Rotating Equipment
All you need to know about centrifugal pumps, Part 1
Understand these factors for reliable, optimal operation
Computational fluid dynamics: a key analytical tool
The potential for process improvements using these methods is not yet fully realized
Avoid control valve application problems with physics-based models
Kinetic energy criteria have many limitations
Consider precast polymer concrete pump foundations
Features include faster installation, improved corrosion resistance and lower vibration levels
Magnetic-drive pumps: technology and new applications
Developments in bearings, containment shells, magnets and cooling techniques improve reliability
Optimize gas turbine-driven centrifugal compressors
'Designed engineering' increases output by 100 - 500 kW
Easy way to estimate realistic control valve pressure drops
Use this method to ensure proper operation and minimize operating costs
Consider variable-speed, motor-driven compressors in refrigeration units
Depending upon ambient conditions and electricity prices, operating savings can justify the additional cost
