Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

Determine forces on the valve spool to optimize solenoid size. Designers of spool-type, solenoid-operated hydraulic valves often face the vexing problem of increasing flow while shrinking the size of ...

A novel approach using computational fluid dynamics techniques provides a way for determining the characteristics of gas passing through a gas-lift valve. In the method, CFD calculations numerically ...

Beyond the wheel, the most important mechanical equipment serving humanity is the centrifugal pump. Centrifugal pumps make modern quality of life possible. Turn on a faucet and a centrifugal turbine ...
