper machine drive steam turbine. The current coupling in the system was a gear style which required routine maintenance, and, to make matters worse, required disassembly of the turbine gearbox in order to perform the maintenance. The […]
Faster Deliveries With Greater Energy Efficiency In their efforts to minimize inventory and maximize ROI, many companies have adopted just-in-time stocking practices. The warehouses and distribution centers that serve these companies have had to become fast and flexible. But, running conveyors and brake motors at full speed uses a tremendous amount of power — power […]
Armstrong large volume municipal booster sets have been installed to meet the domestic water requirements of more than 1,000 residential buildings in the West Shrouk City housing project in Cairo.
After a major refurbishment to guest suites and event spaces, managers at the Park Hyatt hotel wanted to improve heating efficiency and reduce energy use. Armstrong recommended replacing 1 of 2 existing pumps with a Design Envelope depm pump, to provide a head-to-head efficiency comparison. The new Design Envelope pump reduced energy usage by 60%. […]
TWAS can be much harder to mix than primary sludge, leading to disappointment and redesign. Computer simulation combined with a viscous sludge fluid model came to the rescue. The Vaughan Rotamix® mixing system for the blend tank at the Salmon Creek Wastewater Treatment Plant, Vancouver, WA, should have had plenty of mixing flow for stirring […]
When they think of renewable energy, most people think of solar and wind. And for good reason. The sun shines and the wind blows virtually everywhere in the world. But geothermal power generation requires fissures in the earth’s crust that allow heat from the earth’s mantle to turn groundwater into steam. The steam spins a […]
The evolution of variable frequency drive (VFD) technology stems from the need to boost motor control performance and to provide clean, efficient use of line power. Recent advancements in VFD technology have made way for a drive using Matrix technology. This white paper details the Matrix Drive’s innovative low harmonic and regenerative technology and compares […]
Precise Control of Equipment Maximizes Output, Minimizes Processing Costs Today, there are hundreds of types and blends of plastics, and they can be formed, molded, extruded, blown, and otherwise fashioned into a dizzying array of products. But at every stage of their processing — from the production of raw chemical ingredients; to their blending and […]
As a leading valve and automation provider, Flowserve has the resources to quickly turn around any repair or remanufacturing project, including plant shutdowns. Flowserve’s technicians and engineers are flow control experts. They specialize in repairing and upgrading engineered valve and automation packages — regardless of type or OEM — to extend service life and improve […]
P Series Pumps Exceed API 675 Performance Standards In 1994, the American Petroleum Institute (API) adapted its Standard 675 to stipulate performance characteristics for controlled-volume, positive displacement pumps. Although revised in 2010, and again in 2012, API 675 primarily defined metering pumps using mechanical stroke adjustment. Hydra-Cell Metering Solutions meet or exceed API 675 performance […]
The Push to Make Airports Green Spurred on by the promise of energy savings and reduced operating costs, America’s airports are taking a hard look at their equipment and procedures in an effort to become more “green”. The Promise of VFDs One of the most promising opportunities for reducing energy consumption in HVAC systems involves […]
