Clarke Industrial Signs Valve Deal for Major Industries
Curtiss-Wright licenses Shutter Valve technology for several major industries.
Lithium Recovery from Oil Brine
Production time for recovering lithium from heavy oil wastewater is reduced 99% compared with the use of solar evaporation technology.
Hydraulic Fracturing Fluids Change Water Chemistry in Gas Wells
A multidisciplinary team of researchers from Penn State has discovered that pressure, temperature and fluid composition significantly affect the amount of metals and other chemical found in hydrofracking wastewater.
Researchers: Hydraulic Fracturing Boosts Local Economies
The first nationwide study of the comprehensive local impacts of hydraulic fracturing finds that when costs and benefits are added up, communities on average benefit from allowing it.
What to Look For in a Thermal Design Solution
Computational fluid dynamics enable engineers to model thermal responses including all the modes of heat transfer, namely conduction, convection and radiation. The results can be used to judge component and environment design viability.
LevelGuard Pump Switch Passes 3.5 Million Cycles in Test
Four LevelGuard Pump Switches are currently available, including a sewage model, with 9-foot and 15-foot cords that use piggy-back plugs, as well as a 30-foot pigtail cord.
HVAC Design Changes May Enhance Energy Efficiency
Samsung says it is working toward enhancing efficiency in heating, ventilating and air conditioning systems through design.
Purifying Water for Schools in Developing Countries
The point-of-use slow sand filters are made from readily available five-gallon plastic pails or 55-gallon drums.
Engineer's Guide to Boiler Tube Inspections
Coupled with diligent in-service observations, appropriate and opportune inspections are essential to identify boiler component damages, mitigate failures and maximize availability.
Air Squared Wins a Demo Project for the U.S. Navy
Air Squared proposes to combine a turbomolecular backing pump with two-stage scroll vacuum pump acting as a roughing pump.
Variable-displacement Pump Control Basics
Variable-displacement piston pumps provide flow dependent on a rotating group of pistons.
Engineers' Guide to Hydraulic Oils and Transmission Fluids
Hydraulic oils and transmission fluids transmit power in hydraulic equipment and are used in power transmission applications.
Robotics Are Activated with Vacuum to Enhance Safety
Actuator mimics skeletal muscle movement and uses vacuum power to automate soft rubber beams.
Automated Inspection for High-Speed Manufacturing
Automated inspection vision systems are an important tool for any web-based manufacturer looking to improve product quality, reduce costs and further automate production.
Consider Pressure Drop When Sizing Injection Pumps
Chemical injection pumps charged with injecting fluids into a pipe must be properly sized in order to overcome the pressure in the pipe.
Servos Can Help Prevent Machines from Falling Down
Eccentricity machined into rolls can cause wobble—defined as the angular deviation of the axis of rotation over one revolution.
Pumping in Parallel Is Not Always Simple
Inadequate flow rate often plagues two-pump systems, particularly in plants that are more than 10 years old.
Selecting the Right Vacuum Pump for the Job
Laboratory managers specifying vacuum pumps have much to consider when evaluating the four basic types of pumps.
A Flush Plan May Help Optimize Seal Life
Circulating fluid to or from the seal chamber will maintain proper lubrication, pressure, temperature and solids management.
Refinery Installs Compact Plunger Pumps
The pumps use an in-line gearbox and B5-flange mounted motor.
